This practical utility model relates to a kind of portable gravity bicycle.
Background technology
At present, the bicycle on the market is varied, varied, still, is that the portable bicycle of power is not but seen and occurred with gravity.
Summary of the invention
Be the trip that is convenient for people to, it is a kind of with the portable bicycle of own wt as power that the utility model provides.
The technical scheme that its technical matters that solves the utility model adopts is: in the front portion of vehicle body, vertically be equipped with preceding through bearing; Preceding top is the handlebar of Y-shaped (top seal), and its underpart is inserted in preceding; Before with the junction of handlebar, the flexible bolt of a control handlebar is arranged; Being hinged, other has a control bolt in order to control the folding of preceding handle before bolt is with two sections at the middle part of preceding handle; Preceding bottom is a horizontal positioned, is shaped as the front fork of fork-shaped that two end points place along continuous straight runs of front fork have sulculus; The front wheel spindle of front-wheel is housed through bearing on it, just is contained in these two sulculuses; Front wheel spindle protrudes the part of front fork, is close to through nut and front fork; Through also having of being close to of nut and front fork and front frame that preceding mud retaining tile top is connected, the bottom of preceding mud retaining tile is connected through the fork root of bolt and front fork.The rear portion of vehicle body is a horizontal positioned, be shaped as the back vent of fork-shaped; The two-end-point place of back vent, along continuous straight runs has sulculus; Hind axle is housed in the sulculus, and the part that it protrudes back vent is close to through nut and back vent.Be close to through nut and back vent in addition, also have the after poppet that is connected with rear mud-blocking tile top, the bottom of rear mud-blocking tile is connected through the fork heel of bolt and back vent.On the hind axle between two forks of back vent, through bearing trailing wheel and transmission gear are housed respectively; Be contained in ratchet on the trailing wheel (but end ratchet also circumferential ratchet) and the ratchet coupling that is contained on the transmission gear, vice versa.Driving gear (transmitting ratio of two gears is greater than more than 2) with its engagement is housed in the front upper place of transmission gear; With the driving gear shaft of driving gear one, be contained in the inboard of back vent through bearing, it protrudes the part in back vent outside, and a crank is installed; This crank is hinged through the driving crank of connecting rod and front; Be positioned on the vehicle body with the beam warp bearing of driving crank one, its projection at the vehicle body opposite side also is equipped with a crank, and two cranks are formed a coaxial double crank that differs 180 °; In the place ahead of coaxial double crank, be contained on the axle of vehicle body both sides, be symmetrically installed with the pedal that two, side have guide groove through bearing; The corresponding handle of putting into coaxial double crank in the guide groove of two pedals.Like this, when the people on bicycle during double swerve, the pedal of vehicle body both sides is under the effect of human body gravity, will ceaselessly swing up and down, and then drive coaxial crank and rotate, through the transmission of driving gear, transmission gear, ratchet pawl and ratchet, the trailing wheel of bicycle will rotate, and has realized that the utility model is with the purpose of gravity as power.
In such scheme, if with axle and the bearing of the front end of fixed pedestal, change the outfit into a coaxial double crank, with the handle of two groups of coaxial double crank the same side cranks, put into the guide groove of the pedal of the same side separately, can realize the translation up and down of pedal.
If with the front-wheel in the such scheme, change two-wheel into, three-wheel vehicle.
The beneficial effects of the utility model are: when being convenient for people to go on a journey, also can save people's muscle power.
