The moving assembly includes a docking shell 10 fixedly connected to the bottom of the bed frame 1, with two rows of docking shells 10 at the bottom. A docking plate 11 is slidably connected to the sides of the bed frame 1 and the docking shells 10. A quick-change assembly is installed inside the docking shells 10. The quick-change assembly includes a slide rod 12, which is slidably connected inside the docking shells 10, connecting various structures. One end of the slide rod 12 is fixedly connected to a locking block 13, and the other end is rotatably connected to a rotating handle 14. Rotating the rotating handle 14 controls the slide rod 12 to move the locking block 13. A baffle 15 is fixedly connected to the bottom of the docking shells 10, and the slide rod 12 is slidably connected inside the baffle 15, protecting the internal structures of the docking shells 10. A spring 16 is sleeved around the outer periphery of the slide rod 12, positioned between the locking block 13 and the baffle 15. The pressure generated by the interaction of the spring 16 and the baffle 15 causes the locking block 13 to move upwards. The bottom of the docking plate 11 is provided with a slot 17. The locking block 13 is engaged with the slot 17. The locking block 13 moves upward and is inserted into the slot 17 to fix the position of the docking plate 11 and the handrail 33. The first type of handrail 33 is fixed by locking blocks 13 in one row of docking shells 10, and the second type of handrail 33 is fixed by locking blocks 13 in two rows of docking shells 10.

[0038] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8The multi-position rotating assembly includes a rotating column 1 20, a rotating column 24, a rotating column 3 27, and a rotating column 4 31. The rotating column 1 20 is rotatably connected to the bottom of the bed frame 1. A connecting plate 1 21 is fixedly connected to the side of the rotating column 1 20. The end of the connecting plate 1 21 is rotatably connected to the bottom of the leg frame 3. A connecting frame 1 22 is rotatably connected to the side of the rotating column 1 20. By rotating the rotating column 1 20 through the connecting frame 1 22, the leg plate 4 and foot plate 5 are controlled to descend or rise. An electric cylinder 1 23 is rotatably connected to the bottom of the bed frame 1. The connecting frame 1 22 is rotatably connected to the output end of the electric cylinder 1 23. The electric cylinder 1 23 is used to drive the connecting frame 1 22, which controls the rotation of the rotating column 1 20. Rotating column 24 is rotatably connected to the bottom of bed frame 1. Rotating plate 25 is fixedly connected to the outside of rotating column 24. The top of rotating plate 25 is equipped with pulleys. The pulleys of rotating plate 25 are in contact with the bottom of waist board 6. Electric cylinder 26 is installed at the bottom of bed frame 1. Rotating column 24 is rotatably connected to the output end of electric cylinder 26. Electric cylinder 26 drives rotating plate 25 to rotate through rotating column 24, pushing one side of leg board 4, foot board 5, waist board 6, back board 1 7 and back board 2 8 to flip. Rotating column 3 27 is rotatably connected to the bottom of bed frame 1. A rotating frame 28 is fixedly connected to the side of rotating column 3 27. The rotating frame 28 has pulleys that contact the bottom of back panel 1 7 and back panel 2 8. A connecting rod 29 is rotatably connected to the side of rotating column 3 27. An electric cylinder 30 is rotatably connected to the bottom of bed frame 1. The connecting rod 29 is rotatably connected to the output end of electric cylinder 30. Electric cylinder 30 drives rotating column 3 27 via connecting rod 29, rotating the rotating frame 28 and causing it to drag back panel 1 7 and back panel 2 8 to rotate. Rotating column 4 31 is rotatably connected to the bottom of bed frame 1. Rotating column 4 31 is fixedly connected to the rotating side of bedpan 9. An electric cylinder 4 32 is rotatably connected to the bottom of bed frame 1. Rotating column 4 31 is rotatably connected to the output end of electric cylinder 4 32. Electric cylinder 4 32 drives rotating column 4 31, rotating bedpan 9 to open it.

[0039] Reference Figure 3 and Figure 4 A positioning plate 18 is fixedly connected to the side of the docking plate 11. A positioning groove 19 is provided on the side of the bed frame 1. The positioning plate 18 is slidably connected inside the positioning groove 19. The installation positions of the docking plate 11 and the armrest 33 are fixed by the cooperation between the positioning plate 18 and the positioning groove 19.

[0040] Working principle: Rotating the rotary handle 14 pulls the locking block 13 downwards via the slide rod 12, causing the locking block 13 to disengage from the slot 17 of the docking plate 11, allowing the currently used armrest 33 to slide out. Then, the armrest 33 to be replaced is slid into the bed frame 1. When the first type of armrest 33 needs to be replaced, the quick-change assembly in one row of docking shells 10 is used. When the second type of armrest 33 needs to be replaced, the quick-change assembly in both rows of docking shells 10 is used. Rotating the rotary handle 14 in opposite directions moves the slide rod 12 upwards. With the help of the pressure applied to the locking block 13 by the spring 16, the slide rod 12 moves the locking block 13 upwards, and the locking block 13 engages inside the slot 17, completing the replacement of the armrest 33. This effectively improves the efficiency and convenience of replacing the armrest 33.

[0041] When electric cylinder 1 23 retracts, it controls the leg plate 4 and foot plate 5 to descend. When electric cylinder 2 26 extends, it rotates the rotating plate 25, causing the pulley on it to push the waist plate 6 on one side, causing the leg plate 4, foot plate 5, back plate 1 7 and back plate 2 8 on the same side to flip, so that the patient turns to the side. When electric cylinder 2 26 retracts, the patient turns to the other side. Electric cylinder 3 30 retracts, controlling the pulley on the rotating frame 28 to push the back plate 1 7 and back plate 2 8 to rotate upward. Electric cylinder 4 32 extends, pushing the rotating column 4 31 to rotate downward and open the bedpan plate 9, providing convenient space for the patient. Through the coordination of multiple position rotation functions, a better nursing experience is provided for the patient.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
