The following describes the door assembly 100 of the refrigerator 700 and the refrigerator 700 according to the embodiment of the present invention with reference to FIGS. 1-6 .

As shown in FIGS. 1-6 , the door body assembly 100 of a refrigerator 700 according to an embodiment of the present invention includes: a door body 10 , a hinge fixing plate 20 , a hinge shaft 30 , a shaft sleeve 40 , a limit Position piece 60 and screw rod 50.

Specifically, as shown in FIGS. 1-6 , the hinge fixing plate 20 is spaced apart from the door body 10 , and the hinge shaft 30 is fixed on the hinge fixing plate 20 . The door body 10 is provided with a mounting groove 110 , and one end of the hinge shaft 30 extends into the mounting groove 110 , and the hinge shaft 30 is provided with a threaded through hole 320 passing through it along the axis. The shaft sleeve 40 is located in the installation groove 110 , and the shaft sleeve 40 covers one end of the hinge shaft 30 . The limiting member 60 is arranged in the sleeve 40 and is located between the sleeve 40 and one end of the hinge shaft 30 , the limiting member 60 is provided with a first limiting portion 610 , and the hinge shaft 30 is provided with a second limiting portion 310 , the first limiting portion 610 cooperates with the second limiting portion 310 to limit the movement of the limiting member 60 relative to the hinge shaft 30 in the direction of its axis. The screw rod 50 passes through the threaded through hole 320 , and one end of the screw rod 50 passes through one end of the hinge shaft 30 and abuts against the limiting member 60 .

For example, as shown in the example in FIG. 3 , the hinge fixing plate 20 may be spaced apart from the door body 10 , and the left end of the hinge fixing plate 20 may be fixed on the casing 710 of the refrigerator 700 . A hinge shaft 30 can be fixedly arranged on the hinge fixing plate 20, and the inside of the hinge shaft 30 has a threaded through hole 320 penetrating along the axis direction of the hinge shaft 30 (that is, the up-down direction shown in FIG. 3 ), and the screw rod 50 is threaded through. In the threaded through hole 320. The lower end of the door body 10 is provided with an installation groove 110 with an opening downward. The installation groove 110 may be a cylindrical hole, and a shaft sleeve 40 is embedded in the installation groove 110 . The shaft sleeve 40 covers the upper end of the hinge shaft 30 , and a limiting member 60 is disposed between the shaft sleeve 40 and the hinge shaft 30 . For example, the limiting part 60 can be fixedly connected on the inner top wall of the shaft sleeve 40, that is, no relative movement can occur between the limiting part 60 and the shaft sleeve 40; the limiting part 60 can also be sandwiched between the shaft sleeve 40 and the hinge shaft. 30, and the spacer 60 and the bushing 40 are not fixed, that is, the spacer 60 and the bushing 40 can move relative to each other. The upper end of the limiting member 60 abuts against the inner top wall of the shaft sleeve 40 , and the lower end of the limiting member 60 abuts against the upper end of the screw rod 50 .

As shown in FIG. 5 , the lower end of the limiting member 60 is provided with a first limiting portion 610 , and correspondingly, a second limiting portion matching the first limiting portion 610 is provided on the inner peripheral wall of the hinge shaft 30 310. The first limiter 610 cooperates with the second limiter 310 to limit the movement of the limiter 60 relative to the hinge shaft 30 in its axial direction (ie, the up-down direction shown in FIG. 60 and the hinge shaft 30 are relatively rotated.

It should be noted that, as shown in FIG. 3 , the hinge fixing plate 20 is fixed on the casing 710 of the refrigerator 700, and the hinge shaft 30 is fixedly connected with the hinge fixing plate 20. Therefore, the hinge shaft 30 and the hinge fixing plate 20 are relatively The housing 710 remains stationary all the time. The screw rod 50 is installed in the threaded through hole 320 of the hinge shaft 30, the hinge shaft 30 can be threadedly connected with the screw rod 50, that is to say, the screw rod 50 can rotate relative to the hinge shaft 30, when the screw rod 50 rotates relative to the hinge shaft 30 , the screw 50 will also move relative to the hinge shaft 30 along its axis direction (ie, the up-down direction shown in FIG. 3 ). For example, when the screw rod 50 rotates relative to the hinge shaft 30 (for example, the screw rod 50 rotates clockwise relative to the hinge shaft 30), the screw rod 50 moves downward relative to the hinge shaft 30 along its axis direction (ie, the up-down direction shown in FIG. 3 ). Move; when the screw rod 50 rotates relative to the hinge shaft 30 (for example, the screw rod 50 rotates counterclockwise relative to the hinge shaft 30), the screw rod 50 moves upward relative to the hinge shaft 30 along its axis direction (ie, the up-down direction shown in FIG. 3 ) .

