Abstract
The invention relates to a locking device of a low-voltage switch cabinet. The locking device comprises a locking pin arranged on a low-voltage switch cabinet door and a closer arranged on a low-voltage switch cabinet body. The locking pin comprises a thin and long base body and a protruding head arranged at the end of the base body, the protruding head is wider than the base body, and a hollowed-out lock hole is formed in the middle of the front end of the protruding head. The closer comprises a locking pin inserting opening formed in a top plate of the cabinet body and a closer shell arranged on the rear portion of the locking pin inserting opening, and a first locking device body and a second locking device body are arranged in the closer shell. The first locking device body conducts locking in the mode that the protruding head is clamped through acute-angle protrusions on spring clip pieces, the second locking device body conducts locking in the mode that a bent hook on a locking bolt stretches into the lock hole in the protruding head. By means of the locking device, locking can be conducted on the low-voltage switch cabinet twice, safety locking of the low-voltage switch cabinet is kept during operation and temporary locking is conducted on the low-voltage switch cabinet during overhaul.

Summary of the invention
the object of this invention is to provide a kind of locking device of low-tension switch cabinet, this device can carry out secondary locking to low-tension switch cabinet, keeps the safety locking of low-tension switch cabinet in operation, in maintenance, low-tension switch cabinet is carried out to interim locking.
for solving the problems of the technologies described above, technical scheme of the present invention is as follows:
a locking device for low-tension switch cabinet, comprises the stop pin being arranged on low voltage switchgear door and is arranged on the closer composition on low voltage switchgear body, it is characterized in that,
described stop pin comprises elongated matrix and the outstanding head that is arranged on matrix end, and outstanding head has the width wider than matrix, and matrix and outstanding head are provided with arc corner in intersection, and the front center of giving prominence to head is provided with the lockhole of hollow out;
closer comprises the stop pin insert port being arranged on cabinet top board and is arranged on the closer shell at stop pin insert port rear portion, is provided with the first locking device and the second locking device in closer shell;
the first locking device comprises four steady pins of orthogonal arrangement, wherein between two steady pins of stop pin direction of insertion one side, be connected with the first spring clip, the two ends of the first spring clip are wrapped in respectively on two steady pins, the first spring clip is exceptionally also enclosed with and is wound around folder in the wound portion of steady pin, be wound around folder for further fixing the first spring clip, the middle part of the first spring clip has inside acute angle projection, between two steady pins of stop pin direction of insertion opposite side, be provided with the second spring clip with the first spring clip symmetry, the acute angle projection subtend setting of the acute angle projection of the first spring clip and the second spring clip, distance between two acute angle projections equals the width of stop pin matrix,
the second locking device comprises mechanical lock and the locking bolt with crotch, and mechanical lock is enough controlled locking bolt and rotated, and the crotch after pin insertion stop pin insert port to be locked on locking bolt inserts the lockhole on outstanding head, and stop pin is locked again.
the present invention has following technique effect:
1, can carry out secondary locking to low-tension switch cabinet, the locking of twice can be guaranteed being perfectly safe of locking device;
once 2 locking devices break down, owing to there being twice guarantee, can be because do not cause the actual effect of locking device for this reason;
3, in maintenance, can carry out interim locking to low-tension switch cabinet.
Brief description of the drawings
below with reference to accompanying drawing, specific embodiments of the invention are described in further detail, wherein:
fig. 1 is the low-tension switch cabinet schematic diagram of the embodiment of the present invention 1;
fig. 2 is the low-tension switch cabinet locking device of the embodiment of the present invention 1 schematic diagram under opening;
