An extruded slotted lock nut assembly

Abstract

The invention provides an extrusion type slotted locking nut assembly. The extrusion type slotted locking nut assembly comprises an extrusion type slotted locking nut assembly body. The extrusion typeslotted locking nut assembly body comprises an inner nut and an outer nut. The center of the nut body of the inner nut is provided with a through hole with internal threads, and the outer surface isprovided with external threads coaxial with the internal threads. The tail portion of the inner nut is provided with a special-shaped section, and the outer circumferential section of the special-shaped section is not a circular part coaxial with the internal threads. At least one slot is formed in the special-shaped section from the end surface to the interior. The outer nut is provided with second internal threads which can be matched and meshed with the external threads of the inner nut. The outer nut is provided with a locking section which can sleeve the special-shaped section of the inner nut. The smallest shaft through hole inner diameter of the locking section is larger than the smallest shaft through hole outer diameter of the special-shaped section and smaller than the largest shaft through hole outer diameter of the special-shaped section. The extrusion type slotted locking nut assembly is simple in structure and convenient to manufacture and install.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to an extrusion type slotted lock nut assembly. Background technique [0002] Fasteners are a type of mechanical parts used for fastening connections and are widely used. They can be seen in various types of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters, etc. Various fasteners. The purpose of fasteners is fastening. Once the fasteners loosen or fall off due to factors such as vibration and impact, it may cause equipment and machinery to lose their functionality, disintegrate, and even endanger personal safety. At present, more than 80% of the current mechanical equipment accidents are caused by the loosening of fasteners. [0003] In order to avoid various problems caused by the loosening of fasteners, technicians from various countries have continued to research and develop, and later there have been many methods to ...
