Abstract

The utility model relates to a folding bicycle. The utility model is mainly provided to enable the bicycle to be convenient to fold, enable the volume of the bicycle to become smaller after the bicycle is folded and enable the bicycle to be more convenient to carry. Two folding shafts are mainly arranged on the crossbeam of the bicycle, one folding shaft is folded in a longitudinal way, and the other folding shaft is folded in a transverse way. A folding point is arranged on the front fork of the bicycle and under a saddle respectively. Because the longitudinal length of the bicycle is folded three times, so the volume of the bicycle is smaller. Besides, the utility model can be pulled during walking after folded, and the utility model can be used for carrying objects.

Description

Folding bicycle

The utility model relates to a kind of energy folding of bicycle.

Existing folding bicycle generally has only a fold line (point), takes mode folding or that peg graft to connect in burst, and problem is that volume is still bigger after folding, and inconvenience is carried.

The purpose of this utility model is that a kind of volume after folding of design is littler, the folding bicycle of being more convenient for carrying; And folding back two-wheeled is parallel and together, can haul walking on the ground.

The purpose of this utility model is achieved in that bicycle comprises parts such as wheel, vehicle frame, pedal, front fork, saddle, the utility model is to establish folding axle 1 and folding axle 2 on the crossbeam (longeron) at bicycle, make a folding axle longitudinal folding on folding direction, another folding axle is laterally folded; Establish break 3 on the car front fork, break 4 is established in the saddle below.Break 3 and break 4 can be adorned the folding axle, and the mode that also can take to peg graft connects.

According to prior art, the folding axle has a variety of method for makings, and provide a kind of new design here: establish axle 6 in a side of folding 5, opposite side is established cotter way 7, each fixing some pages of folding on the beam on folding axle both sides, the folding on two side bars fixes by axle 6, and the cotter way of both sides folding coincides together, fix by pin 8, pin 8 is stuck in the cotter way by the spring tension, establishes pin rod 9 on the pin, to sell in cotter way with hand pin rod rear end and to pull out, just can fold.

The utility model has the advantages that: because two folding axles are arranged on the longeron, realized that on the length of car three foldings are folding, front fork and saddle also can fold or insert and contract, so volume after folding is littler, be more convenient for carrying, and folding back can be carried thing on the back above because two-wheeled is parallel and together, can haul walking on the ground.

Accompanying drawing 1 is an overall schematic of the present utility model, and among the figure: 1, the folding axle 1; 2, the folding axle 2; 3, break 3; 4, break 4.

Accompanying drawing 2 is folding axle scheme drawings, among the figure: 5, folding; 6, axle; 7, cotter way; 8, pin; 9, pin rod; 10, beam.

Embodiment: I get a single-beam bicycle, and at Liang Shangshe folding axle 1 and folding axle 2, folding axle 1 is laterally folded, and folding axle 2 is longitudinal folding, and the position of folding axle 2 on beam is corresponding with the chain cover front end; The break 4 of break 3 on the car front fork and saddle below also all is the folding axle of dress.

Claims

1, a kind of folding bicycle, it comprises parts such as wheel, vehicle frame, pedal, front fork, saddle, it is characterized in that establishing on the crossbeam of bicycle folding axle [1] and folding axle [2], makes a folding axle longitudinal folding on folding direction, another folding axle is laterally folded; Establish break [3] on the car front fork, break [4] is established in the saddle below.

2, according to the said folding bicycle of claim 1, the composition that it is characterized in that rolling over axle is to establish axle [6] in a side of folding [5], opposite side is established cotter way [7], each fixing some pages of folding on the beam on folding axle both sides, the folding on two side bars fixes by axle 6, and the cotter way of both sides folding coincides together, fix by pin 8, pin 8 is stuck in the cotter way by the spring tension, establishes pin rod 9 on the pin.
