The power distribution cabinet includes a cabinet body, a front door is arranged on the cabinet body, and the front door is hinged on the cabinet body. There are several horizontal partitions in the cabinet body for fixing the switch accessories. The power distribution cabinet usually produces spare parts first, and then uniformly assembles them in the workshop;

[0003] Among them, the existing patent CN201820955565.9 is an adjustable distribution cabinet support frame, which sets the support beam of the distribution cabinet support frame to two states, one dynamic and one static. Through the adjustable movable support beam, the distance between the two support beams can be controlled, and the position of the movable support beam can be appropriately adjusted according to the width of the distribution cabinet, so that the distribution cabinet can be firmly placed on the support frame, which is convenient for assembling the distribution cabinet. The movable support beam is arranged into multiple separate short beams, and the adjustment of each short beam does not interfere with each other. Multiple models of distribution cabinets can be placed on one support frame, which makes the support frame more applicable and improves the utilization rate of the placement space on the support frame.

[0004] However, most of the existing distribution cabinet support frames are fixed structures inside the distribution cabinet and cannot be extended outward. If the staff needs to inspect the inside of the distribution cabinet, there is a lack of light inside the distribution cabinet, and the staff needs to put their heads into the interior of the distribution cabinet during inspection, which is troublesome and dangerous. Therefore, it does not meet the existing needs. We have proposed an internal support frame for the distribution cabinet. Utility Model Content
