Description

Technical Field

[0001] This application relates to the field of medical rehabilitation equipment technology, and in particular to a leg rehabilitation exercise device. Background Technology

[0002] Patients recovering from leg injuries or surgery typically require systematic rehabilitation exercises to restore leg muscle strength, joint mobility, and balance and coordination. These exercises not only accelerate the recovery process but also reduce the occurrence of complications and improve the patient's quality of life. In recent years, with advancements in technology and increased public awareness of health, leg rehabilitation equipment has experienced rapid growth in the market, becoming an important tool in rehabilitation therapy.

[0003] Existing leg rehabilitation equipment employs various design schemes to meet patients' basic needs. Among these, the most common is the simple leg flexion and extension trainer, which uses a mechanical structure to achieve leg flexion and extension movements, primarily for exercising the quadriceps femoris muscles on the front of the thigh. Another commonly used device is the rotational trainer, which uses rotational movements to exercise the internal and external rotator muscles of the calf. Some devices also include fixed resistance training devices, such as elastic ropes, for patients to perform strength training. While these devices alleviate patients' rehabilitation needs to some extent, they still fall short in terms of functional diversity.

[0004] While the aforementioned devices perform well in some aspects, they generally suffer from limitations such as single-function design, lack of personalized adjustment capabilities, and poor comfort. These single-function devices cannot comprehensively cover the exercise needs of all muscle groups in the lower limbs, thus limiting rehabilitation effectiveness. Utility Model Content

[0005] In order to improve the leg rehabilitation exercise effect of the device, this application provides a leg rehabilitation exercise device.

[0006] The leg rehabilitation exercise device provided in this application adopts the following technical solution:

[0007] A leg rehabilitation exercise device includes a base, a seat, and a leg exercise component. The seat is height-adjustable on the base, and a slide rail is provided on the front end of the seat on the base. An exercise base is slidably disposed on the slide rail. The leg exercise component is integrated on the exercise base and includes a flexion-extension exercise unit for realizing leg flexion-extension movements, a rotation exercise unit for simulating leg rotation movements, and a resistance training unit for stretching and exercising the internal muscle groups of the leg.

[0008] By adopting the above-mentioned technical solutions, this leg rehabilitation exercise equipment can achieve multi-directional leg exercises, including not only flexion and extension movements but also rotation and resistance training, effectively enhancing the equipment's functional versatility and rehabilitation effects. Furthermore, the height-adjustable seat design makes it convenient for patients of different heights to use, increasing the equipment's applicability. The design of the sliding rails and exercise base allows the leg exercise components to move flexibly to adapt to different exercise needs, further enhancing the user experience.

[0009] Optionally, the flexion and extension exercise unit includes a rotating shaft, a crank, and a foot pedal. The rotating shaft is mounted on the exercise base, and the crank connects the rotating shaft and the foot pedal and is rotatably engaged with the foot pedal.

[0010] By employing the above-mentioned technical solution, the flexion and extension exercise unit can realize leg flexion and extension movements, effectively exercising the quadriceps muscles on the front of the thigh. The rotating connection design between the foot pedal and the crank allows the user's legs to complete flexion and extension movements in a natural state, increasing the smoothness and comfort of the exercise, thereby improving the effectiveness of rehabilitation training.

[0011] Optionally, the rotating exercise unit includes a rotating sleeve rotatably disposed within the exercise base, a swivel rod rotatably disposed on the exercise base around the rotating sleeve, and a calf fixing bracket rotatably connected to the end of the swivel rod. The rotating sleeve is coaxially sleeved on the rotating shaft, and a connecting rod connects the end of the swivel rod located within the exercise base to the rotating sleeve.

[0012] By adopting the above technical solution, and utilizing the combined design of a rotating sleeve, a swivel rod, and a calf fixation frame, natural leg rotation movements can be effectively simulated, enhancing the strength and flexibility of the calf's internal and external rotator muscles. Simultaneously, the linkage between the swivel rod and the rotating sleeve ensures the stability and safety of the rotational movement, preventing secondary injuries caused by improper movement.

