Abstract

The invention discloses a locking device for a screen door in rail transit, which comprises a lock bracket, a locking mechanism arranged on the lock bracket, an electromagnetic release mechanism, a manual release mechanism and a signal generating mechanism. The locking mechanism is arranged on the front side surface of the lock bracket and comprises symmetrically arranged left and right locking blocks and symmetrically arranged left and right bolts, wherein the left and right locking blocks and left and right bolts are rotationally arranged on the lock bracket, respectively; a return spring ofthe locking block is connected between the left and right locking blocks; a bolt return spring is connected between the left and right bolts; and locking-releasing relation is separately formed between the left locking block and left bolt and between the right locking block and right bolt. In the invention, a sliding door is locked and released by limiting a sliding door stop pin connected with the sliding door by the left and right locking blocks, the integration level is high, the left and right doors can be locked synchronously through a simple adjustment, and the signal generating mechanism is integrated in the device so that the volume of the device is reduced and the range of installation and application thereof is expanded.

Description

technical field [0001] The invention relates to a door lock, in particular to a locking device for a rail transit screen door. Background technique [0002] 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. 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. Contents of the invention [0003] The object of the...
