Abstract
The utility model belongs to the field of bicycle fittings, and particularly relates to liftable pedals for a bicycle. Each liftable pedal is characterized in that a middle shaft of a common pedal is fixedly connected with a sliding transverse shaft; one end of a threaded shaft is fixedly connected onto a housing; the other end is screwed into a small hole in a crank; one end of a spring is connected with the top end of the housing; the other end is connected with the sliding transverse shaft; racks are arrayed on one side of the housing in parallel at intervals; a thin groove is formed in the other side of the housing; a sliding strip block is placed in the thin groove; the two ends of a small spring are connected with the sliding strip block and the sliding transverse shaft respectively. The pedal generates opposite radial motion along with the sliding transverse shaft and the crank to enable effective length of the crank to elongate or shorten; when work power is certain, and the effective length of the crank is elongated, a labor-saving effect is achieved; when the effective length of the crank is shortened, and pedaling strength is not changed, rotation speed of a chain wheel is increased, and the bicycle accelerates; people with different height and figures can adjust the effective length of the crank to a most suitable state.
Description
Technical field
The utility model belongs to bicycle accessories field, particularly a kind of bicycle Liftable foot pedal.
Background technology
Bicycle is very popular since invention, and has become one of major way of people's trip.In the last few years, along with improving constantly that people require trip instrument, the pleasant variable speed bicycle easily of riding was more and more subject to everybody welcome.The most general variable speed bicycle is all at the in-built gear that is equipped with a set of different size of bicycle rear hub at present, when bicycle is advanced, chain can be placed on different gears by gearshift, thereby change the speed of a motor vehicle, to adapt to different road conditions and cyclist's muscle power.But in real life, because a variety of causes still has a large amount of non-variable speed bicycles to exist, compare variable speed bicycle, in function, have very large defect.Pedal is parts indispensable on all bicycles including variable speed bicycle, is arranged on crank, can only rotate around sprocket wheel axis together with crank, and crank radial motion relatively, the length of crank is also fixed.Under identical acting condition, the moment acting on sprocket wheel is fixed like this.Do not change at bicycle under the condition of effect sprocket radius, just cannot reach the effect of speed change.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and one crank radial motion is relatively provided, the bicycle Liftable foot pedal of the size of Torque-adjusting and then change bicycle running speed.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of bicycle Liftable foot pedal, comprise common pedal, slip transverse axis, tooth bar, spring, threaded shaft, housing, it is characterized in that: the axis of common pedal is fixedly connected with slip transverse axis, threaded shaft one end is fixedly connected on housing, fixes and make housing parallel with crank in the aperture of other end precession crank, and spring one end is connected with housing top, the other end is connected with slip transverse axis, and the tooth bar of right quantity with a gap and be listed in a side of housing.
And described spring one end is connected to housing top corner location, spring is inclined in housing.
And described housing opposite side has thin groove, thin groove is placed with slip stick, separately has the two ends of a little spring to be connected with slip stick, slip transverse axis respectively.
Advantage of the present utility model with good effect is: 1. this bicycle lifting pedal can be by pedal the relative radial motion with crank, the action length of covert change crank, reaches the effect of the laborsaving and speed change of variable speed bicycle; 2. this bicycle lifting pedal can in a disguised form regulate the action length of crank, and the people of different height builds need to be transferred to crank action length most suitable state according to riding, and alerting ability is good, strong adaptability.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front elevation of the present utility model.
Fig. 3 is left view of the present utility model.
Brief description of the drawings mark:
The common pedal of 1-, 2-slip transverse axis, 3-tooth bar, 4-spring, 5-little spring, 6-slip stick, 7-threaded shaft, the thin groove of 8-, 9-sprocket wheel, 10-crank.
Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, the utility model is described in further detail.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of bicycle Liftable foot pedal, comprises common pedal 1, slip transverse axis 2, tooth bar 3, spring 4, threaded shaft 7, housing.The axis of common pedal is fixedly connected with slip transverse axis, threaded shaft one end is fixedly connected on housing, in the aperture of other end precession crank, fix and make housing parallel with crank, spring one end is connected with housing top, the other end is connected with slip transverse axis, and the tooth bar of right quantity with a gap and be listed in a side of housing.Spring tilts with radially at an angle.Housing opposite side has thin groove 8, slip stick 6 can be free to slide at thin groove,, separately there are the two ends of a little spring 5 to be connected with slip transverse axis with slip stick 6 respectively, little spring, along with the motion of slip stick and always in compressive state, produces thrust all the time to slip transverse axis.
The principle of work of this bicycle lifting pedal is: slip transverse axis can be along housing radial motion under spring and external force combined action, and constrains in the gap between arbitrary neighborhood tooth bar by the pulling force of spring 4 and the elastic force of little spring 5.Meanwhile, described pedal also produces relative radial motion along with the motion of slip transverse axis with crank, makes the effective length of crank elongated or shorten, and can be fixed on position suitable between tooth bar along with slip transverse axis.So in working power one timing, when crank effective length increases, can reach labour-saving effect, when crank effective length reduces and pedal force when constant, chain wheel speed increases, and bicycle can produce acceleration.
In the process of riding, also can regulate the position of common pedal 1, concrete operations are: in the time that crank turns to lower position, pushing away common pedal 1 with pin moves toward the direction of compression little spring, until tooth bar can not hinder slip transverse axis radial motion, then when sliding on X direction or moving downward correct position, with pin, slip transverse axis is sent into again to the gap of suitable adjacent rack, pedal also with on move or move down.Because spring 4 tilts, the elastic force of the conicity force of its pulling force and little spring 5 is limited in slip transverse axis in tooth bar gap jointly, and common pedal position is fixed again.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: not departing from the spirit and scope of the utility model and claims, various replacements, it is all possible changing and revising, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
