Abstract

The invention provides a locking and unlocking device for a shield door of a track traffic platform. The locking and unlocking device comprises a lock bracket, and a locking mechanism, an electromagnetic unlocking mechanism, a manual unlocking mechanism and a signal generating mechanism which are arranged on the lock bracket, wherein the locking mechanism is arranged on the front side face of thelock bracket, and comprises left and right locking pieces and left and right bolts which are arranged symmetrically; the left and right locking pieces and the left and right bolts are rotationally arranged on the lock bracket respectively; a locking piece return spring is connected between the left and right locking pieces; a bolt return spring is connected between the left and right bolts; a locking and unlocking relation is formed between the left locking piece and the left bolt; and a locking and unlocking relation is formed between the right locking piece and the right bolt. In the invention, locking and unlocking of a movable door are realized by limiting a movable door limiting pin connected with the movable door through the left and right locking pieces, so that high integration level is realized, and simultaneous locking and unlocking of left and right doors can be realized; and the signal generating mechanism is integrated in the device, so that the size is reduced, and the installation application range is expanded.

Description

technical field [0001] The invention relates to a door lock, in particular to a locking and unlocking device for a screen door of a rail transit platform. Background technique [0002] Special safety requirements for the subway environment. After the movable door is closed, the locking mechanism can prevent the door from being opened by external force; when the movable door is opened and in the normal operation mode, the door lock of the movable door can be automatically unlocked; in the emergency operation mode, the platform staff Or passengers can manually open the movable door to realize unlocking. [0003] The existing double-closed screen door consisting of left and right door panels is usually locked and unlocked through a locking mechanism designed separately for each door, and the locking and unlocking signal and manual unlocking signal are set separately from the locking mechanism, which seems very scattered. , and increased maintenance workload.