Since the screw rod 50 is movable relative to the hinge shaft 30 in its axial direction (ie, the up-and-down direction shown in FIG. 3 ), the limiting member 60 cooperating with the screw rod 50 can also move along with the movement of the screw rod 50 . It should be noted that, as shown in FIG. 5 , a first limiting portion 610 is provided on the limiting member 60 , and a second limiting portion 310 matching the first limiting portion 610 is provided on the hinge shaft 30 , the limited fit between the first limiting part 610 and the second limiting part 310 can prevent the relative rotation of the limiting part 60 and the hinge shaft 30 along the circumferential direction, and then make the limiting part 60 rotate along the hinge shaft 30 The axial direction (ie, the up and down direction shown in FIG. 5 ) moves. For example, as shown in Figure 3, when the screw rod 50 moves upward, the screw rod 50 can drive the stopper 60 to move upward, and then the stopper 60 can drive the shaft sleeve 40 and the door body 10 to move upward; when the screw rod 50 moves downward , the door body 10 moves downward with the movement of the screw rod 50 under the action of its own gravity.

Thereby, the height adjustment of the door body 10 along the vertical direction can be realized. Therefore, when the door body 10 of the refrigerator 700 is displaced in the vertical direction due to long-term use, or the height of the left and right door bodies 10 of the refrigerator 700 is inconsistent due to the dimensional error generated during the production of the door body 10, you can adjust the height of the refrigerator 700 The door body assembly 100 can conveniently adjust the height of the door body 10 up and down, thereby maintaining the overall appearance of the refrigerator 700.

According to the door body assembly 100 of the refrigerator 700 of the embodiment of the present invention, by rotating the screw rod 50, the screw rod 50 can move in the up and down direction when rotating. The shaft sleeve 40 arranged in the installation groove 110 of the door body 10 is offset. Therefore, when the screw rod 50 moves up and down, it can drive the stopper 60 to move up and down, and then the stopper 60 drives the shaft sleeve 40 and the door body 10 to move up and down, thereby realizing the height adjustment of the door body 10 along the up and down direction. The structure is simple and the operation is convenient, and it effectively overcomes the problem that the height of the left and right doors 10 of the refrigerator 700 is inconsistent and affects the overall aesthetics of the refrigerator 700.

According to an embodiment of the present invention, as shown in FIG. 5 , the first limiting portion 610 is a limiting column 611, and the limiting column 611 extends from the end of the limiting member 60 toward the hinge fixing plate 20, that is, in FIG. 5 As shown, the limiting post 611 protrudes from the lower end of the limiting member 60 and extends downward. The second limiting portion 310 is a limiting groove 311 extending along the axis of the hinge shaft 30. As shown in FIG. The limit groove 311 extending in the up and down direction shown), the limit post 611 is movable along the limit groove 311. It can be understood that, as shown in FIG. 5 , when the limiting column 611 of the limiting member 60 extends into the limiting groove 311 of the hinge shaft 30 , the limiting column 611 can move up and down along the limiting groove 311 , Therefore, the limiting member 60 can move up and down relative to the hinge shaft 30 , and the relative rotation between the limiting member 60 and the hinge shaft 30 can be prevented. Thus, when the screw rod 50 rotates, the vertical movement of the screw rod 50 relative to the hinge shaft 30 can drive the stopper 60 to move up and down, and then drive the shaft sleeve 40 and the door body 10 to move up and down. Moreover, it can effectively prevent the height of the door body 10 from changing due to the limit member 60 being driven to rotate relative to the hinge shaft 30 when the door body 10 rotates.

Further, there are a plurality of limiting grooves 311 , and the plurality of limiting grooves 311 are spaced apart along the circumferential direction of the hinge shaft 30 . There are a plurality of limiting columns 611 , and the plurality of limiting columns 611 correspond to the plurality of limiting grooves 311 one by one. As shown in FIG. 5 , two limiting grooves 311 extending along the axial direction of the hinge shaft 30 (that is, the up-and-down direction shown in FIG. 5 ) are arranged symmetrically at intervals on the inner peripheral wall of the hinge shaft 30 . The lower end of the limiting member 60 is symmetrically provided with two limiting posts 611 extending downward. The two limiting posts 611 can correspondingly extend into the limiting groove 311 , so that the limiting member 60 can move up and down relative to the hinge shaft 30 and prevent the limiting member 60 from rotating relative to the hinge shaft 30 . Of course, a plurality of limiting grooves 311 can also be provided. Correspondingly, a plurality of limiting columns 611 are provided and correspond to the limiting grooves 311 one by one.

