Efficient locking nut and assembling and disassembling method thereof

Abstract

The invention provides an efficient locking nut and an assembling and disassembling method thereof, and belongs to the field of mechanical accessories. The problems that an existing fastener is troublesome to assemble and disassemble and poor in anti-loosening effect are solved; the efficient locking nut is matched with a bolt to be used for fixing a connected piece, the bolt comprises a screw rodand a bolt head, the nut comprises a screw barrel and a clamping sleeve arranged on the screw barrel in a sleeving mode, a plate groove is formed in the inner wall of the screw barrel, and a first clamping plate and a second clamping plate are arranged in the plate groove; an inner screw groove is formed in the inner arc face of the first clamping plate, an outer blocking edge is arranged on theouter wall of the bottom end of the clamping sleeve, an inner blocking edge is arranged on the inner wall of the top end of the clamping sleeve, a compression spring is arranged between the inner blocking edge and the top end of the screw barrel, the first clamping plate and the second clamping plate are made of hard materials, a rubber anti-loosening pad is fixed to the inner arc face of the second clamping plate, a first radial moving mechanism is arranged between the first clamping plate and the clamping sleeve, and a second radial moving mechanism is arranged between the second clamping plate and the clamping sleeve. The locking nut is efficient and convenient to disassemble and assemble and better in anti-loosening effect.

Description

technical field

[0001] The invention belongs to the technical field of mechanical accessories, and relates to a high-efficiency locking nut and an assembly and disassembly method thereof. Background technique

[0002] Fasteners are a common mechanical accessory, usually including bolts and nuts that are screwed together. However, before the nuts and bolts are tightened, the idle rotation of the nuts on the bolts will waste assembly and disassembly time and affect assembly and disassembly efficiency.

[0003] The existing application number is 201910662061.7, which is a Chinese invention patent application titled "A Fast Self-Locking Nut Structure and Its Assembly and Using Method". It sets an outer locking groove on the outer wall of the nut sleeve and installs a lock on the outer locking groove. Tight sleeve, there is a main displacement mechanism between the main nut piece and the locking sleeve that plays the role of screw connection, and an auxiliary displacement mechani...
