DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Please refer to Figures 1-4, the present utility model provides the following technical solutions: It includes a support frame 1, and two support cross plates 2 are slidably connected to the inner wall of the support frame 1. Elastic straps 21 are slidably connected to the inner walls of the two support cross plates 2. One end of each of the two elastic straps 21 is fixedly connected to a limiting rod 211. The bottom end of the elastic strap 21 is rotatably connected to a U-shaped rod 22. A grip 23 is rotatably connected to the inner wall of the U-shaped rod 22. Folding assemblies 3 are arranged at the bottom ends of the two support cross plates 2. The folding assembly 3 includes an upper fixed rod 31 and an L-shaped lower folding rod 32. The upper fixed rod 31 is slidably connected to the bottom of the corresponding support cross plate 2. The L-shaped lower folding rod 32 is hinged to the bottom end of the corresponding upper fixed rod 31. Limiting sliders 33 are fixedly connected to the top ends of the two upper fixed rods 31. Limiting chutes 24 are opened at the bottom ends of the support cross plates 2. The limiting sliders 33 are slidably connected to the inner walls of the corresponding limiting chutes 24. One end of the elastic strap 21 is fixedly connected to one side of the limiting slider 33. A shoe plate 4 is arranged at one end of the L-shaped lower folding rod 32. A shoe cover 41 is fixedly connected to one side of the shoe plate 4. A connecting pipe 42 is fixedly connected to the top end of the shoe plate 4. A connecting rod 321 is arranged at one end of the L-shaped lower folding rod 32. The connecting pipe 42 is rotatably connected to the side wall of the connecting rod 321.

[0018] In this implementation: The support frame 1 supports each component of the device. The support frame 1 is placed on the bed, facilitating limb training for patients in bed and being convenient for hemiplegic patients and bedridden patients to use. The two support crossbars 2 slide horizontally in the sliding tracks inside the support frame 1. The support crossbars 2 support the elastic pull belt 21. The support crossbars 2 are supported and slide-guided through the limit sliding grooves 24. The limit slider 33 supports the upper fixed rod 31. The upper fixed rod 31 supports the corresponding L-shaped downward folding rod 32. The L-shaped downward folding rod 32 supports the shoe plate 4. One side of the shoe plate 4 contacts the patient's sole. The shoe plate 4 is connected to the patient's foot through the shoe cover 41. The shoe cover 41 realizes the expansion and contraction of the opening through a zipper design, thereby enabling the installation and disassembly of the patient's foot and the shoe cover 41, facilitating the locking of the shoe plate 4 and the patient's foot. The elastic pull belt 21 is limited by the limit rod 211 to prevent the elastic pull belt 21 from contracting into the support crossbar 2. The limit rod 211 supports the U-shaped rod 22. The U-shaped rod 22 supports the grip 23. The patient pulls the U-shaped rod 22 by holding the grip 23. The U-shaped rod 22 pulls the limit rod 211. The limit rod 211 pulls the elastic pull belt 21, enabling the elastic pull belt 21 to extend. The grip 23 and the U-shaped rod 22 descend. And the rotational connection relationship between the U-shaped rod 22 and the limit rod 211 enables the U-shaped rod 22 and the grip 23 to be changed at multiple angles to adapt to different training requirements. When the patient pulls down the grip 23 with the hand, the grip 23 extends the elastic pull belt 21 downward from the support crossbar 2 through the U-shaped rod 22 and the limit rod 211, and the elastic pull belt 21 is stretched and extended. The elastic force of the elastic pull belt 21 causes resistance when the patient pulls, achieving the exercise effect on the upper limb. When the elastic pull belt 21 is pulled, the other end pulls the limit slider 33. The limit slider 33 slides inside the limit sliding groove 24 in the direction of the elastic pull belt 21. The limit slider 33 drives the upper fixed rod 31 to slide. The upper fixed rod 31 drives the L-shaped downward folding rod 32 to slide. When the L-shaped downward folding rod 32 slides, it pulls the shoe plate 4 to tilt towards the grip 23 through the connecting rod 321 and the connecting pipe 423, enabling the shoe plate 4 to drive the patient's foot to perform ankle pump training through the shoe cover 41. And the limit sliding groove 24 limits the sliding stroke of the limit slider 33, preventing components such as the limit slider 33 from driving the shoe plate 4 to travel too far, so that the shoe plate 4 does not tilt too much when driving the foot to perform ankle pump training, which affects the comfort of the patient's foot. Through the use of this device, synchronous training of the upper limb driving the lower limb during training is realized, and the operation is simple and practical, suitable for use in bed, improving the training efficiency.

