After the technical scheme is adopted, the invention has the following effects: the bed board overturning driving mechanism comprises a driving shaft, two driving arms and a linear power device, wherein the two driving arms are respectively hinged to the inner sides of corresponding longitudinal beams of the bed board, the driving shaft is connected to one ends of the two driving arms, idler wheels are arranged at the other ends of the two driving arms, a linear guide rail matched with the idler wheels is arranged at the bottom of the bed board, a driving arm is fixed on the driving shaft, the linear power device is hinged between the driving arm and the bed board, a clutch is arranged on the linear power device, a driven arm is further rotatably arranged on the driving shaft, the damper is hinged between the driven arm and the bed board, a buffer force application sleeve is fixed on the driving shaft, a dumping buffer shifting block and a resetting shifting block are arranged on the buffer force application sleeve at a circumferential interval, the dumping buffer shifting block is in extrusion contact with the driven arm to compress the damper when the bed board is lifted and overturned, the resetting shifting block is in extrusion contact with the driven arm to enable the damper to stretch and reset, and when the bed board is required to be overturned, the linear power device drives the driving arm to deflect, and then the driving arm deflects and the driving arm is enabled to rotate along with the driving arm to be integrally pushed by the reset driving arm, and the reset driving arm is enabled to deflect along with the reset point, and the reset driving arm is enabled to rotate and the reset driving arm to deflect along with the reset and the reset driving arm to rotate; when the bed plate needs to be laid down, the clutch of the linear power device is separated to further disconnect the power and the driving arm, so that the bed plate deflects and descends due to the gravity of the bed plate and the gravity of a patient, the driving arm and the driving shaft deflect reversely when the bed plate deflects, and before the laid down buffer shifting block is not contacted with the driven arm, the bed plate is laid down very smoothly, so that the rapid laid down can be realized, and when the laid down buffer shifting block is not contacted with the driven arm, the damper plays a role, so that the buffer effect is realized, and the bed plate is laid down slowly; thus, the time for laying down the bed board is shortened, and the bed board is suitable for some emergency special cases. Meanwhile, as the bed board is not driven by the linear power device but deflected by dead weight, if the hands of a patient are positioned between the bed board and the bed frame during the falling process, the risk of pinch-off can not occur; if the hand of nursing staff is located between bed board and the bedstead, when the bed board is laid down, nursing staff can in time take out, and the bed board can receive the resistance effect of nursing staff's hand and laid down more slowly even do not lay down simultaneously, and the security is higher like this.
Because the driven arm comprises two arm plates and a buffer matching plate part connected between the two arm plates, one ends of the two arm plates are sleeved between the driving shafts, the other ends of the two arm plates are hinged with one ends of the dampers, the buffer force application sleeve is positioned between the two arm plates, the falling buffer shifting block and the reset shifting block are positioned on the periphery of the buffer force application sleeve, two side surfaces of the buffer matching plate part are respectively in extrusion contact fit with the falling buffer shifting block and the reset shifting block, the driven arm and the buffer force application sleeve are very convenient to install, and meanwhile the falling buffer block and the reset shifting block can be accurately in contact fit with the buffer matching plate part, so that the buffer action and the quick falling action are ensured to be reliable.
Because the turnover mechanism comprises two sets of connecting rod mechanisms connected between the longitudinal beam of the bed frame and the bed board, each set of connecting rod mechanism comprises a first hinge arm and a second hinge arm, one ends of the first hinge arm and the second hinge arm are respectively hinged on the inner side of the longitudinal beam of the bed frame, the other ends of the first hinge arm and the second hinge arm are respectively hinged on the bottom of the bed board, the length of the first hinge arm is longer than the size of the second hinge arm, the turnover mechanism is reasonable in structure, the bed board not only realizes the turnover action, but also has displacement in the horizontal direction, and thus when a patient lies on the medical bed, the turnover of the bed board can not extrude the abdomen of the patient, and thus the abdomen decompression effect is achieved.
And because the bed frame is provided with the supporting seat, the rollers are in supporting fit with the upper surface of the supporting seat when the bed board is laid down. Thus, the bed board is supported by the supporting seat after being laid down, and the bed board is stable and reliable.
And as the two sides of the bottom of the bed board are fixedly connected with the connecting seats, the first articulated arm and the second articulated arm are respectively articulated on the connecting seats, and a synchronous connecting shaft is connected between the two connecting seats, the connecting seats facilitate the first articulated arm and the second articulated arm to be respectively articulated, and the connecting rod mechanisms on the two sides of the bed board can synchronously act through the synchronous connecting shafts.
The connecting seat is matched with the polish rod section of the hinge bolt, a gasket is arranged between the first hinge arm and the connecting seat, the nut is arranged on the screw section of the hinge bolt and locked, an oil hiding ring groove is arranged on the hinge bolt, the position of the oil hiding ring groove is matched with the fixing sleeve, and after lubricating oil is added to the connecting structure of the hinge shaft, the oil hiding ring groove can store lubricating oil, so that long-term lubrication is kept, and long-time smooth rotation is ensured.
And as the limiting plate is arranged at one end, close to the second hinge arm, of the bottom of the bed plate, the lifting and overturning angles of the bed plate are limited by limiting and matching of the limiting plate and the second hinge arm, so that the overturning angles of the bed plate can be limited, and the overturning transition of the bed plate is avoided.
