Problems solved by technology

At present, the explosion-proof method and measure adopted on the switch cabinet door is to use multiple bolt-type door locks on the door, so that the bolts on the cabinet door are screwed into the nuts on the cabinet body, and the cabinet door and the cabinet body are fastened. When opening the door, it is necessary to use a special key to unscrew the bolts one by one to open the cabinet door, which is cumbersome to operate and very inconvenient to use

Abstract

The invention relates to an anti-explosion door catch mechanism and a switch cabinet. The anti-explosion door catch mechanism comprises a set of cabinet body assembly mounted on cabinet body of the switch cabinet and a set of cabinet door assembly mounted on a cabinet door. The cabinet body assembly and the cabinet door assembly cooperate to lock or open the cabinet door of the switch cabinet. Thecabinet door assembly comprises a lock pin lock block and a latch lock block, and the lock pin lock block and the latch lock block are fixedly mounted on the cabinet body. The cabinet door assembly comprises latches, lock pins, fixed pin lock blocks, a conversion structure, transverse push rods, door catch fixing plates, door catches, sliding rod guide plates provided with guide holes, door catchlock blocks and sliding rods penetrating through the guide holes. A door handle is rotated, spring bolts of the latches move up and down in the vertical direction, the lock pins and the conversion structure are pushed, finally the door catches are pushed to become into horizontal motion, the door catches are horizontally inserted into door catch holes formed by the door catch lock blocks and thelatch lock block, the cabinet door of the switch cabinet is also locked in the horizontal direction, and the switch cabinet door is locked. The door lock handle rotates flexibly, mechanism operation force is small, operation is simple, use is convenient, and the anti-explosion performance is reliable.

Description

technical field [0001] The invention relates to the explosion-proof technical field when an arc fault occurs in a switchgear, in particular to an explosion-proof latch mechanism and a switchgear. Background technique [0002] Usually, when an arc short-circuit fault occurs in the switchgear, the strong arc current will instantly generate high temperature and high heat, heating the objects around the fault point, melting the metal objects around the fault point, burning combustible objects, and rapidly expanding air when heated, forming an explosion. If there are no explosion-proof measures for the switch cabinet door, when a fault occurs, the switch cabinet door will be blasted open instantly, which will seriously threaten and injure the safety of the operators and patrol personnel in front of the switch cabinet door. In order to ensure the safety of operators and inspectors, the switch cabinet door is required to have an explosion-proof function, and the surroundings of the...
