The invention relates to the application field of connectors and fasteners, in particular to a self-adjusting detachable high-locking nut assembly. The self-adjusting detachable high-locking nut assembly comprises a concave spherical washer and a locking part, wherein the locking part comprises a working part and a process part which are of an integrated structure; the working part is of a three-section integrated structure from front to back, a front section is of a convex spherical structure, a middle section is an arc-shaped shoulder, and a rear section is of an outer-hexagonal structure; an inner threaded hole is formed in the working part; a flaring is formed in the front end of the inner threaded hole; and the front end of the concave spherical washer is a flat end surface, and the rear end of the concave spherical washer is a concave spherical structure matched with the convex spherical structure. The self-adjusting detachable high-locking nut assembly has the beneficial effects that 1, the front section is of the convex spherical structure and is matched with the concave spherical washer, and under the condition that a certain inclination angle exists in an interlayer, firm connection can still be realized in an exactly matched mode; 2, the middle section is the arc-shaped shoulder, a torque wrench does not collide with the surface of an assembly plate when a nut is disassembled, and therefore the protection effect can be achieved; and 3, the rear section is of the outer-hexagonal structure so that repeated use after installation can be realized.
Description
Technical field
The present invention relates to connector fastener application field, more particularly to a kind of detachable Closely locking nut component of self-adjusting.
Background technology
General nut can be released due to reasons such as vibrations in use, for the pine for solving to occur in nut use
De- problem, people have invented self-locking nut.The operation principle of self-locking nut is by increasing the frictional force of screw connection point with reality
Existing antivibration locking functions.The type of self-locking nut is more, and it mainly has embedded nylon ring, special thread tooth bottom and adds metal locking
The types such as device.For aerospace field, in the attachment structure of aircraft, required to meet its flight, it usually needs
Using lightweight, and fatigue strength connector high.In present aerospace field, tied using Closely locking nut
Structure is connected, on the one hand, although Closely locking nut can meet the self-locking requirement of connection, its structure is more complicated, generally all by technique
Part and the supporting connection of working portion are used, and existing working portion is cylindrical structure, smooth outer surface, so can only after installing
Dismantled by means of destruction, can not be reused after dismounting, this is allowed for its use and more bothered, and is easily caused big
The waste of material resources is measured, is unfavorable for cost-effective.
On the other hand, it is planar end surface in the front end of working portion that existing Closely locking nut is general, if install interlayer had necessarily
Angle of inclination, then conventional high locked bolts nut screw connection connection cannot realize firm connection in this case.
The content of the invention
For the deficiency in structure in the prior art, the present invention provides a kind of good self-locking property, simple structure, user
Just, light weight, can reuse and can have on the interlayer at certain angle of inclination consolidate connection self-adjusting it is detachably high
Split nut component.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of detachable Closely locking nut component of self-adjusting, its
It is characterised by, including concave spherical surface packing ring and locking member, the locking member is included in the working portion and process portion of integrative-structure；
The working portion from front to back be three sections of integrative-structures, leading portion be convex spherical structure, stage casing be curved shoulder, after
Section is outer-hexagonal structure, and the working portion is provided with internal thread hole, and the front end of the internal thread hole is provided with enlarging；
The concave spherical surface gasket leading end is planar end surface, and rear end is the concave spherical surface structure being adapted with shown convex spherical structure.
The beneficial effects of the invention are as follows：1st, front end is convex spherical structure, coordinates concave spherical surface packing ring, has certain inclination in interlayer
In the case of angle, the firm connection that can also fit together perfectly.
2nd, stage casing is curved shoulder, and when nut is dismantled, torque spanner will not bump to assembling plate surface, and then play guarantor
Shield is acted on.
3rd, back segment is outer-hexagonal structure, thus after installation, it is reusable, just need to can only be carried out using torque spanner
Dismounting, without destruction, a large amount of wastes for reducing material resources are conducive to cost-effective.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, the process portion is hollow outer-hexagonal structure or hollow quadratic structure.
Further, the inside of the process portion is interior hexagonal structure.
The beneficial effects of the invention are as follows：Carry out it is more convenient during assembly or disassembly, in nut with interlayer apart from too small
When, can be assembled by hexagonal structure in the inside of process portion.
Further, the convex spherical structure is adapted with concave spherical surface packing ring, and both are slidably matched, the working portion
The axis of axis and concave spherical surface packing ring, both axis phase mutual deviations are less than or equal to 7 °.
The beneficial effects of the invention are as follows：Further strengthen the effect of the detachable Closely locking nut component of self-adjusting.
