Anti-theft electromagnetic lock device for rail transit platform door

Abstract

The invention discloses an anti-theft electromagnetic lock device for a rail transit platform door, and relates to the technical field of electromagnetic locks. The anti-theft electromagnetic lock device for the rail transit platform door comprises an anti-theft lock body, wherein an electromagnetic controller is fixedly installed in the anti-theft lock body; and the right side of the electromagnetic controller is fixedly connected with a first magnet. According to the anti-theft electromagnetic lock device for the rail transit platform door provided by the invention, a control button is pressed down, the electromagnetic controller is started and drives a fixed column to move through the first magnet, a second magnet, a spring and a fixed strip (the fixed column is moved out of a lock groove), then the electromagnetic controller is disconnected, and the fixed column is reset through the spring and the second magnet (the fixed column is moved into a sliding groove), so that the anti-theft electromagnetic lock is conveniently opened and closed; an opening and closing mechanism is stable in operation, simple in structure and convenient to use; and when temporary power failure occurs,the opening and closing work of the anti-theft electromagnetic lock can be achieved through a standby power source set, so that a high practical performance is achieved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic locks, in particular to an anti-theft electromagnetic lock device for rail transit platform doors. Background technique [0002] With the development of science and technology and the progress of the times, the transportation is more and more developed, and the subway is becoming more and more popular in many cities. All new urban rail transit projects in the country are designed and installed with anti-theft electromagnetic lock devices. The design of electromagnetic locks and electromagnets Similarly, it uses the principle of electromagnetism. When the current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction force to tightly absorb the adsorption iron plate to achieve the effect of locking the door. [0003] Existing anti-theft electromagnetic locks, when encountering a temporary power failure, the anti-theft electromagnetic locks cannot ope...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the existing anti-theft electromagnetic locks. When encountering a temporary power failure, the anti-theft electromagnetic locks cannot operate normally, which reduces the practical performance of the equipment, and most of the existing anti-theft electromagnetic locks do not have The emergency start device prevents passengers from leaving, which increases the rate of accidents, and proposes a rail transit platform door anti-theft electromagnetic lock device
