[0037] See also Figure 1 to Figure 2 The present invention provides a leg exercise device for rehabilitation of cerebrovascular diseases in neurology, comprising a base plate 10, a leg exercise mechanism 20 and a driving mechanism 30. The two ends of the base plate 10 are respectively a waist end for placing the patient's waist and a foot end for placing the patient's feet. A first slide groove 11 is provided on the top surface of the base plate 10, and a second slide groove 12 is provided on the bottom wall of the first slide groove 11. The width of the second slide groove 12 is smaller than that of the first slide groove 11. The leg exercise mechanism 20 comprises a bent leg assembly 21, a moving assembly 22 and a fixing member 23. The bent leg assembly 21 is provided The first slide groove 11 is provided with the movable assembly 22, and the movable assembly 22 is inserted into the first slide groove 11 and connected with the movable assembly 22 in a sliding manner. The fixed member 23 is slidably provided on the movable assembly 22, and is used to fix the patient's foot. In the initial state, the movable assembly 22 is fixed at the bottom of the movable assembly 22, and is convenient for fixing the foot. The driving mechanism 30 provides power for the leg movement mechanism 20, so that the bent leg assembly 21 can be driven to slide in the second slide groove 12 and the movable assembly 22 can be driven to slide in the first slide groove 11. When in use, the patient's legs are placed on the bottom plate 10, so that the bent leg assembly 21 is located below the legs, and the patient's feet are bound to the fixed member 23. The driving mechanism 30 drives the bent leg assembly 21 to press against the inner side of the knee of the leg and lift upward to bend the leg, and at the same time drives the movable assembly 22 to move toward the patient, so that the patient can do the bent leg movement. Moreover, the fixed member 23 can move upward to increase the movement range of the patient's leg.

[0038] Among them, the driving mechanism 30 includes a driving motor 31, a main rotating shaft 32, a first transmission group 33 and a second transmission group 34. The driving motor 31 is a forward and reverse motor. A first placement groove 13 is provided on the top surface of the foot end of the base plate 10. The first placement groove 13 is connected to the first slide groove 11. The driving motor 31 is arranged in the first placement groove 13. One end of the main rotating shaft 32 is fixedly connected to the output shaft of the driving motor 31, and the other end of the main rotating shaft 32 is connected to one end of the moving component 22. The bent leg component 21 is connected to the main rotating shaft 32 through the first transmission group 33, so that the main rotating shaft 32 drives the driving component to move and lifts the inner side of the knee of the leg upward. The moving component 22 is connected to the fixed component 23 through the second transmission group 34, and the main rotating shaft 32 is driven to rotate by the driving motor 31, so that the moving component 22 moves in the first slide groove 11. At the same time, the main rotating shaft 32 will also drive the second transmission group 34 to make the fixed component 23 slide up and down on the moving component 22.

[0039] Specifically, the bent leg assembly 21 includes a first bent leg rod 211, a second bent leg rod 212, a bent leg hinge seat 213 and a bent leg screw 214. The first bent leg rod 211 and the second bent leg rod 212 are both arranged in the second slide slot 12. The opposite ends of the first bent leg rod 211 and the second bent leg rod 212 are both hingedly connected to the bent leg hinge seat 213. One end of the second bent leg rod 212 away from the bent leg hinge seat 213 abuts against the inner side of the second slide slot 12 near the waist end of the bottom plate 10. On the wall, one end of the first bent leg rod 211 away from the second bent leg rod 212 is hinged with a bent leg slider 215, and the bent leg slider 215 can slide in the second slide slot 12, and the bent leg screw 214 is arranged in the second slide slot 12, one end of the bent leg screw 214 is connected to the main shaft 32 through the first transmission group 33, and the other end of the thread penetrates the bent leg slider 215 and is fixedly connected to the bent leg light rod 216, and the bent leg light rod 216 is rotatably arranged in the second slide slot 12 through the bent leg support plate. Among them, the first transmission group 33 includes a first sprocket 331 and a second sprocket 332, which are fixedly sleeved on the main shaft 32 and the bent leg screw 214 respectively, and the first sprocket 331 and the second sprocket 332 are rotatably connected through the first chain 333. The first sprocket 331 is rotated through the main shaft 32, and then the second sprocket 332 drives the bent leg screw 214 to rotate, thereby promoting the movement of the bent leg assembly 21. The bent-leg hinge seat 213 is used to press against the inner side of the knee to play a supporting role.

