At this time, the connecting spring is reset, pushing the locking ring rod to rotate, and the locking rod is moved out of the positioning groove. Workers can easily and quickly remove the corresponding faulty cabinet for repair or replacement, and then move the new cabinet along the track to one side of the bridge, and at the same time extend the extension rod and the locking rod into the installation groove, and then move the main cabinet, insert the abutment rod into the notch, rotate the locking ring rod in the ring tube, squeeze the connecting spring, and insert the locking rod into the positioning groove, so that the cabinet can be locked quickly and conveniently; it can also reduce the possibility of the cabinet or the main cabinet being stolen.

[0015] Furthermore, one end of the locking ring rod extending out of the ring tube is provided with a guiding inclined surface for the resisting rod to be squeezed.

[0016] By adopting the above technical solution and utilizing the guiding inclined surface, it is convenient for the resistance rod to push the locking ring rod to rotate.

[0017] The locket is a hinged door that is fixed on the top of the cabinet body and the hinged door frame, and the hinged door frame is hinged on the top of the cabinet body, and the hinged door frame is hinged on the hinged door frame.

[0018] By adopting the above technical solution, the arc-shaped side panels are used to increase the internal installation space of the cabinet and the main cabinet, and increase the utilization rate of the annular installation space; the sealing door is in contact with the arc-shaped side panels, so that the gaps between adjacent cabinets and between the main cabinet and the adjacent cabinets can be closed, so that the distribution cabinet can form a complete ring, which can reduce the accumulation of garbage between adjacent cabinets or between the cabinet and the main cabinet, and can also increase the aesthetic performance of the distribution cabinet; when the cabinet or the main cabinet needs to be repaired, the electromagnet block is energized to absorb the gear lever, and the baffle is used to close the gaps between adjacent cabinets and the main cabinet. The pressing spring is pressed, and the lever is disengaged from the positioning notch, and then rolls on the arc-shaped slide rail through the pulley, so that the sealed door can be rotated, and the cabinet or the main cabinet can be moved out from between the vertical rods; when the maintenance is completed, the cabinet or the main cabinet is slid into the limiting groove along the track, and the sealed door is rotated to make the sealed door contact with the arc-shaped side panel, and then the electromagnet block loses power, the pressing spring is reset, and the baffle is pushed outward, thereby pushing the lever out, and the lever is inserted into the positioning notch, so that the cabinet or the main cabinet can limit the sealed door, so that the sealed door can be fixed conveniently and quickly.

[0019] Furthermore, a maintenance opening is provided on the side wall of one of the sealed doors, and a first switch for controlling the power on and off of the electromagnet plate and a second switch for controlling the power on and off of the electromagnet block are provided on the side of the sealed door close to the bridge frame. A maintenance door is hinged on the side wall of the maintenance opening, a locking groove is provided on the side wall of the maintenance opening, and a lock body inserted into the locking groove is provided on the side wall of the maintenance door.
