Description

technical field

[0001] The present invention relates to a spiral double rocker guide rod groove type cam combination space mechanism for a plug door, which relates to a plug seal opening and closing mechanism for a plug door of a vehicle, in particular to a screw for a plug door of a high-speed rail or other rail vehicles. Double rocker guide rod cam combined space mechanism. Background technique

[0002] Rail vehicle plug doors generally have two or one leaves. When there are two leaves, on the one hand, it is necessary to realize the opening and closing movement of the two leaves of the doors that are opened and closed. The inner door leaf pulls movement to ensure a good sealing effect after closing the door; when it is one leaf, the above-mentioned plug seal opening and closing movement is also realized, only to realize the single opening and single closing of one leaf.

[0003] In order to realize the function of opening and closing the sliding door, the existing slidin...
