Technical Field
[0001] This utility model relates to the field of distribution box technology, specifically a wall-mounted distribution box. Background Technology
[0002] Distribution boxes are key devices for distributing electrical energy in power systems. Their outer shells are mostly made of metal or insulating materials, which are dustproof and moisture-proof and adaptable to different environments. Inside the box, there are usually core components such as circuit breakers and residual current devices. According to their uses, there are household distribution boxes for residential buildings and power distribution boxes for industrial sites. The specifications are determined according to the electrical load. There are various installation methods for distribution boxes, usually including floor-mounted or wall-mounted. Among them, wall-mounted distribution boxes are widely used in civil scenarios due to their flexible installation and lack of ground space. In addition, compared with floor-mounted installation, which may be affected by ground water seepage and debris accumulation, wall-mounted distribution boxes can more effectively stay away from ground moisture and dust, reducing the probability of short circuit failure of internal components due to moisture. However, if the wall-mounted distribution box is tightened too much during installation, the mounting screws are prone to falling off when subjected to external force. If the installation is too loose, the back of the box cannot fit properly against the wall, resulting in insufficient support and friction. When subjected to impact, the box is prone to displacement or even falling. Therefore, a wall-mounted distribution box is proposed to address the above problems. Utility Model Content
[0003] The purpose of this utility model is to provide a wall-mounted distribution box to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A wall-mounted distribution box includes a wall and a distribution cabinet. A positioning component is fixedly connected to one side of the wall by screws. A support component is slidably installed inside the positioning component. The distribution cabinet is welded to one end of the support component. An elastic arc sheet is welded to the outside of the distribution cabinet. A rubber strip is adhered to the side of the elastic arc sheet near the distribution cabinet. The positioning component includes a locking rod. A sliding groove and a strip groove are formed inside the locking rod. A clamping block is slidably disposed inside the sliding groove. A compression spring is fixedly connected to one side of the clamping block. A screw is fixedly connected to one side of the clamping block. A moving block is slidably disposed inside the sliding groove. Two locking blocks are fixedly connected to the upper and lower ends of the moving block respectively. A nut is threadedly connected to the outside of the screw.
[0005] As a further optimization of this utility model, the support component includes a sleeve, an insert post is inserted into the inner side of the sleeve, a connecting spring is fixedly connected to the outer side of the insert post, and one end of the connecting spring is fixedly connected to the sleeve.
[0006] As a further optimization of this utility model, the projection of the sleeve in the vertical direction is "I" shaped, the central axis of the insertion post and the central axis of the sleeve are on the same straight line, and two sets of connecting springs are provided, with multiple connecting springs in each set, and the multiple connecting springs are distributed in a circular array.
[0007] As a further optimization of this utility model, the inner side of the sliding groove is in close contact with the outer side of the sleeve, the side of the clamping block away from the compression spring is arc-shaped, and the arc-shaped side of the clamping block is in contact with the outer side of the sleeve.
[0008] As a further optimization of this utility model, the compression spring is sleeved on the outside of the screw, and the central axis of the compression spring and the central axis of the screw are on the same straight line. One end of the compression spring is fixedly connected to a locking block.
[0009] As a further optimization of this utility model, the following features are provided: two grooves are provided, the positions of the two grooves correspond one-to-one with the positions of the locking blocks, the outer side of the locking blocks is in close contact with the inner side of the grooves, one side of the moving block is arc-shaped, and the arc-shaped side of the moving block abuts against the elastic arc sheet.
[0010] As a further optimization of this utility model, the following features are provided: the thread length on the outer side of the screw is half of its own length; the screw passes through the moving block; a gap is provided between the outer side of the screw and the inner side of the moving block; and the side of the moving block away from the compression spring is in contact with the nut.
[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a dynamic clamping and buffering mechanism is created through the synergistic effect of the positioning component, the support component, and the elastic arc sheet. The clamping block fits tightly with the sleeve under the action of the compression spring, and combined with the nut limit, it can fully fit the box with the wall. When the distribution box is subjected to external force, the plug buffers the impact force through the connecting spring to avoid rigid deformation of the box. The clamping block transmits the force to push the moving block, so that the elastic arc sheet and rubber strip further clamp the box, reducing displacement or falling caused by external force.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-6 This utility model provides a technical solution: A wall-mounted distribution box includes a wall 1 and a distribution cabinet 4. A positioning component 2 is fixedly connected to one side of the wall 1 by screws. A support component 3 is slidably installed inside the positioning component 2. The distribution cabinet 4 is welded to one end of the support component 3. An elastic arc sheet 5 is welded to the outside of the distribution cabinet 4. A rubber strip 6 is glued to the side of the elastic arc sheet 5 near the distribution cabinet 4. The positioning component 2 includes a locking rod 21. A sliding groove 22 and a strip groove 23 are opened inside the locking rod 21. A clamping block 24 is slidably arranged inside the sliding groove 22. A compression spring 25 is fixedly connected to one side of the clamping block 24. A screw 26 is fixedly connected to one side of the clamping block 24. A moving block 27 is slidably arranged inside the sliding groove 22. Two locking blocks 28 are fixedly connected to the upper and lower ends of the moving block 27 respectively. A nut 29 is threadedly connected to the outside of the screw 26.
