Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, and in particular to an adjustable knee joint exercise rehabilitation device. Background Technology

[0002] The knee joint is one of the largest and most complex joints in the human body, bearing the brunt of vital functions such as walking, running, and jumping. Therefore, knee injuries not only affect an individual's daily activities but can also lead to long-term physical decline. With the development of medical technology, an increasing number of rehabilitation devices have been designed to help patients restore knee joint function. Among these, wall sliding exercises are an effective rehabilitation method. Patients lie supine with their feet against a wall and slowly slide down to the maximum knee flexion angle. However, wall sliding exercises have some limitations. First, they require a wall as a support point, and training on a white wall can easily get the wall dirty, making it difficult to find a suitable training location. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable knee joint exercise rehabilitation device. By setting a rotatable rotating plate, a support mechanism and a limiting mechanism to fix the rotating plate when it is rotated to a vertical position, a device that can perform wall sliding training is formed, which is convenient for patients to train.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An adjustable knee joint rehabilitation device includes a support plate, a rotating plate rotatably connected to the left end of the support plate, the rotating plate being foldable onto the upper end of the support plate, a limiting mechanism on the support plate that cooperates with the rotating plate for fixing the rotating plate when it is horizontal, and a support mechanism on the rotating plate that cooperates with the limiting mechanism for fixing the rotating plate when it is rotated to a vertical position.

[0006] By adopting the above technical solution, when the rotating plate is fixed by the limiting mechanism, the rotating plate remains in a horizontal state, allowing for passive knee flexion training for rehabilitation. When the rotating plate is rotated to a vertical state and fixed by the limiting and supporting mechanisms, wall sliding training can be performed.

[0007] A further feature of this invention is as follows: a support leg is provided at the lower left side of the rotating plate, a first connecting block is provided at the lower end of the support leg, and a mounting groove with an open left end is provided at the lower end of the support plate. The limiting mechanism includes a sliding rod, a support rod, a first fixing knob, and a second fixing knob. Two sliding rods are provided and inserted into the mounting groove with their left and right orientations respectively. The left ends of the two sliding rods extend out of the mounting groove and are connected to both ends of the support rod. The first fixing knob is provided on the side of the support plate and is used to fix the sliding rod. A slot is provided at the upper end of the support rod, and the slot is used to cooperate with the first connecting block. The second fixing knob is provided on both sides of the support rod and is used to fix the first connecting block.

[0008] By adopting the above technical solution, the limiting mechanism secures the support rod and the first connecting block by sliding out the slide bar and fixing them with the second fixing knob, ensuring the stability of the rotating plate in a horizontal state. Furthermore, it facilitates the storage of the limiting mechanism without affecting the folding and storage of the rotating plate.

[0009] A further feature of this invention is that the support mechanism includes two telescopic rods, a third fixing knob, and a second connecting block. One end of each of the two telescopic rods is rotatably connected to the lower end of the rotating plate and to the side near the support leg. The two telescopic rods are symmetrically arranged front and back. The third fixing knob is located on the telescopic rods. The other ends of the two telescopic rods are respectively connected to the second connecting block. When the rotating plate rotates to a vertical position, the telescopic rods are rotated to engage the second connecting block with the slot and fix it with the second fixing knob.

[0010] By adopting the above technical solution, the limiting mechanism is first unfolded, and when the rotating plate is rotated to a vertical position, the second connecting block is connected and fixed to the slot by rotating the telescopic rod and adjusting the length of the telescopic rod, so that the rotating plate remains in a vertical position, which facilitates the completion of wall sliding training.

[0011] A further feature of this invention is that the upper end of the rotating plate has two symmetrical grooves, each groove being equipped with a fixing component that can slide left and right, the fixing component being used to fix the patient's foot.

[0012] By adopting the above technical solution, the feet are fixed by a fixing component, limiting the sliding direction of the feet, ensuring the training effect, and facilitating wall sliding training.

