Rapid self-locking type nut structure and assembly and application method thereof

Abstract

The invention provides a rapid self-locking type nut structure and an assembly and application method thereof, and belongs to the field of machine parts. The rapid self-locking type nut structure andthe assembly and application method thereof solve the problems that an existing nut is troublesome to assemble and disassemble and poor in anti-loose effect. The rapid self-locking type nut structurecomprises a nut sleeve, also comprises a sleeve-shaped locking sleeve, and further comprises a plurality of arc-shaped main nut sheets and auxiliary nut sheets, wherein the sleeve-shaped locking sleeve sleeves an outer locking groove in a matched mode, and the main nut sheets and the auxiliary nut sheets are located in the inner locking groove; the outer wall of the nut sleeve is in a regular hexagon shape; the inner wall of the nut sleeve is in a circular sleeve shape; the outer locking groove is formed in the outer wall, close to the top end, of the nut sleeve; the sleeve-shaped inner locking groove is coaxially formed in the middle of the inner wall of the nut sleeve; the outer wall of the locking sleeve is in a regular hexagon shape which is the same as that of the outer wall of the nut sleeve; inner threads are arranged on the inner arc surfaces of the main nut sheets and the auxiliary nut sheets; a main displacement mechanism is arranged between each main nut sheet and the locking sleeve; and an auxiliary displacement mechanism is arranged between each auxiliary nut sheet and the locking sleeve. The nut structure can be quickly disassembled and assembled, and meanwhile, the anti-loose effect is better.

Description

technical field [0001] The invention belongs to the technical field of mechanical accessories, and relates to a fast self-locking nut structure and an assembly and use method thereof. Background technique [0002] In the prior art, the mechanical device is usually fixed by means of the threaded cooperation between the bolt and the nut, but when the length of the bolt is long, the idling stroke of the nut will greatly waste the time for installation and disassembly. [0003] The application number is 201610672022.1, and the Chinese invention patent titled "A Quick Installation Nut" realizes the quick installation and disassembly of the nut by controlling the two thread sliders to move closer or apart. However, during the fastening process of mechanical equipment, Not only the nut needs to be installed and disassembled quickly, but also the shaking of the mechanical equipment will also cause the nut to loosen. Therefore, how to prevent the nut from loosening is also an urgent ...

Problems solved by technology

[0002] In the prior art, the mechanical device is usually fixed by means of bolts and nuts, but when the length of the bolt is long, the idling stroke of the nut will greatly waste the time for installation and disassembly

[0003] The application number is 201610672022.1, and the Chinese invention patent titled "A Quick Installation Nut" realizes the quick installation and disassembly of the nut by controlling the two thread sliders to move closer or apart. However, during the fastening process of mechanical equipment, Not only the nuts need to be installed and disassembled quickly, but the shaking of mechanical equipment will also cause the nuts to loosen. Therefore, how to prevent the nuts from loosening is also an urgent problem to be solved.

[0004] And in order to facilitate the screwing of nuts and bolts, there is generally a certain gap between the internal thread of the nut and the external thread of the bolt. After tightening, the relative tightening between the connected part and the nut is usually used to fix the nut. Therefore, the nut, bolt and connected part An overall anti-loosening structure is formed. Once the nuts and bolts are slightly loosened due to shaking, there will be a gap between the nuts and the connected parts, and the above-mentioned overall anti-loosening structure will fail, which in turn will lead to the loosening of the bolts.

[0005] The application number is 201510469397.3, and the Chinese invention patent titled "a detachable anti-loosening bolt or screw assembly". It sets a groove in the axial direction of the screw, and uses the groove to cooperate with the nut for positioning, so as to realize the connection between the nut and the screw. Relatively anti-loosening, but the grooves on the screw will affect the normal shape of the external thread on the screw and affect the normal screw connection
