Specific implementation mode
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model
Define.
Please refer to attached drawing 1-4, a kind of lock construction of ring main unit cabinet door of the utility model, the ring main unit include cabinet 1 and
Cabinet door 2 on 1 chamber of cabinet, the side plate being set on cabinet are set, and on the chamber top of the cabinet 1, setting one is lateral
Plate, transverse plate middle part are provided with key rotary switch 3, and the key rotary switch 3 is connected to by circuit to be arranged in the side
The electromagentic switching apparatus 4 of plate upper and lower part；
The electromagentic switching apparatus 4 includes cylindrical shell 41 and the electromagnetic wire for being set to 41 interlayer side wall of the cylindrical shell
Circle 42, the inner cavity of the shell 41 is provided with electromagnet 44, and end is provided with sealing plate thereafter, and spring 5 is provided on sealing plate, described
Spring 5 withstands on 44 rear end of electromagnet, and the electromagnet 44 is in convex, and nose is plug division；In no power, spring 5 can incite somebody to action
Electromagnet 44 keeps its front end small diameter cylindrical end exposed to sinciput；
2 medial surface edge upper part of the cabinet door and lower part are respectively arranged with the socket joint block 21 with arc bridge opening 23, the electricity
