WIPO Patent Application WO/2021/246771
Kind Code:
A1
Abstract:
The objective of the present invention is to press and fix a tube while the tube is in a fitted state, thereby preventing rotation even if external force is applied and preventing water leakage, and the present invention relates to a tube press-fitting structure of a water purification line, comprising: a body provided on a water purification line; a tube fitted to the body to form the water purification line; and a fastening cap fastened and fixed to the body to prevent the tube, while coupled to the body, from being separated therefrom, wherein the body has a tube insertion part and a cap fastening part, so that the fastening cap is assembled in a state in which the tube is fitted to the tube insertion part, a pressing inclined surface is formed on the inner circumference of the fastening cap so that a locking part of the fastening cap is caught by and assembled on the cap fastening part while the pressing inclined surface presses the outer circumference of the tube, the tube insertion part has a tube insertion pipe and a tube connecting part, which has an outer circumference larger than that of the tube insertion pipe so as to be pressed onto the inner circumference of the tube, and the tube insertion pipe has tube pressing parts that protrude to press the front end portion of the tube so that the rotation of the tube is prevented as the tube is pressed by means of the pressing inclined surface of the fastening cap while the tube is in a fitted state, and thus rotation while the tube is in a fastened state is prevented and the assembled state thereof is stably maintained.
