Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 10As shown, a wrist and back training device with adjustable training intensity for medical rehabilitation includes a support base 1. The top of the support base 1 has a first mounting groove 2 and a second mounting groove 3. A sliding assembly 4 is disposed inside the first mounting groove 2. The sliding assembly 4 includes two guide rods 41, which are fixedly connected between the front and rear side walls of the first mounting groove 2. A fixing assembly 42 is slidably connected to the outer surfaces of the two guide rods 41. The fixing assembly 42 includes two sliding blocks 421, which are slidably connected to the outer surfaces of the two guide rods 41 respectively. A support block 422 is fixedly connected to the top of the two sliding blocks 421. An arc-shaped plate 4 is fixedly connected to the center of the top of the support block 422. 23. Two symmetrically distributed fixing blocks 424 are fixedly connected to one side of the outer surface of the arc plate 423. A strap 425 is fixedly connected to the top of the fixing block 424. Two symmetrically distributed locking components 426 are fixedly connected to the other side of the outer surface of the arc plate 423. The locking component 426 includes a fixing block 4261. The fixing block 4261 is fixedly connected to the outer surface of the arc plate 423, and the inner cavity of the fixing block 4261 matches the strap 425. A pull rod 4264 is slidably connected inside the fixing block 4261. A protective shell 4262 is fixedly connected to the outer surface of the pull rod 4264. A return spring 4263 is fixedly connected between the inner cavity of the protective shell 4262 and the fixing block 4261.

[0031] At the start of training, place the arm inside the curved plate 423, then pull the strap 425 around the arm and through the slot in the fixing block 4261. Next, pull the lever 4264 outward. Then, adjust the position of the holes on the surface of the strap 425 according to the size of the arm. When it is adjusted to the appropriate position, release the lever 4264. At this time, the lever 4264 will spring back under the action of the return spring 4263, thereby fixing the strap 425.

[0032] Two symmetrically distributed buffer springs are fixedly connected between the rear side wall of the support block 422 and the rear side wall of the mounting groove 2, so that the fixing component 42 can return to its original position better after training.

[0033] like Figure 9 As shown, a fixing component 2 5 is fixedly connected to the top of the support base 1. The fixing component 2 5 includes two support plates 51. The bottom of the two support plates 51 is fixedly connected to the top of the support base 1. A rotating plate 52 is rotatably connected between the two support plates 51. Two symmetrically distributed rotating supports 53 are fixedly connected to the front bottom of the rotating plate 52. A movable rod 54 is rotatably connected between the inner surfaces of the rotating plate 52. A hook 55 is rotatably connected to the bottom of the movable rod 54.

[0034] The top of the rotating plate 52 is equipped with five medical Velcro straps to facilitate the fixation of the patient's five fingers. Then, the movable rod 54 is moved according to the patient's recovery level, and the hook 55 is slightly rotated so that it can hook the sling ring 633 for easy subsequent stretching operations.

[0035] like Figure 6 , Figure 7 and Figure 8 As shown, a tensioning assembly 6 is provided inside the mounting groove 2 3. The tensioning assembly 6 includes a reciprocating screw 61, which is rotatably connected between the front and rear side walls of the mounting groove 2 3. A smooth rod 2 62 is fixedly connected between the front and rear side walls of the mounting groove 2 3. A transmission assembly 63 is slidably connected to the outer surfaces of the reciprocating screw 61 and the smooth rod 2 62. The transmission assembly 63 includes two sliding blocks 2 631, which are slidably connected to the outer surfaces of the reciprocating screw 61 and the smooth rod 2 62, respectively. A rubber plate 632 is slidably connected between the two sliding blocks 2 631. The rubber plate 632 has a groove inside. The support base 1 has several evenly distributed lifting rings 633 fixedly connected. The support base 1 has an installation groove 64 inside. The reciprocating screw 61 passes through the installation groove 64 and is rotatably connected to the front side wall of the installation groove 64. The outer surface of the reciprocating screw 61 is fixedly connected to a bevel gear 65. The outer surface of the bevel gear 65 is meshed with a bevel gear 66. The inner surface of the bevel gear 66 is fixedly connected to a rotating shaft 67. The outer surface of the rotating shaft 67 is provided with a ratchet and pawl mechanism 68. One end of the rotating shaft 67 passes through one end of the support base 1 and extends into the outside and is fixedly connected to a knob 7. The left end of the support base 1 is rotatably connected to a knob 7.

[0036] When adjustments are needed based on the patient's recovery level, simply turn knob 7. Knob 7 will drive rotating shaft 67 to rotate, which in turn drives bevel gear 2 66 to rotate. As bevel gear 2 66 rotates, it will further drive bevel gear 1 65 to rotate, which in turn drives reciprocating screw 61 to rotate, and then drives transmission assembly 63 to move.

[0037] The ratchet and pawl mechanism 68 used in this solution is a conventional design in the prior art. It mainly consists of a ratchet, a pawl, a fixed post, and a return spring. The ratchet is fixedly connected to the outer surface of the rotating shaft 67, the pawl is rotatably connected to the left side wall of the mounting groove 3 64, the left end of the fixed post is fixedly connected to the left side wall of the mounting groove 3 64, and the return spring is fixedly connected between the pawl and the fixed post.

[0038] In addition, the rubber plate 632 is also a conventional design in the existing technology. It is mainly made of rubber with different elastic coefficients spliced ​​together. Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force. It can return to its original shape after the external force is removed. Different training standards can be set. For example, stretching to a certain height will complete the training purpose. According to the different recovery levels of the patients, the hook 55 can be hooked onto the corresponding ring 633 to adjust the training intensity.

[0039] The rubber plate 632 is slidably connected via the slide rail on the sliding block 631. The sliding connection makes it easy to replace the rubber plate 632, and the rubber plate 632 will not detach during training after being limited and fixed by the two sliding blocks 631.

[0040] The working principle of this utility model is as follows: At the start of training, place the arm inside the arc-shaped plate 423, then pull the strap 425 around the arm and through the slot of the fixing block 4261. Next, pull the lever 4264 outward. Then, adjust the position of the holes on the surface of the strap 425 according to the size of the arm. When the position is adjusted to a suitable position, release the lever 4264. At this time, the lever 4264 rebounds under the action of the return spring 4263, thereby fixing the strap 425. Then, place the hand on the top of the rotating plate 52 and tie it with the Velcro strap. Then, move the movable rod 54 and... The hook 55 hooks onto the corresponding ring 633, and then the wrist is lifted upwards to pull the rubber plate 632 via the movable rod 54, thus performing the exercise. Depending on the degree of rehabilitation, the knob 7 can be turned, which will drive the rotating shaft 67 to rotate, and then drive the second bevel gear 66 to rotate. As the second bevel gear 66 rotates, it will further drive the first bevel gear 65 to rotate, which in turn drives the reciprocating screw 61 to rotate, so that the rubber block corresponding to the rubber plate 632 moves below the rotating plate 52, making it easier for the hook 55 to hook onto the ring 633, thereby adjusting the training intensity.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
