The invention discloses rail transit equipment and a locking and unlocking device for a through channel of the rail transit equipment. A locking mechanism or a lock seat mechanism can be connected by means of an existing connector or a vehicle body, a connector does not need to be arranged independently, parts are reduced, and the maintenance cost is decreased. Through the simple structural design, the maintenance and replacement cost is greatly reduced, and the service life of a product is prolonged; and the equipment is simple in manufacturing process and convenient to install, the phenomenon that the appearance of an existing frame body is limited is improved, adaptability is high, the connector is ensured to meet the requirements for safety and reliability of a vehicle in various motions, reliable connection of through channels with the complex appearance and the limited locking point position operation is achieved, marshalling time is greatly shortened, and operation efficiency is improved. The blank that a quick locking and unlocking device cannot be additionally arranged due to a special-shaped connecting body and a narrow space is filled, the application field is wide, the market potential is huge, and the economic benefit is considerable.
Description
technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a rail transit equipment and a locking and unlocking device for a passageway thereof. Background technique [0002] The through passage is an internal passage for passengers to walk freely from one compartment of the vehicle to another and make passengers feel safe and comfortable. The frame is one of the important components of the passage. The locking device is used for the main body of the passage and the two vehicles Or the connection between the through passages themselves plays the role of fixing the through passages. [0003] Most of the fast locking and unlocking in the existing rail vehicles are realized through the linkage of locking rods. It has high requirements on the shape and structure of the frame body, and this type of mechanism cannot be used in more complex or restricted through-channel structures. Therefore, there is an urgent need for a new t...
