Description

Technical Field

[0001] The utility model relates to the field of low - voltage cabinet brackets, and particularly to a low - voltage cabinet tray bracket. Background Technique

[0002] In the field of power equipment installation, as an important power distribution equipment, the stability and safety of low - voltage cabinets are crucial for the operation of the entire power system. However, there are often some problems with traditional low - voltage cabinet installation methods. For example, when the low - voltage cabinet is directly placed on the ground, it is easy to get damp, which affects the service life of the equipment. At the same time, during transportation or use of the low - voltage cabinet, due to vibration or jolting, the internal components of the equipment may loosen or be damaged.

[0003] To solve these problems, some low - voltage cabinet tray bracket products have emerged in the market. However, most of these products are simply designed and can only provide basic supporting functions, unable to meet the comprehensive requirements of low - voltage cabinets in terms of moisture - proof, heat dissipation, and shock absorption. In addition, when fixing low - voltage cabinets with traditional tray brackets, connection methods such as bolts or buckles are usually used, which are cumbersome to operate and easily damage the low - voltage cabinets.

[0004] Therefore, the market urgently needs a new type of low - voltage cabinet tray bracket that can not only support the low - voltage cabinet but also provide functions such as moisture - proof, heat dissipation, and shock absorption, and at the same time, it also needs to have the characteristics of simple installation and convenient operation. Content of the Utility Model

[0005] The purpose of the utility model is to provide a low - voltage cabinet tray bracket to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A low - voltage cabinet tray bracket includes a tray for supporting the low - voltage cabinet. Legs are fixed to the bottom surface of the tray. Assembly grooves are opened on the top surface of the tray. Clamping blocks are inserted on both sides of the assembly grooves. A limiting sleeve is sleeved inside the assembly grooves, and the limiting sleeve pushes the clamping blocks to move towards the inside of the groove of the tray. A reserved opening is opened on the bottom surface of the tray, and a rubber cushion plate is fixed to the top surface of the bottom plate of the tray.

[0007] Preferably, the tray is in a square frame structure. Legs are fixed at the four corners of the bottom surface of the tray. A cushion plate is fixed under every two legs, and a rubber gasket is fixed to the bottom surface of the cushion plate.

[0008] Preferably, the rubber cushion plate is in a "day" - shaped plate structure, the reserved opening is an oblong opening, and there are multiple reserved openings.

[0009] Preferably, the assembly groove is an annular groove, the inner annular surface of the pallet has an installation groove, the surface of the installation groove has a through opening, there are two installation grooves, the two installation grooves are symmetrically distributed about the groove opening of the pallet, the clamping block and the through opening correspond one-to-one, the clamping block is inserted into the through opening, and one end of the clamping block has a bevel on the top surface.

[0010] Preferably, a rubber band is fixed between the top surface and the bottom surface of the mounting groove. When the limiting sleeve pushes the clamping block, the clamping block stretches the rubber band to produce elastic deformation.

[0011] Preferably, the top surface of the limiting sleeve has through holes at all four corners, and a screw is inserted into the through hole. The bottom end of the screw is fixed to the bottom surface of the assembly groove. The height of the screw is greater than the height of the limiting sleeve, and a nut is screwed onto the top end of the screw.

