This cumbersome and delayed process requires the use of threading tools (such as dies) and rotary tools (pipe wrenches, etc.) at the end of the pipe in the field, making it difficult to carry and carry construction equipment, as well as pipe wrenches in turning pipes or fittings. There is a closed end where the surface of the pipe or fitting is damaged by the contact and slip of the jaw, etc., resulting in corrosion. The latter does not have the closed end in the above-described screwing type, but the pipe and the fitting are simply adhered by packing. As the connection part is easily relaxed and separated, the use of the pipe is restricted in pressure or external force. However there were.

따라서 본 출원인은 이러한 제반 폐단을 해소하기 위하여 삽입구에 연결할 관을 삽입하고, 삽입구 단부를 조여서 축경시키는 것만으로써 접속이 간편하면서도 견고하게 체결되도록 한 관이음쇠를 1986년 실용신안등록출원제 71호, 동제 72호, 및 동제 73호로써 안출한 바있다.Accordingly, the present applicant has inserted a tube to be connected to the insertion hole in order to solve such a closed end, and tightened the tube fitting to make the connection simple and secure by simply tightening the end of the insertion hole. No. 72 and No. 73 were issued.
