Terms such as "comprising" or "including" mean that the element or object preceding the word covers the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0023] Example 1:

[0024] like Figures 1 to 4 As shown, this embodiment provides a cardiopulmonary rehabilitation chest expansion auxiliary training device, including a device body 10 and a straight rod 101 fixed on the device body 10. The outer edge of the straight rod 101 is rotatably connected to a first rotating rod 11. One end of the first rotating rod 11 is fixedly connected to the end of a second rotating rod 112. The other end of the first rotating rod 11 is provided with a damping mechanism. The damping mechanism is used to change the damping when the first rotating rod 11 rotates around the straight rod 101. The device body 10 is also provided with a support mechanism for supporting the back. When the damping of the damping mechanism changes, the support area of ​​the support mechanism on the back can be changed simultaneously.

[0025] The present scheme solves the problems that the traditional chest expansion auxiliary training device cannot flexibly adjust the training damping and lacks effective support for the back of the user during high-damping training. In addition to the components described above, the device body 10 is also equipped with a stable base for supporting the entire device to ensure stability during use. The working principle is as follows: the user performs chest expansion movement by operating the second rotating rod 112 connected to the first rotating rod 11, and the damping mechanism can flexibly change the damping of the rotation of the first rotating rod 11 around the straight rod 101 by different connection states of the sliding block 16 and the first rotating rod 11, to meet the needs of different rehabilitation stages of the user for training intensity. At the same time, the support mechanism is associated with the damping mechanism, and when the damping increases, the support mechanism will increase the support area for the back of the user, providing strong back support for the user. In actual application, not only the training effect is improved, but also the comfort and safety during training are greatly improved. In the alternative aspect, the damping mechanism can consider using different types of elastic element combinations, such as rubber elastic body and spring 141, to achieve damping adjustment; the backrest 13 of the support mechanism can also be designed as foldable to adapt to different use scenarios and storage needs.

[0026] In this embodiment, the damping mechanism includes a slot provided on the first rotating rod 11, the inner wall of the slot is fixed with a clamping strip 111, the device body 10 is slidingly connected with a sliding plate 14 near the back, the sliding plate 14 is fixed with a plurality of springs 141, the springs 141 are fixed with sliding blocks 16, and the sliding blocks 16 are fixed with guide rails 161 which can slide in the gap between the clamping strip 111 and the slot along the length direction of the first rotating rod 11.

[0027] In the slot of the first rotating rod 11, a smooth lining can be provided at the bottom of the slot to reduce the additional friction when the sliding block 16 slides. The sliding track of the sliding plate 14 on the back of the device body 10 can adopt a dovetail groove structure to ensure the stability of the sliding plate 14. The working principle is that the user pushes the sliding plate 14 according to the training needs, so that the sliding block 16 connected by the spring 141 on the sliding plate 14 slides along the gap between the clamping strip 111 and the slot in the length direction of the first rotating rod 11 under the action of the guide rail 161. As more sliding blocks 16 are inserted into the slot, the spring 141 needs to overcome the elastic force, and the rotation damping of the first rotating rod 11 increases. The alternative is to replace the clamping strip 111 with a sawtooth structure, and the end of the sliding block 16 is designed to match the tooth shape, so as to realize the change of damping by the meshing of different teeth.

[0028] In this embodiment, the support mechanism includes a backrest 13 slidingly connected to the back of the device body 10, and a connecting rod fixedly connected to the backrest 13 and the sliding plate 14 at both ends is arranged between the backrest 13 and the sliding plate 14; when the backrest 13 approaches the back, it can push the sliding block 16 into the slot, so as to increase the rotation damping of the first rotating rod 11.

[0029] In the device body 10 near the back side, the connecting rod between the slide plate 14 and the backrest 13 can be a telescopic rod to adapt to the body size difference of different users. The backrest 13 sliding rail can be provided with a limit block to prevent the backrest 13 from sliding excessively. When working, when the backrest 13 is close to the back due to the force generated by the user's chest expansion action, the connecting rod drives the slide plate 14, and then pushes the sliding block 16 into the slot to increase the rotation damping of the first rotating rod 11. In actual use, it provides reliable back 13 support for users during high-damping training, ensuring safe and comfortable training. Alternatively, a flexible rope is connected between the backrest 13 and the slide plate 14, and the linkage of the backrest 13 and the sliding block 16 is realized by using the tension of the rope.

