Product Name : Pipe connecting device (파이프 접속 장치)
Technical Code : 107076338
The present invention relates to a pipe connecting device for connecting a plurality of pipes and, more particularly, to a pipe connecting device that can not only connect individual pipes but can also improve the reliability of pipe connecting portions, through a relatively simple structure. The pipe connecting device is configured of: a cylindrical first connecting member provided with a pipe having a catching ledge on a connecting terminal end portion thereof, a spring seating portion in which a circular plate spring is seated, a pipe through-hole through which the pipe passes, and a screw recess on the inside thereof; and a second connecting member provided with an o-ring seating portion in which an o-ring is seated at the side at which the pipe is coupled, and a through-portion having a screw thread formed on the outside thereof and having the same inner diameter as the pipe. Thus, the pipe connecting device does not cause deformation of pipes and even allows an inexperienced layperson to easily connect each pipe and the reliability of pipe connecting portions to be improved by virtue of a relatively simple structure. Particularly, for pipes configured of thin plates made of stainless steel or copper material that have relatively little difference between the inner and outer diameters thereof, the effects are provided in that deformation caused by pipe connecting structures is fundamentally prevented, the speed and the quantity of fluid flowing through pipes can be uniformly maintained, and pipes can be easily connected on-site without separate tools and without the need to secure a workspace for connecting the pipes.
