Abstract
Description
Technical Field
[0001] This utility model relates to the field of rehabilitation equipment technology, and more specifically, to a portable ankle joint rehabilitation training device. Background Technology
[0002] The ankle is the smallest joint at the end of the three major joints of the lower limb. Although the ankle is directly connected to the foot, the surrounding muscles are not as strong as those of the hip and knee joints. The main range of motion of the ankle includes dorsiflexion, plantar flexion, eversion, inversion, and rotation, especially during the push-off phase of jumping movements, where the ankle joint plays a crucial role, and its strength directly determines the stability of the movement. It is precisely because of the frequent use of the ankle in training and the relatively weak surrounding muscles that the ankle is highly susceptible to injury during training.
[0003] Ankle rehabilitation devices are suitable for improving joint stiffness, preventing muscle atrophy, muscle adhesions, and ligament adhesions in the affected leg muscles, promoting venous return and reducing swelling after surgery. They can also prevent deep vein thrombosis in the lower extremities, improve muscle strength and joint range of motion, reduce adhesions in surrounding tissues, increase the strength of muscles around the joint, improve joint function, facilitate muscle training, and work in conjunction with other rehabilitation therapies to restore limb function.
[0004] However, most ankle rehabilitation devices currently available cannot adjust the range and intensity of training. Each person's ankle injury severity, recovery speed, and rehabilitation needs are different. If the device cannot adjust the training range, it cannot create a personalized rehabilitation plan based on the individual's specific situation, thus affecting the rehabilitation outcome. Furthermore, as rehabilitation progresses, the intensity required by the individual will change. A non-adjustable device cannot adapt to these changes, potentially leading to rehabilitation progress that is too fast or too slow, both of which are detrimental to the individual's recovery.
[0005] Therefore, this utility model proposes a portable ankle joint rehabilitation training device to solve the above problems. Summary of the Invention
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a portable ankle joint rehabilitation training device, which solves the problems mentioned in the background art by setting an amplitude adjustment part and an intensity adjustment part.

An elastic mechanism is provided inside the second outer shell for automatic reset of the pedal. A pressure plate located in the middle of the elastic mechanism is provided on the second rotating shaft. A pressurizing mechanism is provided on the second outer shell for adjusting the initial state of the elastic mechanism, thereby adjusting the training intensity of the rehabilitation personnel.
[0011] Preferably, the shielding mechanism includes two rotating rings rotatably connected to the first housing, both of the swing plates are located inside the rotating rings, and each rotating ring has a baffle on its inner surface, the baffle being able to contact the swing plate on the corresponding side.
[0012] Preferably, the first outer shell has two sliding grooves corresponding to the rotating ring. Each sliding groove is provided with a movable plate. One end of each movable plate is fixed to the rotating ring on the corresponding side, and the other end is provided with a fixing bolt located outside the first outer shell.

[0016] Preferably, the leg support includes two symmetrically distributed connecting plates, which are hinged to the pedal, and two symmetrically distributed support plates are provided between the two connecting plates.
[0017] Preferably, the lower part of the connecting plate is stepped, which is used to align the upper part of the connecting plate with the upper part of the pedal to increase the comfort of the rehabilitation personnel.
[0018] Preferably, both the first and second rotating shafts are provided with keyways to prevent relative rotation between the swing plate and the first rotating shaft, and between the pressure plate and the second rotating shaft, thereby improving the adjustment accuracy.
[0019] Preferably, the free ends of the leg strap and the foot strap are provided with Velcro, and the two Velcro straps on the same side can be attached together.
[0020] The technical effects and advantages of this utility model are as follows:

The blocking mechanism limits the swing range of the swing plate through the rotating ring and the baffle, thereby achieving precise control of the amplitude. This allows the rehabilitation personnel to easily swing their feet to the expected amplitude, preventing the swing amplitude from being too small and affecting the rehabilitation effect, while avoiding the swing amplitude from being too large and damaging the ankle joint. The design of the slide and the movable plate makes the adjustment of the blocking mechanism more convenient, and the fixing bolts ensure the stability after adjustment. Rehabilitation personnel can adjust the training amplitude of the ankle joint according to their own rehabilitation progress and the doctor's guidance to achieve personalized rehabilitation training.
[0023] 3. This utility model is equipped with an intensity adjustment unit, which provides adjustable resistance intensity through the combination of a guide ring, sleeve, and elastic element in the elastic mechanism. Users can adjust the pressure of the pressure block on the sleeve through the pressure mechanism, thereby changing the compression degree of the elastic element and adjusting the resistance intensity. As the rehabilitation process progresses, the training intensity of the device can be adjusted according to the rehabilitation intensity required by the individual, avoiding excessively fast or slow rehabilitation progress, which is beneficial to the individual's recovery. The design of the pressure bolt makes the adjustment of resistance intensity more intuitive and convenient. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] Example 1
[0038] In practical use, it has been found that the degree of ankle injury, recovery speed and rehabilitation needs of each rehabilitation patient are different. If the rehabilitation device cannot adjust the range of rehabilitation training, it is impossible to formulate a personalized rehabilitation plan according to the specific situation of the rehabilitation patient, thereby affecting the rehabilitation effect. This embodiment is invented to solve the above problems.
