The turning over assist mechanism 7 includes a control compartment 71 fixedly connected to one end of the footboard 3, a placement plate 72 is movably connected to the inner side of the placement slot 4, a hydraulic cylinder 73 is fixedly connected to the inner wall of the control compartment 71, a connecting plate 74 is installed at the telescopic end of the front end of the hydraulic cylinder 73, a rack 75 is fixedly connected to the front end of the connecting plate 74, a gear plate 76 is meshed with the lower end of the rack 75, a transmission shaft 77 is fixedly connected to the inner side of the gear plate 76, a limiting ring 78 is fixedly connected to the outer side of the transmission shaft 77 near the gear plate 76, a limiting frame 79 is fixedly connected to the upper end of the limiting ring 78, and a blocking rod 710 is slidably connected to the inner side of the limiting frame 79.

[0023] In this embodiment, the front end of the rack 75 is fixedly connected to the sliding frame 711, and the inner side of the sliding frame 711 is slidably connected to the support rod 712. The transmission shaft 77 passes through the interior of the control chamber 71, and the transmission shaft 77 and the control chamber 71 are movably connected. The transmission shaft 77 extends to the interior of the footboard 3, and the transmission shaft 77 and the footboard 3 are movably connected. One end of the transmission shaft 77 is fixedly connected to one end of the placement plate 72, and the limiting frame 79 is in the shape of a circular arc. The axial center lines of the gear plate 76, the transmission shaft 77, the limiting ring 78, and the limiting frame 79 are located on the same straight line. One end of the blocking rod 710 is fixedly connected to the inner inner wall of the control chamber 71 near the side of the hydraulic cylinder 73, and the rear end of the support rod 712 is fixedly connected to the inner inner wall of the control chamber 71 near the upper side of the hydraulic cylinder 73.

[0024] Specifically, when the patient needs to turn over, the hydraulic cylinder 73 is first started, so that the hydraulic cylinder 73 pulls the connecting plate 74 to move toward the side close to the hydraulic cylinder 73, and then the connecting plate 74 drives the rack 75 to move. At the same time, the rack 75 drives the gear plate 76 to rotate, and the gear plate 76 drives the transmission shaft 77 to rotate, so that the transmission shaft 77 drives the limiting frame 79 to rotate through the limiting ring 78, and the limiting frame 79 is blocked by the inner stop rod 710, so that the rotation range of the limiting frame 79 is limited, and then the rotation of the transmission shaft 77 is limited, so that the transmission shaft 77 The placement plate 72 is driven to rotate within a specified rotation range, so that the patient can turn over at a small angle. The hydraulic cylinder 73 pulls the connecting plate 74 to move, so that the rack 75 drives the gear plate 76 to rotate, and the gear plate 76 drives the transmission shaft 77 to rotate. At the same time, the transmission shaft 77 drives the limiting frame 79 to rotate through the limiting ring 78, and the blocking rod 710 limits the rotation range of the limiting frame 79. This can facilitate the purpose of limiting the rotation of the transmission shaft 77, so that the transmission shaft 77 drives the placement plate 72 to rotate within a specified rotation range, so that the patient can rotate at a small angle.

[0027] Working principle:

[0028] When in use, the patient first lies on the upper end of the nursing bed plate 1, so that part of the patient's body is located on the placement plate 72, and then the medical staff hangs the water on the water hanging frame 8, so that the patient can be given water hanging treatment. When the patient needs to turn over, the hydraulic cylinder 73 is first started, so that the hydraulic cylinder 73 pulls the connecting plate 74 to move toward the side close to the hydraulic cylinder 73, and then the connecting plate 74 drives the rack 75 to move, and the rack 75 drives the sliding frame 711 to slide along the support rod 712, so as to improve the stability of the movement of the rack 75. At the same time, the rack 75 drives the gear plate 76 to rotate, and the gear plate 76 drives the transmission shaft 77 to rotate, so that the transmission shaft 77 drives the limiting frame 79 to rotate through the limiting ring 78, and the limiting frame 79 is restricted The blocking rod 710 on the inside thereof blocks the rotation range of the limiting frame 79, and further limits the rotation of the transmission shaft 77, so that the transmission shaft 77 drives the placement plate 72 to rotate within the specified rotation range, so that the patient can turn over at a small angle. The hydraulic cylinder 73 pulls the connecting plate 74 to move, so that the rack 75 drives the gear plate 76 to rotate, and the gear plate 76 drives the transmission shaft 77 to rotate. At the same time, the transmission shaft 77 drives the limiting frame 79 to rotate through the limiting ring 78, and the blocking rod 710 limits the rotation range of the limiting frame 79, which can achieve the purpose of facilitating the rotation limitation of the transmission shaft 77, so that the transmission shaft 77 drives the placement plate 72 to rotate within the specified rotation range, so that the patient can rotate at a small angle.
