Abstract
The utility model relates to a butterfly-shaped lock washer. The butterfly-shaped lock washer comprises a circular-ring-shaped body with the conic cross section. An anti-sliding groove is formed in the inner ring of the outer wall face of the body, the peripheral wall of the body is provided with an outer groove, and the outer groove is formed around the outer peripheral wall of the body in an annular mode. The butterfly-shaped lock washer has a better anti-sliding effect.
Description
Technical field
The utility model relates to a kind of butterfly lock washer.
Background technique
The butterfly lock washer generally includes the circular body that the cross section is truncated cone shape, and the inner ring of the upper wall surface of described body is provided with anti-slip tank, yet traditional butterfly lock washer, bolt is tightened when installing, and active force is big inadequately between butterfly lock washer and the bolt, thereby anti-loosing effect is brought influence.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of butterfly lock washer that improves anti-loosing effect.
For achieving the above object, the utility model provides following technological scheme: a kind of butterfly lock washer, comprise that the cross section is the circular body of truncated cone shape, the inner ring of the upper wall surface of described body is provided with anti-slip tank, the periphery wall of described body is provided with outer groove, and described outer groove is centered around on the periphery wall of body in the form of a ring.
By adopting technique scheme, the two side of outer groove forms certain metallic elastic power, and bolt is carried out tensioner, thereby has improved anti-loosing effect.
The utility model further arranges: the inner circle wall of described body is provided with inner groovy, and described inner groovy is centered around on the inner circle wall of body in the form of a ring.
By adopting technique scheme, the two side of inner groovy forms certain metallic elastic power, and bolt is carried out tensioner, thereby has further improved anti-loosing effect.
The utility model further arranges: the degree of depth of described outer groove and inner groovy equals the thickness of described body.
By adopting technique scheme, make that processing is convenient.
The utility model further arranges: the outer ring of the lower wall surface of described body evenly is provided with slideproof tooth.
By adopting technique scheme, slideproof tooth is tightened with adorning object, has further improved anti-loosing effect.
Below in conjunction with accompanying drawing the utility model is further described.
