Concave inner is equipped with concave surface flank, is provided through bolt hole at left and right sides of the concave surface, the sub- nut lower end with,
Female nut upper end is equipped with joint face.
As further program of the utility model, the convex surface is agreed with concave surface size, and concave surface flank and convex surface
The occlusion of flank size.
As further program of the utility model, the convex surface flank, concave surface flank diameter be all larger than interior spiral shell
The diameter in line face.
As further program of the utility model, the bolt hole is through the entire concave side edge of setting.
As further program of the utility model, the joint face is rubber joint face, and joint face and inner threaded surface
Between fit closely.
Compared with prior art, the beneficial effects of the utility model are as follows:
Agreed with by being equipped with convex surface with concave surface size, and concave surface flank is engaged with convex surface flank size, convex surface screw thread
Face, concave surface flank diameter be all larger than the diameter of inner threaded surface, concave surface flank is mutually twisted with convex surface flank, so that recessed
Convex surface is carried out nesting by face, and then sub- nut is fixed, and compared with the prior device, this is designed so that sub- nut and female nut
Between being engaged by concave surface flank and convex surface flank, carry out mutual stress containing, avoid any one nut by
It is loosened when vibration, solves the problems, such as that single nut easily loosens；
By being equipped with bolt hole through entire concave side edge is arranged, it is embedded into bolt hole using bolt, two can be increased
Frictional force between a nut, locks nut, can avoid two nuts and separates because of vibration, solves existing spiral shell
The problem of defective tightness is connected between mother；
It is rubber joint face by being equipped with joint face, and is fitted closely between joint face and inner threaded surface, rubber joint face
Gap between sub- nut, female nut and bolt is sealed, prevents water droplet etc. from entering the connection of inner threaded surface and bolt
Place and cause screw thread to get rusty, increase the use scope of nut, solve the problems, such as that existing nut seal is imperfect.
In conclusion whole device stable structure, the holdback force between two nuts is stronger, and frictional force is bigger, is not easy to send out
Raw to loosen, better tightness has very high promotional value.
