Description

Technical Field

[0001] This utility model relates to the field of upper limb rehabilitation training equipment technology, and in particular to a novel multifunctional upper limb rehabilitation training equipment. Background Technology

[0002] Upper limb rehabilitation trainers are devices used by patients to perform rehabilitation training on their upper limbs. When some elderly patients in wheelchairs use outdoor upper limb rehabilitation trainers for upper limb rehabilitation training, the training pulling mechanism of the trainer is fixed in height and cannot be adjusted, resulting in poor flexibility during use. When the training pulling mechanism of the trainer is set too high, it is not convenient for elderly people in wheelchairs with short arms to achieve the best training effect in upper limb rehabilitation training. Therefore, in order to address the above problems, a new type of multifunctional upper limb rehabilitation trainer is proposed. Utility Model Content

[0003] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A novel multifunctional upper limb rehabilitation training device includes a support column, a slider slidably connected to the inner top of the support column, a support shaft fixedly connected to the outer side of the slider, a bracket rotatably connected to one end of the outer side of the support shaft, pull rods rotatably connected to both ends of the bracket via pivots, a pulling frame fixedly connected to the bottom end of the pull rods, a connecting rope fixedly connected to the top of the slider, a guide shaft rotatably connected to the support column being contacted at the outer top of the connecting rope, a reel fixedly connected to the other end of the connecting rope, and a fixed shaft rotatably connected to the support column being fixedly connected to the center of the inner side of the reel.

[0006] As a further improvement of this utility model, a ball bearing is rotatably connected to the inner edge of the slider, and the ball bearing contacts the support column.

[0007] As a further improvement of this utility model, a worm gear is fixedly connected to the outer rear end of the fixed shaft, and a worm that penetrates the support column is meshed with the outer side of the worm gear, and the worm is rotatably connected to the support column.

[0008] As a further improvement of this utility model, a piston block is slidably connected to the inner side of the pulling frame, and an air pipe is connected to one end of the outer side of the pulling frame, with the other end of the air pipe connected to the support.

[0009] As a further improvement of this utility model, a piston plate is slidably connected to the inner side of the bracket, a push rod is fixedly connected to one end of the outer side of the piston plate, a resistance block is slidably connected to the outer side of the push rod and is slidably connected to the bracket, and the resistance block is in close contact with the support shaft. A spring is fixedly connected to the inner side of the resistance block, and the other end of the spring is fixedly connected to the push rod.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. A novel multifunctional upper limb rehabilitation training device, comprising a worm gear, a reel, a connecting rope, a slider, and a pull rod, is designed for use by elderly people in wheelchairs with short arms for upper limb rehabilitation training. First, the worm gear is rotated to engage the worm wheel, which in turn drives the reel to rotate via a fixed shaft. This causes the connecting rope to emerge from the outside of the reel. Under the weight of the support shaft, bracket, pull rod, and pulling frame, the slider lowers these components. Once the pulling frame is lowered to a height convenient for the elderly person to perform upper limb rehabilitation training, the worm gear is stopped, and the pulling frame is then pulled to perform the rehabilitation training. By rotating the worm gear to lower the pulling frame to a height convenient for the elderly person to perform rehabilitation training, the device ensures optimal training results for elderly people in wheelchairs with short arms, making it more flexible and convenient to use.

[0012] 2. A novel multifunctional upper limb rehabilitation training device, comprising a piston block, an air tube, a piston plate, and a resistance block, allows elderly people in wheelchairs to perform upper limb rehabilitation training by pressing the piston block and sliding it against the pull frame. This further forces gas from the pull frame into the support through the air tube. At this time, the piston plate compresses the spring via a push rod, thereby continuously increasing the tightness of the contact between the resistance block and the support shaft. By allowing the upper limb rehabilitation trainee to independently press the piston block to continuously increase the tightness of the contact between the resistance block and the support shaft, the friction between the resistance block and the support shaft can be continuously increased according to needs. This allows for a continuous increase in the difficulty of upper limb rehabilitation training when the pull frame is pulled, causing the support and support shaft to rotate, while the resistance block and support shaft continuously slide, thus improving the upper limb rehabilitation training effect for the trainee.

[0020] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1-5 As shown, a novel multifunctional upper limb rehabilitation training device includes a support column 1. A slider 2 is slidably connected to the top inner side of the support column 1. A support shaft 3 is fixedly connected to the outer side of the slider 2. A bracket 4 is rotatably connected to one end of the outer side of the support shaft 3. A pull rod 5 is rotatably connected to both the front and rear ends of the bracket 4 via a rotating shaft. A pulling frame 6 is fixedly connected to the bottom end of the pull rod 5. A connecting rope 8 is fixedly connected to the top of the slider 2. The top outer side of the connecting rope 8 contacts a guide shaft 9 that is rotatably connected to the support column 1. A reel 10 is fixedly connected to the other end of the connecting rope 8. A fixed shaft 11 that is rotatably connected to the support column 1 is fixedly connected to the center inner side of the reel 10.

