The inclination angle of the cone tank of the top nut is 35 °；The inclination angle of the cone boss of the lower nut is
35°。
The centre of gyration line of the lower nut cone boss and the screw hole centre of gyration line of lower nut deviate 2 millimeters.
The present invention is a kind of anti-loosening bolt and nut lock solid structure；Including bolt and gasket；The bolt countersunk head ladder
Face is the cone boss to raise upward, and the centre of gyration line of the cone boss and the centre of gyration line of bolt screw rod deviate；It is described
Gasket bottom surface have an indent cone tank, the inner end of the cone tank is connected with the through-hole of gasket；The gasket set
It connects on the screw rod of bolt, cone tank and the cone boss on bolt screw rod for the gasket being socketed on bolt screw rod abut each other
And the cone tank of gasket is identical as the inclination angle of the cone boss of bolt.
The inclination angle of the cone tank of the gasket is 35 °；The inclination angle of the bolt screw rod cone boss is 35 °.
The centre of gyration line of the bolt screw rod cone boss and the cone tank centre of gyration line of gasket deviate 2 millimeters.
After adopting the above scheme, since the present invention includes bolt, top nut and lower nut；The bottom surface of top nut has one
The cone tank of indent, the cone boss that the top surface of lower nut has a bias and raises upward, the upper spiral shell being screwed on bolt
The eccentric cone boss of female cone tank and lower nut abuts each other, produces center line and misaligns, makes top nut and lower nut
Conical surface shield is mutually ratcheting, plays fastening effect, has the advantages that structure is simple, easy to use.
The present invention is further illustrated in the following with reference to the drawings and specific embodiments.

Specific embodiment
It as shown in figs 1 to 6, is a kind of one embodiment of anti-loosening bolt and nut lock solid structure of the present invention；Including spiral shell
Bolt 1, top nut 2 and lower nut 3.
The bottom surface of the top nut 2 has the cone tank 21 of an indent, inner end and the top nut 2 of the cone tank 21
Screw hole 22 is connected；The top surface of the lower nut 3 has a cone boss 31 to raise upward, the revolution of the cone boss 31
32 centre of gyration line of screw hole of center line and lower nut 3 deviates, and eccentric distance L is 2 millimeters；The top nut 2 and lower nut 3
It is successively screwed on bolt 1 from top to bottom, is screwed onto the cone tank 21 of the top nut 2 on bolt 1 and the cone boss of lower nut 3
31 abut each other and the cone tank 21 of top nut 2 is identical as the inclination angle a of 3 cone boss 31 of lower nut, are all 35 °.
The working principle of the present embodiment：
The top nut 2 of the present embodiment and lower nut 3 are matching used in pairs first, are divided into male shape nut and female shape nut, dress
Timing attention sequence, public shape nut（Lower nut 3）It is first filled in lower section, female shape nut（Top nut 2）It fills above.Public shape nut
（Lower nut 3）Using eccentric processing, female shape nut（Top nut 2）It is to be shaped to center line circle, when two male and female nuts
It when being screwed together, produces center line and misaligns, keep male and female nut conical surface shield mutually ratcheting, play fastening effect.
It is a kind of second embodiment of anti-loosening bolt and nut lock solid structure of the present invention as shown in Fig. 7-Figure 12；Including bolt
1 ' and gasket 2 '；1 ' countersunk head of bolt, the 11 ' cascaded surface is the cone boss 12 ' to raise upward, which returns
The centre of gyration line for turning center line and bolt screw rod 13 ' deviates, and eccentric distance L is 2 millimeters；The bottom surface of the gasket 2 ' has
One indent, uninfluenced cone tank 21 ', the inner end of the cone tank 21 ' is connected with the through-hole 22 ' of gasket 2 '；The pad
Piece 2 ' is socketed on the screw rod 13 ' of bolt 1, is socketed in the cone tank 21 ' and 1 ' spiral shell of bolt of the gasket 2 ' on 1 screw rod 13 ' of bolt
Cone boss 12 ' on bar 13 ' abuts each other and the inclination angle a of the cone boss 12 ' of the cone tank 21 ' of gasket 2 ' and bolt 1
It is identical, it is all 35 °.
It should be noted that bolt can use outer-hexagonal bolt 1 '（As shown in Figure 9）, hexagon socket head cap screw 1 " can also be used
（As shown in figure 13）
The working principle of the present embodiment：
The present embodiment is bolt 1 ' and gasket 2 ' is used cooperatively, and is made of spacer for bolt, and when assembly should be noted that sequence, gasket 2 '
Cone tank 21 ' is corresponding with 1 ' cone boss 12 ' of bolt, in the nut of insertion base aperture, firmly tightens, and rises anti-loosening
Effect.1 ' cone boss 12 ' of bolt uses contact surface taper, eccentric processing, and gasket 2 ' is also taper, not eccentric processing, when
When bolt 1 ' and the insertion base nut of gasket 2 ' are tightened, 1 ' center deviation of bolt produces 1 ' tooth of bolt and pedestal tooth pair
It should be engaged, play fastening, reach anti-loosening effect.
The above is only the preferred embodiment of the present invention, therefore cannot be limited the scope of implementation of the present invention with this, i.e., according to
Equivalent changes and modifications made by scope of the present invention patent and description should still belong to the model that the invention patent covers
In enclosing.
