AI Technical Summary

Technical Problem

Existing anti-loosening nuts and bolts cannot simultaneously prevent loosening and protect the bolt.

Method used

The T-shaped anti-loosening bolt structure is adopted. By preventing the loosening of the screw, nut and T-shaped screw, the thread design makes the loosening torque of the nut and the T-shaped screw in opposite directions, thus achieving a locking effect.

Benefits of technology

It effectively prevents bolts from loosening and protects the mechanical strength of the screw.

Abstract

A T-shaped bolt assembly used for preventing looseness is composed of an anti-looseness screw, a nut and a T-shaped screw, one end of the anti-looseness screw is provided with a screw hole opposite to threads of the screw, threads of the screw on the axis of the T-shaped screw are the same as threads of the screw hole of the anti-looseness screw, the nut is screwed on the anti-looseness screw with required torque, and the T-shaped bolt assembly is screwed on the anti-looseness screw. And then the T-shaped screw rod is screwed in the required torque reverse direction, and due to the fact that the thread of the nut is reverse to the thread of the T-shaped screw rod, the loosening torque direction of the nut is reverse to the loosening torque direction of the T-shaped screw rod when vibration force is generated in the using process, so that locking is caused, and an anti-loosening structure is achieved.

Description

[Technical Field]

[0001] This invention relates to the field of nuts and bolts, and more particularly to a nut and bolt designed to prevent loosening. [Background Technology]

[0002] As is widely known, there are several types of nuts and bolts that prevent loosening, but none of them can both prevent loosening and protect the bolt. [Summary of the Invention]

[0003] To overcome the shortcomings of the prior art, the present invention provides a nut that can prevent the nut from loosening and protect the screw.

[0004] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0005] The T-shaped anti-loosening bolt consists of an anti-loosening screw, a nut, and a T-shaped screw. One end of the anti-loosening screw has a threaded hole with the opposite thread to the screw thread. The screw thread on the axis of the T-shaped screw is the same as the threaded hole thread of the anti-loosening screw. Tighten the nut onto the anti-loosening screw with the required torque, and then tighten the T-shaped screw in the opposite direction with the required torque. Because the threads of the nut and the T-shaped screw are opposite, when vibration occurs during use, the direction of the loosening torque of the nut is opposite to the direction of the loosening torque of the T-shaped screw, causing it to lock, thus achieving the anti-loosening structure.

[0006] By employing the technical solution described above, the present invention has the following beneficial effects:

[0007] The T-shaped anti-loosening bolt described in this invention can effectively prevent loosening when used within the range of the mechanical strength properties of the bolt material. [Attached Image Description]

Detailed Implementation Methods

[0010] The diagram shows a structure consisting of an anti-loosening screw 1, a nut 2, and a T-shaped screw 3. One end of the anti-loosening screw 1 has a threaded hole with the opposite thread to the screw thread. The screw thread on the axis of the T-shaped screw 3 is the same as the threaded hole thread of the anti-loosening screw 1. The nut 2 is tightened onto the anti-loosening screw with the required torque, and then the T-shaped screw 3 is tightened in the opposite direction with the required torque. Since the threads of the nut 2 and the T-shaped screw 3 are opposite, when vibration occurs during use, the direction of the loosening torque of the nut 2 is opposite to the direction of the loosening torque of the T-shaped screw 3, causing it to lock, thus achieving the anti-loosening structure.

Claims

1. The T-shaped anti-loosening bolt is characterized by: It consists of an anti-loosening screw, a nut, and a T-shaped screw. One end of the anti-loosening screw has a threaded hole that is opposite to the screw thread. The screw thread on the axis of the T-shaped screw is the same as the threaded hole thread of the anti-loosening screw.
