[Detailed Description of the Invention] <Field of rain benefits for industrialists> This invention relates to a detent structure for nuts.

<Prior art> Related to the detent structure of nuts 1 There are many types 9
For example, Uf+/to (with a fulction ring)
, Aero) Knaft (a nylon block is placed on the screw thread to take advantage of its spring action), double-type detent nut (a nut with a set of convex and convex shapes), sub-type washer nut (a nut with a washer) There are many such as built-in ones), but all of them have a structure that applies pressure to a part of the screw thread on one side. However, there is no such thing that can apply a uniform force to the entire surface of the screw thread, and if this is done, it has the drawback of requiring a complicated structure, so there has been a need for a detent nut that is better than the current one.

(問題点を解決するため・、の手段〉 戻り止め効果を最も白くする手段は、おネジ。(Means for solving problems) The best way to achieve the whitest detent effect is with a male screw.

This problem can be solved by increasing the overall frictional force between the female threads, but current nuts have a constant diameter with respect to the opposing bolts, so only a force parallel to the axial direction can be applied. It is structurally impossible to apply a strong force perpendicular to the axial direction. As a means to make this possible, the diameter of the nut is slightly varied. In other words, it has a structure in which the nut material is wrapped in a spiral shape and the diameter of the bolt can be slightly opened by the contact pressure (pressure from inside) with the bolt. I used a method that didn't exist.

(Function) The inner diameter of the nut is slightly changed, and the nut structure is formed into a spiral shape or vertically divided shape.A screw is cut into this W4 artificial tree.Is the diameter of the nut the same as the bolt thread diameter? It must be made with a small diameter and a force of 1'.

The nut acts and moves while fully contacting the threaded part of the bolt. Therefore, frictional force is constantly applied and no loosening occurs, and the opening frame is set within the elastic limit of the material, so it can be reused. This will be explained with reference to the side view shown in FIG. - As an example, as shown in FIG. 2, the nut material (1) of appropriate thickness (B) is wound into a screw shape (2) as shown in FIG. 8! (screw 1
) indicates a state in which the rolls are tightly rolled, but they may be rolled with a little space between them, and the thickness can be adjusted as desired.

<Effects of the invention> Nuts with 7-structure (threaded or vertically split) elastically utilize internal pressure as friction by manipulating the screw diameter, which could not be done conventionally, and bring O, screws, and female screws into close contact with the D grip. This is an elastic nut that applies a force perpendicular to the axial direction of the bolt, and easily achieves a detent effect that was previously impossible to achieve. Also, because it is more effective, it is lighter than conventional nuts!
, miniaturization is also possible, the benefit of which is the construction of a detent nut with a large threaded or longitudinal structure.

For nuts for screws, the nut is formed into a spiral or vertically split shape from an elastic material, the inner diameter of the molded body is the same as or slightly smaller than the diameter of the bolt, and the screw is attached so that the nut is tightly attached to the bolt. The structure of the detent nut is characterized by elastic minute movement of the nut diameter, which constantly applies tightening force from the circumference.
