Automatic reset force transmission mechanism

Abstract

The present invention discloses an automatic reset force transmission mechanism. It comprises a base and a steel wire rope. A rotating arm and a rocker arm are movably connected to the base. The rotating arm and rocker arm are coupled to the base via bolts. A reset spring is mounted on the rocker arm. The rocker arm is also connected to an actuating arm. One end of the steel wire rope is connected to the rotating arm, and the other end is connected to a power unit, enabling the rotating arm to achieve circular motion. The torsion arm is connected to the base via a rotating shaft. This mechanism achieves the conversion from linear motion to circular motion. During actuation, the mechanism converts the tension of the steel wire rope into torsion, causing the target to rotate a certain angle before completing the actuation. After actuation is complete, the mechanism automatically resets under the action of the reset spring.
