Problems solved by technology

[0005] The purpose of the present invention is to provide a lock nut with a wedge-shaped block set on the side of the nut, which solves the problem that some existing wedge-shaped blocks are embedded in the side wall of the nut, which is difficult to operate because of its small size, and it is relatively difficult to disassemble the nut. Difficulty pulling out the wedge

Abstract

The invention discloses a lock nut with a wedge-shaped block external member on the side surface and relates to the field of lock nuts. The lock nut comprises a bolt and a nut, the nut is in threaded connection with the peripheral side face of the bolt, a positioning part is fixedly installed at the bottom of the nut, a threaded hole penetrating through the positioning part is formed in the upper surface of the positioning part, and the positioning part is in threaded connection with the peripheral side face of the bolt through the threaded hole. A first movable groove is formed in the positioning part and communicates with the threaded hole, a movable column is movably sleeved with the first movable groove, a wedge-shaped positioning block is fixedly connected to the end, close to the threaded hole, of the movable column, a wedge-shaped extrusion block is fixedly connected to the other end of the movable column, and the wedge-shaped extrusion block penetrates through the side wall of the positioning part and extends out of the positioning part. According to the lock nut with the wedge-shaped block external member on the side surface, the wedge-shaped extrusion block is pushed to be clamped into a thread on the peripheral side face of the bolt, the bolt can be jacked tightly, and the nut is not prone to loosening.

Description

technical field [0001] The invention belongs to the technical field of anti-loosening nuts, in particular to an anti-loosening nut with a wedge-shaped block set on the side of the nut. Background technique [0002] The working principle of the nut is to use the friction between the nut and the bolt for self-locking, but the reliability of this self-locking will be reduced in the dynamic load. If the fastener is in a heavy-duty and vibrating working environment, it is easy to There is looseness. [0003] Fasteners in heavy-duty and vibrating working environments generally use wedges to lock the nuts. However, wedges are generally embedded in the side walls of the nuts. Their small size makes it difficult to operate, and the nuts need to be disassembled It is difficult to pull out the wedge-shaped block, which does not meet the use requirements. [0004] In order to solve the above problems, the present invention proposes a lock nut with a wedge set on the side of the nut. ...
