Description

Pedal type amusement bicycle

The utility model relates to a kind of bicycle, particularly relates to a kind ofly both can using as ordinary bicycle, again can be by riding the pedal type amusement bicycle of realizing instead of walking.

China is populous, and almost all there is bicycle in each family, and the usage quantity of bicycle ranked first the position in the whole world, can deserve to be called " bikedom ".Because bicycle storing is convenient, price is low, and has body-building function, and therefore for a comparatively long period of time, bicycle will be the main vehicle that people ride instead of walk.Though a bicycle great variety of models never has breakthrough improvement, mostly is fixed chain, chain sprocket drive, structure is cumbersome, and the method for riding is single, lacks alerting ability, mobility and recreational.

The purpose of this utility model provides a kind of good looking appearance, the method for riding is various, recreational strong, can use as ordinary bicycle, can also can make the pedal type amusement bicycle of surfing simultaneously by the foot-operated instead of walking of realizing again.

The purpose of this utility model realizes by following technical scheme, that is:

Pedal type amusement bicycle comprises that vehicle frame, front fork, front-wheel, trailing wheel, handlebar, saddle, axis, forward and backward pedal and pin step on son.Wherein, the wheel face of front-wheel and trailing wheel is a totally enclosed, side at the front-wheel central shaft hole is provided with an eccentric pivot hole, the wheel shaft of front-wheel is identical with the front-wheel wheel shaft of motor bike, can directly insert in the central shaft hole of front-wheel or the eccentric pivot hole and front-wheel is fixed on the front fork with nut, also detachable lower nut is directly transferred to wheel shaft.Axis is fixed on the bottom girder of vehicle frame, captive joint with two bearing seats respectively in the opposite end of front and back pedal, bearing in two bearing seats on two pedals is installed on the axis respectively, and all sets firmly one on each bearing seat and can make two pedal covering of the fans be launched into the spacing fixture block of certain angle.Being coupling on the bottom girder of front pedal one can be with the upright stay bearing plate that directly is fixed into 90 ° of front running board.The saddle arm is installed on the front running board, one end of pedal leg is fixed on the axis, its other end is extended with the fork leg, pedal one end is coupling on the fork leg, be equipped with a spring pin on the fork leg, spring pin can insert in the circular hole of reserving on the pedal pedal is fixed, and also spring pin can be transferred to, and pedal is folding.And make pedal leg and bottom girder horizontal positioned, and fixed by the spring pin that is fixed on the bottom girder.Handlebar, the assembling of pedal, chain, sprocket wheel and chain cover is identical with ordinary bicycle, so no longer narration.The wheel shaft of trailing wheel is installed in the rear end of vehicle frame bottom girder, and back sprocket wheel is identical with ordinary bicycle, is equiped with flywheel whith square teeth respectively at the two ends of rear axle.A sector of one of them flywheel whith square teeth and pedal rear end directly meshes, and another flywheel whith square teeth is meshed with another sector of pedal rear end by guide wheel.Be equiped with bearing in the axis hole of guide wheel, this bearing is installed on the fulcrum that is fixed on the bottom girder.

Be installed with a plurality of spring pins on the bottom girder of pedal below, above-mentioned front and back for front and back pedal buffer limit.

During use,, then the front-wheel wheel shaft is installed in the central shaft hole of front-wheel if normally by bike, again stay bearing plate is connected with bolt with adapter plate on the front running board, make front running board be fixed into 90 °, saddle pole also is erected into 90 ° simultaneously, so just can work as ordinary bicycle and ride.

If work as bicycle with pedal, then stay bearing plate is put down, saddle also puts down with front running board, pedal is folding, when pedaling front running board, the sector anticlockwise motion of pedal rear end, and drive the guide wheel right-hand revolution, guide wheel ingear flywheel whith square teeth is rotated counterclockwise, and then the drive car body travel forward.When pedaling back step, fan type tooth clockwise direction rotates and makes anticlockwise motion for moving guide wheel, then the flywheel whith square teeth that is meshed with guide wheel clockwise rotates, very heavy inoperative, flywheel idle running is with the direct ingear flywheel whith square teeth of sector anticlockwise motion and drive car body and travel forward then.

If make the car body surf boarding, then the front-wheel wheel shaft is inserted in the eccentric pivot hole of front-wheel, and both can with nut is fixing.

The utility model promptly is a kind of vehicle, is again a kind of converter tools, both can advance as bicycle, can also use as ordinary bicycle simultaneously as the surfing campaign again, and be diverse in function.The utlity model has simple in structure, cost is low, aesthetic in appearance, recreational advantage such as strong.
