Abstract
The utility model discloses a rear supporting pillar for bicycles, composed of a base, a supporting pillar and a locking spring. The base adopts aluminium alloy for extrusion forming, and the inner side of the upper part of the base is provided with a horizontal convex slot or an incline convex slot. The supporting pillar is movably supported in a concave slot arranged at the lower part of the base, and the inner-covered locking spring is arranged between the upper part of the concave slot of the base and the top part of the supporting part. The utility model has the advantages of compact integral structure, high strength, beautiful appearance, quick installation and reliable use. The problem that the locking spring falls out is completely solved.
Description
The utility model relates to the aluminum alloy back prop of bicycle assembly parts technical field, particularly a kind of bicycle use.
Existing bicycle back prop mostly is the ferrous material manufacturing, is installed on rear axis or the back chain stay, for preventing that back prop from centering on attachment point and rotating, must be fixed with a connection piece between chain stay or the rear stays behind back prop upper end and the bicycle.This kind back prop, Heavy Weight, perishable get rusty, stop support reliability locking spring relatively poor and pillar and expose, come off easily and influence the car load in-use performance.
The purpose of this utility model is to provide a kind of back prop of bicycle use, and it can not only make the locking spring not expose, and can not come off, and simple installation, use is reliably.
The purpose of this utility model is achieved in that a kind of back prop of bicycle use, comprises pedestal, pillar and locking spring, and described pedestal adopts aluminium alloy extruded moulding; The pedestal upper inner is provided with horizontal tongue or oblique tongue, has mounting hole at the tongue middle part; The pedestal bottom is provided with groove, pillar freely-movable bearing in groove, the locking spring is housed between post top portion and the groove top, forms a kind of enwraped type structure.
According to back fork of bicycle sheet grooved shape difference, be two kinds of fluting fork sheets before fluting fork sheet and the tilting after the level, can adopt respectively and of the present utility modelly be with horizontal tongue aluminum alloy back prop and be with oblique tongue aluminum alloy back prop.
The utility model compared with prior art has following advantage:
(1) adopts parts such as pedestal that aluminum alloy extrusion section bar makes, intensity height, compact conformation, aesthetic in appearance, withstanding corrosion, locking spring to adopt the enwraped type structure, do not have the locking spring problem that comes off.
(2) the aluminum alloy back prop that will have a tongue directly is contained in the hind axle hold down groove of back fork of bicycle sheet, so just must not increase any attaching parts again, and can prevent the rotation of back prop reliably around the hind axle core, therefore, make this back prop quick for installation, easy, use reliable.
(3) center that installs and fixes of this back prop overlaps with the hind axle center fully, has saved other fastener, attaching parts, has saved the car load assembly time, and has had comformability widely.
Fig. 1 is a kind of structural representation during with horizontal tongue aluminum alloy back prop holding state of the utility model.
Fig. 2 is the left view of Fig. 1.
Structural representation when Fig. 3 is an aluminum alloy back prop sweepback state shown in Figure 1.
Fig. 4 is the pedestal front view of the horizontal tongue of the utility model band.
Fig. 5 is the pedestal front view of the utility model band inclination tongue.
By following embodiment the utility model is further elaborated.
Referring to Fig. 1-shown in Figure 4, present embodiment is a kind of aluminum alloy back prop with horizontal tongue, and it is made up of pedestal 1, pillar 3, locking spring 2.Pedestal 1 upper inner is provided with horizontal tongue 4, has mounting hole 5 at these tongue 4 middle parts, and pedestal 1 bottom is provided with groove 6, pillar 3 tops insert in this groove 6 and by rotating shaft 7 freely-movable bearings on groove 6 inside and outside sidewalls.Pillar 3 tops are provided with small boss, and top of chamber also is provided with little concave station in the base recess 6, and locking spring 2 just is contained between above-mentioned two little, and locking spring 2 can make pillar 3 obtain the locking of " support " or " sweepback " two states.The foregoing description is applicable to the bicycle of fluting fork sheet after the level.
During installation, bicycle rear shaft one side nut is unclamped, the mounting hole 5 of this back prop is inserted in the groove of fluting fork sheet after the horizontal tongue 4 embedding levels of hind axle and pedestal 1, and then, the nut and tightening of packing on hind axle is promptly finished the assembly work of back prop.
When fluting was pitched the sheet bicycle before being used for tilting, its pedestal 1 should be with oblique tongue 8, and shape is seen shown in Figure 5.
Claims (1)
1, a kind of back prop of bicycle use, comprise pedestal, pillar and locking spring, it is characterized in that: described pedestal adopts aluminium alloy extruded moulding; The pedestal upper inner is provided with horizontal tongue or oblique tongue, has mounting hole at the tongue middle part; The pedestal bottom is provided with groove, pillar freely-movable bearing and in groove, between post top portion and the groove top locking spring is housed.
