Patent attributes
A tube connector has a main body, a restricting element, and a sealing ring. The main body has a mounting segment extending outwardly and transversely to form an inner annular space to accommodate the restricting element and the sealing ring. When the tube body is inserted, the tube body will be engaged and positioned by teeth of the restricting element. The sealing ring and the restricting element abut each other to maintain the sealing from the sealing ring. The changes of the pressure from the fluid transporting in the tube body will move the tube body and the main body relatively to and fro, and thus the abutting force against the sealing ring will increase or decrease accordingly, which maintains the elasticity of the sealing ring to maintain the sealing after a long time of use, thereby avoiding elastic fatigue and prolonging the lifespan.
