Abstract

The utility model provides a gear footplate bicycle belonging to the bicycle manufacture field, the structure comprises a bicycle centre shaft, a wheel disk and a bicycle frame, the bicycle centre shaft is arranged on the bicycle frame, the wheel disk is arranged on the right side of the bicycle centre shaft, the left and the right sides of the bicycle frame are separately equipped with a gear with ratchet structure, the gears with ratchet structure are separately jogged with the rack bars that are equipped on the bicycle frame, a plurality of sliding holes are correspondingly perforated on the rack bars, and a guide post that is fixed on the bicycle frame is arranged in each sliding hole, the bottoms of the gears are separately equipped with an offsetting spring, the upper portions of the gears are separately equipped with a footplate. Compared with the prior art, the gear footplate bicycle of the utility model has the advantages of rational design, simple structure, low fabrication cost and the like, and the utility model can not only be capable of riding, but also be used as an exercise bicycle.

Description

The gear bicycle with pedal

(1) technical field

The utility model relates to a kind of bicycle, specifically a kind of gear bicycle with pedal.

(2) background technology

The bicycle of prior art is that version or purposes function are all varied, but the bicycle with a car multi-purpose function is not a lot.

(3) summary of the invention

Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of gear bicycle with pedal of reasonable in design, simple in structure, one-object-many-purposes is provided.

The technical scheme that its technical matters that solves the utility model adopts is:

The gear bicycle with pedal, comprise bicycle middle shaft, wheel disc and bicycle rack, bicycle middle shaft is arranged on the bicycle rack, wheel disc then is arranged on the right side of bicycle middle shaft, be arranged with the gear of band ratchet structure in the left and right sides of bicycle rack and wheel disc, the band ratchet structure gear respectively be arranged on bicycle rack on tooth bar be meshed, correspondence has slide opening on the tooth bar, be provided with the guidepost that is fixed on the bicycle rack in the slide opening, the bottom of gear is respectively arranged with retracing spring, and the top of gear is respectively arranged with pedal.

Gear bicycle with pedal of the present utility model, its principle of work is as follows:

Under the combined action of foot pedals and retracing spring, tooth bar is done up and down reciprocatingly along guidepost, because the wheel and rack engagement of band ratchet structure, thereby the interval commutation that changes into gear rotatablely moves, because gear has ratchet structure, so as long as after rationally installing, gear rotates can only give bicycle middle shaft with onward impulse, hinders the empty acting of power.

Gear bicycle with pedal of the present utility model compared with prior art, the beneficial effect that is produced is: reasonable in design, simple in structure, both rideable, can be used as body-building bicycle again and use.
