Abstract
The utility model belongs to the field of common mechanical manufacture. A rotating shaft of a traction bar is arranged on the central part of a universal joint, and the hollow universal joint can make the traction bar swing forward and backward with the rotating shaft as the center. Upper beams of the bicycle of the utility model are double beams; the traction bar is arranged between the two beams; the lower end of the traction bar is provided with fork ends forked on both sides of a lower beam; the lower ends of the forks end are connected with chains; the left and the right fork ends are respectively provided with a flying rafter and a chain; the right fork end is connected with the right chain and is fixed on a chain at the upper end; the left fork head is connected with the left chain and is fixed on a chain at the lower end. When the lower end of the traction bar moves backwards, the left fork head pulls the left chain through a pulley wheel. When the lower end of the traction bar moves forwards, the right fork head pulls the right chain.
Description
The utility model relates to a kind of bicycle, especially can two arms before and after the bicycle of push-and-pull.
Present known bicycle is to be stepped on by people's two legs to drive car, and power is not used at people's upper limbs two arms and other position of human body.
The purpose of this utility model provides a kind of bicycle, and it can not only be stepped on by two legs simultaneously, and two arms can be exerted oneself all over the body in the front and back push-and-pull.
The purpose of this utility model is achieved in that installs front and back wheel respectively on front fork and the vehicle frame, the draw bar middle part is connected on the vehicle frame, connect two chains about the lower end respectively, chain passes through front wheel, the left side is connected by the following chain of front wheel, the right side is connected pulley top chain, every chain joint connects with extension spring, eliminates the gap, installs foot-operated about the draw bar lower end respectively, the upper end connects handgrip and hollow universal-joint, ten thousand joint closures turn to, and the arcuate backrest chair is installed in the stand back, when people's two arms pull back handgrip, the draw bar lower end spurs right side chain drive trailing wheel forward, left side chain is refunded by pulley, and when two arms promoted handgrip forward, the draw bar lower end pulled back, spur left side chain drive trailing wheel again by pulley, this moment, right side chain was refunded again.Because of chair is arranged, human body can not move therefore and backward, and push-and-pull drives before and after such two arms, and all will exert oneself in people's two arms, belly, back, can reach the purpose of fitness and weight losing.
Owing to adopt such scheme, can when travelling by bike, obtain fitness and weight losing, because it is fluted disc, axis accessory are spent in cancellation, simple in structure.
Below in conjunction with accompanying drawing and enforcement the utility model is further specified.
1, handgrip 2, hollow universal-joint 3, draw bar 4, foot-operated 5, pulley 6, extension spring 7, arcuate backrest chair 8, chain 9, vehicle frame 10, pulley bracket 11, front fork 12, front-wheel 13, trailing wheel
Draw bar 3 middle parts are linked on the vehicle frame 9 among the figure, left side chain 8 is connected on the draw bar 3 by pulley 5, chain joint connects with extension spring 6, pulley 5 is installed on the pulley bracket 10, support 10 fixes with vehicle frame 9, and hollow universal-joint 2 is fixed on handgrip 1 lower end, is enclosed within draw bar 3 the first half, chair 7 is fixed on the vehicle frame 9, and front-wheel 12, trailing wheel 13 are installed in respectively on front fork 11 and the vehicle frame 9.