[0013] A further feature of this invention is that: the groove has rolling grooves on both its front and rear sides; the fixing assembly includes a foot plate, a movable block, rollers, a first fixing belt, a second fixing belt, and connecting belts; the foot plate is positioned above the rotating plate; the movable block is positioned at the lower end of the foot plate and inserted into the groove; two rollers are provided and positioned on the front and rear sides of the movable block, and are positioned within the rolling grooves, with the rollers rolling in cooperation with the rolling grooves; the first fixing belt is positioned at the upper end of the foot plate, with both ends connected to the front and rear ends of the foot plate respectively; the lower end of the second fixing belt is connected to the right end of the foot plate; two connecting belts are provided and are respectively connected to the front and rear sides of the upper end of the second fixing belt; the other ends of the two connecting belts are detachably connected to the upper end of the first fixing belt via Velcro.

[0014] By adopting the above technical solution, the patient's foot can be more effectively stabilized.

[0015] A further feature of this invention is that the bottom of the groove has multiple positioning holes spaced evenly from left to right. The fixing assembly also includes a spring, a slider, and a positioning pin. The slider is located on the right side of the movable block and is slidably connected to the groove. The slider can slide left and right. The spring is located in the groove, with one end connected to the slider and the other end connected to the movable block. The positioning pin is vertically inserted into the slider and can be inserted into the positioning hole.

[0016] By adopting the above technical solution, it is convenient to increase resistance during wall sliding training. The position of the slider can be changed to adjust the position of the spring, thereby changing the magnitude of the resistance.

[0017] A further feature of this invention is that a first flexible pad is provided at the upper end of the support plate.

[0018] By adopting the above technical solutions, the comfort of sitting on the support board can be improved.

[0019] A further feature of this invention is that a second flexible pad is provided at the upper end of the rotating plate.

[0020] By adopting the above technical solution, the comfort of placing both feet on the rotating plate is improved.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0036] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] An example is an adjustable knee joint rehabilitation device, such as... Figures 1 to 7 As shown, the device includes a support plate 1, with a rotating plate 2 rotatably connected to the left end of the support plate 1. The rotating plate 2 can be folded onto the upper end of the support plate 1. The support plate 1 has a limiting mechanism 3 that works in conjunction with the rotating plate 2, used to fix the rotating plate 2 when it is horizontal. The rotating plate 2 has a support mechanism 4 that works in conjunction with the limiting mechanism 3, used to fix the rotating plate 2 when it is rotated to a vertical position. The limiting mechanism 3 and the support mechanism 4 can fix the rotating plate 2 in both horizontal and vertical positions. In the horizontal position, both the rotating plate 2 and the support plate 1 are horizontal, facilitating passive knee flexion training. In the vertical position, the rotating plate 2 and the support plate 1 are perpendicular to each other, allowing for wall sliding training. A first flexible pad 7 is provided at the upper end of the support plate 1, and a second flexible pad 8 is provided at the upper end of the rotating plate 2. This improves comfort during use. Of course, the first flexible pad 7 and the second flexible pad 8 do not affect the folding of the rotating plate 2 onto the upper end of the support plate 1.

[0038] A support leg 5 is provided at the lower left side of the rotating plate 2. A first connecting block 51 is provided at the lower end of the support leg 5. A mounting groove 11 with an open left end is provided at the lower end of the support plate 1. The limiting mechanism 3 includes a sliding rod 31, a support rod 32, a first fixing knob 33, and a second fixing knob 34. Two sliding rods 31 are provided and are inserted into the mounting groove 11 with their left and right sides facing each other. The left ends of the two sliding rods 31 extend out of the mounting groove 11 and are connected to the two ends of the support rod 32. The first fixing knob 33 is provided on the side of the support plate 1 and is used to fix the sliding rod 31. A slot 35 is provided at the upper end of the support rod 32. The slot 35 is used to cooperate with the first connecting block 51. The second fixing knob 34 is provided on both sides of the support rod 32 and is used to fix the first connecting block 51. The support leg 5 and support rod 32 work together to keep the rotating plate 2 in a horizontal position. After all, the rotating plate 2 needs to rotate to the upper end of the support plate 1, and the connection between the rotating plate 2 and the support plate 1 needs to be higher than the support plate 1. Of course, this also facilitates the installation of the limiting mechanism 3 and the support mechanism 4. By extending the slide rod 31 and fixing it with the first fixing knob 33, and then rotating the rotating plate 2, the first connecting block 51 is rotated into the slot 35 and fixed with the second fixing knob 34, thus fixing the rotating plate 2.

