Abstract
The utility model relates to a mechanical connection technical field specifically is an anti -loosening and anti -theft nut, and the screw has been offered at the nut center, and the nut includes top nut, lower nut, is equipped with a plurality of oblique type teeth under the top nut on the terminal surface, relatively, is equipped with on the lower terminal surface of top nut rather than corresponding a plurality of oblique type tooth, the screw border of lower nut up end is equipped with the round boss, is equipped with a plurality of flutings on the boss, and relatively, the screw border of terminal surface is equipped with the recess that can hold this boss under the top nut, and the inner wall of recess is for setting up in the slant, and the recess is linked together with the screw and the diameter of recess is greater than the diameter of screw. The utility model discloses can prevent that the nature is not hard up and pull to twist and steal to have remarkable locking, theftproof function. Simple structure, low cost, need not specialized tool, the batch production of being convenient for.
Description
[technical field]
The utility model relates to mechanical connecting element technical field, specifically a kind of anti-loose anti-theft nut.
[background technique]
Hexagon nut is divided into I type, II type and slim three kinds according to nominal thickness.The nut of more than 8 grades is divided into 1 type and II type two profiles formula.Hexagon nut and bolt, screw fit use, and play and connect fastening mechanism effect.Wherein most widely used through I type hexagon nut, I type nut divides A again, B, C tri-grades.Machine, equipment or structure that C level nut is more coarse for surface ratio, not high to required precision; A level and B level nut is brighter and cleaner for surface ratio, machine, equipment or the structure higher to required precision.The thickness of II type hexagon nut is thicker, is used for the occasion that Chang Jingchang needs mounting or dismounting.The thinner thickness of hexagon thin nut, is used for being connected the restricted occasion of space surface of parts.
In the industrial fields such as mechanized equipment, wind-powered electricity generation steel tower, petroleum pipeline, railroad bridge, usually all can coordinate each component fastening with nut.And flow of metal formula lock nut of the prior art or nonmetal embedded lock nut only have anti-loosening property, lack necessary anti-theft feature.
[model utility content]
The purpose of this utility model cannot have anti-loosening property, theftproof performance to solve plain nut in prior art exactly simultaneously, or this defect that its impact of performance is poor, the anti-loose anti-theft nut of a kind of novel structure, safe and reliable, stable performance is provided, nut center offers screw, nut comprises upper cap nut, lower nut, upper cap nut lower end surface is provided with some oblique type teeth, and relatively, the lower end surface of upper cap nut is provided with some oblique type tooth corresponding thereto; The screw edge of lower nut upper-end surface is provided with a circle boss, boss is provided with some flutings, relatively, is provided with the groove that can hold this boss at the screw edge of upper cap nut lower end surface, the inwall of groove is oblique interior setting, and groove is connected with screw and the diameter of groove is greater than the diameter of screw.
Boss hem width on diameter difference between the bottom portion of groove of described upper cap nut lower end surface and its screw >=lower nut upper-end surface.
The projection cube structure on described oblique type tooth to be top be inclined-plane.
Described fluting quantity is 6.
Compared with the existing technology, its advantage is that the utility model can prevent nature from loosening and twisting theft to the utility model, has remarkable locking, anti-theft feature.Structure is simple, with low cost, without the need to special tool, be convenient to batch production.

[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model is a kind of anti-loose anti-theft nut, as shown in Fig. 1 ~ Fig. 2, comprises upper cap nut and lower nut two-part composition.The fluting boss of lower nut and the groove fit of upper cap nut, groove makes boss stress deformation, drives the internal thread at same position to be out of shape simultaneously, serves the effect that locking is locking.The oblique type tooth of the upper-end surface oblique type tooth of lower nut and the lower end surface of upper cap nut coordinates, all linked with one another between tooth and tooth, serves the effect of retaining.The retaining effect effect that exactly available protecting locking is locking, thus serve antitheft effect.
As shown in Figure 3, first lower nut is screwed in bolt or stud, uses corresponding mounting torque to be carried out by parts tightening fixing.As shown in Figure 4, then upper cap nut is screwed in bolt or stud, when the lower end surface groove being screwed into upper cap nut makes it the Contact with the upper-end surface boss of its lower nut.As shown in Figure 5, the lower end surface groove continuing to be screwed into upper cap nut makes it with the upper-end surface boss of its lower nut toward interior stress deformation, and when upper cap nut is screwed into gradually near lower nut, the internal thread at this position, simultaneously toward interior stress deformation, plays locking locking functions.As shown in Figure 6, the lower end surface groove continuing to be screwed into upper cap nut makes it with the upper-end surface boss of its lower nut toward interior continuous stress deformation, improve locking locking functions, until the oblique type tooth contact of the oblique type tooth of upper cap nut lower end and lower nut upper end also coordinates mutually completely, the oblique type tooth at this position is all linked with one another, can only cannot unscrewed along twisting, play retaining anti-theft feature.
