Description

A kind of double nuts structure with locking functions
Technical field
The utility model relates to nut fastening structure, is specifically related to a kind of double nuts structure with locking functions.
Background technique
In the production, life of people, bolt, nut widely use as link.But for the occasion having vibrations, loading direction and size to have larger change, the anti-loosing effect that single double nuts structure and nut add spring washer structure is just had a greatly reduced quality.Time one length will cause nut loosening, especially for some visual plants and important workpiece once nut loosening cause can disengaging between workpiece, or cause large security incident because of loosening of connection, so seem particularly important at the anti-loosing effect of special occasions raising nut and bolt.
Model utility content
For above-mentioned technical problem, the utility model provides a kind of double nuts structure with locking functions, proposes technological innovation to the structure of nut, effectively can prevent nut loosening.
The technical solution of the utility model is:
A kind of double nuts structure with locking functions, comprise locking nut, bearing screwed cap, compression spring, described locking nut and bearing screwed cap center are respectively equipped with tapped hole, it is characterized in that: described bearing screwed cap top center is provided with a cylindrical bump, the center of described cylindrical bump is provided with tapped hole, the tapped hole of described cylindrical bump is identical with the tapped hole of described bearing screwed cap, the circumference of the outer surface of described cylindrical bump is provided with outside thread, a groove matched with the cylindrical bump of described bearing screwed cap is provided with bottom described locking nut, groove bottom described locking nut is provided with internal thread, the tapped hole position of described locking nut is corresponding with the tapped hole position of bearing screwed cap, the tapped hole center of circle of described locking nut is identical with the center of circle of its bottom groove, compression spring is provided with between described bearing screwed cap and locking nut.
Further, described locking nut and bearing screwed cap have the screw thread of two kinds of different sizes, and the tapped hole screw thread of described locking nut and bearing screwed cap matches with bolt, and the boss outside thread of described bearing screwed cap matches with the groove internal thread of described locking nut.
Further, two kinds of screw threads of described locking nut and bearing screwed cap adopt identical pitch, and the boundary dimension of described locking nut and bearing screwed cap selects state's dimensioning.
The beneficial effects of the utility model:
Double nuts structure of the present utility model in use, be equipped with after the double nut of spring washer and bolt screw, two nuts not only and between bolt, form pairs of anti-loose nut structure, simultaneously between two nuts screw thread define again with compression spring together with anti-loose structure, thus reach dual locking object.The utility model is applicable to vibrations, loading direction and size the equipment of larger change and the connection of two workpiece, is specially adapted to the occasion that the interval between bolt does not strictly limit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model locking nut structure schematic diagram.
Fig. 3 is the utility model bearing screwed cap structural representation.
Fig. 4 is the utility model compression spring structural representation.
Embodiment
As Figure 1-4, a kind of double nuts structure with locking functions of the present utility model, comprise locking nut 1, bearing screwed cap 2, compression spring 3, described locking nut 1 and bearing screwed cap 2 center are respectively equipped with tapped hole 11 and 22, it is characterized in that: described bearing screwed cap 2 top center is provided with a cylindrical bump 21, the center of described cylindrical bump 21 is provided with tapped hole, the tapped hole of described cylindrical bump 21 is identical with the tapped hole 22 of described bearing screwed cap 2, the circumference of the outer surface of described cylindrical bump 21 is provided with outside thread, a groove 12 matched with the cylindrical bump 21 of described bearing screwed cap 2 is provided with bottom described locking nut 1, groove 12 bottom described locking nut 1 is provided with internal thread, tapped hole 11 position of described locking nut 1 is corresponding with the position of the tapped hole 22 of bearing screwed cap 2, tapped hole 11 center of circle of described locking nut 1 is identical with the center of circle of its bottom groove 12, compression spring 3 is provided with between described bearing screwed cap 2 and locking nut 1.
Further, described locking nut 1 and bearing screwed cap 2 have the screw thread of two kinds of different sizes, the screw thread of the tapped hole 11 and 22 of described locking nut 1 and bearing screwed cap 2 matches with bolt, and the outside thread of the boss 21 of described bearing screwed cap 2 matches with groove 12 internal thread of described locking nut 1.
Further, two kinds of screw threads of described locking nut 1 and bearing screwed cap 2 adopt identical pitch, and the boundary dimension of described locking nut 1 and bearing screwed cap 2 selects state's dimensioning.
The utility model is when assembling, and first compression spring 3 is put into locking nut 1, two nuts screw up mutually one to two circle, screws in bolt, after nut 2 to be lifted screws with bolt, then locking nut 1 and bearing screwed cap 2 and bolt is screwed simultaneously.Bearing screwed cap 2 Main Function carries, and locking nut 1 and compression spring 3 major function are locking.