In some embodiments of the present invention, the cross section of the limiting post 611 may be circular, elliptical or polygonal. In other words, the limiting post 611 may be configured in a cylindrical shape, an elliptical cylindrical shape or other polyhedral shapes. For example, as shown in the example in FIG. 5 , two spacer posts 611 extending downward are arranged symmetrically at intervals at the lower end of the stopper 60 . Can be set with chamfers. Setting the limiting column 611 as a rectangular parallelepiped column facilitates the processing and manufacturing of the limiting column 611 , thereby reducing the processing cost of the limiting member 60 .

According to an embodiment of the present invention, as shown in FIG. 3 , a receiving groove 620 may be provided on an end surface of the limiting member 60 facing the screw rod 50 . That is to say, the lower end of the limiting member 60 may be provided with a receiving groove 620 , which may be a circular hole, and the upper end of the screw rod 50 may extend into the receiving groove 620 . Therefore, when assembling the door body assembly 100 of the refrigerator 700, the receiving groove 620 can play a role of guiding and positioning, facilitating the assembly and fixing between the screw rod 50 and the limiting member 60, and the receiving groove 620 is set on the upper end of the screw rod 50 , when the rotation of the screw rod 50 produces a displacement in the up and down direction, it can more stably drive the limiting member 60 to move in the up and down direction.

According to an embodiment of the present invention, a buffer curved surface 410 may be provided on the wall surface of the sleeve 40 opposite to one end of the screw rod 50 . For example, as shown in the example in FIG. 3 , a buffer curved surface 410 is provided at a position opposite to the screw rod 50 on the inner top wall of the shaft sleeve 40 , and the buffer curved surface 410 is formed as a downward protrusion, and the lower end of the buffer curved surface 410 is in contact with the stopper. The upper end of 60 offsets. Thus, when the screw rod 50 rotates in the threaded through hole 320, for example, when the screw rod 50 rotates counterclockwise, the screw rod 50 moves upward relative to the hinge shaft 30, and the upper end of the screw rod 50 is against the stopper 60, so the screw rod 50 can Drive the stopper 60 to move upward. The upper part of the limiting member 60 is offset against the buffer curved surface 410. When the limiting member 60 moves upward, the limiting member 60 presses the buffer curved surface 410 upwards and drives the bushing 40 and the door body 10 to move upward relative to the hinge shaft 30. The buffer curved surface 410 provided on the shaft sleeve 40 can absorb the upward pressing force of the buffer limiting member 60 on the shaft sleeve 40 and prevent the upward pressing force of the limiting member 60 from causing fatigue damage to the shaft sleeve 40 and the door body 10 .

In some embodiments of the present invention, there may be a flange 420 on the periphery of the shaft sleeve 40 close to the hinge fixing plate 20 , and the flange 420 is located outside the installation groove 110 . For example, as shown in the example in FIG. 3 , an annular flange 420 is arranged at the lower end of the shaft sleeve 40 , and the upper end of the flange 420 is against the lower end of the door body 10 , and the shaft sleeve 40 can be welded or bonded to the door through the annular flange 420 . On the body 10 , in order to enhance the stability of fixing between the shaft sleeve 40 and the door body 10 , the shaft sleeve 40 can also be embedded in the installation groove 110 of the door body 10 . When the screw rod 50 rotates upwards to drive the stopper 60 to move upward, the stopper 60 produces an upward extrusion force on the bushing 40, and the annular flange 420 at the lower end of the bushing 40 can disperse the extrusion force, so that the bushing 40 is opposite to the door body. The upward thrust of 10 is more uniform, so as to drive the door body 10 to move upwards.

According to an embodiment of the present invention, an adjustment groove 510 is provided on the end surface of the other end of the screw rod 50, and the adjustment groove 510 is in the shape of "+" or "-". For example, as shown in the example in Fig. 6, an adjustment groove 510 is provided at the lower end of the screw rod 50 (in the up-and-down direction as shown in Fig. 6 ), and the shape of the adjustment groove 510 is "+". In an example, the adjustment groove 510 may also be set in a "-" shape. Therefore, the screw rod 50 can be twisted from the lower end of the screw rod 50 by using a cross-shaped or flat-shaped screwdriver to realize the up and down movement of the screw rod 50, thereby driving the stopper 60 to move up and down, and then the stopper 60 drives the shaft sleeve 40 and the door body 10 moves up and down to adjust the height of the door body 10, which is easy to operate and flexible to adjust.

