The utility model is further arranged to:The reinforcing rib B includes supporting surface A, supporting surface B and is arranged at supporting surface B is upper and is parallel to each other with the resistance surface of reinforcing rib A conflicts, supporting surface A with supporting surface B.
By using above-mentioned technical proposal, reinforcing rib B include supporting surface A, supporting surface B and be arranged on supporting surface B and With reinforcing rib A contradict resistance surface, in order to improve reinforcing rib B respectively with backup washer, nut body side wall and reinforcing rib A it Between connection structure intensity, by being arranged to reinforcing rib B to include supporting surface A, B and resistance surface, supporting surface A, B improve branch Bonding strength between spacer circle and nut body side wall, and resistance surface is adapted setting with the surface texture of reinforcing rib B, then carries High good fit effect, it is ensured that structural strength, and supporting surface A and supporting surface B is parallel to each other, then improves the equal of stress Even degree, it is ensured that satisfactory texture intensity.
The utility model is further arranged to:The outer wall of the nut body is additionally provided with carburized layer.
By using above-mentioned technical proposal, the outer wall of nut body is additionally provided with carburized layer, passes through the outer wall in nut body The carburized layer being equipped with, then improve the structural strength of nut body.
The utility model is further arranged to:The section of the reinforcing rib A is in rounded shape.
By using above-mentioned technical proposal, the section of reinforcing rib A is in rounded shape, by the way that the section of reinforcing rib A is set circle Arc structure, the reinforcing rib A of convex structure possess the support effect of circular arc, it is ensured that backup washer and nut body side wall it Between be in structural strength.
