The invention discloses a joint quick water stop structure, which comprises a sliding sleeve, a valve shell, two water stop rings, a ball valve, a connecting piece and a shift rod.The sliding sleeve has a sliding sleeve hole and a connecting hole.The valve shell is pierced with a sliding sleeve, and has a first-class perforation, a first and second locking sections, and a cutting groove.Each water stop ring is contained in the class perforation and has a perforation connected with the class perforation.The ball valve is arranged between the water stop rings, has a valve hole and a shift rod groove.The connector series valve shell is provided with a connector hole and a first lock part.The paddle is connected by a sliding sleeve to drive the ball valve to rotate, so that the valve perforation can be selectively misplaced or communicated with the perforation of each water stop ring.By the composition of the above components, the utility model is connected between the water pipe and the outlet head (or sprinkler), providing remote water control and avoiding the overflow of residual water in the water pipe.本發明係揭露一種接頭快速止水結構，包含一滑套、一閥外殼、兩止水環、一球閥、一連接件、及一撥桿。該滑套具有一滑套穿孔及一連接孔。該閥外殼穿伸滑套穿孔，具有一階級穿孔、一第一、二鎖接段、以及一剖槽。各止水環係容設於階級穿孔內，具有一與階級穿孔連通之穿孔。該球閥係容置於各止水環之間，具有閥穿孔以及一撥桿槽。該連接件係串接閥外殼具有一連接件穿孔及一第一鎖部。該撥桿係穿伸連接孔、剖槽及撥桿槽，並受滑套連動以驅動球閥自轉，使閥穿孔選擇性的與各止水環之穿孔錯位或連通。藉由上述構件之組成，連接於水管與出水頭(或花灑)之間，提供遠端控水且可避免水管中的殘水溢出。
