[0019] like Figures 1 to 5 As shown, a leg rehabilitation training device for lying patients of the present invention comprises a frame 1 and a plurality of support shafts 3 rotatably mounted in the frame 1, the plurality of support shafts 3 being coaxial, the frame 1 being provided with a lying table 2 for the patient to lie flat, each support shaft 3 being provided with a counterweight wheel 4, the outer wall of the counterweight wheel 4 being composed of a slope 5 and a transition plane 6, and the distance between the slope 5 and the axis of the support shaft 3 gradually changes from one end of the slope 5 to the other end thereof, the transition plane 6 being used to connect the two ends of the slope 5, and the transition plane 6 and the axis of the support shaft 3 being parallel to each other, each counterweight wheel 4 being provided with a mounting frame 10, a rolling wheel 11 being rotatably mounted on the mounting frame 10, the rolling wheel 11 rolling on the outer wall of the counterweight wheel 4, and a pushing structure for providing the rolling wheel 11 with an elastic thrust toward the axis of the support shaft 3 is provided on the mounting frame 10; Each supporting shaft 3 is provided with a connecting rod 7, and the connecting rods 7 are connected by a rotating shaft 8, and the rotating shaft 8 is rotatably connected to the connecting rod 7, and a plurality of pedals 9 are provided on the rotating shaft 8; In the present invention, the patient can lie flat on the reclining platform 2, and the patient's feet can be placed on the pedals 9. In order to prevent the feet from being separated from the pedals 9, a number of straps can be provided on the pedals 9. The arrangement of a number of pedals 9 on the rotating shaft 8 can facilitate the patient to place his feet on the pedals 9 at any position, so as to facilitate the patient's training. The support shaft 3 can be used to support the counterweight wheels 4, and the number of counterweight wheels 4 can be adjusted according to actual training needs, such as Figure 2 As shown, two weighted wheels 4 are provided, and they are distributed left and right, and the patient's feet can be placed on the pedals 9 located between the two weighted wheels 4; The slope surface 5 on the outer wall of the counterweight wheel 4 is vortex-shaped. Along the trajectory direction of the slope surface 5, the distance between the slope surface 5 and the axis of the support shaft 3 gradually increases or decreases. The transition plane 6 can be used to transitionally connect the two ends of the slope surface 5, so that the slope surface 5 and the transition plane 6 form a complete outer wall of the counterweight wheel 4; the transition plane 6 is parallel to the axis of the support shaft 3, that is, there is a certain distance between the surface where the transition plane 6 is located and the axis of the support shaft 3, so that the transition plane 6 can be avoided from being set along the radial direction of the support shaft 3. When the support shaft 3 and the counterweight wheel 4 rotate, this setting method of the transition plane 6 can provide an inclined thrust to the rolling wheel 11, thereby allowing the transition plane 6 to push the rolling wheel 11 to move, and avoiding the situation where the thrust of the transition plane 6 on the rolling wheel 11 is perpendicular to the moving direction of the rolling wheel 11 on the pushing structure when the transition plane 6 is along the radial direction of the support shaft 3, resulting in the transition plane 6 being unable to push the rolling wheel 11 to move; the mounting frame 10 is mainly used to support the rolling wheel 11; It should be noted that in the natural state, the rolling wheel 11 is located at an angle between the end of the slope 5 close to the axis of the support shaft 3 and the transition plane 6. At this time, the distance between the rolling wheel 11 and the axis of the support shaft 3 is the smallest, and the rotating shaft 8 and the pedal 9 are located above the axis of the support shaft 3. When the patient is lying flat on the couch 2, the patient's feet are placed on the pedals 9, and the patient's legs are in a bent state. When the legs are stretched with force, the patient can push the support shaft 3 to rotate through the pedals 9, the rotating shaft 8 and the connecting rod 7. At this time, since the line between the pedals 9 and the support shaft 3 is at an angle to the direction of the patient's thrust on the pedals 9, the patient can provide a more effective pushing force for the pedals 9, and avoid the line between the pedals 9 and the support shaft 3 being colinear with the direction of the patient's thrust on the pedals 9 or the angle being too small, the conversion rate of the patient's thrust on the pedals 9 into the rotation of the support shaft 3 is low, which makes it more difficult for the patient to push the support shaft 3 to rotate; when the support shaft 3 rotates, it will use the transition plane 6 to push the rolling wheel 11 to move in the vertical direction, that is, the rolling wheel 11 moves in the direction away from the support shaft 3. When the rolling wheel 11 When moving from the transition plane 6 to the slope 5, the patient pushes the pedal 9 to move a specified distance. At this time, the support shaft 3 rotates a specified angle, and the line between the support shaft 3 and the pedal 9 has not yet formed a colinear state with the direction of the patient's thrust on the pedal 9. Since the distance between the slope 5 and the