Anti-loosening nut

Abstract

The utility model provides an anti-loosening nut, and belongs to the technical field of connecting elements. The problem that after an existing nut is installed, a locating structure between the nut and a gasket is lacked, and consequently the gasket is loosened is solved. The anti-loosening nut comprises a nut body, a radial groove is formed in the outer ring of the bottom of the nut body, a plurality of positioning grooves communicated with the radial groove are formed in the nut body, a gasket is installed on the radial groove, a plurality of protrusions installed in the positioning grooves are arranged on the gasket, and buckling parts are arranged on the groove walls of the positioning grooves. And a plurality of clamping grooves into which the buckling parts are clamped are formed in the bulge. The utility model has the advantages that the gasket is prevented from loosening and shifting, and the using effect is improved.

Description

A type of anti-loosening nut Technical Field

[0001] This utility model belongs to the field of connecting element technology, and relates to a nut, and particularly to an anti-loosening nut. Background Technology

[0002] Existing nuts are usually equipped with a screw for locking. The end face of the nut usually contacts the wall. To prevent wear between the nut and the wall, flat washers are added between the nut and the wall. However, these washers lack a positioning structure with the nut, which can cause the washers to shift, especially in moving environments, resulting in ineffective installation and affecting use. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing an anti-loosening nut.

[0004] The purpose of this utility model can be achieved through the following technical solution: an anti-loosening nut, comprising a nut body, characterized in that a radial groove is formed on the outer ring of the bottom of the nut body, and the nut body has a plurality of positioning grooves communicating with the radial groove, a washer is installed on the radial groove, and the washer has a plurality of protrusions installed into the positioning groove, each of the groove walls of the positioning groove has a fastening part, and the protrusions have a plurality of slots for the fastening part to be engaged.

[0005] In the aforementioned type of anti-loosening nut, the washer is made of silicone.

[0006] In the aforementioned type of anti-loosening nut, the fastening part is a cylindrical protrusion structure.

[0007] Compared with existing technologies, this anti-loosening nut has the advantages of preventing the washer from loosening and shifting, thus improving the performance. Attached Figure Description

[0008] Figure 1 is a three-dimensional view of this anti-loosening nut.

[0009] In the diagram, 1 is the nut body; 2 is the washer; 3 is the protrusion; and 4 is the fastening part. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] As shown in Figure 1, this anti-loosening nut includes a nut body 1. The bottom outer ring of the nut body 1 has a radial groove, and the nut body 1 has multiple positioning grooves that communicate with the radial groove. A washer 2 is installed on the radial groove, and the washer 2 has multiple protrusions 3 that are installed into the positioning groove. Each positioning groove has a fastening part 4 on its groove wall, and the protrusion 3 has multiple slots for the fastening part 4 to be engaged. Through the fastening connection between the multiple fastening parts 4 and the slots, the flat washer is positioned on the nut body 1 to prevent the washer 2 from loosening or shifting.

[0012] Preferably, the gasket 2 is made of silicone; the fastening part 4 has a cylindrical protrusion 3 structure.

[0013] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0014] Although this document frequently uses terms such as nut body 1, washer 2, protrusion 3, and engaging part 4, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
