DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figures 1 to 3 In embodiment 1 of the present invention, a structural diagram of a hand rehabilitation training device for rehabilitation medicine provided by an embodiment of the present invention is provided, comprising: a device mounting base 1, an exercise component rotatably mounted on the device mounting base 1, the exercise component comprising a mounting shaft 4 rotatably mounted on the device mounting base 1 and a bending rod 3 fixedly mounted on both sides of the mounting shaft 4, the bending rods 3 on both sides being installed at opposite angles, and a finger exercise component 2 being rotatably mounted on both sides of the bending rod 3; a driving mechanism arranged inside the device mounting base 1 for driving the mounting shaft 4 to rotate, the driving mechanism comprising a second transmission shaft 8 and a second transmission shaft 8 rotatably mounted on the device mounting base 1. A first transmission shaft 6 is arranged on the mounting seat 1, and the first transmission shaft 6 is transmission-connected with the mounting shaft 4; a transmission protection structure is provided between the second transmission shaft 8 and the first transmission shaft 6, and the second transmission shaft 8 provides power for the rotation of the first transmission shaft 6; the transmission protection structure includes a mounting rod 10 and a resistance rotating rod 11, the mounting rod 10 is fixedly mounted on the second transmission shaft 8, the first end of the resistance rotating rod 11 is rotationally mounted on the mounting rod 10, the second end of the resistance rotating rod 11 is in contact with the first transmission shaft 6, and the middle position of the resistance rotating rod 11 is attracted to the second transmission shaft 8 through an attraction component.

[0030] When exercise is needed, the present invention fixes both hands on the finger exercise component 2, and then drives the installation shaft 4 through the driving mechanism to drive the finger exercise component 2 to rotate, so as to automatically perform recovery exercise on the patient's arm; if the device mounting seat 1 is not set in the right position, or because the patient's position is inaccurate, to avoid arm injury to the patient, when the patient's arm can no longer be stretched, the installation shaft 4 cannot rotate under the action of the first transmission shaft 6 and the second transmission shaft 8 under the patient's resistance. Therefore, at this time, the resistance rod 11 overcomes the suction force of the suction component, causing the resistance rod 11 to deflect, so that the resistance rod 11 and the first transmission shaft 6 are out of contact, so that the second transmission shaft 8 can no longer provide power to the first transmission shaft 6, thereby avoiding excessive stretching of the patient's arm and protecting the patient well.

[0031] Specifically, the interference rotating rod 11 can be rotatably mounted on the mounting rod 10 through a bearing. The mounting rod 10 can be fixedly mounted on the second transmission shaft 8. The mounting rods 10 can be arranged in a circular array on the end surface of the second transmission shaft 8. Example

[0032] See also Figures 1 to 7 The main difference between Example 2 and Example 1 is that, in order for the first transmission shaft 6 to drive the installation shaft 4 to rotate, a first gear 5 is fixedly sleeved on the outer side of the installation shaft 4. The first gear 5 meshes with a second gear 7 fixedly sleeved on the first transmission shaft 6. Thus, when the first transmission shaft 6 rotates, the installation shaft 4 is driven to rotate via the second gear 7 and the first gear 5. In order to further drive the second transmission shaft 8 to rotate, a drive motor 9 is also fixedly mounted on the device mounting base 1. The drive motor 9 is in transmission connection with the second transmission shaft 8. The second transmission shaft 8 can be in transmission connection with the drive motor 9 via a gear assembly, a coupling assembly, or a belt assembly, thereby providing power for the transmission of the second transmission shaft 8. The drive motor 9 can be connected to an external power supply, and a battery can also be provided on the device mounting base 1 to power the drive motor 9.

[0033] The bending rod 3 may be a Z-shaped structure.

