Embodiment 1

[0020] refer to Figure 1 to Figure 4 As shown, a new anti-off nut of the present invention, the nut includes a sleeve 1, an empty cavity 2 is provided at one end of the sleeve 1 along the axial direction, and the inner diameter of the installation cavity 2 is larger than the inner diameter of the inner hole of the sleeve 1 ; In the installation cavity 2, a number of positioning shrapnels 3 with M-shaped cross-sections are stacked. The more the quantity of positioning shrapnel 3 is, the greater the strength will be. A positioning structure for fixing the positioning elastic piece 3 is provided on the sleeve 1; the positioning elastic piece 3 is stacked from the inside to the outside; the positioning structure is a positioning hook 10 wrapped around the lower end of the outermost positioning elastic piece 3, the positioning hook 10 An integral structure integrally formed with the sleeve 1. Of course, the positioning hook 10 can be a connected ring structure, or several indepe...

Embodiment 2

[0025] refer to Image 6 As shown, the structure of a new anti-loosening nut of the present invention is basically the same as that of Embodiment 1, the difference is that in this embodiment, the outer wall of the sleeve 1 is provided with several annular positioning grooves 9 along the axial direction. Its function is the same as the positioning thread 8 in Embodiment 1, and the installation method is also the same.

Abstract

The invention discloses a novel locking nut, and belongs to the technical field of nuts. The novel locking nut is characterized by comprising a sleeve base; an installation cavity is formed in one end of the sleeve base in the axial direction, and the inner diameter of the installation cavity is larger than the inner diameter of an inner hole of the sleeve base; a plurality of positioning elastic sheets with M-shaped cross sections are stacked in the installation cavity, and positioning structures for fixing the positioning elastic sheets are arranged on the sleeve base; and positioning holes are formed in the centers of the positioning elastic sheets, the inner diameter of the positioning holes is smaller than the outer diameter of a screw to be fixed, and a plurality of avoiding grooves are evenly distributed in the positioning elastic sheets at the edges of the positioning holes at intervals in the circumferential direction. The novel locking nut is ingenious in structure, convenient to use and good in effect, and is used for connecting objects such as furniture and cabinets.

Description

technical field [0001] The present invention relates to a kind of nut, more specifically, relate to a kind of new type anti-loosening nut. Background technique [0002] Due to the relationship between the thread of the existing nut, one party must use a tool to engage it during the process of butt joint with the screw, so that the force application point is exposed. During the furniture assembly process, the exposed parts not only affect the appearance, but also may bring danger to users, especially children. Contents of the invention [0003] The object of the present invention is to provide a new anti-loosening nut with ingenious structure, convenient use and good effect, aiming at the shortcomings of the above-mentioned prior art. [0004] The technical solution of the present invention is realized in the following way: a new anti-escape nut, the nut includes a sleeve, an empty cavity is provided at one end of the sleeve along the axial direction, and the inner diamete...
