Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation technology, specifically to a strength training device for foot and ankle repair. Background Technology

[0002] The ankle, or foot-ankle joint, is the part of the human foot that connects to the leg. It consists of seven tarsal bones, plus the metatarsal bones of the foot and the bones of the lower leg. The foot is considered the second heart of the body, and the ankle is a crucial gateway for blood flow in both feet. The smoothness of blood circulation in the lower body greatly affects the overall flow of qi and blood throughout the body. Since the ankle is a vital area for blood flow in both feet, maintaining its flexibility and suppleness through exercises or massage is highly beneficial to health.

[0003] In the course of life, the feet and ankles are inevitably injured. After an injury occurs, treatment is required. During the treatment process, the feet, ankles, and related muscles will atrophy due to long-term rest. Therefore, after the treatment is completed, strength training to repair the feet and ankles is necessary.

[0004] Strength training for foot and ankle rehabilitation often involves rising onto the toes to create an unstable position for the ankle joint, thereby strengthening the calf and ankle muscles. This process also involves changing the position of the toes to further enhance the ankle joint's strength.

[0005] However, there are still some deficiencies and shortcomings in the current foot and ankle rehabilitation strength training process. The specific areas that need improvement are as follows: 1. Currently, during the process of strengthening and repairing the ankles, it is not easy for the trainees to rotate their toes to change their position and achieve the purpose of strengthening the ankles. Therefore, it brings certain inconvenience to the trainees' ankle repair and repair training. 2. Currently, during the process of strengthening and repairing the ankles, the trainees cannot control the amount of contact between their toes and the ground according to their own needs, which makes it difficult for them to carry out progressive and safe training according to their own situation. 3. Currently, during the process of reparative strength training for the foot and ankle, the trainee cannot be promptly restricted or stopped when training errors occur, which fails to reduce the probability of secondary foot and ankle injuries caused by the trainee's own falls, thus reducing the safety of the trainee during the reparative strength training process. 4. Currently, in the process of strengthening and repairing the ankles, it is not possible to help the trainee maintain the distance between their toes and shoulders, thus failing to maintain the trainee's body stability and achieve good training results, thereby reducing the quality of the trainee's ankle strength repair training.

[0006] 5. Currently, during the process of foot and ankle repair strength training, there is no way to provide certain assistance when the exerciser's foot and ankle strength is insufficient, thereby reducing the exerciser's motivation and confidence in foot and ankle repair strength training. Summary of the Invention

The two ends of two rotating torsion springs are respectively fixedly connected to the opposite surfaces of the two rotating disks and the two auxiliary sliders. The two rotating torsion springs are respectively sleeved on the two rotating shafts.

[0015] (III) Beneficial Effects The beneficial effects of this invention are as follows: 1. This foot and ankle strength training device features a top plate that allows the user to step on and easily rotate the toes. During rotation, the top plate is assisted by a groove on the upper part of the central support, enabling it to easily rotate under force. This helps the user change the position of the toes, thus providing multi-angle strength recovery training for the foot and ankle, maintaining a high quality of foot and ankle strength recovery training. During the rotation of the top plate, it is supported by a connecting groove, a connecting plate, a synchronization block, an auxiliary rotating plate, an auxiliary ring, and an auxiliary groove, allowing the user's toes to easily rotate against the contact surface of the connecting plate and the top plate. This increases the rotational force the ankle can withstand during training, thus maintaining a more comprehensive foot and ankle strength recovery training. This solves the problem that in current ankle and foot repair strength training, it is not easy for trainees to rotate their toes to change their toe position and thus achieve the purpose of exercising the ankle and foot, which brings certain inconvenience to the trainees' ankle and foot repair training.

