Vehicle emergency evacuation door lock and train thereof

Abstract

The invention relates to the technical field of trains, and discloses a vehicle emergency evacuation door lock and a train thereof. The vehicle emergency evacuation door lock comprises a locking mechanism arranged on an evacuation door body and at least two zip-fastener mechanisms, wherein the zip-fastener mechanisms are distributed on one side or two sides of the door body in the height direction, and a vehicle body is provided with fixing columns at the corresponding positions of the zip-fastener mechanisms; each zip-fastener mechanism comprises a lock hook provided with a hook groove matched with the fixing column, the locking mechanism comprises a plurality of pull lines connected with the zip-fastener mechanism in a one-to-one correspondence mode, and the locking mechanism controls the lock hook to rotate by pulling the pull lines to be embedded into or disengaged from the fixing column so as to close or open the evacuation door. A zip-fastener shaft seat is connected with the lock hook through the pull wire, the pull wire drives the lock hook to be disengaged from or hooked into a limiting column by rotating the zip-fastener shaft seat, and rapid opening and closing of the emergency door are achieved. According to the lever principle, a U-shaped handle and a push block are arranged at the position of the locking mechanism, an arc-shaped connecting rod of the U-shaped handle drives the push block to easily achieve rotation of the zip-fastener shaft seat, time and labor are saved, and conditions are further provided for rapid opening and closing of the emergency door.

Description

technical field [0001] The invention relates to the technical field of vehicle evacuation door design, in particular to a vehicle emergency evacuation door lock and a train thereof. Background technique [0002] During the normal operation of the train, it is necessary to prevent the emergency evacuation door from suddenly opening to cause a safety hazard, and in an emergency, the evacuation door needs to be opened quickly and conveniently, so that passengers can leave the train safely and orderly. [0003] At present, the evacuation doors on the market are not equipped with easy-to-operate handles on the doors, and it is very laborious to open and close the doors every time. In an emergency, the evacuation doors cannot be opened quickly; in addition, the evacuation doors are basically not equipped to prevent misuse during train operation. There is a great potential safety hazard. Even if some evacuation doors are equipped with a locking mechanism, the set locking mechanism ...

Problems solved by technology

[0003] At present, the evacuation doors on the market are not equipped with easy-to-operate handles on the doors, and it is very laborious to open and close the doors every time. In an emergency, the evacuation doors cannot be opened quickly; in addition, the evacuation doors are basically not equipped to prevent misuse during train operation. There is a great potential safety hazard. Even if some evacuation doors are equipped with a locking mechanism, the set locking mechanism is cumbersome to operate when opening and closing the door, and it is still impossible to quickly open the evacuation door in an emergency.
