DETAILED DESCRIPTION

[0019] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] Please refer to Figure 1-5 A bone injury rehabilitation aid comprises a base 1, wherein an L-shaped movable plate 2 is arranged in the base 1, wherein the L-shaped movable plate 2 comprises a U-shaped connecting plate 21 and a pedal 22, wherein the U-shaped connecting plate 21 is fixedly connected to the pedal 22 and is L-shaped as a whole, wherein the U-shaped connecting plate 21 is movably connected to the base 1 through a hinge shaft 11, wherein one end of the hinge shaft 11 is fixedly connected to the U-shaped connecting plate 21, and the other end is rotatably connected to the base 1, so as to ensure that the L-shaped movable plate 2 can swing in the base 1 through the hinge shaft 11; during use, the patient's ankle is placed on the denim-like U-shaped connecting plate 21, and then the sole of the foot is placed on the pedal 22. At this time, when the L-shaped movable plate 2 swings in the base 1 through the hinge shaft 11, the patient's ankle bone joint can be moved, and the ankle forward and backward swinging nerves can be stimulated, thereby improving the rehabilitation effect.

[0021] After ankle fractures, sprains and other injuries, patients need to stay in bed for a long time. After a period of overall drug rehabilitation, the ankle becomes inconvenient to move, especially for middle-aged and elderly people, whose recovery ability is relatively low and they cannot actively move the ankle joint in the early stage of activity training. Therefore, with the help of the rehabilitation aid of this application, it is convenient to encourage patients to move and find neural memory.

[0022] In this embodiment, the L-shaped movable plate 2 is swung by a driving mechanism, and the driving mechanism includes a driven gear 12, a driving gear 13, a chain 14 and a transmission shaft 15. The driven gear 12 is fixed to the outer wall of the hinge shaft 11, and the driving gear 13 is arranged directly below the driven gear 12 and is rotatably connected to the inner wall of the base 1. The driving gear 13 and the driven gear 12 are transmitted by the chain 14, and the transmission shaft 15 extends outward through the driving gear 13, wherein a motor cover 3 is provided on one side of the base 1, and a stepping motor is provided in the motor cover 3, and the output end of the stepping motor is coaxially fixedly connected with the transmission shaft 15.

[0023] At this time, when the stepper motor is driven to run, the transmission shaft 15 starts to rotate, and the chain 14, the driving gear 13 and the driven gear 12 start to rotate in the base 1. Since the driven gear 12 is fixed on the hinge shaft 11, and one end of the hinge shaft 11 is fixedly connected to the U-shaped connecting plate 21, and the other end is rotatably connected to the base 1, when the driven gear 12 rotates, the U-shaped connecting plate 21 is driven to swing in the base 1 through the hinge shaft 11. In addition, the U-shaped connecting plate 21 is fixed to the pedal 22, so that the L-shaped movable plate 2 can swing in the base 1. The swing of the L-shaped movable plate 2 can prompt the patient to move his ankle to facilitate rehabilitation.

[0024] In this embodiment, after the patient's foot is placed on the pedal 22, the calf is suspended in the air without external support, which is quite strenuous. Therefore, an inclined plate 4 is also provided in the base 1. The inclined plate 4 is inclined toward the U-shaped connecting plate 21, and the surface of the inclined plate 4 is provided with a downward arc-shaped depression. When in use, the patient's calf is placed in the arc-shaped depression of the inclined plate 4, the ankle is placed in the U-shaped connecting plate 21, and the sole of the foot is placed on the pedal 22. Such placement can not only exercise the rehabilitation ankle, but also put the patient in a relaxed state and improve the comfort level.

[0025] As a preferred embodiment, a first elastic band 211 is provided in the U-shaped connecting plate 21, a second elastic band 221 is provided on the surface of the pedal 22, and a third elastic band 41 is provided on the surface of the inclined plate 4 on both sides of the arc-shaped depression. When in use, the first elastic band 211 binds the ankle to the U-shaped connecting plate 21, the second elastic band 221 binds the leg to the pedal 22, and the third elastic band 41 binds the calf to the inclined plate 4. At this time, the limbs of the patient are not easy to be separated during exercise; the reciprocating rotation of the stepping motor encourages the patient to exercise and accelerates recovery.

[0026] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
