Abstract

The invention discloses a cushioned nut with a torsion bulge. The cushioned nut with the torsion bulge mainly comprises a hexagonal nut body, the bulge and a plunger. The exterior of the hexagonal nut body is of a hexagonal shape. Threads are formed inside the hexagonal nut body. A boss is arranged on the lower portion of the hexagonal nut body. The bulge is arranged inside the hexagonal nut body. A conical hole is designed in the center of the bulge. The plunger is arranged in the conical hole designed in the center of the bulge. The hexagonal nut body, the bulge and the plunger are located on the same center line. The cushioned nut with the torsion bulge does not loosen easily, is high in self-locking capacity, beneficial to mechanical operation, high in operation speed, simple in design, easy to manufacture, and low in cost.

Description

Technical field [0001] The invention relates to a nut, in particular to a nut with a pad with a torsional expansion plug. Background technique [0002] Some nuts with pads currently on the market are mostly smooth and flat and cannot be self-locking. Although nuts with pads increase the friction surface, they are easy to loosen. Some of them rely on spring pads to increase the self-locking ability, which is very inconvenient. Summary of the invention [0003] In order to make up for the shortcomings of the prior art and solve the problems that the nut with a pad is smooth and flat, cannot be self-locked, and the nut with a pad is easy to loosen, a nut with a torsion plug is designed. [0004] The technical solution of the present invention to solve its technical problems may be: [0005] The nut with a torsion expansion plug is mainly composed of a hexagonal nut, an expansion plug and a plunger. The hexagonal nut has a hexagonal shape on the outside, a thread on the inside, and a bos...
