Description
Technical field
A kind of friction fastener is the utility model is related to, belongs to fastener areas.
Background technology
Bolt is a kind of common fastener, and it is by bolt head and screw rod（With externally threaded cylinder）Two parts group
Into, need to coordinate with nut, for be fastenedly connected two carry through hole parts.This type of attachment claims bolt connection.As spiral shell
Mother screws off from bolt, can separate the two parts again, therefore bolt connection is to belong to be detachably connected.At present, in order to anti-
Only bolt looseness, anti-slop serrations are set in bolt head lower surface, is contacted with piece surface by anti-slop serrations, had to a certain extent
Locking effect.But having relative slip during screwing bolts, between anti-slop serrations and piece surface, anti-slop serrations can be by
Gradually it is smoothed, anti-loosing effect weakens significantly.In order at utmost strengthen the anti-loosing effect of bolt, current anti-skidding toothing
Need to redesign.
The content of the invention
Technical problem to be solved in the utility model is：A kind of friction fastener is provided, it is solved at present
Bolt head anti-slop serrations are easily worn when screwing, the problem of causing anti-loosing effect to weaken significantly.
Technical problem to be solved in the utility model takes following technical scheme to realize：
A kind of friction fastener, it include bolt, Upper gasket, lower gasket, spring, the bolt by top bolt
Head, the threaded portion of the slide bar portion at middle part and bottom are formed, and the cross sectional shape in slide bar portion is polygon, the width of slide bar portion the widest part
More than threaded portion diameter, the cross sectional shape size identical polygonal openings with slide bar portion are offered in the middle part of the Upper gasket, on
Pad lower surface is provided with an anti-inverted teeth of circle, be provided with the middle part of the lower gasket with threaded portion diameter identical bolt hole, on lower gasket
Surface is provided with a circle anti-inverted teeth corresponding with Upper gasket, and lower gasket lower surface is provided with anti-slop serrations, spring, Upper gasket are sequentially sleeved in
The slide bar portion of bolt, lower gasket are enclosed on the threaded portion of bolt, anti-between Upper gasket, lower gasket under the elastic force effect of spring
Inverted teeth tightly engages, and prevents from producing backwards rotation between bolt and lower gasket, the contact surface between the slide bar portion and lower gasket
Scribble lubricating oil.
As preferred embodiment, the cross sectional shape in the slide bar portion is square or regular hexagon.
As preferred embodiment, plectrum is provided with the outside of the Upper gasket.
The beneficial effects of the utility model are：Upper gasket is up dialled by plectrum, the anti-inverted teeth of Upper gasket and lower gasket
Separate, now screwing bolts, because the contact surface between slide bar portion and lower gasket scribbles lubricating oil, lower gasket is anti-skidding when screwing
Tooth, almost without relative motion, can farthest keep skidproof effect, after tightening, plectrum is put down, upper pad with piece surface
Piece is engaged with lower gasket by anti-inverted teeth, prevents bolt from being loosened after reversing.

Fig. 2 is the utility model Upper gasket, the structural representation of lower gasket engagement；
Fig. 3 is the structural representation of the utility model Upper gasket；
Fig. 4 is the structural representation of the utility model lower gasket.
In figure：Upper gasket 1, lower gasket 2, spring 3, bolt head 4, slide bar portion 5, threaded portion 6, polygonal openings 7, anti-inverted teeth
8, bolt hole 9, anti-slop serrations 10, plectrum 11.
Embodiment
In order to be easy to understand to technological means of the present utility model, creation characteristic, reached purpose and effect, tie below
Conjunction is specifically illustrating, and the utility model is expanded on further.
As Figure 1-Figure 4, a kind of friction fastener, it includes bolt, Upper gasket 1, lower gasket 2, spring 3, spiral shell
Bolt is made up of the threaded portion 6 of the bolt head 4 at top, the slide bar portion 5 at middle part and bottom, and the cross sectional shape in slide bar portion 5 is polygon,
The width of the widest part of slide bar portion 5 is more than the diameter of threaded portion 6, and the middle part of Upper gasket 1 offers the cross sectional shape size phase with slide bar portion 5
Same polygonal openings 7, the lower surface of Upper gasket 1 are provided with an anti-inverted teeth 8 of circle, and the middle part of lower gasket 2 is provided with identical with the diameter of threaded portion 6
Bolt hole 9, the upper surface of lower gasket 2 is provided with corresponding with a Upper gasket 1 anti-inverted teeth 8 of circle, and the lower surface of lower gasket 2 is provided with anti-slop serrations
10, spring 3, Upper gasket 1 are sequentially sleeved in the slide bar portion 5 of bolt, lower gasket 2 is enclosed on the threaded portion 6 of bolt, in the bullet of spring 3
Under power effect, the anti-inverted teeth 8 between Upper gasket 1, lower gasket 2 tightly engages, and prevents from producing reverse turn between bolt and lower gasket 2
Dynamic, the contact surface between slide bar portion 5 and lower gasket 2 scribbles lubricating oil.
The cross sectional shape in slide bar portion 5 is square or regular hexagon.
The outside of Upper gasket 1 is provided with plectrum 11.
Before twisting bolt, first passing through plectrum 11 and up dial Upper gasket 1, Upper gasket 1 separates with the anti-inverted teeth 8 of lower gasket 2,
Now screwing bolts, Upper gasket 1 rotate together with bolt, because the contact surface between slide bar portion 5 and lower gasket 2 scribbles lubrication
Oil, the anti-slop serrations 10 of lower gasket 2 and piece surface will not wear anti-slop serrations 10 almost without relative motion when screwing, can be maximum
Skidproof effect is kept to degree, after tightening, plectrum 11 is put down, Upper gasket 1 is engaged with lower gasket 2 by anti-inverted teeth 8, prevents spiral shell
Bolt loosens after reversing.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, do not depart from the utility model spirit and
On the premise of scope, the utility model also has various changes and modifications, and these changes and improvements both fall within the utility model will
In the range of asking protection.The utility model requires protection scope is by appended claims and its equivalent thereof.
