Abstract
The utility model provides a labor-saving rapid chain-tooth disc for a foot-actuated bicycle and a tricycle with a convex supporting point which can not only save labor, but can also increase the speed quickly. The utility model is formed by the convex supporting points arranged on the chain-tooth disc and the chain-tooth disc. The convex supporting points arranged on the lower edge of the crank arm of the big crank supports the crank arm of the big crank tightly to bear and transfer the power generated when the big crank is stepped downwards directly, which achieves the purpose of labor saving and quick speed increasing. The utility model has simple structure.
Description
Affiliated technical field:
The utility model relates to a kind of bicycle that has a protruding Zhi Dingdian, three-wheel vehicle with the fast zipper saw disc device of laborsaving speed.Play the laborsaving effect of pick up speed rapidly again when scrunching.
Technical background:
Known to the public, the design of all at present bicycles, the power of three-wheel vehicle all is to kidnap moving axis greatly by scrunching, and drives zipper saw disc again through axis and rotates, and again power is passed to the back flywheel by zipper saw disc then and drives it and advance.We know, turn greatly with the fixedly part of zipper saw disc is unique twisted strip of transmission of power, and its captive joint part only accounts for about 1/5 of whole chain chain wheel area, in other words, turning when scrunching the power that produces greatly downwards can only pass to greater than its zipper saw disc of several times by this about 1/5 place, could pass to the back to power by zipper saw disc again.Like this, just caused the lost and waste of transmission of power, simultaneously, also the influence of blocking because of " the bottle footpath " of this 1/5 place formation has also caused the increase of the resistance of transmission of power, has brought difficult and effort so give to scrunch.
Summary of the invention:
Solve above-mentioned defective and deficiency for overcoming, the utility model provide a kind of have protruding Zhi Xiangdian directly the bicycle, three-wheel vehicle of transferring power with the fast zipper saw disc of laborsaving speed.
The technical scheme that its technical matters that solves the utility model adopts is:
Being at the nearly root of zipper saw disc teeth does not influence under teeth and the mutually meshing situation of chain, be provided with the Zhi Dingdian of a projection, this Zhi Dingdian is positioned at the lower edge of connecting lever greatly that fixes with zipper saw disc, directly prop up and head on connecting lever greatly, when turning greatly when being stepped downwards, connecting lever is pressed at once and is tightly propped up on the Zhi Dingdian that withstands on following projection, force zipper saw disc to rotate, and directly bear the power that turns greatly, changed the necessary process earlier of the transmission axis of power in the past, drive zipper saw disc by axis again, could pass to power the waste situation repeatedly of back then.The axis of this moment is unique transmission necessary that is power, plays just that installation is fixedly coupled effect with turning mutually greatly.Because power is to drive zipper saw disc by Zhi Dingdian directly to pass to the back, solves and reached not only laborsaving but also the purpose of pick up speed rapidly.
The beneficial effects of the utility model are: the area of thrust surface that strengthened zipper saw disc because of the Zhi Dingdian that is located at projection on the zipper saw disc, make zipper saw disc can directly transmit the power that turns greatly, so under any circumstance scrunch the effect that can both play laborsaving rapid pick up speed, it is simple in structure.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1, be plan view of the present utility model.
Among Fig. 1, zipper saw disc projection Zhi Dingdian (1) zipper saw disc is connecting lever (2) zipper saw disc (3) axis (4) zipper saw disc teeth (5) greatly
The specific embodiment:
In Fig. 1, when connecting lever (2) is stepped downwards greatly, the Zhi Dingdian of projection goes up (1) and drives zipper saw disc (3) rotation below being pressed at once, driving chain by zipper saw disc teeth (5) directly passes to power and drives it on the flywheel of back and advance, and this moment with turn twisted strip that the axis (4) that is connected to a fixed no longer is a transmission of power and unique greatly, just play a support and bonded assembly effect.
Claims (2)
1, a kind of bicycle, three-wheel vehicle that has protruding Zhi Dingdian is to be made of Zhi Dingdian and zipper saw disc protruding on the zipper saw disc with the fast zipper saw disc of laborsaving speed, and it is characterized in that: zipper saw disc is provided with the Zhi Dingdian of projection.
2, a kind of bicycle that has a protruding Zhi Dingdian according to claim 1, three-wheel vehicle are with the fast zipper saw disc of laborsaving speed, and it is characterized in that: the Zhi Dingdian of projection is positioned at connecting lever lower edge greatly on the zipper saw disc, directly head on and turn connecting lever greatly.
