Description

Technical Field

[0001] This utility model relates to the field of therapeutic rehabilitation exercise technology, and in particular to a foldable KOA-PT training device. Background Technology

[0002] Knee osteoarthritis (KOA), also known as proliferative knee arthritis or senile knee arthritis (commonly referred to as "old cold legs"), is a chronic joint disease characterized by progressive degeneration of joint tissues. The earliest and most significant pathological changes occur in the articular cartilage layer, subsequently developing into secondary lesions such as subchondral bone cysts and osteophyte formation at the joint margins. As the disease progresses, the articular surface structure gradually deteriorates and deformities occur, ultimately leading to persistent and worsening pain and impaired joint movement. This series of degenerative changes constitutes the typical pathological progression of KOA.

[0003] The "Chinese Clinical Practice Guidelines for Osteoarthritis Pain Management (2020)" lists exercise therapy as a Grade 1A recommendation for KOA treatment. Leg-swinging exercises can effectively relieve knee pain. The principle behind this was first elucidated in patent CN113952677B: hip joint swinging drives non-contact movement of the knee joint, causing periodic contraction and relaxation of the synovial bursa, resulting in alternating pressure changes within the joint cavity and promoting synovial fluid circulation. This process accelerates the clearance of inflammatory factors, enhances cartilage nutrition, thereby relieving pain and promoting repair. This discovery provides an important theoretical basis for the rehabilitation of knee osteoarthritis.

[0004] Leg-swinging exercises, as a non-weight-bearing rehabilitation method, not only have excellent therapeutic effects on knee pain, but also provide unique benefits to the lumbar spine, hip joints, and cardiopulmonary function. Through dynamic swinging, leg-swinging exercises involve the contraction and relaxation of the back muscles (such as the erector spinae and quadratus lumborum), promoting local blood circulation and relieving muscle stiffness caused by prolonged sitting or static postures. Furthermore, maintaining a long-term habit of leg-swinging exercises can enhance lumbar spine stability, reduce intervertebral disc pressure, improve lumbar spine mobility, and prevent degenerative diseases.

[0005] Leg-swinging exercises also have a rehabilitative effect on the hip joint. Dynamic stretching leg-swinging exercises can improve the extensibility of the hip joint capsule and surrounding ligaments (such as the iliofemoral ligament and ischiofemoral ligament), improving range of motion in flexion and extension directions. This is particularly suitable for people who sit for long periods, preventing "hip stiffness syndrome" caused by hip joint capsule contracture. The muscles around the hip joint (gluteus maximus, iliopsoas, quadriceps, hamstrings) contract alternately during leg-swinging, enhancing muscle coordination and correcting anterior pelvic tilt or hip instability caused by muscle imbalances (such as shortening of the iliopsoas muscle and weakness of the gluteal muscles due to prolonged sitting). Furthermore, dynamic swinging stimulates the synovium of the hip joint to secrete synovial fluid, lubricating the joint surfaces and reducing cartilage wear; it prevents and treats complications such as muscle atrophy and joint stiffness, maintains and improves joint range of motion, and enhances muscle strength, endurance, balance, and coordination, significantly improving patients' daily living abilities.

[0006] Leg-swinging exercises are non-weight-bearing lower limb movements involving resistance exercises of the central muscle groups. Through coordinated multi-directional and multi-joint movements of the lower limbs, this method has become a preferred and highly effective treatment for lumbar spine diseases (including lumbar disc bulging / protrusion, lumbar muscle strain, lumbar muscle soreness, lumbar muscle atrophy, etc.), hip joint diseases (covering hip arthritis, femoral head ischemia, rehabilitation after total hip arthroplasty, etc.), knee joint diseases (such as knee osteoarthritis KOA, perikal muscle atrophy, patellar tendinitis, knee edema, etc.), as well as various postoperative and neurological diseases (such as post-ankle trimalleolar fracture, sequelae of poliomyelitis, sequelae of cerebral palsy, rehabilitation after stroke, etc.). This therapy achieves an integrated therapeutic effect of pain relief, functional recovery, and motor capacity reconstruction through central muscle group activation and multi-joint linkage training in a non-weight-bearing state, providing a safe, comprehensive, and efficient rehabilitation solution for various musculoskeletal diseases and neurological sequelae.

