Description

Single wheel vehicle

The utility model relates to a kind of bicycle, the wheelbarrow that especially a kind of body-building is used.

At present, the used stage property wheelbarrow of more existing professional bodies mostly is self manufacture, there are not unified structure and specification, the car seat that has adopts asymmetrical shape, the pattern of sitting according to bicycle fully, such seat difficulty of riding, moving the doing of especially turning and turn-taking is difficult to realize, place bearing on the axletree that has, the weight that promptly increases car strengthens cost again, and the size of axle is the key of decision wheel stability, oversize vehicle body is swung easily, poor stability, size then insufficient strength less than normal, the fork span can't be finished, crank length also is critical component, at present many employings of car crank standard bicycle crank is different in size, and is type linearly, the middle flexibility of riding is bad or the like, these problems all are the key links of this product, but because various ways differ, handle affairs by rule of thumb, and product only limits to peoperty, quantity is minimum, and therefore, some problems never have good terms of settlement.

The purpose of this utility model is to provide a kind of body-building wheelbarrow that is beneficial to balance in view of above-mentioned defective.

The purpose of this utility model is achieved in that

The utility model is formed, is fixed a saddle pillar below the saddle by saddle, crotch, wheel, crank, pedal, saddle pillar is inserted in the upper end of crotch breeches pipe, and fix by clamp and bolt, nut, it is characterized in that: wheel shaft is a stepped shaft, its therefrom mind-set outward successively left and right symmetrically be fixed with floral disc, be with axle bush, and be fixed with crank; Being fixed on the floral disc of width of cloth bar by center-side, the outer end is fixed on the rim, and the axle bush fixed outside has upper and lower bearing cap shim, and wherein two upper ball covers are connected as a single entity with the lower end of crotch two forks respectively, upper and lower bearing cap shim is fixed together by bolt, nut, simultaneously crotch and wheel is connected together.

Saddle is the streamline contour of symmetry, and seat board and saddle pillar below it are fixed together, and is foam plastic cushion in the middle of the saddle, and upper surface has one deck covering.

The fork of crotch is a linear, is convenient to keep balance.

Crank has camber, and fixedly the nut of clamp has wrench.

The utility model is because the seat saddle is a symmetric figure, and institute is convenient to turning and is easy to keep balance so that bicyclist's recoil is even, and can be by adjusting the height of adjusting saddle on the clamp.Fork is designed to linear, can guarantee that car load and gravity center of human body are consistent.Wheel shaft is that stepped appearance is convenient to fixed bushing, floral disc, and crank is designed to the crank with camber, and is attractive in appearance, increased elasticity and dynamics.The utility model step the rotation of toe clip moving axis, thereby drive wheel and crank rotates synchronously because axle and rim, crank are fixed as one.Change before the crank advance the puck, wheel, crank moves backwards, changes behind the wheel, can turn by center of gravity inclination and balance, because double arm swing keeps the balance of left, right, front and rear to ride.

The utility model can be as of primary and secondary students general exercise project, fill up the blank of dynamical equilibrium teaching aid in the teaching, play make the student in amusement and recreation, exercise health, increase the effect of sensitieness and balanced capacity.

Below in conjunction with drawings and Examples the utility model is further described.
