Because the bicycle is driven by hands and feet simultaneously, the utility model not only can be ridden, but also can achieve body building purpose.

Description

A kind of novel body-building bicycle

The utility model relates to a kind of bicycle, particularly a kind of staff by bike, the common bicycle driven of pin.

Announced a kind of " the common bicycle driven of trick " (number of patent application: 93101958.3) at present, the vehicle frame of this bicycle is with two car pipe butt joint welding, cost height, safety are not enough, the guiding mechanism design of this bicycle is complicated, and spring compensator is not set on the steel rope in the guiding mechanism, the swelling device of steel rope is difficult to the complete tensioner of steel rope; Cause in the use steel rope to skid to turn to malfunctioning, the pin drive spindle of this bicycle is divided into identical two parts, be installed on the outside of two car beams of vehicle frame front end respectively, because pin drive spindle cantilever is longer, cause the distortion of pin drive spindle easily, make that the pin drive spindle is normal rigid friction to occur with vehicle frame, the appearance dress is coated with material and is decreased, destruction car load attractive in appearance; A shock-proof spring of this bicycle is installed on the vehicle seat lower end and is connected with cross bar in the back vent, though can reach the shock-absorbing purpose, the poor stability of shock-absorbing.

The purpose of this utility model has provided a kind of vehicle frame, the pin drive spindle is integrated, has adopted steel rope to mend the novel body-building bicycle of tasting device.This bicycle structure is reasonable, practical, the safety of riding, stable higher.

The purpose of this utility model is achieved in that by vehicle frame, vehicle seat, handgrip mechanism, actuating device, wire line guide, driving device and front and back wheel etc. to be formed, and it is characterized in that: vehicle frame adopt two identical "

" the type flat tube be arranged in parallel, two flat tubes are in that front fork, chain stay, seatpillar, the welding of Shock absorber position are installed is fixing; Steel rope in the wire line guide is fixed two pairs of grooved steel plates respectively on its corresponding position, two springs are installed between every pair of grooved steel plate, and every both ends of the spring is separately fixed on the grooved steel plate; Handgrip in the handgrip mechanism is captiveed joint with the clip plate, two handgrip deflection sheavies are separately fixed at the both sides, front and back of clip plate, on the same circumference of each handgrip deflection sheave inboard, have 20～25 dimples equably, two outsides of clip plate also respectively with pairing handgrip deflection sheave on the circumference of dimple same diameter on have a knock hole, the knock hole of each side and and its cooresponding dimple between place a steel ball, the handgrip deflection sheave is fixed on the axle sleeve with back of the body cap; The pin drive spindle make " " type, its upper end is installed between two girders of vehicle frame front end, adopts the antero posterior axis of a cover bicycle that it is connected and fixed; Have a translot and communicate with two races between two races of front fork deflection sheave, die is installed in the translot; On die, have a circular hole.

The utility model advantage: vehicle frame adopts general bending pipes moulding, improve the steadiness of vehicle frame, reduced cost, spring has been installed on the steel rope, solved steel rope and can begin during the course also to have been improved safety by bike, only needed to adjust handgrip deflection sheave angle by the problem of tensioner, just can make steel rope tensioner again, easy to use; This bicycle has been installed two shock-proof springs, has improved the stability of riding.

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

As shown in Figure 1: vehicle frame 6 adopts two bicycle tubing to bend to

Type is pressed into flat tube then, two flat tubes be arranged in parallel, between two flat tubes front fork 15 is being installed, chain stay 24, seatpillar 5 and the welding of Shock absorber 3 positions are fixing, the middle part angle of vehicle frame 6 is between 60 °～80 °, clothes hanger 2 is equipped with in vehicle frame 6 rear ends, the angle of hand-drive bar 8 and vehicle frame 6 is between 10 °～50 °, pin drive spindle 14 upper ends are connected with the front end hinge of vehicle frame 6, its middle part is connected with an end of connecting rod 13, its lower end installation foot-operated 17 and pin backup plate 18, the upper end of hand-drive bar 8 is connected with handgrip 9 with handgrip deflection sheave 10 by clip plate 31, its middle part is passed between two flat tubes of vehicle frame 6 and is connected with its hinge, its lower end is anterior to be connected with crank 20 hinges with the other end of connecting rod 19, crank 20 is fixed on axis 32 the inners, sprocket wheel 21 is fixed on the outer end of axis 32, and sprocket wheel 21 is in transmission connection by chain and hind axle, and two Shock absorbers 3 are housed between the rear end of vehicle frame 6 and the chain stay 24.The front-wheel steering of this car is to be controlled by handgrip deflection sheave 10, steel rope 7, transition pulley 30, front fork deflection sheave 12 by handgrip.Be separately fixed at the both sides, front and back of clip plate 31 as Fig. 2, two handgrip deflection sheavies 10 shown in Figure 3, on the same circumference of each handgrip deflection sheave 10 inboard, have 24 dimples 27 equably, the diameter phi 4 of dimple 27, two outsides of clip plate 31 also respectively with dimple 27 same circumference of pairing handgrip deflection sheave on have φ 4 knock holees, place a steel ball 26 between each side knock hole and pairing dimple, handgrip leading sheave 10 usefulness back of the body cap 28 is fixed on the axle sleeve 29.As Fig. 1, Fig. 4, steel rope 7 shown in Figure 5 is walked around front fork deflection sheave 12, walking around its two ends, transition pulley 30 intersection back again is individually fixed on two handgrip deflection sheavies, front fork deflection sheave 12 is fixed on the standpipe of front fork 15, when car need turn to, staff swings up and down handlebar 9, handgrip deflection sheave 10 is cw or left-hand revolution thereupon also, guiding steel wire rope 7 drives front fork deflection sheave 12 left-right rotation by transition pulley 30, because steel rope intersected about carrying out once when twining, so when left hand to lower swing the time, the front-wheel left-handed turning, right handgrip when lower swing, the front-wheel right-hand turning.Parallelly on the front fork deflection sheave 12 as shown in Figure 6 have two races, article two, have a translot between the race and communicate, die 33 is installed in translot, have a circular hole on the die 33 with two races, steel rope 7 passes from circular hole, and the steel rope punching press is fixed in the circular hole; Two transition pulleys 30 are installed on the hinge axis of hand-drive bar and vehicle frame 6.