[0039] Please see Figures 1 to 5 As shown, a portable ankle joint rehabilitation training device according to an embodiment of the present invention includes a device body 1 and an amplitude adjustment part 2. The device body 1 includes a pedal 101, and a leg support 102 is hinged to the upper end of the pedal 101. Two symmetrically distributed foot fixing straps 103 are provided on the pedal 101, and the foot fixing straps 103 are used to fix the pedal 101 to the foot of the rehabilitation personnel. Two symmetrically distributed leg fixing straps 104 are provided on the leg support 102, and the leg fixing straps 104 are used to fix the leg support 102 to the leg of the rehabilitation personnel.
[0040] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the amplitude adjustment unit 2 includes a first housing 201 disposed at the hinge of the leg support 102 and the pedal 101. A first rotating shaft 202 is rotatably connected to the first housing 201. The free end of the first rotating shaft 202 passes through the leg support 102 and is fixed to the pedal 101. Two symmetrically distributed swing plates 203 are provided on the first rotating shaft 202. A blocking mechanism 204 is provided inside the first housing 201. The blocking mechanism 204 is used to change the swing amplitude of the swing plates 203.
[0041] Please see Figure 4 and Figure 5 As shown, the shielding mechanism 204 includes two rotating rings 2041 that are rotatably connected to the first housing 201. Both swing plates 203 are located inside the rotating rings 2041. Each rotating ring 2041 has a baffle 2042 on its inner surface. The baffle 2042 can contact the swing plate 203 on the corresponding side.
[0042] Please see Figure 5As shown, the first outer shell 201 has two grooves 2043 corresponding to the rotating ring 2041. Each groove 2043 is provided with a movable plate 2044. One end of each movable plate 2044 is fixed to the rotating ring 2041 on the corresponding side, and the other end is provided with a fixing bolt 2045 located outside the first outer shell 201. The end of the fixing bolt 2045 can contact the outer surface of the first outer shell 201.
[0043] Please see Figure 3 As shown, the leg support 102 includes two symmetrically distributed connecting plates 1021, which are hinged to the pedal 101, and two symmetrically distributed support plates 1022 are provided between the two connecting plates 1021.
[0044] When using the device, the rehabilitation personnel need to first fix the training device to their ankle, place the sole of their foot against the pedal 101, place their lower leg between the two symmetrically distributed connecting plates 1021, and place the back of their lower leg against the two support plates 1022. Then, fasten the Velcro at the free ends of the two foot fixing straps 103 together, and at the same time, fasten the Velcro at the free ends of the two leg fixing straps 104 together, thereby fixing the main body 1 of the device to the ankle.
[0045] The rehabilitation personnel swing their feet up and down, driving the pedal 101 to swing up and down. The pedal 101 drives the first rotating shaft 202 to rotate in both directions. The first rotating shaft 202 drives the two swing plates 203 to swing in both directions. The keyway 4 on the first rotating shaft 202 is used to prevent relative rotation between the swing plates 203 and the first rotating shaft 202.
[0046] When the rehabilitation personnel press down on the pedal 101, the first rotating shaft 202 drives the two swing plates 203 to swing clockwise until the upper swing plate 203 contacts the upper baffle 2042, and the pedal 101 swings clockwise to its extreme point. At this time, the rehabilitation personnel need to lift their feet up. Then, the first rotating shaft 202 drives the two swing plates 203 to swing counterclockwise until the lower swing plate 203 contacts the lower baffle 2042, and the pedal 101 swings counterclockwise to its extreme point.
[0047] When the training range of the rehabilitation personnel needs to be adjusted, the two fixing bolts 2045 are rotated counterclockwise so that the ends of the fixing bolts 2045 do not contact the first outer shell 201. At this time, the movable plate 2044 can slide freely in the slide groove 2043. The rehabilitation personnel can pull the two movable plates 2044 to slide in the slide groove 2043. The movable plate 2044 drives the rotating ring 2041 to rotate, and the rotating ring 2041 drives the baffle 2042 to rotate, thereby adjusting the position of the two baffles 2042.
[0048] When the two baffles 2042 swing to the right, the swing space of the two swing plates 203 increases, that is, the training amplitude increases. When the two baffles 2042 swing to the left, the training amplitude decreases. Moreover, the two baffles 2042 can be adjusted independently, so as to suit rehabilitation personnel with different up-and-down swing amplitudes of the feet. After adjustment, rotate the two fixing bolts 2045 clockwise so that the ends of the fixing bolts 2045 contact the outer surface of the first shell 201. At this time, the two baffles 2042 cannot swing freely, and the rehabilitation personnel can carry out rehabilitation training at the current training amplitude.