[0007] Existing leg-swinging rehabilitation devices typically employ a fixed structural design, including a base to support the user's torso and an arm support plate connected by a rigid bracket. The base must allow sufficient space for leg swing, while the upper bracket must extend to an appropriate height to provide arm support, ensuring balance and stability during training. This structural design results in a bulky overall device, making transportation difficult and storage in space-constrained environments such as homes or small rehabilitation facilities, severely limiting its ease of use and applicability. Utility Model Content

[0008] To address the problems of complex structure and large size in existing technologies, this invention provides a compact and easy-to-store foldable KOA-PT training device. The device adopts an integrated design, and through optimized mechanical structure layout, significantly reduces the device size while ensuring the integrity of training functions.

[0009] To achieve the above objectives, this application presents a foldable KOA-PT training device, characterized in that it includes a base, a vertical support, and an upper support plate. The vertical support includes two support columns, the lower ends of which are fixedly connected to the base. A standing area for standing is provided between the base and the two support columns. The upper support plate is rotatably connected coaxially to the upper ends of the two support columns between an unfolded position and a folded position. The upper support plate is provided with an upper limb support portion. When the upper support plate is rotated relative to the support columns to the unfolded position, it is fixedly placed horizontally on the upper end of the support columns, and the upper limb support portion is located above the standing area. When the upper support plate is rotated relative to the support columns to the folded position, it is vertically close to the side wall of the support columns.

[0010] By adopting the above technical solution, firstly, unlike the existing multi-functional support frame that provides separate support for the elbows or armpits on both sides, this application uses a single plate structure for the upper support plate, with the upper limb support parts all located on the upper support plate. Thus, compared to the cumbersome process of separate folding and storage of multi-functional support frames, the folding design of this application only requires rotating and folding the entire upper support plate, making it convenient to operate and highly efficient to store. From the perspective of the support and weight-reduction functions of the upper support plate itself, active leg-swinging KOA-PT training places higher demands on upper limb support and weight reduction, requiring greater weight-reduction support force. Existing separate multi-functional support frames, due to their low structural stability, tend to wobble or sway when supporting active KOA-PT training, resulting in insufficient safety and support stability. In contrast, the entire upper support plate of this application, with its integrated rigid structure, offers high stability and safety, good adaptability to the high weight-reduction requirements of active KOA-PT training, and high load-bearing capacity. Furthermore, separate multi-functional support frames require separate height adjustments on both sides when bearing weight, which can easily lead to inconsistent heights. The integrated upper support plate, however, allows for unified height adjustment, making operation convenient and ensuring high consistency in upper limb support height.

[0011] Secondly, in this application, a foldable KOA-PT training device features an upper support plate that can be rotated to an unfolded position and a folded position. When KOA-PT rehabilitation training is required, the upper support plate is rotated relative to the support column to the unfolded position. The upper support plate is fixedly positioned horizontally at the upper end of the support column, with the upper limb support located above the standing area. The user stands in the standing area, supporting themselves with their forearm or arm on the upper limb support to maintain a stable posture, and swings the affected leg for rehabilitation training with their own effort or the assistance of other devices. When not in use for training, the upper support plate is rotated to the folded position, close to the side wall of the support column. In this position, the upper support plate can be folded vertically or diagonally in any direction that minimizes space occupation. This effectively reduces the horizontal space occupied by the entire foldable KOA-PT training device, minimizing interference with other objects during transport and placement, making the device convenient for use and storage in various scenarios such as home, hospital, office, and long-distance high-speed rail. It is worth noting that when a user stands in the standing area, the standing area can be equipped with a step stool with a height difference, or the user can tilt the body to stand on one leg and swing the other leg for leg swinging rehabilitation training.

