[0026] Example 1:
[0027] This embodiment provides a bouncing mechanism for a fitness device, such as... Figures 1-3 As shown, it includes a lifting rod 1, an elastic element 5, a first mounting cylinder 2, a second mounting cylinder 3, and a limiting assembly 4.
[0028] The lifting rod 1 is fixed in the first mounting cylinder 2, which is connected to the second mounting cylinder 3 and can move up and down relative to the second mounting cylinder 3. Specifically, a limiting plate 6 is connected to the first mounting cylinder 2, and a narrowed opening is located at the top of the second mounting cylinder 3. The first mounting cylinder 2 is installed in the second mounting cylinder 3 and extends out from the opening, and is confined within the second mounting cylinder 3 by the limiting plate 6. The lifting rod 1 can be telescopically adjusted in length.
[0029] The limiting component 4 is adjustablely connected to the outside of the second mounting cylinder 3. The elastic element 5 is sleeved on the outside of the first mounting cylinder 2, with its upper end abutting against the limiting portion 21 on the outside of the first mounting cylinder 2 and its lower end abutting against the limiting component 4. The elastic element 5 can be a spring, an elastic pad of different materials, or a pneumatic structure to provide a lighter or stronger support effect. Preferably, the elastic element 5 is a spring. The limiting portion 21 can be an annular plate-shaped structure perpendicular to the axis of the first mounting cylinder 2.
[0030] In this embodiment, the jumping mechanism of the fitness device enables the lifting rod 1 to bounce up and down relative to the second mounting cylinder 3 by setting the elastic element 5. Furthermore, by making the limiting component 4 adjustablely connected to the outside of the second mounting cylinder 3, the limiting component 4 can move up and down relative to the second mounting cylinder 3, thereby adjusting the preload of the elastic element 5 to adjust the jumping force.
[0031] When the bouncing mechanism of this embodiment is used on an exercise bench, the bench surface is connected to the top of the lifting rod 1, and the support base can be indirectly connected to the bottom of the second mounting cylinder 3. The lifting rod 1 is used for adjusting the height of the bench surface, making it easy for users of different heights to adjust to a suitable height. The elastic element 5 provides the bench surface with an up-and-down bouncing function, allowing users to experience elastic support while sitting, which helps to exercise lower limb strength. Compared with existing rotating benches, the application of the bouncing mechanism in this embodiment improves the comfort of using the exercise bench and is suitable for long-term seated exercise.
[0032] In a preferred embodiment, an external thread section 31 is provided on the outer side of the second mounting cylinder 3, and an internal thread 421 is provided on the inner side of the limiting component 4. The limiting component 4 is adjustablely connected to the second mounting cylinder 3 via the thread.
[0033] In this embodiment, the vertical position of the limiting component 4 on the second mounting cylinder 3 is adjusted by rotating the limiting component 4, thereby adjusting the preload of the elastic element 5 to adjust the bouncing force. This adjustment is convenient and easy to use.
[0034] In a preferred embodiment, a connector 22 is provided on the outer side of the first mounting cylinder 2. The connector 22 is arranged around the outer periphery of the first mounting cylinder 2, and its top end is connected to the limiting part 21. The bottom end of the connector 22 extends downward. A downward-opening receiving cavity 23 is formed between the connector 22 and the outer wall of the first mounting cylinder 2, and an elastic member 5 is disposed in the receiving cavity 23. The bottom end of the connector 22 is higher than the bottom end of the first mounting cylinder 2. Preferably, the connector 22, the first mounting cylinder 2, and the limiting part 21 are an integral structure.
[0035] In this embodiment, the elastic element 5 is disposed in the receiving cavity 23 to guide the expansion and contraction deformation of the elastic element 5, making the bouncing motion more stable.
[0036] In a preferred embodiment, the limiting component 4 includes a limiting seat 41 and an adjusting sleeve 42. The limiting seat 41 is disposed on the upper side of the adjusting sleeve 42, and the limiting seat 41 and the adjusting sleeve 42 are separable.
[0037] An abutment platform 411 is provided on the inner side of the limiting seat 41 near the second mounting cylinder 3, extending to the upper side of the edge of the second mounting cylinder 3. The abutment platform 411 is positioned directly opposite the lower opening of the receiving cavity 23, and the bottom end of the elastic member 5 abuts against the abutment platform 411, confining the elastic member 5 within the closed space formed by the receiving cavity 23 and the abutment platform 411. An internal thread 421 is provided on the inner side of the adjusting sleeve 42.
[0038] In this embodiment, the vertical position of the adjusting sleeve 42 relative to the first mounting cylinder 2 is adjusted by rotating the adjusting sleeve 42, thereby adjusting the vertical position of the limiting seat 41, adjusting the height of the abutment platform 411 extending into the receiving cavity 23, and thus adjusting the restricted space of the elastic member 5.
[0039] In a preferred embodiment, an upward-opening limiting groove 412 is provided on the outer side of the abutment platform 411 of the limiting seat 41, and the insertion part 22 is movable up and down in the limiting groove 412. Both the insertion part 22 and the limiting groove 412 are annular in shape.
[0040] The bottom end of the abutment platform 411 abuts against the top end of the second mounting cylinder 3, and the bottom plate of the limiting groove 412 abuts against the top end of the adjusting sleeve 42. The two side walls of the abutment platform 411 and the limiting groove 412 are an integral structure.
[0041] In this embodiment, during the compression of the elastic element and the bouncing process, the insertion part 22 moves up and down in the limiting groove 412, further limiting the lateral movement of the first mounting cylinder 2 relative to the second mounting cylinder 3, thus ensuring the stability of the bouncing process.

[0043] In one preferred embodiment, the lifting rod 1 is a non-rotatable pneumatic rod.
[0044] In one preferred embodiment, the lifting rod 1 is a rotatable pneumatic rod.
[0045] In this embodiment, the nitrogen pump can be either a non-rotatable nitrogen pump or a rotatable nitrogen pump. When using a non-rotatable nitrogen pump, a spring can be installed at the bottom of the exercise bench to provide rebound support during twisting, offering some resistance and achieving a certain training effect. When using a rotatable nitrogen pump, the bench surface can rotate 360° without restriction, making it more entertaining.
[0046] This embodiment also provides a fitness bench, including a bench surface 7 and a bouncing mechanism of the fitness device, with the bench surface 7 mounted on the top of the lifting rod 1.
[0047] This embodiment also provides a fitness chair, including a seat and a bouncing mechanism of the fitness device, with the seat mounted on the top of the lifting rod 1.
[0048] In this embodiment, the bench or chair surface serves as the user's sitting or lying surface and features an ergonomic design to ensure user comfort during extended use. By applying a bouncing mechanism to the exercise bench or chair, it enables up-and-down bouncing motions, enhancing the fitness effect and improving user comfort compared to traditional swivel benches, making it suitable for prolonged seated exercise.
