The shape for determining structure is "T"-shaped, the groove of the periphery setting of flange nut flange and the T shape fixed structure of internal tooth washer setting
Corresponding, the groove cross section of flange nut periphery setting is identical as the cross section of T shape built-in structure that internal tooth washer is arranged,
The groove of T shape fixed structure and flange nut flange circle the circumferential surface setting of internal tooth washer cooperates, flange nut and internal tooth pad
Circle is by being stamped and formed out punching press sub-assembly, and T shape 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 structure replaces 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 structure 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 cooperated by itself rotation 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.
The utility model has the advantages that 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 embodiment
Below in conjunction with Detailed description of the invention and specific embodiment, the present invention is described in further detail: a kind of anti-loosening method
Blue nut, it is characterised in that be made of flange nut, internal tooth washer 4, the flange 2 of flange nut and the faced washer of internal tooth washer
4 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 shape
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 shape fixed structure 5 of setting is corresponding, and 3 cross section of groove of flange nut periphery setting and the T shape of internal tooth washer setting are solid
The cross section of binding structure 5 is identical, 3 phase of groove that the T shape fixed structure 5 of internal tooth washer is arranged with 2 periphery of flange nut flange
By being stamped and formed out punching press sub-assembly, T shape fixed structure 5 is vertical when combining completion for mutually cooperation, flange nut and internal tooth washer
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 shape 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 knot 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 pressure
Will not also the screw thread of screw rod to bolt itself cause to damage.Internal tooth washer can also be using materials such as plastics, rubber, to increase
Add the coefficient of friction 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 revolved
Tightly, until a kind of anti-loosening flange nut is close to by fastenings.Continue tightening nut at this time, then the contact surface of part can be continuous
The internal tooth 6 that internal tooth washer tilts is squeezed, so that the internal tooth 6 of internal tooth washer is intended to parallel with faced washer 4 or puts down in same
Face.The spiral shell of nut body 1 is continuously subject to 4 approximately the same plane of faced washer, 6 top of internal tooth as internal tooth 6 is extruded to simultaneously
The center in hole.The screw diameter of bolt is constant at this time, so internal tooth 6 is contacted with screw flight, and is squeezed and deformed, internal tooth washer
Internal tooth 6 radial be clamped on bolt or in thread groove.Friction pressure is passively provided relative to conventional nylon stop nut
Phenomenon, a kind of anti-loosening flange nut constantly being tightened with nut body, the internal tooth 6 of internal tooth washer constantly by axial compressive force and
Radial pressure squeezes jointly, ultimately forms bigger extruding force and closer is engaged.At this time internal tooth washer and screw rod,
Very big contact pressure is formd between screw thread, according to frictional force calculation formula it is found that pressure is bigger, frictional force is bigger, so
A kind of locking kinetic force of friction of anti-loosening flange nut of the present invention is far longer than plain nut, even greater than nylon stop nut,
Good anti-loosening effect can be played.To finally the locking between bolt and nut be realized, so that will not be occurred by fastenings
Any loosening ensure that the reliability and safety of equipment.A kind of anti-loosening flange nut structure is simple, it is easy to process, use
It is convenient, never becoming loose truly may be implemented.
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.
