[0014] This utility model provides an assembled power distribution cabinet that is easy to maintain. Compared with the prior art, it has the following advantages:

[0015] 1. This modular power distribution cabinet, which is easy to maintain, uses a motor to drive a worm gear, which in turn drives a worm wheel, which in turn drives a rotating shaft, which in turn drives a rotating rod. The rotating rod, through a linkage column, causes the rotating sleeve to roll inside the linkage groove rod, and through the linkage groove rod, it drives the fixed plate to move forward. During the movement of the fixed plate, the rollers roll inside the track plate, thereby realizing the forward movement of the power components. By moving forward, all the front of the components are directly exposed, eliminating blind spots and providing unobstructed operating space.

[0016] 2. This modular power distribution cabinet, designed for easy maintenance, features a limit switch assembly. By rotating a handwheel, a lead screw rotates, causing a slider to move. The slider then moves a fixed column synchronously, adjusting the distance between the fixed column and the center point of rotation of the limit rod. A shorter distance results in a smaller rotation angle of the limit rod and a shorter forward movement of the moving unit; a longer distance results in a larger rotation angle of the limit rod and a greater forward movement of the moving unit. This allows for adjustment of the forward movement distance of the power components, ensuring a compliant and safe distance between live parts and the maintenance area. Attached Figure Description

[0027] The drive unit 22 is located below the cabinet 1 and is used to drive the moving unit 21.

[0028] In this embodiment, the mobile unit 21 further includes a base 216 fixedly installed on the top of the fixed plate 213, and an installation plate 217 is fixedly installed inside the base 216. An installation bracket 218 is fixedly installed on the front side of the installation plate 217, and several power components are fixedly installed through the installation bracket 218.

[0029] During the movement of the fixed plate 213, the roller 215 rolls inside the track plate 212, thereby enabling the electrical components to move forward. By moving forward, the front of all components is directly exposed, eliminating blind spots and providing unobstructed operating space.

[0030] In this embodiment, the drive unit 22 includes a linkage groove rod 221 fixedly installed at the bottom of the fixed plate 213, and a rotating shaft 222 is rotatably installed inside the bottom plate 211. A rotating rod 223 is fixedly installed at the top of the rotating shaft 222, and a linkage column 224 is fixedly installed at the upper end of the rotating rod 223. A rotating sleeve 225 is rotatably installed on the surface of the linkage column 224, and the rotating sleeve 225 rolls inside the linkage groove rod 221. A worm gear 226 is fixedly installed on the surface of the rotating shaft 222, and a bearing seat 227 and a motor 228 are fixedly installed at the bottom of the cabinet 1.