[0017] As a further implementation of this solution, the support component 3 includes a sleeve 31, with a plug 32 inserted inside the sleeve 31 and a connecting spring 33 fixedly connected to the outside of the plug 32. One end of the connecting spring 33 is fixedly connected to the sleeve 31. The projection of the sleeve 31 in the vertical direction is "I" shaped. The central axis of the plug 32 and the central axis of the sleeve 31 are on the same straight line. There are two sets of connecting springs 33, and each set of connecting springs 33 has multiple springs. The multiple connecting springs 33 are arranged in a circular array. The shape of the sleeve 31 makes it difficult for it to fall out when it is stuck in the sliding groove 22, thereby achieving a positioning effect. The design of the plug 32 and the sleeve 31 being coaxial and connected to each other by multiple connecting springs 33 allows the plug 32 to make a certain displacement in the sleeve 31. At the same time, the connecting springs 33 can absorb and buffer the impact and vibration of the plug 32 during operation, preventing the distribution cabinet 4 from deforming due to uneven force when it shakes because of the rigid connection between it and the plug 32. As a further implementation of this solution, the inner side of the sliding groove 22 is in close contact with the outer side of the sleeve 31, and the side of the clamping block 24 away from the compression spring 25 is arc-shaped. The arc-shaped side of the clamping block 24 is in close contact with the outer side of the sleeve 31. Under the pushing force of the compression spring 25, the arc-shaped clamping block 24 is in close contact with the outer side of the sleeve 31, which evenly distributes the clamping force and avoids stress concentration. As a further implementation of this solution, the compression spring 25 is sleeved on the outside of the screw 26, and the central axis of the compression spring 25 and the central axis of the screw 26 are on the same straight line. One end of the compression spring 25 is fixedly connected to the locking block 28. The compression spring 25 and the screw 26 are coaxial, and the design of the compression spring 25 being sleeved on the outside of the screw 26 makes the screw 26 guide the extension and retraction of the compression spring 25. The locking block 28 is fixedly connected to one end of the compression spring 25, so that when the clamping block 24 moves, the locking block 28 restricts the compression spring 25 and provides a buffer. As a further implementation of this solution, two grooves 23 are provided, and the positions of the two grooves 23 correspond one-to-one with the positions of the locking blocks 28. The outer side of the locking blocks 28 is in close contact with the inner side of the grooves 23. One side of the moving block 27 is arc-shaped, and the arc-shaped side of the moving block 27 abuts against the elastic arc plate 5. The grooves 23 restrict the movement path of the locking blocks 28, thereby ensuring that the moving block 27 can slide stably in the sliding groove 22. The design of the arc-shaped side of the moving block 27 abutting against the elastic arc plate 5 means that the movement of the moving block 27 needs to overcome the elastic force when the elastic arc plate 5 deforms, so that the movement of the moving block 27 is buffered. As a further implementation of this solution, the thread length on the outer side of the screw 26 is half its own length. The screw 26 passes through the moving block 27, and there is a gap between the outer side of the screw 26 and the inner side of the moving block 27. The side of the moving block 27 away from the compression spring 25 is in contact with the nut 29. The design that the thread length on the outer side of the screw 26 is half its own length can prevent the nut 29 from continuing to move axially in the unthreaded area, so that the nut 29 squeezes the moving block 27, causing the compression spring 25 to be compressed too much. The clamping block 24 fixed at one end of the compression spring 25 will not be in contact with the outer side of the sleeve 31.
[0018] Workflow: During installation, the four positioning components 2 are fixed to the wall 1 with screws according to the predetermined positions. Then, the distribution cabinet 4 is moved, causing the welded and fixed support components 3 to move as well. As the sleeve 31 moves in the sliding groove 22 inside the clamp 21, one side of the distribution cabinet 4 will be in contact with one side of the wall 1. The entire back of the distribution cabinet 4 will be in uniform contact with the wall 1, providing support and friction. This ensures that the distribution cabinet 4 is not easily damaged during daily switching operations or when subjected to external forces. Shaking and vibration occur. When the distribution cabinet 4 moves closer to the wall 1, the elastic arc plate 5 fixed on the outside of the distribution cabinet 4 will also squeeze and push the moving block 27 that is in contact with it to move. When the moving block 27 moves, the compression spring 25 applies force to the clamping block 24, so that the side of the clamping block 24 with the arc shape is in close contact with the sleeve 31. At this time, the clamping block 24 cooperates with the clamping rod 21 to clamp the sleeve 31. Then, the nut 29 is screwed onto the screw 26, and one side of the nut 29 is in contact with one side of the moving block 27. When the distribution cabinet 4 is subjected to external force, the plug 32 will shake. Due to the arrangement of multiple connecting springs 33, the plug 32 is allowed to move to a certain extent within the sleeve 31. At the same time, the connecting springs 33 can absorb and buffer the impact and vibration of the components during operation, preventing the distribution cabinet 4 from deforming. When the connecting springs 33 deform, they will also exert a force on the sleeve 31. The force on the sleeve 31 is transmitted to the clamping block 24, causing the clamping block 24 to slide in the sliding groove 22. When the clamping block 24 pushes the moving block 27 through the compression spring 25, the moving block 27 will squeeze the elastic arc plate 5 that it is in contact with on one side, so that the elastic arc plate 5 moves closer to the distribution cabinet 4. The rubber strip 6 set on one side of the elastic arc plate 5 will clamp the distribution cabinet 4, improving the stability of the distribution cabinet 4. During this process, the distribution cabinet 4 is not attached to the wall 1, but is still restricted and fixed by the support component 3, and the movement of the support component 3 is buffered to avoid directly pulling the positioning component 2 and prevent the positioning component 2 from being pulled off the wall 1. When the distribution cabinet 4 is not subjected to external force, the elastic arc plate 5 restores its deformation and pushes the moving block 27 to move. Since the locking block 28 slides in the groove 23, the moving block 27 can be accurately reset. At the same time, the compression spring 25 restores its deformation, so that the relative position between the clamping block 24 and the moving block 27 is restored. The nut 29 screwed on the screw 26 re-fits with the moving block 27, and the clamping block 24 re-fits tightly with the sleeve 31, which, together with the locking rod 21, clamps the sleeve 31.