[0034] like Figure 2 and 3As shown, as a preferred embodiment of the present invention, in order to achieve the attraction of the middle position of the interference rotating rod 11 on the second transmission shaft 8, a first adsorption member 17 is fixedly installed in the middle of the interference rotating rod 11, and the first adsorption member 17 is attracted to the second adsorption member 18, and the second adsorption member 18 is fixedly installed on the second transmission shaft 8. The first adsorption member 17 and the second adsorption member 18 can be magnets. In this way, when a jam occurs, the interference rotating rod 11 can overcome the attraction force between the first adsorption member 17 and the second adsorption member 18, so that the interference rotating rod 11 deflects, and the interference rotating rod 11 and the first transmission shaft 6 are temporarily disengaged and released, temporarily ending the transmission. There is no less than one interference rotating rod 11. The interference rotating rod 11 can be installed on the mounting rod 10 through a rotating shaft. In order to enable the interference rotating rod 11 to return to the transmission position after deflection, the interference rotating rod 11 can be rotatably installed on the mounting rod 10 through a torsion spring.

[0035] like Figure 2 and 3 As shown, as a preferred embodiment of the present invention, in order to protect the stretched patient arm, at least one matching arc-shaped rack 13 is provided on the outer side of the first transmission shaft 6, and a matching driving arc-shaped rack 12 is provided at the end of the interference rotating rod 11. The driving arc-shaped rack 12 is fixedly mounted on the interference rotating rod 11. There can be more than two matching arc-shaped racks 13. If there are multiple matching arc-shaped racks 13, they can be arranged in a circular array on the first transmission shaft 6. Specifically, when the arm is overstretched, the interference rotating rod 11 overcomes the suction resistance, and the interference rotating rod 11 drives the driving arc-shaped rack 12 to deflect. The driving arc-shaped rack 12 drives the first transmission shaft 6 to rotate in the opposite direction at the moment of deflection. In this way, the first transmission shaft 6 can drive the mounting rotating shaft 4 to rotate in the opposite direction, thereby reducing the stretching degree of the patient's arm and providing a certain degree of protection for the patient's arm.

[0036] like Figure 4 As shown in FIG. 1 , as a preferred embodiment of the present invention, the finger exercise component 2 includes a base 19 and a retaining ring 37 for securing the patient's hand. The base 19 is rotatably mounted on the bending rod 3. This allows the patient's hand to be secured to the base 19, thereby automatically exercising the patient's arm and hand.

[0037] like Figure 4 As shown, as a preferred embodiment of the present invention, in order to exercise the fingers, a plurality of stretching components 20 for exercising the fingers are provided on the base 19. The number of the stretching components 20 can be 5.

[0038] like Figure 4 and 5As shown, as a preferred embodiment of the present invention, the stretching assembly 20 includes a pull ring 21, a cylinder 22 and a fixed shaft 23. The fixed shaft 23 is fixedly mounted on the base 19, and the cylinder 22 is slidably sleeved on the fixed shaft 23. The fixed shaft 23 and the cylinder 22 are elastically connected. The pull ring 21 is fixedly mounted on the cylinder 22. In this way, the patient places his fingers in the pull ring 21 and then pulls the cylinder 22 to exercise his fingers.

[0039] like Figure 4 and 5 As shown, to achieve damping adjustment during exercise, the fixed shaft 23 and cylinder body 22 enclose a sealed chamber filled with damping fluid. A damping adjustment mechanism is provided between the fixed shaft 23 and cylinder body 22. The fixed shaft 23 and cylinder body 22 are connected by a first elastic member 24. This damping adjustment mechanism enables automatic damping adjustment to meet user needs. The first elastic member 24 can be a coil spring.