support shaft 3 gradually changes, the thrust provided by the rolling wheel 11 of the pushing structure can act on the slope 5 and actively push the counterweight wheel 4 to rotate, thereby actively driving the patient's foot to perform a circular motion, and the patient's legs synchronously perform a circular stretching motion. This part is similar to pedaling a bicycle, but this part is for assisting the patient's leg motion rather than the patient's active leg motion; when the rolling wheel 11 rolls back to the initial position, the counterweight wheel 4 rotates one circle. At this time, the patient can apply force to the pedal 9 again to rotate the counterweight wheel 4, thereby achieving the patient's rehabilitation training; In actual use, the interval in which the patient pushes the rolling wheel 11 to roll on the transition plane 6 is at most a quarter of the rotation of the support shaft 3. This allows the patient to apply force only within the specified interval, and the force applied is more effectively transmitted to the support shaft 3, avoiding applying force throughout the entire process and causing patient fatigue, which would prolong the patient's training time. By allowing the patient to actively apply force and rotate the counterweight wheel 4 within the specified rotation interval of the counterweight wheel 4, and then allowing the counterweight wheel 4 to reversely drive the patient's legs to move within other rotation intervals of the counterweight wheel 4, an active and passive alternating training mode for the patient is achieved. In this mode, the patient's legs can achieve various movement modes such as kicking and extension movement, foot rotation movement, and leg stretching movement, thereby increasing the diversity of training and helping the patient to recover health faster; by allowing the patient to apply force only within the specified interval, the thrust applied by the patient to the pedal 9 can be more effectively converted into the rotational power of the counterweight wheel 4, thereby reducing the difficulty of the patient driving the counterweight wheel 4 to rotate and facilitating patient training.
[0020] Furthermore, a connection structure is provided between the rolling wheel 11 and the corresponding counterweight wheel 4. The connection structure includes two guide grooves 12 provided on the wall at both ends of the counterweight wheel 4. The shape of the guide groove 12 is consistent with the shape of the counterweight wheel 4. A slide post 13 is slidably provided in the guide groove 12. A plurality of connecting arms 14 are provided on the mounting frame 10. The slide posts 13 are mounted on the corresponding connecting arms 14. Since the rolling wheel 11 needs to roll on the outer wall of the counterweight wheel 4, if the rolling wheel 11 is only in contact with the outer wall of the counterweight wheel 4, the counterweight wheel 4 and the rolling wheel 11 will be separated due to the rotational inertia of the counterweight wheel 4, causing the rolling wheel 11 to collide with the counterweight wheel 4 when resetting. In order to ensure that the counterweight wheel 4 and the rolling wheel 11 are always in contact, they can be connected together through a connecting structure. Specifically, the rolling wheel 11 is guided by the guide groove 12 and the sliding column 13, thereby limiting the distance between the rolling wheel 11 and the outer wall of the counterweight wheel 4, making it convenient for them to always be in contact with each other, and the connecting arm 14 can support the sliding column 13.
[0021] Furthermore, the mounting frame 10 is provided with a plurality of sliders 15 that slide around the rotation axis of the rolling wheel 11, and the sliders 15 are fixedly connected to the corresponding connecting arms 14; Since the shape of the guide groove 12 is consistent with the shape of the counterweight wheel 4, at different positions of the guide groove 12, the corresponding position on the outer wall of the counterweight wheel 4 can only be kept constant by the length of the line segment perpendicular to the guide groove 12. If the connecting arm 14 is relatively fixed to the mounting frame 10, that is, the direction of the connecting arm 14 on the mounting frame 10 cannot be adjusted, then there will be a stuck phenomenon, for example, Figure 3As shown, at the position of the transition plane 6, if the connecting arm 14 remains vertical, the connecting arm 14 cannot be perpendicular to the transition plane 6, that is, the distance between the sliding column 13 and the rotation axis of the rolling wheel 11 will be greater than the minimum distance between the guide groove 12 and the rotation axis of the rolling wheel 11, and the minimum distance is the constant distance between the guide groove 12 and the outer wall of the counterweight wheel 4. Therefore, when the sliding column 13 moves to the part of the guide groove 12 corresponding to the slope surface 5, the rolling wheel 11 will separate from the outer wall of the slope surface 5 or become stuck; In order to solve the above problem and ensure that the rolling wheel 11 can move smoothly on the outer wall of the counterweight wheel 4, it is necessary to enable the slide column 13 to rotate relative to the rotation axis of the rolling wheel 11, that is, to use the slider 15 to slide on the mounting frame 10 so that when the slide column 13 moves to any position on the guide groove 12, the connecting arm 14 is always perpendicular to the position of the guide groove 12.
