Description

Diagonal plug machine drawing structure

Technical field

The utility model relates to a kind of plug machine drawing structure that is used for stopping sliding doors such as automobile, train and high speed passenger traffic vehicle, refers to a kind of diagonal plug machine drawing structure especially.

Background technology

As shown in Figure 4, what be applied at present that the plug pull-up structure of passenger's stopping sliding door of domestic passenger train adopts mainly is parallel four-bar linkage, it comprises optical axis 1 and the slide rail 2 that is fixed on the car body, connect a roll-type coaster 3 on the optical axis 1, be connected with an active side link 6 and a driven side link 7 by main hinge axle 4 with from hinge axis 5 on the roll-type coaster 3, initiatively side link 6 and driven side link 7 are connected with a connecting rod 10 by active hinge axis 8 and driven hinge axis 9, main hinge axle 4 and the distance between hinge axis 8 axial lines and equate with distance between driven hinge axis 9 axial lines initiatively from hinge axis 5, initiatively the distance between hinge axis 8 and the driven hinge axis 9 equates with main hinge axle 4 with from the distance between hinge axis 5 axial lines, so then by roll-type coaster 3, active side link 6, driven side link 7 and connecting rod 10 are formed a parallel four-bar linkage, connecting rod 10 is fixedlyed connected with door-plate 11, initiatively be connected with a roller 12 of being located in the slide rail 2 on the side link 6,2 fens segmental arc slide rails of slide rail and straightway slide rail two parts.When roller 12 when slide rail 2 segmental arcs move, then door-plate 11 and connecting rod 10 will curvedly leave or be moving near the Sai Laping of car body, when roller 12 when slide rail 2 straightways move, then door-plate 11 and connecting rod 10 carry out rectilinear motion.This shows that door-plate is always the translation mode in the process of closing the door.

Above-mentioned plug machine drawing structure, because door-plate need get around the secondary closed edge side wall of car body in Sai La closes the door process, thereby the distance between secondary closed edge door-plate side and the car body door opening must design greater than the spacing between main closed edge door-plate side and the car body door opening, therefore the obvious aesthetic property that must reduce door system.

Chinese Railway passenger vehicle speed improves constantly, for prevent train at meeting and when coming in and going out the tunnel lateral gas be subjected to squeeze supercharging and cause derail, bullet train all adopts the arc car body.When above-mentioned plug machine drawing structure is used for the arc car body, owing to the reason of making or assembling, tend to the situation that occurs misplacing up and down between door-plate camber line and the car body sidewall camber line, so that on a certain height of door-plate and the spacing between the car body sidewall reduce, the place that the door-plate pair is closed the avris corresponding height in the process of closing the door is easy to scratch car body sidewall like this.

This creator actively makes great efforts research, through research and development with great concentration, invents out the utility model of true tool practical effect and industrial utilization finally.

Summary of the invention
