[0002] Currently, there are many upper limb lifting training devices used in the medical rehabilitation market. Traditional upper limb lifting training devices are relatively complex in structure and are suitable for upper limb lifting training for healthy people, but their use for upper limb rehabilitation lifting exercises and training for rehabilitation patients and people with disabilities is limited.

[0003] For example, publication number CN208611690U discloses a rehabilitation training device. This device includes a support frame, a counterweight support tube, an adjustable support, a counter, a track, counterweights, a central handle, double side handles, and a sliding part, wherein the counterweights can be placed on the counterweight support tube or on the support tube above the sliding part. The beneficial effects of this utility model are: 1. This upper limb pressing trainer is easy to use and has a long service life; the counter allows for convenient observation of training time and repetitions. 2. It is equipped with an adjustable support and counterweights of different weights to obtain the desired angle and weight. 3. It is suitable for the training needs of different trainees or the same trainee at different recovery stages.

[0004] The aforementioned patent requires operating the handle's top screw when adjusting the support angle. Since patients undergoing upper limb rehabilitation training often cannot operate their upper limbs normally or can only operate with one hand, this causes inconvenience for patients when adjusting the training support angle. Utility Model Content

[0005] Therefore, this utility model provides an upper limb rehabilitation training support mechanism, which solves the problem that patients often cannot operate their upper limbs normally or operate with one hand during upper limb rehabilitation training by means of adjustable support components, causing inconvenience for patients when adjusting the training support angle.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an upper limb rehabilitation training support mechanism, including a lifting training fixation frame. The top of the lifting training fixation frame is provided with an adjustable support component and a training support component. The adjustable support component includes a base, which is fixedly mounted on the top of the lifting training fixation frame. A rotating shaft is inserted inside the base, and a movable seat is fixedly sleeved on the outside of the rotating shaft. Two fixed sleeves are fixedly mounted on one side of the movable seat, and guide rods are inserted inside each of the two fixed sleeves. A connecting frame is fixedly connected to the top of the guide rods. A threaded rod is provided on the top of the movable seat, and a rotating wheel is fixedly sleeved on the outside of the threaded rod. A threaded sleeve is also sleeved on the outside of the threaded rod.

[0007] Preferably, the training support assembly includes a base two, which is fixedly mounted on the top of the press training frame. A rotating shaft two is inserted inside the base two, and a movable seat two is fixedly sleeved on the outside of the rotating shaft two. Two press trainer guide rods are fixedly mounted on one side of the movable seat two, and a connecting seat is fixedly mounted on the top of the two press trainer guide rods. A connecting shaft is fixedly inserted inside the connecting seat, and a press trainer body is sleeved on the outside of the two press trainer guide rods.

[0008] Preferably, the rotating shaft passes through one of the two side walls of the base and is connected to the two side walls of the base via bearings.

[0009] Preferably, one end of the guide rod extends into the interior of the fixed sleeve and is slidably connected to the fixed sleeve.

[0010] Preferably, one end of the threaded rod is connected to one side of the movable seat via a bearing, the other end of the threaded rod extends into the threaded sleeve and is connected to the threaded sleeve via a thread, and one end of the threaded sleeve is fixedly connected to the connecting frame.

[0011] Preferably, the second rotating shaft passes through both side walls of the second base and is connected to both side walls of the second base via bearings.

[0012] Preferably, the connecting shaft passes through the connecting frame and is connected to the connecting frame via a bearing.

[0013] The present invention has the following advantages:

[0014] 1. The lifting training frame, adjustable support component, and training support component form a triangular structure. The lifting training frame, adjustable support component, and training support component are connected by pivot one, pivot two, and connecting shaft, respectively. Thus, when it is necessary to change the angle between the training support component and the lifting training frame, it is only necessary to change the overall length of the adjustable support component to change the angle between the training support component and the lifting training frame.

[0015] 2. By rubbing the rotating wheel with the sole of the foot, the rotation of the wheel drives the threaded rod to rotate, which in turn drives the threaded sleeve to move along the threaded rod. The movement of the threaded sleeve drives the connecting frame to move, causing the longitudinal position of the connecting frame to change. When the connecting frame moves, it drives the connecting seat to move longitudinally through the connecting shaft, thereby changing the angle between the training support component and the lifting training fixation frame. No manual operation is required, making it convenient for patients undergoing upper limb rehabilitation training. Attached Figure Description

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See attached document Figure 1 -Appendix Figure 4The present invention provides an upper limb rehabilitation training support mechanism, including a lifting training frame 1. The top of the lifting training frame 1 is provided with an adjustable support component 2 and a training support component 3. The adjustable support component 2 includes a base 21, which is fixedly mounted on the top of the lifting training frame 1. A rotating shaft 22 is inserted inside the base 21. A movable seat 23 is fixedly mounted on the outside of the rotating shaft 22. Two fixed sleeves 24 are fixedly mounted on one side of the movable seat 23. Guide rods 25 are inserted inside the two fixed sleeves 24. A connecting frame 26 is fixedly connected to the top of the guide rods 25. A threaded rod 28 is provided on the top of the movable seat 23. A rotating wheel 27 is fixedly mounted on the outside of the threaded rod 28. A threaded sleeve 29 is mounted on the outside of the threaded rod 28.

