Description

Collapsible bicycle

The utility model relates to a kind of Foldable bicycle.

Bicycle be use in people's daily life at most, the vehicle the most widely, but its volume is not big, and is portable and park, and brings inconvenience for people's daily life.The design-calculated folding bicycle also can not change bulky defect after folding at present.

The purpose of this utility model provides a kind of minimum Collapsible bicycle that takes up space behind bicycle folding.

For achieving the above object, solution of the present utility model is: Collapsible bicycle, it comprises front and back wheel, front and back wheel support, Che Gang, chain disc carrier, seat board support, foot-operated, and the car thick stick (1) that can embed each other is articulated and connected with rear wheel support (2), and dowel bolt (3) is equipped with in the junction.

Because car thick stick and rear wheel support can embed for folding back 180 ° each other, make the fold thicknesses of bicycle be no more than 150mm, reduced bicycle folding after institute take up space.

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Fig. 2 is car thick stick and rear wheel support structural representation

Fig. 3 is the birds-eye view of Fig. 2

Fig. 4 is the front-wheel support structural representation

Fig. 5 is a sliding sleeve containment structure scheme drawing

Fig. 6 is the front elevation of Fig. 5

Fig. 7 is that pin turns and ride structural representation

Fig. 8 is that pin turns structural representation

See Fig. 2, Fig. 3: car thick stick 1 is hollow tubular, and rear wheel support 2 is a C shape tubing, and car thick stick 1 is articulated and connected with rear wheel support 2, and the hinged place is provided with dowel bolt 3, by the place of being articulated and connected car thick stick 1, rear wheel support 2 is embedded each other after folding 180 °.

See Fig. 1, Fig. 2, Fig. 3, the top of car thick stick 1 is provided with seat board bearing 4, seat board pole 5, bolt of rear end plate 6, seat board bearing 4 is articulated and connected with seat board pole 5, the below of car thick stick 1 is provided with chain drum bearing 7, chain drum pole 8, binding bolt 9, chain drum bearing 7 is articulated and connected with chain drum pole 8, and the described place that is articulated and connected is fixing by binding bolt 8,9.

See Fig. 1, Fig. 4, Fig. 5, Fig. 6, front-wheel support 10 is the single armed doublejointed, constitute by axletree frame 11, lower fulcrum bar 13, upper rack posts 12 3 parts, axletree frame 11 is articulated and connected with lower fulcrum bar 13, fixing by spring holder 14, upper rack posts 12 is articulated and connected with lower fulcrum bar 13, and fixing by spring holder 15, upper rack posts 12 tops are provided with sliding sleeve 16.Sliding sleeve 16 is contained on the sliding sleeve axle 17, and sliding sleeve axle 17 is fixed on the sliding sleeve shell 18, and sliding sleeve shell 18 is fixed on the handlebar support 23, and dowel bolt 19 is housed on sliding sleeve shell 18.

See Fig. 7, Fig. 8, pin turns 20, foot-operated 21 be articulated and connected, and is provided with spring holder 22, foot-operated 21 and can turns 20 parallel or embed pin and turn in 20 with pin after folding.

The folding bicycle that the utility model proposes is compared with existing design-calculated folding bicycle, all is provided with hinge linkage in burst, and car thick stick and rear wheel support can embed after folding 180 ° by being articulated and connected each other.Make the folding back of this folding bicycle compact conformation, folding convenient, volume little.Thickness is no more than 150mm, and diameter is a wheel diameter.

Further specify principle of work of the present utility model below in conjunction with accompanying drawing.

Press Fig. 1, shown in Figure 2, unclamp binding bolt 6, seat board pole 5 is folding to car thick stick 1 the place ahead, unclamp and regulate binding bolt 9 that chain drum is propped up thick stick 8 is folding to car thick stick 1 the place ahead.

Press Fig. 1, shown in Figure 3, unclamp binding bolt 3.With folding 180 ° counter clockwise on car thick stick 1, car thick stick 1 is embedded in the rear wheel support 2.

Press Fig. 7, shown in Figure 8, take out out spring holder 22.To ride the folding 90 ° of embedding pin of 21 cws turns in 20.

Press Fig. 1, shown in Figure 4, take out out two

joint spring holders

14,15 of front-wheel support 10, front wheel spindle support 11 inhours are folding, again that lower fulcrum bar 13 inhours are folding.

Press Fig. 1, Fig. 5, shown in Figure 6, unclamp binding bolt 19 and promote sliding sleeve 16 to the right, make front-wheel be parallel to trailing wheel.Adjust the front-wheel center, front-wheel is overlapped with the trailing wheel axis, it is folding promptly to finish this utility model.Bicycle maximum gauge after folding is a wheel diameter, and maximum ga(u)ge is no more than 150mm.

Undertaken by the said process reversing sense during expansion.
