Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet door anti-bending technology, and in particular to a distribution cabinet door with an anti-bending structure. Background Technology

[0002] Distribution cabinets, also known as switch cabinets or distribution boxes, are indispensable equipment in power systems, used for centralized distribution and control of electrical energy. They play a core role in electrical engineering, ensuring the safe and efficient delivery of electrical energy to various power consumption points. Currently, there are many types of AC low-voltage distribution cabinets, such as GGD, GCS, MNS, and GCK. The rear door of this distribution cabinet is made of 1786×386mm cold-rolled steel plate. During the production of the rear door, the operator needs to bend the outer wall of the cold-rolled steel plate using a bending die to create creases. Then, the operator folds the plate along these creases. During the folding process, the cold-rolled steel plate may bend and deform due to uneven force applied by the operator. At the same time, the interior of the formed cabinet door will have empty grooves that cannot support the folding structure on both sides of the door. This makes the produced cabinet door easily deformed when subjected to impact. Therefore, a distribution cabinet door with a bending-resistant structure has been designed. Utility Model Content

[0036] It should be noted that the cabinet door body 1 is made of 1.5 cold-rolled steel plate. The upper and lower extension plates 201 are multiple cold-rolled steel plates extending from the four sides of the cabinet door body 1. The multiple upper and lower back plates 301 are formed by bending the multiple upper and lower extension plates 201 with a bending tool. The upper and lower extension plates 201 form a closed loop after multiple bends. The closed loop upper and lower back plates 301 are then fixed to the inner wall of the cabinet door body 1 by welding. Similarly, the left and right back plates 302 are formed by bending the multiple left and right extension plates 202 with a bending tool. The left and right extension plates 202 form a closed loop by bending and are then fixed to the inner wall of the cabinet door body 1 by welding.

[0037] Specifically, the outer walls of the multiple left and right backrest plates 302 are provided with multiple process holes 401, and the outer wall of the cabinet door body 1, located at the end away from the process holes 401, is provided with multiple bent end faces 4.

[0038] It should be noted that the process hole 401 is used for welding the lock rod guide screw and installing the door hinge.

Through the connection of multiple protective corners 501, the connection between multiple upper and lower retaining plates 301 and the left and right retaining plates 302 can be strengthened.

[0043] Working principle of this utility model:

[0044] It should be noted that the specific operation is as follows: multiple upper and lower retaining plates 301 are formed by folding the ends of multiple upper and lower extension plates 201 in multiple sections. Similarly, left and right retaining plates 302 are formed by folding the ends of multiple left and right extension plates 202 in multiple sections. The upper and lower retaining plates 301 and left and right retaining plates 302 can increase the strength of the cabinet door body 1. The operator can install them at the front end of the distribution cabinet through the process hole 401. The bent end face 4 is set at the front end of the cabinet door body 1, which can increase the strength of the cabinet door body 1. Multiple protective corners 501 are fitted at the corner connection of multiple upper and lower retaining plates 301 and left and right retaining plates 302. Multiple protective corners 501 can strengthen the corner connection strength of upper and lower retaining plates 301 and left and right retaining plates 302.
