Abstract
The utility model discloses a pedal lever for a pedal bicycle. The pedal lever is structurally characterized in that the pedal lever (1) is arranged, wherein a pedal lever positioning hole (2) is formed in the front end of the pedal lever (1); an arc concave angle release device (3) is arranged at the lower part of the pedal lever (1); and an arc end point of the arc concave angle release device (3) is low in front part and high in rear part. According to the arc concave angle release device (3), a front included angle as an acute angle between a lever of the pedal lever and a crank of the pedal bicycle is changed into an obtuse angle and is always an obtuse angle; and the pedal lever has the advantage of enabling a main chain plate to smoothly rotate forwards and is suitable for pedal bicycles.
Description
Technical field:
The present invention is specifically related to a kind of bicycle with pedal treadle, belongs to the technical field that bicycle with pedal is made.Being adapted to bicycle with pedal uses.
Background technology:
I am the foldable foot-operated vehicle patent to the patent No. ZL201020046045.X of Patent Office of the People's Republic of China's submission on January 8th, 2010, it steps on the driving of driving, adopted treadle to pass through and the connecting rod connecting crank, the drive imput shaft is rotated, structure is more loaded down with trivial details, some scooters that other are also arranged at present, deficiency is improved for this reason, treadle directly contacts with crank shaft, exert pressure to power in crank, the drive drive sprocket rotates, but because the strong point of treadle is located at the front end of vehicle frame, such treadle setting caused the angle angle of the lever of treadle and crank be all the time acute angle at front obtuse angle rear, the reinforcing of treadle is to make the main chain dish become the result of reversing all the time like this, for example patent 03813732.1 this structure wants to make scooter to move ahead, and must set up one or several sprocket wheel and come the Main chain dish to be inverted for the drive wheel forward, and scooter is moved ahead normally.
Summary of the invention:
Purpose of the present invention is exactly for overcoming above deficiency, and providing a kind of does not need loaded down with trivial details transmission connecting structure, and reasonable in design, simple in structure, flexibility and reliability, and treadle lever and crank angle are the bicycle with pedal treadle at obtuse angle all the time.
Technical scheme of the present invention is achieved in that described a kind of bicycle with pedal treadle,
Formed by treadle 1 and treadle knock hole 2, the bottom that is characterised in that treadle 1 is provided with arc concavity angle release gear 3, the arc end points of arc concavity angle release gear 3 is low early and high after, and arc concavity angle release gear 3 makes the lever of treadle 1 and the leading angle acute angle of crank change into the obtuse angle.Treadle 1 needs two in bicycle with pedal is used, the treadle knock hole 2 that arranges on the treadle 1 is loaded on the supporting and location axle of scooter side arm, two bicycle with pedal treadles lay respectively at the both sides of pedal vehicle frame, the arc concavity angle release gear 3 that treadle 1 bottom arranges acts directly on respectively on the crank shaft, alternately do by two treadles 1 and to pump, afterburning main chain dish on crank shaft drive imput shaft forward forward rotates, the top of this treadle 1 can be installed the tail end of pedal or treadle 1 and can be installed foot-operated, the arc concavity angle release gear 3 that treadle 1 bottom arranges, having changed the lever of treadle 1 and the leading angle angle of crank is the obtuse angle, thus the main chain dish can be smoothly forward forward.
A kind of bicycle with pedal treadle of the present utility model, have reasonable in design, simple in structure, flexibility and reliability, treadle lever and crank angle are the advantage that the obtuse angle can make the smooth and easy forward forward of main chain dish all the time.
Description of drawings:
Accompanying drawing is a kind of bicycle with pedal treadle constructional drawing
Among the figure: 1. bicycle with pedal treadle, 2. treadle knock hole, 3. arc concavity angle release gear.
The specific embodiment
Embodiment:
A kind of bicycle with pedal treadle as shown in drawings, its structure is that a treadle 1 is set, front end at treadle 1 arranges treadle knock hole 2, be provided with arc concavity angle release gear 3 in the bottom of treadle 1, the arc end points of arc concavity angle release gear 3 is low early and high after, and arc concavity angle release gear 3 makes the lever of treadle and the leading angle acute angle of crank change into the obtuse angle.
