DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0017] Example 1

[0018] See also Figure 1-3 The support rod 11 is fixed on the support rod 7 and the support rod 12 is fixed on the support rod 7. The support rod 11 is fixed on the support rod 7 and the support rod 12 is fixed on the support rod 7.

[0019] Example 2

[0020] In this embodiment, Figure 1-3As shown, the top surface of the base 1 is respectively provided with a first slide groove 3 and a second slide groove 4, and are respectively provided on both sides of the movable groove 6. The first slide groove 3 and the second slide groove 4 are respectively slidably connected with the first slider 15 and the second slider 17, and are respectively threadedly sleeved on the first screw rod 14 and the second screw rod 16 rod wall. The side walls on both sides of the movable groove 6 are provided with a strip hole 18, and are respectively connected to the interior of the first slide groove 3 and the second slide groove 4. The side walls of the first slider 15 and the second slider 17 are fixedly installed with a push block 19. The first slider 15 and the second slider 17 are respectively slidably connected to the interior of the strip hole 18, and the top of the push block 19 is higher than the first slider 15 and the second slider 17. The top surface, and the side walls are fitted with the side walls on both sides of the movable groove 6. The first slide groove 3 and the second slide groove 4 are respectively rotatably connected with the first screw rod 14 and the second screw rod 16. The first slider 15 and the second slider 17 are respectively threadedly sleeved on the rod walls of the first screw rod 14 and the second screw rod 16. The left end side wall of the base 1 is symmetrically fixed with a reciprocating motor 5. The output shaft of the reciprocating motor 5 is fixedly connected with the left ends of the first screw rod 14 and the second screw rod 16 respectively through the inside of the side wall of the base 1. When the patient's knee joint is rehabilitated, the two reciprocating motors 5 are respectively controlled to move the first slider 15 and the second slider 17 on both sides, and move the position of the movable seat 9 back and forth respectively.

[0021] It should be noted that, in this embodiment, when using the knee joint rehabilitation device, Figure 1-3 As shown, when the patient's knee joint is being rehabilitated, the patient sits on the base 1, places the sole of the foot on the placement plate 10, and fixes the sole of the foot with the Velcro 11. First, the leg is moved by the device, and the reciprocating motor 5 is turned on respectively, so that the first slider 15 and the second slider 17 on both sides clamp the movable seat 9, and then move synchronously. At this time, the first screw rod 14 and the second screw rod 16 have the same rotation direction, which is convenient for moving the position of the movable seat 9 back and forth. When the device treatment is completed, the patient uses the power of his legs to move the movable seat 9 to a certain position. The first slider 15 and the second slider 7 move in opposite directions under the action of the reciprocating motor 5, and move to the ends of the first slide groove 3 and the second slide groove 4 respectively. The patient's legs are extended and retracted, driving the movable seat 9 to move, so that the movable seat 9 is against the side wall of the baffle 12 (the width of the baffle 12 is less than the distance between the push plates 19 on both sides to prevent the push block 19 from being blocked by the baffle 12 when moving). Under the action of the tensioning spring 13, the patient's legs can be easily reset and the patient's knee joint can be protected.
