Description

Anti-loosening nut
Technical Field
The utility model relates to a fastener technical field especially relates to an anti-loosening nut.
Background
The Nut is also called Nut (English: Nut) and is a fixing tool, the center of which is provided with a hole, and the inner side of the hole is provided with threads. The nut is often shared with the screw that the size matches to fixed joint portion, fixes through carrying out threaded connection with the bolt with the nut among the prior art, but the nut receives external power easily and rotates, like the vibration, causes the not hard up influence fixed effect of nut, causes the drop of junction, causes dangerous accident easily.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem of easy loosening in the prior art and providing a loosening prevention nut.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a locking nut that moves, includes coupling nut, coupling nut upper end both sides fixedly connected with montant, two the upper end fixedly connected with fixed plate of montant, the middle part position of fixed plate sets up threaded hole, threaded hole female connection has the threaded rod, the threaded hole all extends at the threaded rod both ends, threaded rod lower extreme fixedly connected with butt plate, butt plate is circularly, the piece is turned round to threaded rod upper end fixedly connected with, it is regular hexagon to turn round the piece.
Preferably, coupling nut lower extreme fixedly connected with connects the platform, it is regular hexagon to connect the platform, the thickness of connecting the platform is 1 with coupling nut's thickness ratio: 3.
preferably, the thread direction of the threaded rod is the same as the thread direction of the connecting nut.
Preferably, the lower surface of the abutting plate is provided with anti-skid grains at equal intervals.
Preferably, transition fit or interference fit is adopted between the threaded hole and the threaded rod.
The utility model provides a pair of locking nut that moves, beneficial effect lies in: through the design of threaded rod, screw hole, butt plate, wrench movement piece, with the butt plate butt in the upper end of bolt, when the nut receives vibrations to take place to rotate, play spacing effect, prevent that the nut from taking place the pine, cause dangerous accident.
Drawings
Fig. 1 is a schematic structural view of a loosening prevention nut according to the present invention;
fig. 2 is a top view of the anti-loosening nut of the present invention shown in fig. 1;
fig. 3 is a top view of the anti-loose nut abutting plate provided by the present invention.
In the figure: connecting nut 1, connection platform 2, butt joint board 3, fixed plate 4, piece 5, threaded rod 6, screw hole 7, montant 8, antiskid line 9 are turned round.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Example 1
Referring to fig. 1-2, a loosening-preventing nut comprises a connecting nut 1, wherein both sides of the upper end of the connecting nut 1 are fixedly connected with vertical rods 8, the upper ends of the two vertical rods 8 are fixedly connected with a fixing plate 4, the middle position of the fixing plate 4 is provided with a threaded hole 7, the threaded hole 7 is internally threaded with a threaded rod 6, the threaded hole 7 and the threaded rod 6 are in transition fit or interference fit, the two ends of the threaded rod 6 are respectively extended out of the threaded hole 7, the lower end of the threaded rod 6 is fixedly connected with a butt plate 3, the butt plate 3 is circular, the upper end of the threaded rod 6 is fixedly connected with a twisting block 5, the twisting block 5 is regular hexagon, the thread direction of the threaded rod 6 is the same as the internal thread direction of the connecting nut 1, the twisting block 5 is turned by a wrench to drive the threaded rod 6 to rotate the butt plate 3, so that, the resistance of the nut during rotation is increased, so that the limiting effect is achieved, and the nut is prevented from loosening.
When using, earlier with coupling nut 1 threaded connection on the bolt, fasten it, then twist the piece 5 of turning round through the spanner, drive threaded rod 6 and rotate, will drive butt joint board 3 and rotate, make 3 lower surfaces of butt joint board and the upper end looks butt of bolt.
Example 2
Referring to fig. 1-2, as another preferred embodiment of the present invention, the difference from embodiment 1 is that the lower end of the coupling nut 1 is fixedly connected with the coupling table 2, the coupling table 2 is a regular hexagon, and the thickness ratio of the coupling table 2 to the coupling nut 1 is 1: 3, the model of connecting platform 2 and coupling nut 1 is different, when fixing the nut, can adopt the spanner of different models to fix the nut.
Example 3
Referring to fig. 3, as another preferred embodiment of the present invention, the difference from embodiment 1 is that the lower surface of the butt plate 3 is equidistantly provided with the anti-slip patterns 9, and the design of the anti-slip patterns 9 increases the roughness of the lower surface of the butt plate 3, thereby increasing the friction force, being beneficial to increasing the resistance force and preventing the nut from rotating.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
