AI Technical Summary

Technical Problem

The existing hexagonal cylindrical screws wear out after multiple twists, resulting in the hexagonal wrench not being able to rotate accurately, loose during the twisting process, and in severe cases the bolt cannot be unscrewed, affecting the working progress.

Method used

A wear-resistant hexagonal cylindrical screw including a cylindrical head, an auxiliary structure and a push structure is designed. The auxiliary structure provides a convenient tool interface to facilitate screwing and removing screws through the combination of moving parts, cylindrical rods, cross grooves and prisms; the push structure simplifies the removal process of the auxiliary structure through the cooperation of sliding plates, telescopic rods, springs and push rods.

Benefits of technology

It effectively avoids the inconvenience of screw wear, solves the loosening problem caused by the degradation of wear-resistant layer performance, simplifies the screw screw rotation and removal process, improves working efficiency, and extends the service life of the screw.

Abstract

The utility model discloses an anti-abrasion hexagon socket cap screw, and relates to the technical field of screws. The anti-abrasion hexagon socket cap screw comprises a cylindrical head, an auxiliary structure and a pushing structure, the bottom of the cylindrical head is fixedly connected with a screw, the auxiliary structure comprises a movable part, a cylindrical rod, a cross groove and a prism, the movable part is arranged in the cylindrical head, the cylindrical rod is fixedly connected to the bottom of the movable part, and the cylindrical rod is slidably connected to the inner wall of the cylindrical head; the cylindrical rod is slidably connected with the inner wall of the screw, the prism is fixedly connected to the bottom of the cylindrical rod, the cross groove is formed in the surface of the prism, the through hole penetrates through the cylindrical rod and the prism, the screw can be conveniently taken out through various tools through the auxiliary structure, and the situation that the screw is not convenient to unscrew due to abrasion is avoided; the problems that a traditional screw is loosened in the screwing process due to performance reduction of a wear-resisting layer, and the work progress is affected due to the fact that a bolt cannot be screwed off seriously are solved.
