Abstract

The invention discloses a lock nut. The locking nut comprises a nut body; a bolt is arranged in the nut body; the nut body is in threaded connection with the bolt; a threaded hole is formed in one side of the nut body; a sliding groove is formed in the end, close to the bolt, of the threaded hole, a threaded block is arranged in the threaded hole, the threaded block is in threaded connection withthe threaded hole, a cutting block is slidably connected into the sliding groove, a knife edge is arranged at the end, close to the bolt, of the cutting block, and a U-shaped frame is fixedly installed on the side, close to the cutting block, of the threaded block. By driving the threaded block to rotate, the threaded block is made to continuously move inwards through threaded connection between the threaded block and the threaded hole, then the cutting block is pushed to move inwards, the knife edge end of the cutting block can be cut into a bolt thread under the pressure of the threaded block, rotating fixing of the nut body is achieved, and loosening of the nut body is avoided.

Description

technical field [0001] The invention relates to the technical field of metal fittings, in particular to a locknut. Background technique [0002] Bolts and nuts are mechanical parts. Bolts are a type of fastener consisting of a head and a screw (cylindrical body with external threads). They are usually used in conjunction with nuts to fasten two Parts, this connection form is called bolt connection, if the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection; [0003] The prior art has the following disadvantages: when the nut is used, loosening often occurs, which poses a great potential safety hazard. Contents of the invention [0004] The purpose of the present invention is to provide a kind of anti-loosening nut, by driving the threaded block to rotate, and then using the threaded connection between the threaded block and the threaded hole, the threaded block is continuously moved inward, and then the cut blo...
