Abstract

PURPOSE:To intrude an adhesive tape into a space defined between a male and a female screw so as to prevent play. looseness and abnormal noise from being generated by sticking the adhesive tape to either one of the male and female screws, and screwing the male and female screws to each other in such a manner that the adhesive tape is wound in between the male and female screws. CONSTITUTION:A female screw 3 is threaded at the inner circumferential surface of the upper portion of a pipe-like supporting member 2 fixed at the lower end thereof to a base member 1. The female screw 3 is screwed to a male screw 5 threaded at the outer peripheral surface of the lower portion of an upper supporting member 2'. An adhesive tape 4, where an adhesive material 4b is applied onto one surface of a tape-like material 4a, is stuck to the outer peripheral surface of the male screw 5. The male and female screws 5, 3 are screwed to each other in such a manner that the adhesive tape 4 is wound in therebetween. Consequently. the adhesive tape 4 can be intruded into a space defined between the male and female screws 5, 3, thereby preventing play, looseness and abnormal noise from being generated between the male and female screws 5, 3.

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screwing structure and a screwing method for preventing play, loosening, generation of abnormal noise, etc. between a male thread and a female thread.

0002

2. Description of the Related Art When a male thread and a female thread are screwed together, play, loosening, and abnormal noise may occur between the male thread and the female thread depending on the environment of use. As a measure to prevent this, a method is conventionally known in which a liquid or cream-like substance is introduced between the male thread and the female thread, and the substance is solidified between the male thread and the female thread.

0003

[Problems to be Solved by the Invention] However, in the above conventional method, (a) it takes time for the substance to solidify, and if an external force is applied during the solidification, the male thread and the female thread may not be threaded together as desired. It is easy to move relative to the alignment position (
(b) Once the substance solidifies, the male thread and the female thread cannot be rotated relative to each other at all, resulting in problems such as the inability to adjust the position or redo the screwing operation.

The present invention has been made in view of the above circumstances, and provides a screw connection that can prevent rattling, loosening, generation of abnormal noise, etc. between a male thread and a female thread without causing the above-mentioned conventional problems. The purpose is to provide a structure and a screwing method.

[0005]

[Means for Solving the Problems] The threaded structure according to the present invention is provided by attaching an adhesive tape made by applying an adhesive to at least one surface of a tape-like material to the circumferential surface of a male or female screw. The male screw and the female screw are screwed together so that the adhesive tape is wound between the male screw and the female screw.

[0006] In the screwing method according to the present invention, an adhesive tape made by applying an adhesive to at least one surface of a tape-like material is applied to the circumferential surface of a male screw or a female screw, and this adhesive tape is attached to the male screw. The male screw and the female screw are screwed together so as to be caught between the male screw and the female screw.

[0007]

[Operation] In the present invention, the adhesive tape is wound between the male thread and the female thread, and the tape-like material and adhesive that make up the adhesive tape enter the gap between the male thread and the female thread. Play or looseness between the male and female threads,
It is possible to prevent abnormal noises, etc.

[0008]The moment the adhesive tape enters the gap between the male and female screws, it becomes difficult for the male and female screws to move relative to each other, so even if an external force is applied, the male and female screws will not move. There is no possibility that the screws and screws will move relative to each other from the desired screwing position. In addition, even after the adhesive tape enters the gap between the male and female screws, strong torque can be applied to rotate the male and female screws relative to each other at any time to adjust the position or redo the screwing process. It can be performed.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below based on embodiments shown in the drawings.

1 to 4 show an embodiment of the screwing structure and screwing method according to the present invention.

In this embodiment, a pipe-shaped support member 2 is attached to the base member 1 . This support material 2
A female thread 3 is cut on the inner peripheral surface of the upper end. The adhesive tape 4 is made by applying an adhesive 4b to one side of a tape-like material 4a made of cellophane, vinyl, cloth, or the like, as shown in FIG. The adhesive tape 4 was attached to the circumferential surface of the male screw 5 as shown in FIGS. Screw the male screw 5 and female screw 3 together as shown in the figure.

[0012] As a result, the tape-like material 4a and the adhesive 4b constituting the adhesive tape 4 enter the gap between the male screw 5 and the female screw 3, thereby eliminating any play between the male screw 5 and the female screw 3. , loosening, generation of abnormal noise, etc. can be prevented.

In this case, the adhesive tape 4 is attached to the male screw 5.
As soon as the male screw 5 and the female screw 3 enter the gap between the male screw 5 and the female screw 3, it becomes difficult for them to move relative to each other. There is no possibility of relative movement from the alignment position. Furthermore, even after the adhesive tape 4 enters the gap between the male screw 5 and the female screw 3,
At any time, by applying strong torque, the male thread 5
By relatively rotating the female screw 3 and the female screw 3, it is possible to adjust the position and redo the screwing operation.

FIG. 5 shows another embodiment of the present invention. In this embodiment, an adhesive tape 4 is attached to the circumferential surface of the female screw 3, and this adhesive tape 4 is attached to the male screw 5 and the female screw 3. The male screw 5 and the female screw 3 are screwed together so that they are caught between them. In this embodiment as well, the same effects as in the previous embodiment can be obtained.

In each of the embodiments described above, the adhesive tape 4 is wrapped around the circumferential surface of the male screw 5 or the female screw 3 for half a turn.
Depending on the case, the adhesive tape may be wrapped more or less around the male or female thread.

Furthermore, in each of the above embodiments, the adhesive tape 4 is attached to only one place on the circumferential surface of the male screw 5 or the female screw 3, but depending on the situation, the adhesive tape may be attached to the circumferential surface of the male or female screw. It may be attached to multiple locations on the circumference.

Furthermore, in the present invention, the shapes of the male thread and the female thread are not limited to those in the embodiments.

Further, in the above embodiment, the adhesive tape 4 coated with the adhesive 4b on only one side is used, but in the present invention, an adhesive tape coated with the adhesive on both sides may also be used. good.

[0019]

As described above, the present invention can (a) prevent rattling, loosening, generation of abnormal noise, etc. between the male screw and the female screw.

(b) The moment the adhesive tape enters the gap between the male and female screws, the male and female screws become relatively difficult to move, so even if an external force is applied, the male and female screws will not move. There is no possibility that the screw will move relative to the desired screwing position.

(c) Even after the adhesive tape enters the gap between the male and female screws, the male and female screws can be rotated relative to each other by applying strong torque at any time to adjust the position or tighten the screws. Collaborative work can be redone. It is possible to obtain excellent effects such as
