[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0038] The following will further describe the present application in detail Figure 1-9 with reference to the attached drawings.

[0039] An embodiment of the present application discloses a portable training device for adult upper limb rehabilitation therapy. Referring to Figure 1-9 , a portable training device for adult upper limb rehabilitation therapy includes a back hanging part 1. On one side of the back hanging part 1, a fixed seat 2 for providing a fixed track is installed. Above the fixed seat 2, a rotating handle 3 for stretching is installed.

[0040] The fixed seat 2 includes a fixed rod 21. Above the fixed rod 21, a sliding rail 23 is provided. Inside the sliding rail 23, a moving seat 24 is slidably connected. At the bottom of the moving seat 24, a silent ball bearing is embedded. At the upper end of the moving seat 24, a through hole 241 is provided. At the upper end of the moving seat 24, a mounting column 242 is fixedly connected. Below the fixed rod 21, a hook 26 is installed. On the side of the moving seat 24, a magnetic grating displacement sensor (optional) can be installed to connect to a mobile phone APP to record the joint range of motion in real time.

[0041] The rotating handle 3 includes a connecting pipe 31. Below the connecting pipe 31, a mounting hole 32 is provided. Inside the mounting hole 32, the mounting column 242 is inserted. At both ends of the connecting pipe 31, connecting rods 33 are inserted. At both ends of the connecting rods 33, grips 34 are fixedly connected. Below the connecting rods 33 and outside the connecting pipe 31, a T-shaped hook 36 is rotatably connected. Above the hook 26, an elastic band 4 is sleeved. One end of the elastic band 4 passes through the through hole 241 and then is divided into two ends and sleeved outside the two T-shaped hooks 36, bifurcating into a Y shape. The bifurcating length can be finely adjusted by a "day" shaped buckle to ensure the symmetry of the resistance of both arms.

[0042] The back hanging part 1 is carried on the user's body to support the fixed seat 2. The sliding rail 23 on the fixed seat 2 restricts the sliding track of the rotating handle 3, ensuring that when the user drives the rotating handle 3 to move, the moving track of the rotating handle 3 is the same and there is no error in the training action. During the carrying process, the back hanging part 1 is separated from the fixed seat 2, and the rotating handle 3 and the fixed seat 2 are parallel to each other, which is convenient for the user to carry the fixed seat 2 and the rotating handle 3.

[0043] During training, the mounting post 242 is separated from the mounting hole 32, rotated, and then reinserted into the mounting hole 32, thereby ensuring that the rotating handle 3 is separated from the fixing base 2. The two ends of the rotating handle 3 are also located on both sides of the body, which is convenient for the user to grasp the grip 34 with both hands. At the same time, one end of the elastic band 4 is divided into two ends to pull the T-hook 36, thereby tightening the connecting rod 33 close to both sides of the connecting tube 31 to prevent the connecting rod 33 from being separated from the connecting tube 31. When the user pulls the grip 34 to move, the elastic band 4 is also stretched and deformed. By pulling the rotating handle 3 to overcome the deformation elastic force of the elastic band 4 and moving back and forth, the user's elbow flexion function is trained.

[0044] In this embodiment, refer to Figure 1 and Figure 2 Specifically, one side of the back hanging 1 is fixedly connected to a slot 11, and one end of a fixing rod 21 is fixedly connected to an insert plate 22, which can be inserted into the slot 11. Inserting the insert plate 22 into the slot 11 connects the fixing base 2 to the back hanging 1, making it convenient and quick to assemble the fixing base 2 and the back hanging 1. The inside of the slot 11 is a dovetail-shaped slide rail, ensuring zero wobble after the insert plate 22 is inserted.

[0045] In this embodiment, refer to Figure 3 Specifically, a slot is provided at one end of the fixed rod 21, and a roller 25 is rotatably connected inside the slot. The elastic band 4 passes around the roller 25 and then passes through the through-hole 241. The roller 25 reduces the friction between the elastic band 4 and the fixed rod 21, thereby improving the service life of the elastic band 4.

[0046] In this embodiment, refer to Figure 4 Specifically, a plurality of adjustment holes 27 are provided below the fixed rod 21. The opening at one end of the adjustment hole 27 is smaller than the opening at the other end, with the smaller end being closer to the end of the fixed rod 21. One end of the hook 26 is inserted into the adjustment hole 27 and moves within the adjustment hole 27. The upper end of the hook 26 is inserted from the end with the larger diameter of the adjustment hole 27. When the hook 26 is moved to the end with the smaller diameter of the adjustment hole 27, the hook 26 cannot be separated from the adjustment hole 27 in the vertical direction. By aligning the open side of the hook 26 with the end with the larger diameter of the adjustment hole 27, when the elastic band 4 pulls the hook 26 toward the end with the smaller diameter of the adjustment hole 27, the hook 26 becomes even more difficult to separate from the fixed rod 21.

[0047] In this embodiment, refer to Figure 5 Specifically, a plurality of anti-slip bars 35 are fixedly connected to the outside of the handle 34. The anti-slip bars 35 increase the force between the user's hand and the handle 34, so that the user can hold it more firmly and more steadily.

