ROTARY GRAVITY-TYPE CLOCKED FLIP-FLOP

WIPO Patent Application WO/2018/103350

A1

A rotary gravity-type clocked flip-flop, comprising a vibrating spring (3), a top cover (4), a vibrating ring (5), a shell (6), a bottom plate (7), a spiral spring (8), a triggering post (9) and a gravity stopper (11); the shell (6) has hydraulic oil inside, the gravity stopper (11) has a hydraulic hole (17), the hydraulic oil flows through the hydraulic hole (17) of the gravity stopper (11) when the gravity stopper (11) moves from top to bottom, such that the gravity stopper (11) rotates; when the gravity stopper (11) comes close to the bottom plate (7), a driving shift block (18) will contact and collide with a driven shift block (14), prompting the triggering post (9) to start rotating so as to trigger an external mechanism. The vibrating ring (5) will vertically reciprocate under the effect of an external force when a timer is subjected to vibration, such that the gravity stopper (11) starts moving downward, and timing is started; as the gravity stopper (11) is lubricated and isolated from air by the hydraulic oil, the gravity stopper (11) and the shell (6) would not be oxidized and the accuracy thereof would not be changed, 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.
