Novel lock nut

Abstract

The invention discloses a novel lock nut which comprises a nut body. A threaded hole is formed in the nut body. The nut further comprises two L-shaped rotary blocks, the bottom of the I portion of each L-shaped rotary block is a circular bead, the inner end face of the - portion of each L-shaped rotary block is provided with multiple protrusions, the nut body is symmetrically provided with two horizontal grooves communicated with the outside, the nut body is further provided with vertical containing grooves communicated with the horizontal grooves, the I portion of each L-shaped rotary blocks are is contained in the corresponding containing groove, the width of the horizontal grooves is larger than the width of the L-shaped rotary blocks, the I portions of the L-shaped rotary blocks can slide up and down in the containing grooves and can turn over downward after sliding to the highest position, and the - portion of each L-shaped rotary block comprises a fixing block, a connection block and a cylinder. When not used, the novel lock nut has no difference with a commonly used nut, and the lock nut is little in occupied space, convenient to carry and use, capable of being used as common nuts and multifunctional.

Description

technical field [0001] The invention relates to a novel anti-loosening nut, in particular to a novel anti-loosening nut used on plates, and belongs to the technical field of mechanical fasteners. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening, and is used to fasten and connect two mechanical parts with through holes. If the bolt is unscrewed from the nut, the two parts can be separated, so the connection is a detachable connection, and can also be widely used on plates. When the mechanical equipment is running, it will inevitably produce mechanical vibration. Long-term mechanical vibration will cause the nut to shake, lead to thread wear, and make the fastening effect worse, affecting the working performance and stability of the mechanical equipment, especially affecting some precision equipment. Machining accuracy, there may also be a phenomenon that the bolt escapes from the threaded hole of the nut, whic...

When the mechanical equipment is running, it will inevitably produce mechanical vibration. Long-term mechanical vibration will cause the nut to shake, lead to thread wear, and make the fastening effect worse, affecting the working performance and stability of the mechanical equipment, especially affecting some precision equipment. Machining accuracy, there may also be a phenomenon that the bolt escapes from the threaded hole of the nut, which may cause mechanical failure