[0040] When the patient's legs need to be lifted up at the knees, the main shaft 32 drives the leg bending screw 214 to rotate through the first transmission group 33, so that the leg bending slider 215 moves toward the waist end of the base plate 10, and then the leg bending slider 215 pushes the first leg bending rod 211, so that the leg bending hinge seat 213 moves in the vertical upward direction, against the inner side of the knee, so that the patient's legs are bent, and with the cooperation of the moving component 22, the legs are repeatedly bent and extended to avoid leg muscle atrophy.

[0041] Please also read Figure 3 and Figure 4 The moving assembly 22 includes a moving vertical plate 221, a moving slider 222, a moving light rod 223 and a moving screw 224. The moving slider 222 is slidably arranged in the first slide groove 11. The bottom end of the moving vertical plate 221 is fixedly connected to the top of the moving slider 222 protruding from the first slide groove 11. The moving slider 222 is provided with a first screw hole. One end of the moving light rod 223 is fixedly connected to the end of the main shaft 32 away from the driving motor 31, and the other end passes through the first screw hole and is rotatably connected to the inner side wall of the first slide groove 11 located at the waist end of the bottom plate 10. The outer side surface of the moving screw 224 is provided with an external thread. The moving screw 224 is fixedly sleeved on the moving light rod 223, and the moving screw 224 passes through the first screw hole and is threadedly connected to the moving slider 222. Among them, a through avoidance groove 217 is opened on the side of the curved leg hinge seat 213, and the end of the movable light rod 223 and the movable screw tube 224 away from the main rotating shaft 32 passes through the avoidance groove 217 and is rotatably connected to the inner wall of the first sliding groove 11 located at the waist end of the bottom plate 10, so that the curved leg hinge seat 213 will not touch the movable light rod 223 and the movable screw tube 224 when moving up and down.

[0042] When the driving motor 31 rotates forward, the moving light rod 223 is rotated through the main rotating shaft 32, thereby driving the moving screw 224 to rotate. Due to the threaded connection between the moving screw 224 and the moving slider 222, the moving slider 222 slides in the first sliding groove 11, thereby driving the moving vertical plate 221 to move toward the waist end of the base plate 10. Since the patient's feet are bound to the fixing member 23, the sliding of the moving vertical plate 221 will push the patient's legs to perform leg bending exercises. When the driving motor 31 is reversed, the moving screw 224 drives the moving slider 222 to slide toward the foot end of the base plate 10, thereby causing the moving vertical plate 221 to drive the patient's legs to perform leg extension exercises. The driving motor 31 rotates alternately forward and reverse, so that the moving vertical plate 221 drives the patient's legs to repeatedly perform leg bending and leg extension exercises, so that the patient's legs are exercised, leg muscle atrophy is avoided, and the workload of medical staff is reduced.

[0043] Please also read Figure 5Preferably, the moving assembly 22 further includes two first limiting blocks 225, and the first limiting grooves 14 are provided on the two opposite inner side walls of the first slide groove 11. One end of the two first limiting blocks 225 is respectively fixedly arranged on the two side surfaces of the moving slider 222, and the other end of the two first limiting blocks 225 is respectively inserted into the two first limiting grooves 14 for sliding connection. The provision of the first limiting blocks 225 enhances the stability of the moving slider 222 sliding in the first slide groove 11, and enhances the support force for the patient's foot.

[0044] like Figure 3 and Figure 6 The first gear 341 is connected to the outer side of the movable screw tube 224 through the sliding key 27, and the first gear 341 can slide on the movable screw tube 224. The transmission shaft 343 is rotatably arranged on the top surface of the movable vertical plate 221 through the vertical plate 347. The second gear 342 and the storage wheel 344 are respectively fixedly arranged at both ends of the transmission shaft 343. The first gear 341 and the second gear 342 are rotationally connected through the transmission toothed belt 346. One end of the transmission rope 345 is wound around the storage wheel 344, and the other end is passed through the first sliding groove 236 and fixedly connected to the fixing member 23.

