[0027] Example 1

[0028] like Figures 1 to 5As shown, the rehabilitation treatment device for sports-related knee injuries in this embodiment 1 includes a base 1, an adjustable support 2, a telescopic component 7, a first support plate 3, a second support plate 4, a third support plate 5, and an adjustment component 8. The adjustable support 2 is connected to the middle of the base 1. By designing the adjustable support 2, the height of the entire device can be adjusted according to the patient's height and the condition of the knee injury, making it more comfortable and convenient for the patient to receive rehabilitation treatment.

[0029] Specifically, the top of the adjustable support 2 is fixedly connected to a second support plate 4, and protective plates 41 are symmetrically arranged on the second support plate 4. Two third support plates 5 are symmetrically hinged to the left end of the second support plate 4. Two first hinge seats 6 are symmetrically fixedly connected to the left side of the base 1. A second hinge seat 51 is fixedly connected to the bottom of each third support plate 5. The first hinge seat 6 and the second hinge seat 51 are arranged correspondingly. The two ends of the telescopic member 7 are respectively hinged to the corresponding first hinge seat 6 and the second hinge seat 51, that is, the first hinge seat 6 and the second hinge seat 51 are arranged one-to-one, and the corresponding first hinge seat 6 and the second hinge seat 51 are connected by a telescopic member 7. Preferably, the telescopic member 7 is an electric telescopic rod, a cylinder or a hydraulic cylinder.

[0030] At this time, the telescopic component 7 allows the third support plate 5 to be angled relative to the base 1, thereby changing the relative position between the third support plate 5 and the second support plate 4, thus adapting to the different knee flexion degrees and rehabilitation needs of different patients and providing a personalized treatment experience. The protective plate 41 symmetrically arranged on the second support plate 4 can increase the stability of the device and prevent patients from falling due to improper movements during treatment. Preferably, the protective plate 41 is detachably connected to the second support plate 4.

[0031] Furthermore, two first support plates 3 are symmetrically hinged to the right end of the second support plate 4, and an adjustment component 8 is connected between the two first support plates 3. A connecting plate 33 and an arc-shaped plate 31 are sequentially fixed to the bottom of each first support plate 3. The connecting plate 33 is a straight plate, and the arc-shaped plate 31 has several adjustment holes 32. A fixing plate 9 is fixed to the right side of the base 1. Several mating holes 92 are opened vertically on both sides of the fixing plate 9. Fixing bolts pass through the adjustment holes 32 of the arc-shaped plate 31 and engage with the mating holes 92 of the fixing plate 9 to adjust the position of the first support plates 3 and the adjustment component 8. To better protect the first support plates 3, a buffer pad 91 is provided at the top of the fixing plate 9. The buffer pad 91 can be made of rubber.

[0032] In this embodiment, the position of the first support plate 3 can be adjusted by the cooperation between the adjustment hole 32 of the arc plate 31 and the mating hole 92 of the fixed plate 9. This allows for adjustment of the patient's upper body posture according to their specific condition, thereby improving the treatment effect. Simultaneously, the hinged design between the first support plate 3, the second support plate 4, and the third support plate 5 ensures the stability and support of the device during the adjustment process.

[0033] Specifically, the adjustment assembly 8 includes a drive motor 81, a threaded drive rod 82, a connecting rod 84, and a mounting plate 89. A connecting plate 87, a positioning plate 88, and a rotating shaft 86 are sequentially fixed between the two first support plates 3. The drive motor 81 is mounted in the middle of the connecting plate 87, and its output end is connected to one end of the threaded drive rod 82. The other end of the threaded drive rod 82 is rotatably connected to the positioning plate 88. A lower connecting block 83 is threadedly connected to the threaded drive rod 82. The mounting plate 89 is fixed to the side wall of the rotating shaft 86. An upper connecting block 85 is fixed to the bottom wall of the mounting plate 89 at the end away from the rotating shaft 86. One end of the connecting rod 84 is hinged to the upper connecting block 85, and the other end is hinged to the lower connecting block 83. A backing plate 891 is mounted on the mounting plate 89, and the backing plate 891 is located between the two first support plates 3. Preferably, a backing cushion is fixed to the backing plate 891.

[0034] In this embodiment, the installation of the drive motor 81 enables electric adjustment of the positions of the mounting plate 89 and the backrest 891, making the rehabilitation treatment process more automated and convenient. Patients can easily adjust the posture of their upper body by controlling the operation of the drive motor 81. The backrest cushion fixed to the backrest 891 improves the patient's comfort during rehabilitation treatment and reduces fatigue that may be caused by prolonged treatment. The material and design of the backrest cushion take into account ergonomic principles, so as to better fit the patient's body curves and provide better support.