[0049] Rehabilitation patients train their ankle joints by swinging their feet up and down, which accelerates the recovery process. The two baffles 2042 allow patients to swing their feet easily to the expected range, preventing the swing range from being too small and affecting the rehabilitation effect, while also avoiding the swing range from being too large and damaging the ankle joint.
[0050] Example 2
[0051] In actual use, it was found that although the amplitude adjustment unit 2 can adjust the training amplitude of the rehabilitation personnel, the rehabilitation intensity required by the rehabilitation personnel will also change as the rehabilitation process progresses. The non-adjustable rehabilitation device cannot adapt to this change, which may lead to the rehabilitation progress being too fast or too slow, both of which are not conducive to the recovery of the rehabilitation personnel. Further improvements were made based on the above embodiments.
[0052] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the main body 1 of the device also includes an intensity adjustment unit 3. The intensity adjustment unit 3 includes a second outer shell 301 disposed at the hinge of the leg support 102 and the pedal 101. A second rotating shaft 302 is rotatably connected to the second outer shell 301. The free end of the second rotating shaft 302 passes through the leg support 102 and is fixed to the pedal 101. An elastic mechanism 303 is provided inside the second outer shell 301. The elastic mechanism 303 is used for the automatic reset of the pedal 101. A pressure plate 304 located in the middle of the elastic mechanism 303 is provided on the second rotating shaft 302. A pressure mechanism 305 is provided on the second outer shell 301. The pressure mechanism 305 is used to adjust the initial state of the elastic mechanism 303, thereby adjusting the training intensity of the rehabilitation personnel.
[0053] Please see Figure 6 and Figure 7 As shown, the elastic mechanism 303 includes a guide ring 3031 fixed inside the second housing 301, a pressure plate 304 slidably connected to the guide ring 3031, two symmetrically distributed sleeves 3032 sleeved on the guide ring 3031, and two elastic elements 3033 sleeved on the guide ring 3031 located between the sleeves 3032 and the pressure plate 304. The elastic elements 3033 always drive the pressure plate 304 back to the initial position.
[0054] Please see Figure 6 and Figure 7 As shown, the pressurizing mechanism 305 includes a pressure block 3051 disposed in the second housing 301. Two symmetrically distributed connecting rods 3052 are hinged on the pressure block 3051, and the free ends of the connecting rods 3052 are hinged to the sleeves 3032 on the corresponding sides.
[0055] Please see Figure 7 As shown, the second housing 301 is provided with a pressure bolt 3053, and the end of the pressure bolt 3053 is in contact with the pressure block 3051.
[0056] Based on the above embodiments, during use, the rehabilitation personnel drive the pedal 101 to swing up and down repeatedly with their feet. When the pedal 101 swings up and down repeatedly, it also drives the second rotating shaft 302 to rotate in both directions. The second rotating shaft 302 drives the pressure plate 304 to swing in both directions. The keyway 4 on the second rotating shaft 302 is used to prevent relative rotation between the pressure plate and the second rotating shaft. When the pressure plate 304 swings, it squeezes the elastic element 3033 on the guide ring 3031. That is, when the rehabilitation personnel swing their feet up and down repeatedly, they need to overcome the elastic force of the elastic element 3033, thereby accelerating the rehabilitation speed of the rehabilitation personnel.
[0057] When the training intensity of the rehabilitation personnel needs to be increased, the pressure bolt 3053 needs to be rotated clockwise. The end of the pressure bolt 3053 drives the pressure block 3051 to move downward. The pressure block 3051 drives the two connecting rods 3052 to move downward. The two connecting rods 3052 drive the two sleeves 3032 to slide downward along the guide ring 3031. When the sleeves 3032 slide, they will squeeze the elastic element 3033, increasing the initial elastic force of the elastic element 3033. The rehabilitation personnel's feet need to exert more force to overcome the elastic force of the elastic element 3033, thereby increasing the training intensity of the ankle joint.
[0058] When the training intensity of the rehabilitation personnel needs to be reduced, simply rotate the pressure bolt 3053 counterclockwise. The end of the pressure bolt 3053 moves upward, and the pressure block 3051 loses the function of the pressure bolt 3053. The two elastic elements 3033 start to drive the two sleeves 3032 to slide upward along the guide ring 3031. The two sleeves 3032 drive the two connecting rods 3052 to move upward. The two connecting rods 3052 together drive the pressure block 3051 to move upward and re-contact with the pressure bolt 3053. The initial elastic force of the elastic element 3033 decreases, thereby reducing the training intensity of the ankle joint.
[0059] By adjusting the intensity of ankle joint training, it can be adapted to rehabilitation personnel at different stages of rehabilitation, which helps to accelerate their recovery.
[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