[0030] In this embodiment, one end of the second rotating rod 112 is fixedly connected to the first rotating rod 11, and the other end of the second rotating rod 112 is hingedly connected with the holder 12, and the handle 121 is fixed on the holder 12.

[0031] The hinge between the holder 12 and the second rotating rod 112 can be installed with a damping straight rod 101 to prevent the holder 12 from shaking randomly, and a non-slip rubber sleeve can be provided on the surface of the handle 121 to increase the friction. When working, the user holds the handle 121 to perform chest expansion action, the second rotating rod 112 drives the first rotating rod 11 to rotate, and the holder 12 rotates flexibly with the second rotating rod 112 to fit the user's hand action.

[0032] In this embodiment, the clamping strip 111 is a pair, and the clamping strip 111 is fixed to the opposite inner walls of the slot.

[0033] When the clamping strip 111 is installed on the opposite inner walls of the slot, it can be fixed by welding or high-strength bolts. When working, the guide rail 161 on the sliding block 16 slides in the gap between the pair of clamping strips 111 and the slot, and the sliding block 16 is constrained by the pair of clamping strips 111 to slide more stably, ensuring the accuracy of damping adjustment. In actual application, a T-shaped groove is arranged in the slot, and the guide rail 161 on the sliding block 16 is designed in a T-shaped structure matching the T-shaped groove, which also plays a role in stabilizing the sliding of the sliding block 16.

[0034] In this embodiment, the backrest 13 close to the back side has a curved surface that fits the back, and the backrest 13 is also provided with a back cushion 131 matching the curved surface.

[0035] The curved surface of the backrest 13 close to the back can be designed according to ergonomics to fit the back curve of the human body, and the back cushion 131 can be made of memory foam material to enhance the fit and comfort. When working, the backrest 13 supports the back of the user, and the curved surface and the back cushion 131 effectively distribute the back pressure. In actual use, the comfort experience of the user during training is greatly improved.

[0036] Embodiment 2:

[0037] In this embodiment, the elastic coefficient of the spring 141 on the same slide plate 14 gradually decreases along the direction in which the sliding block 16 is inserted into the slot. The spring 141 on the same slide plate 14 can realize the gradual change of the elastic coefficient by changing the parameters such as the wire diameter and the number of turns of the spring 141. During operation, the springs 141 with different elastic coefficients act in turn during the insertion of the sliding block 16 into the slot, so that the damping changes more smoothly. An alternative is to use multiple groups of elastic rubber sheets with different thicknesses stacked together, and by extruding the rubber sheets with different layers by the sliding block 16, a similar gradual damping effect can be achieved.

[0038] In this embodiment, the first rotating rod 11 and the second rotating rod 112 are perpendicular to each other.

[0039] The first rotating rod 11 and the second rotating rod 112 are perpendicular to each other and are welded or fixed by a right-angle connecting piece. The user operates the second rotating rod 112 to perform a chest expansion exercise, and the perpendicular structure makes the force transmission more direct and efficient, facilitating the user to exert force and improving the training effect.

[0040] When the training device is applied to a cardiopulmonary rehabilitation scene, the damping mechanism can flexibly adjust the training intensity, and the user can accurately change the training difficulty according to his own rehabilitation stage, improving the training specificity; the support mechanism associated with it automatically increases the support area for the user's back during high-damping training, effectively relieving the back pressure and ensuring the safety and comfort of training; the ergonomic design of the holder 12, the curved surface of the backrest 13, and the back cushion 131, etc. improves the user's operation comfort and back fit; multiple components work together, not only providing an efficient and personalized training method for cardiopulmonary rehabilitation training, but also helping to enhance the user's training compliance, promote the better recovery of cardiopulmonary function, and greatly optimize the overall effect of cardiopulmonary rehabilitation training.

[0041] The above embodiments are only used to illustrate the technical solutions of the present disclosure, and not to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacements for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
