[0013] The utility model will be further explained in detail below in combination with the drawings and specific implementation.

[0014] A switch cabinet grounding locking device, including switch cabinet body 1, linkage cabinet door 2, grounding locking structure 3, the linkage cabinet door 2 is connected in the front side of switch cabinet body 1 by door shaft 4, the grounding locking structure 3 is set up on the inner side wall of switch cabinet body 1, and the grounding locking structure 3 is in contact with the bottom end of door shaft 4.

[0015] The bottom end of door shaft 4 is provided with contact rod 5 and embedded boss 6, contact rod 5 is set up at the bottom end of door shaft 4, and contact rod 5 is vertically arranged with linkage cabinet door 2, contact rod 5 and linkage cabinet door 2 can rotate with door shaft 4 as the pivot, embedded boss 6 is set up at the outer side end of contact rod 5, and contact rod 5 and embedded boss 6 can be in contact with grounding locking structure 3.

[0016] The grounding locking structure 3 is composed of switch structure 7, grounding wire 8, manual handle 9 and linkage contact handle 10, the grounding wire 8 is connected on the upper and lower sides of switch structure 7, the manual handle 9 and linkage contact handle 10 are coaxially arranged, and the manual handle 9 is arranged at the outer side of linkage contact handle 10, the manual handle 9 and linkage contact handle 10 are connected on the front side of switch structure 7, the bottom end of linkage contact handle 10 is provided with handle embedded groove 11, the embedded boss 6 can be embedded in handle embedded groove 11, and switch structure 7, grounding wire 8 and manual handle 9 are all embedded and hidden in switch cabinet body 1.

[0017] The working principle of the structure is simple, and mainly includes two aspects of cabinet door opening and cabinet door closing.

[0018] When the linkage cabinet door 2 is closed, the contact rod 5 arranged perpendicularly to the linkage cabinet door 2 is in contact with the linkage contact handle 10 in the grounding locking structure 3, and the embedded block 6 is embedded in the handle embedded groove 11, so that the grounding state cannot be achieved when the grounding locking structure 3 is switched under the influence of the closed cabinet door.

[0019] When the linkage cabinet door 2 is opened, the contact rod 5 arranged perpendicularly to the linkage cabinet door 2 is changed in angle along with the rotation of the door shaft 4, so that the embedded block 6 is separated from the handle embedded groove 11, and the internal grounding locking structure 3 can be switched, and the operator can also rotate the switch structure 7 through the manual handle 9 to change the switch state of the grounding locking structure 3.

[0020] The above is the preferred embodiment of the present application, and for those skilled in the art, according to the teaching of the present application, the changes, modifications, replacements and variations of the embodiments without departing from the principles and spirits of the present application still fall within the protection scope of the present application.
