DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0025] Please refer to Figure 1-Figure 8。The lower limb rehabilitation exercise device includes: a bed board 1, at the bottom of which four legs distributed in a matrix are fixedly installed, and a plurality of movable openings 2 are provided on the bed board 1. Two side plates 3 are fixedly installed at the bottom of the bed board 1. A plurality of concave plates 4 are arranged between the two side plates 3. The two sides of the concave plate 4 are respectively in contact with the two side plates 3. A roller 5 is rotatably installed in each of the plurality of concave plates 4. The top of the roller 5 protrudes above the top of the concave plate 4, so as to ensure that the roller 5 can contact the patient's limb. And the plurality of rollers 5 are respectively adapted to the plurality of movable openings 2, and the roller 5 can pass through the movable opening 2. A C-shaped frame 6 is fixedly installed at the bottom of the bed board 1, in which a vertical screw rod 7 is rotatably installed, and a motor is fixedly installed at the bottom of the C-shaped frame 6, and the output shaft of the motor is fixedly connected to the bottom end of the vertical screw rod 7. A lifting plate 8 is threadedly installed on the vertical screw rod 7. And a vertical rod is fixedly installed in the C-shaped frame 6, and the vertical rod penetrates through the lifting plate 8 and is slidably connected to the lifting plate 8. And a frame 9 is fixedly installed on one side of the lifting plate 8. The internal dimension of the frame 9 is larger than the farthest distance between the two side plates 3, that is, the two side plates 3 can completely pass through the internal space of the frame 9, and the two will not interfere with each other. And a first chute 10 is provided on both sides of the frame 9. The same slide plate 11 is slidably installed in the two first chutes 10. And two baffles are fixedly installed on the slide plate 11. The two baffles are respectively in contact with the inner walls of the two sides of the frame 9 to ensure that the slide plate 11 will not move horizontally in the longitudinal direction and can only move horizontally in the transverse direction. And a top push head 12 is fixedly installed on the top of the slide plate 11. The top push head 12 is located inside the frame 9 and is below the concave plate 4 at the same time.

[0026] In the above method, in order to firmly fix the slide plate 11 at a specified position, a clamping groove 13 is provided on the top of the slide plate 11, and a plurality of cross plates 14 are fixedly installed on the outer wall of one side of the frame 9. The number of the cross plates 14 is the same as the number of the concave plates 4. A half-threaded screw rod 15 is threadedly installed on each of the plurality of cross plates 14. The bottom end of one of the half-threaded screw rods 15 extends into the clamping groove 13. By using the insertion method of the half-threaded screw rod 15 and the clamping groove 13, the slide plate 11 can be reliably restricted at the specified position.

[0027] In this method, in order to ensure that the concave plate 4 can perform stable linear lifting, a plurality of second chutes 16 are provided on both of the two side plates 3. A square rod 17 is slidably installed in each of the plurality of second chutes 16. The square rod 17 is in contact with the inner wall of the second chute 16, and the mutually close ends of the corresponding two square rods 17 are fixedly connected to the corresponding concave plate 4. Through the sliding arrangement of the square rod 17 in the second chute 16, the concave plate 4 can only perform linear lifting.

[0028] In the present embodiment, in order to ensure that the concave plates 4 can be placed stably when not in use, an embedding groove 18 is opened on one side of the plurality of concave plates 4, a plurality of cylinders 20 are fixedly mounted on one side plate 3, a connecting strip 21 is fixedly mounted on the output shafts of the plurality of cylinders 20, an embedding rod 19 is fixedly mounted on one side of the plurality of connecting strips 21 close to the side plate 3, and one end of the plurality of embedding rods 19 penetrates the corresponding side plate 3 and extends into the corresponding embedding groove 18, and the embedding rod 19 is slidably connected to the corresponding side plate 3, and the embedding rod 19 is plugged into the embedding groove 18, so that the concave plate 4 is restricted in a specified position, and the concave plate 4 cannot move up and down without removing the plugging relationship, and in addition, the arrangement of the cylinder 20 and the connecting strip 21 does not affect the rise of the frame 9, and the internal space of the frame 9 is large enough.

[0029] The working principle of the lower limb rehabilitation exercise equipment provided by the utility model is as follows:

[0030] When exercising the patient's lower limbs, the patient is first made to lie on the bed board 1, and then the corresponding position of the push head 12 is adjusted according to the length and position of the patient's lower limbs. When adjusting, the half-thread screw 15 entering the clamping groove 13 is first screwed out. After being screwed out, the slide plate 11 loses the clamping limit, and then the slide plate 11 is toggled, and the slide plate 11 moves horizontally with the push head 12. When the push head 12 moves to the bottom of the designated concave plate 4, the corresponding half-thread screw 15 is rotated, and the bottom end of the half-thread screw 15 will gradually move toward the clamping groove 13, and finally the bottom end of the half-thread screw 15 will be inserted into the clamping groove 13 to restrict the slide plate 11, and then the output shaft of the corresponding cylinder 20 is started to extend, and the corresponding embedded rod 19 is brought out from the corresponding embedded groove 18. At this time, the concave plate 4 loses the clamping of foreign objects;

[0031] Then the motor is started in the forward direction, and its output shaft drives the vertical screw rod 7 to rotate. At this time, under the limit of the vertical rod, the lifting plate 8 will bring the frame 9 and the push head 12 up, and gradually, the two side plates 3, the cylinder 20 and the connecting strip 21 will pass through the internal space of the frame 9. When the push head 12 contacts the corresponding concave plate 4, it will rise against the concave plate 4, and the corresponding roller shaft 5 will pass through the corresponding movable opening 2. When it contacts the patient's lower limb, it will lift the lower limb. After the lower limb is lifted to a certain angle, the motor is started in the reverse direction, and the roller shaft 5 will drop, thereby lowering the lower limb. After that, the motor is started in the forward direction again, and the lower limb will be lifted again. This reciprocating motion is used to achieve the lifting exercise of the lower limb.

[0032] After the exercise is finished, the frame 9 is first brought back to the original position, and the corresponding concave plate 4 will fall naturally. After falling to the initial position, the output shaft of the corresponding cylinder 20 is started to retract, and the embedding rod 19 is brought back into the embedding groove 18.

[0033] Compared with the related art, the lower limb rehabilitation exercise equipment provided by the utility model has the following beneficial effects:

[0034] The utility model provides a lower limb rehabilitation exercise device. Through the provided roller shaft 5, and under the action of the vertical screw rod 7 and the lifting plate 8, the roller shaft 5 can be lifted and lowered, so that the patient's lower limbs can be lifted for multiple lifting rehabilitation exercises. The entire rehabilitation exercise process does not require manual lifting operations, which reduces the investment in labor costs. In addition, the design of multiple roller shafts 5 allows the corresponding roller shaft 5 to be selected according to the patient's body size or the lifting part, thereby improving the applicability.
