Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of knee joint rehabilitation equipment, and particularly relates to a knee joint recovery exercise device. BACKGROUND

[0002] After the knee joint is damaged and operated, the knee joint cannot be bent due to previous diseases or operation, and the knee joint needs to be moved and exercised for rapid recovery.

[0003] The knee joint is a human joint connecting the thigh and the lower leg, and in the training process, the knee joint is usually exercised by bending the thigh and the lower leg. By bending the thigh and the lower leg, the activity of the knee joint meniscus can be increased, and appropriate activity can enable the knee joint to adapt quickly and thus play a recovery role. In the existing exercise mode, the patient needs to lie on a bed, and the nursing staff needs to artificially assist the patient in bending the thigh and the lower leg. This is labor-intensive, and the patient needs to lie on the bed for a long time. Lack of exercise will cause the patient's heart and lung function to gradually decline. Therefore, in order to ensure that the patient can exercise the knee joint under the premise of having a certain amount of exercise, the nursing staff needs to help the patient get up on a walking aid and exercise by slowly moving the patient's body. However, this method is suitable for patients who have a certain exercise capacity in the recovery period. In the early recovery period, the patient's knee joint may still have some pain, and the traditional walking aid is not suitable for such patients.

[0004] To solve the above problems, the present application provides a knee joint recovery exercise device which can exercise the heart and lung function and increase the exercise intensity according to the patient's condition. SUMMARY

Therefore, they should not be construed as limiting the invention.

[0018] refer to Figures 1 to 12 A knee joint rehabilitation exercise device includes a horizontal base plate 1, an L-shaped sliding plate 3, a first vertical mounting rod 7, a second vertical mounting rod 8, a second vertical mounting plate 25, a horizontal mounting plate 2501, a stool 11, a backrest 12, a lumbar massage roller 14, a thigh support plate 5, a calf support plate 4, a fixing component 6, a flexible air cushion 15, a sliding mechanism, an operating mechanism, a bending mechanism, a reciprocating mechanism, and an air replenishment mechanism. Two L-shaped sliding plates 3 are movably installed on the upper end of the horizontal base plate 1. The upper ends of the two L-shaped sliding plates 3 are respectively fixedly installed with first vertical mounting rods 7, and the rear ends of the two first vertical mounting rods 7 are respectively fixedly installed with second vertical mounting rods 8. Both L-shaped sliding plates 3 are driven to slide by a sliding mechanism, and the two L-shaped sliding plates 3 drive the air replenishment mechanism described later under the drive of the sliding mechanism. The upper front walls of the two second vertical mounting rods 8 are respectively fixedly installed with first connecting brackets 801, and the two first connecting brackets 801 are respectively installed above the first vertical mounting rods 7 that are close to them; The first end of the thigh support plate 5 is rotatably installed on the inner wall of the two first connecting frames 801, and the first end of the calf support plate 4 is rotatably installed on the second end of the two thigh support plates 5. The calf support plates are used to support the patient's calf and calf respectively. Both lower leg support plates 4 are driven to rotate by a bending mechanism. The two lower leg support plates 4 support the patient's lower legs to bend under the action of the bending mechanism, thereby exercising the patient's knee joint. The degree of bending between the upper and lower legs can be adjusted according to the user's recovery status to operate the subsequent operating mechanism. A second vertical mounting plate 25 is fixedly installed between the upper ends of the two second vertical mounting rods 8, and a horizontal mounting plate 2501 is vertically installed on the lower rear wall of the second vertical mounting plate 25. A stool 11 is fixedly installed on the top wall of the horizontal mounting plate 2501 via the first connecting rod 2502. A backrest 12 is vertically fixed on the rear wall of the stool 11. The stool 11 is used to support the user's torso, allowing the user to exercise while maintaining a seated posture. The backrest 12 is used to support the user's back, improving the user's comfort. Operating mechanisms are movably installed on both sides of the stool 11, and the sliding mechanism is driven by the operating mechanisms. The two L-shaped sliding plates 3 operate through a sliding drive bending mechanism; Several lumbar massage rollers 14 are movably installed on the front wall of the backrest 12. The lumbar massage rollers 14 are all driven by a reciprocating mechanism. The lumbar massage rollers 14 will drive the reciprocating mechanism when the user uses the operating mechanism, thereby causing the lumbar massage rollers 14 to slide up and down on the user's waist. The lumbar massage rollers 14 start to roll when they come into contact with the user's back, thus achieving massage. The reciprocating mechanism is driven to work by the operating mechanism; Flexible air cushions 15 are installed on the outer side of the connection between the two thigh support plates 5 and the adjacent calf support plate 4. The two flexible air cushions 15 are inflated by an air replenishment mechanism; The air supplement mechanism is driven to work by the operating mechanism. Since the knee joint in recovery is extremely fragile, there will be pain in the process of bending the knee joint, especially in the process of straightening the user's calf, the calf is pulled down by gravity to cause pain in the knee joint. Therefore, the flexible air cushion 15 provides a flexible buffer for the knee joint in the process of straightening the user's calf under the action of the air supplement mechanism, thereby reducing the pain; The front walls of the two calf support plates 4 are respectively provided with fixing members 6 for fixing the user's calves.

[0019] The bending mechanism comprises a first rectangular sliding block 26 and a first rectangular through slot 701; The second end outer walls of the two calf support plates 4 are respectively fixedly provided with first connecting shafts, and the outer walls of the two first connecting shafts are respectively rotatably provided with first rectangular sliding blocks 26; The two first vertical installation rods 7 are respectively provided with first rectangular through slots 701, and the two first rectangular sliding blocks 26 are respectively slidably installed in the first rectangular through slots 701 close to them; The two first rectangular sliding blocks 26 are respectively driven to slide by the sliding mechanism, and the two first rectangular sliding blocks 26 are respectively driven to slide by the sliding mechanism. Figure 9 The two first rectangular sliding blocks 26 are respectively driven to slide by the sliding mechanism, and the two first rectangular sliding blocks 26 are respectively driven to slide by the sliding mechanism.

