Detailed implementation manners

[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation to the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: a balance training rehabilitation device with an adjustment function, including a bottom plate 1. An adjustment cavity 2 for providing an installation space for the adjustment component is opened inside the bottom plate 1. Two mounting plates 3 for structural support are fixedly connected to the upper side surface of the bottom plate 1. A rotating shaft 4 for providing structural support and a rotating function is rotatably connected between the two mounting plates 3. A through groove extending into the inside of the adjustment cavity 2 is opened on the upper side surface of the bottom plate 1. The outer surface of the rotating shaft 4 extends into the inside of the adjustment cavity 2 through the through groove. A balance plate 5 for the patient to stand on and support is fixedly connected to the outer surface of the rotating shaft 4. A support block 6 for further supporting the rotating shaft 4 is fixedly connected to the bottom wall of the adjustment cavity 2. An arc adapted to the rotating shaft 4 is opened on the upper side surface of the support block 6. A limiting rod 7 for restricting the trajectory of the structure is fixedly connected to the inner wall of the adjustment cavity 2. A push plate 8 for pushing the structure to move is slidably sleeved on the outer surface of the limiting rod 7. A first telescopic rod 9 for connection and support is fixedly connected to the side surface of the push plate 8 close to the rotating shaft 4.

[0025] A second telescopic rod 10 for connection and support is slidably sleeved inside the first telescopic rod 9. One end of the second telescopic rod 10 close to the rotating shaft 4 slidably penetrates out of the first telescopic rod 9. A friction plate 11 for attaching to the rotating shaft 4 and adjusting the frictional resistance is fixedly connected to one end of the second telescopic rod 10 close to the rotating shaft 4. When the push plate 8 moves, the friction plate 11 is pushed close to the rotating shaft 4 by means of the first telescopic rod 9, the second telescopic rod 10 and the spring 12. After the friction plate 11 contacts the rotating shaft 4, the spring 12 will be compressed and the second telescopic rod 10 will contract into the inside of the first telescopic rod 9. At this time, the friction plate 11 is pushed by the elastic force of the spring 12, and then the frictional force between the friction plate 11 and the rotating shaft 4 is used to reduce the frictional force when the rotating shaft 4 rotates. The surface of the friction plate 11 close to the rotating shaft 4 is set to be an arc shape adapted to the rotating shaft 4. A spring 12 for pushing the friction plate 11 to fit with the rotating shaft 4 is fixedly connected between the friction plate 11 and the push plate 8. A resistance adjustment component is arranged inside the adjustment cavity 2. By means of the elastic force of the spring 12, the friction plate 11 is pushed to contact the rotating shaft 4, thereby adjusting the flexibility of the rotating shaft 4.

[0026] The resistance adjustment component includes a bidirectional threaded rod 13 for power drive. The bidirectional threaded rod 13 is rotatably connected to the left inner wall of the adjustment cavity 2. A speed change cavity 14 for providing an installation space for the structure is opened inside the bottom plate 1. The right end of the bidirectional threaded rod 13 rotatably penetrates into the inside of the speed change cavity 14. Two push plates 8 are respectively threadedly sleeved on two opposite threads of the bidirectional threaded rod 13. A rotating shaft 15 for providing support for the structure installation is rotatably connected to the left inner wall of the speed change cavity 14. A first gear 16 for power transmission is sleeved on the outer surface of the rotating shaft 15. The right end of the bidirectional threaded rod 13 is also fixedly connected with a first gear 16 for power transmission. The two first gears 16 are meshed and connected. After the first gear 16 rotates, it drives the bidirectional threaded rod 13 to rotate in cooperation with the first gear 16 below. Since the movement track of the push plate 8 is restricted by the limiting rod 7, when the bidirectional threaded rod 13 rotates, the two push plates 8 will be driven to move in opposite directions synchronously.

