Description

A kind of cabinet door lock of switchboard

Technical field

The utility model relates to the cabinet door lock of a kind of door lock, particularly a kind of switchboard.

Background technology

Switchboard can supply industrial and mining enterprises, power plant and transformer station are as the control and the protection of electric utility, and be used for the place of frequent operation, the cabinet door lock of existing a kind of switchboard comprises lock tube, lock core and split washer, wherein, described split washer is positioned at lock tube, and described split washer axially blocks a plain cushion, the inner peripheral surface matched in clearance of the outer peripheral face of plain cushion and described lock tube; Described lock core passes split washer and plain cushion is positioned at lock tube, split washer and lock core shaft are to clamping, the switch cabinet door lock of this structure, because split washer is fixed on the lock core, in a single day be fixed up its position, just can't adjust again, and often in the switchboard transportation, switchboard has distortion to a certain degree, therefore when switchboard is out of shape, will cause the distortion of opening ring washer to come off, lose thereby cause door lock to come off, and owing to be to carry out spacingly with fixing split washer, the scope that cooperates of link is restricted on lock core and the cabinet, the gap of lock core and cabinet link is bigger, thereby causes the location of lock core and cabinet inaccurate.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of can not coming off because switchboard distortion and the cabinet door lock of the switchboard of accurate positioning.

In order to solve the problems of the technologies described above, the cabinet door lock of a kind of switchboard of the present utility model, comprise the lock tube that is fixed on the cabinet door, lock core and lock core back-up ring, wherein, the middle part of described lock tube inner peripheral surface is provided with a step, and described lock core back-up ring is positioned at lock tube and is positioned at the below of described step, the inner peripheral surface matched in clearance of the outer peripheral face of lock core back-up ring and lock tube; Described lock core is positioned at lock tube, and described lock core back-up ring is connected the lower end of described lock core, described lock core and described lock core back-up ring be connected to flexible connection.

The cabinet door lock of above-mentioned a kind of switchboard, wherein, above-mentioned flexible connection is for being threaded.

Adopt the switch cabinet door lock of said structure, because lock core and lock core back-up ring are for flexibly connecting, the lock core back-up ring just can be adjusted its position according to actual needs on lock core, then in the transportation of switchboard, lose with regard to not causing coming off of door lock because of the distortion of switchboard, and lock core also can be regulated as required with the scope that cooperates of cabinet link, thereby reduces the gap between lock core and the cabinet link, improves the accuracy of its location.
