Description

A kind of pedal type labour-saving bicycle

Technical field

The utility model relates to a kind of vehicle, is specifically related to a kind of pedal type labour-saving bicycle.

Background technology

Bicycle and manual tricycle are that China labouring people use maximum vehicle and transportation means, and its price is low, need not be oily, and not electricity consumption, energy-conserving and environment-protective are liked by numerous working people deeply.

But traditional bicycle and three-wheel vehicle also have a lot of weak points, because structure is different with method of designing, when garage is walked, need constantly to trample sole with two leg strengths, and be very much effort as long-time walking like this, it is just very difficult particularly to run into uphill road.Traditional bicycle volume is big, and weight is big, and inconvenience is deposited, constant moving.Traditional manual tricycle mainly is the usefulness of shipping goods, but because the structure design is different, no speed-changing mechanism, effort is big, and it is few to haul goods.

Summary of the invention

The purpose of this utility model provides a kind of rational in infrastructure, easy to use, the structure force method of change standard bicycle and three-wheel vehicle makes full use of lever principle, alleviate trample sole firmly and trample number of times, can strengthen advance a kind of pedal type labour-saving bicycle of strength of promotion wheel.

In order to overcome the deficiencies in the prior art, the technical solution of the utility model is to solve like this: a kind of pedal type labour-saving bicycle, comprise by the headstock front fork and connect chassis, chassis is connected with vehicle seat respectively, back axle, the back axle two ends are connected with left back wheel respectively, right rear wheel, the headstock front fork also is connected with front vehicle wheel and brake handgrip, special character of the present utility model is to have the change speed gear box groove in the middle of the chassis, the change speed gear box groove is connected with a change speed gear box, the change speed gear box right side is connected with right tread plate, the left side is connected with left tread plate, a left side, right tread plate connects the post of turning left respectively, the post of turning right, stability column inserts in the stability column sleeve pipe, the stability column sleeve pipe is separately fixed on the car bottom plate by screw, the post of turning left passes through jointed shaft, lever and bearing fixing axle connect No. 1 gear, the post of turning right is by another jointed shaft, another lever and bearing fixing axle connect No. 2 gears, connect first gear wheel shaft in the change speed gear box, connect first very heavy and second very heavy on first gear wheel shaft respectively, No. 2 big gear wheels, connect No. 3 big gear wheels and No. 4 miniature gearss on second gear wheel shaft respectively, connect miniature gears on the 3rd gear wheel shaft respectively No. 5, No. 6 band tooth small faceplate wheels and No. 7 band tooth large faceplate wheels, connect left back wheel on the back axle successively respectively, No. 8 band tooth large faceplate wheels, No. 9 band tooth small faceplate is taken turns and right rear wheel, the chain sealing is nested into band tooth small faceplate wheel No. 6, No. 8 band tooth large faceplate wheels are gone up or sealing is nested into band tooth small faceplates wheel No. 9, on No. 7 band tooth large faceplate wheels, left side tread plate, right tread plate is connected with spring on the chassis respectively, first very heavy and No. 1 gear mesh, second very heavy and No. 2 gears mesh.

The utility model compared with prior art, rational in infrastructure, easy to use, change the structure force method of standard bicycle and three-wheel vehicle, make full use of lever principle, alleviate and trample exerting oneself of sole, can strengthen promote the wheel strength of advancing, long-time driving is also unconsciously tired, and the number of times of trampling sole has been strengthened the speed of wheel, reaches the speed of a motor vehicle few characteristics of exerting oneself soon.Running into upward slope also can have the enough strength of advancing fully, easily goes up a slope, and tread plate is established at grade, also can conveniently stand when needing and travel, and has strengthened onward impulse widely.As long as the utility model removes a rear wheel, i.e. bicycle, it is little that bicycle reaches volume, and weight is little, deposits well, and good carrying action is flexibly.But railway carriage of captive joint is manual tricycle on chassis, and this manual tricycle is firmly little, and it is many to haul goods, and improves twice at least than existing three-wheel vehicle work efficiency, as long as can be transformed into the vehicle that uses for the disabled person to tread plate length lengthening.
