Abstract

The utility model relates to a telescopic folding type bicycle; the height of a saddle and the length of a crossbeam can be conveniently adjusted; a damper is arranged between the bicycle crossbeam and a front vertical tube; handle bars and pedals can be folded; an intermediate gear is additionally arranged between a wheel disc of a middle axle and a rear flywheel; a first-step transmission is altered to a second-step transmission. The utility model can telescope and extend, which has the advantages of convenient carrying and storage, good damping performance, and comfort and portability in riding.

Description

Telescopic folding bicycle

---the utility model belongs to Bicycle, is a kind of telescopic folding formula bicycle.

At present, common bicycle is made up of car body and wheel, and handlebar, car body relative position are fixed, and volume is bigger, deposits and carry inconvenience, and the resident of story height takes on the car difficult more downstairs.

The purpose of this utility model is: provide that a kind of vehicle frame is scalable, handlebar is collapsible, vehicle seat is convenient to adjust up and down, and the good telescopic folding bicycle of damping performance.

Solution of the present utility model is on the rear profile tube of car body adjusting cotter to be housed; Be fixed with sleeve pipe on the rear profile tube, the car beam is that block form is two-tube, passes sleeve pipe, and is fixed on the preceding standpipe by bearing pin, and set pin is housed on the sleeve pipe, and the car after-frame is fixed on the sleeve pipe, and preceding standpipe is equipped with bumper between Che Liang.Handlebar is fixed on the preceding standpipe by bearing pin, be with sliding sleeve on the preceding standpipe, between sliding sleeve and the preceding standpipe thrust spring be housed, be connected with arc pull bar between sliding sleeve and the handlebar, sliding bone puts the dress pin, and on the preceding standpipe of pin correspondence position lower limit hole and upper limit hole is arranged.

The utility model is scalable, deposits with easy to carry, and damping performance is good, and it is comfortable light to ride.

Below in conjunction with accompanying drawing structure of the present utility model is described in detail:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a handlebar part scheme drawing.

The utility model is made of handlebar 1, wheel 2, on the rear profile tube 3 of car body 1 adjusting cotter 5 is housed; Be fixed with sleeve pipe 6 on the rear profile tube 3, car beam 7 is that block form is two-tube, passes sleeve pipe 6, and is fixed on the preceding standpipe 10 by bearing pin 11, and set pin 8 is housed on the sleeve pipe 6, and car after-frame 9 is fixed on the sleeve pipe 6, between preceding standpipe 10 and the car beam 7 bumper 12 is housed.Handlebar 13 is fixed on the preceding standpipe 10 by bearing pin, be with sliding sleeve 14 on the preceding standpipe 10, between sliding sleeve 14 and the preceding standpipe 10 thrust spring 16 is housed, be connected with arc pull bar 17 between sliding sleeve 14 and the handlebar 13, pin 15 is housed on the sliding sleeve 14, and on the preceding standpipe 10 of pin 15 correspondence positions lower limit hole 18 and upper limit hole 19 is arranged.In the time of need dwindling car body 1, transfer loose adjusting cotter 5, pusher block bar 4 downwards reduces vehicle seat, transfers loose set pin 8, promotes sleeve pipe 6 forward, and rear profile tube 3, rear wheel, after-frame 9 be standpipe 10 nearby reliably.With pin 15 19 dial-outs from the upper limit hole, two ends handlebar 13 closes up, and by arc pull bar 17 sliding sleeve 14 is moved down, pin is entered in the lower limit hole 18, can make handlebar 13 folding, when recovering to launch handlebar 13, according to carrying out with folding opposite approach, the tension force of thrust spring 16 launches handlebar 13.Bumper 12 two ends are connected respectively with in preceding standpipe 10, car beam 7 bearing pins, constitute damping, and damping performance is good.In addition, increase mesomerism gear 21 between axis wheel disc 22 and rear flywheel 20, become the one-level transmission and be the secondary transmission, it is light to ride, and foot-driven lever 23 also can be made the folding treadle by bearing pin and slider mechanism.
