LOCKING-UNLOCKING STRUCTURE FOR STOPPING LIFTING BODY, WHICH IS LIFTED AND FALLEN THROUGH REPETITION OF PUSHING ACTIONS, IN LIFTING STATE AND FOR RELEASING STOPPING STATE OF LIFTING BODY

摘要

A locking-unlocking structure repeatedly performs stopping of lifting of a lifting body and falling of the lifting body by releasing the stopping of the lifting body as pushing actions are only repeated when a filter cartridge to be replaced or various articles (lifting body), which requires lifting (including falling), are lifted through repeatedly pushing actions in a water purification system. An actuation unit constituting a locking-unlocking unit is mounted in a lifting body, and an actuation guide unit coupled to the actuation unit is mounted in a fixing body when the lifting body is lifted and falls in the fixing body. As the actuation unit circulates along a lifting line and a falling line of the actuation guide unit, the stopping of lifting of the lifting body is performed through a pushing action and the falling of the lifting body is performed by releasing the stopping through re-pushing.
