Angle self-adjusting rope retractor:

This device is an efficient and low-friction rope transmission steering mechanism, specially designed for scenarios that require changing the direction of rope traction. It is suitable for systems such as lifting, towing, and high-altitude operations, and is particularly suitable for working conditions that require multi-directional variable loads or precise control of the rope. The core innovation lies in the unique combination of the three-degree-of-freedom rotating structure and the eccentric roller assembly, which can maintain the optimal contact angle when the rope tension direction changes dynamically, significantly reducing friction loss and prolonging the service life of the rope. The load capacity of this device depends on the bearings inside. The style shown in Figure 2 can bear a load of 20Kg, and the matching steel wire rope has a diameter of 3mm.

Three-degree-of-freedom rotating structure: The device adopts a design with three orthogonal rotating axes, allowing the roller assembly to freely adjust its direction in space, ensuring that the rope can automatically align when subjected to any angle of force, avoiding stress concentration caused by hard bending.

Eccentric roller assembly design: The central roller adopts an asymmetric size layout, forming an eccentric slot structure. When the rope passes through the rollers, the eccentric effect will dynamically adjust the contact surface, making the rope always adhere to the roller's curved surface, reducing sliding friction.