[0013] Optionally, the rotating sleeve is fitted with a torsion spring, one end of which is inserted into the inner wall of the exercise base, and the other end is connected to the end of the rotating rod.

[0014] By employing the above technical solution, the torsion spring provides a constant rebound force when the rotating rod drives the calf fixation frame to rotate, allowing the calf fixation frame to automatically return to its original position, thus improving stability and safety during exercise. Simultaneously, the torsion spring increases the resistance to rotational movement, which helps enhance the strength training effect on the patient's internal and external rotator muscles of the calf.

[0015] Optionally, the rotating rod has an adjustment groove coaxially formed inside. The resistance training unit includes a tension block slidably disposed in the adjustment groove, an end block rotatably connected to the calf fixation frame, a guide rod connecting the tension block and the end block, and a tension spring connecting the inner wall of the tension block adjustment groove. The guide rod slidably passes through the rotating rod, and the tension spring is located on the side of the tension block away from the calf fixation frame.

[0016] By adopting the above technical solution, the rotating rod not only provides a rotational exercise effect, but also a resistance stretching effect. Under the action of the tension block and the tension spring, the user stretches the calf fixation frame away from the exercise base, thereby achieving a stretching exercise effect on the muscle groups inside the leg.

[0017] Optionally, an adjusting block is rotatably provided in the adjusting groove via a thread, and a tension spring is connected between the adjusting block and the tension block. The tension block has multiple guide posts distributed circumferentially on the side facing the adjusting block. The multiple guide posts are all arranged parallel to the adjusting groove and are slidably inserted into the adjusting block.

[0018] By adopting the above technical solution, under the synchronous drive of the guide post, the rotating end block can synchronously rotate the adjusting block, thereby adjusting the position of the adjusting block under the drive of the thread. This allows users to adjust the tension of the tension spring according to actual needs, thereby changing the resistance and achieving personalized strength training.

[0019] Optionally, the slide rail is provided with a number of positioning holes along its own length direction, and the exercise base is provided with a number of limiting holes, with a limiting pin inserted between each limiting hole and the corresponding positioning hole.

[0020] By adopting the above technical solution, the precise position of the exercise base on the slide rail can be fixed, ensuring the stability and safety of users exercising in different positions, while facilitating quick adjustment of the exercise position and improving the flexibility and convenience of the equipment.

[0021] Optionally, handles are provided on both sides of the seat.

[0022] By adopting the above technical solution, the handles set on both sides of the seat can provide stable support for patients when using the equipment, increase safety, and at the same time facilitate patients to adjust their body position, improving comfort and convenience.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This leg rehabilitation exercise equipment enables multi-directional leg exercises, including not only flexion and extension movements but also rotation and resistance training, effectively enhancing the equipment's functional versatility and rehabilitation effects. Furthermore, the height-adjustable seat design allows for convenient use by patients of different heights, expanding the equipment's applicability. The design of the sliding rails and exercise base allows for flexible movement of the leg exercise components to adapt to different exercise needs, further enhancing the user experience.

[0025] 2. The flexion and extension exercise unit enables leg flexion and extension movements, effectively exercising the quadriceps muscles on the front of the thigh. The rotating connection design between the foot pedal and the crank allows the user's legs to complete flexion and extension movements in a natural state, increasing the smoothness and comfort of the exercise, thereby improving the effectiveness of rehabilitation training;

[0026] 3. The combined design of the rotating sleeve, rotating rod, and calf fixation frame effectively simulates natural leg rotation movements, enhancing the strength and flexibility of the calf's internal and external rotator muscles. Simultaneously, the linkage between the rotating rod and the rotating sleeve ensures the stability and safety of the rotational movement, preventing secondary injuries caused by improper movement.