[0012] As an example of this application, the width of the upper support plate is less than or equal to the spacing between the support columns, and the two sides of the upper support plate are rotatably connected to the upper end of the support columns.

[0013] By adopting the above technical solution, a specific rotational connection method between the upper support plate and the support column is realized. The upper support plate is connected to the support column through both sides, thereby improving the rotational freedom and flexibility of the upper support plate.

[0014] Optionally, when the upper support plate rotates relative to the two support columns to the folded position, the upper support plate is located between the two support columns.

[0015] By adopting the above technical solution, the upper support plate is stored between the support columns, which saves space utilization and improves the integration and compactness of the device. The upper support plate also provides a certain support to the support columns, which improves the overall structural stability and center of gravity balance of the device, making it easier for the device to maintain stability and balance when moving, preventing falls, and making it easy to push, thus improving the storage and mobility of the device.

[0016] As an example of this application, the width of the upper support plate is greater than the spacing between the support columns, and the lower surface of the upper support plate is rotatably connected to the upper end of the support column.

[0017] By adopting the above technical solution, another specific method of rotating connection between the upper support plate and the support column is achieved. Since the upper support plate plays an important role in supporting the upper limbs of the user during active KOA-PT training, its support stability plays a crucial role in the overall safety and stability of the device. Firstly, the support column provides better upward support to the lower surface of the upper support plate, thereby balancing the user's upper limb weight and effectively improving the overall stability and safety of the device. Secondly, it also reduces the lateral distance between the support columns, thus reducing the overall lateral distance of the device and further reducing the space occupied by the device. Thirdly, since the width of the upper support plate is greater than the spacing between the support columns, the support columns act as a limit to the rotation of the upper support plate and also as an indicator of the folding position. When the upper support plate needs to be rotated to the folding position, it only needs to be rotated until it is blocked by the side wall of the support column, which is convenient to operate. Furthermore, when moving the device in the folded storage state, the side wall of the support column can provide support for the upper support plate, improving the structural stability of the device and thus improving the stability and convenience of movement.

[0018] Optionally, when the upper support plate rotates relative to the two support columns to the folded position, the lower surface of the upper support plate is in contact with the side wall of the support column.

[0019] By adopting the above technical solution, when the lower surface of the upper support plate is attached to the side wall of the support column, the stability and integration of the device in the folded state can be further improved. It also improves the support of the side wall of the support column to the upper support plate when the device is moved in the folded storage state, thereby improving the structural stability of the device and thus improving the stability and convenience of movement.

[0020] As an example of this application, the upper end of the support column corresponds to the upper limb support part.

[0021] By adopting the above technical solution, the upward support provided by the support column can balance the downward load on the user's upper limbs, effectively improving the overall stability of the device, training safety, and device durability.

[0022] Optionally, the upper end of the support column is rotatably connected to the upper support plate via a bearing. In this application, a bearing is directly used to achieve the rotatable connection of the upper support plate around the upper end of the support column. The bearing serves both load-bearing and rotational functions.

[0023] Optionally, when the upper support plate is rotated to the folded position relative to the support column, the upper support plate is vertically positioned. This vertical positioning, close to the side wall of the support column, reduces the space it occupies.

[0024] As an example of this application, when the upper support plate rotates relative to the support column to the unfolded position, the upper support plate is fixed horizontally at the upper end of the support column by wedge blocks. The wedge blocks achieve a stable and fixed horizontal position of the upper support plate.

[0025] As an example of this application, the rotation directions of the upper support plate to the unfolded position and to the folded position are opposite. The unfolded position is the maximum rotation limit position, and the direction of the rotation limit action on the upper support plate is the same as the direction in which the upper support plate bears the weight of the user's upper limbs. By adopting the above technical solution, the rotation limit can quickly reach the unfolded position, and the stability of the unfolded position can be achieved without additional fixing parts, improving the operating efficiency and convenience of the device, as well as the stability of the device.

