[0029] It should be noted that by first removing the pin 111, the mounting bracket 120 can be pulled out from inside the cabinet 1 via the placement plate 12, providing operators with a wider field of vision and facilitating the maintenance of electrical components, effectively improving maintenance efficiency. When pulled out, the hollow tube 121 and the telescopic rod 122 move simultaneously. After being pulled out a certain distance, the hollow tube 121 and the telescopic rod 122 will fall due to gravity. The placement plate 12 is supported by the support plate at the bottom of the telescopic rod 122. By pressing the limit post 1222 and applying a certain force, the telescopic rod 122 can be extended to adapt to complex ground environments. It should be noted that a certain length of cable is reserved when wiring inside the distribution cabinet for rewiring in case of short circuits. Therefore, pulling out the mounting bracket 120 will not have much impact.

[0030] When it is raining, the maintenance personnel will pull out the pin 111, then selectively pull the side baffles 103 on both sides forward. After pulling a certain distance, the pin 111 will be inserted into the side baffles 103 for fixing and limiting. Then, the locking pin 130 will be pulled down to pull it out of the slot 1060. After that, the top plate 106 will be pulled out of the mounting groove 105. After pulling it out a certain distance, the locking pin 130 will limit the top plate 106. The side baffles 103 and the top plate 106 on one side will shield the top and one side of the mounting bracket 120, allowing for maintenance of the inside of the cabinet 1. This also reduces most of the rainwater entering the low-voltage distribution cabinet. In windy conditions, the cabinet door may be blown by the wind, affecting maintenance efficiency. In this case, the movable rod 140 can be pulled to align the limiting groove 1040 with the limiting block 141, and the limiting block 141 can be inserted into the inside to prevent the cabinet door from being blown by the wind.
