Slip teeth line；The flange circle circumferential surface of flange nut is provided with groove, and internal tooth washer outer circle side is provided with T shape fixed structures, and T-type is solid
The shape for determining structure is "T"-shaped, the T shape fixed structures of the groove and the setting of internal tooth washer of the periphery setting of flange nut flange
Corresponding, the groove cross section of flange nut periphery setting is identical as the cross section for the T shape built-in structures that internal tooth washer is arranged,
The T shapes fixed structure of internal tooth washer and the groove of flange nut flange circle circumferential surface setting cooperate, flange nut and internal tooth pad
Circle is by being stamped and formed out punching press sub-assembly, and T shapes fixed structure is when combining completion perpendicular to the plane of faced washer；Flange nut
Flange periphery setting groove could alternatively be flange nut Flange Plane setting through-hole, while internal tooth washer setting
T shape fixed structures replace with the positioning cylinder of internal tooth washer side plane setting, and positioning cylinder passes through flange nut flange when combination
The through-hole of face setting, it is affixed by punching press；The groove of the periphery setting of flange nut flange could alternatively be C-shaped ring, C-shaped ring
Cross section be " C " shape, while removing the T shape fixed structures of internal tooth washer, C-shaped is fixed in the faced washer part of internal tooth washer
In ring.
A kind of anti-loosening flange nut is coordinated by the rotation of itself by the contact surface of fastenings, by internal tooth washer
Internal tooth compressive deformation is stuck in bolt thread slot, increases the screw rod and nut closeness of contact, mutual extruding force of bolt, from
And the frictional force of nut and bolt is improved, play anti-loosening effect.
Advantageous effect：The present invention can efficiently solve railway, train, automobile and Other Engineering mechanized equipment because of equipment
Constantly vibration causes the common bolt device of fixed equipment to occur to loosen and the equipment breakdown of initiation, thus is conducive to improve
The safety of vibratory equipment in use.It is locking instead of tradition such as various conventional nuts, nylon stop nut, live dispensings
Dynamic method, while the piece surface being fastenedly connected will not be damaged.

Specific implementation mode
Below in conjunction with description of the drawings, the present invention is described in further detail with specific implementation mode：A kind of anti-loosening method
Blue nut, it is characterised in that be made of flange nut, internal tooth washer 4, the flange of flange nut and the faced washer 4 of internal tooth washer
It is affixed；Internal tooth washer is made of faced washer 4 and internal tooth 6, and internal tooth 6 and the inner circle of faced washer 4 are affixed, internal tooth 6 and planar pad
The side plane of circle 4 is a certain included angle, and angulation is acute angle；The faced washer 4 of internal tooth washer is flat far from flange nut side
Face is provided with anti-skidding groove；2 periphery of the flange setting fluted 3 of flange nut, it is solid that internal tooth washer outer circle side is provided with T shapes
Determine structure 5, the shape of T-type fixed structure 5 is "T"-shaped, the groove 3 and internal tooth washer of the periphery setting of flange nut flange 2
The T shapes fixed structure 5 of setting is corresponding, and 3 cross section of groove of flange nut periphery setting and the T shapes of internal tooth washer setting are solid
The cross section of binding structure 5 is identical, 3 phase of groove that the T shapes fixed structure 5 of internal tooth washer is arranged with 2 periphery of flange nut flange
Mutually cooperation, for flange nut with internal tooth washer by being stamped and formed out punching press sub-assembly, T shapes fixed structure 5 is vertical when combining completion
In the plane of faced washer 4；The groove 3 of the periphery setting of flange nut flange 2 could alternatively be flange nut Flange Plane
The through-hole of setting, while the T shapes fixed structure 5 of internal tooth washer setting replaces with the positioning cylinder of internal tooth washer side plane setting,
Positioning cylinder passes through the through-hole of 2 face of flange nut flange setting when combination, affixed by punching press；The circumference of flange nut flange 2
The groove 3 of face setting could alternatively be C-shaped ring, and the cross section of C-shaped ring is " C " shape, while removing the T shape fixed knots of internal tooth washer
4 part of faced washer of structure 5, internal tooth washer is fixed in C-shaped ring.The material of internal tooth washer is less than bolt joined together using hardness
Metal material, for example, the materials such as copper internal tooth washer, aluminum internal tooth washer, it is ensured that while higher contact
Also the screw thread of the screw rod of bolt itself will not be caused to damage.Internal tooth washer can also use the materials such as plastics, rubber, to increase
Add the friction coefficient of internal tooth after squeezing.
The method of operation：
When using the present invention, screw rod is inserted in a kind of side that anti-loosening flange nut is provided with internal tooth washer and is constantly screwed, directly
To a kind of anti-loosening flange nut close to by fastenings.Continue tightening nut at this time, then the contact surface of part can be squeezed constantly
The internal tooth 6 that internal tooth washer tilts so that the internal tooth 6 of internal tooth washer is intended to parallel with faced washer 4 or is in same plane.Together
When be continuously subject in the screw hole of nut body 1 with 4 approximately the same plane of faced washer, 6 top of internal tooth as internal tooth 6 is extruded to
The heart.The screw diameter of bolt is constant at this time, so internal tooth 6 is contacted with screw flight, and crimp, the internal tooth of internal tooth washer
6 radial directions are clamped on bolt or in thread groove.The phenomenon that passive relative to conventional nylon stop nut offer friction pressure, one
The anti-loosening flange nut of kind constantly being tightened with nut body, and the internal tooth 6 of internal tooth washer is constantly by axial compressive force and radial pressure
Power squeezes jointly, ultimately forms the extruding force of bigger and closer is engaged.At this time internal tooth washer and screw rod, screw thread it
Between form prodigious contact, according to frictional force calculation formula it is found that pressure is bigger, frictional force is bigger, so of the invention
A kind of locking kinetic force of friction of anti-loosening flange nut is far longer than plain nut, even greater than nylon stop nut, Ke Yiqi
To good anti-loosening effect.It will finally realize the locking between bolt and nut so that any pine will not be occurred by fastenings
It is dynamic, it ensure that reliability and the safety of equipment.A kind of anti-loosening flange nut is simple in structure, easy to process, easy to use, can
To realize never becoming loose truly.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
