Abstract
The utility model discloses a kind of clamping bead type Anti-slip nut, comprise tapped hole, nut body, it is characterized in that: also comprise card bead groove, described nut body is regular hexagon cylinder, described tapped hole is positioned at nut body inside, two card bead grooves are provided with in described nut body, described two card bead grooves opposition distribution, described card bead groove is irregularity shape cylinder, cross section is made up of two limits, near tapped hole limit overlap with tapped hole circumference sideline, another side and lean on into tapped hole limit with starting point be 3 ° of angles arcuately track away from tapped hole.The utility model by being provided with card bead groove in nut body, ball is put into when nut coordinates with screw rod, in nut process, ball can normally roll in card bead groove, when unscrewing in the other direction ball with screw deadlocking thus when broken talk about destroy needed for clamp structure surface play the anti-skidding effect of nut.
Description
[technical field]
The utility model relates to MACHINERY JOINT field, the technical field of particularly mechanical whorl connection.
[background technique]
At present, in general fastening piece component, nut is the common and component widely of a kind of purposes.But nut is when sharp pounding and irregular brute force fluctuation, often there will be the phenomenon loosening and come off.Usually measure that is anti-skidding and Drop-proof is taked to be generally adopt install elastic washer additional or directly do anti-skidding process in nut axial end surface, the former needs extra installation, not only cost improves but also installs inconvenience, the surperficial required clamp structure surface of salient point press-in just must can be reached skidproof effect by the latter in normal operation, so can damage component surface.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of clamping bead type Anti-slip nut, can realize playing the anti-skidding effect of nut when not destroying required clamp structure surface.
For achieving the above object, the utility model proposes a kind of clamping bead type Anti-slip nut, comprise tapped hole, nut body, it is characterized in that: also comprise card bead groove, described nut body is regular hexagon cylinder, described tapped hole is positioned at nut body inside, two card bead grooves are provided with in described nut body, described two card bead groove opposition distributions, described card bead groove is irregularity shape cylinder, cross section is made up of two limits, overlap with tapped hole circumference sideline near tapped hole limit, another side with lean on into tapped hole limit with starting point be 2 ° of angles arcuately track away from tapped hole, the upper and lower planar surface of described card bead groove lays respectively on the axial Transverse plane of described nut body, apart from nut body the other end plane 3mm place.
As preferably, the embedding nut body of described card bead groove is nut direction by being deep to shallow direction.
As preferably, be provided with internal thread in described tapped hole, screw thread is regular screw threads.
As preferably, described card bead groove and ball engagement, ball diameter is 2/2 of the degree of depth of card bead groove insert nut body.
As preferably, described tapped hole has chamfering in planar ends car.
The beneficial effects of the utility model: the utility model by being provided with card bead groove in nut body, ball is put into when nut coordinates with screw rod, in nut process, ball can normally roll in card bead groove, when unscrewing in the other direction ball with screw deadlocking thus when broken talk about destroy needed for clamp structure surface play the anti-skidding effect of nut.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is a kind of clamping bead type Anti-slip nut of the utility model shaft side figure;
Fig. 2 is a kind of clamping bead type Anti-slip nut of the utility model plan view;
Fig. 3 is a kind of clamping bead type Anti-slip nut of the utility model plan view.
[embodiment]
Consult Fig. 1, Fig. 2 and Fig. 3, the utility model, comprise tapped hole 2, nut body 3, it is characterized in that: also comprise card bead groove 1, described nut body 3 is regular hexagon cylinder, it is inner that described tapped hole 2 is positioned at nut body 3, two card bead grooves 1 are provided with in described nut body 3, described two card bead grooves 1 oppose and distribute, described card bead groove 1 is irregularity shape cylinder, cross section is made up of two limits, overlap with tapped hole 2 circumference sideline near tapped hole 2 limit, another side with lean on into tapped hole 2 limit with starting point be 2 ° of angles arcuately track away from tapped hole 2, described card bead groove about 1 planar surface lays respectively on the axial Transverse plane of described nut body 3, apart from nut body 3 the other end plane 3mm place.The embedding nut body of described card bead groove 13 is nut direction by being deep to shallow direction.Be provided with internal thread in described tapped hole 2, screw thread is regular screw threads.Described card bead groove 1 and ball engagement, ball diameter is 2/2 of the degree of depth of card bead groove 1 insert nut body 3.Described tapped hole 2 has chamfering in planar ends car.
Utility model works process:
A kind of clamping bead type Anti-slip nut of the utility model in the course of the work, by passing through to be provided with card bead groove in nut body, ball is put into when nut coordinates with screw rod, in nut process, ball can normally roll in card bead groove, when unscrewing in the other direction ball with screw deadlocking thus when broken talk about destroy needed for clamp structure surface play the anti-skidding effect of nut.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
