Abstract

A connecting tube structure comprises a connecting tube, screw nuts, check valves, and a rotary water-sealing device wherein the connecting tube has a stop plate at one end to mount to a grooved seat of the rotary-sealing device and a cavity at the other end for the accommodation of one check valve with a movable plug supported by a spring to shut off water discharge from the faucet and prevent the return of dirty water. The rotary water-sealing device, having watertight O-rings adapted to the upper section and a V-shaped expanding side wall extending at the lower section, is sealed to the bottom and internal surface of the shower head and enclosed by the screw nut secured to the shower head, providing high-and-lower pressure water-sealing benefit as well as rotation in 360 degrees to prevent the connecting tube from getting twisted up and hindering the smooth transport of water supply.
