Description

Nut combination with locking function

Technical Field

The utility model relates to a fastener technical field, concretely relates to nut combination with locking 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.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a nut combination with locking function of simple structure, reasonable in design, convenient to use to prior art's defect and not enough.

In order to achieve the above object, the utility model adopts the following technical scheme: 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 the structure is adopted, the utility model discloses beneficial effect does: a nut combination with locking function, can effectively prevent to strike, vibration, become that the load effect is not hard up down the nut, the security reinforcing, and have simple structure, set up reasonable, cost of manufacture low grade advantage.

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 present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1-4, the present invention is embodied 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;

during the use, pass bolt 4 earlier by fastener one 5 and by fastener two 6, lock with ordinary nut 7, will again locknut combination screw in bolt 4, with certain moment of torsion screw up can, can effectively prevent to strike, vibrate, become that ordinary nut is not hard up under the loading effect, the security reinforcing.

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 replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
