[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is used for inserting and fixing a buffer rubber in a through hole of a required metal fitting or for inserting and fixing a rubber stopper.

[0002]

[Prior art]

 Conventionally, as means for fitting and fixing buffer rubber, rubber plug, etc. to the through hole of the required object, adhesive is applied, or the retaining ridge provided on the through hole is fitted to the retaining ridge. It is common practice to fit the ridges and ridges into each other while forcibly pushing in the cushioning rubber and rubber plug that have the ridges to prevent them from physically coming off.

[0003]

[Disadvantages of the prior art]

 However, when using an adhesive, it is inconvenient because the adhesive force may be weakened and the adhesive may come off due to the impact of long-term use of buffer rubber or the like. In addition, the physical fitting method of the ridges and the ridges has a drawback that the cushioning rubber and the rubber plug are difficult to push and work efficiency is poor.

[0004]

[Problems to be solved by the device]

 Let's improve work efficiency by smoothly and securely inserting a recessed rubber cushion, rubber plug, etc. into the through hole with a retaining ridge on the inner wall surface of the required object without using an adhesive. It is what

[0005]

[Means for Solving the Problems]

 A description will be given of an embodiment in which an elastic rubber as a cushioning rubber is inserted and embedded in the rotary metal fitting 2 in the door core metal fitting 1 of FIG. 3, and the rotary metal fitting 2 is used as the insert-embedded body 3. 3 and an elastic rubber body 4, the embedded body 3 has an insertion through hole 5 formed therein, and a retaining ridge 7 is provided in the middle of the inner wall surface 6 of the insertion through hole 5. The elastic rubber body 4 is provided with a buffer portion 8 at the head thereof, and a retaining portion is provided in the middle of the shaft portion 9 corresponding to the insertion through hole 5 and the retaining protrusion 7 respectively. A recess 10 is provided, and a thin pull-out shaft portion 11 which can be inserted into the insertion through hole 5 is extended at the insertion-side tip of the shaft portion 9 so that the periphery of the insertion-side tip of the shaft portion 9 is tapered. It will be as.

Although not shown, the inserted implantable body 3 may be metal fittings, plastics, wood, etc. outside thereof, and can be embodied when elastic rubber is used as a plug body. The head portion of 4 may be replaced with the buffer portion 8 to form a plug portion.

Further, the lid of the container can be appropriately used as the embedded body 3 to be inserted and attached to the handle made of elastic rubber.

[0008]

[Action]

 The present invention is constructed as described above, and in order to use this, first the insertion shaft portion 11 of the elastic rubber body 4 is inserted into the insertion through hole 5 and the shaft portion 9 is lightly pushed. After that, by forcibly pulling out the pull-out shaft portion 11 protruding downward of the insertion through hole 5, the shaft portion 9 enters the smooth, and the retaining groove 10 and the retaining projection 7 are fitted. . Further, the pull-out shaft portion 11 projecting downward is cut off.

[0009]

【effect】

 According to the present invention, as described above, since the pull-out shaft portion 11 which can be inserted into the insertion through hole 5 of the body to be inserted is extended at the insertion side end of the shaft portion 9 of the elastic rubber body 4, the pull-out shaft Insert the part 11 Insert the shaft part 9 into the through hole 5 and push the shaft part 9 lightly to make the drawer shaft part project to the opposite side. It is possible to smoothly pass through the retaining ridge 7 of the through hole 5 to fit the ridges and the ridges to each other, so that quickness and certainty of the work can be achieved. After fitting, the extraction shaft is exposed to the outside, so it can be easily cut off.
