Description

  The present invention relates to a cabinet damping structure.

As a technique for improving the rigidity of the cabinet and avoiding damage to the cabinet against the shaking of the earthquake (a so-called technique for improving the earthquake resistance function), a structure (Patent Document 1) in which bracing is made in the opening of the cabinet body is disclosed. ing. This structure is an effective means for improving the seismic performance of the cabinet body, but it is necessary to remove the braces when installing the equipment or during maintenance. Also, if you forget to return the bracing to its original position before closing the door, you will not be able to demonstrate earthquake resistance.
On the other hand, a structure (Patent Document 2) is disclosed in which a protrusion from the door is inserted into a hole of the frame in order to cause the cabinet door to function as a bracing. Since this structure does not have braces, there is no need to remove the braces during maintenance or to forget to return the braces to their original positions before tightening the doors. If a load is applied, the hinges, etc. may be damaged. As a result, when large aftershocks occur repeatedly, there is a risk that sufficient performance cannot be exhibited.

  In addition, the techniques of Patent Documents 1 and 2 both prevent damage to the cabinet body against vibrations, and the effect of absorbing the vibrations and suppressing the shaking of the cabinet and the door itself (so-called vibration control function). Cannot be expected.

  Preferred embodiments of the present invention are shown below. In the description of the embodiment, damage means that the cabinet does not return to its original shape due to vibration, and deformation refers to a case where the shape is temporarily distorted, and when the vibration disappears, it returns to its original shape. Say.

  As shown in FIG. 1, the cabinet body 1 according to the first embodiment of the present invention includes an outer cabinet 30 including a support frame 31, a horizontal frame 32, and a depth frame 33, and an inner cabinet 40 including a bottom plate 41 and a mounting rail 42. A double structure consisting of The lower end of the mount rail 42 is fixed to the bottom plate 41, and the upper end is fixed to the depth frame 33 of the outer cabinet 30. The bottom plate 41 of the inner cabinet 40 and the depth frame 33 of the outer cabinet 30 are supported by a vibration control member (not shown) in which viscoelastic bodies are laminated, and the inner cabinet 40 is shaken and viscoelastically caused by earthquake vibration. The body is deformed to absorb vibration energy and prevent the outer cabinet 30 and the inner cabinet 40 from being damaged. The cabinet body 1 may not have the double structure, but may have a monocoque structure in which the cabinet body 1 is formed by bending a plate.

  As shown in FIG. 2, the cabinet body 1 includes a door 2 as a closing member that closes the opening 34 on the front surface and the back surface so as to be freely opened and closed. The door 2 is locked to the cabinet body 1 by a clamp handle lock 17 and a rod bar 11 which will be described later. A side plate 13 is provided as a member for closing the opening 35 on the side surface, and is fixed to the cabinet body 1 with a fixing screw 14, a latch lock 15 or the like as a fastening fixing portion.

  The door 2 is formed by bending a plate material, and has a vent hole formed by punching a punching metal at the center. The ventilation hole is not particularly limited to those formed by punching a punching metal, and may be one in which another member is fitted and fixed. Further, reinforcing members 16 are provided on the back side of the door 2 in the vertical direction along both sides of the punching metal to prevent the door 2 from being bent in the vertical direction. The door 2 is made only of a bent plate material and does not have to have a punching metal.

  As shown in FIGS. 2 and 3, the vibration control member 3 is provided at the upper and lower ends of one reinforcing member 16 of the door 2 and at the peripheral edge of the back surface.

  FIG. 4 is a diagram illustrating the state in which the vibration control member 3 is coupled to the cabinet body 1 with the door omitted. The damping member 3 includes a fitting plate 6 having a groove portion 5 as a fitting portion that fits in a horizontal direction with a convex fitting portion 4 provided at the periphery of the opening of the cabinet body 1 when the door 2 is closed. The mounting plate 8 includes a mounting portion 7 for the door 2 and a viscoelastic body 9 mounted between the fitting plate 6 and the mounting plate 8 as shown in FIG. It is preferable that the fitted portion 4 has a structure in which it is integrally formed with a hollow frame member constituting the cabinet body 1. As will be described later, the viscoelastic body 9 has a function of preventing the outer cabinet 30 from being damaged by effectively absorbing the energy generated when the cabinet body 1 and the door 2 are deformed by vibration and replacing the heat energy. Further, since the vibration control member 3 is disposed at the peripheral edge of the back surface of the door 2, even if a vent hole made of punching metal or the like is formed, these vent holes are blocked by the vibration control member 3. Therefore, the ventilation environment in the cabinet can be maintained well.

