Abstract
The invention provides a kind of ratchet, it comprises: circular body; Be periphery in described body edges and the ratchet of regular array; Circular shaft, itself and described body are positioned at same axle center and are arranged at described body side, described circular shaft inside is provided with a passage, described channel setting is in the axle center of described circular shaft and continuous through described body and circular shaft, described body is also provided with some through holes, described through hole is symmetrical arranged centered by circular shaft, and between described ratchet and circular shaft.By such structure, reduce the weight of ratchet, and reduce the manufacture cost of ratchet.
Description
Technical field
The present invention relates to mechanical field, particularly relate to a kind of ratchet.
Background technique
As everyone knows, ratchet is a kind of unidirectional drive parts.Its by lock pawl and ratchet mutually against, to realize unidirectional drive or stop.It is comparatively large that ratchet of the prior art also exists weight, the shortcoming that cost is higher.
In view of this, be necessary to be improved ratchet of the prior art, to solve the problem.
Summary of the invention
The object of the present invention is to provide a kind of ratchet, in order to reduce the weight of ratchet, reduce the manufacture cost of ratchet.
For achieving the above object, the invention provides a kind of ratchet, it comprises: circular body; Be periphery in described body edges and the ratchet of regular array; Circular shaft, itself and described body are positioned at same axle center and are arranged at described body side, described circular shaft inside is provided with a passage, described channel setting is in the axle center of described circular shaft and continuous through described body and circular shaft, described body is also provided with some through holes, described through hole is symmetrical arranged centered by circular shaft, and between described ratchet and circular shaft.
As a further improvement on the present invention, the internal face of described circular shaft is provided with a keyway.
As a further improvement on the present invention, described body is provided with four through holes.
As a further improvement on the present invention, described through hole is & field shape.
As a further improvement on the present invention, described circular shaft is also provided with an installation guide portion.
As a further improvement on the present invention, the outside of described circular shaft is also provided with a ring annular groove.
As a further improvement on the present invention, the width of described ratchet is greater than the width of described body.
Compared with prior art, the invention has the beneficial effects as follows: by such structure, reduce the weight of ratchet, and reduce the manufacture cost of ratchet.
Accompanying drawing explanation
Fig. 1 is the front view in a kind of ratchet one of the present invention embodiment;
Fig. 2 is the sectional view along A-A line in Fig. 1.
Embodiment
Below in conjunction with each mode of execution shown in the drawings, the present invention is described in detail; but should be noted that; these mode of executions are not limitation of the present invention; those of ordinary skill in the art are according to these mode of execution institute work energy, method or structural equivalent transformations or substitute, and all belong within protection scope of the present invention.
Shown in please refer to the drawing 1, Fig. 1 is the front view in a kind of ratchet one of the present invention embodiment.In the present embodiment, a kind of ratchet 10, it comprises: circular body 1; Be periphery in described body 1 edge and the ratchet 2 of regular array; Circular shaft 3, itself and described body 1 are positioned at same axle center and are arranged at described body 1 side.
Shown in composition graphs 2, in the present embodiment, this circular shaft 3 inside is provided with a passage 31, and described passage 31 is arranged at the axle center of described circular shaft 3 and continuous through described body 1 and circular shaft 3.In the present embodiment, this body 1 is also provided with four through holes 11, and these four through holes 11 are symmetrical arranged centered by circular shaft 3, and between described ratchet 2 and circular shaft 3.
Concrete, the internal face 32 of this circular shaft 3 is provided with a keyway 33.Like this, drive main spindle (not shown) by key and this keyway 33 phase clamping, to realize the reliable fixing of drive main spindle and ratchet of the present invention 10.
Further, this through hole 11 is & field shape, effectively can reduce the infringement that stress that ratchet 10 produces in loading process causes this ratchet 10 like this, significantly reduce the weight of this ratchet 10 simultaneously, and do not reduce its integrally-built fastness.
In the present embodiment, this circular shaft 3 is also provided with an installation guide portion 35, and drive main spindle and circular shaft 3 can be facilitated so more easily to assemble.
More specifically, the outside of this circular shaft 3 is also provided with a ring annular groove 34.Meanwhile, the width of this ratchet 2 is greater than the width of described body 1.
A series of detailed description listed is above only illustrating for feasibility mode of execution of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
