Problems solved by technology
It has high requirements on the shape of the frame, and the structure of the through channel with a complicated frame or limited operation cannot use this kind of locking rod linkage mechanism. Therefore, a new type of locking mechanism that meets the requirements of various working conditions is urgently needed. For through-channels with complex shapes and limited manipulation of locking point positions

The invention belongs to the technical field of rail transit equipment, and relates to a locking and unlocking device for through channels. The mounting and operating modes are changed, locking components and lock bracket components mounted on different connecting bodies can be remotely operated, a spring bolt can also be directly operated, and when the locking and unlocking device is used indoors, after locking operation is finished, a cover plate is pressed into a locking hole, a polygonal protrusion on the rear portion of the cover plate is matched with a polygonal core hole of the spring bolt, the specific position of the spring bolt can be transmitted according to a marking hole formed in a head of the cover plate, and the locking condition is judged. The locking and unlocking device for the through channels is simple in manufacturing process and convenient to install, the phenomenon that the appearance of a frame in the prior art is limited is improved, adaptability is high, it is guaranteed that the connecting bodies can meet the requirements for safety and reliability of a vehicle during various motions, reliable connection of through channels complex in appearance and limited in locking point position operation is achieved, marshalling time is shortened, operation efficiency is improved, and the blank that a quick locking and unlocking device cannot be additionally arranged due to a special-shaped connector and a narrow space is filled.
Description
Technical field: [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to a locking and unlocking device for a passage, which can be quickly unlocked and locked at both ends. 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 existing rail vehicles is achieved through the linkage of locking rods, for example: a locking mechanism disclosed in Chinese patent 201810923616.4, including a locking rod, a lock seat and several locking rod clips, the lock The rod includes several sub-rods, and e...
