Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation for sports injuries, and particularly to a rehabilitation training device for sports injuries. Background Art

[0002] Sports injury rehabilitation is a new and emerging interdisciplinary field that combines sports, health, and medicine. It is a new major that combines sports and medicine established to meet the social needs for health and rehabilitation. It mainly studies the relationship between sports and health, and aims to cultivate high-quality rehabilitation treatment technology skills that are comprehensively developed in terms of virtue, intelligence, and technology and meet the needs of the front line of production, construction, management, and service of rehabilitation treatment technology. Sports injury rehabilitation often requires the use of rehabilitation equipment for adjuvant treatment.

[0003] In the prior art, in sports such as basketball, football, and skiing, actions such as sudden stops, changes in direction, or jumps are often used, which can cause excessive valgus or internal rotation of the knee joint. Long-term participation in such sports is likely to cause anterior cruciate ligament injuries and meniscus injuries. In addition, due to the strong competitiveness of sports such as basketball and football, situations such as knee impacts and knees hitting the ground when falling often occur, resulting in patellar fractures. Anterior cruciate ligament, meniscus, and patellar fractures are common sports injuries of the knee joint. When rehabilitating such injuries, it is necessary to straighten the leg while sitting to activate the quadriceps femoris, avoid muscle atrophy after surgery, reduce the pressure on the knee joint, reduce the pressure on the patellofemoral joint, and prevent redislocation. However, currently, there is a lack of such rehabilitation training equipment, and rehabilitation is mainly assisted by family members or rehabilitation coaches, making self-rehabilitation training rather troublesome. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose a rehabilitation training device for sports injuries.

[0005] To achieve the above purpose, the present invention adopts the following technical solution: A rehabilitation training device for sports injuries, including a seat. A counterweight box is fixed to the bottom of the seat. Moving wheels are provided on both sides of the counterweight box. The seat is in a W shape and is successively provided with a push handle, a lumbar support, a seat surface, a leg support, and a footrest from top to bottom. The leg support is rotatably connected to the seat surface. A chute is formed on the surface of the counterweight box. A slider is slidably connected inside the chute. A connecting rod is rotatably connected to the side surface of the slider. A rotating member is rotatably connected to the side surface of the connecting rod. The rotating member is fixed to the leg support. A lead screw is connected to the inner wall of the chute by a bearing. The lead screw passes through the surface of the slider and is threadedly connected to the slider. The lead screw is driven by a driving component.

[0006] Preferably, the drive assembly includes a worm gear, on the surface of which a worm is meshed. Both ends of the worm are connected to bearing seats by bearings. The worm is driven by a worm rotation motor, and both the worm rotation motor and the bearing seats are fixed inside the load-bearing box. The worm rotation motor drives the worm, the worm drives the worm gear to rotate, and the worm gear drives the lead screw to rotate, thereby driving the slider to move downward, so as to cooperate with the connecting rod and the rotating member to slowly raise the leg rest.

[0007] Preferably, the helix angle of the worm is less than the equivalent friction angle between the meshing teeth of the worm and the worm gear. When the helix angle of the worm is less than the equivalent friction angle between the meshing teeth of the worm and the worm gear, the worm and worm gear structure has self-locking property, that is, the worm can drive the worm gear to rotate, but the worm gear cannot drive the worm to rotate, which improves the stability of the leg rest and prevents accidents.

[0008] Preferably, armrests are fixed at both ends of the seat surface. A cup holder block is provided on the inner wall of the armrest. The armrests facilitate the user to hold on, enabling the user to concentrate on the leg-lifting rehabilitation training and providing support to improve safety. At the same time, after a period of rehabilitation training, the user will feel thirsty, so it is necessary to carry a water cup at any time. The cup holder block can conveniently fix the water cup on the seat for easy carrying and taking.

[0009] Preferably, a cup holder chute is formed on the inner wall of the armrest. Cup holder blocks are slidably connected to both ends of the cup holder chute, and a limiting spring is fixed between the side surface of the cup holder block and the side wall of the cup holder chute. The limiting spring improves the adaptability of the cup holder block, enabling it to clamp water cups of different sizes.

[0010] Preferably, ventilation holes are arranged in an array on the surface of the seat surface. After the user undergoes long-term rehabilitation training, the whole body gets hot and sweats, especially in the case of high temperature in summer. Therefore, the ventilation holes can play a good role in heat dissipation and facilitate the rehabilitation training.

[0011] Preferably, an anti-slip rubber pad is adhered to the surface of the leg rest. The anti-slip rubber pad increases the friction between the leg rest and the leg, making the user's leg more stable during the rehabilitation training, preventing the leg from shaking, and improving the training quality.

