Industry, such as electromechanical installation, building machinery, farm machinery every field are a kind of essential basic mechanical organs, each
Engineering product is actually required for using threaded fastener no matter its composition has mostly complexity.With other most of bind mode phases
Than the considerable advantage of threaded fastener is that it can dismantle and reuse.However, this is also the root place of problem, because
Threaded fastener is easy to happen from loose phenomenon.Since the industrial revolution, screw thread does not solve very well from loosening always one
Certainly the problem of.Existing technology is, existing to ask using the methods of locking plate, pin, nylon insertion, deformation screw thread, chemical gluing
Topic is the time for having delayed fastener that can voluntarily loosen to a certain extent, but loosens problem and do not solve at all.
Invention content
In order to overcome the deficiencies in the prior art, the utility model to provide a kind of nut that is locked of slotting.
The utility model is achieved through the following technical solutions：A kind of fluting is locked nut, including main nut and
A cylindrical body is stretched out in locking nut, one side end face of the main nut in the axial direction, is provided on the external cylindrical surface of cylindrical body outer
A small cylindrical body is stretched out in the end face of screw thread, cylindrical body again in the axial direction, and the outer diameter of the small cylindrical body is less than externally threaded spiral shell
Line path, the small cylindrical body and cylindrical body are both provided with the threaded interior hole with main nut with screw thread, are set in the small cylindrical body
It sets there are two the translot perpendicular to axis, the depth of the translot is more than the radius of small cylindrical body, and the opening of two translots is with axis
Line is symmetrical and two translots are interlaced；The locking nut is provided with the interior spiral shell to match with the external screw thread on main nut
Line is provided with limit shoulder on the internal thread, the via coaxial with internal thread, the diameter of via is additionally provided on locking nut
More than the Major Diam of the threaded interior hole of main nut, it is less than the outer diameter of the small cylindrical body.
In said program, the distance of the locking nut upper limit shoulder to internal thread outer end face is less than small cylinder on main nut
Distance of the shape body end face to external screw thread root.
In said program, one of translot is close to externally threaded end face in described two translots.
In said program, arc-shaped is arranged in the root of the translot, and the diameter of circular arc is more than the width of translot.
A kind of fluting of the utility model is locked nut compared with prior art, and advantage is：
1. reaching complete locking property under the top load motion state of the low vibrations of fastener or strong motion, workpiece itself is overcome
The limitation of state；
2. fluting is locked, nut utilizes the external force of locking nut, is compressed axially to the translot on main nut,
It forces locking nut to hold bolt tightly, plays locking effect.
3. a fluting is locked, nut is without using exterior part or chemical glue spreading method.

Fig. 3 is the structural schematic diagram of part 10 in Fig. 1.
In figure：1. main nut, 2. threaded interior holes, 3. external screw threads, 4. small cylindrical body external cylindrical surfaces, 5. small cylindrical body end faces,
6. translot, 7. arc-shapeds, 8. small cylindrical bodies, 9. cylindrical bodies, 10. locking nuts, 11. internal threads, 12. limit shoulders, 13. mistakes
Hole.
Specific implementation mode
The nut work that is locked below in conjunction with the accompanying drawings with specific embodiment fluting a kind of to the utility model is further retouched
It states：
Attached drawing is that a kind of fluting of the utility model is locked the structural schematic diagram of nut, and Fig. 2 is the structure of part 1 in Fig. 1
Schematic diagram, Fig. 3 are the structural schematic diagrams of part 10 in Fig. 1.In figure, this nut that is locked of slotting, including main nut 1 and locking
A cylindrical body 9 is stretched out in the upper surface of nut 10, main nut 1 in the axial direction, and external screw thread is provided on the external cylindrical surface of cylindrical body 9
3, a small cylindrical body 8 is stretched out in the end face of cylindrical body 9 again in the axial direction, and the diameter of small cylindrical body external cylindrical surface 4 is less than external screw thread 3
Diameter of thread, small cylindrical body 8 and cylindrical body 9 are both provided with the threaded interior hole 2 with main nut with screw thread, are set in small cylindrical body 8
It sets there are two the translot 6 perpendicular to axis, the depth of translot 6 is more than the radius of small cylindrical body 8, and the opening of two translots is with axis
Symmetrical and two translots are staggered in axis direction, and arc-shaped 7 is arranged in the root of translot 6, and the diameter of circular arc is more than translot
Width, a translot are close to the upper surface of cylindrical body 9.Locking nut 10, which is provided with, to match with the external screw thread 3 on main nut 1
Internal thread 11 is provided with limit shoulder 12 on the internal thread 11, the mistake coaxial with internal thread is additionally provided on locking nut 10
Hole 13, the diameter of via 13 are more than the Major Diam of threaded interior hole 2, are less than the outer diameter of small cylindrical body 4.Limit on locking nut 10
