본 고안은 출원인이 선출원한 실용출원 제 97-3334호에서 양쪽배관의 이음부분에 일단이 절취되어 사이간격이 형성된 경질링이나 또는 상, 하부 두개체로 분리된 경질링을 이음부분의 양쪽외경에 끼우고 상, 하부커플링의 양쪽 내주면에는 양측경사면홈을 형성시켜서 이에 경질링의 상부가 협착되도록 하여 상,하부 커플링을 볼트, 너트로서 체결시켜서 경질링이 내향으로 압축되면서 경질링의 내경면에 형성시킨 수개의 톱니형돌조가 양쪽배관의 이음부분외경을 고정시키는 것으로 철강재인 양쪽배관의 이음부분외경을 배관강도보다 강한 경질링의 톱니형돌조로서 압축시켜 양쪽배관을 연결되게 고정시키나 이를 압축하고 있는 상,하부 커플링을 볼트, 너트로서 체결시 내향으로의 압축력이 약하거나 또는 연결시킨 양쪽배관이 외부의 충격을 받았을때 이음부분의 외경을 고정하고 있는 톱니형돌조가 배관외경에서 미끄러질 수 있는 결점이 있었다.In the present invention, the applicant filed an application filed 97-3334, one end of which is cut off at the joints of both pipes, or a hard ring having a gap between the upper and lower two bodies is inserted into the outer diameters of the joints. On both inner circumferential surfaces of the upper and lower couplings, both inclined surface grooves are formed so that the upper part of the hard ring is squeezed thereto, and the upper and lower couplings are tightened as bolts and nuts. Several toothed protrusions fix the outer diameter of the joints of both pipes, and the outer diameters of the joints of both pipes, which are steel, are compressed as toothed protrusions of hard rings, which are stronger than the pipe strength. When the upper and lower couplings are bolted and nuts, the compression force inwardly is weak or both pipes connected to each other may be impacted externally. There was a drawback that the serrated ledges fixing the outer diameter of the joint could slide on the pipe outer diameter.
본 고안에서는 이와같은 문제점을 개선하기 위하여 상,하부 커플링의 내주면 양쪽에 경질링 삽입홈을 형성시켜 반원형이 되게 두개체로 절단이 되고 각 내경면의 양쪽에 톱니형 돌조가 형성된 상,하부 경질링이나 또는 일단이 절취되어 사이간격이 형성되고 내경면의 양쪽에 톱니형 돌조가 형성된 경질링을 끼우고 이와 대응되게 이음부분 외경에는 톱니형홈을 수개 일치되게 형성시켜서 상,하부 커플링을 볼트, 너트로서 체결시 경질링의 내경면에 형성된 수개의 톱니형 돌조가 양쪽배관의 이음부분 외경에 형성된 수개의 톱니형홈에 치합되어 견고하게 고정이 되는 것으로 도면에 의거 상세히 설명하면 다음과 같다.In the present invention, in order to improve the above problems, the upper and lower hard rings are formed in the inner peripheral surface of the upper and lower couplings by cutting grooves on both sides to form a semi-circular shape, and the toothed protrusions are formed on both sides of each inner diameter surface. Inner or one end is cut off to form a gap between the inner diameter surface, and insert a hard ring formed with a tooth-shaped protrusion on both sides of the inner diameter, and correspondingly, the outer diameter of the joint is formed by matching a number of tooth-shaped grooves, bolts, nuts As shown in detail in accordance with the drawings that the number of tooth-shaped protrusions formed on the inner diameter surface of the hard ring is securely fixed to the number of tooth-shaped grooves formed in the outer diameter of the joint portion of both pipes.

In the well-known joint coupling to be fastened by the lower couplings 10 and 10a, hard ring inserting grooves 12 are formed on both inner circumferential surfaces of the upper and lower couplings so that they are cut into two pieces so as to be semicircular and each inner diameter The upper and lower hard rings 20 and 20a having toothed protrusions 21 formed on both sides of the surface are inserted or one end thereof is cut off to form a gap 22 between the inner surface and the toothed protrusions 21 on both sides of the inner diameter surface. To fit the hard ring 20 is formed to correspond to the outer diameter of the joint portion to form a number of tooth-shaped grooves (3) to match the upper and lower couplings 10, 10a as a bolt, nut when the teeth of the hard ring Shaped protrusion 21 is to be fixed to the toothed groove (3) of the outer diameter of the joint.
그리고 경질링(20)의 내경면중간에 사각형돌조(21')를 형성시키고 이와 대응되게 이음부분 외경에는 사각형홈(3')을 일치되게 형성시켜 조립시 치합시킬 수도 있는 것이다.In addition, a square protrusion 21 'may be formed in the middle of the inner diameter surface of the hard ring 20, and a square groove 3' may be formed in the outer diameter of the joint portion so as to correspond to each other.
