[0025] 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.

[0026] Reference Figure 1 、 Figure 2 and Figure 4 The present invention provides an embodiment of a multifunctional rehabilitation position conversion bed, comprising:

[0027] The front and rear ends of the waist frame 1 are fixedly connected to fixed shafts 4, and the two fixed shafts 4 are rotatably connected to the leg frames 7 and the head frame 5 respectively. Soft cushions 3 are provided inside the waist frame 1, the leg frames 7 and the head frame 5. The inner walls of the waist frame 1, the leg frames 7 and the head frame 5 are fixedly connected to support frames 14 to support the soft cushions 3. The top sides of the waist frame 1, the leg frames 7 and the head frame 5 are rotatably connected to locking blocks 8 to fix the soft cushions 3. The inner wall of the middle end of the waist frame 1 is fixedly connected to a waist support 2 to support the patient's waist. The top side of the rear soft cushion 3 is fixedly connected to a headrest 6 to improve the patient's comfort. A plurality of universal wheels are installed on the bottom side of the fixed frame 9 through a wheel frame.

[0028] Specifically, the leg frame 7 and the head frame 5 can both rotate around the fixed axis 4, and damping is provided between the leg frame 7, the head frame 5 and the fixed axis 4. The cushion 3 can be placed inside the waist frame 1, the leg frame 7 and the head frame 5, and a support frame 14 is provided inside the waist frame 1, the leg frame 7 and the head frame 5 to provide support for the cushion 3. At the same time, the locking block 8 on the top side of the waist frame 1, the leg frame 7 and the head frame 5 is provided with damping, and the cushion 3 can be fixed inside the waist frame 1, the leg frame 7 and the head frame 5 by the locking block 8. When the worn cushion 3 needs to be replaced, the worn cushion 3 can be disassembled from the inside of the waist frame 1, the leg frame 7 and the head frame 5 by rotating the locking block 8 to complete its replacement, which can improve the patient's comfort.

[0029] Reference Figure 2-Figure 4The top of the support shaft 13 is sleeved on the outer wall of the plug shaft 15 to provide support for the rotation of the top of the support shaft 13. One end of the two-way threaded rod 10 is fixedly connected to the bottom side of the waist frame 1, and the two-way threaded rod 10 is located on the outer wall of the fixed frame 9. The outer wall of the two-way threaded rod 10 is threadedly connected to two sliding shells 11. The top sides of the two sliding shells 11 are rotatably connected to the support shaft 13 to control the angle adjustment of the leg frame 7 and the head frame 5. When the angle of the leg frame 7 is rotated downward from the horizontal and the head frame 5 is rotated upward from the horizontal, the patient's calf and head can be supported respectively, which is convenient for adapting to the different usage needs of the patient and realizing the versatility of the rehabilitation posture conversion bed. The bottom sides of the front and rear support frames 14 are fixedly connected to the support blocks 17, and the plug shaft 15 is located inside the support block 17. The middle end of the plug shaft 15 and the end away from the support shaft 13 are threadedly connected with a nut 16. The top of the support shaft 13 is sleeved on the outer wall of the plug shaft 15 to provide support for the rotation of the top of the support shaft 13. One end of the two-way threaded rod 10 is fixedly connected to the handle 12 to rotate the two-way threaded rod 10;

[0030] Specifically, the rotating bidirectional threaded rod 10 can drive the sliding shell 11 to move on the outer wall of the bidirectional threaded rod 10 and drive the rotation of the support shaft 13, thereby realizing the angle adjustment of the leg frame 7 and the head frame 5 respectively, and adjusting the rehabilitation position conversion bed according to the patient's needs. When it needs to be folded, stored and transported, the plug shaft 15 can be pulled out from the inside of the support block 17, and the support shaft 13 and the support block 17 can be connected by two nuts 16. The top end of the support shaft 13 is set on the outer wall of the plug shaft 15, which can provide support for the rotation of the support shaft 13 on the outer wall of the support block 17. When the support shaft 13 is disengaged from the support block 17, the two support shafts 13 can be rotated and then the leg frame 7 and the head frame 5 can be flipped over. The leg frame 7 and the head frame 5 are flipped vertically between the waist frame 1, and the rehabilitation position conversion bed can be folded and stored, which is convenient for subsequent transportation.

[0031] Working principle: first, let the patient lie on the multi-functional rehabilitation posture conversion bed, and then drive the rotation of the two-way threaded rod 10 by rotating the handle 12, control the movement of the sliding shell 11 on the outer wall of the two-way threaded rod 10, drive the bottom end of the support shaft 13 to rotate on the outer wall of the sliding shell 11 and the top end to rotate on the outer wall of the support block 17, so as to control the angle adjustment of the leg frame 7 and the head frame 5. When the angle of the leg frame 7 is rotated downward from the horizontal and the head frame 5 is rotated upward from the horizontal, the patient's calf and head can be supported respectively, which is convenient for adapting to the different usage needs of the patient. At the same time, the cushion 3 can be removed from the inside of the waist frame 1, leg frame 7 and head frame 5 by rotating the locking block 8, and then replaced. At the same time, the plug-in shaft 15 can be pulled out from the inside of the support block 17 by unscrewing the nut 16, and the support shaft 13 and the support block 17 can be disassembled, and the head frame 5 and the leg frame 7 can be flipped downward around the fixed axis 4 for easy storage and transportation.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
