Description

Technical Field

[0001] The utility model relates to the technical field of sports rehabilitation equipment, in particular to a joint angle limiting structure of a training device. Background Art

[0002] The knee joint is a part that is easily injured. When the knee joint is severely traumatized and undergoes surgery, it takes a long time to recover. During the recovery process, the injured person needs to train the knee joint to gradually restore the function of the knee joint. Now there is a need for a device that can train the force strength of the knee joint to help the injured person safely perform training movements to restore the function of the knee joint.

[0003] At present, most of the knee joint exercise rehabilitation equipment on the market are imported products with high prices. Although the fitness machines in the current domestic knee joint training equipment have knee joint training functions, their design and use are not targeted at patients undergoing rehabilitation training. The knee joint training equipment in the fitness equipment has many problems such as inconvenient adjustment and imperfect joint angle limiting function. When using fitness equipment for knee joint muscle strength training, there is no angle limit on the trainer. If the user is exhausted during use, it will cause safety hazards to the knee joint, causing secondary damage to the user's joint. In order to solve the above problems, a trainer joint angle limiting structure is proposed to solve the above problems. Utility Model Content
