Disk, one end of circular base plate is equipped with can pass through with the matched hollow convex sphere curved surface of concave ball shape curved surface, the circular base plate
The openend of the embedded seal closure of extruding, realizes the tight fit between base and seal closure.
Preferably, the openend of the seal closure is equipped with flange, and flange is equipped with mounting hole.
Preferably, the quantity of the positioning card valve is 4；The quantity of the location hole is 4.
Preferably, the quantity of the bar-shaped trough is 6.
Preferably, the nut body and base select titanium alloy material.
Compared with prior art, the beneficial effects of the invention are as follows：(1) nut body passes through the uniform of circular conical surface internal whorl
Closing in and the separation of bar-shaped trough, make six conical surfaces become flexible member, are used cooperatively with bolt, reach reliable and stable self-locking effect
Fruit, realization repeatedly use function；(2) base is blocked the positioning card valve of nut body by the location hole of seal closure, close
Sealing cover discharges water rain-proof, realizes sealing nut performance, ensures bolt installation；(3) convex ball of the base to seal closure by related cooperation
Shape curved surface and concave ball shape curved surface, realizing the axis of the relatively spherical base of axis of nut body can tilt to all directions, ensure
Bolt centered assembling on airframe curved surface；(4) assembled by requirement, can repeatedly assemble and disassemble use, reducing makes
Use cost.

Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes.
Fig. 1 is referred to, the present invention includes nut body 1, seal closure 2 and base 3.
Fig. 2 is referred to, the inner wall of the nut body 1 is equipped with internal thread, and 1 one end margin of nut body is circumferentially uniform
Multiple positioning card valves 11 are provided with, the end face at the end is formed with hollow concave ball shape curved surface 12, and the other end uniformly closes up and forms circular cone
Face 13, equidistantly offers multiple bar-shaped troughs 14 on the circular conical surface 13 vertically.The nut body 1 and circular conical surface 13 it is interior
Wall is equipped with continuous internal thread.In the present embodiment, the quantity of the bar-shaped trough 14 is 6, and circular conical surface 13 is by even partition
Six cone angle faces, and six cone angle faces become flexible member.
Fig. 3 is referred to, the seal closure 2 is columnar structured for one end open, is circumferentially uniformly provided with barrel more
It is a to be sheathed on the nut body 1 with 11 matched location hole 21 of positioning card valve, the seal closure 2, and by that will determine
Position card valve 11, which is caught in location hole 21, to be pre-fixed.
Fig. 4 is referred to, the base 3 includes hollow circular base plate 31, and one end of circular base plate 31 is equipped with and concave ball shape
The matched hollow convex sphere curved surface 32 of curved surface 12, the circular base plate 31 can be by extruding opening for the embedded seal closure 2
Mouth end, realizes the tight fit between base 3 and seal closure 2.
In the present embodiment, the openend of the seal closure 2 is equipped with flange 22, and flange 22 is equipped with mounting hole 23, easy to pacify
Dress uses.
In the present embodiment, the quantity of the positioning card valve 11 is 4, and the quantity of corresponding location hole 21 is also 4.
In the present embodiment, the nut body 1 and base 3 select titanium alloy material, utilize the high spy of titanium alloy specific stiffness
Point, improves the density of load, alleviates nut weight.
Fig. 5 is referred to, assembling process of the invention is：Seal closure 2 is sheathed on nut body 1, and by that will position
Card valve 11 is caught in location hole 21 and is pre-fixed, and prevents from mutually rotating between seal closure 2 and nut body 1, but therebetween
For loose fit, nut body 1 has certain free degree in seal closure 2；Then by the convex sphere curved surface 32 and nut of base 3
The concave ball shape curved surface 12 of body 1 is aligned, and two curved surfaces is cooperated, while circular base plate 31 is extruded the embedded seal closure
2 openend, realizes the tight fit between base 3 and seal closure 2.
The present invention operation principle be：In use, bolt is screwed in the above-mentioned sealing nut assembled, due to hexagonal cone
The uniform closing in of face internal whorl, and the separation of bar-shaped trough, make six conical surfaces become flexible member, bolt is six during screw-in
Elastic deformation occurs for the conical surface, the thrust of bigger is produced to bolt, so as to reach reliable and stable self-locking effect；Base 3 with it is close
The convex sphere curved surface 32 and concave ball shape curved surface 12 that sealing cover 2 is coordinated by correlation, realize the relatively spherical base of axis of nut body 1
3 axis can ensure bolt centered assembling on airframe curved surface to all direction tilt rotations；Installing seal closure additional can realize
Waterproof rain-proof function.
Alternative in performance, the function traditional self-locking nut of the present invention, at the same solve traditional self-locking nut cannot
Waterproof, reuse number few (generally 15 times) etc. there are the problem of, Quick Release is held under the arm easy to install, it can be achieved that multiple weight soon
It is multiple to use (up to 250~1500 times), material and use cost is greatly saved.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of changes, modification, replace
And modification, the scope of the present invention is defined by the appended.
