Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In addition, the preferred embodiments of the present invention will be described below, but it is needless to say that the technical idea of the present invention is not limited thereto and can be variously modified by those skilled in the art.

First, the configuration of an elastic deformation nut for unlocking according to an embodiment of the present invention will be described.

As shown in FIG. 1, the resiliently deformable nut for unlocking according to the embodiment of the present invention includes a nut body 10 and an elliptical screw hole 12 provided in the nut body 10.

2 to 4, it is preferable that the nut body 10 has an angular outer surface in order to facilitate the pressing of the outer surface when the elliptical or bore 12 is machined. For example, the external shape of the nut body 10 is preferably hexagonal.

The elliptical screw hole 12 is formed in such a manner that the width between both outer sides of the nut body 10 which is pressed by either one of the opposite outer side surfaces or both outer side surfaces of the nut body 10 against each other is in a shrunk deformation state, Machining the screw. The nut body 10, which has been shrunk and deformed, is restored to its original state when both sides of the nut body 10 are being pressed with a circular or square hole and the pressurized state of both outer side surfaces of the nut body 10 is released, An elliptical or bore 12 can be formed in the nut body 10 because it is deformed into an elliptical or bore hole 12.

On the other hand, the outer surface of the nut body 10 is provided with a pressing groove 13. The pressurizing grooves 13 are formed in the height direction of the outer side of the nut body 10. The pressing grooves 13 may be provided on the outer surfaces of the nut body 10, respectively. At least one of the pressing grooves 13 may be provided on each of the outer surfaces of the nut body 10. It is preferable that the pressing groove 13 is a concave groove having a round shape as a pressing point of the nut body 10. [ The contact pressure applied to the nut body 10 can be adjusted by changing the size and depth of the round pressing groove 13 provided in the nut body 10. [

One or more simple grooves 14 may be provided on the outer surface of the nut body 10 except for the pressurizing grooves 13. When the simple groove 14 is provided in the nut body 10, the elastic deforming nut can be deformed without increasing the force. That is, when there is no simple groove 14 in the nut body 10 when the elastic deforming nut is pressed by pressing the pressing grooves 13 provided on both side surfaces of the nut body 10, there is a great deal of force for deforming the elastic deforming nut . However, in the case of the simple groove 14, since the deformation is performed around the simple groove 14, the elastic deformation nut is deformed without applying much force as compared with the case where the simple groove 14 is not formed in the nut body 10 . Of course, as the simple groove 14 is deeply pushed into the nut body 10, the force is reduced when the elastic deforming nut is deformed.

1 to 4, the resiliently deformable nut according to the embodiment of the present invention is shown as a hexagon nut, but the present invention is not limited thereto. An angled nut that can press both outer surfaces facing each other, such as a quadrangle, or a nut that is flat in both outer surfaces facing each other, or the like.

On the other hand, an elastic deforming nut can be manufactured by using a material for making a nut as well as a material for making a general nut.

The following describes the configuration of a deformable socket for the fabrication of an elastic deformation preventing nut for unlocking.

The deformable socket is screwed to a bolt which is an object to be assembled of an elastic deforming nut for preventing loosening of an elliptical or hollow hole 12 formed by machining and machining an elliptical or hollow hole 12 in a nut body 10 coupled to a receiving space 21 It acts as a tool to enable.

Specifically, the deformable socket includes a deformable socket body 20, a receiving space 21 provided inside the deformable socket body 20, a coupling hole 22 formed symmetrically on the left and right sides of the upper surface of the deformable socket body 20, A pressing member 23 coupled to the deformable socket 20 and a screw fastening hole 24 provided on both outer sides of the deformable socket 20 press the pressing member 23 so that the pressing member 23 is coupled to the receiving space 21 And a protrusion 26 provided on the upper surface of the deformable socket body 20 so as to press both outer side surfaces of the nut body 10 facing each other.

The deformable socket body 20 is not limited to the outer shape but is preferably a cylindrical shape larger than the nut body 10 so that the nut body 10 can be housed therein rather than the angular shape.

The accommodating space 21 is formed in a shape conforming to the outer shape of the nut body 10 to be accommodated. For example, when the nut body 10 is hexagonal, it is preferable that the accommodation space 21 also has a hexagonal shape. The accommodating space 21 is formed inside the deformable socket body 20 and extends upward from the bottom surface of the deformable socket body 20 so as to accommodate the nut body 10.

The coupling holes 22 are symmetrically formed on both left and right sides with respect to the center of the upper surface of the deformable socket body 20. 4, the engaging hole 22 formed on the upper left side of the deformable socket body 20 is formed in the shape of "┣ ", and the right engaging hole 22 formed on the upper right side of the deformable socket body 20, (22) is formed in the shape of "┫ ". The engaging holes 22 are machined in the vertical direction from the upper surface of the deformable socket body 20 toward the bottom surface.

A pressing gap 221 is provided between the engaging hole 22 and the rear end of the pressing member 23 when the pressing member 23 is engaged with the engaging hole 22 and the pressing screw 221 25 to press the pressing member 23. It can be confirmed whether or not the pressing member 23 is correctly pressed through the pressurizing gap 221. The pressing member 23 is pressed until the pressurizing gap 221 disappears, so that unnecessary excessive force can be prevented from acting on the pressing member 23.

The pressing member 23 is formed in a shape corresponding to the engaging hole 22 and is coupled to the engaging hole 22 in a corresponding manner. The pressing member 23 includes a rear end 231 and a front end 232. [ The rear end portion 231 is in direct contact with the pressing screw 25. The rear end portion 231 is pressed by the pressing screw 25. The tip portion 232 is positioned to face the side surface of the nut body 10.