[0020] The sliding mechanism comprises a second connecting shaft 27, a first connecting rod 10, a second rectangular through slot 1001, a reset spring 23, a horizontal movable plate 24, an expansion block 2401, and a first vertical installation plate 2; The lower ends of the horizontal plates of the two L-shaped sliding plates 3 are respectively fixedly provided with vertical plates of T-shaped sliding blocks 301, and the upper ends of the horizontal bottom plate 1 are respectively provided with T-shaped sliding grooves 101 matched with the T-shaped sliding blocks 301; The horizontal plates of the two T-shaped sliding blocks 301 are respectively slidably installed in the T-shaped sliding grooves 101 close to them; The vertical plates of the two L-shaped sliding plates 3 are fixedly provided with the same horizontal movable plate 24 between the rear walls thereof, the middle end of the horizontal movable plate 24 is fixedly provided with the expansion block 2401, the expansion block 2401 is installed between the two L-shaped sliding plates 3, and the expansion block 2401 is slidably installed on the upper end of the horizontal bottom plate 1; The rear wall of the horizontal bottom plate 1 is vertically provided with the first vertical installation plate 2, and the expansion block 2401 and the first vertical installation plate 2 are connected by a plurality of reset springs 23; The first ends of the second connecting shafts 27 are respectively fixedly installed on the outer walls of the two first rectangular sliders 26; The two sides of the rear wall of the stool 11 are respectively fixedly installed with second connecting frames 1101, and the first end of the first connecting rod 10 is rotatably installed on the outer wall of the two second connecting frames 1101 respectively. The lower part of the side wall of each of the two first connecting rods 10 is provided with a second rectangular through groove 1001; The two second connecting shafts 27 are respectively slidably connected through the second rectangular through groove 1001 adjacent to them; The two first links 10 are respectively driven to rotate by the operating mechanism; The two second connecting shafts 27 operate via sliding drive air replenishment mechanisms, see reference. Figure 2 The two first connecting rods 10, driven by the operating mechanism, can rotate up and down around their rotation centers. When the two first connecting rods 10 rotate counterclockwise downwards, they force the second connecting shafts 27 located in the second rectangular through groove 1001 to begin sliding downwards. At this time, the first rectangular sliders 26, fixedly connected to the two second connecting shafts 27, can slide downwards within their respective first rectangular through grooves 701. Since the sliding trajectories of the two L-shaped sliding plates 3 are limited by the cooperation of the T-shaped slider 301 and the T-shaped groove 101, the two first connecting rods 10, during their downward rotation, will, in cooperation with the two second connecting rods 21 (described later with their rotation centers determined later), lift the two first vertical mounting rods 7 respectively. The driving force for sliding to the left is provided, and the two first vertical mounting rods 7 will drive the stool 11 to move to the left during the sliding process. During this process, the leg support plate and the stool 11 move to the left in sync, so the user moves to the left as a whole. The horizontal movable plate 24 and the extension block 2401, which are fixedly installed with the two L-shaped sliding plates 3, also begin to move to the left. During the leftward movement, the extension block 2401 can pull several return springs 23 to begin to stretch. The user can provide different magnitudes of force to the operating mechanism described later to provide different stretching forces to the several return springs 23, thereby adjusting the degree of bending between the legs. The user can also complete a certain amount of aerobic exercise while overcoming the return force of the several return springs 23.

[0021] The air replenishment mechanism includes an outer pipe 17, an air guide hose 16, a piston rod 18, a rectangular movable rod 19, a second connecting rod 21, a third connecting rod 20, a third connecting frame 2101, and a third rectangular through groove 102. The rear of the left and right side walls of the horizontal base plate 1 are respectively fixedly installed with third connecting shafts, and the first ends of the second connecting rods 21 are respectively rotatably installed on the outer walls of the two third connecting shafts. The second ends of the two second connecting rods 21 are respectively rotatably mounted on the outer wall of the second end of the second connecting shaft 27 that is close to them; The middle end of the two second connecting rods 21 is respectively fixedly provided with a third connecting frame 2101, and the first end of the third connecting rod 20 is rotatably arranged in the third connecting frame 2101; A third rectangular through slot 102 is arranged on the side wall of the horizontal bottom plate 1, and the third rectangular through slot 102 is arranged below the two T-shaped sliding grooves 101.

Referring to Figure 2 The second connecting shaft 27 is slid downward along the second rectangular through slot 1001 on the two sides, and in the process of sliding, the second connecting shaft 27 drives the second connecting rod 21 on the two sides to start rotating downward along the center of rotation. In the process of rotating downward, the second connecting rod 21 drives the third connecting rod 20 on the two sides to start deflecting to the left. In the process of deflecting to the left, the third connecting rod 20 pushes the rectangular movable rod 19 to start sliding to the left along the third rectangular through slot 102. In the process of sliding to the left, the rectangular movable rod 19 drives the piston rod 18 to start sliding to the left. In the process of sliding to the left, the piston rod 18 inflates the air in the outer pipe 17. The air flow in the outer pipe 17 passes through the air guide hose 16 to inflate the flexible air cushion 15. The air guide hose 16 finally guides the air flow into the flexible air cushion 15 to inflate the flexible air cushion 15. The flexible air cushion 15 is located in front of the knee joint of the patient. After the patient's legs are stretched out, the flexible air cushion 15 is inflated to provide flexible cushioning for the knee joint of the patient, thereby reducing the pain of the patient during use of the device.
