AI Technical Summary

Technical Problem

Existing automotive tapered nuts are prone to deformation due to excessive clamping force during use, and there is also the problem of loosening and falling off.

Method used

A tapered nut for automobiles has been designed, comprising a nut body, a reinforcing threaded tube, a reinforcing block, a protective component, and an anti-loosening component. Through the cooperation of a protective plate, a positioning block, an insert block, and a T-shaped screw, the nut is stably clamped and prevented from loosening. The anti-loosening function is achieved by utilizing a worm gear structure.

Benefits of technology

This improves the effectiveness of the nuts, prevents deformation and loosening, extends their service life, and facilitates the disassembly and replacement of the protective plate.

Abstract

The utility model relates to the technical field of nuts, and discloses a conical surface nut for an automobile, which comprises a nut body and a reinforcing threaded pipe fixedly mounted at the bottom of the nut body, a reinforcing block is fixedly sleeved above the outer side of the reinforcing threaded pipe, and the top of the reinforcing block is fixedly mounted at the bottom of the nut body. Through mutual cooperation of a protection plate, a positioning block, an inserting block and a T-shaped screw rod, a worker can clamp the nut conveniently through arrangement of the protection plate, so that the nut body is rotated, through arrangement of the T-shaped screw rod, the protection plate which is damaged after long-term use can be disassembled and replaced, damage to the nut body is avoided, and the use effect of the nut body is improved; through mutual cooperation of the moving plate, the threaded rod, the threaded sleeve, the worm gear, the worm and the rotary knob, the moving plate can be driven to move relatively, so that the limiting toothed rod moves relatively to be clamped with the screw rod, the anti-falling effect is improved when the nut is used, and the effect is better.