[0039] The support mechanism 4 includes two telescopic rods 41, a third fixing knob 42, and a second connecting block 43. One end of each telescopic rod 41 is rotatably connected to the lower end of the rotating plate 2 and near the support leg 5. The two telescopic rods 41 are symmetrically arranged front and back. The third fixing knob 42 is located on the telescopic rods 41. The other ends of the two telescopic rods 41 are respectively connected to the second connecting block 43. When the rotating plate 2 rotates to a vertical position, the telescopic rods 41 are rotated to engage the second connecting block 43 with the slot 35 and are fixed with the second fixing knob 34. In use, the limiting mechanism 3 is unfolded, the rotating plate 2 is rotated to a vertical position, the telescopic rods 41 are rotated, and the length of the telescopic rods 41 is adjusted. The second connecting block 43 is inserted into the slot 35 and fixed with the second fixing knob 34, thus supporting the rotating plate 2 in a vertical position.

[0040] Two symmetrical grooves 21 are provided at the upper end of the rotating plate 2. Each groove 21 is provided with a fixing component 6 that can slide left and right. The fixing component 6 is used to fix the patient's feet. The groove 21 has rolling grooves 22 on both the front and rear sides. The fixing component 6 includes a foot plate 61, a moving block 62, a roller 63, a first fixing belt 64, a second fixing belt 65, and a connecting belt 66. The foot plate 61 is located above the rotating plate 2. The moving block 62 is located at the lower end of the foot plate 61 and is inserted into the groove 21. There are two rollers 63 located on the front and rear sides of the moving block 62 and are located in the rolling grooves 22. The rollers 63 roll in cooperation with the rolling grooves 22. The first fixing belt 64 is located at the upper end of the foot plate 61 and its two ends are respectively connected to the front and rear ends of the foot plate 61. The lower end of the second fixing belt 65 is connected to the right end of the foot plate 61. There are two connecting belts 66 and they are respectively connected to the front and rear sides of the upper end of the second fixing belt 65. The other ends of the two connecting belts 66 are detachably connected to the upper end of the first fixing belt 64 by Velcro. The fixation component 6 secures the patient's feet, limiting their sliding motion and ensuring the effectiveness of the training. It is also more convenient than direct sliding. The fixation method involves placing the foot on the footplate 61, then moving the foot forward to engage with the first fixation strap 64. The second fixation strap 65 wraps around the heel from the front and is tightened from both sides by two connecting straps 66, securing it to the first fixation strap 64, thereby fixing the foot to the footplate 61.

[0041] The bottom of the groove 21 has multiple positioning holes 23 evenly spaced from left to right. The fixing component 6 also includes a spring 67, a slider 68, and a positioning pin 69. The slider 68 is located on the right side of the moving block 62 and is slidably connected to the groove 21. The slider 68 can slide left and right. The spring 67 is located inside the groove 21, with one end connected to the slider 68 and the other end connected to the moving block 62. The positioning pin 69 is vertically inserted into the slider 68 and can be inserted into the positioning hole 23. The spring 67 can increase the resistance during training, and changing the position of the slider 68 can also change the magnitude of the resistance, thus improving the training effect. Of course, when installing the spring 67, it is necessary to ensure that the spring 67 will not pop out when compressed.

[0042] Instructions for use: 1. Passive knee flexion, suitable for the acute phase. Set the rotating plate 2 to the horizontal position. The patient sits on the support plate 1, and the affected limb is fixed on the fixing component 6. Then, use the healthy leg to assist the affected leg to slowly flex, hold for 5 seconds and then relax. Repeat 10 times. Later, the slider 68 can be fixed to increase the resistance.

[0043] 2. Wall sliding training, suitable for the middle stage. Set the rotating board 2 to rotate the head vertically. The patient lies supine on the support board 1, fixes both feet on the fixing component 6, and slowly slides down to the maximum knee flexion angle, holding for 10 seconds. Do 3 sets a day. In the later stage, the slider 68 can be fixed to increase the resistance.

[0044] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