[0035] The adjustable support 2 includes an upper adjusting seat 22 and a lower fixed seat 21. The lower fixed seat 21 is fixedly connected to the base 1. The top end of the upper adjusting seat 22 is fixedly connected to the second support plate 4 and the bottom end is inserted into the lower fixed seat 21. Several positioning holes 23 are correspondingly opened on the upper adjusting seat 22 and the lower fixed seat 21. The adjusting bolt passes through the positioning hole 23 of the lower fixed seat 21 and then cooperates with the positioning hole 23 of the upper adjusting seat 22 to realize the adjustment of the height of the upper adjusting seat 22.

[0036] At this point, the height of the upper adjusting seat 22 can be easily adjusted using the corresponding positioning holes 23 on the upper adjusting seat 22 and the lower fixing seat 21, along with the adjusting bolts. This allows for quick and accurate adjustment of the height of the second support plate 4 based on the patient's height, the degree of knee joint injury, and rehabilitation needs. Furthermore, the design of the bottom end of the upper adjusting seat 22 being inserted into the lower fixing seat 21 not only ensures the stability of the adjustment process but also provides excellent support. Even after height adjustment, the device remains stable and does not easily wobble, thus ensuring the safety and comfort of the patient during rehabilitation treatment.

[0037] In addition, several adjustable feet 11 are symmetrically installed at the bottom of the base 1. By adjusting the height of the adjustable feet 11, the height of the device can be further fine-tuned to adapt to the height and rehabilitation needs of different patients, making the device more flexible in height adjustment and able to meet the personalized needs of more patients. Furthermore, the adjustable feet 11 not only increase the contact area between the device and the ground, but also improve the stability of the entire device through their stable support structure. Even if the patient makes a large range of motion during rehabilitation training, the device can remain stable and ensure the patient's safety.

[0038] When using the rehabilitation device for sports-related knee injuries in this embodiment, if rehabilitation treatment is needed for a patient's sports-injured knee joint, the patient first sits on the second support plate 4 and leans their back against the backrest 891 of the adjustment component 8. At this time, the thigh is placed on the second support plate 4, and the lower leg that needs rehabilitation treatment is placed on the corresponding third support plate 5. At this time, the position of the first support plate 3 can be adjusted by the cooperation between the adjustment hole 32 of the arc plate 31 and the mating hole 92 of the fixed plate 9, which can initially adjust the patient's upper body posture according to the patient's specific situation. Then, by retracting the telescopic component 7, the third support plate 5 and the second support plate 4 are bent at a specified angle. At this time, the patient's thigh and the lower leg that needs rehabilitation treatment are bent at the specified angle. As the telescopic component 7 is continuously extended and retracted, the patient's leg is continuously bent, thus facilitating the rehabilitation treatment of the knee joint.

[0039] When a patient needs to adjust their upper body posture during rehabilitation therapy, the drive motor 81 drives the threaded drive rod 82 to rotate, which in turn moves the lower connecting block 83 along the length of the threaded drive rod 82. As the lower connecting block 83 moves closer to the drive motor 81, the angle of the mounting plate 89 can be adjusted by the movement of the connecting rod 84, thereby adjusting the angle of the backrest 891. The patient can adjust their upper body posture at any time during rehabilitation therapy, which is convenient and improves the patient's comfort during rehabilitation therapy.

[0040] Example 2

[0041] like Figure 6As shown, the difference between this embodiment 2 and embodiment 1 is that it also includes a heat therapy component 10. The heat therapy component 10 is disposed between the second support plate 4 and the third support plate 5. The heat therapy component 10 includes a connector 101, a flexible heating band 102, and a heat therapy band 103. One end of the connector 101 is symmetrically fixed to both ends of the flexible heating band 102, and the other end of the connector 101 is fixed to the second support plate 4 or the third support plate 5. The heat therapy band 103 is installed at the bottom of the flexible heating band 102. At this time, by setting the heat therapy component 10, the flexible heating band 102 can fit the knee joint well. During the rehabilitation treatment, the patient can apply heat to the knee joint, thereby improving the efficiency of knee joint rehabilitation.

[0042] Preferably, the connector 101 is an elastic band. One end of the elastic band is fixedly connected to the side of the second support plate 4 or the third support plate 5, and the other end is fixedly connected to the side of the flexible heating band 102. The elastic band can automatically adjust its tightness according to the actual use to ensure patient comfort.

[0043] This utility model relates to a rehabilitation treatment device for knee joint injuries caused by sports. It can adjust the patient's upper body posture at any time to avoid fatigue and facilitate treatment. It is also highly adjustable, allowing adjustment not only of the angle of the first support plate and the backrest plate, but also of the height of the second support plate.
