Adjustable Connecting Rod With Continuous Yoke Alignment

The patent transitions from a static threaded rod adjustment mechanism to a dynamic system where the intermediate part can rotate continuously about the pivot axis. This rotation enables the helical link to translate the yoke continuously along the pivot axis, providing smooth length adjustment without discrete half-turn increments, thereby improving alignment ease while maintaining adaptability.

The patent introduces a rotational dimension by allowing the intermediate part to rotate about the pivot axis. This rotational movement is converted by the helical link into linear translation of the yoke, adding a dimensional transformation that enables continuous adjustment. The pivot link maintains the angular position while the helical link provides continuous linear displacement, resolving the contradiction between adjustability and alignment ease.

The patent implements continuous useful action by allowing the intermediate part to rotate continuously about the pivot axis, which continuously translates the yoke along the pivot axis through the helical link. This eliminates the need for discrete half-turn increments and misalignment operations, providing smooth, continuous length adjustment that reduces adjustment time while maintaining full adaptability.

The intermediate part acts as an intermediary that converts rotational motion about the pivot axis into linear translation of the yoke through the helical link. This intermediary mechanism eliminates the need for direct threaded rod rotation and misalignment operations, providing continuous adjustment that reduces time loss while maintaining adaptability.

The patent segments the adjustment mechanism into distinct functional components: the intermediate part for rotation, the helical link for translation, and the pivot link for maintaining angular position. This segmentation allows each component to perform its specific function with simple geometry, avoiding the need for complex continuously adjustable connecting rods while achieving continuous adjustment capability.

The intermediate part serves as a simple intermediary component that enables continuous adjustment through rotation about the pivot axis. Combined with the helical link and pivot link, this simple intermediary mechanism achieves continuous adjustment without the complex structure of existing continuously adjustable connecting rods, reducing manufacturing complexity and cost.

The pivot link acts as an intermediary that maintains the angular position of the yoke about the pivot axis during the translation motion. While the helical link translates the yoke continuously along the pivot axis for length adjustment, the pivot link ensures the angular position remains constant, thereby achieving continuous adjustment without compromising angular position precision.

The system dynamically maintains the angular position through the pivot link while allowing continuous translation along the pivot axis. The pivot link constrains rotational movement about the pivot axis, ensuring angular precision is maintained during the dynamic translation process, thus resolving the contradiction between continuous adjustment and angular position precision.
