Lock of anti-explosion elevator floor door

Abstract

Disclosed is a lock of an anti-explosion elevator floor door. An armature and an electromagnetic coil are disposed in an anti-explosion shell, one end of the armature extends out from one end of the anti-explosion shell and is connected with one end of a connecting rod via a hinge pin, the connecting rod is connected with a mounting shell via a shaft, a sliding pair is disposed between the armature and the anti-explosion shell, a spring is sleeved on the armature and located between the inner side of the anti-explosion shell and the electromagnetic coil, a stuffing box is hermetically arranged at the other end of the anti-explosion shell via bolts, a lead is connected with the electromagnetic coil via the stuffing box, an opening is arranged at the front end of an opening hook, the rear end of the opening hook is disposed in the mounting shell via a hinge pin, a lock hinge pin is disposed in the opening of the front end of the opening hook, the middle of a lock hook is disposed in the mounting shell via a lock shaft, a hook is disposed at the left end of the lock hook, an outward turning combination portion is arranged on the left side of the opening hook and matches with the hook at the left end of the lock hook, and the right end of the lock hook is connected with the other end of the connecting rod via a hinge pin. The lock of the anti-explosion elevator floor door can meet the anti-explosion requirement, and safety of the lock of the elevator floor door is improved.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to elevators, in particular to an explosion-proof elevator landing door lock. Background technique: [0002] The use environment of the elevator is complex, and usually used for a long time. Due to the heat generated by the motion friction, the temperature of the elevator accessories is high; in addition, the elevator is used in a place with a large flow of people, so the safety requirements for the elevator accessories are high, especially It is the explosion-proof requirement for live accessories. The landing door lock of the elevator needs to be installed on each floor, and it is used to reliably lock the elevator door of a certain floor. The existing elevator landing door locks only realize the locking of the landing doors, without considering the explosion-proof requirements of the elevator, resulting in low safety. Invention content: [0003] The object of the present invention i...
