Description

Half-packaging folding bicycle

Technical field

The present invention relates to a kind of bicycle, especially a kind of half-packaging folding bicycle.

Background technology

In the prior art, folding bicycle generally all is folding around the cycle frame middle part, and folding back two-wheeled is overlapping substantially, parallel.Use the prior art folding of bicycle, carry also inconvenient in fact, its reason is: because wheel is generally all bigger, volume after folding is still bigger, and generally all do not wrap up, all metal partss expose, and the portable or shoulder back of the body is not suitable for really, not only damage oneself easily, also hinder others easily.If draw row or implementation, then existing folded bicycle is because of being subjected to the restriction of folding mode, and it draws row or carries out poor-performing.

Summary of the invention

The objective of the invention is: a kind of half-packaging folding bicycle is provided, solves the problem that the existing inconvenience of present folding bicycle is carried out, carried.

Technical scheme of the present invention is: half-packaging folding bicycle comprises the preceding pipe of vehicle frame, seat tube, handlebar, folding pedals, saddle, seatpillar, front-wheel, trailing wheel etc.; Be provided with X type vehicle frame between pipe and the seat tube and be responsible for before vehicle frame, X type vehicle frame is responsible for by A pipe and B pipe and is constituted; Four ends at A pipe and B pipe respectively are provided with a termination hinge, and four termination hinges are flexible connection with A pipe and B pipe, and wherein two termination hinges and vehicle frame are preceding manages to captiveing joint, and two other termination hinge and seat tube are for captiveing joint; On A pipe and B pipe, also respectively be provided with a middle hinge; The A pipe is made as the Y shape, is made up of one section bassoon and two sections tubules, and folding back two sections tubules can be managed overlappingly with B, do not take up space in addition; On the point of crossing of A pipe and B pipe, be provided with turning cylinder; On the A pipe, also be provided with the secondary transmission and acceleration chain wheel of forming by crank and chain-wheel and accelerating pulley, make that speed was close with big wheel bicycle when this kind small-wheel bicycle was ridden; On seat tube, be fixed with half bag device, partly wrapping device is made up of urceolus, mandrel, spring, infantees, groove, one end of spring and an end of infantees all are fixed on the mandrel, the other end of spring is fixed on the urceolus, the groove that the other end of infantees passes on the urceolus is exposed, spring is opposite with the hand of rotation of infantees, spring can be screwed by mandrel when pulling out infantees, infantees can be taken in urceolus by mandrel when spring returns pine.

The invention has the advantages that:

(1) method for folding is simple, fast, easily, half-lap particularly, and the mechanism that does not need to unclamp quick detach and so on directly firmly gets final product.

(2) after the half-lap, carry out can resembling when folding; Simultaneously, because the deflation of X type vehicle frame is drawn close after the half-lap, car load becomes Chui Zhi Xi Bales shape, and floor area is little, and complete folding back floor area does not increase.

(3) can partly wrap up after half-lap or complete the folding, be not easy to damage oneself, also be not easy to hinder others, it is convenient especially to carry, and really is suitable for come in and go out subway, automobile, supermarket or the like.

Among the figure: 1 handlebar, 2 middle hinge, 3 quick detach, 4 middle hinge, 5 termination hinges, 6 quick detach, 7 saddles, 8 seatpillars, 9 half bag devices, 91 urceolus, 92 magics are buckled, 93 infantees, 94 mandrels, 95 springs, 96 grooves, 10 seat tubes, 11 termination hinges, 12 trailing wheels, 13 accelerating pulleys, 14 crank and chain-wheels, 15 turning cylinders, 16 folding pedals, 17A pipe, 171 bassoons, 172 tubules, 18B pipe, 19 front-wheels, 20 termination hinges, 21 termination hinges, 22 vehicle frames are preceding manages.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, half-packaging folding bicycle comprises the preceding pipe 22 of vehicle frame, seat tube 10, handlebar 1, folding pedals 16, saddle 7, seatpillar 8, front-wheel 19, trailing wheel 12 etc.; Be provided with X type vehicle frame between pipe 22 and the seat tube 10 and be responsible for before vehicle frame, X type vehicle frame is responsible for by A pipe 17 and B pipe 18 and is constituted; Four ends at A pipe 17 and B pipe 18 respectively are provided with a
