[0033] The present embodiment is combined with the accompanying drawings Figures 1 to 9 A kind of ankle rehabilitation training device is described in detail.

[0034] The present embodiment is combined with the accompanying drawings

[0035] The upper part of the calf guard 2 is provided with two calf bands 8, and the side of the calf guard 2 is provided with a rudder 9. The front end of the rotating shaft 1 of the rudder 9 is provided with a bevel gear 10, and the bevel gear 10 is engaged with a bevel gear plate 11. The bevel gear 10 is smaller than the bevel gear plate 11, and the bevel gear plate 11 is fixedly connected with the foot supporting plate 1. The calf guard 2 rotates inside the bevel gear plate 11. The foot band 3 and the calf band 8 are both magic tape bands that can be self-adhesive at both ends and are worn in the holes of the foot supporting plate 1 and the calf guard 2.

[0036] The rear end of the foot supporting plate 1 is provided with two rollers 12, and the two rollers 12 share a rotating shaft 2. The rotating shaft 2 rotates in a sleeve 13, and the sleeve 13 is fixedly connected with the rear end of the foot supporting plate 1. The bottom of the foot supporting plate 1 is provided with two ball bearings 14, which can roll freely. The ball bearings 14 are flush with the bottom of the rollers 12.

[0037] The rotating shaft 2 is provided with a gear structure 15 in the middle, and the sleeve 13 is provided with a knob bolt 16 in the middle. The knob bolt 16 is located at the top of the gear structure 15, and the bottom of the knob bolt 16 is a sharp tip. The sharp tip can limit the gear structure 15. The sharp tip can be inserted between the teeth of the gear structure 15 to prevent rotation.

[0038] The foot supporting plate 1 comprises two side fences 17, the bevel gear disc 11 is fixedly connected with the fences 17, the foot binding belt 3 is arranged on the fence 17, and the calf guard 2 is rotatably connected with the fence 17 on the inner side of the bevel gear disc 11.

[0039] The partition plate 5 is fixedly connected with the foot supporting plate 1, and the height of the partition plate 5 is half of the natural full inflation state of the air cushion 4 when the air cushion 4 is naturally inflated.

[0040] The calf guard 2 is provided with two fixed support blocks 18 on one side, and the rotating shaft 1 20 penetrates through the support blocks 18 to rotate.

[0041] The calf guard 2 is provided with a fixed shell 19 on one side, the shell 19 covers the rudder 9, the rotating shaft 1 20 and the bevel gear disc 11, and the shell 19 plays a protective role.

[0042] The rudder 9 is connected with a handheld controller. The controller is the same as the controller in the background art, and is used for handheld operation to start the rudder 9 to enter the working mode.

[0043] In the specific implementation, the structure in the drawing is used for the right foot, and if used for the left foot, the shell 19, the rudder 9, the rotating shaft 1 20 and the bevel gear disc 11 are arranged on the left side of the calf guard 2.

[0044] During training, the right foot is placed on the air cushion 4, the calf is placed in the calf guard 2, and then the foot binding belt 3 and the calf binding belt 8 are bound, one hand holds the controller, and the other hand holds the inflatable ball 7. The two air cushions 4 are naturally inflated, the foot is flatly and softly supported, and comfortable buffering is provided. The controller is operated to start the rudder 9, the rotating shaft 1 20 and the bevel gear 10 are rotated, the bevel gear disc 1 1 is driven to rotate, the foot supporting plate 1 and the calf guard 2 are rotated, and the ankle joint can be reciprocally rotated for regular flexion and extension training.

[0045] If lateral activity training of the ankle joint is required, for example, the foot is inwardly moved, the right inflatable ball 7 can be appropriately deflated, the left inflatable ball 7 is pinched by hand, and repeated inflation and deflation are performed, so that the foot is reciprocally rotated to achieve the training effect. The foot is outwardly moved for training, and the lateral activity training can be combined with the forward and backward activity training.

[0046] When the roller 12 can freely move, the foot supporting plate 1 can move forward and backward on the ground, at this time, the calf can be flexed and extended, the foot can be placed on the ground or can be raised when the calf is stretched forward, and the ankle joint activity training can be performed to promote the training effect. The knob screw 16 is rotated to make the sharp head inserted into the gear structure 15 to fix the roller 12, so that the foot supporting plate 1 cannot freely move on the ground, and the calf cannot freely flex and extend. At this time, appropriate fixed leg postures can be selected for ankle joint activity training.

[0047] The above describes the present application and its embodiments, which is not limited, and the actual protection scope is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
