Description

Technical Field

[0001] This utility model relates to the field of rehabilitation medical device technology, specifically a rehabilitation bracket for lower limb rehabilitation. Background Technology

[0002] Patients with lower limb muscle dysfunction, stroke, or cerebrovascular disease who have difficulty moving their lower limbs will experience a decline in joint flexibility if they do not receive effective treatment for a long time, which will seriously affect their lives. Early intervention with rehabilitation training can effectively reduce the risks of muscle atrophy and loss of joint mobility. In addition, rehabilitation training after surgery can improve the self-care ability of patients with lower limb injuries and alleviate the burden of subsequent family treatment.

[0003] Most common lower limb rehabilitation training devices use electric push rods to power the legs to move. Although this method can achieve the purpose of joint movement, it is a passive exercise due to external force, and therefore cannot be exercised by oneself. Only by using self-exercise can the rehabilitation time be accelerated. The rehabilitation time is longer when using the passive method. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a rehabilitation bracket for lower limb rehabilitation, which solves the problem of not being able to receive corresponding exercise.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rehabilitation bracket for lower limb rehabilitation, comprising a chassis, a cylinder fixedly connected to the middle of the upper surface of the chassis, a first support plate fixedly connected to the output end of the cylinder, two symmetrical sleeves fixedly connected to the upper surface of the first support plate, a first push rod and a second support plate slidably connected inside each sleeve, a foot pedal fixedly connected to the upper end of the two first push rods, a limit frame fixedly connected between the two adjacent sides of the two second support plates, a U-shaped support frame fixedly connected to the middle of the upper surface of the first support plate, a rotating shaft rotatably connected between the front and rear side walls of the support frame, and the rear end of the rotating shaft passing through the support frame, a toggle plate fixedly connected to the middle of the outer surface of the rotating shaft, and the toggle plate being located directly below the support frame.

[0006] As a further description of the above technical solution, each of the second support plates is fixedly connected to a first spring between itself and the first push rods that are close to each other, and each first spring is in its initial state, and can play a certain supporting role under the action of the first spring.

[0007] As a further description of the above technical solution, two symmetrical sliding grooves are provided on the back of the chassis. A second push rod is slidably connected inside each sliding groove. A first constraint plate is fixedly connected to the rear end of the two second push rods. A second constraint plate is fixedly connected to the back of the chassis, which enables the first constraint plate to move along the trajectory of the sliding groove to avoid misalignment. At the same time, the second constraint plate can also play a certain supporting role, making the whole more stable.

[0008] As a further description of the above technical solution, each of the second push rods is fixedly connected to a second spring between itself and the adjacent slide groove, and each second spring is in a stretched state. Under the action of the second spring, the first constraint plate can be brought close to the second constraint plate, thereby fixing the position of the chair and making it more convenient to use.

[0009] As a further description of the above technical solution, two symmetrical positioning rods are fixedly connected to the upper surface of the chassis, and each positioning rod penetrates the bottom surface of the foot pedal. A support rod is sleeved at the upper end of each positioning rod. Under the action of the positioning rods, the foot pedal can be raised or lowered smoothly to avoid misalignment.

[0010] As a further description of the above technical solution, a third spring is fixedly connected between each positioning rod and the foot pedal, and each third spring is in a stretched state. Under the action of the third spring, it can effectively prevent the situation from falling off.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This lower limb rehabilitation support frame, through the cooperation of the support frame, rotating shaft, and actuating plate, can freely adjust the distance between itself and the first push rod, so that the first spring between them is compressed or reset. When the pressure is large, the first push rod can rise smoothly; when the pressure is small, the second push rod falls accordingly, so that the foot pedal can rise and then fall, causing the pushing force to fluctuate. When the pushing force is small, it can only be lifted by itself, thus achieving a certain exercise purpose and solving the problem of not being able to receive the corresponding exercise.

[0013] 2. This rehabilitation bracket for lower limb rehabilitation, through the cooperation of the second push rod, the slide groove and the second spring, can bring the first constraint plate close to the second constraint plate. Under the action of elasticity, the position of the chair can be fixed, making it more convenient to use. Through the cooperation of the positioning rod and the support rod, the support rod can be rotated freely, thereby allowing the angle of the support rod to be freely adjusted, thus adapting to different users.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a rehabilitation bracket for lower limb rehabilitation, including a chassis 1. Two symmetrical support legs are fixedly connected to the bottom surface of the chassis 1, and the lower ends of the support legs and the bottom surface of the second constraint plate 16 are on the same horizontal plane, thereby making the whole more stable. A cylinder 2 is fixedly connected to the middle of the upper surface of the chassis 1. A first support plate 3 is fixedly connected to the output end of the cylinder 2. Two symmetrical sleeves 4 are fixedly connected to the upper surface of the first support plate 3. A first push rod 5 and a second support plate 6 are slidably connected inside each sleeve 4. A first spring 12 is fixedly connected between each first support plate 3 and its adjacent first push rod 5, and each first spring 12 is in the initial state. Under the action of the first spring 12, it can play a certain supporting role.

