Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, an embodiment of the present invention is shown: a fastening nut capable of enhancing extrusion force comprises a nut body 1, a locking gasket 4, circular through holes 5 and wedge-shaped grooves 6, wherein threaded holes 2 are formed in the nut body 1, rigid springs 8 are mounted at the bottom of the nut body 1, eight rigid springs 8 are uniformly arranged, the rigid springs 8 are fixedly mounted on the periphery of the bottom end of the nut body 1, wedge-shaped sliding blocks 7 are fixedly mounted at the bottom ends of the rigid springs 8, and the bottom ends of the wedge-shaped sliding blocks 7 are of arc-shaped structures;
the upper end surface of the wedge-shaped groove 6 and the position corresponding to the bottom of the wedge-shaped sliding block 7 are uniformly provided with the wedge-shaped groove 6, and the bottom end of the wedge-shaped groove 6 is of an arc structure; the nut body 1 is a hexagonal nut, so that the nut is convenient to screw and install; the side wall of the nut body 1 is uniformly provided with the strip-shaped grooves 3, so that the nut body 1 can be installed in an environment with large temperature change, and the nut body 1 is prevented from cracking caused by expansion with heat and contraction with cold; the top end of the rigid spring 8 is fixedly welded and installed at the bottom end of the nut body 1, and the bottom end of the rigid spring 8 is fixedly welded and installed at the top end of the wedge-shaped sliding block 7; the wedge-shaped groove 6 and the wedge-shaped sliding block 7 are installed in a matched mode, so that the wedge-shaped sliding block 7 is conveniently installed in the wedge-shaped groove 6 in a matched mode; the diameter of the round through hole 5 is larger than that of the threaded hole 2, so that a bolt can conveniently penetrate through the round through hole 5; the bottom of the locking gasket 4 is provided with anti-slip threads, so that the friction force between the locking gasket 4 and the part to be installed is increased conveniently.
