Description

Technical Field

[0001] This utility model relates to the field of switch cabinet auxiliary equipment technology, specifically to a novel split rear sealing plate. Background Technology

[0002] As is well known, low-voltage switchgear assemblies are devices responsible for the control, protection, conversion, and distribution of electrical energy in low-voltage power supply systems. Because low-voltage switchgear assemblies can be found in industrial sites, public places, and residential buildings, it can be said that wherever electrical equipment is used, this type of product is necessary.

[0003] The rear cover plate is mainly installed behind the switchgear bracket to form the switchgear cabinet. Its installation method primarily involves drilling mounting holes in the switchgear bracket, then drilling corresponding mounting holes in the rear cover plate, and finally inserting fasteners through the rear cover plate. However, this structure has the following drawbacks:

[0004] 1. A rectangular three-dimensional frame needs to be prefabricated, namely the switch cabinet bracket. The rear cover plate of the transmission is integrated and cannot be disassembled according to the usage requirements.

[0005] 2. When installing the back panel, most back panels do not have folded edges, which results in insufficient rigidity. Furthermore, without folded edges, the panels cannot be spliced ​​smoothly during assembly. A new type of split back panel is needed to solve this problem. Utility Model Content

[0021] The utility model will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0022] Example 1

[0023] refer to Figures 1 to 3 Example 1 describes a first rear sealing plate 1, with a second rear sealing plate 2 on one side of the first rear sealing plate 1. A heat dissipation vent 9 is provided between the first rear sealing plate 1 and the second rear sealing plate 2. A dustproof pad 14 is installed on the back of the heat dissipation vent 9. A limiting groove 6 is provided on the opposite side of the first rear sealing plate 1 and the second rear sealing plate 2. A cold-rolled connecting steel plate 8 is installed between the limiting groove 6. The cold-rolled connecting steel plate 8 is tightly fitted to the limiting groove 6. A locking bolt 10 passes through the cold-rolled connecting steel plate 8 and the first rear sealing plate 1 and the second rear sealing plate 2. The other side of the locking bolt 10 is threadedly locked by a nut 11. A second opening 15 is provided on the dustproof pad 14. The hole at the arc groove 13 in the middle of the second rear sealing plate 2 fits with the second opening 15 of the dustproof pad 14 and is connected by a pin. The dustproof pad 14 is made of rubber and fits tightly with the arc groove 13 on the back of the heat dissipation vent 9.

[0024] In this embodiment, the cold-rolled connecting steel plate 8 and the first rear sealing plate 1 are locked together by nuts 11 to achieve the assembly of the first rear sealing plate 1 and the second rear sealing plate 2.

[0025] Example 2

[0026] refer to Figures 1 to 2 Example 2 is described below. This embodiment further describes Example 1. It includes side edge 3 on both sides of the first rear sealing plate 1 and the second rear sealing plate 2. Front and rear edge 4 are provided at the upper and lower ends of the first rear sealing plate 1 and the second rear sealing plate 2. The edge of the first rear sealing plate 1 and the second rear sealing plate 2 is "L" shaped. Limiting holes 7 and first openings 12 are opened at the corresponding positions of the limiting groove 6 and the cold-rolled connecting steel plate 8. The limiting holes 7 and the first openings 12 coincide.

[0027] In this embodiment, the first rear sealing plate 1 and the second rear sealing plate 2 are both equipped with folded edges on all four sides. The folding process significantly enhances the rigidity of the aluminum plate by forming an "L"-shaped stress structure.

[0028] In practical applications, the device features a split rear sealing plate. Limiting grooves 6 are provided at the side edges 3 of both the first rear sealing plate 1 and the second rear sealing plate 2. These grooves are joined together by cold-rolled connecting steel plates 8, and then secured by locking bolts 10 that pass through the second rear sealing plate 2, the cold-rolled connecting steel plates 8, and the first rear sealing plate 1. Nuts 11 are then used to lock the plates, achieving the assembly of the first rear sealing plate 1 and the second rear sealing plate 2. The entire assembly process is simple and convenient. Furthermore, a locking groove is provided between the first rear sealing plate 1 and the second rear sealing plate 2. There is a heat dissipation vent 9, on the back of which is attached to the arc-shaped groove 13 by a dustproof pad 14. During use, the dustproof pad 14 can be removed to achieve heat dissipation. When not in use, the attachment can prevent dust from entering. The first rear sealing plate 1 and the second rear sealing plate 2 are equipped with folded edges on all four sides. The folding process forms an "L"-shaped stress structure, which significantly enhances the rigidity of the aluminum plate. Moreover, for seam splicing and close splicing, the folding design can ensure the splicing is natural and flat, thereby improving the practicality of the device.