[0016] 2. This foot and ankle repair strength training device controls the rotation of two adjusting screws via two first turntables. The rotation of these screws, in conjunction with two adjusting cylinders, causes two limiting slide plates to move. Subsequently, the two limiting slide plates slide along limiting grooves. During this sliding process, two hinge seats (1) drive the telescopic connecting plate to unfold or retract. The telescopic connecting plate, during its unfolding or retraction, utilizes hinge seats (2) fixedly connected to the top plate for auxiliary positioning. Simultaneously, the telescopic connecting plate moves along with a cooperating connecting plate, which, during its movement, slides and unfolds or retracts in conjunction with a cooperating groove. The user can then adjust the foot surface according to their own foot and ankle condition, allowing the user to support themselves with their toes. During the up-and-down movement of the body to exercise the ankles, the supporting part of the toes is altered. The force on the toes positively influences the force on the ankles. When the toes bear greater force, the ankle bears less, allowing for initial training; when the toes bear less force, the ankle bears more, allowing for subsequent high-intensity training. This gradual adjustment facilitates progressive ankle strength training, solving the problem that current ankle strength training methods often fail to allow trainees to control the amount of contact between their toes and the ground according to their individual needs, hindering safe and progressive training.

[0017] 3. This foot and ankle repair strength training device uses two second hinge pins to drive the lower ends of two protective ropes to slide within a sliding groove. As the two stabilizing plates approach each other, the upper ends of the two protective ropes are driven to move via two first connecting pins. During this process, the central hinge pin connected at the center of the two protective ropes ensures their relative position, thus providing protection and blocking during the exercise. This reduces the risk of falls caused by forward tilting due to slippage of the toes, further improving the safety of the exerciser. This solves the problem that current foot and ankle repair strength training devices often fail to promptly restrict and stop exercise errors, thus failing to reduce the probability of secondary foot and ankle injuries caused by falls. Therefore, this device reduces the safety issue during the repair strength training process.

[0018] 4. This foot and ankle repair strength training device connects to the worker's armpit via elastic blocks. When the two elastic blocks are clamped, they drive two arc-shaped blocks to move. During this movement, the two arc-shaped blocks, via two stabilizing plates, drive two movable columns. The movement of the movable columns, in turn, drives two storage cylinders via two limiting discs. The coordination between the movable columns and storage cylinders accommodates users of different heights. The limiting discs on the movable columns maintain the connection between the columns and storage cylinders, and their relative sealing provides damping, thus maintaining support for the user and improving safety to a certain extent. The movement of the two storage cylinders also drives two follower sliders to move synchronously. During synchronous movement, the movement is limited by the follow-up sliding grooves on the base plate. Because the armpit and shoulder are close together, the two follow-up sliders can be moved to a position approximating the exerciser's shoulder width. This allows the distance between the two central pillars to be adjusted to approximately the width of the exerciser's shoulders. Different exercisers can quickly adjust the distance between the two central pillars to match their shoulder width, thus maintaining the quality of subsequent ankle strength rehabilitation training. This solves the problem that current ankle strength rehabilitation training often fails to help exercisers maintain a shoulder-width distance between their toes, hindering body stability and training effectiveness, and ultimately reducing the quality of ankle strength rehabilitation training. This foot and ankle repair strength training device connects to the user's foot and ankle via a pedal. A support column then drives a power connecting plate downwards. During this downward movement, the power connecting plate, via a power hinge, rotates a rotary disc. The rotary disc is supported by a rotary shaft, which in turn rotates the power connecting plate and the rotary disc. During the rotation of the rotary disc, it overcomes the torque generated by the auxiliary slider and the torsion spring. Simultaneously, the support connecting plate and the support hinge work together to limit the support column, maintaining the pedal's relatively vertical arc-shaped movement. Furthermore, it utilizes an adapter sleeve and an adapter elongated hole... After the pedal is pressed downwards, the torsion spring provides a rotational force, causing the rotary disc to return to its original position and rotate. This rotation drives the power connecting plate upwards, which in turn drives the bearing column, causing the pedal to push the exerciser's ankle upwards. This provides some assistance to the exerciser, allowing for ankle strength recovery training in conjunction with the upward movement of the ankle. This addresses the current shortcomings in ankle strength recovery training, which often fail to provide adequate assistance when the exerciser's ankle strength is insufficient. This helps improve the exerciser's motivation and confidence in ankle strength recovery training. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-15As shown, the present invention provides a technical solution: a strength training device for foot and ankle repair, including a follow-up control device 1. The upper end of the follow-up control device 1 is equipped with a gripping device 5, which is used by the exerciser to grip and improve the stability of the upper body during foot and ankle strength recovery training. The lower end of the follow-up control device 1 is fixedly connected to a safety device 6. The safety device 6 is designed to form a forward-leaning protective net, thereby providing some resistance when the exerciser falls forward, in conjunction with the exerciser's weight limit, thus reducing the severity of injury caused by a forward-leaning fall. The safety device 6 is equipped with a stepping device 2, which allows the exerciser to step on it and also facilitates the exerciser's rotation of their toes, thereby achieving high-quality foot and ankle training. The stepping device 2 is equipped with a telescopic device 3 and a pushing device 4. The safety device 6 includes a base plate 68, which is designed to connect to the ground for stable use by the exerciser and also assists the safety device 6 in cushioning forward-leaning falls, thereby reducing the probability of serious injury caused by forward leaning. The base plate can also be used to... The base plate 68 is fixed to the ground to prevent the exerciser from leaning forward and falling, thus reducing the probability of a fall. A follower groove 67 is provided within the base plate 68, and two follower sliders 66 are slidably connected within the follower groove 67. Each follower slider 66 has a stepping device 2 and a control device 1 on its upper side. The control device 1 includes an arc-shaped plate 12, which is designed to connect with the exerciser's armpits, thereby causing the two follower sliders 66 to slide within the follower groove 67, thus reducing the distance between the two follower sliders 66. Adjusted to a state approximately equal to the width of the exerciser's shoulders, the lower end of the arc-shaped plate 12 is fixedly connected to a stabilizing plate 13, the lower end of the stabilizing plate 13 is fixedly connected to a movable column 14, the lower end of the movable column 14 is movably connected inside the storage tube 16, and the storage tube 16 is fixedly connected to the upper side of the follower slider 66. The movable column 14 and the storage tube 16 can be linked to the arc-shaped plate 12 and the follower slider 66, thereby achieving the purpose of adjusting the distance between the two follower sliders 66 to approximately equal to the width of the exerciser's shoulders, and can also be folded for easy storage when not in use.

