It is a kind of that bus is telescopic draws a structure
Technical field
The present invention relates to bus accessory field, be specially that a kind of bus is telescopic draws a structure.
Background technology
Bus is the important component part of city traffic, in bus, generally arrange overarm, overarm is hung with multiplely draw handle, for the passenger stood in bus, keeps stable to help passenger in the bus jolted.Prior art draws a structure simple, and setting height(from bottom) is fixed, if setting height(from bottom) is too high, for the passenger that height is not high, captures and draws comparatively inconvenience.
Summary of the invention
The object of this invention is to provide that a kind of bus is telescopic draws a structure, capture the problem of drawing inconvenience to solve the not high passenger of height.
In order to achieve the above object, the technical solution adopted in the present invention is:
It is a kind of that bus is telescopic draws a structure, include box body, it is characterized in that: in box body, be horizontally arranged with rotating shaft, and rotating shaft two ends are rotatably installed in box portion left respectively, in right sidewall, rotating shaft is vertically provided with a symmetrical left side, right side dish, left, rotating shaft between the dish of right side is wound with frenulum, a word through hole is had bottom described box body, frenulum band edge word through hole bottom box body passes box body, and frenulum band edge is connected with handle, left, right side dish and the rotating shaft separately between respective side box side wall are fixed with torsion spring respectively, and torsion spring two ends are separately fixed on side panel and side panel respective side box side wall, also laterally snap-fastener is slidably fitted with in sidewall on the left of described box body, described snap-fastener right-hand member forms land, and be connected with the extension spring be enclosed within by buckling between sidewall on the left of land and box body, described snap-fastener right-hand member is connected with crosses frenulum front and the connecting rod stretching to front between box body right sidewall and right side side panel, connecting rod right-hand member is connected with the wedge stretched between box body right sidewall and right side side panel, wedge is provided with the pressure head stretching to right side side panel, side panel corresponding pressure head position in described right side has the through hole passed through for pressure head, and pressure head is pressed on frenulum sidepiece by through hole.
Described a kind of bus is telescopic draws a structure, it is characterized in that: described box body top is connected with link, and link top is provided with a word through hole, and through there being suspender belt in a word through hole, and suspender belt two ends are provided with the thread gluing that can mutually bond.
In the present invention, wedge seaming chuck is pressed on frenulum sidepiece by right side side panel through hole at ordinary times, and frenulum cannot be rotated with rotating shaft, and the frenulum length above handle is constant.Press snap-fastener when needing, pressure head is departed from from frenulum sidepiece, and when applying pulling force to handle like this, frenulum variable-length is long, unclamps snap-fastener after reaching appropriate length, resets under being buckled in extension spring effect, makes pressure head again be pressed on frenulum sidepiece.Torsion spring between side panel and box side wall can, when pressing snap-fastener and do not apply pulling force on handle, make frenulum backrush to initial length.
The present invention can adjust the length of frenulum as required, can meet the requirement of different height passenger, improve the service quality of bus.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1.It is a kind of that bus is telescopic draws a structure, include box body 1, rotating shaft 2 is horizontally arranged with in box body 1, and rotating shaft 2 two ends are rotatably installed in box body 1 left side respectively, in right sidewall, rotating shaft 2 is vertically provided with a symmetrical left side, right side dish 3, 4, left, right side dish 3, rotating shaft 2 between 4 is wound with frenulum 5, a word through hole is had bottom box body 1, frenulum 5 band edge word through hole bottom box body 1 passes box body 1, and frenulum 5 band edge is connected with handle 6, left, right side dish 3, rotating shaft 2 between 4 and respective respective side box body 1 sidewall is fixed with torsion spring 7 respectively, and torsion spring 7 two ends are separately fixed on side panel and side panel respective side box body 1 sidewall, also laterally snap-fastener 8 is slidably fitted with in sidewall on the left of box body 1, snap-fastener 8 right-hand member forms land 9, and be connected with the extension spring 10 be enclosed within snap-fastener 8 between sidewall on the left of land 9 and box body 1, snap-fastener 8 right-hand member is connected with crosses frenulum 5 front and the connecting rod 11 stretching to front between box body 1 right sidewall and right side side panel 4, connecting rod 11 right-hand member is connected with the wedge 12 stretched between box body 1 right sidewall and right side side panel 4, wedge 12 is provided with the pressure head 13 stretching to right side side panel 4, side panel 4 corresponding pressure head 13 position, right side has the through hole passed through for pressure head 13, and pressure head 13 is pressed on frenulum 5 sidepiece by through hole.
Box body 1 top is connected with link 14, and link 14 top is provided with a word through hole, and through there being suspender belt 15 in a word through hole, and suspender belt 15 two ends are provided with the thread gluing 16 that can mutually bond.
