BUILT-IN PLUG-PULL DOOR DEVICE FOR TRACK VEHICLE

摘要

Disclosed in the present invention is a built-in plug-pull door device for a track vehicle, which comprises a control mechanism (1), a driving mechanism(2), a bearing mechanism(3), a pressing mechanism(4), a guiding slide groove(5) and a door leaf (7). Said bearing mechanism (3) comprises two guide rod column (10), two sleeves (11), a connecting rod (12), a sliding block (13) and a guide wheel (14). Said control mechanism (1) is respectively connected to the driving mechanism (2) and the pressing mechanism (4). The device combines the advantages of a swing-outward plug-pull door and a built-in side pull door, and solves the problem of uneven appearance of the built-in side pull door via plug-pull movement and thereby reducing the effect of high-speed pressure wave on the door leaf and reducing the noise produced by high-speed travel. The width of the vehicle body is 140mm more than that of the vehicle which is provided with the swing-outward plug-pull door. When the plug-pull process of the door leaf ends, the door leaf is pressed on the vehicle body, which limits entirely the possibility that the door leaf might fall off the vehicle outward. The safety and the seal reliability can be improved.
