PIPE JOINT HAVING WATERTIGHT STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2014/092371
Kind Code:
A1
Abstract:
The present invention relates to a pipe joint having a watertight structure. The pipe joint includes: a coupling cap in which a hollow is formed so as to allow a pipe to pass therethrough; a grip means disposed so as to contact the inner surface of the coupling cap and passing the pipe; a hollow body, one end of which is coupled to the inner surface of the coupling cap in a state facing one end of the grip means; and an end coupling means coupled to the inner surface of the body so as to allow one end of the pipe to be inserted. The end coupling means includes an internal diameter insertion part coupled to the inner circumferential surface of the pipe using an internal o-ring that is disposed therebetween, an external diameter insertion part coupled to the outer circumferential surface of the pipe using an external o-ring that is disposed therebetween, and a connection part connecting an end of the internal diameter insertion part and an end of the external diameter insertion part to each other. The internal diameter insertion part has a length longer than that of the external diameter insertion part. An internal o-ring groove part, in which the internal o-ring is disposed, is formed in the internal diameter insertion part, and an external o-ring groove part, in which the external o-ring is disposed, is formed in the external diameter insertion part. Therefore, the pipe joint may completely seal the internal and external portions of the pipe so as to block perfusate from being introduced to the end of the pipe, thereby preventing the cut end of the pipe from being corroded and firmly fixing the pipe.
