Description

Technical Field

[0001] This utility model relates to the field of hospital beds, and more specifically, to a foldable hospital bed. Background Technology

[0002] Medical beds generally cannot be folded. Even if they can be folded, they will use a canvas mattress, similar to single folding beds on the market. If there are multiple beds, they can be folded up when not in use to reduce the space required.

[0003] The utility model patent with authorization announcement number CN 214259710 U discloses a foldable intensive care unit bed, including a bed board with a cushioning pad installed on the top. The bottom feet of the bed board at both ends are connected to a support plate via hinges. A fixing block is provided on the inner side of the bottom of the bed board near the support plate. Armrests are welded to the left and right ends of the bed board and have armrest holes. The support plate, fixing blocks, and armrests all have screw holes of the same specification, and screws can be rotated into the screw holes. An IV stand socket is provided on the right side of the top of the bed board. In use, the screws are rotated into the support plate and fixing blocks to fix the bed. When the bed is in use, the cushioning pad provides a cushioning effect, the IV stand socket facilitates the installation of an IV stand, and the armrest holes facilitate the movement of the bed. When folded, the width from the bottom of the armrest to the bed board is greater than the width of the support plate. The support plate can be rotated to be below the armrest, and the screws can be rotated into the support plate and armrest to fold and fix the bed. The height of the fixing block can be selected according to the actual situation.

[0004] In the above-disclosed structure, the bed board is folded to install the support legs. However, this only reduces the height. It lacks a U-shaped bracket connecting the support plate for combined installation, so it cannot fold and retract the bed frame to reduce the length. This results in poor adaptability and an insignificant folding effect, which needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a foldable hospital bed. The bed can be connected and positioned by hinged trays on the side of the U-shaped bracket, which is convenient for combination and use.

[0026] Please see Figure 1 , Figure 4 and Figure 5A foldable hospital bed includes a U-shaped support 1. One side surface of the U-shaped support 1 has a combination hole 11, and the other side surface of the U-shaped support 1 is connected to a support plate 12. One end of the support plate 12 has notches 13 on both sides, and a hinge block 14 is hinged to the inner side of the notch 13. One end of the hinge block 14 is fixedly connected to one side surface of the U-shaped support 1. By installing the hinge block 14 through the notch 13, it can be combined and connected to the side of the U-shaped support 1, thus forming a flat bed board that can be used as a hospital bed. When folding is needed, the support plate 12 can be flipped downwards and vertically positioned to create a gap, allowing the U-shaped support 1 to be folded and retracted for easy combination and use. A sliding hole 15 is located in the middle of one side of the support plate 12. One end of the sliding hole 15 has a right-angle hole 16, the opening of which is located on the lower surface of the support plate 12. A combination rod 17 is slidably installed inside the sliding hole 15, and one end of the combination rod 17 is inserted into the combination... Inside hole 11, the other end of the combination rod 17 is fixedly connected to a clamping spring 18, which is slidably installed inside the sliding hole 15. One end of the combination rod 17 is fixedly connected to a pull rope 2, which is interactively connected to the inside of the right-angle hole 16. One end of the pull rope 2 is fixedly connected to a pull ring 21, which is slidably connected to the middle position of the lower surface of the support plate 12. A protective plate 19 is fixedly connected to the front side of the U-shaped bracket 1. When the combination rod 17 is inserted into the combination hole 11 and clamped and positioned by the clamping spring 18, the support plate 12 can be supported and positioned to ensure the stability of the docking installation. When disassembly is required, the pull ring 21 can be pulled from the bottom, which, together with the pull rope 2, compresses the clamping spring 18 with the combination rod 17, allowing it to retract into the sliding hole 15 and detach from the combination hole 11. The support plate 12 can then be hinged downwards and flipped for folding and retraction, which is convenient for adjustment. Then, multiple U-shaped brackets 1 can be slid together for easy folding and retraction, making it highly adaptable.

[0027] Please see Figure 1 , Figure 2 and Figure 3The U-shaped bracket 1 has fixed blocks 22 on both sides, a guide rod 23 on one side of the fixed block 22, and a guide ring 24 on the side of the U-shaped bracket 1. The guide ring 24 is slidably connected to the outer surface of the guide rod 23. One end of the guide rod 23 is fixedly connected to a limit block 25, which is located on the side of the guide ring 24. The guide rod 23 is located on both sides of the U-shaped bracket 1 and decreases in height in a stepped manner. The guide rod and the guide ring are connected by the fixed blocks and limited by the limit blocks, which can be connected and guided to each other. This facilitates sliding adjustment for unfolding and also facilitates shrinking and folding, avoiding interference and providing high adaptability. The stepped guide rods 23 are connected to the guide rings 24, thereby supporting multiple U-shaped brackets 1 to each other and ensuring the stability of the connection. During sliding adjustment, the guide can be limited to avoid misalignment and interference. The separated U-shaped brackets 1 can be interactively closed to reduce the length, which is convenient for storage and stability.

[0028] Please see Figure 1 and Figure 2 The U-shaped bracket 1 and the tray 12 are spaced apart and their two side surfaces are connected to each other. The upper surface of the tray 12 is flush with the upper end of the U-shaped bracket 1 and the tray 12 is hinged to one side surface of the U-shaped bracket 1. By distributing the U-shaped bracket and the tray at intervals, they can be combined and positioned together. When folding and shrinking, they can also be flipped to avoid each other, which is convenient for adjustment and use, and is stable and efficient.
