Description

Technical Field

[0001] The utility model relates to the technical field of riveting nuts equipment, in particular to a compression-resistant riveting nut. Background Technique

[0002] A riveting nut, also known as a blind nut and a self-locking nut, is a nut applied to thin plates or sheet metals. It is circular in shape, with a knurled tooth and a guiding groove at one end. Its principle is that the knurled tooth is pressed into the pre-set hole position of the sheet metal. Generally, the diameter of the pre-set hole is slightly smaller than the knurled tooth of the riveting nut. Through pressure, the knurled tooth of the riveting nut is squeezed into the plate, causing plastic deformation around the pre-set hole. The deformed material is squeezed into the guiding groove, thus producing a locking effect.

[0003] For example, in the utility model patent with the publication number: CN212377080U, a riveting nut is disclosed, which includes a riveting nut body. The riveting nut body is provided with a circular ring-shaped boss, an inverted trapezoid ring-shaped boss, a ring-shaped groove and a flanging structure. An external gear ring is interference-fitted on the riveting nut body. A round hole is opened on the riveting nut body, and a threaded sleeve is threadedly connected in the round hole. The structure of the utility model is simple and will not become loose during long-term use, and it is very convenient during actual use.

[0004] Although the above-mentioned riveting nut has a certain locking function, after the above-mentioned riveting nut undergoes collapse deformation, the stability of locking the accessories is insufficient. At the same time, the stability of the support mechanism of the riveting nut against compression is also insufficient, thus reducing the stability of locking the accessories subsequently. Therefore, there is an urgent need for a compression-resistant riveting nut to solve the above-mentioned existing problems. Content of the Utility Model
