Since the two second movable support rods 9 are movably pin-connected, the top of the second movable support rod 9 can pull the transverse slider 3 to slide on the transverse slider 4, and the thrust can be applied to the bed board 2 to push the bed board 2 upward, so that the height of the bed board 2 can be adjusted. The bed board 2 can be adjusted to a suitable height according to the patient's condition. After the patient lies on the bed board 2, the bed board 2 can be adjusted to a suitable height according to the patient's actual requirements, which can improve the convenience of the patient getting in or out of bed.

[0036] like Figure 1 and Figure 2 As shown, a fixed plate 10 and a support plate 11 are provided on both sides of the support base plate 5. The support base plate 5 is fixedly connected to the fixed plate 10, and the support plate 11 is fixedly connected to the bed board 2. A vertical slide groove 13 is provided inside the fixed plate 10, and a vertical slider 12 is provided inside the vertical slide groove 13. The vertical slider 12 is partially adapted to the vertical slide groove 13, and the vertical slider 12 is fixedly connected to the support plate 11. When the bed board 2 moves, the bed board 2 and the support plate 11 move synchronously, and the vertical slider 12 at the bottom of the support plate 11 moves inside the vertical slide groove 13. The moving trajectory of the vertical slider 12 can be limited by the vertical slide groove 13, and the bed board 2 can be prevented from being tilted by the fixed plate 10 and the support plate 11.

[0037] like Figure 1 and Figure 5 As shown, movable screw rods 21 are penetrated on both sides of the interior of the bed board 2, and a screw slider 22 is sleeved on the outside of the movable screw rod 21. The screw slider 22 is fixedly connected to the supporting base column 14, and a handle 41 is fixedly connected to the input end of the movable screw rod 21. The handle 41 can rotate the movable screw rod 21 to drive the screw slider 22 to move. Since the screw slider 22 is fixedly connected to the supporting base column 14, the supporting base column 14 can be pushed to move, thereby moving the supporting base column 14 to a suitable position, and the supporting base column 14 can be adjusted to a suitable position according to the hand of the heavier person or the infusion site.

[0038] like Figure 1 and Figure 2As shown, a fixing rod 24 is arranged inside the fixing frame 23, and limiting blocks 25 are penetrated at both ends of the fixing rod 24, and a limiting spring 26 is connected between the fixing rod 24 and the limiting block 25. A limiting hole 27 is arranged at the top end of the first movable support rod 20, and the limiting block 25 is adapted to the limiting hole 27. One end of the limiting block 25 can be inserted into the limiting hole 27 through the limiting spring 26, so that the fixing rod 24 can be connected to the first movable support rod 20, and the position of the fixing frame 23 can be limited. Conversely, the limiting block 25 can be pushed to compress the limiting spring 26, and the limiting block 25 can be separated from the limiting hole 27, so that the fixing frame 23 can be removed, and the quickness of disassembling and assembling the fixing frame 23 can be improved.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, a guide groove 29 is opened at the upper part of the fixed rod 24, a guide rack 31 is fixed at the lower part of the fixed rod 24, a plurality of movable rollers 30 are arranged at the top of the movable frame 28, and two movable gears 33 are arranged at the bottom of the movable frame 28. The movable gears 33 are meshed with the guide racks 31, and the bottom of the movable roller 30 extends into the guide groove 29, which can push the movable frame 28 to move along the fixed frame 23. At this time, the movable roller 30 provides rolling support for the movable frame 28, and the movable roller 30 can roll along the guide groove 29, and the movable gear 33 at the bottom of the movable frame 28 rolls along the guide rack 31, which can keep the movable frame 28 moving horizontally and avoid the movable frame 28 from being skewed. The movable frame 28 can be adjusted to a suitable position according to the patient's infusion position.

[0040] like Figure 1 and Figure 4 As shown, a pull rod 32 is passed through one side of the movable frame 28, and a locking tooth block 35 is fixed at one end of the pull rod 32. A locking spring 34 is sleeved on the outside of the pull rod 32, and the locking tooth block 35 is meshed with the movable gear 33. The locking spring 34 applies elastic force to the locking tooth block 35, so that the locking tooth block 35 is meshed with the movable gear 33, thereby limiting the position of the movable frame 28. Conversely, the locking tooth block 35 can be pulled by the pull rod 32 to compress the locking spring 34, so that the locking tooth block 35 can be separated from the movable gear 33. At this time, the movable frame 28 can move on the fixed rod 24.

[0041] Working principle: First, according to the patient's condition, the hydraulic cylinder 7 can push the bottom of the second movable support rod 9 to move through the connecting block 8. Since the two second movable support rods 9 are movably pinned, the top of the second movable support rod 9 can push the transverse slide block 3 to slide on the transverse slide bar 4, and the pulling force can be applied to the bed board 2 to pull the bed board 2 downward, and the bed board 2 can be adjusted to a suitable position, and the patient can lie on the bed board 2. Conversely, the hydraulic cylinder 7 can pull the connecting block 8 to move and lift the bed board 2 to a suitable position;

[0042] Secondly, one end of the limiting plug 25 can be inserted into the limiting plug hole 27 through the limiting spring 26, and the fixing rod 24 can be connected to the first movable support rod 20 to limit the position of the fixing frame 23. Then, the infusion bag can be placed inside the placement rack 40, and then the turntable 36 can be rotated around the T-shaped shaft 38, and the hook 37 at the bottom of the turntable 36 can be aligned with the infusion bag, and the infusion bag can be hooked by the hook 37, or the infusion bottle 39 can be placed inside the placement rack 40, and the bottom of the infusion bottle 39 can be passed through the bottom of the placement rack 40, and the placement rack 40 can provide support for the infusion bottle 39;

[0043] Secondly, the locking tooth block 35 can be pulled by the pull rod 32 to compress the locking spring 34, so that the locking tooth block 35 can be separated from the movable gear 33. At this time, the movable frame 28 can move on the fixed rod 24. Then, according to the patient's infusion position, the movable frame 28 can be pushed to move along the fixed frame 23. At this time, the movable roller 30 provides rolling support for the movable frame 28. The movable roller 30 can roll along the guide groove 29. The movable gear 33 at the bottom of the movable frame 28 rolls along the guide rack 31, which can keep the movable frame 28 moving horizontally. The movable frame 28 is adjusted to a suitable position, and the locking spring 34 applies elastic force to the locking tooth block 35, so that the locking tooth block 35 is meshed with the movable gear 33, thereby limiting the position of the movable frame 28.

[0044] Then, the turning handle 15 can rotate the transverse worm 16 to drive the transverse worm wheel 17 to rotate. Since the transverse worm wheel 17 is fixedly connected to the vertical screw rod 19, the transverse worm wheel 17 can rotate the vertical screw rod 19 to push the screw sleeve 18 to move. Since the screw sleeve 18 is fixedly connected to the first movable support rod 20, the screw sleeve 18 can be moved synchronously with the first movable support rod 20. According to the patient's infusion requirements, the extension length of the first movable support rod 20 can be flexibly adjusted and the height of the fixed frame 23 can be adjusted. The fixed frame 23 can be adjusted to a suitable position and infusion height. Then, the handle 41 can rotate the movable screw rod 21 to drive the screw slider 22 to move. Since the screw slider 22 is fixedly connected to the support bottom column 14, it can push the support bottom column 14 to move, so that the support bottom column 14 can be moved to a suitable position. The support bottom column 14 can be adjusted to a suitable position according to the hand of the patient or the infusion site.
