Abstract

The invention provides a locking device, a through channel and a rail vehicle. The locking device comprises a guide sliding groove. Each of the plurality of locking parts comprises a fixed locking unit and a movable locking unit; the movable locking unit is movably arranged on the guide sliding groove; the linkage rope is connected with the plurality of movable locking units; the linkage rope is suitable for driving the movable locking unit to move, so that the movable locking unit is matched with and separated from the fixed locking unit; when the movable locking unit is matched with the fixed locking unit, the movable locking unit and the fixed locking unit are locked in the extending direction of the through channel. The locking device provided by the invention can be used for quickly locking and unlocking the through channel, can also be used for the through channel with a special-shaped outline, and has a relatively large application range.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a locking device, a through channel and a rail vehicle. Background technique [0002] In the existing multi-group vehicles, adjacent carriages are connected through a through passage, and the connection between the through passage and the carriages is locked and unlocked by a locking mechanism. In the related art, the locking mechanism of the through-channel can only be used for the through-channel with a simple square profile, and cannot adapt to the contour of the through-channel with curvature or special shape. SUMMARY OF THE INVENTION [0003] In view of the above technical problems, the present invention provides a locking device for a through channel, which can quickly lock and unlock the through channel, and can also be used for a through channel with a special-shaped profile, which has a large application range. [0004] The concrete technical scheme of th...
