[0028] Reference Figure 1-4 As shown, this embodiment discloses a nursing cart, including a nursing cart 1 , a limiting device 2 is provided on the upper surface of the nursing cart 1 , and an auxiliary device 3 is provided on one side of the nursing cart 1 .
[0029] Reference Figure 1-4 As shown, the limiting device 2 includes several limiting rings 21, and the several limiting rings 21 are fixedly connected to the upper surface of the nursing cart 1. The upper surface of the limiting ring 21 is fixedly connected with an L-shaped plate 22, and the surface of the L-shaped plate 22 is threadedly connected with a screw 23. One end of the screw 23 is rotatably connected to a movable plate 24, and the movable plate 24 is fixedly connected to two mutually symmetrical triangular plates 25 by means of a support rod. A fixing rod 26 is slidingly inserted into the limiting ring 21 corresponding to the triangular plate 25. One end of the fixing rod 26 is located inside the limiting ring 21 and is fixedly connected with a splint 27. The other end of the fixing rod 26 is fitted with the inclined surface of the triangular plate 25. The arc surface of the fixing rod 26 is covered with a spring 28, and the two ends of the spring 28 are respectively fixedly connected to the splint 27 and the limiting ring 21. When the nursing cart 1 needs to be used to place the medicine bottle, the staff places the medicine bottle in the limiting ring 21. At this time, the staff rotates the screw 23 on the L-shaped plate 22, and the screw 23 moves the movable plate 24 and the triangular plate 25. The inclined surface of the triangular plate 25 squeezes the fixed rod 26, and the fixed rod 26 brings the two splints 27 closer to each other, and the spring 28 is deformed. Finally, the two splints 27 squeeze the medicine bottle against each other, thereby achieving the effect of fixing the medicine bottle. When the medicine bottle needs to be taken out, the staff rotates the screw 23 in the opposite direction, and the triangular plate 25 moves away from the fixed rod 26. The fixed rod 26 moves back to its original position under the action of the reset elastic force of the spring 28, and the splint 27 loosens the fixation of the medicine bottle. The effect of fixing the medicine bottle is achieved through the limiting device 2, thereby preventing the medicine bottle from shaking during the movement of the nursing cart 1, thereby causing the medicine inside the medicine bottle to spill out.
[0030] Reference Figure 1-4As shown, two mutually symmetrical limiting rods 211 are slidably inserted on the surface of the movable plate 24, and one end of the limiting rod 211 is fixedly connected to the limiting ring 21. By providing the limiting rod 211, the effect of limiting the moving direction of the movable plate 24 is achieved, thereby improving the stability of the movement of the movable plate 24. Two mutually symmetrical telescopic rods 210 are fixedly connected to one side of the splint 27, and one end of the telescopic rod 210 is fixedly connected to the inner wall of the fixed ring. By providing the telescopic rod 210, the effect of limiting the moving direction of the splint 27 is achieved, thereby preventing the splint 27 from rotating and improving the stability of the movement of the splint 27. A rubber pad 29 is fixedly connected to the side of the splint 27 away from the fixed rod 26, and the size of the rubber pad 29 is adapted to the size of the splint 27. By providing the rubber pad 29, the effect of protecting the medicine bottle is achieved, thereby preventing the splint 27 from damaging the medicine bottle.
[0031] Reference Figure 1-4 As shown, the auxiliary device 3 includes two symmetrical guide tubes 31, one end of each guide tube 31 is fixedly connected to the nursing cart 1, and a guide rod 32 is slidably connected to the inside of the guide tube 31. One end of the guide rod 32 is fixedly connected to the handle 37. The arc surface of the guide tube 31 is threaded with a bolt 33, and the arc surface of the guide rod 32 is provided with a plurality of threaded holes 38. The size of the bolt 33 matches the size of the threaded holes 38. When the height of the handle 37 needs to be adjusted, the staff first moves the handle 37, and the handle 37 moves with the guide rod 32 in the guide tube 31, thereby changing the total length of the guide rod 32 and the guide tube 31. When the handle 37 is moved to the appropriate height, the staff rotates the bolt 33, and the bolt 33 passes through the guide tube 31 and is inserted into the threaded hole 38 of the guide rod 32, thereby achieving the effect of fixing the guide rod 32 and the guide tube 31. The auxiliary device 3 achieves the effect of adjusting the height of the handle 37, thereby facilitating the pushing of the nursing cart 1 by medical staff of different heights, thereby improving the practicality of the nursing cart 1.
[0032] Reference Figure 1-4As shown, one end of the bolt 33 is fixedly connected to two mutually symmetrical control blocks 35, and the surfaces of the two control blocks 35 are provided with anti-slip grooves. The provision of the control blocks 35 increases the contact area between the staff's hand and the bolt 33, thereby facilitating the staff's rotation of the bolt 33 and bringing convenience to the staff. The arc surface of the guide rod 32 is fixedly connected to two limiters 36, and the two limiters 36 are centrally symmetrical. The provision of the limiters 36 achieves the effect of limiting the movement direction of the guide rod 32 and the guide tube 31, preventing the guide rod 32 from rotating in the guide tube 31, which would cause the bolt 33 to be misaligned with the threaded hole 38 of the guide rod 32. The arc surface of the handle 37 is covered with a rubber sleeve 34, and the arc surface of the rubber sleeve 34 is provided with anti-slip grooves. The provision of the rubber sleeve 34 increases the friction between the staff's hand and the handle 37, making it easier for the staff to move the handle 37.
[0033] Working principle: When the nursing cart 1 needs to be used to place the medicine bottle, the staff places the medicine bottle in the limiting ring 21. At this time, the staff rotates the screw 23 on the L-shaped plate 22, and the screw 23 moves with the movable plate 24 and the triangular plate 25. The inclined surface of the triangular plate 25 squeezes the fixed rod 26, and the fixed rod 26 brings the two splints 27 closer to each other, and the spring 28 is deformed. Finally, the two splints 27 squeeze the medicine bottle against each other with the help of the rubber pad 29, thereby achieving the effect of fixing the medicine bottle. When the medicine bottle needs to be taken out, the staff rotates the screw 23 in the opposite direction, and the triangular plate 25 moves away from the fixed rod 26. The fixed rod 26 moves back to its original position under the action of the reset elastic force of the spring 28, and the splint 27 loosens the fixation of the medicine bottle. The effect of fixing the medicine bottle is achieved through the limiting device 2, thereby preventing the medicine bottle from shaking during the movement of the nursing cart 1, thereby causing the medicine inside the medicine bottle to spill out.
[0034] When the height of the handle 37 needs to be adjusted, the staff first holds the rubber sleeve 34 to move the handle 37, and the handle 37 moves with the guide rod 32 in the guide tube 31, and the total length of the guide rod 32 and the guide tube 31 changes. When the handle 37 moves to a suitable height, the staff rotates the bolt 33 through the control block 35, and the bolt 33 passes through the guide tube 31 and is inserted into the threaded hole 38 of the guide rod 32, thereby achieving the effect of fixing the guide rod 32 and the guide tube 31. The height of the handle 37 is adjusted by the auxiliary device 3, thereby facilitating medical staff of different heights to push the nursing cart 1, thereby improving the practicality of the nursing cart 1.
