[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a portable hand gripping rehabilitation training device, comprising an anti-detachment ring 1, a fixing plate 2 fixedly connected to the upper left side of the anti-detachment ring 1, an electric push rod 18 fixedly connected inside the fixing plate 2, a sliding plate 3 fixedly connected to the drive end of the electric push rod 18, a sliding plate 3 slidably connected to the lower part of the sliding plate 3 inside the fixing plate 2, a connecting plate 4 rotatably connected to the left end of the sliding plate 3, a plurality of fixing rods 7 fixedly connected to the lower part of the connecting plate 4, a first spring 17 fixedly connected to the top of the inner wall of the fixing rod 7, a sliding rod 14 fixedly connected to the lower end of the first spring 17, and a sliding rod 14 slidably connected to the outer wall of the sliding rod 14. The inner wall of the fixed rod 7, the lower end of the sliding rod 14 is fixedly connected to a first pull ring 15, the lower end of the first pull ring 15 is movably connected to a second pull ring 16, the lower part of the second pull ring 16 is fixedly connected to a fixed ring 8, the lower part of the fixed ring 8 is fixedly connected to a finger sleeve 6, the upper right side of the finger sleeve 6 is fixedly connected to a fixed clip 9, the inner right end of the fixed clip 9 is fixedly connected to a rack 13, the outer side of the rack 13 is meshed with a gear 12, the middle part of the gear 12 is fixedly connected to a rotating rod 11, the upper end of the rotating rod 11 is fixedly connected to a swivel buckle 10, the rotating rod 11 is rotatably connected to the middle part of the fixed ring 8, and the lower part of the finger sleeve 6 is fixedly connected to a rubber base 5.
[0026] Specifically, the anti-dislodgement ring 1 is fixed to the patient's arm. The sliding plate 3 is adjusted by the electric push rod 18. The sliding plate 3 drives the connecting plate 4 to move left and right, thereby moving the finger sleeve 6 to a position suitable for the patient's fingers. The patient inserts their fingers into the finger sleeve 6, which is made of rubber. The rotating buckle 10 rotates the rotating rod 11 and the gear 12. The rotation of the gear 12 drives the rack 13 to move. The movement of the rack 13 drives the fixing clip 9 to rotate into the fixing ring 8, thereby fastening the finger sleeve 6 and making it suitable for the patient's finger size. When the patient exerts force to grasp, the finger sleeve 6 drives the second pull ring 16 to move. The second pull ring 16 drives the first pull ring 15 to move. The first pull ring 15 drives the sliding rod 14 to slide within the fixing rod 7. At this time, the first spring 17 inside the fixing rod 7 and the sliding rod 14 is pulled apart. When the patient releases their fingers, the first spring 17 tightens, thereby allowing the patient to perform grasping rehabilitation training.
[0027] Reference Figure 4 and Figure 6The lower left end of the anti-slip ring 1 is fixedly connected to a fixing ear 20, and the lower right end of the anti-slip ring 1 is fixedly connected to a buckle 19. The buckle 19 can be inserted into the fixing ear 20 to fix the anti-slip ring 1 to the patient's arm. The left end of the sliding plate 3 is rotatably connected to a rotating shaft 25. A second spring 28 is installed on the outer wall of the rotating shaft 25. A retaining ring 27 is fixedly connected to the end of the second spring 28. A snap fastener 26 is fixedly connected to the opposite side of the retaining ring 27. The retaining ring 27 and the snap fastener 26 are slidably connected to the outer wall of the rotating shaft 25. The left end of the sliding plate 3 and the right end of the connecting plate 4 are provided with a slot 29. The position of the slot 29 corresponds to the position of the retaining ring 27.
[0028] Specifically, after the anti-dislodgement ring 1 is fixed, the snap button 26 can be pressed. The snap button 26 drives the retaining ring 27 to move inward. At this time, the connecting plate 4 can rotate to adjust the angle so that the finger sleeve 6 can fit the fingers with different bends. After adjusting the angle, the snap button 26 is released. At this time, the retaining ring 27 slides to the retaining groove 29 set at the right end of the connecting plate 4 under the action of the second spring 28, so that the connecting plate 4 and the sliding plate 3 no longer rotate, thereby fixing the finger sleeve at the angle suitable for the patient.
[0029] Reference Figure 5 An electric heating device 21 is installed inside the rubber base 5. An electric wire 23 is fixedly connected to the left end of the electric heating device 21. The outer wall of the electric wire 23 passes through the outer wall of the rubber base 5. A cover plate 24 is fixedly connected to the bottom of the rubber base 5. A heat dissipation hole 22 is opened on the upper part of the rubber base 5.
[0030] Specifically, when the temperature is low, the power supply can be connected via the wire 23 to heat the electric heating device 21 inside the rubber base 5. The heat emitted by the electric heating device 21 is transmitted to the patient's hand through the heat dissipation holes 22 on the upper part of the rubber base 5, accelerating blood circulation in the patient's hand and enabling the patient to perform better grasping training.
[0031] Working principle: The anti-dislodgement ring 1 is fixed to the patient's arm by the buckle 19. The electric push rod 18 is adjusted to move the sliding plate 3 to a suitable position. The snap button 26 on the left end of the sliding plate 3 is pressed to adjust the angle between the connecting plate 4 and the sliding plate 3 so that the finger sleeve 6 is adjusted to a suitable angle for the patient's fingers. The snap button 26 is released, and the retaining ring 27 is locked in the slot 29 of the sliding plate 3 and the connecting plate 4, so that the sliding plate 3 and the connecting plate 4 can no longer rotate. Then, the finger sleeve 6 is put on the patient's fingers, and the buckle 10 is rotated so that all the finger sleeves 6 can fit tightly on the patient's fingers. At this time, the patient can perform grasping training. When the patient's hand temperature is low, the blood flow in the hand will slow down, which will affect the patient's rehabilitation training. At this time, the electric heating device 21 in the rubber base 5 can be activated. The heat emitted by the electric heating device 21 is transferred to the patient's hand through the heat dissipation hole 22 to keep the temperature of the patient's hand constant, so that the patient can perform grasping rehabilitation training better.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
