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 efforts all belong to the protection scope of the present invention.

Examples

As shown in fig. 1 to 4, the anti-loosening rivet pressing fastener comprises a fastener body 1 and a threaded rod 5 positioned in the fastener body 1, wherein a screwing cap 2 is arranged at the upper end of the threaded rod 5, a spring 4 fixedly connected with the inner wall of the fastener body 1 is sleeved on the outer side of the threaded rod 5, and a rotating assembly 3 is arranged in the screwing cap 2;

the rotating assembly 3 comprises an annular groove 301 formed in the screwing cap 2, a circular ring 302 is rotatably connected in the annular groove 301, and the lower end of the circular ring 302 is fixedly connected with the spring 4.

As shown in fig. 1, fig. 2 and fig. 3, furthermore, the screwing cap 2 is provided with an annular limiting groove 303 communicating with the annular groove 301, and two limiting blocks 304 fixedly connected with the annular ring 302 are rotationally connected in the annular limiting groove 303, so that the arrangement of the limiting blocks 304 is convenient for limiting the annular ring 302 in the annular groove 301, and the annular ring 302 is prevented from being separated from the screwing cap 2.

As shown in fig. 1, 2, 3 and 4, a connection ring 305 is fixedly connected to the lower end of the circular ring 302, and the connection ring 305 is located between the outer wall of the threaded rod 5 and the inner wall of the spring 4, so that the spring 4 can be better controlled by the connection ring 305, and the situation that the spring 4 is extruded, deformed and dislocated is effectively reduced.
