ONE-TOUCH APPARATUS FOR OPERATING A WATER GATE, CAPABLE OF EASILY GOING DOWN A WATER GATE USING THE SELF WEIGHT OF A WATER GATE BY OPTIONALLY SEPARATING A WORM WHEEL AND A WORM

摘要

PURPOSE: A one-touch apparatus for a water gate is provided to lift down a water gate easily by making a water gate descend by the self-weight of a water gate. CONSTITUTION: The one-touch apparatus for a water gate(1) is composed by coupling a bearing housing(5) with a built-in stem nut to be supported to a bearing, a gear box(6), an indicator box(7) and a stem cover(8) on the upper part of a stand(2) in order, coupling a sleeve clutched with the stem nut to the inside of a gear box(6) by a shaft, coupling a worm gear to the sleeve and engaging with a worm coupled to the gear box(6) by a shaft; and rotated by a handle(13) coupled to a handle shaft exposed to the outside, then screwed on the stem nut to lift up and down a water gate shaft. The worm is coupled to a gear box(6) by a shaft, inserted to a worm installation space of a movable shaft and coupled to a handle shaft coupled to a movable shaft eccentrically to separate a worm wheel and a worm when a movable shaft is operated; the movable shaft installed to the gear box(6) is coupled with an operating lever(18) and provided with a hanging hole; and a stopper is installed on a gear box(6) to be bounded by a spring and provided with a fixed pin of the stopper coupled to the hanging hole.
