Double-slotted self-locking nut

Abstract

The invention discloses a double-slotted self-locking nut. The double-slotted self-locking nut comprises a nut body, wherein a convex cylindrical object is arranged on one end surface of the nut body; a threaded hole which is interlinked with the threads on the nut body is formed in the cylindrical object; two symmetric slots which are vertical to the axis of the cylindrical object are formed in a cylinder of the cylindrical object; the depths of the slots are greater than the semicircle of the cylindrical object; the openings of the slots are extruded to deform along the axis of the cylindrical object; a butterfly-shaped gasket is arranged on the other end surface of the nut body; and a plurality of radial beads are arranged on the end surface of the gasket. When the double-slotted self-locking nut is screwed, the locking force is uniformly distributed on the threads and the meshing is tighter, so that the double-slotted self-locking nut is suitable for the application with more severe vibration and impact; through the setting of the butterfly-shaped gasket on the end surface, the anti-loose self-locking effect is more outstanding; and the self-locking nut is simple to mount, reusable, more convenient to dismount and more efficient.

Description

technical field [0001] The invention relates to a structure for connecting fasteners, which belongs to the technical field of machinery, and more specifically relates to a double-slotted self-locking nut. Background technique [0002] In the interconnection of connectors, threaded connection is very common and commonly used. At present, the anti-loosening method of threaded fastener connection is divided into three basic types: non-detachable anti-loosening, mechanical fastener anti-loosening and increased Anti-loosening with high friction. Non-removable anti-loosening is a method of anti-loosening that uses welding, bonding or punching point riveting to change a detachable threaded connection into a non-detachable threaded connection. The disadvantage is that threaded fasteners cannot be reused; mechanical fasteners The best anti-loosening method is to use mechanical fasteners to fix and pin the threaded parts and the connected parts or between the threaded parts and the t...

AI Technical Summary

Problems solved by technology

The method of adding cotter pins to bolts requires on-site assembly of cotter pins, which increases the workload and is inconvenient to disassemble when encountering problems

Ordinary nut plus stop washer requires on-site work for the angle and height of the washer, which is not easy to control

The anti-loosening effect of ordinary nuts plus flat washers and spring washers is not good
