Description

Drawer locking device of drawer cabinet

Technical Field

The utility model relates to a locking device, in particular to a drawer locking device of drawer cabinet.

Background

The drawer cabinet is an electrical control cabinet and is the most important safety for the operator. The drawer locking device commonly used at present is mechanical operation, and the drawer of the drawer cabinet is opened due to the possibility of misoperation under the condition that the control cabinet is electrified, so that great potential safety hazards exist.

Disclosure of Invention

In view of the problems existing in the prior art, the utility model provides a locking device of drawer cabinet drawer.

The technical scheme includes that the drawer locking device of the drawer cabinet is characterized by comprising a drawer door plate, a door coupling part, a fastener, a door coupling cam, a door coupling supporting frame, a vertical plate, an L-type support, a drawer front plate, a drawer bottom plate, a cabinet body cross beam, a molded case circuit breaker and a power supply plate, wherein the door coupling part comprises a door coupling shifting block, a door coupling guide rod and a door coupling rotating operation mechanism, the vertical plate and a L-type support are fastened on the drawer front plate together through screws, the power supply plate is fixed on the drawer bottom plate through screws, then the molded case circuit breaker is screwed down through the screws and the power supply plate, the door coupling cam is placed on the door coupling supporting frame and then is inserted into a square hole of a L-type support together, the door coupling shifting block in the door coupling part is connected with the molded case circuit breaker, one end of the door coupling guide rod penetrates through the door coupling cam, the door coupling supporting frame and the vertical plate and is fixed through the fastener, the other end of the door coupling rotating operation mechanism is connected with the bolt and the drawer, the door coupling rotating operation part rotates the door coupling supporting frame to shift the door coupling cam to shift the door coupling supporting frame to shift out of the.

The utility model discloses produced beneficial effect is: according to the design, the door coupling support frame is shifted to move up and down by rotating the door coupling cam through the operating door coupling part, so that the door coupling support frame is inserted into and pulled out of a cabinet body cross beam; meanwhile, the door coupling shifting block shifts the molded case circuit breaker to be powered on and powered off, so that the functions of power-on locking and power-off opening are achieved, and the safety of an operator is guaranteed.
