Description

Technical Field

[0001] This invention relates to the field of rowing technology, and in particular to a multi-wheel structure pulley return assembly. Background Technology

[0002] Current rowing simulation technologies typically involve connecting elastic ropes to the ends of simulated oars. After fixing the elastic ropes, the elastic force of the ropes is used to simulate the rowing force of the oars. However, in the aforementioned existing technologies, the elasticity of the elastic ropes increases with the length under force, while the elastic tension decreases when the length under force decreases. In actual rowing, the resistance of the long-pole double oars to the water surface does not change significantly. Therefore, the simulation of the force exerted by the elastic tension during rowing cannot be fully represented. Summary of the Invention

[0003] One of the objectives of this invention is to provide a multi-wheel structure pulley return assembly, wherein the return assembly is specifically provided with a pulley assembly, which includes multiple pulleys. The pulley assembly and multiple fixed pulleys are connected by a transmission rope. The pulleys are designed to reduce the frictional resistance experienced by the return assembly, thereby making the simulated force results of the simulated oar more accurate.

[0004] Another objective of this invention is to provide a multi-wheel structure pulley return assembly. The return assembly is a pulley assembly with multiple pulleys, wherein a rigid rope is connected to two pulleys, and an elastic transmission rope is connected to one pulley.
