Abstract

The utility model discloses a mini bicycle drawn by hand, belonging to the field of bicycles, which comprises a loading base plate; a front steering wheel mechanism is assembled on the front part of the loading base plate, and two back wheels are assembled on the shaft of the back lower part of the loading base plate; each of the back wheels movably connects an overrun coupler which can drive unilaterally, and at least two belt wheels, onto the same shaft; each driven wheel of the overrun coupler is fixedly connected with the adjacent back wheel, and each driving wheel of the overrun coupler is fixedly connected with the two adjacent belt wheels; the insides of the wheel slots of the two belt wheels are respectively connected with one end of the traction rope and one end of the elastic rope. Thus, people standing or sitting on the bicycle can drive the bicycle body by drawing the traction wire winding in the corresponding wheel slot by hand so that people are pulled forward by the bicycle. In addition, upper limbs can be exercised effectively, and the size of the whole bicycle body can be very small and light, which facilitates carrying and using.

Description

But miniature hand-pulled bicycle

Affiliated technical field

The utility model relates to a kind of bicycle, but especially proposes the miniature hand-pulled bicycle that a kind of pulling force that relies on hand drives.

Background technology

How present bicycle drives by pedal, and upper limb body is difficult to obtain effective activity, and whole locomotive body mechanism more greatly, very heavy, be difficult to carry.

Summary of the invention

For overcoming above deficiency, but the utility model proposes a kind of miniature hand-pulled bicycle, it can make the station or thereby the pulling force of people by hand sat onboard drives car body by the car traction, move ahead with car, it can movable effectively upper limb body, and whole locomotive body mechanism can be very little, very light, is convenient to carry everywhere with oneself, use.

The technical solution of the utility model is: but a kind of miniature hand-pulled bicycle, it includes the load substrate, there is steering front wheel mechanism to be assemblied in the front portion of load substrate, have two trailing wheels be assemblied in the load substrate rear lower the axle on, the overriding clutch of described each trailing wheel and a unidirectional transmission of energy and at least two belt pulleys are movably connected on the same axle, the follower of each overriding clutch is fixedly linked with the trailing wheel of vicinity, the driving wheel of each overriding clutch is fixedly linked with two belt pulleys of vicinity, is equipped with at least two hauling ropes and at least two elastic threads in addition.

One end of hauling rope and the elastic threads of ining succession respectively in the race of described two belt pulleys, hauling rope with suitable around in the race that is wrapped in respective pulley, hauling rope is through the pulley of the eyelet hole that is arranged in load substrate front portion, link to each other with the handle of load substrate top, the other end of elastic threads is fixed on the appropriate location on the load substrate, the position of elastic threads is corresponding with the notch direction of company race, and elastic threads is in extended state, two hauling ropes around to identical and consistent with the transmission direction of two overriding clutchs.

Two trailing wheels, two overriding clutchs and four belt pulleys can be movably connected on the same axle by bearing.

Overriding clutch can be a ratchet type overrunning clutch.

Overriding clutch also can be the roller type overriding clutch.

The steering front wheel structure can adopt existing multiple bogie wheel configuration.

Compare with existing foot pedal type bicycle, but the miniature hand-pulled bicycle that the utility model proposes, can make station or seat people onboard, by moving hauling rope with drive pulley with pulling, the driving wheel that drives coupled overriding clutch rotates, meeting drives the follower of corresponding overriding clutch and the trailing wheel that is attached thereto rotates simultaneously, elastic threads is twined in the race of respective pulley automatically, when described trailing wheel lands, can also drive the people's motion on whole locomotive body and the car, can movable effectively upper limb body, can drag the people to advance again; When hand is no longer exerted oneself, be subjected to the counteraction of elastic threads elastic force, the driving wheel of coupled overriding clutch can turn round automatically, reset, and waits for being driven next time; Its car body mechanism can be very little, very light, is convenient to carry everywhere with oneself, use.

The specific embodiment

In one embodiment of the utility model shown in each figure, but miniature hand-pulled bicycle includes load substrate 1, steering front wheel mechanism is assembled by the prior art scheme by front-wheel 2, front wheel spindle 3, U-shaped wheel fork 4 and tuning bar 5, no longer carefully state, the hole 28 of load substrate front portion is passed in 5 activities of tuning bar, and its lower end is fixed on the U-shaped wheel and sticks, and its upper end is c-shaped to the side direction bifurcated, be beneficial to tiptoe and insert, make things convenient for tuning; 6,7 and two mono-directional overrun clutchs of two trailing wheels and four belt pulleys are movably connected on the same axle 8, and axle 8 is fixed on the rear lower of load substrate, and overriding clutch is a prior art, the detailed structure view such as its pusher dog or roller of drawing in this province; The follower 17 of overriding clutch is connected as a single entity with contiguous trailing wheel 6, and trailing wheel 6 is movably connected on the axle 8 by bearing 25; The driving wheel 9 of overriding clutch is linked as an integral body with contiguous two belt pulleys 10,11, and described integral body is movably connected on the axle 8 by bearing 26,27, and bearing is a prior art, and its scheme drawing only draws; One end of hauling rope 12 and the elastic threads 13 of ining succession respectively in the race of belt pulley 10,11, and hauling rope 12 is wrapped in the race of belt pulley 10, hauling rope 12 pass the pulley 15 of the eyelet hole 14 that is arranged in load substrate the place ahead race, link to each other with the handle 16 of load substrate top, the other end of elasticity 13 is fixed on the appropriate location on the load substrate, the position of elastic threads is corresponding with the notch direction of company race, and elastic threads is in extended state; The follower 18 and the trailing wheel 7 of another overriding clutch are connected as a single entity, and the driving wheel 19 of overriding clutch and two belt pulleys 20,21 are connected as a single entity; One end of hauling rope 22 and the elastic threads 23 of ining succession respectively in the race of belt pulley 20,21, and hauling rope 22 is wrapped in the race of belt pulley 20, hauling rope 22 pass the pulley of the eyelet hole that is arranged in load substrate the place ahead race, link to each other with the handle 24 of load substrate top, the other end of elastic threads 23 is fixed on the appropriate location on the load substrate, the position of elastic threads is corresponding with the notch direction of company race, and elastic threads 23 is in extended state; Two

hauling ropes

12,22 around to identical and consistent with the transmission direction of two overriding clutchs;

During use, if with pulling handle 16, hauling rope 12 rotates with regard to the driving wheel 9 of energy drive pulley 10 and then drive overriding clutch, this can make elastic threads 13 twine automatically in corresponding belt pulley 11, also can drive simultaneously the follower 17 of overriding clutch and the trailing wheel 6 that is attached thereto and rotate simultaneously, the trailing wheel 6 that lands can drive the people's motion on car load and the car; When hand not firmly the time, be subjected to the rebound effect of elastic threads 13, the driving wheel 9 of belt pulley 11 and coupled overriding clutch can turn round automatically, reset, and waits for being driven next time; When pulling another handle 24, meeting drives the follower 18 of overriding clutch and trailing wheel 7 rotates simultaneously and be with car to move, when not drawing this handle, as a same reason, the driving wheel 19 of coupled overriding clutch can turn round automatically, reset, and waits for being driven next time; Handle so repeatedly, car just can move continuously; When desiring to turn to, need just can handle wheel flutter 2 and turn to, thereby lead car load to turn to kicking tuning bar 5.
