Abstract
The utility model discloses a bicycle power-saving device that makes a concerted effort aims at providing a simple structure, easily manufacturing, effectual, the light of riding, the lower and pleasing to the eye bicycle power-saving device that makes a concerted effort of cost. The bicycle comprises a sliding push rod, an arc-shaped track and a crank provided with a small pulley, wherein the sliding push rod constantly pushes the crank to rotate, and a chain wheel and a chain drive the bicycle to travel. The resultant force economizer for bicycle is widely suitable for walking.
Description
Technical field
The utility model relates to a kind of bicycle, and more particularly, it relates to a kind of bicycle that has work-saving device.
Background technology
At present, various bicycles on the market, the actuating device in the bicycle is made up of axis, flywheel, sprocket wheel, chain, crank etc.Though, all can not play effect not only laborsaving but also can pick up speed by speed and foot-operated firmly the size that the size of sprocket wheel is regulated bicycle walking.Up to the present, on market, do not see bicycle not only laborsaving but also can pick up speed as yet.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of simple in structure, be easy to processing and manufacturing, ride comfortable, the labor-saving effect good, do not allow the fatigable bicycle labour saver of making a concerted effort again.
The bicycle of the present utility model labour saver of making a concerted effort comprises that sliding catch bar, arc track and an end is connected with axis, and the other end is equipped with the crank of small sheave, has strengthened the sprocket wheel of cylindrical in addition.Described catch bar one end that slides is contained in down the suitable position of vehicle frame, and can rotate, and the other end is equipped with pedal, and the top is equipped with small sheave and is clipped in the middle of the arc track, plays directed reinforcement effect and underfooting and steps on the prevention effect.
Described arc track is installed on the vehicle frame, must be covered by protecting cover.Described protecting cover must be had in vain and the groove of arc track with radius arc, is convenient to be equipped with the outer pedal of protecting cover and takes action up and down.
The end that described left and right sides crank is equipped with pulley must allow pulley all the time in the bottom of sliding catch bar.
The beneficial effects of the utility model are: 1, firm in structure; 2, simple in structure, be easy to make; 3, the labor-saving effect is good, is applicable to that various places ride, and is in light weight; 4, cost is low.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
In the drawings, bicycle make a concerted effort labour saver mainly by arc track 1, protecting cover 2, pedal 3, small sheave 4, saddle 5, small sheave 6, slide catch bar 7, left and right sides crank 8 etc. and form.
The described catch bar 7 that slides must be installed in down on the vehicle frame by an end, and rotatable, the other end is equipped with small sheave, and small sheave must be clipped in the middle of the arc track.In place pedal is installed near 1.5 centimeters of small sheaves; Described left and right sides crank 8 must be installed in and connect the axis two ends that wheel links, and the other end is equipped with small sheave.Small sheave is all the time in the bottom of catch bar.This is the topmost parts of labour saver.Described arc track 1 must be radius with the length that slides catch bar, and the centre can allow and be contained in the small sheave art skating that slides the catch bar top.The arc track must be made by iron bar thick by 3mm, that 15mm is wide.Must firmly be installed on the front vehicle frame.Described protecting cover 2 must protect laborsaving parts interior, can not with laborsaving parts friction, protecting cover must be had in vain at the position of arc track to allow and be contained in the space that the foot-operated freedom outside the protecting cover is taken action up and down, described pedal 3 must be contained in securely and slide the catch bar upper end, its structure is identical with former bicycle, described small sheave 4 must be installed in the top of sliding catch bar, and can be in the arc track art skating.Described saddle 5 must be able to rotate forward, the end that described small sheave 6 is installed in left and right sides crank with slide catch bar and be connected.