  The fitting structure between the cabinet body 1 and the fitting plate 6 is not particularly limited. For example, a protrusion formed on the fitting plate 6 may be fitted into a fitting hole formed on the cabinet body 1. In this embodiment, the mounting plate 8 is attached to the door 2, but the mounting plate 8 is attached to the peripheral edge of the opening of the cabinet body 1, and the groove portion 5 of the fitting plate 6 is directed to the door side and formed on the door 2. It can also be set as the structure fitted with the convex to-be-fitted part. Furthermore, in this embodiment, although the groove part 5 is formed in the horizontal direction, if the groove part 5 is also formed in the up-down direction in addition to this, the cabinet body 1 and the door 2 are horizontally aligned with the vibration. It is possible to bond more firmly in the direction. Further, the mounting plate 8 may be attached to the opening peripheral edge of the cabinet body 1, and a fitting portion is formed on the door at a position corresponding to this, and the groove portion 5 of the fitting plate 6 is fitted. Also good.

  In general, viscoelastic bodies have high rigidity at low temperatures and low rigidity at high temperatures. In this embodiment, since it is used for a vibration control cabinet that accommodates electronic equipment or the like, for example, it is relatively in terms of rigidity and damping performance in a normal room temperature range, for example, a temperature range of about 0 ° C. to 50 ° C. It is desirable to use a viscoelastic body having stable properties.

  As shown in FIG. 6, the back surface of the door 2 of the present embodiment is provided with a clamp handle lock 17 as a chain means and a rod bar 11 interlocking with the clamp handle lock 17. When the door 2 is closed, the clamp handle The door 2 and the cabinet body 1 are coupled by locking the locking piece of the lock 17 and the tip of the rod rod 11 to the locking portion 12 formed at the periphery of the opening 24 of the cabinet body 1. For this reason, even when an earthquake occurs, the door 2 does not open, and the convex side 4 provided on the periphery of the opening and the groove 5 of the vibration control member 3 are kept in a fitted state at an appropriate position, and will be described later. The seismic function can be demonstrated.

  In the present embodiment, as shown in FIG. 2, the damping member 3 is a peripheral edge of the back surface of the door 2 that serves as a mating surface between the cabinet body 1 and the door 2, on the opposite side that is different from the side on which the hinge 10 is formed. It is arranged at two places on the upper and lower ends. Although the hinge 10 is provided at three locations in the vertical direction, the description will be made assuming that the hinges are provided at two locations on the top and bottom in order to simplify the explanation of the following vibration control function.

  FIG. 7 shows a state in which the cabinet body 1 is deformed due to vibration with the door 2 closed on the cabinet body 1. The door 2 exhibits a muscular function with a pair of hinges 10a and 10b positioned substantially diagonally to the vibration control members 3a and 3b. When the cabinet body 1 is deformed, the bracing function is pulled back to the original state by the mounting plate 8, the viscoelastic body 9, and the fitting plate 6 of the vibration control member 3 from the hinge 10 through the surface of the door 2. Refers to function. A broken line in FIG. 7 is a bracing line showing a state in which the bracing function acts on the surface of the door 2. When the cabinet body 1 is deformed to the right side of the paper surface, the hinges 10a and 10b are physically integrated with the cabinet body 1 and the door 2, so that the positional relationship does not change, but the vibration control members 3a and 3b side is the cabinet. A shift occurs in the positional relationship between the main body 1 and the door 2. The viscoelastic body 9 acts to return the shift caused by the deformation of the cabinet body 1 to its original state. In addition, in order to simplify description here, when the cabinet body 1 is deformed, only the bracing function generated between the vibration control member and the hinge having a diagonal relationship with a large deviation has been described. The muscular function occurs between all the vibration control members and the hinges.

