Abstract
The utility model discloses a nut capable of preventing invalidation. The nut comprises a nut main body, wherein the nut main body is composed of a first nut and a second nut; the second nut is located above the first nut; the outer diameter of the second nut is smaller than that of the first nut; a screw thread through hole is formed inside the nut main body; a round disc is connected to the bottom of the first nut; the center of the round disc is sunk inwards while the edge thereof stretches outwards along the center of the round disc to form a trumpet shape. The first nut and the second nut are arranged, and the nut can be screwed or unscrewed by using a wrench to clamp the second nut when corner angles of the nut are abraded, so that the invalidation of the nut caused by abraded corner angles is prevented, and the service life is increased; the round disc connected to the bottom of the nut is deformed elastically during the screwing process, the deformation force can prevent the nut after being screwed against looseness, and a clamping claw on the round disc is clamped into a surface of a part during the screwing process, so that the connection between the nut and the part is enabled to be firmer, and a washer is no longer needed in the use process.
Description
Technical field
The utility model relates to a kind of nut that can anti-inefficacy, belongs to nut technical field.
Background technique
Existing nut in use, is often tightened or is unscrewed by instruments such as spanners, uses for a long time six corner angle of back nut to be gradually worn, and uses the instruments such as spanner cannot clamp nut, also just cannot be tightened or unscrew.Particularly in field of aerospace, the nut specification of using wants high a lot of than plain nut, its cost is also relatively high, if only because the corner angle of nut are worn just replaced, its waste is also larger, and existing nut in use, all needs Passscheiben to use, to increase its frictional force, but it is cumbersome to be inserted in packing ring process.
Summary of the invention
The purpose of this utility model is: a kind of nut that can anti-inefficacy is provided, solves existing nut after corner angle are worn, the problem such as be difficult to tighten or unscrew.
The technical solution of the utility model: a kind of nut that can anti-inefficacy, include nut body, this nut body is comprised of the first nut and the second nut, the second nut is positioned at the first nut top, the external diameter of the second nut is less than the external diameter of the first nut, is provided with tapped through hole in nut body, and the first nut bottom is connected with a disk, this circle disk center inwardly sinks, and its edge is protruding along circle centre position is horn mouth shape.
Above-mentioned nut that can anti-inefficacy, the edge of described disk is evenly equipped with claw.
Above-mentioned nut that can anti-inefficacy, described the second nut thickness is 0.6～1.2 times of the first nut thickness.
The beneficial effects of the utility model: the utility model is provided with the first nut and the second nut, in using process, after the corner angle of the first nut are worn, use tool holder second nuts such as spanner or to unscrew this nut screwing clamping, prevented that nut from causing its inefficacy because corner angle are worn, increased the working life of nut, in the first nut bottom, be connected with disk, on disk, be provided with claw, in rundown process, disk generation resiliently deformable, this elastic deformation force can prevent from occurring becoming flexible after nut screwing clamping, claw on disk snaps in part surface in rundown process simultaneously, make nut more firm with being connected of part, in using process, no longer need to use packing ring.
Accompanying drawing explanation
Accompanying drawing 2 is side structure schematic diagram of the present utility model
Reference character: 1-the first nut, 2-the second nut, 3-tapped through hole, 4-disk, 5-claw.
Embodiment
Embodiment of the present utility model: a kind of nut that can anti-inefficacy, as shown in accompanying drawing 1-2, include nut body, this nut body is comprised of the first nut 1 and the second nut 2, and the second nut 2 is positioned at the first nut 1 top, and the external diameter of the second nut 2 is less than the external diameter of the first nut 1, in nut body, be provided with tapped through hole 3, the first nut 1 bottom is connected with a disk 4, and the center of circle of this disk 4 inwardly sinks, and its edge is protruding along circle centre position is horn mouth shape.
At described disk 4 edges, be evenly equipped with a plurality of claws 5.
In working process, the second nut 2 thickness are 0.6～1.2 times of the first nut 1 thickness.What because main, use is that the first nut 1, the second nut 2 is used under the first nut 1 failure conditions, therefore that its thickness need not arrange is too thick, in order to avoid waste material improves cost of production.Too thin, insufficient strength during use, and highly too low being difficult to clamp.
In nut screwing clamping process, first the edge that is disk 4 contacts with part surface, along with being constantly screwed into, circle disk center is gradually near part surface, and in rundown process, resiliently deformable can occur disk 4, and this elastic deformation force can fix nut body well, avoid nut body loosening, and in rundown process, the claw 5 on disk 4 edges can snap in part surface, make nut body more firm with being connected of part.After long-term use, the corner angle of the first nut 1 can be worn gradually, use spanner to be difficult to tighten or unscrew nut body, now, use spanner to clamp the second nut 2 and can tighten or unscrew nut.
