Abstract
The utility model discloses a resetting-mechanism of a three-member blocking door, and the technical problems which need solving are to enhance the flexibility when the three-member blocking door pushes a rotary rod and to increase comfort and safety of using the three-member blocking door. For solving the above technical problems, the following technical proposal is adopted: a resetting-mechanism of the three-member blocking door comprises a blocking door body and the rotary rod which is connected on the blocking door body by an axial center, the rear portion of the axial center of the rotary rod has the resetting-mechanism which comprises a plastic railway, the outside of the plastic railway has a large connecting rod and a small connecting rod, and a damper is arranged between the large connecting rod and the small connecting rod. Compared with the prior art, an air spring, the damper and a curved plastic movement railway are engaged and combined to form the resetting-mechanism, the three-member blocking door has good flexibility when pushing the rotary rod, and the operation and the use are comfortable and safe.
Description
Technical field
The utility model relates to a kind of resetting-mechanism of three-bar blocking door, particularly a kind of three-bar blocking door that is used for the automatic ticket checking of track traffic and public place.
Background technology
Construction of Urban Rail Traffic is all being carried out in domestic and international many cities at present, and extensively adopt rail traffic ticket automatic selling and checking (AFC) system to realize the automation and the informationization of rail transportation operation, automatic ticket checker is that one of key equipment in ticket checking (AFC) the AFC system is sold in track traffic, and the core component of automatic ticket checker is to be used to control the blocking mechanism that the passenger comes in and goes out.Wherein, the blocking mechanism (be equivalent to door function) that is applied to automatic ticket checker has two kinds of patterns: three bars resistance shelves door (abroad also cry three rollers resistance shelves, three bar bull stick doors) and scissors door.Three-bar blocking door is as blocking mechanism with rotating pin, being different from the scissors door has on-off action, and security performance is better, and passage rate is higher, can prevent effectively that personnel from trailing enters, and is adapted to places such as passenger flow is big, the passenger is relatively more crowded track traffic, bus rapid transit, stadiums inlet.
Resetting-mechanism is the important component part in the three-bar blocking door, be used for bull stick automatically reseting after rotation, three-bar blocking door in the practical application still exists following shortcoming: structure is single, flexible relatively poor, thereby cause rotate and when resetting impact force too big, safety in utilization is lower, and hommization is provided with poor.
Summary of the invention
The purpose of this utility model provides a kind of resetting-mechanism of three-bar blocking door, and the technical problem that solve is the pliability when improving three-bar blocking door promotion bull stick, improves a comfort level and a safety that three bars resistance shelves door uses.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of resetting-mechanism of three-bar blocking door, comprise barrier door body, bull stick, described bull stick is connected on the barrier door body by the axle center, the rear portion, axle center of described bull stick is provided with resetting-mechanism, described resetting-mechanism comprises the plastic cement track, and described plastic cement track is provided with big connecting rod and small rod outward, is provided with damper between described big connecting rod and the small rod.
Plastic cement track of the present utility model is the rear side that central point is arranged on the barrier door body with the axle center, one end of described big connecting rod is connected outside the plastic cement track by splined shaft, the other end of described big connecting rod connects an end of big bearing, the other end of described big bearing is coupling on the barrier door body, and described small rod is coupling on the barrier door body.
Small rod of the present utility model is respectively equipped with roller with the end that barrier door body, big connecting rod are connected with splined shaft.
Be provided with air spring in the big bearing of the present utility model.
The upper end of big bearing of the present utility model is provided with extension spring, and an end of described extension spring connects big bearing, and the other end is connected on the barrier door body.
Plastic cement track of the present utility model is one three a trouble camber structure.
Three trouble angles of plastic cement track of the present utility model are mutually 120 degree.
The utility model compared with prior art adopts air spring, damper to cooperate with curved surface plastic cement tracks and forms resetting-mechanism, makes three-bar blocking door have good flexible when being pushed bull stick, and manipulates comfortable, safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the resetting-mechanism of three-bar blocking door comprises barrier door body 11 and bull stick 10, and barrier door body 11 connects bull stick 10 by axle center 12, and the rear portion in axle center 12 is provided with novel resetting mechanism 13.This resetting-mechanism 13 comprises with axle center 12 being the plastic cement track 1 of central point, and described plastic cement track 1 is one three a trouble camber structure, is mutually 120 degree angles and smooth continuous circular curve constitutes by three, and its three summits are three zero points that reset.Plastic cement track 1 outer big connecting rod 8 and the small rod 3 of being provided with, be provided with damper 7 between big connecting rod 8 and the small rod 3, one end of big connecting rod 8 is connected outside the plastic cement track 1 by splined shaft 9, the other end connects big bearing 6, big connecting rod 8 is hinged with big bearing 6, and the other end of big bearing 6 is coupling on barrier door body 11.Be provided with damper 7 at big connecting rod 8 with the next door that big bearing 6 is connected an end, an end of damper 7 is connected on the big connecting rod 8, and the other end is connected on the small rod 3, and small rod 3 is hinged with damper 7.The other end of small rod 3 is coupling on barrier door body 11, is respectively equipped with roller 2 on small rod 3 and the position that barrier door body 11 is coupling with on splined shaft 9 and the position that big connecting rod 8 is connected, and roller 2 slides on the outside of plastic cement track 1.The utility model is being provided with air spring 5 in big bearing 6, be provided with extension spring 4 on big bearing 6 and a end that barrier door body 11 is connected, and an end of extension spring 4 is connected on the big bearing 6, and the other end is connected on the barrier door body 11.
When the utility model uses, when the people promotes bull stick 10, bull stick 10 drives traffic cycle and rotates by the plastic cement track 1 that splined shaft 9 is attached thereto, at this moment air spring 5 and damper 7 are all stressed is elongated, when bull stick 10 movement angles surpass or less than 120 when spending, because air spring 5 effects, resetting-mechanism 13 all will drive bull stick 10 and reset to the zero point that resets of plastic cement track 1; In whole motion process, roller 2 on big connecting rod 8 and the small rod 3 all remains on operation on the smooth plastic cement track 1, because the cushioning effect of the damper 7 that links to each other with small rod 3 with big connecting rod 8 is arranged, make that the whole course of action of bull stick 10 is all very steady, impact force is low, and noise is little and use sense of touch better.