  Thereby, the cabinet main body 1 can prevent the outer cabinet 30 from being damaged by the vibration due to the bracing function of the door 2. Moreover, since the positional relationship between the door 2 and the cabinet body 1 changes according to the vibration by the vibration control member 3, the door itself can be prevented from being damaged.

  Here, since the vibration control member 3 includes the viscoelastic body 9, the energy that causes the shaking of the cabinet body 1 is effectively absorbed instead of the heat energy to suppress the damage of the outer cabinet 30.

  The location of the damping member 3 may be different from the side where the hinge 10 is formed at the peripheral edge of the back surface of the door 2, and in addition to this embodiment, as shown in FIG. Can do. For example, in FIG. 8A, the position of the vibration control member 3 is positioned at the middle portion in the vertical direction. Since the clamp handle lock 17 is disposed in the vicinity of the middle part of the door 2, the force for coupling the door 2 and the cabinet body 1 is strong, and even if the cabinet does not have the rod rod 11, The effect can be demonstrated. In (b), since the number of the damping members 3 is one, the cost can be reduced. (C) is provided with a vibration control member 3 in the vicinity of the locking portion 12 where the clamp handle lock 17 and the rod bar 11 engage with the cabinet body 1, and the vibration control is performed at a location where the force for connecting the door 2 and the cabinet body 1 is strong. By arranging the member 3, the function can be effectively exhibited. Moreover, the cabinet 1 can be effectively prevented from being damaged by exerting the bracing function even in the intermediate portion. In (d), since the damping members 3 are placed on the upper and lower sides in addition to the corners, the muscular line is formed even at a short distance, and the function is effectively exhibited. In addition, although it is preferable to provide the damping member 3 in the position of an up-and-down object, the position of the damping member 3 does not necessarily need to be arrange | positioned symmetrically up and down and right and left like (e). Further, when the damping member 3 is arranged at the corner as shown in (f), the fitting plate 6 and the mounting plate 8 constituting the damping member 3 are formed in an L-shape, and a plurality of the plates are interposed between the plates. The viscoelastic body 9 can be attached.

  In the above embodiment, the example in which the vibration control member 3 is disposed on the back surface of the door 2 has been described. However, as in the second embodiment illustrated in FIG. 9, the vibration control member 3 has a side opening 35. It can also be arranged on the back surface of the side plate 13 which is a closing member that is detachably mounted on the side plate.

  The side plate 13 is provided with a pair of reinforcing members 18 in the vertical direction like the door 2, and the vibration control member 3 similar to that of the first embodiment is attached to the upper end of the reinforcing member 18. Further, a convex side portion 19 is provided on the upper part of the side surface of the cabinet body 1 as a fitted portion corresponding to the groove portion 5 which is a fitting portion provided in the vibration control member 3. Further, a latch lock 15 is provided in the vicinity of the side plate 13 where the vibration control member 3 is fixed, and the side plate 13 is fixed to the cabinet body 1. In addition, the lower side of the opposite side plate 13 is fixed to the cabinet body 1 with a fixing screw 14 which is a tightening fixing portion. The latch lock 15 facilitates attachment / detachment of the side plate 13 to / from the cabinet body 1 and prevents the side plate 13 from being detached from the cabinet body 1 due to vibrations. The state of being fitted to is maintained.

  Thereby, even if the cabinet main body 1 and the side plate 13 are deformed by vibration, the vibration control function equivalent to that of the first embodiment can be exhibited. That is, since the fixing screw 14 physically integrates the cabinet main body 1 and the side plate 13, the positional relationship thereof does not change, but the vibration damping members 3 a and 3 b are in the positional relationship between the cabinet main body 1 and the side plate 13. Deviation occurs. The viscoelastic body 9 acts to return the shift caused by the deformation of the cabinet body 1 to its original state. Moreover, the same effect as 1st Embodiment can be show | played by arrange | positioning the damping member 3 in the edge | side where the fixing screw 14 of the side plate was formed in the back surface peripheral part of the side plate 13.