[0026] Optionally, the vertical support is provided with a telescopic mechanism that can be extended and retracted in the vertical direction, and the working end of the telescopic mechanism is fixedly connected to the base.

[0027] Optionally, the upper support plate includes a U-shaped opening, and the upper limb support is located on both sides of the U-shaped opening.

[0028] Optionally, elbow support blocks are provided in the upper limb support portions located on both sides of the U-shaped opening.

[0029] Optionally, the elbow support block is provided with an arc-shaped support groove.

[0030] Optionally, the upper support plate is provided with a grip bar that matches the upper limb support part. The vertical distance between the grip bar and the upper support plate is greater than the vertical distance between the top of the elbow support block and the upper support plate. When the user swings their leg, they grip the grip bar for hand support, with their elbows touching the upper limb support part. The triangular mechanical structure formed by both hands gripping the grip bar and the elbow support can significantly improve upper body stability and enhance neuromuscular coordination during exercise.

[0031] Optionally, the upper support plate is provided with an item placement area on the side near the U-shaped opening, and a stop is provided on the side of the item placement area near the U-shaped opening.

[0032] Optionally, a safety latch is provided inside the U-shaped opening.

[0033] Optionally, the base is provided with a stroke detection mechanism, including a front detection rod and a rear detection rod. The front detection rod and the rear detection rod are rotatably mounted on both sides of the vertical support, and their relative angle with the vertical support is adjustable. The top of the front detection rod and the rear detection rod are both provided with sensors to detect whether the user's leg swing amplitude reaches the set requirements when performing KOA-PT exercise.

[0034] Optionally, both the front detection rod and the rear detection rod are telescopic rods.

[0035] Optionally, the stroke detection mechanism is provided in two sets, and is symmetrically arranged on both sides of the lower support.

[0036] In another embodiment of this utility model, a lower support base is further included. The lower support base is disposed in the standing area. The lower support base and the lower ends of the two support columns are rotatably connected coaxially between an open position and a retracted position. When the lower support base is rotated relative to the support columns to the open position, the lower support base is horizontally placed at the lower end of the support columns, and the upper support plate and the lower support base are located on the same side of the support columns. When the lower support base is rotated relative to the support columns to the retracted position, the lower support base is vertically arranged and close to the side wall of the support columns.

[0037] Optionally, when the lower support seat is rotated to the storage position relative to the support column, the lower support seat is located between the support columns.

[0038] This design saves space utilization and improves the integration and compactness of the device. The upper support plate also provides some support to the support column, which improves the overall stability and center of gravity balance of the device. This makes it easier for the device to maintain stability and balance when moving, prevents falls, and is easy to push, thus improving the device's storage and mobility.

[0039] Optionally, the upper support plate and the lower support base rotate in opposite directions to reduce the space occupied during storage.

[0040] Optionally, the lower support base is provided with two lifting pedals, which are symmetrically arranged with respect to the center line of the lower support base.

[0041] Optionally, the upper support plate is provided with a control panel and an emergency stop switch, and the lifting pedal is communicatively connected to the control panel.

[0042] Optionally, a folding bracket is provided on the side of the upper support plate away from the upper limb support.

[0043] Optionally, the lower support is provided with a receiving groove, a rotating screw is rotatably connected in the receiving groove, and a limiting groove matching the rotating screw is provided on the base.

[0044] Optionally, the base is provided with a pulley on the side away from the lower support, and the upper support plate is provided with a gripping groove at the bottom on the side away from the upper limb support.