[0022] Both follower sliders 66 have follower seats 65 fixedly connected to their upper front ends. Both follower seats 65 are hinged to one end of the protective rope 62 via second connecting pins 64. The follower seats 65 and the second connecting pins restrict the lower end of the protective rope 62 from moving synchronously with the follower sliders 66, thereby limiting one end of the protective rope 62. Furthermore, the other ends of the two protective ropes 62 are crossed and hinged to first connecting pins 61, thereby limiting the other end of the protective rope 62. Once the two protective ropes 62 are limited, they can act as a barrier to prevent or cushion the forward fall of the exerciser. The two first connecting pins 61 are fixedly connected to the front sides of the two stabilizing plates 13 respectively. A central connecting pin 63 is hinged at the intersection of the two protective ropes 62, thereby making the two protective ropes 62 in a cross shape to increase the probability of preventing the exerciser from falling forward.

[0023] A limiting disc 15 is fixedly connected to the lower end of the movable column 14. The limiting disc 15 is relatively sealed to the inner wall of the storage tube 16. The lower end of the storage tube 16 has a through hole that connects to the inside of the storage tube 16. The limiting disc 15 on the movable column 14 maintains the connection between the movable column 14 and the storage tube 16. The relative sealing between the limiting disc 15 and the storage tube 16 can also provide a certain amount of damping, thereby maintaining the support function for the exerciser during use, which can improve the safety of the exerciser to a certain extent. An elastic block 11 is fixedly connected to the upper side of the arc plate 12. The elastic block 11 has a structure that is narrow at the top and wide at the bottom. The elastic block 11 is made of wear-resistant flexible rubber, thereby improving the comfort of the exerciser when the elastic block 11 is connected to the exerciser's armpit.

