Embodiment 1

[0510] Such as figure 1 As shown, this embodiment is mainly composed of a "end bolt 1, nut 2, single- and two-way anti-rotation belt sleeve nut tail 5 and its nut tail 4, single- and two-way anti-rotation bolt tail 7, two-tail anti-rotation accessories 8, The anti-off mechanism 9" and other components are composed together, of which:

[0511] 1. The nut tail 4 of the one-way and two-way anti-rotation belt sleeve nut tail 5: what this embodiment adopts is the one-way two-way anti-rotation belt sleeve nut tail 5, and does not adopt the one-way two-way anti-rotation belt end nut 6. Its nut tail 4 belongs to the aforementioned example 18: "axial concentric non-rotating sleeve" bidirectional anti-rotation nut tail 4, specifically, it belongs to a hexagonal sleeve, the outer edge is hexagonal, the inner hole is also hexagonal, and the axial The length is about 120 mm, the wall thickness of the sleeve is about 2 mm, and the diagonal length of the inner hole is 30 mm.

Embodiment 2

[0528] Such as figure 2 As shown, the present embodiment is mainly composed of a "final bolt 1, nut 2, single- and double-direction anti-rotation band tail nut 6 and its nut tail 4, single- and two-way anti-rotation bolt tail 7, two-tail anti-rotation accessories 8, anti-off Mechanism 9" and other components together constitute, of which:

[0529] 1. The nut tail 4 of the one-way and two-way anti-rotation band end nut 6: what this embodiment adopts is the single-two-way anti-rotation band end nut 6 instead of the single-two-way anti-rotation band sleeve nut tail 5. Its nut tail 4 belongs to the "axial concentric non-rotating body 'tube'-shaped two-way anti-rotation nut tail 4, specifically, it belongs to a cylinder, the outer edge is a standard circle, but the inner hole is an internal gear, and the shaft The longitudinal length is about 120 mm, the sleeve wall thickness is about 6 mm, and the diameter of the dedendum circle of the internal gear is 30 mm.

[0530] ...

Embodiment 3

[0542] Such as image 3 As shown, the present embodiment is mainly composed of a "final bolt 1, nut 2, "single and bidirectional anti-rotation band sleeve nut tail 5 or single and bidirectional anti-rotation band tail nut 6" and its nut tail 4, single and bidirectional anti-rotation bolt The tail 7, the two-tail joint anti-rotation fitting 8, and the anti-off mechanism 9" are jointly composed of components, among which:

[0543] 1. Nut tail 4 of "single and bidirectional anti-rotation belt sleeve nut tail 5 or single and bidirectional anti-rotation belt tail nut 6": It should be noted that this embodiment includes both single and bidirectional anti-rotation belt sleeve nut tail 5 and single Two-way anti-rotation belt end nut 6 is available for selection. No matter which one, its nut tail 4 is all identical.

[0544] Its nut tail 4 is basically the same as the nut tail 4 of Embodiment 2, the difference is that "the internal gear is changed into a left-turning inner ra...

Abstract

The invention provides a bolt connecting pair with a function of preventing a nut from rotating towards the loosening direction. According to the technical scheme, the bolt connecting pair at least comprises a bolt connecting pair body, wherein the bolt connecting pair body at least comprises a tail section bolt (1), a nut (2), a one-way or two-way rotation-stopping nut tail (5) with a sleeve, a one-way or two-way rotation-stopping bolt tail (7), a two-tail common rotation-stopping accessor (8) and a locking mechanism (9); and the nut (2) is matched with the tail section bolt (1). Alternatively, the bolt connecting pair at least comprises a bolt connecting pair body which at least comprises a tail section bolt (1), a one-way or two-way rotation-stopping nut (6) with a tail, a one-way or two-way rotation-stopping bolt tail (7), a two-tail common rotation-stopping accessor (8) and a locking mechanism (9). From the above, the bolt connecting pair has the advantages that the nut is prevented from rotating towards the loosening direction, so that the nut cannot be screwed off from the bolt.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a bolt connection pair with anti-loosening function. Background technique [0002] There are various kinds of anti-loosening devices for the existing bolted joints, and no bolted joints have been found that can achieve anti-loosening "by preventing the nut from turning in the direction of loosening and retreating". Contents of the invention [0003] The object of the present invention is to provide a bolt connection pair with the function of "preventing the nut from rotating in the direction of loosening and retreating". In order to achieve the above object, the present invention adopts the following technical solutions: [0004] One, general description of the present invention [0005] (1) "Regulations on Simplified Explanation" of the Claims and Description [0006] 1. The first simplified elaboration regulation [0007] Generally speaking, "bolt connection becoming loose" is ...
