Embodiment 1

[0034] Example 1, such as figure 1 and 2 The shown self-tightening and thread-free nut of the present invention comprises: an outer nut 1, an intermediate nut 2, a clip 3 and an self-tightening nut 4; the inner side of the outer nut 1 has threads, which are screwed with the outer threads of the intermediate nut 2; The outside of the middle nut 2 has threads, which are screwed together with the inner threads of the outer nut 1. The center of the middle nut 2 has a conical hole; Sliding inside; the outside of the self-tightening nut 4 has a thread, which is screwed with the inner thread of the outer nut 1, and the center of the self-tightening nut 4 has a hole.

Embodiment 2

[0035] Example 2, such as figure 1 and 3 The automatic tightening method of self-tightening wire-free nut of the present invention shown, comprises the following steps:

[0036] 1) The screw is inserted from the middle of clip 3;

[0037] 2) Rotate outer nut 1;

[0038] 3) The middle nut 2 rotates relative to the outer nut 1;

[0039] 4) The middle nut 2 drives the clip 3 close to the self-tightening nut 4;

[0040] 5) The clip 3 tightens the self-tightening nut 4 and drives the self-tightening nut 4 to rotate until the outer nut 1 tightens the connected parts and stops rotating.

Embodiment 3

[0041] Example 3, such as figure 1 and 3 The automatic unscrewing method of the self-tightening and wire-free nut of the present invention shown in the present invention comprises the following steps:

[0042] 1) Rotate outer nut 1;

[0043] 2) The middle nut 2 rotates relative to the outer nut 1;

[0044] 3) The middle nut 2 drives the clip 3 away from the self-tightening nut 4;

[0045] 4) The clip 3 slides relative to the middle nut 2 to loosen the clamped screw.

Abstract

The invention discloses a self-tightening screw-free nut. The self-tightening screw-free nut is composed of an outer nut, a middle nut, a clamping piece and a self-tightening nut. Tightening or loosening can be automatically completed only by rotating the outer nut, screw opening is not needed, cost is saved, and the working efficiency is improved.

Description

technical field [0001] The present invention relates to nuts, and more particularly, to self-tightening, thread-free nuts. Background technique [0002] At present, when the screw is connected to the nut, it is necessary to open the wire on the screw, which consumes a lot of time and cost, and is often unusable due to problems such as thread rust, slipping, and looseness; The solid steps are cumbersome to operate, and the advantages are not obvious. The self-tightening and thread-free nut of the present invention does not need to be threaded on the connected screw, steel bar, pipe and other parts, and can be automatically tightened or loosened as long as the outer nut is rotated, and can be used for fastening parts such as screw rod, steel bar and pipe or butt. Contents of the invention [0003] In order to overcome the deficiencies of the background technology, the self-tightening and thread-free nut of the present invention has the following advantages: no need to open...
