Door lock and rail transit platform door system

Abstract

The invention discloses a door lock and a rail transit platform door system. The slider assembly of the door lock is configured to be able to move between an unlocked position and a locked position, wherein the unlocked position allows the first The movement of a deadbolt assembly and the second deadbolt assembly, the locking position restricts the movement of the first deadbolt assembly and the second deadbolt assembly; the slider assembly is configured To be constrained in the unlocked position when the first deadbolt assembly is in the first released state and / or when the second deadbolt assembly is in the second released state, and only when the When the first lock tongue assembly is in the first stop state and the second lock tongue assembly is in the second stop state, it can move to the locking position. The door lock of the present invention can be locked only when the platform doors on both sides are fully closed, thereby completely avoiding the phenomenon that only one platform door is fully closed while the other platform door is not closed, thereby improving safety.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a door lock and a rail transit platform door system. Background technique [0002] At present, most rail transit platform doors (such as subway platform doors) use electromagnetic locks to control the locking and unlocking of the platform doors, but there is a very prominent problem in the existing electromagnetic locks: as long as one of the left and right platform doors is closed first In place, the platform door on the other side has not been closed in place, the electromagnetic lock will still lock the closed platform door, but this cannot ensure that the other side door is also closed in place, this problem usually brings serious problems The consequences will affect the personal safety of passengers. Contents of the invention [0003] The purpose of the present invention is to overcome the existing problems in the prior art and provide a door lock and rail transit p...