[0045] When the fixing member 23 needs to move upward on the movable vertical plate 221, the main rotating shaft 32 drives the movable screw to rotate, so that the first gear 341 rotates, and the transmission shaft 343 drives the storage wheel 344 to rotate through the transmission toothed belt 346 and the second gear 342, so that the storage wheel 344 continuously retracts the transmission pull rope 345, drives the fixing member 23 to slide upward in the first sliding groove 236, and drives the foot to move upward synchronously. In addition, at this time, the movable vertical plate 221 moves toward the waist end of the bottom plate 10, thereby increasing the degree of compression and extension of the patient's thigh toward the waist, so that the patient can bend his legs more widely; and the fixing member 23 is slightly lower than the top height of the patient's upright thigh when the movable vertical plate 221 is raised.

[0046] Please also read Figure 7, wherein a second sliding groove 29 is provided on the outer side surface of the moving screw tube 224 along the axial direction, one end of the sliding key 27 is fixedly connected to the inner side surface of the first gear 341, and the other end is inserted into the second sliding groove 29 for sliding connection, a rotating groove is provided on the side of the moving slider 222 facing the driving motor 31, a bearing 24 is provided in the rotating groove, a connecting pipe 25 is fixedly connected to the inner side surface of the bearing 24, and the connecting pipe 25 is sleeved on the outer side of the moving screw tube 224 at intervals, a T-shaped annular groove is provided on the side of the first gear 341 facing the moving slider 222, a T-shaped ring block 26 is slidably provided in the annular groove, and the end of the ring block 26 extending to the outer side of the annular groove is fixedly connected to the end of the connecting pipe 25 away from the bearing 24.

[0047] When the movable screw 224 drives the first gear 341 to rotate, the connecting tube 25 rotates relative to the movable slider 222. At the same time, since the connecting tube 25 connects the first gear 341 and the movable slider 222 together, the first gear 341 slides on the movable screw 224 along the direction of the second sliding groove 29 while rotating, thereby realizing the synchronous movement of the movable slider 222 and the first gear 341. Therefore, the movable screw 224 can drive the fixing member 23 to slide up and down on the movable vertical plate 221, and can also drive the movable vertical plate 221 to slide.

[0048] like Figure 5 and Figure 8 In this embodiment, the fixing member 23 includes a fixing slider 231, a supporting arc plate 232, a supporting seat 233 and a fixing belt 234. The fixing slider 231 is slidably arranged in the first sliding groove 236. One end of the supporting arc plate 232 is fixedly connected to the side of the fixing slider 231 protruding from the first sliding groove 236, and the inner side of the supporting arc plate 232 faces upward. The supporting seat 233 is rotatably connected to the inner side of the supporting arc plate 232 through a supporting rod 235, and the supporting seat 233 can rotate 360 ​​degrees in the supporting arc plate 232. The two ends of the fixing belt 234 are respectively connected to the top two sides of the side of the fixing slider 231 protruding from the first sliding groove 236. Among them, the top surface of the supporting seat 233 is concave in shape to match the shape of the patient's heel, and the fixing belt 234 is elastic so that the patient's foot can be fixed on the fixing slider 231 using different sizes of the patient's foot.

[0049] By placing the patient's heel on the support seat 233, the sole of the foot is attached to the fixed slider 231, and the fixing belt 234 is used to fix the patient's foot to prevent the foot from shaking; and the heel can rotate 360 ​​degrees relative to the support arc plate 232 to adapt to the inclination of the leg when the height of the support seat 233 is raised.

[0050] In this embodiment, in order to lift the patient's knee first and facilitate bending the leg later, the number of teeth of the first sprocket 331 is greater than the number of teeth of the second sprocket 332, so that the rotation speed of the bending leg screw 214 is greater than the rotation speed of the moving screw, so that the knee is lifted first and the moving vertical plate 221 starts to slide. In the initial position, the horizontal distance between the bending leg slider 215 and the driving motor 31 is greater than the horizontal distance between the moving slider 222 and the driving motor 31, so that the bending leg slider 215 can move to the bending leg light rod 216 in a short time, thereby limiting the further rise of the bending leg articulated seat 213.

[0051] When the main shaft 32 rotates, the bent leg screw 214 drives the bent leg slider 215 to move, thereby squeezing the first bent leg rod 211, so that the bent leg hinge seat 213 presses against the inner side of the knee, lifts the knee, and thus slightly bends the leg; at the same time, the moving vertical plate 221 moves to push the foot, and the leg continues to bend; when the bent leg slider 215 moves to the connection between the bent leg light rod 216 and the bent leg screw 214, the bent leg slider 215 stops moving, and the bent leg hinge seat 213 stays at the height at this time, and the moving vertical plate 221 continues to push the patient's leg to bend.

