Description

A kind of double fluting self-locking nut
Technical field
This utility model relates to a kind of structure connecting securing member, belongs to field of mechanical technique, more specifically Say and relate to a kind of double fluting self-locking nut.
Background technology
In being connected with each other of connector, threaded is the most universal and conventional one, current spiral shell The anti-loose method that stricture of vagina securing member connects is divided into three basic forms of it: non-removable locking, be mechanically fixed Locking and the increasing friction force of part locking.Non-removable locking be a kind of use weld, bond or The modes such as punching point riveting change into non-dismountable threaded anti-loose method by the most threaded, Its shortcoming is that threaded fastener can not be reused;The locking of mechanical fixed part is to utilize mechanical fixed part Make to fix between screw element and connected piece or between screw element and screw element and lock, loosen to prevent, Shortcoming is to increase the weight being fastenedly connected, and manufactures and installs trouble, it is impossible to carry out motor-driven installation, so Relatively costly;The locking utilization of increasing friction force increases between screw thread or bolt (screw) head and nut end The frictional force in face or simultaneously increase both methods of frictional force to reach locking purpose, this locking Method is poorer than the reliability of above-mentioned first two method.At present between parts be connected by anti- Loose measure formula have double nut assembly method, cone pressure holds locking clamp device tightly, bolt adds split pin mode, Plain nut adds stop washer mode, plain nut adds the mode of plain cushion spring washer etc..Double nut assembling makes Screw thread between two height of nuts produces small elastic deformation and obtains additional friction force and locking, But this kind of mode needs two nuts every time, workload is big, and workpiece weight increases.Cone pressure is held tightly anti- Pine clamp device needs to tighten mother nut and locking nut two parts part, and workload is big.Bolt is increased Mouth pin mode needs assembled in situ split pin, and workload increases, and encounter problems dismounting inconvenience.Common spiral shell Mother adds stop washer mode for the angle of packing ring and highly desirable field operation, is not easy to control.General The mode anti-loosing effect that logical nut adds plain cushion spring washer etc. is bad.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides the self-locking of a kind of double fluting Nut.
This utility model is achieved through the following technical solutions: a kind of double fluting self-locking nuts, including Nut body, is provided with the column of protrusion, in column on an end face of described nut body It is provided with the screwed hole communicated with the screw thread on nut body, the cylinder of column is provided perpendicular to The groove of column axis, the degree of depth of described groove is more than the semicircle of column.
In such scheme, described groove be set to two and on column lateral symmetry, two grooves are along post The axis misalignment of shape body.
In such scheme, optimizing structure as one, the notch of described groove extrudes along the axis of column Deformation.
In such scheme, another end face of described nut body is provided with packing ring, described packing ring with Nut body activity rivets.
In such scheme, the internal diameter of described packing ring is provided with annular protrusion, the end face of described nut body On be provided with the seam of protrusion, seam outward flanging blocks described annular protrusion.
In such scheme, described packing ring is butterfly gasket, the end face of packing ring is provided with radial many Bar fin.
Compared with prior art, it provides the benefit that this pair of fluting self-locking nut:
1, this utility model double fluting self-locking nut arranges symmetric double fluting, can make coupling mechanism force equiblibrium mass distribution On screw thread, make engagement tightr, be suitable for vibration and impact more violent application.
2, this utility model double fluting self-locking nut utilizes the tension force of butterfly gasket to provide lock for threaded Tight effect, makes locking self-locking effect more remarkable.
3, this utility model double fluting self-locking nut is installed simple, reusable, dismounts more convenient, More efficient.
Accompanying drawing explanation

In figure: 1. nut body, 2. column, 3. groove, 4. butterfly gasket, 5. fin, 6. annular Projection, 7. seam.
Detailed description of the invention
With specific embodiment, this utility model double fluting self-locking nut is made further below in conjunction with the accompanying drawings Describe:
Fig. 1 is the structural representation of this utility model double fluting self-locking nut, and Fig. 2 is the A-A of Fig. 1 Sectional view, in figure, this pair of fluting self-locking nut includes nut body 1, on a right side of nut body 1 It is provided with the column 2 of protrusion on end face, column 2 is provided with and the screw thread phase on nut body 1 Logical screwed hole, the cylinder of column 2 is provided perpendicular to the groove 3 of column axis, groove 3 deep Degree exceedes the semicircle of column.Groove 3 be set to two and on column 2 upper and lower lateral symmetry, two Individual groove 3 staggers along about the axis of column 2, and the notch of groove 3 extrudes change along the axis of column 2 Shape.The notching construction of this double fluting self-locking nut can realize splendid anti-loosing effect, its locking slot Form through Precision Machining, make female thread produce certain pitch difference.When bolt screws in, female thread returns Recovery has pitch, and elastic deformation occurs, and internal and external threads is tightly engaged by the elastic force of generation, makes nut Firmly it is self-locking on bolt.
Fig. 3 is the another kind of structural representation of double fluting self-locking nut, and Fig. 4 is the left view of Fig. 3, Fig. 5 is the partial enlarged drawing in Fig. 3 at B.In figure, the left side of nut body 1 also sets up Butterfly gasket 4, the internal diameter of butterfly gasket 4 is had to be provided with annular protrusion 6, the right side of nut body 1 On be provided with the seam 7 of protrusion, seam 7 outward flanging blocks annular protrusion 6, the end of butterfly gasket 4 Radial a plurality of fin 5 it is provided with on face.During double fluting self-locking nuts screw, butterfly pad The end face of circle 4 is pressed on by the surface of securing member without rotating.
This double fluting self-locking nut can make coupling mechanism force be evenly distributed on screw thread when screwing, and makes engagement Tightr, be suitable for vibration and the more violent application of impact, the setting of end face butterfly gasket make locking from Lock effect is more remarkable, and this pair of fluting self-locking nut is installed simple, and reusable, dismounting is more Convenient, more efficient.
The above, be only preferred embodiment of the present utility model, not makees this utility model Any pro forma restriction, although this utility model is disclosed above with preferred embodiment, but not In order to limit this utility model, any those skilled in the art, without departing from this utility model skill In art aspects, when method and the technology contents of available the disclosure above are made a little change or repair Decorations are the Equivalent embodiments of equivalent variations, as long as being the content without departing from technical solutions of the utility model, Any simple modification of above example being made according to technical spirit of the present utility model, equivalent variations With modification, still fall within the range of technical solutions of the utility model.
