Description

Technical Field

[0002] Rotation means that an object moves in a circle around a point or an axis. With the development of society, rotation control mechanisms are widely used in industrial production.

[0003] Prior art includes a utility model with publication number CN211841222U, which discloses a rotation control mechanism including a transmission cylinder, a connecting arm and a ratchet arranged on a rotating shaft, and also includes a toggle connector; one end of the connecting arm is sleeved on the rotating shaft, and the other end is hinged to the piston rod of the transmission cylinder; the toggle connector is rotatably arranged on the connecting arm, and the edge of the toggle connector abuts against the ratchet. The rotation control mechanism disclosed in the utility model is achieved by sleeved one end of the connecting arm on the rotating shaft and hinged to the piston rod of the transmission cylinder at the other end. When the piston rod of the transmission cylinder is extended, the rotating shaft is driven to rotate, so that the angle of the ratchet starts to rotate. At this time, the toggle connector arranged on the connecting arm pushes the ratchet to rotate on the outside of the ratchet. When the ratchet rotates into place, the connecting arm pulls the toggle connector to disengage from the ratchet and clamp it on the next ratchet tooth of the ratchet. Through this arrangement, the rotation angle of the ratchet can be accurately controlled.

[0004] Most existing rotation control mechanisms have complex structures, and the transmission components are exposed to the outside, which is easy to contact with other objects, causing wear and failure, shortening the service life of the equipment. In addition, the equipment uses cylinders for transmission, which can easily cause the equipment to rotate unsmoothly, affecting its rotation control operation and not conducive to the normal use of the equipment. Improvements are needed in this regard. Utility Model Content
