In general, the pipe connecting device is mainly used as a means for connecting and fixing the pipe and the pipe while maintaining the airtightness of the pipe, and its structural form is more straight, elbow, T-shaped, cross-shaped, etc. Has various forms.

Conventional pipe connection devices require separate fixing means such as welding pipe connections or screw connections and snap rings to improve airtightness and connectivity, making pipe connection work difficult and increasing the assembly process. This increases the construction cost.

In addition, the general stainless steel pipes for transfer that are used in such conventional pipe connection devices are thin, so it is difficult to form screws as well as welding at the construction site. There is an inconvenience that a separate process such as pipe expansion or expansion has to be added. .
In order to solve such problems, various pipe connecting devices have been developed.

Japanese Published Patent Publication No. 10-2009-0039630 was disclosed regarding the pipe connecting device.
As shown in FIG. 1, a pipe connecting device (110) is installed at a position where two pipes (1) and (2) are connected to each other as shown in FIG. ; Inserted and connected separately to both ends of the pipe connection port (110) in a state of being interposed between the pipe connection port (110) and the pipes (1) and (2), and spaced apart along the outer peripheral surface; A jaw holder (120) in which a number of jaw mounting holes (121) are formed, and is rotatably mounted in the jaw mounting hole (121) to the inner wall (110a) of the pipe connection port (110). A jaw (130) that presses and fixes the pipes (1) and (2) that are pressed and inserted into the jaw holder (120); the pipe connection port (so that the jaw (130) can be elastically supported 110 It includes an elastic member installed in the interior (140). At this time, a backup ring (150), a spring support ring (160), and a seal ring (170) are installed in the pipe connection port (110).

However, since the pipe rivet must be formed with an inclined part in the main body, and the pipe connecting device has to be manufactured with complicated jaw holders and jaws separately, the production time and assembly time are different. There are other problems, such as increased production costs.

In order to solve such problems, domestic registered patent publication No. 10-0984839 was developed.
As shown in FIGS. 2 and 3, the pipe connection of the Japanese registered patent publication No. 10-0984839 is a pipe in which a round home portion (111) and an inclined portion (112) are formed along an inner peripheral wall. 10), a pair of main bodies (110) for receiving, and a pair of main bodies (110) adapted to move along the inclined portion (112), and stopping members (120) for stopping the movement of the pipe (10). ), A first elastic member (130) for elastically supporting the stopper member (120) in the radial direction, a second elastic member (140) for elastically supporting the stopper member (120) in the axial direction, and a pair of main bodies ( 110) includes a lid member (150) provided in the mouth (113) to prevent foreign substances from entering.

However, after inserting the stopper member and the first and second elastic members into the main body, the pipe connector is narrowed by applying pressure to prevent them from being removed. There is a problem in that scratches and the like are generated on the appearance, and the internal elastic member is melted by heat, so that it is impossible to perform a welding operation for connecting pipes, and the application site is limited.
