A supporting mechanism is arranged on each long straight board. A universal wheel 15 is installed at the bottom end of each long straight board to facilitate assisting the patient in lower limb rehabilitation training.

[0030] A slide bar is slidably arranged in each fixed rod 2. The slide bar is connected to the fixed rod 2 by a fixing member. A support frame 5 is fixedly connected between the two slide bars, and a workbench 7 is fixedly arranged on the upper end of the support frame 5. A limit hole 4 is provided on each of the fixed rod 2 and the slide bar. The fixing member is a limit bolt 3 adapted to the limit hole 4. The slide bar is mounted on the fixed rod 2 by the limit bolt 3.

[0031] The support mechanism includes a plurality of support legs 14. A second slide groove 21 is provided in the long straight plate. A slide plate 19 is slidably provided in the second slide groove 21. There are four support legs 14. Two support legs 14 form a group. The two support legs 14 in the same group are fixedly provided at the bottom end of the same slide plate 19. The support leg 14 extends through the long straight plate on the base 1 to the bottom of the long straight plate on the base 1. A spring 25 is sleeved on the support leg 14, one end of the spring 25 is fixedly connected to the slide plate 19, and the other end of the spring 25 is fixedly connected to the inner wall of the second slide groove 21. The slide plate 19 is transmission-coordinated with the drive mechanism through a linkage.

[0032] A connecting rod 11 is fixedly provided on one side of the upper end of the long straight plate on the base 1 away from the fixed rod 2, and a support rod 10 is fixedly connected between the connecting rod 11 and the corresponding fixed rod 2. The driving mechanism includes a motor 18. A first slide groove 9 is provided on the support rod 10. The first slide groove 9 is a through groove that penetrates the support rod 10. A slider 26 is slidably provided in the first slide groove 9. A sliding frame 16 is fixedly connected between the two sliders 26. The seat 20 is fixedly provided at the upper end of the sliding frame 16. A screw rod 13 is rotatably provided in the first slide groove 9, and the screw rod 13 is threadedly connected to the slider 26. The motor 18 is fixedly installed on the fixed rod 2, and the output end of the motor 18 passes through the fixed rod 2 and is coaxially fixedly connected to the screw rod 13.

[0033] There are two groups of linkage parts, which are respectively arranged on the corresponding long straight plates. The linkage parts include a first rack 24, a second rack 27, and a gear 22. The bottom end of each slider 26 is fixedly connected to the first connecting plate 12, and the second rack 27 is fixedly arranged at the end of the corresponding first connecting plate 12 away from the sliding frame 16. A fixed seat 17 is fixedly arranged on the long straight plate, and a rotating shaft 23 is rotatably arranged on the fixed seat 17. The gear 22 is fixedly sleeved on the rotating shaft 23. The gear 22 is meshed with the second rack 27. The first rack 24 is fixedly arranged on the upper end of the slide plate 19, and the first rack 24 passes through the long straight plate and extends out of the long straight plate, and the first rack 24 is meshed with the gear 22.

[0034] In summary, in the initial state, the second rack 27 is disengaged from the gear 22, and the first rack 24 is meshed with the gear 22. The support leg 14 is located below the base 1 but is not in contact with the ground.

[0035] The height of the workbench 7 is adjusted by the limit bolt 3 to facilitate use by patients of different heights. The limit bolt 3 is turned, the limit bolt 3 is removed, the workbench 7 is adjusted to a suitable height, and then the slide bar is fixedly installed on the fixed rod 2 by the limit bolt 3, so that the support frame 5 is fixed.

[0036] After the height is adjusted, the patient can use the device to perform lower limb rehabilitation training by holding the handle 6. After a long period of training, the patient can rest on the seat 20. By starting the motor 18, the output end of the motor 18 drives the screw rod 13 to rotate, and the screw rod 13 moves the slider 26, and the slider 26 moves the seat 20 through the sliding frame 16.

[0037] At the same time, the sliding frame 16 moves with the first connecting plate 12, and the first connecting plate 12 moves with the second rack 27. As the second rack 27 moves, the second rack 27 meshes with the gear 22 to rotate the gear 22, and the gear 22 moves the first rack 24 downward, and the first rack 24 moves the slide plate 19 downward, and the slide plate 19 moves the supporting leg 14 downward, and the universal wheel 15 gradually separates from the ground, and the supporting leg 14 contacts the ground to support and fix the whole, preventing the universal wheel 15 from contacting and sliding with the ground, thereby causing irreversible effects. The spring 25 is compressed during the downward movement of the slide plate 19. After the supporting leg 14 contacts the ground, the gear 22 and the first rack 24 are still in meshing state. Until the position of the seat 20 is adjusted, the patient can sit on the seat 20 to rest by himself. The motor 18 stops.

[0038] After the rest is completed, the motor 18 reverses, the screw rod 13 reverses, and the slider 26 moves in the opposite direction. The slider 26 returns the seat 20 to the initial position through the sliding frame 16. In this process, the sliding frame 16 moves the second rack 27 through the first connecting plate 12, and the second rack 27 meshes with the gear 22 to rotate the gear 22. The gear 22 causes the first rack 24 to move upward with the skateboard 19 and the support leg 14, and the support leg 14 is separated from the ground, and the universal wheel 15 is in contact with the ground. As the sliding frame 16 moves, the second rack 27 is separated from the gear 22 until it returns to the initial state, and the motor 18 stops.

[0039] Example 2

[0040] like Figure 6-Figure 8 The present embodiment is different from the first embodiment in that the linkage structure for moving the supporting mechanism is different, and the other identical parts will not be described in detail here.

[0041] The linkage member includes an inclined surface block 29. The inclined surface block 29 is fixedly arranged at the upper end of the slide plate 19, and the upper end of the inclined surface block 29 on the side close to the workbench 7 is inclined in the direction of the connecting rod 11. A second connecting plate 28 is fixedly arranged at the bottom end of the slide block 26. The end of the bottom end of the second connecting plate 28 close to the inclined surface block 29 is an arc surface. A clearance groove 30 connected to the second slide groove 21 is opened on the upper end surface of the long straight plate, and the inclined surface block 29 is in the clearance groove 30. The inclined surface block 29 is abutted and matched with the end of the second connecting plate 28.

[0042] In summary, when the slider 26 moves the seat 20 through the sliding frame 16, the slider 26 moves with the second connecting plate 28. When the second connecting plate 28 moves to the inclined block 29, the second connecting plate 28 abuts against the inclined block 29 to make the inclined block 29 move the slider 19 downward. The slider 19 moves downward with the supporting leg 14. When the supporting leg 14 contacts the ground, the whole is fixed to prevent the universal wheel 15 from contacting the ground and rolling accidentally, which may cause the patient to fall.

[0043] When the patient is not resting on the chair 20, the motor 18 reverses to move the slider 26 in the opposite direction, and the slider 26 returns the chair 20 to the initial position through the sliding frame 16. In this process, the slider 26 moves with the second connecting plate 28, and the second connecting plate 28 gradually separates from the inclined block 29. The slide plate 19 moves upward under the action of the spring 25 and returns to the initial state. After the chair 20 returns to the initial state, the motor 18 stops.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