[0045] Compared with the prior art, the present invention has at least the following advantages: When rehabilitation training is needed, the upper support plate is first adjusted by rotating and flipping it upwards relative to the vertical frame until it reaches a horizontal position. The user can then stand on one leg on the lower support seat (or an equivalent structure) after stepping onto the training device, maintaining a stable standing posture by supporting themselves with their forearm or arm on the upper support plate. They can then swing their affected leg for rehabilitation training using their own strength or with the help of other equipment. When not in use, the upper support plate is rotated downwards to a vertical position, and the lower support seat is rotated upwards to a vertical position. The base provides support, and both the lower support seat and upper support plate are adjusted to a vertical position that aligns with the vertical frame. This invention effectively reduces the horizontal space occupied by the entire foldable KOA-PT training device, minimizing interference with other objects during transport and placement. This makes the device easy to use and store in various scenarios, including home, hospital, office, and long-distance high-speed rail. It is easy to use, has a simple structure, adapts to various visual scenarios and multiple functions, occupies little space, and can facilitate leg-swinging therapy for a wide range of users in various scenarios.

Detailed Implementation

[0048] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Example 1 like Figure 1 and Figure 2 As shown, this utility model designs a foldable KOA-PT training device, including a base 1, a vertical support 2, and an upper support plate 3. The vertical support includes two support columns 21, the lower ends of which are fixedly connected to the base 1. A standing area a is provided between the base 1 and the two support columns 21. The upper support plate 3 is rotatably connected to the upper ends of the two support columns 21 coaxially between an unfolded position b and a folded position c. The upper support plate 3 is provided with an upper limb support part 31. When the upper support plate 3 is rotated relative to the support columns 21 to the unfolded position, the upper support plate 3 is fixedly placed horizontally on the upper end of the support columns, and the upper limb support part 31 is located above the standing area. When the upper support plate 3 is rotated relative to the support columns 21 to the folded position c, the upper support plate 3 is close to the side wall of the support columns 21.

[0050] Optionally, a lower support seat 11 is rotatably mounted on the base 1. The lower support seat 11 and the upper limb support part 31 are located on the same side of the vertical bracket 2, and their rotation axes are parallel to each other. The lower support seat 11 is located in the standing area a. The lower support seat 11 and the lower ends of the two support columns 21 are rotatably connected coaxially between an open position d and a retracted position e. When the lower support seat 11 rotates relative to the support columns 21 to the open position d, the lower support seat 11 is placed horizontally at the lower end of the support columns 21, and the upper support plate 3 is located on the same side of the support columns 21. When the lower support seat 11 rotates relative to the support columns 21 to the retracted position e, the lower support seat 11 is vertically positioned close to the side wall of the support columns 21, located between the support columns 21. The upper support plate 3 rotates in the opposite direction to the lower support seat 11, so that the space occupied during storage is smaller.

[0051] Using the foldable KOA-PT training device provided in this embodiment of the invention, when rehabilitation training is required, refer to Figure 1 First, adjust the upper support plate 3 and the lower support seat 11. Adjust the lower support seat 11 to the open position d, forming a standing area a on the top surface of the support seat 11, providing the user with corresponding standing space. Adjust the upper support plate 3 to the unfolded position b, where the upper support plate 3 is in a horizontal position. After stepping onto the training device, the user can stand on one leg on the lower support seat 11 and maintain a stable standing posture by supporting themselves with their forearm or arm at the upper limb support part 31 on the upper support plate 3. They can then swing their affected leg for rehabilitation training by applying their own strength or with the help of other equipment. When not in use for training, refer to... Figure 2 By rotating the upper support plate 3 in the reverse direction to the folding position c and the lower support base 11 in the reverse direction to the storage position e, the base 1 provides support. Both the lower support base 11 and the upper support plate 3 are adjusted to a vertical posture that fits against the upright bracket 2. This effectively reduces the horizontal space occupied by the entire foldable KOA-PT training device, minimizing interference with other objects during handling and placement. This makes the device easy to use and store in various scenarios such as home, hospital, office, and long-distance high-speed rail. It is convenient to use, has a simple structure, adapts to various visual scenarios and multiple functions, occupies little space, and can facilitate leg swinging therapy for a wide range of users in various scenarios.

