Abstract
The utility model discloses a novel crank which comprises a large end, a small end and a connecting handle which is respectively connected with the large end and the small end fixedly. Grooves are formed in the two lateral sides of the connecting handle. The grooves are symmetrically formed along the center lines of the two lateral sides of the connecting handle. According to the novel crank, the grooves are formed in the two lateral sides of the connecting handle, the overall stress of the novel crank can be dispersed, the strength of the novel crank can be improved, the service life of the novel crank can be prolonged, and meanwhile the aesthetic feeling degree of the novel crank can be further improved due to the fact that the grooves are in curved surface transition.
Description
Technical field:
The utility model relates to the bicycle crank field, the crank high more specifically to a kind of intensity, that outward appearance is novel.
Background technology:
Crank is requisite parts in bicycle structure, and because the one end connects sprocket wheel, the other end connects foot-operated, when driving bicycle running, be again a main stressed member, therefore, how improve the intensity of crank and aesthetics is more and more ridden the person of sailing and manufacturing enterprise payes attention to.Crank of the prior art mostly is the shape dresses such as pipe, square tube, oval tube,, no matter these cranks are at aspect service life or aesthetics aspect, all can not meet the market demand.
The utility model content:
The purpose of this utility model just is to provide a kind of novel crank, with existing crank, compares, and can not only improve the intensity of crank, increases the service life, and can also increase aesthetic feeling.
For achieving the above object, a kind of novel crank of the present utility model, comprise large end, small end and the connection handle that is fixedly connected with respectively with large end, small end, and the two sides of described connection handle form groove.
Preferred as technique scheme, described groove is symmetrical arranged along the two sides line of centers of connection handle.
The beneficial effects of the utility model are: the utility model forms groove in the two sides of its connection handle, can disperse the stress of crank integral body, improves its intensity, extend the service life of crank, simultaneously,, because groove is surface blending, can also increase the aesthetic degree of crank.
Description of drawings:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model
In figure: 1, large end; 2, small end; 3, connection handle; 30, groove.
The specific embodiment:
As shown in Figure 1: a kind of novel crank of the present utility model, it comprises large end 1, small end 2 and the connection handle 3 that is fixedly connected with respectively with large end 1, small end 2, the two sides of described connection handle 3 form groove 30; Described groove 30 is symmetrical arranged along the two sides line of centers of connection handle 3.
The utility model forms groove 30 by the two sides at its connection handle 3, can disperse the stress of crank integral body, improves its intensity, extends its service life, simultaneously,, because groove 30 is surface blending, can also increase the aesthetic degree of crank.
The foregoing is only the preferred embodiment that embodies the utility model principle, therefore do not limit protection domain of the present utility model, every equalization of doing according to the utility model change with modify and all belong to the scope of the claims that the utility model contains within.
