Embodiment Construction

[0022] Such as Figure 1~10 As shown, an emergency unlocking device for a rail vehicle partition wall includes an operating assembly and an emergency shift block assembly. The operating assembly includes a handle 1 and a lever 3. The lever 3 is fixed on the partition wall through a rotating pin, and the handle 1 is arranged on the lever The labor-saving end of 3, the other end of lever 3 is connected with stopper 4 by stay cord 2. The handle is located on the outside of the partition door, and other parts of the emergency unlocking device for the rail vehicle partition are located on the inside of the partition.

[0023] The emergency block assembly includes a fixed shaft 7, a lock block 6 and a stopper 4, the stopper 4 and the lock block 6 are set on the fixed shaft 7, the stopper 4 and the fixed shaft 7 slide up and down through the key and the keyway, and the key and the keyway The key grooves are arranged on the fixed shaft 7 and the stopper 4 respectively, the lock stopp...

Abstract

The invention relates to an emergency unlocking device for railway vehicle partition walls. The emergency unlocking device comprises an operation assembly and an emergency shift block assembly. A stop gear and a lock gear of the emergency shift block assembly are sleeved on a stationery shaft, the stop gear and the stationery shaft are matched in a vertical linear sliding mode, the lock gear is matched with the stationery shaft in a rotary mode, and the stop gear is pressed tightly on the lock gear through an elastic element. A stop block structure is arranged on the lock gear, and a spiral curved surface for converting linear return motion of the stop gear under the action of the elastic element into a rotary return motion of the lock gear is arranged on a contact end surface of the lock gear. A limit protruding block is arranged on one side at a high end of the spiral curved surface, and a limit groove is arranged on one side at a low end of the spiral curved surface. A contact end surface structure of the stop gear and a contact end surface structure of the lock gear are complementary and matched. The emergency unlocking device for railway vehicle partition walls has the advantage that locking of the lock gear can be removed manually in emergency situations of no electric power or aerodynamic force of railway vehicles, the lock gear can rotate, blocking of the lock gear to a lock bolt on a partition wall door is removed, and accordingly, the partition wall door can be opened automatically.

Description

technical field [0001] The invention relates to an emergency unlocking device for a rail vehicle partition wall. Background technique [0002] At present, there is no emergency unlocking device for passengers to open the partition wall and automatically reset the partition wall behind the driver's cab of rail vehicles without electricity and pneumatic power. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an emergency unlocking device for a rail vehicle partition wall, in an emergency, passengers can quickly open the partition wall door on the partition wall behind the rail vehicle driver's cab without electricity and pneumatic power, Passengers can escape through the escape door at the front of the driver's cab. [0004] The technical solution adopted by the present invention to solve the technical problem is: an emergency unlocking device for a rail vehicle partition wall, including an operation assembly and a...