According to an embodiment of the present invention, the other end of the hinge shaft 30 has an annular installation groove 330 , and the hinge fixing plate 20 is clamped in the annular installation groove 330 . For example, as shown in the example in Fig. 3, the lower end of the hinge shaft 30 may be provided with an annular mounting groove 330, that is, at the lower end of the hinge shaft 30, there is an annular mounting groove 330 whose radial radius is smaller than the radial radius of the remaining positions. The height of the installation groove 330 along the up-down direction (the up-down direction as shown in FIG. 3 ) is equal to the thickness at the position where the hinge fixing plate 20 is assembled with the hinge shaft 30 (that is, the thickness of the hinge fixing plate 20 along the up-down direction shown in FIG. 3 ) is equal. , so that the hinge shaft 30 can be stably fixed on the hinge fixing plate 20 to prevent relative movement between the hinge shaft 30 and the hinge fixing plate 20 . It should be understood that the hinge fixing plate 20 may include two pieces divided along the axial direction of the hinge shaft 30, and the fitting hole of the hinge shaft 30 is formed at the joint of the two hinge fixing plates 20, which is adapted to the annular mounting groove 330, thereby Fix the hinge fixing plate 20 in the annular installation groove 330 of the hinge shaft 30 .

In some other embodiments of the present invention, the hinge shaft 30 can also be fixedly assembled on the hinge fixing plate 20 through riveted connection, thereby, the stability of the connection between the hinge shaft 30 and the hinge fixing plate 20 can be enhanced, preventing the hinge shaft from Relative movement occurs between 30 and hinge fixing plate 20. Of course, the hinge shaft 30 and the hinge fixing plate 20 can also be fixedly assembled by welding or other connection methods.

The door assembly 100 of the refrigerator 700 according to the present invention will be described in detail in a specific embodiment below with reference to FIGS. 1-6 . It should be understood that the following description is only an illustration rather than a specific limitation to the present invention.

As shown in FIGS. 1-6 , the door body assembly 100 of the refrigerator 700 includes: a door body 10 , a hinge fixing plate 20 , a hinge shaft 30 , a shaft sleeve 40 , a limiting member 60 and a screw rod 50 .

Wherein, as shown in FIG. 1 , two door bodies 10 are arranged above the refrigerator 700 along the left-right direction (the left-right direction as shown in FIG. 1 ). A hinge fixing plate 20 is arranged at intervals below the door body 10 , and the hinge fixing plate 20 is fixedly connected with the casing 710 of the refrigerator 700 . As shown in FIG. 3 , a hinge shaft 30 is fixed on the hinge fixing plate 20 . The lower end of the hinge shaft 30 is provided with an annular installation groove 330 , and the hinge fixing plate 20 is clamped in the annular installation groove 330 . The inside of the hinge shaft 30 is provided with a threaded through hole 320 penetrating along the axial direction of the hinge shaft 30 (ie, the up-down direction shown in FIG. 3 ). The screw rod 50 is screwed into the threaded through hole 320, and the lower end of the screw rod 50 is provided with a "+" shaped adjustment groove 510 (as shown in FIG. 6 ).

As shown in FIG. 3 , a cylindrical installation groove 110 is provided at the lower end of the door body 10 , and a shaft sleeve 40 is embedded in the installation groove 110 . The lower end of the shaft sleeve 40 is provided with an annular flange 420 , the shaft sleeve 40 is set above the hinge shaft 30 , and the inner top wall of the shaft sleeve 40 is provided with a buffer curved surface 410 opposite to the hinge shaft 30 . A limiting member 60 is arranged between the buffer curved surface 410 and the screw rod 50, the upper end of the limiting member 60 is against the buffer curved surface 410, the lower end of the limiting member 60 is provided with a receiving groove 620, and the upper end of the screw rod 50 extends into the receiving groove 620 Offset against the limit piece 60.

As shown in FIG. 5 , two spacer posts 611 extending downward are arranged symmetrically at intervals at the lower end of the stop member 60 . Two limiting grooves 311 are arranged symmetrically in the vertical direction shown in FIG. 5 . The limit post 611 is a cuboid cylinder, and the limit post 611 cooperates with the limit groove 311 to limit the movement of the limit member 60 in the up and down direction and prevent the relative rotation between the limit member 60 and the hinge shaft 30 .

It should be noted that, as shown in FIG. 3 , the hinge fixing plate 20 is fixed on the casing 710 of the refrigerator 700, and the hinge shaft 30 is fixedly connected with the hinge fixing plate 20. Therefore, the hinge shaft 30 and the hinge fixing plate 20 are relatively The housing 710 remains stationary all the time. The screw rod 50 is installed in the threaded through hole 320 of the hinge shaft 30, the hinge shaft 30 can be threadedly connected with the screw rod 50, that is to say, the screw rod 50 can rotate relative to the hinge shaft 30, when the screw rod 50 rotates relative to the hinge shaft 30 , the screw rod 50 will also move relative to the hinge shaft 30 along its axis direction. For example, when the screw rod 50 rotates relative to the hinge shaft 30 (for example, the screw rod 50 rotates clockwise relative to the hinge shaft 30), the screw rod 50 moves downward relative to the hinge shaft 30 along its axis direction (ie, the up-down direction shown in FIG. 3 ).
