SPECIFIC EMBODIMENT

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the embodiments of the utility model, and obviously, the described embodiments only are a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor all relate to the range of protection of the utility model.

[0025] Embodiment 1

[0026] As Figures 1-2As shown, this embodiment proposes a lower limb exercise device for neurorehabilitation, including a body 1. Rotating arms 2 are movably connected to both sides of the body 1 via rotating shafts. Pedals 3 are movably connected to the outside of both rotating arms 2 via rotating shafts. Wrapping straps 4 are fixedly connected to the top of both pedals 3. Fixed shells 5 are fixedly connected to both sides of the bottom of the body 1. Card plates 6 are embedded in both sides of the inside of both fixed shells 5. Elastic springs 7 are fixedly connected to both sides of the inside of both fixed shells 5. Sliding plates 8 are fixedly connected to the outer ends of the four elastic springs 7. Connecting cylinders 10 are fixedly connected inside the sliding plates 8. Rotating levers 11 are provided inside the connecting cylinders 10.

[0027] In this embodiment, a counterweight 9 is fixedly connected to one side of each of the four sliding plates 8. The sliding plates 8 are slidably connected to the fixed shell 5, which facilitates the fixing of the counterweight 9.

[0028] In this embodiment, the rotating lever 11 is in contact with the inside of the connecting cylinder 10. The cross-section of the rotating lever 11 is U-shaped, which facilitates the rotation and extension of the rotating lever 11.

[0029] In this embodiment, the rotating lever 11 extends to the gap between the card plate 6 and the fixed shell 5. Two card slots are provided on one side of the fixed shell 5, which can facilitate the rotating lever 11 to limit the sliding plate 8.

[0030] When using the device, to exercise the patient's lower limbs, the operator first needs to step into the wrapping strap 4, with the sole of the foot in contact with the pedal 3. The patient can then perform rehabilitative exercises by repeatedly stepping on the pedal and feeling the muscles working. To ensure the stability of the device, the operator can pull the rotating lever 11 outwards. After the rotating lever 11 leaves the slot, it can be reinserted into the connecting cylinder 10 and stored inside the sliding plate 8. At this time, the spring spring 7 will quickly stretch, causing the sliding plate 8 to move outwards. When the rotating lever 11 is fully inside the sliding plate 8, the sliding plate 8 can be smoothly ejected. Afterwards, the operator can pull the rotating lever 11 out again and insert it into the gap between the card plate 6 and the fixed shell 5, thus ensuring the limiting function of the sliding plate 8. This increases the contact area between the bottom of the device and the ground, ensuring the safety of the patient during use, and also making it easier to store the base.

[0031] Example 2

[0032] like Figures 3-4 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that both sides of the inner side of the body 1 are provided with placement slots 12, and both sides of the outer side of the body 1 are movably connected with movable doors 13 through rotating shafts, which can facilitate the rotation of the movable doors 13.

[0033] In the embodiment, the two movable doors 13 are fixedly connected with handles 14 on the outer sides, and sliding grooves 15 are formed on the outer sides of the two wrapping belts 4, so that the handles 14 can drive the movable doors 13 to rotate.

[0034] In the embodiment, sliding blocks 16 are slidably connected in the two sliding grooves 15, and limiting rods 17 are fixedly connected to the outer sides of the two sliding blocks 16, so that the sliding blocks 16 can slide.

[0035] In the embodiment, a plurality of counterweight strips 18 are slidably connected in the two wrapping belts 4, and the plurality of counterweight strips 18 are in contact with one side of the limiting rods 17, so that the counterweight strips 18 can perform counterweight work.

[0036] In use, when the patient needs to perform weight training in a long-term exercise process, the staff needs to pull the handle 14 outward, and the handle 14 drives the movable door 13 to rotate synchronously in the process of pulling, the movable door 13 moves away from the outside of the machine body 1 in the process of moving, then the counterweight strip 18 stored in the placing groove 12 is inserted into the pedal 3, the sliding block 16 is moved upward, the sliding block 16 drives the limiting rod 17 to move synchronously in the process of moving, then the limiting rod 17 is loosened when the counterweight strip 18 is completely inserted into the pedal 3, at this time, the sliding block 16 and the limiting rod 17 fall back to limit the counterweight strip 18, so that the patient can be trained to increase the weight, and the rehabilitation speed is increased.

[0037] The above is only a preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
