Abstract
The utility model discloses a kind of external groove type ball, belong to auto parts and components field.It comprises ball body, described ball body ectosphere wall there are some grooves offered along ball body length direction, be provided with some balls in described groove, described ball part protrudes groove, and the end symmetric of described slot opening is provided with the retaining member preventing ball from departing from groove.The utility model on the basis of existing technology, by offering groove on ball body ectosphere wall, some balls are set in groove, and prevent ball from departing from the retaining member of groove, the rolling action of ball effectively can reduce the injury that between housing and ball, frequent contact friction brings, and then avoids it on the impact in the working life of housing and ball.
Description
Technical field
The utility model relates to auto parts and components field, particularly relates to a kind of external groove type ball.
Background technique
Ball of the prior art is one of very important parts in auto parts and components field, but Shortcomings on its vibrational power flow, its outer spherical surface in housing with the contact friction frequently of cylindrical slot inner ball surface, greatly reduce the working life of housing and ball, be unfavorable for long-run development, following market demand cannot be satisfied with, have necessity of improvement.
Model utility content
Problem to be solved in the utility model is: provide a kind of external groove type ball, and it has the feature of long service life compared to existing technology.
The utility model technical solution problem adopts following technological scheme:
A kind of external groove type ball, comprise ball body, described ball body ectosphere wall has some grooves offered along ball body length direction, in described groove, is provided with some balls, described ball part protrudes groove, and the end symmetric of described slot opening is provided with the retaining member preventing ball from departing from groove.
The beneficial effects of the utility model are: the utility model on the basis of existing technology, by offering groove on ball body ectosphere wall, some balls are set in groove, and prevent ball from departing from the retaining member of groove, the rolling action of ball effectively can reduce the injury that between housing and ball, frequent contact friction brings, and then avoids it on the impact in the working life of housing and ball.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model cross sectional representation.
Number in the figure: 1 is ball body, 11 is groove, and 12 is ball, and 13 is retaining member.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As depicted in figs. 1 and 2, a kind of external groove type ball, comprise ball body 1, described ball body 1 ectosphere wall there are some grooves 11 offered along ball body 1 length direction, some balls 12 are provided with in described groove 11, described ball 12 part protrudes groove 11, and the end symmetric of described groove 11 opening is provided with the retaining member 13 preventing ball 12 from departing from groove 11.
The utility model proposes a kind of external groove type ball.The utility model is for the deficiencies in the prior art, on the basis of existing technology, groove 11 offered by ball body ectosphere wall, some balls 12 are provided with in groove 11, described ball 12 part protrudes groove 11, the end symmetric of groove 11 opening is provided with the retaining member 13 preventing ball 12 from departing from groove 11, during work, ball body 1 ectosphere wall in housing with when in cylindrical slot, ball wall contacts, the rolling of ball 12 instead of the friction between housing and ball, like this, under the prerequisite not affecting ball effect, improve the working life of housing and ball.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