[0021] Foot pedals 7 are fixedly connected to the upper ends of the two first push rods 5. Two symmetrical grooves are formed on the upper surface of the foot pedals 7. Multiple rectangularly distributed anti-slip blocks are fixedly connected to the bottom wall of each groove. The grooves make it easier to place the foot, and the anti-slip blocks increase friction to prevent slippage. A limit frame 8 is fixedly connected between the adjacent sides of the two second support plates 6. A U-shaped support frame 9 is fixedly connected to the middle of the upper surface of the first support plate 3. A rotating shaft 10 is rotatably connected between the front and rear side walls of the support frame 9, and the rear end of the rotating shaft 10 passes through the support frame 9. A toggle plate 11 is fixedly connected to the middle of the outer surface of the rotating shaft 10, and the toggle plate 11 is located at the center of the support frame 9. Below, a motor is fixedly connected to the rear of the upper surface of the first support plate 3, and the output shaft of the motor is fixedly connected to the rear end of the rotating shaft 10. Under the action of the motor, the rotating shaft 10 can drive the actuating plate 11 to rotate, thereby achieving the purpose of power transmission. Two symmetrical sliding grooves 13 are opened on the back of the chassis 1. A second push rod 14 is slidably connected inside each sliding groove 13. The rear ends of the two second push rods 14 are fixedly connected to a first constraint plate 15. A second constraint plate 16 is fixedly connected to the back of the chassis 1, which enables the first constraint plate 15 to move along the trajectory of the sliding groove 13 to avoid misalignment. At the same time, the second constraint plate 16 can also play a certain supporting role, making the whole more stable.

[0022] Each second push rod 14 is fixedly connected to a second spring 17 with its adjacent sliding groove 13, and each second spring 17 is in a stretched state. Under the action of the second spring 17, the first constraint plate 15 can be brought closer to the second constraint plate 16, thereby fixing the position of the chair and making it more convenient to use. Two symmetrical positioning rods 18 are fixedly connected to the upper surface of the chassis 1, and each positioning rod 18 penetrates the bottom surface of the foot pedal 7. A support rod 19 is sleeved on the upper end of each positioning rod 18. Under the action of the positioning rod 18, the foot pedal 7 can be raised or lowered smoothly to avoid misalignment. Each positioning rod 18 and the foot pedal 7 are fixedly connected to a third spring 20, and each third spring 20 is in a stretched state. Under the action of the third spring 20, it can effectively prevent the foot pedal from falling off.

[0023] Working principle: Both cylinder 2 and the motor are electrically connected to the municipal power supply. Pulling the second push rod 14 causes the first constraint plate 15 to move backward, simultaneously stretching the second spring 17 to generate a restoring force. A suitable seat is placed between the first constraint plate 15 and the second constraint plate 16. Under the action of the spring force, the seat is compressed and positioned. The injured person is placed on the seat, with their feet placed on the surface of the foot pedal 7, so that their feet are positioned in the groove. The two support rods 19 are moved to a suitable angle for easier use. Simultaneously, the motor and cylinder 2 are started. Under the action of the motor, the rotating shaft 10 is driven to rotate the actuating plate 11. Under the compression action, the limiting frame 8 is raised. Under the action of the second support plate 6, the... The reduced distance between the second support plate 6 and the first push rod 5 compresses the first spring 12, thereby pushing the foot pedal 7 upward. When the compressive force disappears, the foot pedal 7 can be pushed downward. Simultaneously, under the action of the cylinder 2, the first support plate 3 can be driven upward, allowing the sleeve 4 to rise smoothly. When the first spring 12 is compressed, it can push the first push rod 5 upward, thereby raising the foot pedal 7, allowing the foot to rise and the joint to move. When the first spring 12 is relaxed, the corresponding foot pedal 7 will descend a certain distance, requiring the injured person to lift their foot independently, thus achieving the purpose of exercise. Subsequently, the foot pedal 7 will return to the position of the foot plate, providing support for the foot and avoiding prolonged exertion and over-exercise.
