Abstract
The invention discloses a locking nut. The locking nut is characterized by comprising a main nut and a secondary nut, one end of the main nut is an ordinary nut, the other end of the main nut is a hexagonal cavity with flanges, the secondary nut is an internally embedded nut with a gradually changing thread and of a slope structure, the secondary nut is embedded in the hexagonal cavity and is riveted by the flanges in a pressing mode, the secondary nut is in interference fit with the hexagonal cavity, and the flanges are riveted to the slope structure. Compared with the prior art, the locking nut has the advantages of being simple in structure, good in anti-vibration and anti-loosening effect, not prone to connection failures, long in service life and capable of effectively preventing a screw from loosening, and bringing convenience to assembly and use of products.
Description
Technical field
The present invention relates to technical field of fastening, especially a kind of lock nut using under vibration operating mode.
Background technique
Screw, nut are used widely in all trades and professions as topmost fastening piece, but under the environment of vibration, use easily generation screw, nut to get loose, so that the fastening inefficacy of link.For this reason, in industry, screw, nut are done to a lot of locking improvement, respectively had its pluses and minuses.The anti-loose structure of prior art exist screw assembling and dismounting very inconvenient, anti-loosing effect is poor, and preparation process and cost high, working life is short.
Summary of the invention
The object of the invention is a kind of lock nut designing for the deficiencies in the prior art, adopt mother nut flange to rivet the antivibration anti-loose structure of attached nut, effectively prevent getting loose of screw, screw is connected with nut and is difficult for losing efficacy, be very easy to assembling and the use of product, long service life, further reduces production costs, and enhances productivity.
The concrete technological scheme that realizes the object of the invention is: a kind of lock nut, be characterized in that this lock nut is made up of main body nut and annex nut, and described main body nut one end is hexagon nut, the other end is the hexagon cavity that is provided with flange; Described annex nut is to be provided with to become the gradually hexagonal embedded nut of screw thread and slope structure, slope structure is arranged on annex nut one end, in the hexagon cavity of annex nut embedding main body nut, pressed by flange, annex nut was to win to coordinate with hexagon cavity, and flange and slope structure are riveted joint.
Described gradual change screw thread is the screw thread arranging on cone shape hole, and its tapering is 1.5 °.
The material of described annex nut is PC or PTFE engineering plastics.
The present invention compared with prior art has good antivibration anti-loosing effect, simple in structure, and screw was difficult for losing efficacy with being connected of nut, the loosening of screw be can effectively prevent, assembling and the use of product are very easy to, long service life, further reduce production costs, enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is main body nut structure schematic diagram;
Fig. 3 is main body nut schematic perspective view;
Fig. 4 is annex nut structure schematic diagram;
Fig. 5 is annex nut schematic perspective view;
Fig. 6 is that the present invention specifically applies schematic diagram.
Embodiment
Consult accompanying drawing 4 ~ 5, described annex nut 3 becomes the gradually hexagonal embedded nut of screw thread 31 and slope structure 32 for being provided with, and slope structure 32 is arranged on annex nut 3 one end faces; The screw thread of described gradual change screw thread 31 for arranging on cone shape hole, its tapering is 1.5 °; The material of described annex nut 3 is PC or PTFE toughness and the good engineering plastics of wear resistance.
Consult accompanying drawing 6, the present invention is fastenedly connected with screw 2 like this: because hexagon nut 11 and screw 2 are common standard screw thread, annex nut 3 is 1.5 ° of changes nonstandard screw threads gradually, when screw 2 is screwed into after the present invention, screw 2 is being connected that standard thread coordinates with hexagon nut 11, screw 2 and being threaded that annex nut 3 is interference fit, can play the reliability of extraordinary fastening locking effect and connection.
More than just the present invention will be further described, and not in order to limit this patent, all is the present invention's equivalence enforcement, within all should being contained in the claim scope of this patent.
Claims (3)
1. a lock nut, is characterized in that this lock nut is made up of main body nut and annex nut, and described main body nut one end is hexagon nut, and the other end is the hexagon cavity that is provided with flange; Described annex nut is the hexagonal embedded nut that is provided with gradual change screw thread and slope structure, slope structure is arranged on annex nut one end, in the hexagon cavity of annex nut embedding main body nut, pressed by flange, annex nut was to win to coordinate with hexagon cavity, and flange and slope structure are riveted joint.
2. lock nut according to claim 1, is characterized in that described gradual change screw thread is the screw thread arranging on cone shape hole, and its tapering is 1.5 °.
