[0002] Among the strength training equipment available on the market, most are traditional heavy-duty machines that are difficult to fit in small homes. Currently, lightweight strength training equipment has also emerged. For example, some strength training equipment uses dual motors on both sides to pull the training rope connected to the resistance device through the tension component to achieve the purpose of exercise. It is suitable for ordinary families, but the structure of this type of strength training equipment is relatively complex. The friction components therein will generate noise and cause large losses during use. It cannot be folded and stored, and occupies a large space. Therefore, a new folding damping fitness device with 180-degree folding function and damping function is provided.

[0003] For example, Chinese patent number CN219462424U provides a flat-plate intelligent strength trainer, comprising a flat plate portion, the bottom surface of which serves as a first support surface, a motor compartment connected to a first side of the flat plate portion, a top surface of which protrudes relative to the top surface of the flat plate portion, and an outer side surface of which serves as a second support surface. When the trainer is in use, the first support surface contacts the ground, and when the trainer is in storage, the second support surface contacts the ground. This patent allows for vertical storage with the second support surface in contact with the ground, but the second support surface houses components such as a motor, which is heavy. If the upper portion of the trainer is accidentally hit and is not against a wall, it is still prone to tipping over. Furthermore, the trainer cannot be folded for storage, occupying a large amount of space. Utility Model Content

The shells 1 are hinged to the damping rotating shaft sleeves 23 through their respective rotating shaft sockets 11. A rotation amplitude limiting structure for limiting the rotation amplitude of the shell 1 is provided between the outer side of each shell 1 near one end of the rotating shaft socket 11 and the inner side of the connecting seat 21.

[0024] In specific implementation, the angle between the two shells 1 and the rotating member 2 can be adjusted within the range of 0 to 180 degrees through the rotation amplitude limiting structure, and each shell 1 can be folded downward relative to the rotating member 2, thereby realizing the folding of the two shells 1 together.

[0026] Furthermore, the rotation amplitude limiting structure may include a limiting groove 24 and a limiting protrusion 12.