[0024] The gripping device 5 includes a through slot 51 and two vertical holes 56 formed in the stabilizing plate 13. Vertical posts 52 are slidably connected to each of the two vertical holes 56. A limiting disc 57 is fixedly connected to the upper end of each vertical post 52, and an adapter block 54 is fixedly connected to the lower end of each vertical post 52. An adapting spring 53 is provided between the adapter block 54 and the stabilizing plate 13, sleeved on the vertical post 52. Both ends of the adapting spring 53 are fixedly connected to the adapter block 54 and the opposite surfaces of the stabilizing plate 13, thus accommodating exercisers with different arm lengths within a certain range. It also provides a certain upward force to assist the exerciser in stabilizing their position, thereby improving the safety of the exerciser to a certain extent. The two ends of the gripping post 55 are respectively fixedly connected to the opposite surfaces of the two adapter blocks 54. The pedaling device 2 includes a central support column 28 fixed on the follower slider 66. A top annular groove 23 is provided at the upper end of the central support column 28. A top plate 21 is rotatably connected in the top annular groove 23, which facilitates the exerciser to rotate their toes to perform comprehensive foot and ankle exercises. An auxiliary rotating plate 26 is fixedly connected to the top plate 21 through a synchronization block 213. An auxiliary ring 24 is fixedly connected to the center of the auxiliary rotating plate 26. The auxiliary ring 24 is rotatably connected in the auxiliary annular groove 25 provided on the central support column 28, so that the auxiliary rotating plate 26 can rotate in coordination with the rotation of the exerciser's feet, thereby driving the telescopic device 3 and the pushing device 4 to rotate synchronously to adapt to the exerciser's use.

[0025] The telescopic device 3 includes a limiting slide plate 31, which is slidably connected to a limiting groove 27 opened on the auxiliary rotating plate 26. An adjusting screw 32 is fixedly connected to the limiting slide plate 31, and an adjusting screw 33 is threadedly connected to the adjusting screw 32. One end of the adjusting screw 33 is rotatably connected to the inner wall of the limiting groove 27, and the other end of the adjusting screw 33 extends through a support hole 212 and is fixedly connected to a first turntable 38. The support hole 212 is opened on the side wall of the auxiliary rotating plate 26 opposite to the central support column 28. Two hinge seats 36 are fixed to the side of the limiting slide plate 31 facing the top plate 21. The top plate 21 faces the limiting slide plate 31... Two hinge seats 37 are fixed on one side. Two hinge seats 36 and two hinge seats 37 are connected by a telescopic connecting plate 34. The telescopic connecting plate 34 can rotate and extend with the adjusting screw 33, thereby driving the mating connecting plate 35 to move. During the movement of the mating connecting plate 35, it will slide and expand or contract with the mating through groove 22. Then, the exerciser can adjust the step surface according to his own foot and ankle condition. In this way, when the exerciser moves up and down with the toes as the support point to exercise the foot and ankle, the part of the toes that is supported can be changed. That is, the force on the toes will negatively affect the force on the exerciser's foot and ankle.

[0026] A connecting plate 35 is fixed to the side of the skateboard 31 facing the top plate 21. The connecting plate 35 is H-shaped to maintain the structural stability of the connecting plate 35. The side of the connecting plate 35 facing the top plate 21 passes through the connecting groove 22. The upper side of the connecting plate 35 is rough to improve the body stability of the exerciser. The connecting groove 22 is opened on the top plate 21. The upper side wall thickness of the connecting groove 22 is 1-2cm to reduce the discomfort of the exerciser when stepping on it.

