Description
Technical field
This utility model belongs to MACHINERY JOINT field, more particularly, it relates to a kind of two process check bolt.
Background technology
Bolt is a great invention, is widely used, and its effect is to provide one kind for connection between various components or material
Combination, if in use nut loosening comes off, will lose interconnection function.Plain bolt cannot from structural principle analysis
Avoid loosening, its reason main cause is to lack axial force constraint between nut and screw rod, Jing Chang Fashengyin bolts pine in application
It is dynamic to cause mechanical breakdown and security incident, so, prevent nut loosening from being a difficult problem in bolt application.Spiral shell in prior art
The locking solution of bolt is a lot, and the higher application of some complex structure costs of manufacture is restricted, and some safeties are not high using can not
Lean on, the anti-loosen screw nut component of Hadlock（Patent 01135493）It is presently preferred solution, this " locking " solution party
Case opposed member is simple, is made up of two nuts, a nut axial direction convex, and plush copper is eccentric, another nut axial direction spill,
When two nuts pass through screw combinations, because concavo-convex combination is eccentric, radial force is produced when tightening and is interacted so that nut and spiral shell
Bar is tightly combined to be prevented from loosening, but it makes inconvenience, and without axial direction force constraint between two nuts, use time is long can also pine
Dynamic, its anti-loosing effect is not good, and this utility model provides a kind of check bolt of dependable performance, it is possible to resolve the technology in bolt application
A difficult problem.
Utility model content
The purpose of this utility model is to solve the problems, such as prior art, there is provided a kind of two process helicitic texture it is locking
Bolt.
To achieve these goals, the technical scheme that this utility model is taken is：This check bolt for being provided, including
The nut and anti-loose structure of bolt are tightened, described nut is provided with boss structure, including nut 1 is provided with convex microcephaly 12, boss 13
And nut 2 is provided with convex microcephaly 22, boss 23；Described anti-loose structure, including antirattle spring 3 and bridging nut 4, the bridging spiral shell
When mother 4 links together the convex microcephaly 12 of nut 1 and the convex microcephaly 22 of nut 2, bolt is generally in locking state.
To make above-mentioned technical proposal more detailed and concrete, this utility model also provides optimization technique further below
Scheme, to obtain satisfied practical function：
Described nut is provided with symmetrical boss structure, is axially arranged with screw, including nut 1 is provided with screw 11, convex microcephaly
12nd, boss 13 and the screw 21 of nut 2, convex microcephaly 22, boss 23, the convex microcephaly 12 of described nut 1 and the convex microcephaly 22 of nut 2 are provided with
Internal and external threads, and internal and external threads process is different, female thread specification is corresponding with the described screw thread units specification of screw rod 5, external screw thread rule
Lattice are corresponding with the bridging units specification of nut 4；Convex length L of microcephaly 12 of the nut 1, with antirattle spring reduction length and bridging nut
4 thickness L2Sum is adapted, and bridges the thickness L of nut 42More than convex length L of microcephaly 22 of nut 21。
This utility model compared with prior art, it is this with inside and outside silk two process screw nut combination bolt arrangement,
Due to the nut combined, not only produced when nut but also when working as screw rod, internal and external threads process difference, nut 1 or the rotation of nut 2
Axially-movable resistance so that nut 1 or nut 2 cannot be rotated, and realize screw retention, its advantage is：Simple structure, application spirit
Work, stable connection, antidetonation, temperature affect little, and construction and replacing bolt are convenient, it is not necessary to which firmly tightening reliably to use, tool
There is preferable application prospect.

Specific embodiment
Below against accompanying drawing, by the description to embodiment, specific embodiment of the present utility model is made further in detail
Thin explanation.
This two process check bolt of this utility model, as shown in Fig. 1 to 8, including nut 1, nut 2, antirattle spring 3,
Bridging nut 4, screw rod 5, the nut 1 is provided with screw 11, convex microcephaly 12, boss 13 and nut 2 and is provided with screw 21, convex microcephaly
22nd, boss 23, the convex microcephaly 12 of described nut 1 and the convex microcephaly 22 of nut 2 are provided with same size external screw thread, screw thread specification and bridging
Nut 3 matches, and nut 1 is connected with nut 2 by bridging nut 3, realizes screw retention function.
After the convex microcephaly 12 of nut 1 and the convex microcephaly 22 of nut 2 are bridged by bridging nut 4, component function is varied from, i.e. spiral shell
Mother 1 and nut 2 are both the screw rod that the nut of screw rod 5 bridges nut 4 again, due to nut 1 and the internal and external threads process of nut 2 difference
Axially-movable is constrained, nut 1 or nut 2 is rotated, nut 1 and nut 2 are bridged nut with the relative position of screw rod 5
4 lockings, realizing prevents bolt looseness.In connection, first the convex microcephaly 12 of nut 1 is screwed on screw rod 5, so towards reverse drive direction
Successively antirattle spring 3 and bridging nut 4 loaded into the convex microcephaly 12 of nut 1 afterwards, then by the convex microcephaly of nut 2 towards being screwed along stroke directions
On screw rod 5, after fitting with the convex microcephaly 22 of nut 2 to the convex microcephaly 12 of nut 1, bridging nut 4 is threaded to by the convex microcephaly 12 of nut 1
The convex microcephaly 22 of nut 2 forms bridging.
A kind of two process check bolt of this utility model, it is preferred that as shown in Fig. 2,3,6,7, the compression of antirattle spring 3 is long
Degree≤L1/3；The spread length of antirattle spring 3 is more than L1/2.
A kind of two process check bolt of this utility model, it is preferred that as shown in FIG. 4,5,6, 7, the convex microcephaly 22 of the nut 2
Length L1With the thickness L of the bridging nut 42Relation：L1=L21/2
When using, illustrate according to accompanying drawing 1 and accompanying drawing 8, first can combine nut 1 with antirattle spring 3, bridging nut 4, it is convex
Microcephaly 12 is screwed on screw rod 5 towards reverse drive direction, then the convex microcephaly 22 of nut 2 is treated into spiral shell towards being screwed on screw rod 5 along stroke directions
After female 1 convex microcephaly 12 fits with the convex microcephaly 22 of nut 2, bridging nut 4 is rotatably connected into the convex microcephaly 22 of nut 2 to boss 23
Realize screw retention function.
Shown in accompanying drawing 1, bridging nut 3 has realized that nut 1 is bridged with nut 2, and bolt has locking functions.
Shown in accompanying drawing 8, bridging nut 3 is not implemented nut 1 and bridges with nut 2, and bolt does not have locking functions.
This utility model is different using double thread process inside and outside nut, and double thread axial force is mutually restricted during rotation
Resistance is produced, nut axially-movable is prevented and cannot be rotated, realize screw retention.
Nut 1, nut 2, bridging nut 3, antirattle spring, the workpiece of screw rod 5 are not limited by material in this utility model, are made
Keep each junction function normal with middle, can be only achieved more preferable anti-loosing effect, if at bridging nut 4 and nut 1 and 2 liang of nut
Threaded connection loses spinfunction simultaneously, and bolt will lose anti-loosing effect.
Utility model works principle is exemplarily described above in conjunction with accompanying drawing, but this utility model is not received
It is limited to aforesaid way, pipe joint connecting structure can be expanded to, as long as using method of the present utility model design and technical scheme
The improvement of the various unsubstantialities for carrying out directly applies to other occasions, all falls within protection domain of the present utility model.