[0023] Example 2

[0024] like Figure 3 As shown, in order to solve the problem of poor effect of slider 2 driving support shaft 3, bracket 4, pull rod 5 and pulling frame 6 to move downward, a ball bearing 7 is rotatably connected to the inner edge of slider 2, and the ball bearing 7 contacts support column 1. By making slider 2 contact support column 1 through ball bearing 7, the friction between slider 2 and support column 1 is reduced, so that slider 2 drives support shaft 3, bracket 4, pull rod 5 and pulling frame 6 to move downward better.

[0025] Example 3

[0026] like Figure 1-4 As shown, in order to solve the problem that the slider 2 cannot be stably positioned at the designated location after driving the support shaft 3, bracket 4, pull rod 5 and pulling frame 6 downward, a worm gear 12 is fixedly connected to the outer rear end of the fixed shaft 11. A worm 13 that penetrates the support column 1 is meshed with the outer side of the worm gear 12, and the worm 13 is rotatably connected to the support column 1. By rotating the worm 13 to mesh with the worm gear 12, the slider 2 is controlled to drive the support shaft 3, bracket 4, pull rod 5 and pulling frame 6 to move. The self-locking characteristic of the worm gear 12 meshing with the worm 13 ensures that the slider 2 can be stably positioned at the designated location after driving the support shaft 3, bracket 4, pull rod 5 and pulling frame 6 downward.

[0027] Example 4

[0028] like Figure 1 and Figure 5 As shown, in order to solve the problem that it is inconvenient for upper limb rehabilitation trainees to control the piston plate 16 to push the resistance block 18 through the push block 17, the inner side of the pulling frame 6 is slidably connected to the piston block 14, and one end of the outer side of the pulling frame 6 is connected to the air pipe 15, and the other end of the air pipe 15 is connected to the support 4. By pressing the piston block 14 to slide with the pulling frame 6, the gas in the pulling frame 6 is further pressed into the support 4 through the air pipe 15, which makes it easier for upper limb rehabilitation trainees to control the piston plate 16 to push the resistance block 18 through the push block 17.

[0029] Example 5

[0030] like Figure 5As shown, to address the issue of difficulty in increasing the training difficulty for upper limb rehabilitation trainees as needed, a piston plate 16 is slidably connected to the inner side of the support 4. A push rod 17 is fixedly connected to one end of the outer side of the piston plate 16. A resistance block 18, which is slidably connected to the support 4, is slidably connected to the outer side of the push rod 17. The resistance block 18 is in close contact with the support shaft 3. A spring 19 is fixedly connected to the inner side of the resistance block 18, and the other end of the spring 19 is fixedly connected to the push rod 17. By compressing the spring 19 through the push block 17, the resistance block 18 is further brought into close contact with the support shaft 3, thereby increasing the friction between the resistance block 18 and the support shaft 3. When the support 4 is controlled to cause the resistance block 18 to slide against the support shaft 3, it is convenient to increase the training difficulty for upper limb rehabilitation trainees as needed.

[0031] In this embodiment, when using the device for upper limb rehabilitation training for elderly people in wheelchairs with short arms, the worm gear 13 is first rotated to engage the worm wheel 12, which further drives the winding wheel 10 to rotate via the fixed shaft 11. At this time, the connecting rope 8 will continuously rotate out from the outside of the winding wheel 10 under the guidance of the guide shaft 9. Then, under the gravity of the support shaft 3, bracket 4, pull rod 5, and pulling frame 6, the slider 2 will drive the support shaft 3, bracket 4, pull rod 5, and pulling frame 6 to move downwards. When the pulling frame 6 moves to a height that is convenient for the elderly to perform upper limb rehabilitation training, the rotation of the worm gear 13 is stopped. Then, the pulling frames 6 on both sides are pulled back and forth with both hands to rotate the pull rod 5 and the bracket 4, and to rotate the bracket 4 and the support shaft 3 to perform rehabilitation training. During upper limb rehabilitation training, by pressing the piston block 14 and sliding the pull frame 6, the gas in the pull frame 6 is further forced into the support 4 through the air tube 15. At this time, the piston plate 16 will compress the spring 19 through the push rod 17, thereby continuously increasing the tightness of the contact between the resistance block 18 and the support shaft 3. By continuously increasing the tightness of the contact between the resistance block 18 and the support shaft 3, the friction between the resistance block 18 and the support shaft 3 is continuously increased according to the needs. Thus, when the pull frame 6 is pulled to make the support 4 and the support shaft 3 rotate, and the resistance block 18 and the support shaft 3 slide continuously to perform upper limb rehabilitation training, the difficulty of upper limb rehabilitation training is continuously increased autonomously, thereby making the upper limb rehabilitation training effect of the upper limb rehabilitation trainees better.
