[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0025] Please see Figures 1-5 This utility model provides a technical solution: a sports rehabilitation training device, including a base 10, a support frame 11 slidably connected to the top of the base 10, and a knee pad 12 slidably connected to one side of the base 10; two locking rods 13, which are rotatably connected to the adjacent ends of the knee pad 12, and a pull rod 131 rotatably connected between the top ends of the two locking rods 13; and an adjustment module 16, which is disposed inside the base 10 and is used to adjust the support frame 11 and the knee pad 12.
[0026] In practice, the rehabilitation personnel kneel on one leg on the protective pad 121 and squat on the other leg for support. They rest their elbow on the protective pad 111 for auxiliary support. One hand is fixed by the forearm against the auxiliary plate 112. Depending on the user's size, the screw 162 can be rotated by manually turning the control dial 163 to adjust the height of the support frame 11. Then, the distance of the knee pad 12 can be adjusted appropriately to accommodate rehabilitation personnel of different sizes. The other hand holds the grip bar 141 and pulls the pull bar 131. By pulling the grip bar 141, the pull bar 131 is rotated, thereby pulling the lower leg for rehabilitation training. Compared with rehabilitation with the help of others, this method saves more manpower and makes it easier to control the force, avoiding overstretching and damage to ligaments.
[0027] The base 10 provides lateral sliding limit to the limiting frame 15, facilitating the adjustment of the limiting frame 15's position. This allows the support frame 151 to support either leg. The limiting frame 15 provides vertical sliding limit to the support frame 151, and the damper 152, in conjunction with the spring 153, provides shock absorption. This allows the support frame 151 to have a small range of movement, resulting in more comfortable support for the thigh and support for thighs of different heights, making it more adaptable.
[0028] See Figures 1-2 The top of the support frame 11 is fixed with a protective pad 111 and an auxiliary plate 112, and the top of the knee pad 12 is fixed with a protective pad 121.
[0029] The bottom of the knee pad 12 is rotatably connected to multiple rollers 122 at both ends.
[0030] In practice, the use of protective pad 111 and protective pad 121 improves the feel of the support frame 11 and the top of the knee pad 12, reduces bumps, and facilitates rehabilitation training. When the person places their elbow on the top of protective pad 111, one hand uses the forearm to press against the auxiliary plate 112 for fixation, while the other hand holds the handle 141 to pull the lever 131, making operation more convenient. The roller 122 reduces friction between the knee pad 12 and the ground, making it easier to adjust the position of the knee pad 12.
[0031] See Figure 1 Both ends of the support frame 11 are rotatably connected to the second clamp rod 14, and the top ends of the two clamp rods 14 are rotatably connected to the grip rod 141. A nylon rope 132 is fixed to the outer wall of the first clamp rod 13, and one end of the nylon rope 132 is fixed to the adjacent second clamp rod 14.
[0032] In practice, two levers 13 limit the rotation of the pull rod 131, and lever 14 limits the rotation of the grip bar 141. A nylon rope 132 connects the pull rod 131 and the grip bar 141. The rehabilitation person kneels on the protective pad 121 with one knee and pulls the grip bar 141 to rotate the pull rod 131, thereby pulling the lower leg for rehabilitation training. Compared with rehabilitation with the help of others, this method saves manpower and allows for better control of the force, avoiding overstretching and damage to the ligaments.
[0033] See Figure 2 A limit frame 15 is slidably connected to the inner wall of the base 10. A support frame 151 is slidably connected to the top of the limit frame 15. Two dampers 152 are fixedly connected to the inner bottom surface of the limit frame 15. The telescopic end of the damper 152 is fixedly connected to the support frame 151. A spring 153 is fixedly connected between the damper 152 and the support frame 151.
[0034] In practice, the base 10 slides and limits the limit frame 15 laterally, making it easy to adjust the position of the limit frame 15. This allows the support frame 151 to support any leg. The limit frame 15 slides and limits the support frame 151 vertically, and the damper 152 works in conjunction with the spring 153 to reduce shock. This allows the support frame 151 to have a small range of movement, making the support for the thigh more comfortable and able to support thighs of different heights, thus making it more adaptable.
[0035] See Figures 3-5 The control module 16 includes multiple slide rods 161. The top of the slide rod 161 is fixedly connected to the support frame 11, and the bottom of the slide rod 161 passes through the base 10 and is slidably connected thereto. The support frame 11 is rotatably connected to a lead screw 162, which passes through the base 10 and is screwed thereto. A control disc 163 is fixedly sleeved on the outer wall of the lead screw 162.
[0036] Multiple sliding rods 164 are fixedly connected to the outer wall of the knee pad 12. The sliding rods 164 pass through the base 10 and are slidably connected to it. One end of one of the sliding rods 164 is slidably connected to a locking block 165. A spring 166 is fixedly connected between the locking block 165 and the sliding rod 164. Multiple slots 167 are equidistantly provided on the outer wall of the base 10. The locking block 165 can be movably engaged with the adjacent slot 167.
[0037] In practice, the vertical sliding limit of the support frame 11 is achieved by the limiting of the base 10 and the two sliding rods 161. The screw 162 can be rotated by manually rotating the control dial 163. The support frame 11 is moved and adjusted in the vertical direction by the transmission between the screw 162 and the base 10, thereby adjusting the height of the support frame 11 to facilitate support for the elbows of rehabilitation personnel of different sizes.
[0038] The knee pad 12 is laterally slidably limited by the cooperation of two sliding rods 164. The locking block 165 is manually pulled out from the slot 167, and the position of the knee pad 12 can be adjusted to accommodate the leg position of rehabilitation personnel of different sizes. After the position of the knee pad 12 is adjusted, the locking block 165 is released. Under the reset action of the spring 166, the locking block 165 is locked into the adjacent slot 167, thereby quickly limiting the position of the knee pad 12.
[0039] Working principle: When using this device, the rehabilitation person kneels on one leg on protective pad 2 121, and squats on the other leg for support. The elbow is placed on protective pad 111 for auxiliary support. One hand is fixed by the forearm against the auxiliary plate 112. Depending on the user's body size, the screw 162 can be rotated by manually turning the control dial 163 to adjust the height of the support frame 11. Then, the distance of the knee pad 12 can be adjusted appropriately to accommodate rehabilitation personnel of different body sizes. The other hand holds the grip bar 141 and pulls the pull bar 131. By pulling the grip bar 141, the pull bar 131 is rotated, thereby pulling the lower leg for rehabilitation training. Compared with rehabilitation with the help of others, this method saves more manpower and makes it easier to control the force, avoiding overstretching and damage to ligaments.
[0040] The base 10 provides lateral sliding limit to the limiting frame 15, facilitating the adjustment of the limiting frame 15's position. This allows the support frame 151 to support either leg. The limiting frame 15 provides vertical sliding limit to the support frame 151, and the damper 152, in conjunction with the spring 153, provides shock absorption. This allows the support frame 151 to have a small range of movement, resulting in more comfortable support for the thigh and support for thighs of different heights, making it more adaptable.