[0027] The pushing device 4 includes two supporting plates 41. Each of the two supporting plates 41 has a supporting pivot 29 hinged to one end facing the central support column 28. Both supporting pivots 29 are fixedly connected to an auxiliary rotating plate 26. The ends of the two supporting plates 41 opposite to the central support column 28 are respectively hinged to the outer peripheries of both ends of a supporting column 45. A foot pedal 44 is fixedly connected to the center of the supporting column 45. The upper side of the foot pedal 44 is roughened to maintain the comfort of the user. One end of a power connecting plate 46 is hinged to one end of each of the two edges of the supporting column 45. The other end of each power connecting plate 46 is hinged to a power hinge pin 414. The two power hinge pins 414 are respectively fixedly connected to the opposite edges of two rotating disks 47. The rotating disks 47 can move in both directions and provide rotational force assistance during rotation. This exercise allows for effortless ankle and foot training. Two rotating discs 47 are each fixedly connected to a rotating shaft 416 at their center. The two rotating shafts 416 are rotatably connected to the opposite sides of two auxiliary sliders 49. Two torsion springs 48 are fixedly connected to the ends of the rotating discs 47 and the auxiliary sliders 49, respectively. The torsion springs 48 are respectively sleeved on the two rotating shafts 416. The torsion springs 48 provide rotational force, causing the rotating discs 47 to return to their original rotation. This return rotation drives the power connecting plate 46 upwards, which in turn drives the bearing column 45, causing the foot pedal 44 to push the exerciser's ankle upwards. This provides some assistance to the exerciser, preventing them from giving up due to the difficulty of ankle and foot training, thereby increasing their confidence and motivation.

[0028] An adaptable elongated hole 42 is provided at the hinge joint between the bearing connecting plate 41 and the bearing column 45. The adaptable elongated hole 42 is evenly provided with limiting teeth 417. An adaptable connecting sleeve 43 is provided at the connection between the bearing connecting plate 41 and the bearing column 45. The adaptable connecting sleeve 43 is fixed on the bearing column 45. Two auxiliary sliders 49 are slidably connected by an auxiliary sliding groove 210 and a reinforcing connecting column 211, thereby maintaining the relative position stability of the auxiliary sliders 49 and thus maintaining the stability of the structure. The reinforcing connecting column 211 is fixed on the inner wall of the auxiliary sliding groove 210. The auxiliary sliding groove 210 is opened on the left and right sides of the auxiliary rotating plate 26. Both auxiliary sliders 49 are fixedly connected to an adjustment frame 413 at their lower ends. The adjustment frame 413 is threadedly connected to an adjustment screw 412, which allows the exerciser to adjust the screw according to their foot size. It also allows the exerciser to choose whether to use the pedal 44 according to their needs. The adjustment screw 412 is rotatably connected to a first connecting seat 411 and a second connecting seat 415 at both ends. The first connecting seat 411 and the second connecting seat 415 are fixedly connected to the lower side of the auxiliary rotating plate 26. The rear end of the adjustment screw 412 is fixedly connected to a second turntable 410.

[0029] The auxiliary slide 210 and auxiliary slider 49 are matching dovetail shapes, and the limiting tooth 417 is made of hard rubber, thus ensuring that the adapter sleeve 43 can be adjusted within the adapter long slot. At the same time, it provides stable thrust when the pedal 44 assists in the exercise. When thrust is needed for assistance, the pedal 44 can be moved away from the end of the central support 28, thus preventing the pedal 44 from providing assistance and affecting the high-intensity foot and ankle exercise. The adapter sleeve 43 is a ring with a concave cross section, thus maintaining the connection stability of the structure.

