Abstract
The utility model provides a flange nut, include: a terminal surface is the nut body of flange face, be equipped with central threaded hole along the axis direction on the nut body, central threaded hole extends to on the flange face, be provided with on the flange face with the endocentric protruding structure of central threaded hole. Anti -loosening performance has been guaranteed more to clamp force and uniformity that this structure produced in the time of can effectively improving the assembly moment of torsion, and technical content is high.
Description
Technical field
This utility model relates to a kind of automobile component, particularly relates to a kind of flange nut.
Background technology
Now, the end face band tooth stop nut on market uses increase to become radial convex centered by screwed hole
Play feature, prevent the rotation of nut rotational direction with this.The shortcoming of this kind of structure is that adding nut breaks
Frictional force between face and connected piece and discreteness thereof.The bolt causing such nut to produce in use is pre-
Clamp force is little and discrete, is less useful for the locking of joint sometimes.
Utility model content
In order to overcome the problems referred to above, this utility model provides a kind of flange nut, original radial for solving
The problem that contact surface frictional force that bulge-structure feature causes is big and unstable.
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of flange nut, including:
End face is the nut body of flange face, and described nut body is provided with screwed hole of centre in the axial direction,
Described screwed hole of centre extends on described flange face, described flange face is provided with and described screwed hole of centre
Concentric bulge-structure.
Alternatively, described bulge-structure is multiple, and described bulge-structure includes and described screwed hole of centre phase
The first adjacent bulge-structure, wherein, is respectively provided with the first spacing between adjacent two described bulge-structures, described
Between edge and described first bulge-structure of screwed hole of centre, there is the second spacing, wherein said first spacing
Equal to described second spacing.
Alternatively, the cross section of described bulge-structure is U-shaped.
Alternatively, the cross section of described bulge-structure is rectangle, triangle or trapezoidal.
Alternatively, the quantity of described bulge-structure is two.
Alternatively, being perpendicular to the centerline direction of described screwed hole of centre, the cross section of described nut body is six
Dihedral.
The beneficial effects of the utility model are:
Above-mentioned flange nut structure, being provided with on end face of flange with screwed hole is concentrically ringed protruding features,
This bulge-structure can improve the coefficient of friction concordance between nut and connected piece, and make that bolt produces is pre-
Clamp force dispersion is little, reaches the purpose that pretightning force is controlled.Further, since concentric circular feature is permissible on microcosmic
It is absorbed in connected piece surface, thus promotes and prevent from occurring between nut and connected piece the ability of relative translation,
Thus preventing nut from loosing due to relative motion from bolt, this structure can be effectively improved assembling moment of torsion
Time produce clamping force and concordance, more ensure that anti-loosening property, with high content of technology.
Accompanying drawing explanation
Fig. 1 represents the overall schematic of flange nut in this utility model；
Fig. 2 represents the generalized section of flange nut in this utility model.

1-flange face, 2-nut body, 3-screwed hole of centre, 4-bulge-structure.
Detailed description of the invention
It is more fully described the exemplary embodiment of the disclosure below with reference to accompanying drawings.Although accompanying drawing shows
The exemplary embodiment of the disclosure, it being understood, however, that may be realized in various forms the disclosure and should be by
Embodiments set forth here is limited.On the contrary, it is provided that these embodiments are able to be best understood from this
Open, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Shown in Fig. 1, Fig. 2, the utility model discloses a kind of flange nut, this flange nut includes:
End face is the nut body 2 of flange face 1, and this nut body 2 is provided with screwed hole of centre in the axial direction
3, this screwed hole of centre 3 extends to, on this flange face 1, this flange face 1 be provided with and screwed hole of centre
3 concentric bulge-structures 4.
Flange nut in this utility model, being provided with on end face of flange with screwed hole is concentrically ringed projection
Feature, this bulge-structure 4 can improve the coefficient of friction concordance between nut and connected piece, make bolt
The pretightning force dispersion produced is little, reaches the purpose that pretightning force is controlled.Further, since concentric circular feature is micro-
Connected piece surface can be absorbed on Guaning, thus promote and prevent from occurring between nut and connected piece relative translation
Ability, thus prevent nut from loosing due to relative motion from bolt, this structure can be effectively improved
The clamping force produced during assembling moment of torsion and concordance thereof, more ensure that anti-loosening property, with high content of technology.
Specifically, this bulge-structure 4 is multiple, and described bulge-structure 4 includes and described screwed hole of centre
3 the first adjacent bulge-structures, wherein, are respectively provided with the first spacing between adjacent two described bulge-structures 4,
There is between edge and described first bulge-structure of described screwed hole of centre 3 second spacing, wherein said
One spacing is equal to described second spacing.
Preferably, the cross section of described bulge-structure 4 is U-shaped.Preferably, described bulge-structure 4
Cross section is rectangle, triangle or trapezoidal.The cross section of this bulge-structure 4 can be rectangle, triangle or
Trapezoidal, it is also possible to be " u "-shaped, concrete shape can determine according to process conditions and real needs.
Wherein, the quantity of this bulge-structure 4 is preferably two, the locking feature of end face of flange of this flange nut
Mainly form by cold headers upsetting system or by machining cutting, form two circle concentric circulars protruding, so that meet should
The anti-loosening property of product.
Preferably, it is perpendicular to the centerline direction of described screwed hole of centre 3, the cross section of described nut body 2
It is hexagonal flange stop nut for hexagon, i.e. this flange nut.
Above-described is preferred implementation of the present utility model, it should be pointed out that general for the art
For logical personnel, some improvement and profit can also be made under without departing from principle premise described in the utility model
Decorations, these improvements and modifications are also in protection domain of the present utility model.
