AI Technical Summary
Existing rehabilitation devices for lower limb dysfunction have simple pedal designs and lack the function of fixing the patient's feet. This can lead to foot slippage or instability when muscle strength is weak or balance is poor, affecting the effectiveness of rehabilitation training and increasing the risk of injury.
Four square blocks are set inside the pedal, and Velcro is installed on the top. The Velcro is used to fix the foot, and the position of the blocks can be adjusted by adjusting the structure to accommodate different foot shapes. Stable fixation is achieved by the threaded connection between the internal threaded cylinder and the threaded rod.
It effectively prevents the foot from slipping or becoming unstable during rehabilitation training, improving the safety and stability of rehabilitation training and adapting to the fixation needs of different foot sizes.

Technical Field
[0001] This utility model relates to the field of rehabilitation technology, specifically to a rehabilitation device for lower limb dysfunction with adjustable angle. Background Technology
[0002] Lower limb dysfunction is a common sequela of various diseases and injuries, severely impacting patients' ability to live independently and their motor function. This dysfunction can be caused by a variety of factors, including but not limited to stroke, spinal cord injury, fractures, neuromuscular diseases, and muscle atrophy due to prolonged bed rest. These patients face numerous challenges during rehabilitation, the most important of which is how to restore lower limb muscle strength, joint mobility, and balance through scientific and appropriate rehabilitation training. Rehabilitation training is crucial for patients with lower limb dysfunction; it not only helps improve limb function but also enhances patients' self-confidence and self-care ability, thereby improving their quality of life. However, the effectiveness of rehabilitation training largely depends on whether the rehabilitation equipment used can meet the individualized rehabilitation needs of the patient.
[0003] While existing rehabilitation devices for lower limb dysfunction can meet the basic training needs of patients to a certain extent, they still have many shortcomings. For example, most rehabilitation devices have simple pedal designs and do not have a foot fixation function. When patients with lower limb dysfunction have weakened muscle strength or poor balance, their feet are prone to slipping or becoming unstable on the pedals. This not only affects the effectiveness of rehabilitation training but may also increase the risk of injury to patients. Utility Model Content
[0004] The purpose of this invention is to provide a rehabilitation device for lower limb dysfunction with adjustable angle, in order to solve the problem that most rehabilitation devices proposed in the prior art have a simple pedal design and do not have a fixation function for the patient's feet. When patients with lower limb dysfunction have weakened muscle strength or poor balance, their feet are prone to slipping or becoming unstable on the pedal, which not only affects the effect of rehabilitation training, but may also increase the risk of injury to the patient.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rehabilitation device for lower limb dysfunction with adjustable angle, comprising a base frame and a computer operating unit. The computer operating unit is installed on the top of the base frame. An adjustable support is provided on the top of the base frame. A body support is provided on the top of the adjustable support. A joint protection part is provided on one side of the body support. A foot support is provided on one side of the joint protection part. The foot support includes a foot pedal. Two blocks are provided on each side of the foot pedal. An adjustment structure is provided between the four blocks and the foot pedal. Velcro fastener 1 is installed on the top of two of the blocks, and Velcro 2 is installed on the top of the other two blocks.
[0006] Preferably, the adjustment structure includes two elongated slots, which are respectively opened on both sides inside the pedal. The inner sides of the two elongated slots are formed with mounting grooves, and the tops of the two mounting grooves are formed with through grooves.
[0007] Preferably, the adjustment structure further includes four threaded rods, each fixedly connected to one side of the block. An internally threaded cylinder is threadedly connected to the outer side of each threaded rod. One end of the internally threaded cylinder passes through a long groove and extends into the mounting groove. A hollow slider is rotatably connected to the outer side of the internally threaded cylinder. The hollow slider is located inside the mounting groove and slidably connected to the foot pedal. A worm gear is provided inside the hollow slider. The worm gear is fixedly connected to the outer side of the internally threaded cylinder. A worm is meshed with the outer side of the worm gear. The top end of the worm passes through a through groove, and a handle is installed at the top end of the worm. The through groove allows the worm to pass through, facilitating unrestricted movement of the hollow slider.
[0008] Preferably, the outer side of the internally threaded cylinder is provided with a telescopic rod, one end of which is fixedly connected to the block, the other end of which passes through the long groove, and the other end of which passes through the hollow slider and is fixedly connected to the hollow slider.
[0009] Preferably, a threaded rod is fixedly connected to the outside of the hollow slider, and an internally threaded cylinder is threadedly connected to the outside of the threaded rod. One end of the internally threaded cylinder is rotatably connected to the pedal, and a connecting block is rotatably connected to the outside of the other end of the internally threaded cylinder. The bottom end of the connecting block is fixedly connected to the pedal. The setting of the connecting block improves the rotational stability of the internally threaded cylinder.
[0010] Preferably, a worm gear two is fixedly connected to the outer side of the internally threaded cylinder two, and a worm two is meshed with the outer side of the worm gear two. One end of the worm two is rotatably connected to the pedal, and the other end of the worm two passes through the inner side of the mounting groove and extends to the outer side of the pedal. A throttle handle two is installed on one end of the worm two.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This application uses four squares on both sides of the inside of the foot pedal. Two of the squares have Velcro closure 1 on top, and the other two squares have Velcro closure 2 on top. During use, the patient places their foot on the foot pedal, and the Velcro closure 1 and Velcro closure 2 securely fix the patient's foot on the foot pedal. This effectively prevents the patient's foot from slipping or becoming unstable on the foot pedal due to weakened muscle strength or poor balance during rehabilitation training, thus ensuring the smooth progress of rehabilitation training and improving the safety of rehabilitation training.
[0013] 2. This application uses a threaded connection between the internal threaded cylinder 2 and the threaded rod 2. The threaded rod 2 can drive the hollow slider to slide inside the mounting groove. The hollow slider can adjust the movement of the block through the internal threaded cylinder 1, the threaded rod 1 and the telescopic rod 1. This structural design allows the position of the block to be adjusted so that multiple blocks can contact the sides of feet of different sizes. With the help of Velcro 1 and Velcro 2, the stability of fixing feet of different sizes can be improved. Attached Figure Description
