Description

Technical Field

[0001] The utility model belongs to the technical field of rehabilitation department equipment, and more specifically, particularly relates to a lower limb linkage rehabilitation training device. Background Art

[0002] After a patient's lower limbs are injured due to an accident, they need to perform exercises during the recuperation process to help with recovery.

[0026] In this embodiment, the patient lies flat on the bed 1, with the buttocks located in the gap between the bed 1 and the support plate 1 2, and the knee joints located in the gap between the support plate 1 2 and the support plate 2 3. The bed 1, the support plate 1 2 and the support plate 2 3 have various sizes to adapt to the different heights and body shapes of patients. The patient puts the thighs and calves on two cushions 27 respectively and binds the legs with Velcro straps 28. According to different load requirements, the gripping protrusion 26 slides the baffle 25 to expose the ventilation groove on the top of the hollow shaft 4. The larger the exposed area, the better. The resistance is smaller, and then the hip and knee joints are bent to fold the legs. When the hip and knee joints rotate, the hollow shaft 1 4 and the hollow shaft 2 6 rotate relative to each other. The hollow shaft 2 6 drives the large gear 1 12 to rotate through the round rod 9, the connecting rod 10 and the connecting shaft 1 11. The large gear 1 12 drives the small gear 1 13, the connecting shaft 2 14 and the large gear 2 15 to rotate, thereby driving the small gear 2 16 to rotate, and through the combination of large and small gears, the rotation angle of the small gear 2 16 is increased, thereby increasing the screw 19 has a rotation angle. Due to the limitation of the slider 31, the sealing plate 22 and the threaded tube 21 rotate with the hollow shaft 26. Since the rotation angle of the screw 19 is much larger than the rotation angle of the hollow shaft 26, the screw 19 pushes the threaded tube 21 and the sealing plate 22 to slide horizontally through the thread, so that the air in the hollow shaft 26 and the hollow shaft 4 is discharged through the ventilation groove on the top of the hollow shaft 4. The air resistance during the discharge provides rotation damping, and cooperates with the patient's limb weight to provide weight for patient training, and the weight can be adjusted linearly, which solves the problem that most existing lower limb rehabilitation training devices use weight plates to perform light weight training on the patient's legs, and it is difficult to linearly adjust the weight during the stacking process of the weight plates, so that the weight is too heavy and easy to cause injury or the weight is too small to achieve a good rehabilitation training effect. The muscles at the knee joint and hip joint can be trained in a linked manner to improve the training recovery effect. The two sets of connecting rods 10 are at different inclination angles to adapt to the rotation direction of different joints and avoid collision with the fixed plate 17 and the pinion 13.

[0027] Embodiment 2:

[0028] See also Figures 1-4 On the basis of the first embodiment, the utility model provides a technical solution: the bottom of the bed body 1 and the support plate 2 are fixedly connected with a fixing seat 29, the middle part of the fixing seat 29 is penetrated and slidably connected with an L-shaped plate 30, the top of the L-shaped plate 30 on one side is slidably connected to the bottom of the bed body 1 and the support plate 2, and the top of the L-shaped plate 30 on the other side is slidably connected to the bottom of the support plate 2 and the support plate 3.

[0029] In this embodiment: When it is necessary to train the muscles at the knee joint or the hip joint separately, pull the L-shaped plate 30 to support the first support plate 2 or the second support plate 3. When the bottom of the first support plate 2 is blocked by the L-shaped plate 30 and the bottom of the second support plate 3 does not contact the L-shaped plate 30, the bed body 1 and the first support plate 2 remain in a horizontal state. At this time, the second support plate 3 can be rotated separately to train the muscles at the knee joint. Similarly, when the bottom of the second support plate 3 is blocked by the L-shaped plate 30 and the bottom of the first support plate 2 does not contact the L-shaped plate 30, the muscles at the hip joint can be trained separately, and the muscles at the back of the leg can be stretched. It has strong adjustability and is more flexible to use.

[0030] Working principle: According to different requirements for load-bearing, hold the convex block 26 and slide the baffle 25 to expose the ventilation groove at the top of the first hollow shaft 4. The larger the exposed area, the smaller the resistance. Then bend the hip and knee joints to fold the leg. When the hip and knee joints rotate, the first hollow shaft 4 and the second hollow shaft 6 rotate relatively. The second hollow shaft 6 drives the first large gear 12 to rotate through the round rod 9, the connecting rod 10 and the first connecting shaft 11. The first large gear 12 drives the first small gear 13, the second connecting shaft 14 and the second large gear 15 to rotate, thereby driving the second small gear 16 to rotate. And through the combination of large and small gears, the rotation angle of the second small gear 16 is increased, thereby increasing the rotation angle of the screw 19. Due to the limitation of the slider 31, the sealing plate 22 and the threaded pipe 21 rotate following the second hollow shaft 6. Since the rotation angle of the screw 19 is much larger than the rotation angle of the second hollow shaft 6, the screw 19 pushes the threaded pipe 21 and the sealing plate 22 to slide horizontally through the thread, so that the air in the second hollow shaft 6 and the first hollow shaft 4 is discharged through the ventilation groove at the top of the first hollow shaft 4. The air resistance during discharge provides rotational damping, and together with the weight of the patient's limb, it provides load-bearing for the patient's training, and the load-bearing can be linearly adjusted. When it is necessary to train the muscles at the knee joint or the hip joint separately, pull the L-shaped plate 30 to support the first support plate 2 or the second support plate 3. When the bottom of the first support plate 2 is blocked by the L-shaped plate 30 and the bottom of the second support plate 3 does not contact the L-shaped plate 30, the bed body 1 and the first support plate 2 remain in a horizontal state. At this time, the second support plate 3 can be rotated separately to train the muscles at the knee joint. Similarly, when the bottom of the second support plate 3 is blocked by the L-shaped plate 30 and the bottom of the first support plate 2 does not contact the L-shaped plate 30, the muscles at the hip joint can be trained separately, and the muscles at the back of the leg can be stretched.

Many modifications and variations are obvious to those of ordinary skill in the art.
