Referring to fig. 1 to 11, the invention comprises a bed underframe 1, a bed frame 2 is arranged on the bed underframe 1, a bed board is arranged on the bed frame 2, guardrails are arranged on two sides of the bed board, and baffles 7 are arranged at the bed head and the bed tail of the bed board. The bed board includes back bed board 3, middle bed board 4, shank bed board, and back bed board 3 rotationally is connected with bedstead 2 in the waist position, and middle bed board 4 fixed connection is on bedstead 2, and the shank bed board includes thigh portion bed board 5 and shank bed board 6, and the one end and the rotatable connection of bedstead 2, the other end and the rotationally connection of shank bed board 6 of 5 corresponding buttock of thigh portion bed board, the shank bed board 6 other end and bedstead 2 are connected along 2 length direction are movably. The bed base 1 and the frame 2 are connected by a first link mechanism, and the first link mechanism can incline the frame 2 as a whole in the longitudinal direction of the frame 2 and can also elevate the frame 2 as a whole. The bed frame 2 and the back bed board 3 are connected through a second connecting rod structure, and the second connecting rod structure can enable the back bed board 3 to be in a lifting or horizontal position. The bedstead 2 is connected with the leg bed board through a third connecting rod structure, and the third connecting rod structure can enable the leg bed board to arch upwards. The turning-over device also comprises a turning-over mechanism which can turn over the patient from side to side. The first link mechanism, the second link mechanism, the third link mechanism and the turnover mechanism are respectively driven by a first push rod motor 36, a second push rod motor 38, a third push rod motor 43 and a fourth push rod motor 23. The turning mechanism comprises a turning main shaft 8, as shown in fig. 2, the turning main shaft 8 is fixed on the bedstead 2 through two bearings positioned at the middle positions of the head and the tail of the bedstead 2, and the turning main shaft 8 is arranged along the length direction of the bedstead 2. The two sides of the turning main shaft 8 are both provided with turning wheel support arms 9, one end of each turning wheel support arm 9 is fixedly connected with the turning main shaft 8, and the other end of each turning wheel support arm extends in the direction far away from the turning main shaft 8 along the width direction of the bedstead 2. The turning-over wheel support arms 9 are arranged in a plurality and are arranged at intervals along the length direction of the turning-over main shaft 8 and are symmetrically arranged at two sides of the turning-over main shaft 8. The turning-over wheel support arm 9 is connected with a turning-over wheel support 10, and the turning-over wheel support 10 can rotate in a certain angle relative to the turning-over wheel support arm 9. The turning-over wheel support arm 9 is rotatably connected with the turning-over wheel support 10 through a pin shaft, as shown in fig. 3 and 4, the turning-over wheel support arm 9 is provided with a first plane 901 and a second plane 902 which form a certain angle, the turning-over wheel support 10 is provided with a third plane 101, when the turning-over wheel support 10 rotates around the turning-over wheel support arm 9, the third plane 101 is abutted against the first plane 901 or the second plane 902, and thus the turning-over wheel support 10 is limited to rotate relative to the turning-over wheel support arm 9 within an acute angle range formed by the first plane 901 and the plane 902. The turning-over wheel support 10 is rotatably connected with three turning-over wheels 11 through pin shafts, and the number of the turning-over wheels 11 can be three. A fourth push rod motor 23 is rotatably connected to the bedstead 2 through a pin shaft, an extending rod end of the fourth push rod motor 23 is rotatably connected with one end of the turn-over connecting rod 22 through a pin shaft, and the other end of the turn-over connecting rod 22 is fixedly connected with the turn-over main shaft 8. The bed board is provided with a through hole for the turning wheel 11 to pass through at the corresponding position. When the extension bar of the fourth push rod motor 23 extends or retracts, the turning main shaft 8 is driven to rotate, the turning support arm 9 positioned at one side of the turning main shaft 8 rises, the other side of the turning main shaft descends, the turning wheel bracket 10 and the turning wheel 11 at the rising side of the turning main shaft upwards penetrate through the through hole and are higher than the bed plate, so that one side of the body of the patient is lifted to be in a left side lying state or a right side lying state. The extension and retraction of the extension bar of the push bar motor 23 respectively drive the turning-over main shaft 8 to rotate along the clockwise direction and the anticlockwise direction, and the lateral lying state of the patient in the two directions is sequentially realized. The patient is in a left side lying state or a right side lying state, namely the left and right turning function of the application. Because the turning wheel supports 10 can rotate in a certain angle relative to the turning wheel support arms 9, when a patient is supported, the turning wheel supports 10 can present different angles according to the body curves of the patient under the combined action of the turning wheel support arms 9 and the pressure of the patient, and the support can make the patient feel comfortable. Meanwhile, the turnover wheel 11 can rotate, and can rotate in a small range when being subjected to the reaction force of a patient in the turnover process, so that the function of massaging the patient is achieved. The push rod control system further comprises a controller and an operation screen, wherein operation keys and a display screen are arranged on the operation screen, and the first push rod motor 36, the second push rod motor 38, the third push rod motor 43, the fourth push rod motor 23 and the operation screen are respectively connected with the controller in a communication mode. The extending states of the push rods of the first push rod motor 36, the second push rod motor 38, the third push rod motor 43 and the fourth push rod motor 23 correspond to the determined integral inclination angle of the bedstead 2, the tilting angle of the back bed board 3, the arching angle of the leg bed boards and the left-right turning angle of the turning mechanism. The first push rod motor 36, the second push rod motor 38, the third push rod motor 43 and the fourth push rod motor 23 can feed the extending state of the push rods back to the controller in real time, and the extending state of the push rods can be converted into corresponding angle values through the processing of the controller and control the display screen to display the angle values in real time. The controller can be set to be a PLC or a single chip microcomputer. Therefore, signals can be input to the controller through the operation keys to control the first push rod motor 36, the second push rod motor 38, the third push rod motor 43 and the fourth push rod motor 23 to act, so that the purpose of accurately controlling all angles is achieved.
