Abstract

The utility model discloses a locknut, which comprises a screw rod and a nut body, wherein the screw rod is provided with an axial non-return clamping groove; the nut body includes joint portion and the spiro union portion with joint portion integrated into one piece, set up the T-slot that a plurality of clockwise circumference slopes evenly arranged in the joint portion, every the T-slot joint has T type shell fragment, the T-slot is stretched out to the tip of T shape shell fragment to with non return draw-in groove cooperation joint. The T-shaped elastic sheet is clamped into the non-return clamping groove to block the line of the nut body, so that the screw cannot be loosened or dropped by self under high-frequency vibration, the use safety of equipment can be well guaranteed, and great damage caused by screw slippage is greatly reduced. The utility model discloses after mass production, the application usage is wide, can be used to unmanned equipment, mining machinery, agricultural machine, industrial equipment, aerospace equipment application etc. are the product that present market is urgently needed.

Description

Anti-loose nut

Technical Field

The utility model relates to a fastener technical field specifically is a locknut.

Background

In daily life, people often find that under a normal movement working state, a nut locked mechanically can generate a self-loosening effect due to mechanical vibration; to solve these problems, our predecessors invented the method of using a rigid spring washer, which can effectively reduce the self-slipping effect of the screw under slight vibration.

In the present day of 21 century, along with the development of scientific progress and the increasing particularity of the working conditions of equipment, the conventional anti-slip screw locking device is far from meeting the slipping phenomenon that vibration between the screw and the nut is loosened slowly under high-frequency vibration until the nut jumps out of the screw.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a locknut to solve at least one of the problem that proposes in the above-mentioned background art.

A locknut comprises a screw and a nut body, wherein an axial non-return clamping groove is formed in the screw; the nut body includes joint portion and the spiro union portion with joint portion integrated into one piece, set up the T-slot that a plurality of clockwise circumference slopes evenly arranged in the joint portion, every the T-slot joint has T type shell fragment, the T-slot is stretched out to the tip of T shape shell fragment to with non return draw-in groove cooperation joint.

Furthermore, the outer side of the clamping portion is provided with a nut upper cover clamped with the nut body.

Further, the number of the check clamping grooves is 1 or more.

Furthermore, the number of the T-shaped grooves and the number of the T-shaped elastic sheets are respectively 6.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses well screw rod is screwed up clockwise with the nut body, and the T shape shell fragment tip that stretches out the T-slot receives the power that is close to the screw rod all the time. When the nut rotates anticlockwise, the end part of the T-shaped elastic sheet is clamped into the non-return clamping groove, and the nut body cannot rotate anticlockwise. T shape shell fragment has blockked the route of nut body pine back, makes the screw rod can not produce the pine back again by oneself or the condition that drops under high frequency vibrations, and the safety in utilization of assurance equipment that can be fine has reduceed the major hazard because of the screw slippage produces greatly. The utility model discloses after mass production, the application usage is wide, can be used to unmanned equipment, mining machinery, agricultural machine, industrial equipment, aerospace equipment application etc. are the product that present market is urgently needed.

In the figure: 1-a screw; 2-a non-return clamping groove; 3-a nut body; 301-a threaded connection; 302-a clamping portion; 303-T-shaped slot; 4-upper nut cover; 5-T-shaped elastic sheet.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-2, a locknut comprises a screw and a nut body, wherein the screw is provided with an axial non-return clamping groove; the nut body includes joint portion and the spiro union portion with joint portion integrated into one piece, set up the T-slot that a plurality of clockwise circumference slopes evenly arranged in the joint portion, every the T-slot joint has T type shell fragment, the T-slot is stretched out to the tip of T shape shell fragment to with non return draw-in groove cooperation joint.

The outside of joint portion is equipped with the nut upper cover with the nut body joint, and the upper cover can prevent that T shape shell fragment from the T-arrangement groove.

The number of the non-return clamping grooves is 1 or more, and the number of the T-shaped grooves and the number of the T-shaped elastic sheets are 6 respectively.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
