[0035] When in use, the patient lies on the middle plate 1, and when he needs to turn over, the electric push rod 29 is turned on. The electric push rod 29 controls the driving frame 7 to move, and the driving frame 7 controls the active rack 8 and the driving rack 17 to move. There is a gap between the active rack 8 and the angle tooth 6. The active rack 8 needs to move for a certain period of time before it will mesh with the angle tooth 6. When the driving rack 17 moves, it will drive the driving gear 16 meshed with it to rotate. The driving gear 16 controls the driving plate 18 and the stop plate 19 to rotate through the connecting shaft 20. The driving plate 18 drives the driving column 21 thereon to rotate, and the driving column 21 drives the driven column 23 meshed with it at a right angle to rotate. The driven column 23 drives the driven plate 22 to rotate, and the driven plate 22 drives the telescopic universal coupling to rotate. The telescopic universal coupling drives the active bevel gear 12 at the other end to rotate. According to the setting of the active bevel gear 12, such as Figure 4 As shown, when the active bevel gear 12 rotates, the driven bevel gear 11 meshing with it rotates in the same direction, so that the two cloth rolling shafts 9 rotate in the same direction, so that one cloth rolling shaft 9 puts the mattress 10, and the other cloth rolling shaft 9 rolls the mattress 10, and the mattress 10 moves, and then it will be as shown in FIG. Fig.10 As shown, the patient on the mattress 10 is moved to one side of the bed board 3 to prepare for subsequent turning over;

[0036] At the same time, when the electric push rod 29 controls the driving frame 7 to continue to move, the driving gear 16 on the driving frame 7 controls the driving plate 18 and the stop plate 19 to continue to rotate. At this time, the stop plate 19 rotates to the section 24 on the driven plate 22, such as Fig.11 As shown, when the stop plate 19 rotates again, the driven plate 22 will not rotate, and the Fig.12 As shown, the stop plate 19 moves along the cut surface 24, and limits the driven plate 22 through the cut surface 24. At the same time, the active rack 8 and the angle tooth 6 corresponding to one side are in contact and meshing. The active rack 8 moves to drive the angle tooth 6 on one side to move. According to the sliding limit of the slider 5 and the arc-shaped slide rail 4, the angle tooth 6 will drive the slider 5 to slide along the arc. At this time, Fig.13 As shown, the side plate 2 changes its angle to lift the patient, making it easier for the patient to turn over and lie on his side; when the side plate 2 changes its angle, the setting of the telescopic universal coupling can change its angle accordingly, and the telescopic universal coupling can also rotate after being reset;

[0037] By turning on the electric push rod 29 to drive the mattress 10 to move and then drive the side plate 2 to change its angle, the patient can be turned over by driving one electric push rod 29, which is more convenient to use; the two side plates 2 have the same structure, and when the electric push rod 29 is controlled to contract or extend, one of the side plates 2 will be driven to rotate to turn the patient over, which is convenient for turning the patient in two directions;

[0038] By controlling the electric push rod 29 to reset, the side plate 2 is rotated and reset first, thereby driving the driving rack 17 on the frame 7 to drive the driving gear 16 to rotate, thereby driving the two cloth rolling shafts 9 to rotate through the intermittent rotating mechanism, and resetting the mattress 10, so that the normal lying position can be achieved;

[0039] With the setting of the limiting slide rail 13, the mattress 10 will always slide and fit with the middle plate 1. When the mattress 10 on the side plate 2 rotates to change the angle, the position of the mattress 10 on the middle plate 1 remains unchanged, which is convenient for better assisting turning over; when the mattress 10 on the side plate 2 rotates to change the angle, if the mattress 10 is too tight, the auxiliary strip 30 will slide to give the mattress 10 on the side plate 2 space to rotate and change the angle, preventing the mattress 10 from being too tight and affecting the normal change of the angle of the side plate 2. When the side plate 2 is reset, the mattress 10 becomes loose, and the auxiliary strip 30 is controlled to reset by the spring 32, and it can be used normally, which is convenient for assisting turning over;

[0040] Due to the setting of the fastening buckle 33, when the mattress 10 is too soft, the slide groove 14 on the mattress 10 is easy to disengage from the limiting slide rail 13, and the setting of the fastening buckle 33 has been sliding and limiting with the limiting slide rail 13 to prevent the mattress 10 from disengaging from the middle plate 1; the diameter of the active bevel gear 12 is larger than the diameter of the driven bevel gear 11, the active bevel gear 12 rotates a smaller angle, and the driven bevel gear 11 drives the cloth rolling shaft 9 to roll a larger angle, preventing the mattress 10 from driving the patient to move an insufficient distance; the setting of the slide 28 makes the movement of the driving frame 7 more stable.

[0041] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