[0040] like Figure 5 、 6As shown in Figure 7, the damping adjustment mechanism includes a plurality of intermittent disks 31 axially arranged along the fixed shaft 23, and the plurality of intermittent disks 31 rotate on the fixed shaft 23. A plurality of slide grooves 32 are arranged in an array on the outer side of the intermittent disk 31. A connecting disk 34 is fixedly installed on the intermittent disk 31, and the connecting disk 34 is affixed to the mating disk 33. The mating disk 33 is fixedly installed on the fixed shaft 23. The plurality of connecting disks 34 cooperate with the plurality of mating disks 33 to divide the sealing cavity into a plurality of independent intervals; a second through hole 36 is provided on the connecting disk 34, and a first through hole 35 is provided on the mating disk 33. The first through hole 35 is used to cooperate with the second through hole 36 to connect two adjacent independent intervals. A driving rod 29 for sliding into the slide groove 32 is also provided on the inner wall of the cylinder body 22, and the driving rod 29 is set to rotate in one direction. Specifically, when the cylinder 22 is activated by the pull ring 21, it slides along the fixed axis 23. During this sliding process, the rotating rod 29 is driven to pass through one of the slots 32 on the intermittent discs 31, thereby driving the intermittent disc 31 to rotate. The rotation of the intermittent disc 31 drives the connecting disc 34 to rotate. The rotation of the connecting disc 34 causes the overlap between the second through hole 36 and the first through hole 35 to change, changing the resistance of the damping fluid to flow between the independent intervals and changing the damping. When the finger stops, the cylinder 22 is then activated by the first elastic member 24 to return to its initial position. At this time, due to the unidirectional rotation of the driving rotating rod 29, the rotating rod 29 is deflected when passing through the slot 32 during the recovery process, preventing the intermittent disc 31 from rotating. The finger then pulls the pull ring 21 again, repeating the above action. The intermittent disc 31 rotates to the next position, thus achieving gradual adjustment of the damping. In this way, the damping is periodically increased or decreased, that is, periodically loaded or unloaded, to meet the needs of exercise. The slot 32 can be spiral.

[0041] In order to realize the unidirectional rotation of the driving rod 29, the driving rod 29 is rotatably installed inside the cylinder body 22 through a torsion spring, and a limit pin 30 is also provided on the cylinder body 22. The limit pin 30 abuts against the driving rod 29, so that the driving rod 29 can only rotate downward and cannot rotate upward.

[0042] like Figure 6As shown, as a preferred embodiment of the present invention, in order to meet the patient's need for fixed damping, an inner ring 25 is slidingly provided inside the cylinder body 22, and the driving rod 29 is rotatably mounted on the inner ring 25. The inner ring 25 is fixedly mounted on the mounting plate 26 via no less than two sliding rods. The mounting plate 26 is arranged on the outside of the cylinder body 22 and is positionally adjustable. In this way, when it is necessary to fix the damping, it is only necessary to adjust the distance between the mounting plate 26 and the cylinder body 22 so that the driving rod 29 is away from the intermittent plate 31 at the corresponding position. When the cylinder body 22 slides, the driving rod 29 cannot contact the slide groove 32, so that the damping cannot be changed, meeting the training requirement of constant damping.

[0043] In order to adjust the position between the mounting plate 26 and the cylinder body 22 , a position adjustment mechanism is provided between the mounting plate 26 and the cylinder body 22 .

[0044] like Figure 6 As shown in FIG. 1 , as a preferred embodiment of the present invention, the position adjustment mechanism includes a threaded sleeve 27 that is rotatably mounted on the outside of the mounting plate 26. The threaded sleeve 27 is rotatably mounted on a threaded ring 28, and the threaded ring 28 is fixedly mounted on the cylinder body 22. Thus, when the distance between the cylinder body 22 and the mounting plate 26 needs to be adjusted, the threaded sleeve 27 is rotated, and the mounting plate 26 is moved closer to or away from the cylinder body 22 under the action of the threaded ring 28, thereby adjusting the distance between the mounting plate 26 and the cylinder body 22.

[0045] The position adjustment mechanism can also be configured as a telescopic cylinder, with both ends of the telescopic cylinder fixedly mounted on the mounting plate 26 and the cylinder body 22 respectively.

