본 발명은 스크링쿨러 헤드와 급수관을 연결하는 장치에 관한 것으로서, 보다 상세하게는 플라스틱 사출 성형 방법으로 엘보를 제조하여도 누수되는 것을 방지할 수 있는 스프링 쿨러 헤드용 연결관 승강장치에 관한 것이다.
The present invention relates to a device for connecting a scrincooler head and a water supply pipe, and more particularly, to a sprinkler head connector pipe lifting device capable of preventing leakage even when the elbow is manufactured by a plastic injection molding method.

대한민국 실용신안등록 제20-0448099호(2010년 3월 9일, 등록)에 "스크링쿨러 헤드용 연결관 승강장치"가 소개되어 있다.Republic of Korea Utility Model Registration No. 20-0448099 (registered on March 9, 2010) is introduced "connector elevating device for the screw cooler head".

상기 스크링쿨러 헤드용 연결관 승강장치는 건물 내부의 천장에 설치되며 급수관으로부터 공급되는 소화수를 살수시키는 헤드가 고정되는 스프링쿨러 헤드용 연결관 승강장치에 있어서, 급수관에 연통되도록 이음연결되고, 외측면에 제1,2나사부가 형성되는 엘보우와, 엘보우에 상하방향으로 이동가능하게 결합되고, 엘보우의 내측면에 밀착되어 누수되는 것을 방지하도록 외측면에 패킹이 장착되며, 외측면에 나사부가 형성되는 이동관과, 엘보우의 제2나사부와 이와 대응되는 제1나사공의 상호 나사결합으로 이동관을 엘보우에 고정시키고, 이동관의 나사부와 이와 대응되는 제2나사공의 상호 나사결합으로 엘보우로부터 이동관 이탈되는 것을 방지하는 체결너트를 포함하여, 엘보우에 이동관을 승강가능하게 결합시키고 엘보우 및 이동관에 체결너트를 나사결합시킨 후, 엘보우에 대해 이동관의 회전방향에 따라 이동관의 상하방향으로의 높낮이를 조정할 수 있다.The sprinkler head connection pipe lifting device is installed on the ceiling inside the building and the sprinkler head connection pipe lifting device is fixed to the head to spray the digestion water supplied from the water supply pipe, the joint is connected to the water supply pipe, Elbows having first and second threaded portions formed on the side surfaces are coupled to the elbows so as to be movable upward and downward, and the packing is mounted on the outer side to prevent leakage by being in close contact with the inner side of the elbow, and the threaded portion is formed on the outer side. The movable pipe is secured to the elbow by mutual screwing of the second screw portion of the elbow and the corresponding first screw hole, and the movable tube is separated from the elbow by mutual screwing of the screw portion of the movable tube and the corresponding second screw hole. Including a fastening nut to prevent the coupling, the movable pipe to the elbow to be lifted and coupled to the elbow and the mobile pipe After screwing the agent, depending on the rotational direction of Lee Dong - kwan for the elbow it is possible to adjust the height of the top-bottom direction of Lee Dong - kwan.

그러나, 상기 스크링쿨러 헤드용 연결관 승강장치는 엘보우를 플라스틱 사출할 경우, 엘보우의 성형오차로 인하여, 엘보우와 이동관의 연결하는 부분에서 패킹이 제구실을 하지 못하여 누수가 발생하고, 스크링쿨러 헤드가 체결되는 이동관의 하단 외경이 매우 크게 제작되고, 이동관의 하단 외경에 따라 체결 너트가 많이 커져야 하는 단점이 있었다.
However, when the elbow is plastic-injected, the elevating pipe elevating device for the screw cooler head is leaked due to the molding error of the elbow, which causes the packing to fail in the connection part of the elbow and the moving tube, causing a leak. The bottom outer diameter of the moving tube to be fastened is made very large, there was a disadvantage that the fastening nut has to be large according to the bottom outer diameter of the moving tube.