[0019] The inner wall of the support frame 1 is rotatably connected to a lead screw 11. One end of the lead screw 11 is fixedly connected to a turntable 12. The lead screw 11 is threadedly connected to the inner walls of two support cross plates 2. The driving directions of the lead screw 11 for the two support cross plates 2 are opposite. The threads on the side wall of the lead screw 11 are divided into two groups, and the opening directions of the two groups of threads are opposite, so that when the lead screw 11 rotates, it can drive the two support cross plates 2 to complete synchronous and reverse sliding. The lead screw 11 supports the turntable 12. The turntable 12 is outside the support frame 1. By controlling the rotation of the turntable 12, the turntable 12 drives the lead screw 11 to rotate, and the lead screw 11 drives the two support cross plates 2 to slide, so that the two support cross plates 2 can approach or move away from each other, so that the two grips 23 and the two shoe plates 4 can be adjusted to different positions for the patient to use and adapt to different training needs.

[0020] A spring 25 is fixedly connected to the inner wall of the limit chute 24. The spring 25 is above the corresponding elastic tension belt 21. The spring 25 is fixedly connected to one side of the corresponding limit slider 33. The spring 25 pushes the limit slider 33. The forces exerted by the spring 25 and the elastic tension belt 21 on the limit slider 33 are in opposite directions. So that after the elastic tension belt 21 pulls the limit slider 33, the spring 25 can push the limit slider 33 back, which helps the patient's foot to complete the ankle pump training.

[0021] A torsion spring is provided between the upper fixed rod 31 and the L-shaped lower folding rod 32. The torsion spring drives the corresponding L-shaped lower folding rod 32 to flip upward. Rotation blocking rods 311 are rotatably connected to one side of each of the two upper fixed rods 31. The rotation blocking rods 311 are slidably connected to one side of the corresponding L-shaped lower folding rods 32. A damping layer is provided between the rotation blocking rods 311 and the corresponding upper fixed rods 31. The torsion spring makes the L-shaped lower folding rod 32 flip upward and fold, which helps the storage of the device in the non-use state. After the L-shaped lower folding rod 32 flips downward and docks with the upper fixed rod 31, by controlling the rotation of the rotation blocking rod 311, the rotation blocking rod 311 can be rotated to one side of the L-shaped lower folding rod 32, so that the rotation blocking rod 311 can limit the L-shaped lower folding rod 32 to prevent the L-shaped lower folding rod 32 from folding upward, and the damping between the rotation blocking rod 311 and the upper fixed rod 31 can increase the stability of the rotation blocking rod 311 limiting the L-shaped lower folding rod 32.

[0022] A number of massage bumps 231 are fixedly connected to the side walls of both grips 23, and a number of massage ridges 43 are fixedly connected to one side of each of the two shoe plates 4; when a patient holds the grips 23 with their hands, the grips 23 massage the patient's hands through the number of massage bumps 231, and the shoe plates 4 massage the patient's feet through the number of massage ridges 43. There are many acupoints on the hands and feet, and massaging these acupoints can promote the balance inside the body, help eliminate fatigue and promote health, and can enhance the immune system function, help release the tension in the body, promote physical and mental relaxation, and improve the overall health status.

[0023] The working principle and usage process of the present utility model: When the device is in use, place the device on the patient's bed, then rotate the L-shaped downward folding rod 32 downward. The L-shaped downward folding rod 32 drives components such as the shoe plate 4 to flip downward. Then rotate the rotation blocking rod 311 to lock and limit the L-shaped downward folding rod 32. Open the zipper on the shoe cover 41 and stretch the patient's foot into the interior of the shoe cover 41, and then zip up to complete the locking. The patient pulls the U-shaped rod 22 by holding the grip 23. The U-shaped rod 22 pulls the limit rod 211, and the limit rod 211 pulls the elastic pull belt 21. When the elastic pull belt 21 is pulled, the other end pulls the limit slider 33. The limit slider 33 slides in the limit chute 24 towards the direction of the elastic pull belt 21. The limit slider 33 drives the upper fixing rod 31 to slide, and the upper fixing rod 31 drives the L-shaped downward folding rod 32 to slide. When the L-shaped downward folding rod 32 slides, it pulls the shoe plate 4 to tilt towards the grip 23. Then the spring 25 can push the limit slider 33 to return, so that the shoe plate 4 can drive the patient's foot to perform ankle pump training through the shoe cover 41. The massage bumps 231 and the massage ridges 43 massage the patient's hands and feet, promote the balance inside the body, help eliminate fatigue and promote health, and can enhance the immune system function.