[0046] The bottom of the device mounting base 1 can also be mounted with a movable base, thereby enabling the present invention to be moved. This facilitates adjustment of the position of the device mounting base 1 to meet the rehabilitation needs of patients with different arm lengths. The base includes a support rod fixedly mounted on the bottom of the device mounting base 1 and universal wheels mounted on the support rod, each of which has a locking structure.

[0047] One end of the limiting ring 37 is fixedly mounted on the base 19, and the other end is movably arranged. The other end of the limiting ring 37 can be mounted on the base 19 by snap fastening or Velcro. The two ends of the first elastic member 24 are respectively fixed on the fixed shaft 23 and the cylinder body 22.

[0048] The working principle of the present invention is:

[0049] Specifically, when a hospital patient needs to exercise his arms and fingers, the present invention is pushed to the front of the bed, and then the patient's two hands are fixed on the base 19 by the limiting ring 37. If the patient only exercises his arms, only the fingers can be exercised without the stretching component 20, or the fingers can be exercised through the stretching component 20 while exercising the arms; the driving motor 9 is energized to drive the second transmission shaft 8 to rotate, and the second transmission shaft 8 drives the first transmission shaft 6 to rotate by the interference rotating rod 11, the driving arc rack 12 and the matching arc rack 13, etc. The first transmission shaft 6 drives the installation shaft 4 to rotate through the second gear 7 and the first gear 5, and the installation shaft 4 drives the finger exercise components 2 on both sides to rotate to exercise the arms. If the device mounting seat 1 is not set in the right position, or due to In order to prevent the patient's arm from being injured due to the inaccurate position of the patient, when the patient's arm can no longer be stretched, the installed rotating shaft 4 cannot be rotated under the action of the first transmission shaft 6 and the second transmission shaft 8 under the patient's resistance. Therefore, the conflicting rotating rod 11 overcomes the suction force of the first adsorption member 17 and the second adsorption member 18, causing the conflicting rotating rod 11 to deflect, so that the conflicting rotating rod 11 and the first transmission shaft 6 are disengaged, so that the second transmission shaft 8 cannot provide power to the first transmission shaft 6, avoiding excessive stretching of the patient's arm and protecting the patient well; the conflicting rotating rod 11 drives the driving arc rack 12 to deflect, and the driving arc rack 12 drives the first transmission shaft 6 to reverse at the moment of deflection. Rotate, so that the first transmission shaft 6 can drive the mounting shaft 4 to rotate in the opposite direction, reduce the stretching degree of the patient's arm, and provide a certain degree of protection for the patient's arm; when the finger is inserted into the pull ring 21, the finger exercise is performed, when the cylinder 22 is acted upon by the pull ring 21, the cylinder 22 slides along the fixed axis 23, and during the sliding process, the rotating rod 29 is driven to pass through one of the 32 on the intermittent disk 31, thereby driving the intermittent disk 31 to rotate, and the rotation of the intermittent disk 31 drives the connecting disk 34 to rotate, and the rotation of the connecting disk 34 drives the overlapping position between the second through hole 36 and the first through hole 35 to change, thereby changing the resistance of the damping fluid between the independent intervals, changing the damping, and when the finger rests, then under the action of the first elastic member 24, the cylinder 22 returns to its initial position. Position, at this time, due to the unidirectional rotation setting of the driving rotating rod 29, when the driving rotating rod 29 passes through the slide groove 32 during the recovery process, it is deflected, so that the intermittent disk 31 does not rotate; then the finger pulls the pull ring 21 again, and the above action is repeated again, so that the intermittent disk 31 turns to the next position, thereby realizing gradual adjustment of the damping, and thus periodically increasing or reducing the damping, that is, periodically loading or unloading, to meet the exercise needs; when the damping needs to be fixed, it is only necessary to adjust the distance between the mounting plate 26 and the cylinder body 22, so that the driving rotating rod 29 is away from the intermittent disk 31 at the corresponding position, and the driving rotating rod 29 cannot contact the slide groove 32 during the sliding process of the cylinder body 22, so that the damping cannot be changed, thereby meeting the training requirements of constant damping.
