[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4As shown, in this embodiment, an anti-slip rivet nut includes a rivet nut body 3 and a plate 5. The rivet nut body 3 is slidably inserted in a mounting groove 11 provided on the plate 5. The rivet nut body 3 is composed of a fixed column 1 and a deformation column 2. The fixed column 1 and the deformation column 2 are integrally formed. The middle parts of the fixed column 1 and the deformation column 2 are both hollow structures. An internal thread 6 is provided on the inner wall of the fixed column 1. A plurality of vertically arranged first anti-slip grooves 8 are provided on the outer wall of the deformation column 2. The first anti-slip groove 8 extends downward from the top of the deformation column 2 to the middle part. The plurality of first anti-slip grooves 8 The plurality of second anti-slip slits 9 are evenly spaced apart, and strip plates 7 are fixedly connected to the outer wall of the deformation column 2 below the plurality of first anti-slip slits 8. The cross section of the strip plate 7 at one end away from the deformation column 2 is set to a V-shaped structure. The upper end of the deformation column 2 is provided with a nut cap 4 integrally formed therewith. The nut cap 4 is an annular plate structure. The bottom of the nut cap 4 is provided with a plurality of second anti-slip slits 9. The plurality of second anti-slip slits 9 are distributed in a ring shape with the axis of the nut cap 4 as the center. The plurality of second anti-slip slits 9 are evenly spaced apart, and the bottom of the nut cap 4 is also fixedly connected with a plurality of fixing spikes 10.

[0021] Working principle of the rivet nut body 3: insert the rivet nut body 3 into the mounting groove 11 of the plate 5, then insert the bolt into the interior of the rivet nut body 3, and turn the bolt to move the fixing column 1 of the rivet nut body 3 upward, so that the deformation column 2 begins to deform. Figure 4 At this time, the deformation column 2 and the nut cap 4 will clamp the plate 5, thereby fixing the rivet nut body 3 on the plate 5. The above principle is the prior art.

[0022] Wherein, the fixing spike 10 is made of hard alloy.

[0023] Such an arrangement can ensure that the fixing spike 10 will not be deformed when it is inserted into the plate 5.

[0024] The utility model provides an anti-slip rivet nut, and the specific working principle is as follows:

[0025] During the installation of the rivet nut body 3, the multiple first anti-slip grooves 8 on the outer wall of the deformation column 2 will increase the friction between the deformation column 2 and the inner wall of the installation groove 11, forming an anti-slip effect. The deformation column 2 and the strip plate 7 on the outer wall will contact the bottom of the plate 5 and embed into the interior of the plate 5, thereby forming a second anti-slip effect. The second anti-slip groove 9 at the bottom of the nut cap 4 will increase the friction between the nut cap 4 and the top of the plate 5, thereby forming a third anti-slip effect. At the same time, the fixed thorns 10 at the bottom of the nut cap 4 will penetrate into the interior of the plate 5, forming a fourth anti-slip effect. The multi-layer anti-slip measures can effectively improve the firmness between the rivet nut body 3 and the plate 5, and avoid slipping of the rivet nut body 3 after installation.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