[0048] In this embodiment, refer to Figure 5 and Figure 6Specifically: one end of the connecting rod 33 is located inside the connecting tube 31 and has a slot 331, which fits into the outer side of the mounting post 242. A locking plate 38 is rotatably connected to the connecting rod 33 on the outer side of the connecting tube 31. A bayonet is provided on the upper end of the T-shaped hook 36, and one end of the locking plate 38 is snapped into the bayonet. A push block 37 is fixedly connected to the outer side of the T-shaped hook 36 on one side of the connecting tube 31, and one end of the push block 37 protrudes outward. When the user rotates the pushing block 37, the protruding end of the pushing block 37 rotates toward the connecting tube 31, thereby increasing the distance between the T-hook 36 and the two ends of the connecting tube 31, and the notch 331 moves inside the connecting tube 31 away from the mounting post 242, and the notch 331 can rotate inside the connecting tube 31. When exercising the elbow, the connecting rod 33 cannot rotate, thereby ensuring stability and standard during the movement. The T-hook 36 is locked by the locking plate 38 to ensure that the T-hook 36 does not continue to rotate, thereby ensuring a constant distance between the T-hook 36 and the connecting tube 31. The user rotates the handle 34 in different directions with both hands, and the handle 34 drives the connecting rod 33 and the T-hook 36 to rotate. The T-hook 36 drives one end of the elastic band 4 to move in different directions. The elastic band 4 is stretched and wound around the outside of the connecting tube 31, and the user overcomes the elastic force of the elastic band 4 to perform wrist rotation training.

[0049] In this embodiment, refer to Figure 6 Specifically, a viewing port is provided on the connecting tube 31 above the mounting hole 32. This allows the user to directly verify that the mounting post 242 is properly inserted into the mounting hole 32. This prevents poor training results or device damage caused by incorrect installation. The viewing port also allows the user to directly verify that the notch 331 is in contact with the mounting post 242, ensuring that the connecting rod 33 remains easily visible when it is positioned away from the mounting post 242.

[0050] In this embodiment, refer to Figure 1 and Figure 2 Specifically, the back rig 1 includes front and rear armor plates connected by elastic straps. The armor plates are constructed from a lightweight aviation aluminum frame and 3D breathable mesh. The front and rear armor plates are connected by multiple detachable elastic straps. Both the chest and shoulder straps can be quickly adjusted with Velcro, making it easy for the user to don the back rig 1.

[0051] In this embodiment, refer to Figure 3 and Figure 6 Specifically, the movable base 24 can only slide back and forth within the sliding rail 23. The cross-sections of the mounting post 242 and the mounting hole 32 are both polygonal and match each other. The inner cavity of 32 is milled flat to form a polygonal anti-rotation surface. This ensures that when the mounting post 242 is inserted into the mounting hole 32, the rotating handle 3 and the movable base 24 cannot rotate. The movable base 24 cannot rotate within the sliding rail 23 either, ensuring that the rotating handle 3 remains fixed along the trajectory of the fixed base 2 as it moves back and forth.

[0052] In this embodiment, refer to Figure 7 Specifically, the lower end of the T-shaped hook 36 is located above the fixed rod 21. When the T-shaped hook 36 rotates with the rotating handle 3, the T-shaped hook 36 rotates without contacting the fixed rod 21 and will not be blocked by the fixed rod 21.

[0053] Working Principle: To use, unfold the elastic webbing and put it on like a vest, centering the front carapace over the sternum. Tighten the shoulder straps and chest straps until the carapace stops shaking. Wear the backpack 1 on your back. Grab the lifting handle 34 and pull it upward, raising the rotating handle 3 as a whole. Separating the mounting hole 32 from the mounting post 242, the user rotates the rotating handle 3 so that it is perpendicular to the fixing base 2. Reinsert the mounting post 242 into the mounting hole 32 and insert the hook 26 into different adjustment holes 27 to adjust the tension of the elastic band 4 and change the load required by the user to pull the rotating handle 3. The handle 34 can rotate 360° around the connecting tube 31 to accommodate different gripping positions.

[0054] After preparation is completed, the user pulls the grip 34 to move the rotating handle 3 closer to the back hanging 1. The rotating handle 3 moves through the T-hook 36 and the movable seat 24 to stretch the elastic band 4. The elastic band 4 increases the load on the user pulling the rotating handle 3. When the user pulls the rotating handle 3, the elbow is bent to train and restore the elbow flexion function of the upper limb.

[0055] When pulling the handle 34, avoid excessive force or rapid pulling to avoid muscle strain or joint injury. Keep your movements smooth and even, and avoid sudden impact. During training, keep your body upright and avoid hunching or twisting your body. Correct posture can ensure the training effect while reducing compensatory movements in other parts of the body and avoiding unnecessary injuries. Gradually increase the resistance of the elastic band 4 according to the user's recovery progress and strength level. Start with a lower resistance level in the early stages and gradually adjust to a higher resistance level as your strength increases.

[0056] After completing elbow flexion training, the user can use the same device to train wrist rotation. At this point, the device is already installed and does not need to be readjusted.

[0057] The user separates the locking plate 38 from the T-hook 36 and rotates the T-hook 36, causing the pushing block 37 on the T-hook 36 to rotate close to the two ends of the connecting tube 31. The protruding end of the pushing block 37 approaches the connecting tube 31 and pushes the connecting rod 33 away from the connecting tube 31. The notch 331 at one end of the connecting rod 33 is separated from the mounting post 242, so that the connecting rod 33 can rotate inside the connecting tube 31. The user rotates the handle 34 in different directions with both hands to simulate the daily action of twisting a towel. The handle 34 drives the connecting rod 33 and the T-hook 36 to rotate in different directions. When the T-hook 36 rotates, the elastic band 4 is stretched and wrapped around the outside of the connecting tube 31, thereby increasing the load on the user and exercising the wrist rotation function.

[0058] During the rotation of the handle 34, the user's wrist rotates clockwise and counterclockwise. This repetitive movement increases the range of motion of the wrist joint, helping to restore joint flexibility and function. Through continuous training, the user's wrist mobility can be gradually improved, allowing the user to better perform various daily movements.

[0059] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
