As described above, according to the present invention,
First, the overall size and external shape is similar to the conventional pipe connector, but protruding by bending a part of the body in the process of manufacturing without providing a separate member for supporting the end portion of each pipe (mounted support ring) Forming so as to simplify the manufacturing process to improve the manufacturing efficiency can significantly reduce the manufacturing cost.
Secondly, unlike the conventional pipe connector, a separate member is not fixedly mounted to the body, and the support protrusion ring supporting the end of each pipe is integrally formed with the body, so that the support protrusion ring may be subjected to excessive load or strong impact. Since it is not detached from the body, safety accident can be prevented in advance.
Third, while the structure is simplified to increase the production efficiency by simplifying the manufacturing process, the overall size and external shape is formed similar to the conventional pipe connector, can be used in combination with the conventional pipe connector, the user's convenience is maximized, There is an advantage in that the existing pipe joints can be recycled.
Fourthly, in forming the pipe connector, a plurality of first fitting protrusions and first fitting grooves are alternately formed at one end of the base plate, respectively, and the second fitting grooves and the first fitting protrusions at which the first fitting protrusions are fitted. A plurality of second fitting protrusions alternately fitted to the fitting grooves are formed, respectively, and the first fitting protrusion is fitted into the second fitting groove while the base plate is bent, and the second fitting protrusion is fitted to the first fitting groove. Since both ends of the base plate can be fastened to each other to form the pipe connector by fitting, it is possible to more easily fasten both ends of the base plate as compared to the welding and fastening method, thereby further reducing the manufacturing cost. have.
Fifth, when it is necessary to form a fastening groove for mutual fastening with each of the pipes to be connected to both sides of the pipe connector, in the process of cutting the base plate for bending the pipe connector to be cut together Therefore, compared to the case of cutting the fastening groove in the state bent in a cylindrical shape, there is an advantage that the cutting process is easier and can be processed into a precise groove shape.