[0030] The operation steps of this invention are as follows: When the exerciser needs to exercise, the elastic blocks 11 first connect to the staff's armpits. When the two elastic blocks 11 are clamped, they will cause the two arc-shaped blocks to move accordingly. During the movement of the two arc-shaped blocks, the two stabilizing plates 13 will drive the two movable columns 14 to move accordingly. During the movement of the two movable columns 14, the two limiting plates 15 will drive the two storage cylinders 16 to move. The cooperation between the movable columns 14 and the storage cylinders 16 can accommodate exercisers of different heights. The limiting plates 15 set on the movable columns 14 maintain the connection between the movable columns 14 and the storage cylinders 16, and the relative sealing between the limiting plates 15 and the storage cylinders 16 can also provide a certain degree of damping, thereby maintaining the exerciser's comfort during use. The support function of the support system can improve the safety of the exerciser to a certain extent. During the movement of the two storage cylinders 16, the two follower sliders 66 will move synchronously. During the synchronous movement of the two follower sliders 66, they will be limited by the follower slide grooves 67 opened on the base plate 68. At the same time, because the armpit is close to the shoulder, the two follower sliders 66 can be moved to a position close to the exerciser's shoulder. That is, the distance between the two central pillars 28 can be adjusted to a distance close to the width of the exerciser's shoulder. This allows different exercisers to quickly adjust the distance between the two central pillars 28 according to their own body shape, so that the distance between the two central pillars 28 is adjusted to the width of the exerciser's shoulder, thereby maintaining the quality of the exerciser's subsequent ankle strength repair training. During the sliding of the two follower sliders 66 within the follower groove 67, the lower ends of the two protective ropes 62 will be driven to move by the two second hinge pins. During the process of the two stabilizing plates 13 approaching each other, the upper ends of the two protective ropes 62 will be driven to move by the two first connecting pins 61. During this process, the relative position of the two protective ropes 62 will be ensured by the central hinge pin 63 connected at the center of the two protective ropes 62. This will provide protection and obstruction during the exercise, thereby reducing the risk of falls caused by the forward tilt due to the support slippage of the toes, and further improving the safety of the exerciser during the exercise process. When the exerciser's armpit is connected to the elastic block 11, the exerciser's hand can pass through the through slots 51 opened on the two stabilizing plates 13. Then the exerciser's hand can hold the grip post 55 for support. During this process, the grip post 55 will be supported by the vertical hole 56 opened on the stabilizing plate 13, the vertical post 52 and the adapter block 54, thus providing the exerciser with a more comfortable exercise state. In order to facilitate the use of exercisers with different arm lengths, an adaptation spring 53 is sleeved on the outside of the vertical post 52, and the two ends of the adaptation spring 53 are fixedly connected to the adapter block 54 and the opposite side of the stabilizing plate 13, thus accommodating exercisers with different arm lengths within a certain range. At the same time, it will also provide a certain upward force to help the exerciser stabilize their own state, thereby improving the safety of the exerciser during the exercise process to a certain extent. After the distance between the two central pillars 28 is adjusted to the width of the exerciser's shoulders, the exerciser's toes can step on the top plates 21 set on the upper ends of the two central pillars 28. Then, the two first turntables 38 can control the rotation of the two adjusting screws 33. After the two adjusting screws 33 rotate, they will cooperate with the two adjusting cylinders 32 to make the two limiting slide plates 31 have a tendency to move. Then, the two limiting slide plates 31 will slide by the limitation of the limiting slide groove 27. During the sliding of the limiting slide plates 31, the two hinge seats 1 36 will drive the telescopic connecting plate 34 to unfold or retract. During the unfolding or retracting of the telescopic connecting plate 34, the hinge seat 2 37 fixedly connected to the top plate 21 will be used for auxiliary positioning. During the unfolding or retracting of the telescopic connecting plate 34, the cooperating connecting plate 35 will move synchronously. During the movement of the cooperating connecting plate 35, it will slide to unfold or retract in cooperation with the cooperating through groove 22, so that the top plate 21 and the cooperating connecting plate 35 can form a stepping surface of different lengths, so that different exercisers can adjust the use according to their own foot size. Two first turntables 38 control the rotation of two adjusting screws 33. After the two adjusting screws 33 rotate, they cooperate with the two adjusting cylinders 32 to make the two limiting slide plates 31 have a tendency to move. Then, the two limiting slide plates 31 will slide by being restricted by the limiting slide groove 27. During the sliding of the limiting slide plates 31, they will drive the two hinge seats 1 36 to drive the telescopic connecting plate 34 to unfold or retract. During the unfolding or retracting process, the telescopic connecting plate 34 will use the hinge seat 2 37 fixedly connected to the top plate 21 for auxiliary positioning. During the unfolding or retracting process, the telescopic connecting plate 34 will synchronously drive the mating connecting plate 35 to move. During the movement of the mating connecting plate 35, it will interact with the mating through groove 2. 