The distal end portion 232 is formed extending from the rear end portion 231. The front end portion 232 is formed to have a width narrower than the lateral width of the rear end portion 231. It is preferable that the distal end surface of the distal end portion 232 is formed in a rounded shape so as to be closely contacted with the round pressing groove 13 of the nut body 10. [ At least one tip portion 232 is formed.

The screw fastening holes 24 are formed on both sides of the outer side of the deformable socket body 20. The screw holes 24 are provided in the horizontal direction. A press-fitting screw (25) is fastened to the screw fastening hole (24). The screw fastening hole 24 is in communication with the fastening hole 22 so that the pressing screw 25 is screwed into the screw fastening hole 24 so as to press the pressing member 23. The screw fastening holes 24 are located on both outer sides of the nut body 10 accommodated in the accommodation space 21. [

The pressing screw (25) is fastened to the screw fastening hole (24). The pressing screw 25 presses the outer side surfaces of the nut body 10 received in the receiving space 21 by pressing the pressing member 23 while moving forward along the screw connecting hole 24. [ The rear end surface of the pressing screw 25 is provided with a fastening hole 251 through which a fastening device such as a wrench can be inserted. The fastening hole 251 is preferably a hexagonal fastening hole.

On the upper surface of the deformable socket body 20, a protrusion 26 is provided. The projecting portion 26 is formed to protrude upward from the upper surface of the deformable socket body 20. The projecting portion 26 is preferably formed at the center of the deformable socket body 20. The projections 26 can be used for applications such as supports or handles.

The following describes the method of machining an elastic deformation nut for loosening using a deformable socket.

The nut body 10 to be machined is coupled to the receiving space 21 of the deformable socket body 20 as shown in Figs. Then, the pressing member 23 is engaged with the coupling hole 22. In this state, the pressure screw 25 is fastened to the screw fastening hole 24.

The pressing screw 25 is moved in the direction of the arrow as shown in Fig. 4 so as to press the outer side surfaces opposite to each other of the nut body 10. The front end portion 232 of the pressing member 23 that is pressed against the pressing groove 23 of the nut body 10 and the front end portion of the pressing member 23 is in close contact with the pressing groove 13 of the nut body 10, 10) Press both sides. At this time, the pressing member 23 is pressed by the pressing screw 25 until the pressure gap 221 disappears. The pressing screw 25 may be tightened only by the pressure gap 221. It is possible to determine how much the pressing screw 25 should be pressed through the pressurizing gap 221, so that the pressing operation can be speeded up.

The widths of the opposite side surfaces of the nut body 10 facing each other are contracted by pressing of the pressing member 23. [ In this state, a round screw is machined in the center of the nut body 10. [ Then, the pressurized state of the nut body 10 is released by releasing the pressure screw 25. When the pressurized state is released, the shrunk nut body 10 is restored to its original state, and the circular or hollow hole is deformed into an elliptical screw hole.

When the machining process of the elliptical or bore hole 12 is once again arranged, the process proceeds sequentially as shown by the arrows in Fig. That is, as shown in the upper part of FIG. 5, when the both side surfaces of the nut body 10 facing each other are pressed, the nut body 10 is contracted and deformed. In this state, the circular screw hole 11 is machined in the center of the nut body 10. 5, when the pressing of the both side surfaces of the nut body 10 is released, the nut body 10, which was shrunk and deformed under pressure, is restored to its original shape so that the circular hole 11 is deformed into the ellipse or the hole 12 . 5, an elastic deforming nut for preventing loosening with an elliptical or bore hole 12 can be manufactured.

The following explains how to assemble an elastic deformation nut for loosening using a deformable socket.

As shown in Figs. 1 to 3, an elastic deformation nut having an elliptical or bore hole 12 to be an object to be assembled is coupled to the receiving space 21 of the deformable socket body 20. Then, the pressing member 23 is engaged with the coupling hole 22. In this state, the pressure screw 25 is fastened to the screw fastening hole 24.

As shown in Fig. 4, the pressing screw 25 is moved in the direction of the arrow to press the outer side surfaces of the resiliently deformable nuts opposed to each other. The tip end portion 232 of the pressing member 23 which is in contact with the pressing groove 13 of the elastic deformation nut is pressed against both sides of the elastic deforming nut Pressure. At this time, the pressing member 23 is pressed by the pressing screw 25 until the pressure gap 221 disappears. The pressing screw 25 can be tightened by the pressing gap 221, so that the pressing operation can be performed quickly.

As the widths of opposite side surfaces of the resiliently deformable nuts are contracted by the urging of the pressing member 23, the elliptical or hollow hole 12 is deformed into the circular or hollow 11. In this state, a deformed circular hole or hole 11 is screwed to the bolt to be assembled. Then, release the pressing screw (25) to release the pressing state of the elastic deformation nut. When the pressurized state is released, the shrunk elastically deformable nut is restored to its original state, and the circular or hollow hole is deformed into an elliptical screw hole and closely adhered in the radial direction of the bolt.

When the assembling process of the elastic deformation nuts is once again summarized, the process proceeds sequentially as shown by the arrows in Fig. 6, when the opposite sides of the elastic deforming nut are pressed against each other, the elastic deforming nut is shrunk and the elastic deforming nut is deformed to the elliptical shape or the hollow shape of the elastic deforming nut 12 are deformed into circular or hollow holes 11.

Screw the deformed circular screw hole (11) into the bolt to be assembled. 6, when the pressing of both sides of the elastic deforming nut is released, the elastic deforming nut, which was shrunk and deformed under pressure, is restored to its original shape, and the circular hole 11 is deformed into the elliptical shape or the hole 12. In the process of being deformed from the round hole 11 to the elliptical shape or the hole 12, the elliptical or hollow hole 12 is tightly adhered in the radial direction of the bolt thread.
