Circular cone body end of the circular cone you of the screw against copper post.
Further, the quantity of the rectangular notch is set to 3;The quantity of the through hole is set to 3.
Further, the screw rod tail of the screw is set to interior hexagonal structure.
Further, the outer edge of the lower surface of the nut body is provided with matrix step surface.
Further, the perpendicularity between the matrix step surface and the lower surface of nut body is 0.002mm.
The beneficial effects of the utility model are as follows:
(1)This utility model is provided by copper post and screw;The frustum of a cone of the cone and screw of copper post abuts against one Rise, by screw being turned to through hole direction, copper post is squeezed toward the medial surface direction of nut body, reach and lock and anti-loosening Effect.
(2)This utility model is provided by 3 the uniform rectangular notches of ring-type, through hole and screwed holes;It is rational in infrastructure, outward See attractive in appearance.
(3)The screw rod tail of screw is set to interior hexagonal structure by this utility model, it is possible to achieve with die nut by spiral shell Silk is rotated toward nut body medial surface direction, meanwhile, the outer surface in nut body, simple and beautiful structure will not be projected.
(4)The outer edge of lower surface of this utility model by nut body is provided with matrix step surface, is easy to coordinate The use such as bearing of high rotation speed operation is locked, while being provided with matrix step surface, the following table surface damage of nut body is prevented.
Description of the drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is side view of the present utility model.
Specific embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this Content disclosed by description understands other advantages of the present utility model and effect easily.