2. Coordinate the sliding expansion or contraction, and then the exerciser can adjust the stepping surface according to their own foot and ankle condition. In this way, when the exerciser moves up and down with the toes as the support point, the part of the toes that is supported can be changed. That is, the amount of force on the toes will negatively affect the amount of force on the ankle. That is, when the toes bear more force, the ankle bears less force, which is suitable for the initial exercise. When the toes bear less force, the ankle bears more force, which is suitable for the subsequent high-intensity exercise. This gradual adjustment makes it easy for staff to carry out progressive strength training for foot and ankle repair. During ankle strength recovery training, the toes can step on the top plate 21 to rotate. The rotation of the top plate 21 is assisted by the top ring groove 23 at the upper end of the central support 28, which allows the top plate 21 to easily rotate under force. This helps the trainee change the state of the toes, thereby performing ankle strength recovery training from multiple angles and maintaining a relatively high quality ankle strength recovery training. During the rotation of the top plate 21, it is also supported by the cooperation of the through groove 22, the connecting plate 35, the synchronization block 213, the auxiliary rotating plate 26, the auxiliary ring 24, and the auxiliary ring groove 25. This allows the contact surface between the trainee's toes and the connecting plate 35 and the top plate 21 to be easily rotated, which to a certain extent increases the rotational force that the ankle can withstand during the exercise, thus maintaining a more comprehensive ankle strength recovery training. After the exerciser's toes step onto the top plate 21 and the connecting plate 35, the ankle will step onto the pedal 44. The pedal 44 will then drive the power connecting plate 46 downwards via the support column 45. During this downward movement, the power connecting plate 46 will drive the rotary disc 47 to rotate via the power hinge pin 414. The rotary disc 47 will be supported by the rotary shaft 416 during its rotation, thus causing the power connecting plate 46 and the rotary disc 47 to be in a position similar to... Figure 13In this state, and during the rotation of the rotary disk 47, it will overcome the torque generated by the cooperation of the auxiliary slider 49 and the rotary torsion spring 48. During this process, the bearing plate 41 and the supporting rotating pin 29 will also limit the bearing column 45 to maintain the relatively vertical arc movement of the pedal 44. At the same time, the adapter sleeve 43 and the adapter elongated hole 42 will also be used to control the downward force on the pedal 44. Figure 13 After reaching the desired state, the torsion spring 48 will apply rotational force to reset the rotary disc 47 and make it rotate. The reset rotation of the rotary disc 47 will drive the power connecting plate 46 to move upward, which will then drive the bearing column 45 to cause the foot pedal 44 to push the exerciser's ankle upward, thus providing some assistance to the exerciser. Afterward, the exerciser can cooperate with the upward movement of the ankle to carry out ankle strength recovery training. To accommodate different foot sizes of exercisers, the adjustment screw 412 can be rotated by the second turntable 410. During the rotation of the adjustment screw 412, it is supported by the first connecting seat 411 and the second connecting seat 415, thereby maintaining the rotational stability of the adjustment screw 412. After the adjustment screw 412 rotates, it is limited by the cooperation of the adjustment connecting frame 413 and the two auxiliary sliders 49 with the auxiliary slide groove 210. At the same time, it is further limited by the reinforcement connecting column 211. Then, the two auxiliary sliders 49 can slide under the support of the auxiliary slide groove 210 and the reinforcement connecting column 211, which in turn can drive the two rotary shafts 416 to move. During the movement of the rotary shafts 416, the rotary disk 47 will be adjusted synchronously. Then, the adapter sleeve 43 set on the bearing column 45 overcomes the limitation of the limiting tooth 417 fixed in the adapter elongated hole 42, and slides in the adapter elongated hole 42 to correspond to the adjustment position of the rotary disk 47, thereby adapting to different foot sizes of exercisers.

It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
