[0002] Electrical cabinets are a general term for motor control centers. Electrical cabinets are used in situations where the load is relatively dispersed and there are fewer circuits. Motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] Electrical cabinets are mainly composed of a basic frame, partitions, sealing panels, left and right side panels, bottom panel, top panel, and door panels. The basic frame, partitions, sealing panels, left and right side panels, bottom panel, and top panel are generally connected by bolts to form the cabinet body. The door panel and the cabinet body are generally connected by hinges. When the door panel is open, due to its large size and heavy weight, it is not possible to fix the door panel by hinges alone. Over time, the door panel is prone to sagging to one side, causing the door lock and key hole to misalign, making it inconvenient to lock the door panel and affecting its use. Utility Model Content
