Multifunctional fastening part and use method thereof

Abstract

The invention provides a multifunctional fastening part and a use method thereof, and belongs to the field of mechanical accessories. The problems that an existing fastening part is low in efficiencyduring construction, troublesome in use and single in function are solved. The multifunctional fastening part comprises a bolt and a nut, the bolt comprises a screw rod and a screw head, the wall of the screw rod is provided with a clamping groove, the inner wall of the top end of the nut is provided with a sleeve groove, a clamping sleeve in the sleeve groove is further included, a clamping blockis mounted on the inner wall of the clamping sleeve, a limiting groove is formed in the outer wall of the clamping sleeve, the position, close to the upper side groove wall, of the limiting groove isan anti-theft segment, the position, close to the lower side groove wall, of the limiting groove is a loosening-prevention segment, a rod groove is formed in the wall of the sleeve groove, an elasticrod is mounted in the rod groove, a reset spring is mounted between the outer end of the elastic rod and the bottom of the rod groove, and pushes the elastic rod, and a limiting block is formed on the inner end of the elastic rod. The fastening part can be adjusted according to needs, the anti-loosening or anti-theft effect is achieved, and the use is convenient and efficient.

Description

technical field [0001] The invention belongs to the technical field of mechanical accessories, and relates to a multifunctional fastener and a using method thereof. Background technique [0002] Fasteners include bolts and nuts that are screwed together. They are used to fasten parts and are common mechanical accessories. For machines that require frequent vibrations, it is usually necessary to make the fasteners have a certain anti-loosening ability to prevent the nuts from loosening and falling off. lead to danger. [0003] The existing application number is 201610876624.9, and the Chinese invention patent titled "Fastener to Prevent Nut from Falling off" has an axial groove on the bolt, and an arc-shaped notch on the screw hole of the nut, and the arc-shaped There are several tooth grooves in the notch; after the nut is installed in place, insert a locking bar into the groove of the bolt, so that the locking teeth of the locking bar engage with the tooth grooves of the n...

AI Technical Summary

Problems solved by technology

[0004] 1. It is necessary to install the locking bar after the nut is installed in place on the bolt, and the locking bar needs to be installed in the groove of the bolt, and at the same time, the locking teeth of the locking bar need to mesh with the tooth grooves of the notch of the nut, so the construction is troublesome Very low efficiency;

[0005] 2. In order to make the lock teeth of the locking bar mesh with the slots of the nut slot after the nut is rotated at any position on the bolt, the number of slots must be as large as possible and must be full of the screw holes of the nut, but the screw There must be an internal thread in the hole, and it is impossible to cover the screw hole with the tooth groove, so when the groove and the notch are misaligned, the locking strip cannot be installed at all;

[0006] 3. And the fastener can only be used as an anti-loose fastener, and in some occasions, not only anti-looseness is required, but also anti-theft may be required, and anti-theft can be divided into detachable anti-theft and non-detachable anti-theft, so the fastening Firmware is limited in scope
