HYDRAULIC GRAVITY-TYPE CLOCKED FLIP-FLOP

WIPO Patent Application WO/2018/103351

A1

A hydraulic gravity-type clocked flip-flop, comprising a magnetic snap ring (3), a vibrating ring (4), a shell (6), a triggering spring (8), a triggering ring (9), a magnetically conductive ring (10), a gravity stopper (14) and an impact ring (16); the shell (6) has a liquid medium inside, the gravity stopper (14) moves from the upper end of the shell (6) to the lower end; when a timer is subjected to vibration, the magnetic force between the vibrating ring (4) and a first magnetic ring (5) decreases during movement, the vibrating ring (4) collides with the lower side of the magnetic snap ring (3) by means of the impact ring (16), the magnetic force exerted on the gravity stopper (14) decreases, the gravity stopper (14) starts moving downward, and timing is started. When the gravity stopper (14) moves close to a bottom plate (15), the triggering ring (9) is driven to move, the triggering ring (9) collides with the magnetically conductive ring (10), and the impact force produced therefrom can trigger an external device. As the gravity stopper (14) is lubricated and isolated from air by the hydraulic oil, the contact wall surface between the gravity stopper (14) and the shell (6) would not be oxidized, such that the timer has a longer service life; as no electricity is involved, the present invention has a wide application scope and has better usage effect.
