먼저, 도 4에 도시된 바와 같이, 제1 및 제2 고정부재(32,33)를 끼움부재(31)의 원통부(31a)에 형성한 복수개의 관통구멍(31c)에 각각 설치한 후, 원통부(31a)를 연결부(20)의 양쪽 연결구멍(21)의 안쪽둘레면에 각각 끼워 넣는다. 이때, 제1 및 제2 고정부재(32,33)의 측면과 관통구멍(31c)의 측면은 내측으로 갈수록 폭이 점점 작아지도록 형성된 것이므로, 제1 및 제2 고정부재(32,33)가 관통구멍(31c)을 관통하여 내측으로 빠질 염려가 없다.First, as shown in FIG. 4, the first and second fixing members 32 and 33 are respectively installed in the plurality of through holes 31c formed in the cylindrical portion 31a of the fitting member 31. The cylindrical portions 31a are inserted into the inner circumferential surfaces of both connecting holes 21 of the connecting portion 20, respectively. In this case, the side surfaces of the first and second fixing members 32 and 33 and the side surfaces of the through holes 31c are formed to become smaller in width toward the inner side, so that the first and second fixing members 32 and 33 penetrate. There is no fear of falling out through the hole 31c.

이어서 양쪽 끼움부재(31) 사이에 연결소켓(34)을 위치시킨 후, 연결소켓(34)의 양쪽 원통고정부(34a)를 양쪽 끼움부재(31)의 원통부(31a) 내에 삽입시킴과 동시에, 연결소켓(34)의 원통고정부(34a)를 회전시키게 되면, 도 5 및 도 6에 도시된 바와 같이 원통부(31a)의 암나사부(31d)에 원통고정부(34a)의 수나사부(34c)가 나사결합되면서, 원통부(31a)에 대하여 원통고정부(34a)가 연결구멍(21)의 삽입방향(도 6의 화살표 b 방향)으로 이동하게 된다.Subsequently, after the connecting socket 34 is positioned between both fitting members 31, both cylindrical fixing portions 34a of the connecting socket 34 are inserted into the cylindrical portions 31a of the both fitting members 31, When the cylindrical fixing portion 34a of the connecting socket 34 is rotated, the male screw portion 34c of the cylindrical fixing portion 34a is inserted into the female screw portion 31d of the cylindrical portion 31a as shown in FIGS. 5 and 6. While screwing, the cylindrical fixing part 34a moves with respect to the cylindrical part 31a in the insertion direction (the arrow b direction of FIG. 6) of the connection hole 21. As shown in FIG.

이때, 연결소켓(34)의 양쪽 수나사부(34c)는 상호 반대가 되도록 한쪽은 오른나사, 다른 한쪽은 왼나사로 형성된 것이므로, 원통고정부(34a)의 일방향 회전조작에 의해 양쪽 암나사부(31d)를 동시에 체결할 수 있다.At this time, since both male thread portions 34c of the connecting socket 34 are formed with one right screw and the other with the left screw so as to be opposite to each other, both female screw portions 31d are rotated by one-way rotation operation of the cylindrical fixing portion 34a. Can be tightened at the same time.

이와 같이 끼움부재(31)에 대하여 원통고정부(34a)가 연결구멍(21)의 삽입방향으로 이동하게 되면, 원통고정부(34a)의 경사가압부(34d)가 제2 고정부재(33)의 내측가압경사면(33b)을 바깥측(화살표 a 방향)으로 가압하게 되고, 제2 고정부재(33)의 외측경사면(33a)은, 제1 고정부재(32)의 내측경사면(32b)을 바깥측(화살표 a 방향)으로 가압하게 되므로, 제1 고정부재(32)의 외측밀착면(32a)이 연결구멍(21)의 안둘레면(22)에 밀착되어 연결부(20)와 제1 고정부재(32)는 견고하게 고정된 상태가 된다.When the cylindrical fixing portion 34a moves in the inserting direction of the connecting hole 21 with respect to the fitting member 31 as described above, the inclined pressing portion 34d of the cylindrical fixing portion 34a moves to the inner side of the second fixing member 33. The pressure inclined surface 33b is urged to the outer side (arrow a direction), and the outer inclined surface 33a of the second fixing member 33 is the outer inclined surface 32b of the first fixing member 32 to the outside ( Arrow (a direction), the outer contact surface 32a of the first fixing member 32 is in close contact with the inner circumferential surface 22 of the connection hole 21, so that the connecting portion 20 and the first fixing member 32 ) Is firmly fixed.

이와 동시에, 제1 고정부재(32)의 내측경사면(32b)과 제2 고정부재(33)의 외측경사면(33a)에 의해서는 제1 고정부재(32)에 대하여 제2 고정부재(33)를 연결구멍(21)의 삽입방향으로 이동시키게 되므로, 제2 고정부재(33)가 끼움부재(31)의 원통부(31a)를 연결구멍(21)의 삽입방향(화살표 b 방향)으로 당기게 되고, 이로써 끼움부재(31)의 걸림턱(31b)이 연결부(20)의 끝단에 밀착되어 연결부(20)에 대하여 끼움부재(31)를 견고하게 고정할 수 있으며, 이들 사이에 설치된 제1 패킹(35)은 압착되어 더욱 확실한 수밀을 유지할 수 있게 된다.At the same time, the second fixing member 33 with respect to the first fixing member 32 is formed by the inner inclined surface 32b of the first fixing member 32 and the outer inclined surface 33a of the second fixing member 33. Since it is moved in the insertion direction of the connection hole 21, the second fixing member 33 pulls the cylindrical portion 31a of the fitting member 31 in the insertion direction (arrow b direction) of the connection hole 21, As a result, the locking jaw 31b of the fitting member 31 is in close contact with the end of the connecting portion 20, thereby firmly fixing the fitting member 31 with respect to the connecting portion 20, and the first packing 35 installed therebetween. ) Can be pressed to maintain a more reliable watertight.