[0012] Beneficial effects In the prior art, actions such as sudden stops, direction changes, or jumps are commonly used in sports like basketball, football, skiing, etc., which can lead to excessive valgus or internal rotation of the knee joint. Prolonged engagement in such sports is likely to cause anterior cruciate ligament injuries and meniscus injuries. Moreover, due to the relatively high level of confrontation in sports like basketball and football, situations such as knee impacts and knees hitting the ground when falling often occur, resulting in patellar fractures. Anterior cruciate ligament, meniscus, and patellar fractures are common sports injuries of the knee joint. When undergoing rehabilitation training for such injuries, it is necessary to perform sitting straight leg raises to activate the quadriceps femoris, avoid muscle atrophy after surgery, and at the same time reduce the pressure on the knee joint and the patellofemoral joint to prevent redislocation. Currently, rehabilitation training equipment of this kind is still lacking, and rehabilitation is mainly assisted by family members or rehabilitation coaches. It is rather troublesome to carry out rehabilitation training by oneself. To address such problems, the present invention adopts an automatic assisted rehabilitation seat mechanism. The user can sit on the seat, fit the leg to the leg rest, hold the armrest, turn on the worm rotation motor to drive the worm, the worm drives the worm wheel to rotate, the worm wheel drives the lead screw to rotate, thereby driving the slider to move downward, and then cooperating with the connecting rod and the rotating part to slowly raise the leg rest for sitting straight leg raise training, activating the quadriceps femoris, avoiding muscle atrophy after surgery, and at the same time reducing the pressure on the knee joint and the patellofemoral joint to prevent redislocation.

The seat 1 is successively provided with a push handle 4, a lumbar support 3, a seat surface, a leg support 2 and a footrest from top to bottom. Ventilation holes 101 are arranged in an array on the surface of the seat surface. After the user performs rehabilitation training for a long time, the whole body gets hot and sweats, especially in the case of high temperature in summer. Therefore, the ventilation holes 101 can play a good role in heat dissipation and facilitate rehabilitation training. An anti-slip rubber pad 201 is bonded to the surface of the leg support 2. The anti-slip rubber pad 201 increases the friction between the leg support 2 and the leg. The user's leg is more stable during rehabilitation training, preventing the leg from shaking and improving the training quality. The leg support 2 is rotatably connected to the seat surface. A chute is opened on the surface of the counterweight box. A slider 9 is slidably connected inside the chute. A connecting rod 10 is rotatably connected to the side of the slider 9. A rotating member 11 is rotatably connected to the side of the connecting rod 10. The rotating member 11 is fixedly connected to the leg support 2. A lead screw 12 is connected to the inner wall of the chute by a bearing. The lead screw 12 passes through the surface of the slider 9, and the lead screw 12 is threadedly connected to the slider 9. The lead screw 12 is driven by a driving component.

[0018] The driving component includes a worm gear 13. A worm 14 is meshed with the surface of the worm gear 13. Both ends of the worm 14 are connected to bearing seats by bearings. The worm 14 is driven by a worm rotation motor 15, and the worm rotation motor 15 and the bearing seats are both fixed in the inner cavity of the load-bearing box. The worm rotation motor 15 drives the worm 14, the worm 14 drives the worm gear 13 to rotate, the worm gear 13 drives the lead screw 12 to rotate, so as to drive the slider 9 to move downward, thereby cooperating with the connecting rod 10 and the rotating member 11 to slowly lift the leg support 2. The helix angle of the worm 14 is smaller than the equivalent friction angle between the meshing teeth of the worm 14 and the worm gear 13. When the helix angle of the worm 14 is smaller than the equivalent friction angle between the meshing teeth of the worm 14 and the worm gear 13, the worm and worm gear structure has self-locking property, that is, the worm 13 can drive the worm gear 13 to rotate, and the worm gear 13 cannot drive the worm 14 to rotate, improving the stability of the leg support 2 and preventing accidents.

[0019] Armrests 6 are fixed at both ends of the seat surface. A cup holder block 7 is provided on the inner wall of the armrest 6. The armrest 6 facilitates the user to grasp, enabling the user to concentrate on the leg-lifting rehabilitation training and providing support to improve safety. At the same time, after the user performs rehabilitation training for a period of time, the user will feel thirsty. Therefore, it is necessary to carry a water cup at any time. The cup holder block 7 conveniently fixes the water cup on the seat 1, facilitating carrying and taking. A cup holder chute is opened on the inner wall of the armrest 6. Cup holder blocks 7 are slidably connected to both ends of the cup holder chute, and a limit spring 8 is fixed between the side of the cup holder block 7 and the side wall of the cup holder chute. The limit spring 8 improves the adaptability of the cup holder block 7, enabling it to clamp water cups of different sizes.
