Abstract
The utility model provides a novel bicycle accelerator which has the structure that pedals of a bicycle are designed as retractable type sliding pedals, a slide block of a sliding connecting bar of every pedal is fixedly connected with a duplex rolling bearing, a cam is clamped by the duplex rolling bearing so as to cause the pedals to regularly slide along the inner wall and the outer wall of the cam through the bearing, thereby the regular prolongation and retraction of the pedals is realized. Furthermore, the inner sides of the large raised head and the small raised head of the cam are respectively connected with an arc inner wall, and a connecting plate which is used to be fixedly connected with a frame of the bicycle is arranged on the cam. The utility model has the advantages of novel structure, simple assembly, obvious effect, quick speed, labor conservation and convenient use, and is a novel bicycle accelerator.
Description
Technical field
The utility model relates to a kind of parts of bicycle, especially a kind of bicycle accelerator.
Background technology
Bicycle is one of main vehicle of using always of people, and is along with the raising of living standards of the people, also more and more higher to the technical requirements of bicycle.In known technology, the patent documentation that relates to bicycle accelerator has some kinds, the accelerator that is installed on the handlebar is arranged, the accelerator that is installed on the wheel of back is arranged, also have by being installed in the tower wheel disc and the different-diameter proportioning conversion that is loaded on flywheel on the rear axle on the axis, improve the accelerator of bicycle speed.But these accelerators all have equipped complicated, and shortcomings such as complex operation bring inconvenience to use.
Summary of the invention
For overcoming the deficiency of prior art, the utility model provides a kind of novel structure, and equipped simple and easy, laborsaving fast, effect is obvious, rides and uses new bicycle accelerator easily.
The technical scheme that its technical matters that solves the utility model adopts is: the pedal leg of bicycle is designed to sliding extension formula pedal leg, on the slide block of the sliding connecting rod of each pedal leg, be fixed with double rolling bearing, duplex bearing clips cam, the pedal leg is slided along cam inside and outside wall set pattern by its bearing, realize the rule elongation and the retraction of pedal leg, big plush copper of cam and small convex head inboard respectively are connected with an arc inner wall, connecting plate is housed on the cam, be fixed on the vehicle frame of bicycle the bicycle accelerator of the set pattern sliding extension formula pedal leg of being formed in order to connect.During use, with sliding extension formula pedal leg of the present utility model load on bicycle middle shaft, load stretcher on the slide link head of pedal leg, cam is fixed on the vehicle frame of bicycle, the big plush copper end of cam makes the pedal leg when pedaling forward towards the bicycle front portion, and its connecting shaft holds along cam and slides to big plush copper end, with the elongation of pedal leg, laborsaving acceleration.
Because technique scheme has been taked in the utility model design, show that it has novel structure through test for several times is on probation again, design innovation, equipped simple and easy, laborsaving fast, advantage such as effect is obvious, and is easy to use is a kind of new bicycle accelerator.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the concrete structure diagrammatic sketch of the utility model embodiment.
Fig. 2 is the left view of Fig. 1 embodiment.
Reference numeral: 1 cam, 2 pedal leg frame linkings, 3 bearings, 4 axis, 5 sliding connecting rods, 6 stretchers.
The specific embodiment
As accompanying drawing 1, embodiment shown in Figure 2, the utility model is the pedal leg with the difference load of bicycle middle shaft 4 both sides, be designed to connect the sliding extension formula pedal leg that sliding connecting rod 5 is formed by frame linking 2, the sliding connecting rod 5 of pedal leg connects connecting rod by sliding shoe and is formed, on the sliding shoe of sliding connecting rod 5, be fixed with double rolling bearing 3, double rolling bearing 3 clips cam 1 (totally 2 on cam), drive the pedal leg and carry out clocklike flexible and contraction along the slip of cam 1 inside and outside wall set pattern, cam 1 even is fixed on the vehicle frame of bicycle the bicycle accelerator of the set pattern sliding extension pedal leg of being formed by the load connecting plate.
Be equiped with the slide groove that makes on double rolling bearing 3 running-fit frame linkings 2 inwalls on sliding shoe two lateral bodys of the sliding connecting rod 5 of the telescopic pedal leg of the utility model respectively.
Two cams 1 of the present utility model, its big plush copper, small convex head inboard, respectively be connected with an arc inner wall, helping inboard bearing slides, the noise of reducing friction, also can respectively design a metallic channel, duplex bearing 3, cam 1 are wrapped in the inside, not wear and tear and stain trouser legs in order that ride the time spent in two cams, 1 periphery.
