Description

Technical Field

[0001] The present application relates to the technical field of sports equipment, and in particular to a disc-type radial winding mechanism. Background Art

[0002] Disc-type radial winding mechanisms refer to mechanisms or devices used to provide resistance or tension in sports equipment. These mechanisms are designed to provide users with various forms of training. The mechanisms are usually used in conjunction with tension ropes, rods or other connectors. Users train by pulling these connectors to overcome the resistance provided by the mechanisms. The design and function of the force mechanism can vary according to different sports equipment and training needs, and is designed to provide users with a safe and effective training experience.

[0003] When using the tension mechanism, users may pull the tension line at different speeds and forces. This inconsistent use may cause the tension line to rub or twist on the pulley, causing reciprocating winding.

[0004] The traditional disc-type radial winding mechanism generally adopts an axial winding structure. Each circle of the tension wire is arranged in sequence, and the tension wire is reciprocated, which will cause the wire arrangement to be uneven and crisscrossed, resulting in poor use effect. Or, adding a wire arrangement mechanism makes the mechanism complicated and cumbersome, and increases the manufacturing and maintenance costs. Utility Model Content
