Abstract

The invention relates to the field of elevators, in particular to an elevator door lock switch. The elevator door lock switch comprises a switch bottom box, a main contact device, a secondary contact device and a circuit system, wherein the secondary contact device is connected with the circuit system; one side of the switch bottom box is provided with a mounting hole, the surface of the switch bottom box is covered by a cover plate, and the switch bottom box is provided with a rotating rod connecting assembly; and the rotating rod connecting assembly comprises a bolt pin and a rotating shaft which are mutually rotationally connected, the bolt pin passes through the mounting hole, the rotating shaft is rotationally arranged on the switch bottom box, the rotating shaft is connected with a telescopic device for recovering the position of the rotating shaft, a metal contact sheet connected with the main contact device and a safety device for protecting the safety are arranged on the boltpin, and the rotating shaft passes through the cover plate and is connected with a rocker arm assembly. The elevator door lock switch has the advantages that: the switch can play a role of a switch of a safety door lock under the conditions of simultaneous mechanical and electric control and simultaneous action, and the switch is safer and more reliable.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator door lock switch. Background technique [0002] Elevators play an extremely important role in the work and life of modern society and bring great convenience to people. Therefore, the safe use of elevators is very important. The mechanical part of the traditional safety switch is separated from the electrical part. The traditional safety switch is mainly through the connection and disconnection of the contact switch on the lock hook of the elevator door lock and the silver contact plug of the door lock device of the pointed hall. Control the switch of the elevator safety door lock. The traditional mechanical control is prone to safety hazards, and there are more problems in the stability of the interaction with the electrical part. Contents of the invention [0003] In order to solve the above-mentioned technical problem that the mechanical part and the electrical part of...
