Abstract

The invention discloses a door lock device for a safety door system and the safety door system. The safety door system is provided with an inlet and outlet port and comprises a fixing door framework and a sliding door for opening and closing the inlet and outlet port. The door lock device has a locking state and an unlocking state. The door lock device comprises a locking mechanism arranged on thefixing door frame. The locking mechanism comprises a lock body, a lock disc assembly and a locking piece, the lock body is connected to the fixing door frame, the lock disc assembly is rotationally arranged on the lock body, the locking piece is movably arranged on the lock body, the moving direction of the locking piece is perpendicular to the rotation axis of the lock disc assembly, and a firstmatching part and a second matching part are formed on the periphery wall of the lock disc assembly and arranged in the circumferential direction of the lock disc assembly in a spaced manner in the circumferential direction. The door lock device is suitable for a door touch piece matched with the locking mechanism, and the door touch piece is arranged on the sliding door. According to the door lock device, the thickness is small, and locking mechanism maintenance and replacement are convenient to achieve.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a door lock device and a safety door system for a safety door system. Background technique [0002] Safety doors are used to isolate rail transit vehicles from the platform side, which has a great impact on transportation safety and transportation efficiency. The safety door with high safety, high reliability, long life and convenient maintenance is an effective guarantee for the safety and efficiency of rail transportation. The door lock device is the core functional part of the safety door, and its structural design determines the safety, reliability and maintainability of the safety door. [0003] However, the thickness of the door lock device in the related art is large, and it is necessary to reserve a large installation space in the thickness direction of the fixed door frame to install the door lock device, which is not conducive to the optimal design of the safety d...
