Screw thread.The bolt head stress surface has multiple incised grooves to be circularly and evenly distributed counterclockwise.
A kind of antivibration check bolt nut fastener further includes nut, the nut include nut stress surface, nut it is non-by
Power face, the hollow connecting portion of nut.The hollow connecting portion inner wall of nut is equipped with screw thread；The nut stress surface has multiple sawtooth
Connected in star is circularly and evenly distributed counterclockwise；The nut non-stress face is to have chamfer plane.
A kind of antivibration check bolt nut fastener further includes locking pad, and the locking pad is hollow air ring, two sides
It is stress surface, wherein there is multiple incised grooves in the direction of the clock in circle on the face being in contact with the bolt or nut
Week is uniformly distributed；Another side has the anti-skid chequer being circularly and evenly distributed.
As restriction, the locking pad must be applied in combination with bolt described in the utility model or nut, the locking pad
Incised groove it is equal with the number of the bolt or the incised groove of nut and using when incised groove between mutually sting
Close.
Above-mentioned technical proposal, the technological progress of acquirement are：The utility model fastener fastening means is both that tension is locking
It is, simple in structure, convenient disassembly locking from clamp force again, anti-loosening property is stablized.

Embodiment is modified.Therefore, attached drawing and description are regarded as illustrative in nature, rather than for limiting the protection of claim
Scope.
Embodiment 1
A kind of antivibration check bolt nut fastener, including bolt 1, the bolt 1 include bolt head 1-2, bolt head by
Power face 1-3, bolt head non-stress face 1-4, screw rod 1-5, right-handed thread 1-6.The bolt head non-stress face 1-4 puts down for chamfering
Face；Right-handed thread is carried on the screw rod 1-5.The bolt head stress surface 1-3 has multiple bolt incised groove 1-7 by the inverse time
Pin direction is circularly and evenly distributed.Incised groove on 3 liang of contact surfaces of bolt 1 and locking pad is mutually engaged, and then will be fastened
Thing fastens (such as Fig. 6).
Embodiment 2
A kind of antivibration check bolt nut fastener, further includes nut 2, and the nut 2 includes nut stress surface 2-2, spiral shell
Female non-stress face 2-3, hollow connecting portion 2-4.The hollow connecting portion 2-4 inner walls of nut 2 are equipped with screw thread；The nut stress
Face 2-2 has multiple nut incised groove 2-5 to be circularly and evenly distributed counterclockwise；The nut non-stress face 2-3 is
There is chamfer plane.Incised groove on 3 liang of contact surfaces of nut 2 and locking pad is mutually engaged, so by nut 2 and plain bolt it
Between fastened by fastener (such as Fig. 5).
Embodiment 3
A kind of antivibration check bolt nut fastener further includes locking pad 3, and the locking pad 3 is hollow air ring, and two