[0052] Example 2 refer to Figure 3 Two support columns 21 are symmetrically connected at one end to both sides of the upper support plate 3, and at the other end to both sides of the base 1. By using two support columns 21 as the vertical support 2, multi-point connection and support are achieved from the left and right sides of the base 1 and the upper support plate 3, improving the stability of the connection and support and the overall service life. At the same time, with the two support columns 21 set on both sides, the space between the upper support plate 3 and the lower support seat 11 can be used as a leg-swinging training space for the patient, ensuring user comfort.

[0053] In one embodiment, the width of the upper support plate 3 is less than or equal to the distance between the support columns 21, and the two sides of the upper support plate 3 are rotatably connected to the upper ends of the support columns 21. When the upper support plate 3 is rotated relative to the two support columns 21 to the folded position c, the upper support plate 3 is located between the two support columns 21, which improves the storage and mobility of the entire device.

[0054] In another embodiment, the width of the upper support plate 3 is greater than the spacing between the support columns 21, and the lower surface of the upper support plate 3 is rotatably connected to the upper end of the support column 21. The upper end of the support column 21 corresponds to the upper limb support part 31. When the upper support plate 3 rotates relative to the two support columns 21 to the folded position c, the lower surface of the upper support plate 3 adheres to the side wall of the support column 21, saving the lateral space occupied by the entire device.

[0055] The upper end of the support column 21 corresponds to the upper limb support part 31. The upper end of the support column 21 is rotatably connected to the upper support plate 3 via a bearing, allowing the upper support plate to rotate around the upper end of the support column 21. The bearing serves both load-bearing and rotational functions. When the upper support plate 3 rotates relative to the support column 21 to the folded position c, the upper support plate 3 is vertically positioned. This vertical positioning, close to the side wall of the support column 21, reduces the space occupied. When the upper support plate 3 rotates relative to the support column 21 to the unfolded position b, the upper support plate 3 is horizontally fixed to the upper end of the support column 21 by a wedge block. The wedge block ensures the stable horizontal fixation of the upper support plate 3.

[0056] refer to Figure 3 and 4 In a preferred embodiment of this utility model, the vertical support 2 is provided with a telescopic mechanism that allows for vertical adjustment, and the working end of the telescopic mechanism is fixedly connected to the base 1. Exemplarily, based on embodiment 1, each support column 21 includes a telescopic support 211 connected to the base 1 at its lower end and a telescopic arm 212 that is telescopically mounted within the telescopic support 211 via a driving device. A rotating mechanism 213 is provided above the telescopic arm 212, and the bottom of the upper support plate 3 is connected to the rotating mechanism 213. The upper support plate 3 can be driven to rotate under the influence of an external control signal to adjust its posture relative to the support column 21. Depending on the user's height, the overall height of the upper support plate 3 can be adaptively adjusted by adjusting the relative length of the telescopic arm 212 extending from the telescopic support 211, ensuring the user can perform leg-swinging exercises in a comfortable standing posture, further improving user comfort.

[0057] Further, refer to Figure 5 The rotating mechanism 213 is a damped rotating mechanism that receives external electrical control signals. Its fixed end is connected to the top of the telescopic arm 212, while its rotating end is fixedly connected to the upper support plate 3 via a connector or other structure. After receiving the control signal, the damping shaft inside the rotating mechanism 213 drives the rotating end and the upper support plate 3 to rotate relative to the telescopic arm 212. After rotating to the correct position, the locking pin 2131 controls the fixing pin 2132 to engage with the rotating mechanism 213 for locking and limiting, thus preventing relative swaying.

