Description

Folding Bicycle

The utility model relates to a kind of vehicle, relates to a kind of Folding Bicycle particularly.

Existing bicycle by component set-ups such as tap, vehicle frame, pedal, front and back wheels, is a kind of vehicle that present people use always mainly.But existing bicycle volume is big, and is quite heavy again, goes out to carry extremely inconvenient.In addition, the people who lives upstairs brings up to bicycle and moves down also quite effort.

It is a kind of simple to operate that the purpose of this utility model is to provide, and driving stability can fold, and makes to carry, carry bicycle more easily.

To achieve these goals, Folding Bicycle of the present utility model mainly is made up of tap, vehicle frame, pedal, front and back wheel, all be equipped with turning joint at tap, big thick stick, pedal, seat stool place, this joint is made up of a spill ball and socket joint and a convex ball and socket joint, is flexible connection between spill ball and socket joint and the convex ball and socket joint; Also be provided with sleeve pipe, spring and back-up ring successively in convex ball and socket joint periphery.

Because Folding Bicycle tap of the present utility model, big thick stick, pedal, seat stool place are equipped with turning joint, thereby can make bicycle folding on three directions of length, the bicycle volume of folding up dwindles greatly, can carry when people go out, bring many convenience for the people who gos out outside.The bicycle that additional folding is got up is put at home can not occupy great space, and the people who lives upstairs removes on the car also convenient downstairs.Because joint is provided with sleeve pipe and spring, after bicycle strutted, sleeve pipe was tightly fixed two concave, convex shape ball and socket joints, is unlikely under steam and waves instability again.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the utility model Folding Bicycle structural representation;

Fig. 2 is the cutaway view in Folding Bicycle shown in Figure 1 joint.

As seen from Figure 1, Folding Bicycle of the present utility model mainly is made up of tap, vehicle frame, pedal, front and back wheel, be provided with joint 5 on left and right sides handle leading 1 and the straight thick stick, front and back wheel can overlap when realizing bicycle folding, volume is more compact, bicycle thick stick is designed to horizontal, keeps at a certain distance away on the big thick stick 2 of horizontal and be provided with two joints 5, on the bicycle pedal 3 and below of bicycle saddle 4 is equipped with joint 5.Again by bicycle joint cutaway view shown in Figure 2 as seen, joint 5 is made up of a spill ball and socket joint 6 and a convex ball and socket joint 7, flexibly connects by bolt 11, and when two ball and socket joints 6,7 coupled together, its male and fomale(M﹠F) coincide mutually.Be provided with a moving casing 8 in the periphery of convex ball and socket joint 7, bolt 11 blocks an end of sleeve pipe 8, and the other end of sleeve pipe 8 is a spring 9, and the other end of spring 9 is provided with a fixing back-up ring 10.

During bicycle folding, the end of sleeve pipe 8 to spring 9 advanced, can rotate, can realize the folding of bicycle each several part until joint 5.Strut when using, rotate the joint of each several part, sleeve pipe 8 tightly entangles concave, convex ball and socket joint 6,7 under the effect of spring 9 thrusts, and bicycle becomes integral body immediately, just can travel.

In order to increase the holding capacity of tap and big thick stick, two parallel straight thick sticks of design between the handle of tap and front fork, the symmetrical joint of difference fit on, big thick stick also can be designed to two big thick sticks of level, two symmetrical joints of difference fit on, in addition, tap is folding for convenience, can adopt wire digging line formula brake modes.Equally, the connection between the machicolated form ball and socket joint is not limited to bolted connection, also can adopt other movable connection mode, connects as rivet.

Folding Bicycle of the present utility model also is furnished with folding shelf, and these shelf are connected with the shelf of bicycle by hinge, when not using with it to folding up.