[0052] When the patient's legs are doing leg extension exercise, the movable vertical plate 221 moves toward the foot end of the base plate 10. When the inner side of the knee is pressed against the leg bending hinge seat 213, the first leg bending rod 211 squeezes the leg bending slider 215 to slide onto the leg bending screw 214. At this time, the leg bending screw 214 rotates in the opposite direction, so that the leg bending screw 214 drives the slider to move toward the foot end of the base plate 10, and the leg bending hinge seat 213 moves downward; the above steps are repeated in this way, so that the patient's legs can perform repeated exercises of bending and extending the legs.

[0053] like Figure 2 As shown, in this embodiment, a binding belt 40 is provided on the bottom plate 10, and a binding ring 41 is provided on the side of the bottom plate 10. One end of the binding belt 40 is fixed to one side of the bottom plate 10, and the other end is passed around the top of the bottom plate 10, and then passed through the binding ring 41 and then bonded to the top surface of the binding belt through Velcro. When the patient's legs are bent, the binding belt is used to fix the patient's waist to prevent the waist from separating from the bottom plate 10, and also to prevent the patient's waist from moving.

[0054] In this embodiment, there are two leg exercise mechanisms 20 and two driving mechanisms 30 . The two leg exercise mechanisms 20 are arranged in parallel on the base plate 10 to respectively drive the patient's legs to perform flexion and extension exercises.

[0055] The working principle of the present invention is as follows: when in use, the patient's legs are first placed at the position of the first slide slot 11, the feet are bound to the fixed slider 231, and the patient's waist is fixed with the binding belt 40; then the driving motor 31 is started to rotate forward to rotate the main shaft 32, and the first transmission group 33 drives the bent leg screw 214 to rotate, so that the bent leg screw 214 drives the bent leg slider 215 to move toward the waist end of the bottom plate 10, and then the bent leg slider 215 pushes the first bent leg rod 211, so that the bent leg hinge seat 213 presses against the inner side of the knee to lift up, so that the patient's leg is bent; when the inner side of the knee is lifted up, the main shaft 3 The movable solenoid 224 is driven to rotate, so that the movable solenoid 224 drives the movable slider 222 to slide toward the waist end of the bottom plate 10, so that the movable vertical plate 221 pushes the patient's foot to bend the leg; while the movable solenoid 224 rotates, the movable solenoid 224 drives the first gear 341 to rotate, so that the transmission shaft 343 drives the storage wheel 344 to rotate, so that the transmission pull rope 345 is continuously retracted on the storage wheel 344, so that the transmission pull rope 345 pulls the fixed slider 231 to move upward on the movable vertical plate 221, so that the height of the foot is increased while the leg is bent, so that the leg is bent and pressed toward the waist direction;

[0056] When the patient has finished bending his legs, the driving motor 31 reverses, and the moving vertical plate 221 moves the foot toward the foot end of the base plate 10, so that the leg begins to stretch; when the inner side of the knee is pressed on the bending leg hinge seat 213, the bending leg slider 215 moves to the bending leg screw 214, so that the bending leg slider 215 moves toward the foot end of the base plate 10, and the bending leg hinge seat 213 drops in height. While the moving vertical plate 221 slides back, the fixed slider 231 moves downward until the leg is stretched; the above-mentioned leg bending and stretching are repeated to exercise the leg muscles.

[0057] Beneficial effects of the present invention: the leg exercise device for rehabilitation of cerebrovascular diseases in the neurology department drives the bending leg slider 215, the moving slider 222 and the fixed slider 231 to slide by driving the motor 31 to rotate forward at the same time, so that the bending leg hinge seat 213 lifts the knee, and the moving vertical plate 221 pushes the foot to bend the leg, while the foot height rises, so that the leg bends toward the waist, and then the driving motor 31 reverses to stretch the leg, so that the leg repeats the bending and stretching movements, so that the leg muscles are exercised, and the workload of medical staff is also reduced; and the binding belt 40 fixes the patient's waist to prevent the patient's legs from bending and moving the waist.
