For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] As shown in the accompanying drawings, the utility model includes a base 1, a pedal 2 and a counter 3. The pedal 2 is rotatably mounted on the base 1, and an elastic tension member 5 is provided between the pedal 2 and the base 1. The counter 3 is mounted on the base 1 located at the rear side of the pedal 2 and cooperates with the pedal 2 to count.

[0024] The base 1 and the pedal 2 are both rectangular wooden boards, both of which are 12-18 mm thick and 150-200 mm wide. The pedal 2 is 300 mm long, and one end of its bottom is in contact with the base 1 .

[0025] By default, the pedal 2 and the base 1 are vertical. When in use, the heel is placed on the base 1, the sole of the foot is on the pedal 2, and then the ankle joint plantar flexion and dorsiflexion exercises are performed. The elastic tension member 5 is convenient for the pedal 2 to reset during dorsiflexion, and at the same time provides a certain resistance for plantar flexion. When performing plantar flexion, the pedal 2 tilts and touches the counter 3 once. The counter 3 can record the number of plantar flexion exercises, which is convenient for medical staff to check whether the patient has completed the full amount of exercise. In this case, the counter 3 is an electronic counter, which is provided with a contact switch. Every time the pedal 2 touches the contact switch, the counter 3 can count once.

[0026] Optionally, the pedal 2 is hinged to the base 1 through a hinge. When installed, the hinge is located on the pedal 2 on the opposite side of the elastic tension member 5. By default, the elastic tension member 5 can make the pedal 2 and the base 1 vertical, and the pedal 2 can only tilt to the side of the counter 3 when subjected to external force.

[0027] The first implementation mode of the elastic tension member 5 is that the elastic tension member 5 is two tension springs, and the two tension springs are respectively connected to the two sides of the pedal 2 and the base 1, so that the pedal 2 can remain stable when tilting, and the tension springs are used to control the pedal 2 to reset and provide a certain resistance for plantar flexion.

[0028] Furthermore, the two tension springs at one end of the pedal 2 are connected by a limit rod 6, and a group of tension adjustment slots 7 matched with the limit rod 6 are provided on the rear side of the pedal 2. It is used to adjust the tension of the tension spring according to the actual situation of the patient. When adjusting, it is only necessary to move the limit rod 6 to the corresponding tension adjustment slot 7. During production, the limit rod 6 uses a metal rod, and limit blocks are provided at both ends to prevent the tension spring from falling off. The opening of the tension adjustment slot 7 is tilted upward. When the pedal 2 is tilted, it can prevent the limit rod 6 from falling off from the tension adjustment slot 7. A handle can also be provided in the middle of the limit rod 6. When adjusting, it is only necessary to pull the handle upward to pull out the limit rod 6 and quickly place it in the corresponding tension adjustment slot 7.

[0029] The second embodiment of the elastic tension member 5 is that the elastic tension member 5 is two adjustable rope-driven tensioners, which are respectively connected to both sides of the pedal 2 and the base 1, so that the pedal 2 can remain stable when tilting, and the pedal 2 is controlled to be reset by the adjustable rope-driven tensioner, and a certain resistance is provided for plantar flexion. The adjustable rope-driven tensioner can be a Huamin rope-driven training tensioner sold on the market, which has three gears of tension adjustment, and can adjust the tension of the rope. One end of the seat of the tensioner is hinged on the base 1, and one end of the rope is hinged on the pedal 2. When the pedal 2 rotates backward, the rope is pulled out, and when the pedal 2 is reset, the rope is automatically retracted into the seat of the tensioner.

[0030] Furthermore, an angle adjustment device is provided on the base 1 located on the rear side of the pedal 2, and the angle adjustment device includes a fixed support seat 8 and a movable support seat 9. A locking screw 10 is provided at one end of the movable support seat 9, and the counter 3 is installed on the movable support seat 9. An inclined support portion bent toward the pedal 2 is provided at one end of the fixed support seat 8, and a long hole for avoiding the locking screw is opened on the inclined support portion. The movable support seat 9 can be adjustably installed on the fixed support seat 8 through the locking screw 10.

[0031] The distance between the counter 3 and the pedal 2 is adjusted by adjusting the position of the movable support seat 9 on the fixed support seat 8, so as to control the angle of the tilting of the pedal 2. The closer the counter 3 is to the pedal 2, the smaller the maximum tilting angle of the pedal 2. It can be adjusted according to the specific situation of the patient.

[0032] The counter 3 is perpendicular to the inclined support portion, and after the pedal 2 is tilted, the rear side thereof can contact with the contact switch of the counter 3, thereby facilitating counting.

[0033] A set of scale marks are provided on the fixed support seat 8, which are respectively at 30°, 45°, and 60°, so as to facilitate the rapid and accurate adjustment of the maximum tilting angle of the pedal 2.

[0034] Furthermore, it also has a length adjustment slider 15. The bottom of the base 1 is provided with a length adjustment slider installation groove. The length adjustment slider 15 is slidably connected in the groove and locked by a screw. One end of the length adjustment slider 15 is provided with a limit baffle 16.

[0035] When the patient lies flat on the bed to exercise the ankle, the trainer is placed at the end of the bed. Due to its light weight, the trainer is easy to slide backwards during exercise. If the base 1 is fixed to the baffle at the end of the bed, the patient's lying position needs to be adjusted due to the different heights of the patients, which is not convenient to use. Therefore, in this case, a length adjustment slider 15 is provided on the base 1, and the patient's lying position remains unchanged. According to the position of the patient's feet, the position of the base 1 and the pedal 2 is fixed by adjusting the position of the length adjustment slider 15, and the limit baffle 16 is pressed against the baffle at the end of the bed.

[0036] Furthermore, a retractable support rod is provided between the limit baffle 16 and the base 1, and the retractable support rod includes a fixed sleeve rod 17 and a movable rod 18, one end of the movable rod 18 is inserted into the fixed sleeve rod 17 and locked by a locking sleeve 19. The limit baffle 16 and the base 1 are respectively provided with hinge supports, and the fixed sleeve rod 17 and the movable rod 18 are respectively hinged to the corresponding hinge supports, and a triangular fixed support is formed between the retractable support rod, the limit baffle 16 and the length adjustment slider 15, which is more stable when all need to move.
