Abstract

The invention provides a locking device, a through passage and a rail vehicle, the locking device includes a plurality of locking parts, each of which includes a fixed locking unit and a moving locking unit; a linkage rope connected to Multiple mobile locking units; the linkage rope is suitable for driving the mobile locking unit to move, so that the mobile locking unit cooperates with and disengages from the fixed locking unit; the distance adjustment part is set Between the moving locking unit and the linkage rope, in the extension direction of the linkage rope, the distance between two adjacent movement locking units can be adjusted; when the movement locking unit and When the fixed locking unit cooperates, the moving locking unit and the fixed locking unit are locked in the extending direction of the through channel. The locking device provided by the present invention can quickly lock and unlock the through channel, and can adjust the tension of the linkage rope, so that the locking device has a relatively high service life.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a locking device, a through passage and a rail vehicle. Background technique [0002] Existing multi-group vehicles connect adjacent carriages through through passages, and lock and unlock the connection between the passages and carriages through a locking mechanism. In the related art, after a period of use, the locking mechanism of the through channel will have a phenomenon of weakening or even failure of the locking effect, and cannot be used stably for a long time. Contents of the invention [0003] In view of the above technical problems, the present invention provides a locking device for the through channel, which can quickly lock and unlock the through channel, and can adjust the tension of the linkage rope, so that the locking device has a longer service life. [0004] Concrete technical scheme of the present invention is as follows: [0005] A locking d...
