By such scheme, described spacing a is 0.1~3 ㎜.
By such scheme, the outer rim of the side end face of the first nut one is provided with block, the block outermost end and described the
The distance of the central axis of one nut is more than or equal to the radius of the minimum circumscribed circle of the first nut.
By such scheme, the block is the lug that is extended centrally out along the first nut side or along the first spiral shell
A female side end face periphery block structure to be formed to stretching out.
By such scheme, the block is marked provided with letter or number or word or breach or hole or line ball or impression
Know.
The beneficial effects of the utility model are：1st, by setting the taper hole or tapered flanges of beat so that the first nut and
Second nut produces a moment of torsion when configuration is tightened, and nut produces a torsion snap-in force, reached more with respect to screw rod beat
Good anti-loosing effect；2nd, on the basis of beat, by setting translation spacing to make to produce a radial direction wedge between nut and screw rod
With joint efforts, make between nut and screw rod screw thread engagement and be engaged tighter, dramatically increase the frictional force between nut assembly and bolt, from
And prevent nut from releasing；3rd, the utility model also has simple in construction, the characteristics of setting is reasonable, and easy to use.

Embodiment
To more fully understand the utility model, the utility model is made further to retouch with reference to the accompanying drawings and examples
State.
As Figure 1-3, a kind of anti-loosen screw nut component, including the first nut 1 and the second nut 2, the side of the first nut one
Middle face is provided with the taper hole 3 of major part outwardly, provided with the tapered flanges 4 that major part is inside in the middle part of the side end face of the second nut one, taper hole with
Tapered flanges phase configuration, the taper hole axis of the first nut is convex with respect to the taper of one angle k of screw axis beat or the second nut
Edge axis is with respect to one angle k of screw axis beat, and deflection angle k is 1~8 °.
Meanwhile, the taper hole axis of the first nut with respect to one angle of screw axis beat and simultaneously one spacing of offset translation
A, the tapered flanges axis and screw axis of the second nut coincide；Or second nut tapered flanges axis with respect to screw axis
One angle of beat and simultaneously one spacing a of translation, taper hole axis and the screw axis of the first nut coincide, and spacing a is 0.1
~3 ㎜.
The outer rim of the side end face of first nut one is provided with block 5, block outermost end and the distance of the central axis of the first nut
More than or equal to the radius of the minimum circumscribed circle of the first nut, when tightening the first nut using tightening tool, tightening tool will
It is resisted against on block so that tightening tool will not slide to the second nut and be engaged with the second nut, so will easily tighten
First nut.
Block is the lug or the side end face periphery along the first nut extended centrally out along the side of the first nut
The block structure to be formed to stretching out.Block is marked provided with letter or number or word or breach or hole or line ball or impression
Know, the anglec of rotation of nut can conveniently be seen by observing by the naked eye, so, we can also be while tighten nut, a frontier inspection
Look into added torque.
During using the anti-loosen screw nut component, first the second nut is tightened on bolt 6 with a predetermined torque, then, will
First nut is tightened on bolt with another predetermined torque, and the torque of nut can be set according to actual conditions, is being twisted
During tight first nut, the block on the first nut will withstand impact wrench, such impact wrench when tightening the first nut just not
It can move down and be meshed with the second nut, and be rotated together with the first nut.
When tightening the first nut, the angle of nut rotation can be judged by observing block, so as to easily sentence
Whether fixed first nut is tightened with predetermined torque.Detailed operational circumstances are as follows：The second nut is touched soon in the first nut
When, we are rotating slowly impact wrench, when the first nut rigid connection contacts the second nut, the flange insertion groove being obliquely installed
In or the groove that is obliquely installed of flange insertion in when, we, which can feel, needs to increase by obvious torque (first nut
Not in contact with to the torque that a very little is only needed to before the second nut), at this moment, we only need to the block that detects by an unaided eye and record
Initial position, then with impact wrench by the angle of the first nut rotation a to fixed value (corresponding to predetermined torque),
Due to the close occlusion of the first nut and the second nut so that the first nut and the second nut produce a torsion when configuration is tightened
Square, nut produces a torsion snap-in force with respect to screw rod beat, reaches more preferable anti-loosing effect, and translation spacing can make nut
A radial direction wedging power is produced between screw rod, makes between nut and screw rod screw thread engagement and is engaged tighter, dramatically increase nut group
Frictional force between part and bolt, so as to prevent nut from releasing.
