At the same time, the functional module on the bracket and the control module on the cabinet door can be connected by setting a connector, thereby ensuring the reliable use of the power cabinet function. Secondly, the locking component is located on the outer periphery of the inner side of the connection between the bracket and the cabinet frame, with high space utilization, and has the advantages of ease of use and high reliability.

[0038] A specific application of this embodiment is: Figure 1-3 In the normal use state of the power cabinet, various functional modules are installed on the bracket 1, and the control module and display module are installed on the cabinet door 3. The modules between the two are interconnected through the connector 5;

[0039] When it is necessary to remove the cabinet frame 2 and the cabinet door 3 from the hanging seat 1: open the cabinet door 3 and disengage the connector 5. At this time, the modules on the hanging seat 1 and the cabinet door 3 are disconnected. Both hands pass through the handle 21 and hold it. At the same time, the cross bar 66 is pushed inward. At this time, the cross bar 66 drives the gear seat 65 to slide in the guide sleeve 64. At this time, the gear seat 65 is meshed with the gear 63 and drives the cam 62 to rotate in the hanging seat 1. After the cam 62 rotates, it disengages from the locking groove 61. At this time, the hanging seat 1 and the cabinet frame 2 are disengaged from the lock. The cabinet frame 2 and the cabinet door 3 are removed from the hanging seat 1 by holding the handle 21. The cabinet frame 2 is taken out while releasing the cross bar 66.

[0040] Installation of the cabinet frame 2 and cabinet door 3: Pass the handle 21 and hold it, dock the cabinet frame 2 with the bracket 1, then move the cross bar 66 and rotate the cam 62 to the inside of the bracket 1. After the cabinet frame 2 and the bracket 1 are fully docked, release the cross bar 66, and under the action of the locking spring 67, drive the gear seat 65 and the cross bar 66 to reset. At this time, the cam 62 is driven into the locking groove 61 through the engagement of the gear seat 65 and the gear 63, and the locking after docking is completed. Finally, the connector 5 is plugged in, and the entire power cabinet operates normally.
