Description

A kind of anti-loose self-tightening nut set

Technical field

This utility model relates to nut fastener applied technical field, a kind of anti-loose self-tightening nut set.

Background technology

In modern industry field, nut series products is largely used to locking mechanism part, but we also can find simultaneously, under many circumstances, excellent its is applied under vibrational state, we it is frequently necessary to the structural member locked is carried out periodic inspection reinforcing, prevents because the structure that nut loosening brings misplaces.

For above-mentioned this situation, in practical operation, people use various method to remove to fasten the nut locked, such as by super glue, and electric welding, perforation second consolidation etc., but so fundamentally go to solve the phenomenon of nut loosening displacement again without way.

Utility model content

The purpose of this utility model is to provide a kind of practical, anti-loose self-tightening nut set of use easy to spread, with the problem solving to propose in above-mentioned background technology.

For achieving the above object, the following technical scheme of this utility model offer:

A kind of anti-loose self-tightening nut set, including self-tightening nut body and self-tightening pad, it is provided with disjunctor lasso on described self-tightening pad, described self-tightening nut body is fastened in the inside of disjunctor lasso, the contact surface of described self-tightening nut body and self-tightening pad is the one or more helicoids seamlessly transitted, the helicoid of self-tightening nut body is the most corresponding with the helical angle of the helicoid of self-tightening pad, and the helicoid of self-tightening nut body coincide with the helicoid of self-tightening pad and contacts.

A kind of anti-loose self-tightening nut set, including self-tightening nut body and self-tightening pad, it is provided with disjunctor lasso on described self-tightening nut body, described self-tightening pad is fastened on disjunctor lasso, the contact surface of described self-tightening nut body and self-tightening pad is the one or more helicoids seamlessly transitted, the helicoid of self-tightening nut body is the most corresponding with the helical angle of the helicoid of self-tightening pad, and the helicoid of self-tightening nut body coincide with the helicoid of self-tightening pad and contacts.

As this utility model further scheme: described self-tightening pad and the contact surface of the object that is locked are pawl face, frosting or gold-plated emery face.

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

This utility model uses autofrettage, self-tightening nut body arranges a self-tightening structure, it is made after locking, to reach the effect of self-tightening, self-tightening nut body is allowed displacement no longer to occur or loosens, this utility model can be widely applied to Machine Design, processing and manufacturing industry, and has revolutionary using value in railway, bridge and building trade；Global design is novel, practical, it is easy to promote the use of.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.

Embodiment 1

Refer to Fig. 1-6, in this utility model embodiment, a kind of anti-loose self-tightening nut set, including self-tightening nut body 1 and self-tightening pad 2, it is provided with disjunctor lasso 3 on described self-tightening pad 2, described self-tightening nut body 1 is fastened in the inside of disjunctor lasso 3, the contact surface of described self-tightening nut body 1 and self-tightening pad 2 is the one or more helicoids seamlessly transitted, the helicoid of self-tightening nut body 1 is the most corresponding with the helical angle of the helicoid of self-tightening pad 2, and the helicoid of self-tightening nut body 1 coincide with the helicoid of self-tightening pad 2 and contacts.

Described self-tightening pad 2 and the contact surface of the object that is locked are pawl face, frosting or gold-plated emery.

Embodiment 2

Refer to Fig. 1-4, in this utility model embodiment, a kind of anti-loose self-tightening nut set, including self-tightening nut body 1 and self-tightening pad 2, it is provided with disjunctor lasso 3 on described self-tightening nut body 1, described self-tightening pad 2 is fastened on disjunctor lasso 3, the contact surface of described self-tightening nut body 1 and self-tightening pad 2 is the one or more helicoids seamlessly transitted, the helicoid of self-tightening nut body 1 is the most corresponding with the helical angle of the helicoid of self-tightening pad 2, and the helicoid of self-tightening nut body 1 coincide with the helicoid of self-tightening pad 2 and contacts.

Described self-tightening pad 2 and the contact surface of the object that is locked are pawl face, frosting or gold-plated emery face.

One end of disjunctor lasso 3 is one-body molded with self-tightening nut body 1 or self-tightening pad 2, the other end of disjunctor lasso 3 is connected with self-tightening pad 2 or self-tightening nut body 1, can be internal fastening type or exterior buckle type connection, after connection, self-tightening nut body 1 realizes integrated with self-tightening pad 2, and can be freely rotatable by disjunctor lasso 3, i.e. self-tightening nut body 1 and self-tightening packing ring 3 can be with axially free turn of pines of central shaft.

In self-tightening nut set, the inside diameter surface of self-tightening nut body 1 is flank, and the screw thread that this screw thread is matched with on bolt.

Self-tightening pad 2 is identical with corresponding for the helicoid B helical angle on self-tightening nut body 1, is set as " θ 1 ".

The helical angle that screw thread on bolt is corresponding is set as " θ 2 ".

M is self-tightening pad 2 and by the confficient of static friction between securing objects.

K is the confficient of static friction between self-tightening pad 2 helicoid and self-tightening nut body 1 helicoid.

When meeting condition [K+tan (θ 1)]/[1-Ktan (θ 1)]≤M, and during θ 1 ＞ θ 2, self-tightening effect is set up, the object now fastened will be by permanent locking, loosening or all shifting cannot occur in self-tightening nut body 1, unless self-tightening nut body 1 or self-tightening pad 2 body are destroyed.

From principle formula, when θ 1, θ 2 are constant, the effect from clamp force can be changed by changing the numerical value of M and K；Such as, when needing the value reducing K, helicoid can be processed by shot blasting, add light-plated synovial membrane, when needing the value increasing M, could be arranged to reverse pawl, frosting or gold-plated emery etc..

When the external diameter of self-tightening pad 2 is less than the external diameter of self-tightening nut body 1, just can realize anti-theft feature, i.e. do not have instrument can open self-tightening nut body 1, unless destroyed self-tightening nut body 1, because after self-tightening nut body 1 locking, only one of which method to be opened, it is exactly to turn on self-tightening pad 2 and self-tightening nut body 1 simultaneously, the thickness of self-tightening pad 2 own is the most relatively thin, if its external diameter is again less than the head outer diameter of self-tightening nut body 1, self-tightening pad 2 force the most more can not be opened by that.

This utility model uses autofrettage, self-tightening nut body 1 arranges a self-tightening structure, it is made after locking, to reach the effect of self-tightening, self-tightening nut body 1 is allowed displacement no longer to occur or loosens, this utility model can be widely applied to Machine Design, processing and manufacturing industry, and has revolutionary using value in railway, bridge and building trade；Global design is novel, practical, it is easy to promote the use of.

Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to various changes can be made on the premise of without departing from this patent objective.