[0022] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the attached drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, and are not used to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1-7 , the present utility model provides a technical solution: a low-voltage cabinet pallet support, including a pallet 1 for supporting the low-voltage cabinet. The bottom surface of the pallet 1 is fixed with support legs 2. The pallet 1 is in a square frame structure, and support legs 2 are fixed at the four corners of the bottom surface of the pallet 1. A backing plate 3 is fixed below every two support legs 2. A rubber gasket 4 is fixed to the bottom surface of the backing plate 3. A reserved opening 6 is provided on the bottom surface of the pallet 1, and a rubber backing plate 5 is fixed to the top surface of the bottom plate of the pallet 1. The rubber backing plate 5 is in a "day" - shaped plate structure. The reserved opening 6 is an oblong opening, and there are multiple reserved openings 6. Place the pallet 1 on a flat ground. At this time, the backing plate 3 cooperates with the support legs 2 to support the pallet 1, and the rubber gasket 4 is between the ground and the backing plate 3, increasing the friction between the backing plate 3 and the ground. Then place the low-voltage cabinet in the groove of the pallet 1. At this time, the pallet 1 cooperates with the support legs 2 and the backing plate 3 to support the pallet 1, thereby achieving moisture-proofing at the bottom of the pallet 1. Moreover, the reserved openings 6 provided on the bottom surface of the pallet 1 meet the heat dissipation requirements of the bottom plate of the low-voltage cabinet, and the rubber backing plate 5 is clamped between the pallet 1 and the low-voltage cabinet, increasing the shock absorption effect on the bottom of the low-voltage cabinet.

[0024] The top surface of the pallet 1 has an assembly groove 7. Clamping blocks 11 are inserted into both sides of the assembly groove 7. A limiting sleeve 12 is fitted inside the assembly groove 7. The limiting sleeve 12 pushes the clamping blocks 11 into the groove of the pallet 1. The assembly groove 7 is an annular groove. The inner annular surface of the pallet 1 has an installation groove 9. The surface of the installation groove 9 has a through-hole 8. There are two installation grooves 9, symmetrically distributed about the opening of the pallet 1. The clamping blocks 11 correspond one-to-one with the through-holes 8. The clamping blocks 11 are inserted into the through-holes 8. One end of the clamping block 11 has an inclined surface on its top surface. A rubber band 10 is fixed between the top surface of the mounting groove 9 and the bottom surface of the mounting groove 9. When the limiting sleeve 12 pushes the clamping block 11, the clamping block 11 stretches the rubber band 10 to produce elastic deformation. The top surface of the limiting sleeve 12 has through holes 13 at the four corners. A screw 14 is inserted into the through hole 13. The bottom end of the screw 14 is fixed to the bottom surface of the assembly groove 7. The height of the screw 14 is greater than the height of the limiting sleeve 12. A nut 15 is screwed onto the top end of the screw 14. After the pallet 1 is placed inside the groove of the pallet 1, the limiting sleeve 12 is fitted into the assembly groove 7. When the limiting sleeve 12 is pushed down, the through hole 13 is fitted onto the screw 14. As the limiting sleeve 12 falls, the limiting sleeve 12 pushes the clamping block 11 along the inclined surface. The clamping block 11 retracts into the through hole 8, and the clamping block 11 stretches the rubber band 10 to deform. The rubber band 10 is clamped between the low-voltage cabinet and the clamping block 11, increasing the friction between the clamping block 11 and the low-voltage cabinet. The clamping block 11 clamps the bottom of the low-voltage cabinet to prevent the low-voltage cabinet from shaking in the pallet 1.

[0025] The usage procedure for this low-voltage switchgear tray support is as follows: Place the assembled tray 1 on a selected flat surface, ensuring that the pad 3 and rubber pad 4 are in close contact with the ground to increase friction and moisture resistance. Confirm that the reserved opening 6 on the bottom of the tray 1 meets the heat dissipation requirements of the low-voltage switchgear bottom plate. Carefully place the low-voltage switchgear into the groove of the tray 1, ensuring that the bottom of the low-voltage switchgear is in close contact with the rubber pad 5 to increase shock absorption. Fit the limiting sleeve 12 into the assembly groove 7, ensuring that the through hole 13 is aligned with the screw 14. Push the limiting sleeve 12 down along the screw 14, causing it to push the clamping block 11 along the inclined surface of the clamping block 11 into the through hole 8. During the retraction process, the clamping block 11 will stretch the rubber band 10, causing it to undergo elastic deformation. The rubber band 10 clamps between the low-voltage switchgear and the clamping block 11, increasing friction. When the limiting sleeve 12 is pushed down to the appropriate position, the nut 15 is screwed onto the top of the screw rod 14 to fix the position of the limiting sleeve 12.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