[0058] Example 3 refer to Figures 1 to 3 In a preferred embodiment of this utility model, the upper support plate 3 includes a U-shaped opening 32, with upper limb support parts 31 located on both sides of the U-shaped opening 32. After the lower support seat 11 is adjusted to a horizontal position, its entire body is located below the U-shaped opening 32 on the upper support plate 3. The U-shaped opening 32 can locate the area on the lower support seat 11 for the patient to stand in, as well as the relative position of the upper limb support parts 31. After the user stands on the upper and lower support seats 11 and is in position, their upper body is located in the slotted space formed by the U-shaped opening 32. At this time, the arms and elbows can bend naturally and support the upper limb support parts 31 on both sides, so that the user can always maintain the correct leg-swinging posture with upright standing and arms supporting on both sides when swinging the legs, improving the standardization of leg-swinging training and the efficacy of leg-swinging therapy. It also ensures that the user's posture remains unchanged when switching legs, realizing that the upper support plate 3 provides stable support for the user when switching legs, improving the efficiency and stability of leg-swinging, and improving the consistency and training effect of leg-swinging training.

[0059] Furthermore, elbow support blocks 33 are provided inside the upper limb support sections 31 located on both sides of the U-shaped opening 32. When using this training device, after the user stands on the lower support base 11, the elbow support blocks 33 can provide guidance on the placement of the user's elbows, ensuring that the user can place their forearms in the correct position when placing their upper limbs for support, ensuring a comfortable posture during training, achieving effective support for the user from the upper limb support sections 31, and reducing the load when swinging the legs.

[0060] Furthermore, the elbow support block 33 is provided with an arc-shaped support groove 331. In the direction of arm extension, the elbow support block 33 has a corresponding arc-shaped support groove 331 to ensure the user's comfort when placing their arm.

[0061] Furthermore, the upper support plate 3 is equipped with a grip bar 34 that matches the upper limb support part 31. In addition to using the elbow support block 33 to position the user's arms, a grip bar 34 for the user to hold is also provided at the end of the elbow support block 33. When the user is performing leg swing training, after both hands are in place, they can hold the grip bar 34 to further ensure the stability of the upper body and ensure the safety of training.

[0062] Example 4 refer to Figure 5In a preferred embodiment of this utility model, an item placement area 35 is provided on the side of the upper support plate 3 near the U-shaped opening 32, and a stop block 351 is provided on the side of the item placement area 35 near the U-shaped opening 32. By separately opening a portion of the plate surface in the groove of the U-shaped opening 32 as the item placement area 35, and processing its upper surface with anti-slip patterns, users can place water bottles, towels, and other miscellaneous items needed during training in this area for convenient simultaneous use during training. At the same time, the stop block 351 located at the end can also block these items, preventing them from falling due to the inevitable vibration of the entire training device during training, thus improving the overall practicality.

[0063] Further, refer to Figure 6 The U-shaped opening 32 is equipped with a safety buckle 321. A safety rope or safety belt can be wrapped around the safety buckle 321 on both sides of the U-shaped opening 32 to secure the user's upper body after standing still, further ensuring the user's safety during leg swing training and preventing sudden situations such as exhaustion or slipping.

[0064] Further, refer to Figure 7 A folding bracket 38 is provided on the side of the upper support plate 3 away from the upper limb support part 31. By setting the folding bracket 38, the user can adjust it to extend it above the upper support plate 3 during training to hold mobile devices such as mobile phones and tablets, and use it during leg swing training to improve the user experience.

[0065] Example 5 refer to Figure 4In a preferred embodiment of this utility model, a stroke detection mechanism 4 is provided on the base 1, including a front detection rod 41 and a rear detection rod 42. The front detection rod 41 and the rear detection rod 42 are rotatably mounted on both sides of the vertical support 2, and their relative angle with the vertical support 2 is adjustable. A sensor 43 is provided on the top of each of the front detection rod 41 and the rear detection rod 42. By providing the front detection rod 41 and the rear detection rod 42 on at least one side of the base 1, the user can adjust the forward and backward stroke according to the required swing amplitude of their leg before performing leg-swinging training, and adaptively adjust the relative angle between the front detection rod 41 and the rear detection rod 42 and the vertical support 2, i.e., the supporting column 21. During leg-swinging training, when the user's affected leg swings to the position of the sensor 43 on the front detection rod 41 and the rear detection rod 42, the sensor 43 will feed the data back to the control system on the training device. In this embodiment of the utility model, a control panel 36 is provided on the upper support plate 3, which can communicate with the sensor 43 to receive feedback signals during training. When the user's leg swinging motion or range is not in place, the sensor 43 will send an abnormal signal to the control panel 36 and remind the user through the display screen using sound and light signals, so that the user consciously swings the leg to the preset position, thereby further ensuring the therapeutic training effect.

