Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a press-riveting nut comprises a press-riveting nut body 1, wherein an annular boss 1-1, an inverted trapezoidal annular boss 1-2, an annular groove 1-3 and a flanging structure 1-4 are arranged on the press-riveting nut body 1, an outer gear ring 2 is arranged on the press-riveting nut body 1 in an interference fit manner, a round hole is formed in the press-riveting nut body 1, and a threaded sleeve 3 is connected to the round hole in an internal thread manner;

the inner wall of the round hole is provided with first internal threads 1-5, the thread sleeve 3 is provided with external threads 3-1, the external threads 3-1 are matched with the first internal threads 1-5, the inner wall of the thread sleeve 3 is provided with second internal threads 3-2, the rotating directions of the first internal threads 1-5 and the second internal threads 3-2 are opposite, the height of the circular boss 1-1 is 2.0-3.5mm, the height of the annular groove 1-3 is 4.0-5.5mm, a trapezoidal slow step is arranged between the circular boss 1-1 and the annular groove 1-3, one side of the outer gear ring 2, which is far away from the circular boss 1-1, is provided with a trapezoidal groove, when the press-riveting nut body 1 is used, the press-riveting nut body 1 is firstly plugged into the prefabricated hole of the plate until the press-riveting nut body 1 completely enters the prefabricated hole, the part that takes place deformation in the panel can be continuous enters into annular groove 1-3 in, and outer ring gear 2 can be tight block on the inner wall in prefabricated hole, then press rivet nut body 1 just tight with the prefabricated hole of panel tightly link together, because the second external screw thread 3-2 on the thread bush 3 is opposite with the direction of turning of the first internal thread 1-5 on the press rivet nut body 1 to the bolt can not take place not hard up when pressing rivet nut body 1 to link together, the utility model discloses simple structure can not take place not hard up in the middle of long-time use yet, very convenient in the middle of the in-service use.

The working principle is as follows: when using the pressure riveting nut body 1, will press riveting nut body 1 to plug into the prefabricated hole of panel earlier and wait to press riveting nut body 1 to enter into the prefabricated downthehole completely, the part that takes place deformation in the panel can be continuous enters into annular groove 1-3 in, and outer ring gear 2 can tightly block on the inner wall in prefabricated hole, so press riveting nut body 1 just tightly with the prefabricated hole of panel tightly link together, because the second external screw thread 3-2 on the thread bush 3 is opposite with the rotation of the first internal thread 1-5 on the pressure riveting nut body 1, thereby bolt and pressure riveting nut body 1 can not take place not hard up when linking together, the utility model discloses simple structure can not take place not hard up in the middle of long-time use yet, very convenient in the middle of the in-service use.
