Problems solved by technology
However, in actual use, it is often difficult for the installer to determine whether the nuts have been tightened in place, so it is difficult to ensure that the bolts and nuts will not loosen automatically during long-term use
And in some cases, the loosening and falling off of nuts can lead to serious accidents, resulting in major economic losses

The invention discloses a pressure point type all-metal lock nut. The pressure point type all-metal lock nut comprises a nut body and a boss located on one side of the nut body and is characterized inthat a threaded hole is arranged in the nut body and the boss along the central axis in a penetrating manner, the nut body is provided with a plurality of pressure points communicated with the threaded hole, the boss is provided with a plurality of pressure grooves, the pressure grooves are parallel with the central axis, and one ends of the pressure grooves penetrate one end, away from the nut body, of the boss. The pressure point type all-metal lock nut has the advantages that a to-be-fixed part squeezes arc-shaped protrusions to allow the nut body to deform along the pressure points, a bolt is locked by the aid of the deformation of the inner thread of the nut body, whether the nut is correctly fastened is determined by observing whether the arc-shaped protrusions are squeezed in a flush manner, the bolt is further locked by using a tool to transversely squeeze the boss to allow the inner thread of the boss to deform, and the problems of nut loosening and slipping under vibration can be solved effectively.
Description
technical field [0001] The invention relates to the technical field of nuts, in particular to the technical field of a pressure-point all-metal lock nut. Background technique [0002] There are three types of all-metal lock nuts, the first category is side pressure point all-metal lock nuts, the second category is end-face pressure point all-metal lock nuts, and the third category is all-metal lock nuts with locking plates. However, in actual use, it is often difficult for the installer to determine whether the nuts have been tightened in place, so it is difficult to ensure that the bolts and nuts will not loosen automatically during long-term use. And in some cases, the loosening and falling off of nuts can cause serious accidents and cause major economic losses. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a pressure point type all-metal lock nut, which can squeeze the arc-shaped protrusio...
