Abstract

PURPOSE: Cum plate is rotatingly moved by directly connected associated shaft of the open/close equipment, thereby to increase the cum movement, providing an accurate detection.
CONSTITUTION: When the driving device is turned on to wind up the water gate, the water gate rises upward, and associated shaft 3 correlatingly rotates. This rotates the sleeve 12 engaged with slide shafts 4,5 and the sleeve 12 moves along screw thread of the screw rod 7. When the water gate has reached the top end, the cum plate 14 combines with the detection piece 28 to rotate the lever 24. This actuates the limit switch 22 which generates signal to stop the water gate. Thus, the cum plate is rotatingly moved by the directly connected associated shaft of open/ close device and combination of rotational and direct movement, resulting in increased cum movement to provide an accurate detection.
