At the same time, the second telescopic drive 7 drives the leg bed board 9 to flip upward, realizing the leg lifting action. Then, the pivot 3 drives the buttock bed board 4 and the bracket 5 to rotate 90° simultaneously. After that, the second telescopic drive 7 drives the leg bed board 9 to flip downward, realizing the leg lowering action.
[0029] In this embodiment, a drive device 10 for driving the rotating shaft 3 to rotate is also included.
[0030] like Figure 5 As shown, the drive device 10 includes a drive arm 1001 fixed on the rotating shaft 3. A third telescopic drive member 1002 is provided on one side of the drive arm 1001. One end of the third telescopic drive member 1002 is rotatably connected to the connecting seat 1003, and the other end is rotatably connected to the drive arm 1001.
[0031] In this embodiment, a second support arm 901 extending downwards is fixed on one side of the leg bed board 9 near the buttock bed board 4. The second support arm 901 is rotatably connected to the telescopic end of the second telescopic drive member 7. A support rod 801 is provided at the bottom of the back bed board 8. Both ends of the support rod 801 are fixed to the back bed board 8. A first support arm 802 extending downwards is provided on the support rod 801. The first support arm 802 is rotatably connected to the telescopic end of the first telescopic drive member 6.
[0032] It should be noted that the first telescopic drive component 6, the second telescopic drive component 7, and the third telescopic drive component 1002 are all electric push rods. The electric push rods are controlled by a controller, which is electrically connected to a remote control.
[0033] It should be noted that both the bed frame crossbeam 1 and the connecting seat 1003 can be fixed to the bed frame. Example
[0034] like Figure 6As shown, in this embodiment, the drive device 10 includes a gear 1004 fixed on the rotating shaft 3. A rack 1005 meshes with one side of the gear 1004, and one end of the rack 1005 is connected to the telescopic end of the third telescopic drive member 1002. The third telescopic drive member 1002 is mounted and fixed on the bed frame.
[0035] A rack guide block is provided on the back of the rack 1005. The rack 1005 slides with the rack guide block, which is fixed on the bed crossbeam 1.
[0036] The remaining structures in this embodiment are the same as in Embodiment 1. Example
[0037] Based on the bed rotation mechanism of the nursing bed in Embodiment 1 or Embodiment 2, such as Figure 7 As shown, this embodiment also proposes a nursing bed, which includes a bed frame, the bed frame including two bed frame longitudinal beams 12 arranged side by side, both ends of the bed frame longitudinal beams 12 are provided with movable lifting frames 13, the bottom of the movable lifting frames 13 is provided with movable rollers 14, wherein the top of the movable lifting frame 13 near the leg bed board 9 is provided with an auxiliary extension bed board 15.
[0038] The movable lifting frame 13 includes two vertically arranged fixed legs 1301, with an upper crossbeam 1302 fixedly connected between them. Each fixed leg 1301 has a movable leg 1303 movably connected to it, and each movable leg 1303 has a caster 14 at its lower end. A lower crossbeam 1304 is fixedly connected between the two movable legs 1303. A vertically arranged fourth telescopic drive member 1305 is positioned between the lower crossbeam 1304 and the upper crossbeam 1302. The upper end of the fourth telescopic drive member 1305 is connected to the upper crossbeam 1302, and the lower end is connected to the lower crossbeam 1304. The fourth telescopic drive member 1305 can be an electric push rod.
[0039] In this embodiment, the fixed leg 1301 is fixed to the longitudinal beam 12 of the bed frame.
[0040] In addition to the working state disclosed in Embodiment 1 regarding the rotating mechanism of the nursing bed, this embodiment also provides another working state (working state two). Specifically, the first telescopic drive 6 drives the backrest board 8 to flip upwards, realizing the back-raising action; simultaneously, the second telescopic drive 7 drives the legrest board 9 to flip downwards, realizing the leg-lowering action, thus allowing the patient to sit up. The bed frame has a clearance space corresponding to the legrest board 9, so that the downward flipping of the legrest board 9 will not interfere with the bed frame. Example
[0041] Based on the nursing bed disclosed in Embodiment 3, in this embodiment, as... Figure 8As shown, the movable lifting frame 13 is connected to the bed frame longitudinal beam 12 via a longitudinal telescopic mechanism 16. Specifically, the longitudinal telescopic mechanism 16 includes a guide beam 1601 fixed to the fixed leg 1301. The guide beam 1601 is slidably inserted into the bed frame longitudinal beam 12, and its inner end is connected to a fifth telescopic drive member 1602, which is installed and fixed inside the bed frame longitudinal beam 12. An installation opening is provided on the bed frame longitudinal beam 12, through which the fifth telescopic drive member 1602 is inserted into the bed frame longitudinal beam 12. A cover plate is provided on the outside of the installation opening to shield it.
[0042] When the nursing bed is switched to the working state two described in Embodiment 3, the longitudinal telescopic mechanism 16 drives the movable lifting frame 13 to move inward to the bed frame, thereby reducing the overall length of the nursing bed and facilitating its movement.
