Description

Technical Field

[0001] The utility model belongs to the technical field of fitness equipment, in particular to a roller type upper limb traction device. Background Art

[0002] An upper limb traction device is a type of fitness equipment used for rehabilitation. The common roller-type upper limb traction device is characterized by a roller and a traction rope wrapped around the surface of the roller. When the patient is training, he needs to hold the two ends of the traction rope with both hands. When one arm moves downward, the other arm is pulled up by the traction rope. This cycle is repeated to achieve the effect of rehabilitation training for the upper limbs.

[0003] During the use of the current roller-type upper limb traction device, since the rollers are mostly installed directly through bearings, the rotation of the rollers is relatively smooth. However, this means that when the patient pulls down the traction rope, the only resistance they need to overcome is the force of pulling up the other arm. During the training process, as the upper limb strength recovers, the training effect of the traction device will gradually decrease, making it difficult to achieve a long and effective training effect.

[0004] In summary, the utility model provides a roller type upper limb traction device to solve the above problems. Utility Model Content
