ABSTRACT:
A touch button controlled water stop mainly consists of an outer sleeve, a shaft rod, an upper toothed ring, a lower toothed ring, a spring guide bush, two springs, and a plunger; the shaft rod extending through a spring, a washer, a packing sheet, and a bushing ring and subsequently passing through the hollow cylindrical outer sleeve having a shaft support formed therein, the upper toothed ring, the lower toothed ring, the spring guide bush, and another spring and ending with the plunger secured thereon by a screw. The top end of the shaft rod can be linked with a touch button actuating means and the outer sleeve can be accommodated in a rear connector so that depressing the touch button will move the upper toothed ring to engage with the lower toothed ring. Further, raised blocks formed on the outer sleeve's inner wall confines the slide motion of the upper toothed ring and the lower toothed ring in such a way that the shaft rod will in turn dwell at two positions for each depressing. And thus the shaft rod can drive a plunger to open and close a water inlet, controlling water flow in a pipe.
