The end away from the user is the second end B 232 . The first end A 131 is provided with a fixed shaft 110 ; the second end B232 is provided with a hook portion 210 , and the hook portion 210 has a limiting groove 212 . The second slide rail 200 has a first position, a second position and a third position relative to the first slide rail 100; when the second slide rail 200 is in the first position, the fixed shaft 110 is separated from the hook portion 210, and the second The end B 232 is closer to the second end A 132 than the first end B 132, refer to Fig. 1 and Fig. 2; when the second slide rail 200 is in the second position, the fixed shaft 110 slides into the hook portion 210, refer to Fig. 3. When the second slide rail 200 is in the third position, the fixed shaft 110 is engaged in the limiting groove 212 and the second slide rail 200 is inclined relative to the first slide rail 100 , referring to FIG. 4 .

In FIG. 1 to FIG. 4 , in order to clearly express the state changes of the entire slide rail mechanism when the second slide rail 200 is in each position, the second slide rail 200 is structurally expressed from two perspectives in each position state. Figure 1(a), Figure 2(a), Figure 3(a) and Figure 4(a) are axonometric drawings, Figure 1(b), Figure 2(b), Figure 3(b) and Figure 4(b) ) is a front view, and in order to clearly express the cooperation relationship between the fixed shaft 110, the hook part 210 and the limit groove 212, Fig. 1(b), Fig. 2(b), Fig. 3(b) and Fig. 4(b ) for structural expression in the form of perspective.

When the second slide rail 200 is at the first position, the second slide rail 200 can reciprocally slide along the first slide rail 100 . FIG. 1 is a schematic diagram of the structure of the second slide rail 200 when it has not been pulled out relative to the first slide rail 100. B 232 coincides. FIG. 2 is a schematic diagram of the structure of the second slide rail 200 after being pulled out for a certain distance relative to the first slide rail 100. At this time, as the second slide rail 200 is pulled outward, the second end B 232 gradually moves closer to the first slide rail 100. One end A 131 moves in the direction.

When the second slide rail 200 is drawn to the second position, referring to FIG. 3 and FIG. 5 , the fixed shaft 110 slides into the hook portion 210 , and the second slide rail 200 cannot continue to slide forward.

Press down the second slide rail 200, the second slide rail 200 will be inclined downward relative to the first slide rail 100, referring to Figure 4 and Figure 7, at this time the hook part 210 will rotate clockwise around the fixed shaft 110, The fixed shaft 110 snaps into the limiting slot 212 along the way, so that the second slide rail 200 will not fall while tilting downward. Moreover, the second sliding rail 200 will further make the engagement between the fixed shaft 110 and the limiting groove 212 more reliable and not easy to fall off under the action of gravity.

As a preferred embodiment, the hook portion 210 includes a main body 211, and a limiting groove 212 is formed on the main body 211. The opening 213 of the limiting groove 212 faces upwards, so that when the second sliding rail 200 tilts downward, the fixed shaft 110 can It is smoothly snapped into the limiting slot 212.

Further preferably, referring to FIG. 5 and FIG. 7 , the main body 211 is provided with an upper stop portion 214 , the upper stop portion 214 is a baffle structure formed integrally with the main body 211 , and the upper stop portion 214 is opposite to the limit groove 212 . The upper stop portion 214 plays a guiding role to facilitate the fixed shaft 110 to slide into the hook portion 210 . Simultaneously, when the second slide rail 200 is tilting downward and has not been snapped into the movement process of the limiting groove 212, the upper stop portion 214 can also prevent the fixed shaft 110 from detaching from the hook portion 210, making the whole slide rail structure more stable. reliable.

Of course, in other embodiments, the hook portion 210 may not be provided with the upper stop portion 214 , and the tilting movement of the second slide rail 200 can also be realized.

Referring to FIG. 9 , the second sliding rail 200 includes a side plate B 240 and an upper plate B 250 disposed on the upper side of the side plate B 240 , and the hook portion 210 is disposed on the side plate B240 . When the second slide rail 200 is at the first position, the upper board B 240 is located inside the upper board A 250 , and the side board B 240 is opposite to the side board A 140 . That is, the first slide rail 100 and the second slide rail 200 are snap-fit structures, the second slide rail 200 is located inside the first slide rail 100, and a cavity is formed between the two to facilitate the fixing of the shaft 110 and the hook. The coordinated movement between the portion 210 and the limiting groove 212 also helps to reduce the thickness and size of the overall slide rail mechanism and reduce the occupied space.

As a preferred embodiment, the first slide rail 100 also includes a front side plate A 170 located at the first end A 131 and a rear side plate A 180 located at the second end A 132; A front side panel B 260 at the end B 231 and a rear side panel B 270 at the second end B 232 . The front side plate A 170, the rear side plate A 180, the front side plate B 260 and the rear side plate B 270 play a shielding role on the internal space defined by the first slide rail 100 and the second slide rail 200, so that the entire slide rail Institutions are more aesthetically pleasing.

As a preferred embodiment, the relative sliding between the first sliding rail 100 and the second sliding rail 200 is realized by a roller structure, which has low friction and low noise. Specifically, the free end of the fixed shaft 110 is provided with a first roller 120 , and the first roller 120 is in rolling contact with the inner side of the second slide rail 200 .

When the first slide rail 100 and the second slide rail 200 slide relative to each other, both the first roller 120 and the second roller 220 will rotate.

As a preferred embodiment, referring to Fig. 1(b), the first roller 120 is rollingly attached to the upper inner surface of the second slide rail 200, that is, the first roller 120 is rolled and attached to the upper plate B 250; the second The rollers 220 are in rolling contact with the lower inner surface of the first sliding rail 100 , that is, the second rollers 220 are in rolling contact with the lower plate A 160 . When the first slide rail 100 and the second slide rail 200 slide relative to each other, the first roller 120 will roll along the upper board B 250 , and the second roller 220 will roll along the lower board A 160 . It can be seen from Fig. 1(b) that the first rollers 120 and the second rollers 200 are relatively staggered, so that when the first slide rail 100 and the second slide rail 200 slide relative to each other, there will be no up-down direction between them. The shaking on the top makes the whole slide rail mechanism more stable.

Further, there is a certain gap between the side board B 240 and the lower board A 160, and there is also a certain gap between the upper board A 150 and the upper board B 250, so that when the first slide rail 100 and the second slide rail 200 During relative sliding, it is only realized by rolling between the first roller 120 and the upper plate B 250, the second roller 220 and the lower plate A 160, and the rest of the first slide rail 100 and the second slide rail 200 are not in contact. It is beneficial to reduce friction and reduce noise.

As a preferred embodiment, when the second sliding rail 200 is switched between the second position and the third position, the first roller 120 and the second roller 220 roll and fit together. Specifically, when the second slide rail 200 is located at the second position, referring to FIG. 5 , the first roller 120 and the second roller 220 are attached. When the second slide rail 200 changes from the second position to the third position, press down on the second slide rail 200, and the second roller 220 will roll clockwise along the first roller 120, referring to FIG. 7, so that the second slide rail 200 The downward tilt movement is smoother and smoother. Similarly, when the second slide rail 200 changes from the third position to the second position, the second slide rail 200 is lifted up, and the second roller 220 will roll counterclockwise along the first roller 120 until it contacts the lower board A 160 .

As a preferred embodiment, the upper plate A 150 has a notch 151 located at the first end A 131 . When the second slide rail 200 is in the third position, referring to FIG. 6 , the second end B 232 protrudes from the notch 151 , and the notch 151 makes way for the second end B 232 to facilitate the second slide rail 200 to tilt down.
