DETAILED DESCRIPTION

[0016] The following is combined with Figure 1-3 This application is described in further detail.

[0017] The embodiment of the present application discloses a leg rehabilitation exercise device, including a base plate 1, a pressure seat 5 is arranged on the surface of the base plate 1, a connecting plate 18 is fixedly connected to the surface of the pressure seat 5, a fixing plate 8 is fixedly connected to the side of the base plate 1 surface away from the pressure seat 5, an elastic mechanism is arranged between the fixing plate 8 and the pressure seat 5, a through groove 17 adapted to the connecting plate 18 is arranged on the surface of the fixing plate 8, a plurality of groups of limiting mechanisms are arranged on the outer surface of the connecting plate 18, and the limiting mechanisms all include a groove 12 opened on the outer surface of the connecting plate 18, a wedge-shaped block 11 is slidably connected inside the groove 12, a first spring 6 is fixedly connected between the wedge-shaped block 11 and the inner surface of the groove 12, and the portion of the wedge-shaped block 11 located outside the groove 12 is a right triangle, and the inclined surface of the wedge-shaped block 11 faces the fixing plate 8, and a reset mechanism is arranged on the surface of the connecting plate 18, which can drive the wedge-shaped block 11 to move to the inside of the groove 12.

[0018] Furthermore, the elastic mechanism includes a guide rod 7 fixedly mounted on the surface of the pressure seat 5, the guide rod 7 passes through the fixed plate 8, a second spring 13 is sleeved on the surface of the guide rod 7, one end of the second spring 13 is fixedly connected to the pressure seat 5, and the other end of the second spring 13 is fixedly connected to the fixed plate 8.

[0019] Furthermore, the reset mechanism includes a convex plate 14 fixedly mounted on the surface of the wedge-shaped block 11, a reset plate 15 is provided on the surface of the connecting plate 18, the reset plate 15 abuts against the convex plate 14, and an electric push rod 16 is fixedly connected to the surface of the reset plate 15, the fixed end of the electric push rod 16 is fixedly connected to the connecting plate 18, and the extension direction of the electric push rod 16 is parallel to the groove 12.

[0020] In this embodiment, when the patient performs rehabilitation training for the legs, the patient can sit on the mat 3 on the surface of the base plate 1, with both feet against the pressure seat 5 and push the pressure seat 5 to move, so as to achieve leg strength training, activate and restore the function of damaged nerves, improve the strength and endurance of the leg muscles, and improve the range of motion of the joints. At this time, the second spring 13 located between the pressure seat 5 and the fixing plate 8 is compressed. When the legs move back, if the patient's legs suddenly lose force, the rebounding second spring 13 and the pressure seat 5 may easily injure the patient by mistake. By setting the connecting plate 18, the wedge-shaped block 11 and other mechanisms, when the feet push the pressure seat 5 to move, the connecting plate 18 also moves accordingly. Since the wedge-shaped block 11 is set to an inclined surface on the side facing the fixing plate 8, when the wedge-shaped block 11 passes through the through groove 17 of the fixing plate 8, the wedge-shaped block 11 is pushed into the groove 12, and the first spring 6 is compressed. When the wedge-shaped block 11 moves out of the through groove 17, the compressed first spring 6 is reset, thereby driving the wedge-shaped block 11 to move out of the groove 12, and the other side of the wedge-shaped block 11 is against the surface of the fixing plate 8, thereby limiting the reset of the pressure seat 5 and avoiding the situation where the pressure seat 5 accidentally injures the patient.

[0021] In this embodiment, by setting a reset mechanism, when the pressure seat 5 needs to be reset, first, ensure that the patient's feet return to the safe area, then drive the electric push rod 16 to move, and then drive the reset plate 15 to move, so that all the convex plates 14 can be pushed to move, and drive all the wedge-shaped blocks 11 to move into the groove 12, so that the connecting plate 18 can move smoothly in the through groove 17, so that the pressure seat 5 can be reset.

[0022] Furthermore, a slide seat 4 is provided on the surface of the base plate 1, and a first slide groove 9 and a second slide groove 10 are opened on the surface of the base plate 1. The two ends of the pressure seat 5 are slidably installed inside the first slide groove 9, and the two ends of the slide seat 4 are slidably installed inside the second slide groove 10. The first slide groove 9 is flush with the second slide groove 10 on one side close to the fixed plate 8, and the length of the second slide groove 10 is greater than the length of the first slide groove 9.

[0023] In this embodiment, the slide 4 is used to place the patient's feet. Since the lengths of the first slide groove 9 and the second slide groove 10 are different, when the slide 4 and the pressure seat 5 are located at the initial end, the slide 4 and the pressure seat 5 are not in contact. Therefore, when the slide 4 retreats to the initial end of the second slide groove 10, the pressure seat 5 is brought back to the initial end by the second spring 13, and the pressure seat 5 will not hit the slide 4.

[0024] Furthermore, a side of the surface of the bottom plate 1 away from the fixed plate 8 is fixedly connected to the back plate 2 , and a cushion 3 is fixedly connected to the surface of the back plate 2 and the bottom plate 1 .

[0025] In this embodiment, by arranging the cushion 3 on the bottom plate 1 and the back plate 2, the comfort level for the patient can be improved.