[0027] A first speed-changing gear 17 for changing the rotation speed is fixedly connected to the right end of the rotating shaft 15. A knob 18 for the user to operate is arranged on the right side surface of the bottom plate 1. A second rotating shaft 19 for power transmission and structural support is fixedly connected to the left side surface of the knob 18. The left end of the second rotating shaft 19 rotatably penetrates into the interior of the speed-changing cavity 14. A second speed-changing gear 20 for cooperating with the first speed-changing gear 17 to change the rotation speed is fixedly connected to the left end of the second rotating shaft 19. The second speed-changing gear 20 is meshed and connected with the first speed-changing gear 17. When a patient initially recovers and uses this balance trainer, the second rotating shaft 19 can be synchronously driven to rotate by the knob 18. After the second rotating shaft 19 rotates, the second speed-changing gear 20 is synchronously driven to rotate. After the second speed-changing gear 20 rotates, the first speed-changing gear 17 is driven to rotate. And since the diameter of the first speed-changing gear 17 is larger than that of the second speed-changing gear 20, deceleration will occur when the second speed-changing gear 20 drives the first speed-changing gear 17 to rotate.

[0028] The first speed-changing gear 17 synchronously drives the upper first gear 16 to rotate through the rotating shaft 15. A groove is formed on the upper side surface of the balance plate 5. An adjusting bolt 21 for structural adjustment is rotatably connected to the inner wall of the groove. The lower end of the adjusting bolt 21 rotatably penetrates out of the lower side surface of the balance plate 5. A limiting sleeve 22 for restricting the movement track of the structure is fixedly connected to the lower side surface of the balance plate 5. An adjusting sleeve 23 is slidably sleeved on the outer surface of the limiting sleeve 22. A threaded sleeve 24 for cooperating with the adjusting bolt 21 to move is fixedly connected to the bottom wall of the adjusting sleeve 23. The threaded sleeve 24 is threadedly sleeved on the outer surface of the adjusting bolt 21. When adjusting the swaying angle of the balance plate 5, the adjusting bolt 21 can be rotated. Since the movement tracks of the adjusting sleeve 23 and the threaded sleeve 24 are restricted by the limiting sleeve 22, the threaded sleeve 24 will be synchronously driven to move in the vertical direction when the adjusting bolt 21 rotates. Furthermore, the distance between the adjusting sleeve 23 and the upper surface of the bottom plate 1 is shortened. The distance from the bottom plate 1 is adjusted through the displacement of the adjusting sleeve 23, thereby restricting the maximum amplitude when the balance plate 5 sways, making the applicable range of this balance trainer wider.

[0029] Working principle: When a patient initially recovers and uses this balance trainer, the second rotating shaft 19 can be synchronously driven to rotate by turning the knob 18. After the second rotating shaft 19 rotates, it synchronously drives the second speed-changing gear 20 to rotate. After the second speed-changing gear 20 rotates, it drives the first speed-changing gear 17 to rotate. And since the diameter of the first speed-changing gear 17 is larger than that of the second speed-changing gear 20, deceleration will occur when the second speed-changing gear 20 drives the first speed-changing gear 17 to rotate. The first speed-changing gear 17 synchronously drives the upper first gear 16 to rotate through the rotating shaft 15. After the first gear 16 rotates, it cooperates with the lower first gear 16 to drive the bidirectional threaded rod 13 to rotate. Since the movement trajectory of the push plate 8 is restricted by the limiting rod 7, when the bidirectional threaded rod 13 rotates, it will synchronously drive the two push plates 8 to move in opposite directions. When the push plate 8 moves, it pushes the friction plate 11 close to the rotating shaft 4 by means of the first telescopic rod 9, the second telescopic rod 10 and the spring 12. After the friction plate 11 contacts the rotating shaft 4, it will compress the spring 12 and cause the second telescopic rod 10 to contract into the interior of the first telescopic rod 9. At this time, the friction plate 11 is pushed by the elastic force of the spring 12, and then the friction force between the friction plate 11 and the rotating shaft 4 is used to reduce the friction force when the rotating shaft 4 rotates. At the same time, when adjusting the shaking angle of the balance plate 5, the adjusting bolt 21 can be rotated. Since the movement trajectories of the adjusting sleeve 23 and the threaded sleeve 24 are restricted by the limiting sleeve 22, when the adjusting bolt 21 rotates, it will synchronously drive the threaded sleeve 24 to move in the vertical direction, thereby shortening the distance between the adjusting sleeve 23 and the upper surface of the bottom plate 1.

[0030] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
