REPULSION OPERATION MECHANISM

WIPO Patent Application WO/2016/058548

A1

A repulsion operation mechanism comprises a movable iron core (90) in transmission connection with a switch pull rod (19), and a sealing cavity (7) through which the movable iron core (90) moves in a reciprocating manner for opening and closing purposes. When moving to two ends of the sealing cavity (7), the movable iron core (90) is respectively at a closing position and an opening position. The movable iron core (90) is a moving plate that divides the sealing cavity (7) into two portions. Through holes (610) that connect the inside and the outside of the sealing cavity (7) and are used for feeding or discharging buffering media are formed at an opening position and a closing position or at positions close to the opening position and the closing position on a circumferential wall of the sealing cavity (7). By means of the repulsion operation mechanism, quick buffering on the opening and closing movement of the switch pull rod can be effectively realized, and the buffering effect is good.