[0066] Furthermore, both the front detection rod 41 and the rear detection rod 42 are telescopic rods. Users can operate them on the control panel 36 by selecting a gear that matches their height and training level through a pre-programmed control program. This allows them to control and adjust the rotation position and telescopic length of the front detection rod 41 and the rear detection rod 42, ensuring that the sensor 43 can move to the required detection position and accurately detect and alert users to different leg swing strokes.

[0067] Furthermore, in a preferred embodiment of this utility model, two sets of stroke detection mechanisms 4 are provided and symmetrically arranged on both sides of the lower support 11. By providing one set of stroke detection mechanisms 4 on each side, the two sets of stroke detection mechanisms 4 can be used to detect the swinging motion of the left and right legs respectively. The sensor 43 is closer to the corresponding affected leg, ensuring detection sensitivity and accuracy.

[0068] Example 6 refer to Figure 5 and Figure 8In a preferred embodiment of this utility model, the lower support base 11 is provided with two lifting pedals 111, which are symmetrically arranged with respect to the center line of the lower support base 11. The two lifting pedals 111 correspond to the positions of the patient's left and right feet when standing. Before training, the user's standing position is marked to facilitate the user's positioning and maintain correct posture. After determining the affected leg to be trained, the lifting pedal 111 under the other supporting leg is raised a certain distance, allowing the affected leg to be trained to remain suspended in the air, facilitating swinging and reducing interference and friction with the lower support base 11, further improving training safety.

[0069] Furthermore, a control panel 36 and an emergency stop switch 37 are provided on the upper support plate 3, and the lifting pedal 111 is communicatively connected to the control panel 36. In this embodiment of the invention, the control panel 36 can integrate the control of the swinging and extension of the front detection rod 41 and the rear detection rod 42, the relative rotation of the upper support plate 3 and the lower support base 11, and the height adjustment of the vertical support 2. The height adjustment of the lifting pedal 111 can also be integrated into the control panel 36 for centralized control. In case of an unexpected situation during adjustment and training, the user can also promptly press the emergency stop switch 37 located next to the control panel 36 to reset the lifting pedal 111 in an emergency, ensuring that they can stand safely.

[0070] Example 7 Further, refer to Figure 4 and Figure 8 The lower support base 11 is provided with a receiving groove 112, and a rotating screw 113 is rotatably connected in the receiving groove 112. The base 1 is provided with a limiting groove 12 that matches the rotating screw 113. In use, after the lower support base 11 is rotated and adjusted to a horizontal position, the rotating screw 113 in the receiving groove 112 can be unscrewed and inserted into the limiting groove 12 on the corresponding end face of the base 1. The lower support base 11 is fixed by tightening the screw head at the end, ensuring the connection stability between the lower support base 11 and the base 1, avoiding relative shaking due to vibration during training, and further improving the stability of use.

[0071] Furthermore, a pulley 13 is provided on the side of the base 1 away from the lower support 11, and a gripping groove 39 is provided on the bottom side of the upper support plate 3 away from the upper limb support 31. When the training device is not in use and needs to be moved and stored, the upper support plate 3 and the lower support 11 can be rotated to a storage position where they are in contact with the vertical bracket 2. The user can then place both hands into the gripping groove 39 to hold the top of the entire training device, which will tilt the device. The pulley 13 under the base 1 will then contact the ground, allowing the entire training device to be pushed, making it easy to move to the desired location for setup and storage, further improving the overall practicality.