[0025] In this implementation scheme, in order to achieve the goal of adjusting the angle of the training support without the patient having to use their hands, when it is necessary to adjust the angle of the training support component 3, the rotating wheel 27 is rotated by rubbing the sole of the foot. The rotation of the wheel 27 drives the threaded rod 28 to rotate, which in turn drives the threaded sleeve 29 to move along the threaded rod 28. The movement of the threaded sleeve 29 drives the connecting frame 26 to move, causing the longitudinal position of the connecting frame 26 to change. When the connecting frame 26 moves, it drives the connecting seat 35 to move longitudinally through the connecting shaft 36, thereby changing the angle between the training support component 3 and the lifting training fixation frame 1. This eliminates the need for manual operation and facilitates operation for patients undergoing upper limb rehabilitation training.

[0026] To achieve the goal of enabling the training support component 3 to move synchronously with the connecting frame 26, the device employs the following technical solution: The training support component 3 includes a base 31, which is fixedly mounted on the top of the lifting training frame 1. A rotating shaft 32 is inserted inside the base 31, and a movable seat 33 is fixedly fitted outside the rotating shaft 32. Two lifting trainer guide rods 34 are fixedly mounted on one side of the movable seat 33, and a connecting seat 35 is fixedly mounted on the top of the two lifting trainer guide rods 34. A connecting shaft 36 is fixedly inserted inside the connecting seat 35, and the lifting trainer body 4 is fitted outside the two lifting trainer guide rods 34. The rotating shaft 32 passes through... The connecting shaft 36 passes through the two side walls of the base 2 31 and is connected to the two side walls of the base 2 31 via bearings. The connecting shaft 36 passes through the connecting frame 26 and is connected to the connecting frame 26 via bearings. The lifting training fixed frame 1, adjustable support component 2, and training support component 3 form a triangular structure. The connection points of the lifting training fixed frame 1, adjustable support component 2, and training support component 3 are movably connected via rotating shaft 1 22, rotating shaft 2 32, and connecting shaft 36, respectively. Thus, when it is necessary to change the angle between the training support component 3 and the lifting training fixed frame 1, it is only necessary to change the overall length of the adjustable support component 2 to change the angle between the training support component 3 and the lifting training fixed frame 1.

[0027] To achieve the goal of adjusting the overall length of the adjustable support assembly 2, the device employs the following technical solution: A rotating shaft 22 passes through both side walls of the base 21 and is connected to both side walls of the base 21 via bearings; one end of a guide rod 25 extends into the fixed sleeve 24 and is slidably connected to the fixed sleeve 24; one end of a threaded rod 28 is connected to one side of the movable seat 23 via a bearing; the other end of the threaded rod 28 extends into the threaded sleeve 29 and is threadedly connected to the threaded sleeve 29; one end of the threaded sleeve 29 is fixedly connected to the connecting frame 26; by rubbing the rotating wheel 27 with the sole of the foot, the rotating wheel 27 rotates, causing the threaded rod 28 to rotate, which in turn causes the threaded sleeve 29 to move along the threaded rod 28 via the thread; the movement of the threaded sleeve 29 causes the connecting frame 26 to move, thus changing the longitudinal position of the connecting frame 26, thereby changing the overall length of the adjustable support assembly 2, and consequently changing the angle between the subsequent training support assembly 3 and the lifting training fixed frame 1.

[0028] The usage process of this utility model is as follows: When using this utility model, the lifting training frame 1, the adjustable support component 2, and the training support component 3 form a triangular structure. The joints of the lifting training frame 1, the adjustable support component 2, and the training support component 3 are movably connected by a rotating shaft 22, a rotating shaft 32, and a connecting shaft 36, respectively. Therefore, when it is necessary to change the angle between the training support component 3 and the lifting training frame 1, it is only necessary to change the overall length of the adjustable support component 2 to change the angle between the training support component 3 and the lifting training frame 1. When the angle is met, the rotating wheel 27 is rotated by rubbing the sole of the foot. The rotation of the rotating wheel 27 drives the threaded rod 28 to rotate, which in turn drives the threaded sleeve 29 to move along the threaded rod 28. The movement of the threaded sleeve 29 drives the connecting frame 26 to move, causing the longitudinal position of the connecting frame 26 to change. When the connecting frame 26 moves, it drives the connecting seat 35 to move longitudinally through the connecting shaft 36, thereby changing the angle between the training support component 3 and the lifting training fixed frame 1. When performing upper limb rehabilitation training, the patient pushes the lifting training device body 4 to slide along the lifting training device guide rod 34 to perform rehabilitation training.

[0029] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
