Description
Technical Field
The invention relates to the technical field of fastening devices, in particular to a nut combination with an anti-loosening function.
Background
In the prior art, the fastening of the connected object is usually realized by bolts, gaskets and nuts, and the connected object does not automatically loosen under the static load condition. However, there are inevitably shock, vibration, and variable load effects due to the working conditions of the coupling. Under the working conditions, the friction force between the thread pairs can disappear or reduce instantly; meanwhile, in the occasions of high temperature or large temperature change, the material can generate creep and stress relaxation, and the friction force is also reduced. Under the action of a plurality of times, the connection can be gradually loosened, and safety accidents are caused.
Disclosure of Invention
The invention aims to provide a nut combination with an anti-loosening function, which has the advantages of simple structure, reasonable design and convenience in use, aiming at the defects and shortcomings of the prior art.
In order to achieve the purpose, the invention adopts the technical scheme that: it comprises a disc-shaped nut body; the middle part of the disc-shaped nut body is provided with internal threads; the whole body of the disc-shaped nut inclines at an inclination angle of 2-15 degrees; the disc-shaped nut body is locked on the bolt;
further, it also comprises a dish-shaped gasket; the disc-shaped gasket is provided with a through hole matched with the internal thread on the disc-shaped nut body; the whole disc-shaped gasket is inclined at an inclination angle of 2-15 degrees; the disc-shaped nut body and the disc-shaped gasket are adjacently arranged and locked on the bolt; the dish-shaped gasket is arranged on the inner side of the dish-shaped nut body.
Furthermore, the disc-shaped nut body and the disc-shaped gasket are connected with the bolt in opposite taper directions;
furthermore, the front faces of the disc-shaped nut body and the disc-shaped gasket are oppositely arranged.
After adopting the structure, the invention has the beneficial effects that: the nut combination with the anti-loosening function can effectively prevent the nut from loosening under the action of impact, vibration and variable load, has enhanced safety, and has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.

Description of reference numerals:
1. a disc nut body; 2. a dish-shaped gasket; 3. a front side; 4. a bolt; 5. a first fastened piece; 6. a second fastened piece; 7. a common nut; 1-1, internal threads; 2-1 and through holes.
Detailed Description
The invention will be further described with reference to the accompanying drawings.
Referring to fig. 1-4, the embodiments of the present invention are as follows: it comprises a disc-shaped nut body 1 and a disc-shaped gasket 2; the middle part of the disc-shaped nut body 1 is provided with an internal thread 1-1; the disc-shaped gasket 2 is provided with a through hole 2-1 matched with the internal thread 1-1 on the disc-shaped nut body 1; the disc-shaped nut body 1 and the disc-shaped gasket 2 are integrally inclined, and the inclination angle alpha is 7 degrees; the front faces 3 of the disc-shaped nut body 1 and the disc-shaped gasket 2 are opposite and locked on the bolt 4, and the disc-shaped gasket 2 is arranged on the inner side of the disc-shaped nut body 1;
when the anti-loosening nut is used, the bolt 4 penetrates through the first fastened piece 5 and the second fastened piece 6 and is locked by the common nut 7, then the anti-loosening nut combination disclosed by the invention is screwed into the bolt 4 and is tightened by a certain torque, so that the common nut can be effectively prevented from loosening under the actions of impact, vibration and variable load, and the safety is enhanced.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
