Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses establish flange pad, annular lug respectively at nut body both sides end to add limit structure and further spacing to the bolt of being connected with it, guaranteed the stopping effect, reduced between bolt and the nut because of the vibration produces not hard up possibility.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic top view of the structure of FIG. 1;

in the figure: the nut comprises a nut body 1, a flange pad 2, a screw hole 3, an annular lug 4, an upper section 41, a lower section 42, a groove 5, an embedded groove 51 and an opening 6.

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.

As shown in fig. 1 and 2, a fastener with a retaining function comprises a nut body 1, a flange pad 2 is arranged at one side end of the nut body, a through screw hole 3 is formed in the middle of the nut body and the flange pad, an annular convex block 4 protruding out of the nut body is arranged at the other side end of the nut body, and a limiting structure (not shown in the figure) is arranged on the inner side wall of the annular convex block. Set up limit structure and rotate spacingly to the bolt of spiro union, and then realized the stopping effect, guaranteed to connect stably, prevented not hard up between bolt and nut.

Further, the annular bump 4 comprises an upper section 41 and a lower section 42, the lower section is close to the nut body, a thread is arranged on the lower section, the thread and a thread on a screw hole formed in the middle of the nut body and the flange pad are integrally formed, and the limiting structure is arranged on the upper section. The annular convex block is also provided with threads, so that the stability of the connection of the annular convex block during bolt connection is ensured. The upper segment cross-section is the L type, the vertical portion inside wall fixed connection limit structure of upper segment, and limit structure is the elastic component, and the elastic component transversely protrudes in the horizontal part of upper segment, the screw thread of hypomere. The bolt is clamped and limited by the elastic piece, and the stopping effect of bolt-nut connection is enhanced.

The recess 5 that vertical portion was run through to a plurality of levels has been seted up downwards to the vertical portion up end of upper segment 41, and relative division is equipped with embedding portion 51 on two cell walls of recess, and the embedding is provided with the locating plate in the embedding portion, also can set up the elasticity cushion in the embedding portion, carries out effectively spacingly to the locating plate. The positioning plate is fixed with an arc-shaped elastic piece which can be an elastic cushion, and a plurality of elastic pieces surround to form a circle.
