The overall diameter of platform, and the second through hole to be connected with the first through hole is equipped with the first boss and second boss；
Packing ring, is provided with the third through-hole and fourth hole being mutually communicated in the packing ring, and the third through-hole with it is described
First boss gap coordinates, and the fourth hole coordinates with the second boss gap.
Alternatively, the connecting portion is arranged at the nut body end by cold heading technique.
Alternatively, the overall diameter of the packing ring is more than or equal to the overall diameter of the nut body.
Alternatively, height of height value of the packing ring in the axial direction than the connecting portion in the axial direction
Value is more than 1~1.5mm.
Alternatively, the nut is hex nut, and the packing ring is plain washer.
The beneficial effects of the utility model are：
Nut assembly provided by the utility model, the third through-hole in by packing ring and the first boss on nut connecting portion
Gap coordinates, and when the second boss gap on the fourth hole in packing ring and nut connecting portion is coordinated so that packing ring and spiral shell
Packing ring and connected piece so, when nut assembly is arranged on connected piece, can be caused with relative motion between mother
Between without relative motion, relatively rotated between packing ring and nut, be enable to nut support face of the prior art and
The frictional behavior of connected piece bearing surface is converted into nut assembly the frictional behavior between nut and packing ring, so as to solve
When existing conventional hexagonal nut, spring washer and plain washer combination bear transverse load between connector, easily
The problem of causing anti-loosing effect to fail；In addition, nut assembly includes packing ring, the installation process of packing ring is saved, improves peace
Fill efficiency.

Embodiment
Exemplary embodiment disclosed in the utility model is more fully described below with reference to accompanying drawings.Although shown in accompanying drawing
Exemplary embodiment disclosed in the utility model, it being understood, however, that may be realized in various forms the disclosure without should be by
Embodiments set forth here is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and energy
It is enough that the scope of the present disclosure is completely communicated to those skilled in the art.
Referring to Fig. 1 to Fig. 5, in one embodiment of the present utility model, nut assembly includes：
Nut 1, nut 1 include nut body 11 and are arranged at the connecting portion 12 of the end of nut body 11；Nut body 11
Interior to be provided with first through hole 111, connecting portion 12 includes being arranged at the first boss 121 of the end of nut body 11 and to be arranged at first convex
The second boss 122 of the end of platform 121；Wherein, the overall diameter of nut body 11 and the overall diameter of second boss 122 are all higher than first
The overall diameter of boss 121, and second to be connected with first through hole 111 is equipped with first boss 121 and second boss 122 and is led to
Hole 123；
Packing ring 2, packing ring 2 is interior to be provided with the third through-hole 21 and fourth hole 22 being mutually communicated, and third through-hole 21 and first
The gap of boss 121 coordinates, and fourth hole 22 coordinates with the gap of second boss 122.
So, because the overall diameter of nut body and the overall diameter of second boss are all higher than the overall diameter of first boss, because
An Access Division can be formed at this first boss, now the third through-hole of packing ring is socketed in first boss, and by packing ring
Fourth hole is socketed in second boss so that packing ring firmly can be socketed on connecting portion, so that packing ring will not be from
Come off on nut.In addition, third through-hole coordinates with first boss gap, fourth hole coordinates with second boss gap, so that
Obtaining can relatively rotate between packing ring and nut.
So, when nut assembly is arranged on connected piece, can cause between packing ring and connected piece without relative
Motion, is relatively rotated between packing ring and nut, that is, causes the relative rotation between packing ring and connected piece to be converted into packing ring and spiral shell
Relative rotation between mother, it is enable to the friction by nut support face of the prior art and connected piece bearing surface
Characteristic is converted into nut assembly the frictional behavior between nut and packing ring, in addition by being carried out to nut assembly at integral surface
Reason and lubricated, it is locking so as to reach can accurately control pretightning force so as to effectively control overall coefficient of friction
Effect, solve between existing conventional hexagonal nut, spring washer and plain washer combination are arranged on connector and bear transverse direction
During load, the problem of easily causing anti-loosing effect to fail.In addition, nut assembly includes packing ring, the installation of packing ring is saved
Journey, improve installation effectiveness.
In addition, further, connecting portion 12 can be arranged at the end of nut body 11 by cold heading technique.So, logical
, can be simultaneously using cold heading technique processing connecting portion, so that connecting portion and nut sheet when crossing cold headers upsetting nut body
Body can be integrally machined shaping, simplify processing and making process.
In addition, further, the overall diameter of packing ring 2 is more than or equal to the overall diameter of nut body 11.So, by nut
When component is arranged on connected piece, the surface of connected piece can protected abrasive meanwhile, it is capable to scattered spiral shell not by nut
Female pressure to connected piece, and increase the tautness between nut and connected piece.
In addition, further, height of the packing ring 2 in the axial direction is more than height of the connecting portion 12 in the axial direction
Degree.Specifically, height value of height value of the packing ring 2 in the axial direction than connecting portion 12 in the axial direction be more than 1~
1.5mm.Specifically, the height value of third through-hole is identical with the height value of first boss in connecting portion in packing ring, fourth hole
Height value is more than 1~1.5mm than the height value of second boss.So, the height value due to packing ring in the axial direction compares spiral shell
Height value of female connecting portion in the axial direction is more than 1~1.5mm, therefore can avoid end and the connected piece of nut
Between friction, so as to play a part of protection to connected piece.
In addition, further, nut 1 can be hex nut, packing ring 2 can be plain washer.So, it is possible to reduce nut
With the design cost of packing ring, and increase the use occasion of nut assembly.
Nut assembly in the present embodiment, nut use hex nut, and packing ring uses plain washer, reduces nut assembly
Design cost.In addition, the third through-hole in packing ring coordinates with first boss gap, fourth hole is matched somebody with somebody with second boss gap
Close so that can be relatively rotated between packing ring and nut.So, when nut assembly is arranged on connected piece, can make
Between packing ring and connected piece without relative motion, be relatively rotated between packing ring and nut, that is, cause packing ring and connected piece it
Between the relative rotation being converted between packing ring and nut, be enable to nut support of the prior art
The frictional behavior of face and connected piece bearing surface is converted into the frictional behavior between nut and packing ring in nut assembly, leads in addition
Cross and integral surface processing and lubricated are carried out to nut assembly, so as to effectively control overall coefficient of friction, with being capable of essence
Really control pretightning force, so as to reach locking effect, solves existing conventional hexagonal nut, spring washer and plain washer group
Close and be arranged between connector when bearing transverse load, the problem of easily causing anti-loosing effect to fail.In addition, wrapped in nut assembly
Packing ring is included, the installation process of packing ring is saved, improves installation effectiveness.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
The scope of protection of the utility model is also should be regarded as with retouching.
