Abstract

The invention discloses a rail transit platform screen door lock. The lock comprises a mounting base and a locking mechanism arranged on the mounting base. The locking mechanism comprises a lock disc arranged on the mounting base through a rotating shaft, a lock arm arranged on the mounting arm and a drive mechanism. A lock opening matched with a sliding door lock pin is arranged on the lock disc. The lock disc is provided with a lock-up position for limiting the sliding door lock pin in the lock opening and a releasing position for releasing the sliding door lock pin. The lock arm is provided with a first working position abutting against the lock disc to keep the lock disc in the lock-up position state or in the releasing position state and a second working position for releasing the lock disc. The drive mechanism is used for driving the lock arm to be switched between the first working position and the second working position. The invention further discloses a rail transit platform screen door. By means of the rail transit platform screen door lock and the rail transit platform screen door, the lock disc and the lock arm are controlled in a linkage mode, the drive mechanism is combined to drive the lock arm to move so as to achieve the function of closing or locking of the sliding door lock, the overall structure is simple, the processes of locking and unlocking are smooth, and accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of rail transit shield door design, and in particular relates to a rail transit shield door lock and a rail transit shield door. Background technique [0002] In the screen door industry, the sliding door is an important channel between the daily operating track and the platform, and it is also an important unit to ensure the safety of passengers. The door lock is an important mechanism in security. [0003] The design of the door lock must include two important functional contents: 1. When the sliding door is driven by the motor through the belt to the closed state, the lock pin of the sliding door activates the door lock to lock. , the sliding door cannot be opened by external force, thus playing a role of safety locking. And when the door lock receives the unlock signal, the electromagnet (electromagnetic push rod) in the door lock is energized and activated, and is unlocked through the connecting rod. ...
