[0028] The ankle trainer provided by the embodiment of the application can include a base frame 1, a rotating shaft 2, a rotating cylinder 3 and a pedal 4. The base frame 1 has side plate blocks 11 and a center plate block 12 arranged opposite in a first direction. The side plate blocks 11 have a cavity. The first direction is the same as the width direction of the side plate blocks 11. The rotating shaft 2 is rotatably connected between the side plate blocks 11 and the center plate block 12 and inserted into the cavity. The rotating shaft 2 has the freedom of rotating around its own axis and the axis direction is the same as the first direction. The rotating cylinder 3 is arranged in the cavity and connected with the rotating shaft 2. The rotating cylinder 3 provides driving force for the rotating shaft 2 to rotate reciprocatingly. The pedal 4 is fixed on the rotating shaft 2 and located between the side plate blocks 11 and the center plate block 12. The length direction of the pedal 4 is perpendicular to the first direction.

[0029] It should be noted that the ankle trainer has a length, a width and a height, the width direction of the side plate 11 is the same as the width direction of the ankle trainer, that is, the first direction X, the height direction of the side plate 11 is the same as the height direction of the ankle trainer, that is, the second direction Y, and the length direction of the side plate 11 is the same as the width length direction of the ankle trainer, that is, the third direction Z; during use of the ankle trainer, the second direction can be the same as the direction of gravity.

[0030] The rotating cylinder 3 can be a gear type rotating angle cylinder, and has an adjusting screw thereon, which can be adjusted to change the swing angle of the output end of the gear type rotating angle cylinder; the specific swing angle can be between 20° and 60°, and can be 20°, 30°, 40°, 50° and 60°, etc.

[0031] In addition, the rotating speed of the output end of the rotating cylinder 3 can be changed by changing the gas pressure input into the rotating cylinder 3, so as to conveniently and quickly adjust the speed and angle of the swing of the pedal 4.

[0033] Further, two strap sets can be provided on one pedal 4 to fix the positions of the instep and the heel of the user, and the two strap sets are arranged in the length direction of the pedal 4, so that the fixing effect is better.

[0034] Reference Figure 1 With Figure 4 In the example embodiment, the side plate 11, the rotating shaft 2, the rotating cylinder 3 and the pedal 4 constitute a rotating assembly; wherein, there are two groups of rotating assemblies, and the two groups of rotating assemblies are oppositely arranged on the two sides of the center plate 12 in the first direction.

[0035] Specifically, two groups of rotating assemblies are provided, and the pedal 4 has two pedals, so that the user can put his feet on the two pedals respectively to perform ankle training, and the training efficiency is higher.

[0036] Further, the two rotating cylinders 3 can drive the two rotating shafts 2 to swing independently, thereby driving the two pedals 4 to swing independently, so that various training modes can be evolved. For example, only one of the two pedals 4 can rotate, and the other pedal 4 does not swing, thereby performing single-leg training; the two pedals 4 can swing in the same direction; the two pedals 4 can swing in opposite directions; the two pedals 4 can swing at different speeds, so that the two pedals 4 sometimes swing in the same direction and sometimes swing in opposite directions; the training difficulty of the above training modes gradually increases, and the actual needs can be selected.

[0037] Reference Figure 2 In the example embodiment, the ankle trainer can further include a support rod 51, a cross beam 52, and two handlebars 53. The support rod 51 is arranged on the base frame 1 and extends in a second direction, which is the same as the height direction of the side plate block 11. The cross beam 52 is fixed to one end of the support rod 51 away from the base frame 1 and extends in a first direction. The two handlebars 53 are arranged on the side of the cross beam 52 away from the support rod 51, and the two handlebars 53 are arranged opposite to each other in the first direction.

[0038] As shown in Figure 2 When the user stands on the pedals 4 with both feet, the user can hold the handlebars 53 on the cross beam 52 with both hands, which can effectively prevent the user from falling during the swinging of the pedals 4 and improve the overall safety performance of the equipment.

[0039] Further, the support rod 51 is a telescopic rod and has a degree of freedom of telescoping in the second direction, so that the height of the handlebar 53 can be adjusted by adjusting the telescoping length of the support rod 51 to adapt to the gripping of users of different heights, and the use is more convenient.

[0040] It should be understood that the telescopic rod can be a cylindrical telescopic rod with self-locking, and the specific structure has many conventional schemes, which will not be described in detail here. Figures 1-4 The support rod 51 in

[0041] As shown in Figure 2 The support rod 51 has two and is arranged opposite to each other in the first direction, so that the handlebar 53 is more stable, and the overall safety of the ankle trainer is further improved. Especially when the support rod 51 is a telescopic rod, the single telescopic rod has low strength, and the two support rods 51 can effectively replace the stability of the handlebar 53.

The sliding rail 71 is fixed to one side of the support plate 61 in the first direction and extends in the same direction as the support plate 61. The sliding block 72 is in sliding cooperation with the sliding rail 71. The sliding plate 73 is fixed to the sliding block 72 and located on the side of the support plate 61 away from the extending part. The seat 62 is fixed to the sliding plate 73. The locking part is arranged on the sliding plate 73 and cooperates with the support plate 61 to lock or release the sliding degree of freedom of the sliding plate 73.

[0049] Specifically, the sliding plate 73 can slide along the extending direction of the sliding rail 71 through the sliding block 72. The sliding plate 73 is fixed to the seat 62. The extending direction of the sliding rail 71 is the same as the extending direction of the support plate 61. Therefore, the seat 62 can slide along the extending direction of the support plate 61.

[0050] Reference Figure 2 and Figure 3 In the example embodiment, the sliding rail 71 and the sliding block 72 form a sliding pair. There are two sliding pairs arranged on the two sides of the support plate 61 in the first direction. The sliding plate 73 is fixed to the two sliding blocks 72.

[0051] Specifically, the sliding plate 73 is located on the side of the support plate 61 away from the extending part. The two sliding blocks 72 are located on the two sides of the support plate 61 in the first direction. In this way, the two sides of the sliding plate 73 in the first direction are supported by the two sliding blocks 72, which ensures the stable sliding of the sliding plate 73 and the seat 62.

[0052] Reference Figure 2 In the example embodiment, there is a gap between the sliding plate 73 and the support plate 61. The locking part can include a screw rod 8, a friction pad, and an adjusting knob. The screw rod 8 penetrates the sliding plate 73 and is threadedly connected to the sliding plate 73. The friction pad is fixed to one end of the screw rod 8 close to the support plate 61. The adjusting knob is fixed to the other end of the screw rod 8 away from the support plate 61.

[0053] Specifically, when the position of the seat 62 is fixed, the adjusting knob is rotated to tighten the screw rod 8. The friction pad is in contact with the support plate 61. The position of the sliding plate 73 is fixed and cannot be further slid. Therefore, the position of the seat 62 is fixed. When the position of the seat 62 is adjusted, the adjusting knob is rotated to loosen the screw rod 8. The friction pad is separated from the support plate 61. The sliding plate 73 can slide along the extending direction of the support plate 61. Therefore, the position of the seat 62 is adjusted.