[0022] Furthermore, the pushing structure includes a fixed platform 16 and two oblique arms 17 rotatably mounted on the fixed platform 16. The two oblique arms 17 are parallel to each other. An oblique arm 18 is rotatably mounted on each oblique arm 17. The two oblique arms 18 are rotatably connected to the mounting frame 10. The two oblique arms 18 are parallel to each other. A guide plate 19 is rotatably connected between the two oblique arms 17 and between the two oblique arms 18. The surfaces on the fixed platform 16 where the ends of the two oblique arms 17 are located, the surfaces on the mounting frame 10 where the ends of the two oblique arms 18 are located, and the guide plates 19 are all parallel to each other. The first oblique arm 17 is connected to the corresponding second oblique arm 18 by an elastic body 20; The fixed platform 16 is mainly used to support the inclined arm 17. The above-mentioned setting of the two guide plates 19 can ensure that the two inclined arms 17 and the two inclined arms 18 are always parallel to each other. When the rolling wheel 11 moves, the direction of the mounting frame 10 and the rolling wheel 11 remains unchanged, thereby preventing the rolling wheel 11 from tilting and failing to make normal contact with the outer wall of the counterweight wheel 4 when the inclined arm 17 or the inclined arm 2 18 rotates. The elastic body 20 can provide elastic thrust for the inclined arm 17 and the corresponding inclined arm 2 18, so that the rolling wheel 11 provides rotational power for the counterweight wheel 4 when it moves to the slope 5.
[0023] Furthermore, an arc-shaped sleeve 21 is provided on the oblique arm 17, and an arc-shaped slide rod 22 is slidably provided in the arc-shaped sleeve 21. The arc-shaped slide rod 22 is connected to the corresponding oblique arm 2 18. An air hole 23 is opened on the outer wall of the arc-shaped sleeve 21 and communicates with the interior of the arc-shaped sleeve 21. The arc sleeve 21 and the arc slide bar 22 are both arc-shaped, and their axes coincide with the rotation axis of the inclined arm 2 18 on the inclined arm 1 17. When the inclined arm 1 17 and the inclined arm 2 18 rotate relative to each other, the arc slide bar 22 slides on the arc sleeve 21, and the internal space of the arc sleeve 21 increases or decreases. The inside of the arc sleeve 21 is connected to the outside of the arc sleeve 21 through the air hole 23. The air hole 23 can limit the air circulation speed, thereby limiting the movement speed of the arc slide bar 22 on the arc sleeve 21, which is convenient for limiting the speed at which the pushing structure pushes the rolling wheel 11 to move, thereby achieving buffering of the rolling wheel 11, avoiding the rolling wheel 11 from moving too fast and causing the counterweight wheel 4 to rotate too fast and cause harm to the patient, and ensuring that the counterweight wheel 4 rotates slowly and smoothly.
[0024] Furthermore, the distance between the fixed platform 16 and the corresponding axis of the support shaft 3 can be adjusted; since the thrust it can provide during patient training is directly related to the patient's recovery status, when the thrust provided by the rolling wheel 11 to the counterweight wheel 4 is large, the patient cannot push the counterweight wheel 4 to rotate. In order to facilitate the application of the device to different patients, the thrust of the pushing structure can be adjusted. Specifically, by adjusting the distance between the fixed platform 16 and the axis of the support shaft 3, the elastic deformation of the elastic body 20 is adjusted, thereby adjusting the thrust provided by the rolling wheel 11 to the counterweight wheel 4; the fixed platform 16 can be slidably set on the frame 1, and the fixed platform 16 and the frame 1 are fastened by bolts. When the position of the fixed platform 16 needs to be adjusted, it is only necessary to loosen the bolts and slide the fixed platform 16.
[0025] Furthermore, since the lengths of patients' legs are inconsistent, the distance between the axis of the rotating shaft 8 and the axis of the supporting shaft 3 needs to be adjustable to facilitate the patient to perform rehabilitation training in the most comfortable posture and to facilitate training according to the patient's allowed range of motion.
[0026] Furthermore, the connecting rod 7 passes through the corresponding support shaft 3 and is slidably connected to each other. A plurality of slots 24 are provided on the side wall of the connecting rod 7 along the length direction of the connecting rod 7. The slots 24 are inclined. A buckle 25 is provided at the end of the support shaft 3, and a plurality of inserting plates 26 are provided on the buckle 25. The inserting plates 26 slide through the support shaft 3 and are inserted into the corresponding slots 24. The buckle 25 and the support shaft 3 are connected by a spring 27. When the distance between the rotating shaft 8 and the support shaft 3 needs to be shortened, the operator only needs to press the connecting rod 7, and the inclined characteristic of the slot 24 can be used to push the latch hand 25 to move in the direction away from the support shaft 3, and the latch plate 26 can be pulled out of the slot 24; when the distance between the rotating shaft 8 and the support shaft 3 needs to be increased, the operator can directly pull the latch hand 25 to separate the latch plate 26 from the slot 24, and then move the connecting rod 7.
[0027] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
