Referring to fig. 2 and 3, the invention can realize that a patient can turn over freely without twisting the suspended joint when lying in bed and suspending limbs through the structure. That is, when the user turns over, the limit plate 104 limits the bed board 101 transversely, and the support block 303 slides along the annular guide rail 301 along with the downward pressing of the bed board 101 due to the low gravity of the user, so as to change the fluctuation of the bed board 101 and the fluctuation of the bed sheet 102, thereby turning over the user, and the orientation angle of the support frame 200 is changed due to the influence of the ring shape of the annular guide rail 301, thereby fitting the orientation of the human body, so that the suspended joint cannot twist or even sprain due to the turning over.

Referring to fig. 1 and 11, the locking frame 500 of the present invention can press the bed plate 101 through the pressing plate 503 when the user does not need to turn over, so that the bed plate 101 cannot move up and down, thereby keeping the plane formed by the bed plate 101 flat and not swaying, and also lock the bed plate 101, so that the plurality of bed plates 101 cannot form a cambered surface, thereby stabilizing the plurality of bed plates 101 when feeding a patient and massaging the patient.

Wherein, the upper ends of the first column 501 and the second column 502 of the locking frame 500 can be inclined to the bed tail end of the bed board 101, so that the pressure plate 503 does not occupy too much area of the bed board 101, thereby not obstructing the patient to lie in bed.

Preferably, the number of the bed plates 101 is less than or equal to the number of the supporting blocks 303.

The present invention can make the supporting blocks 303 more easily move along the circular guide rail 301 in a rotating manner through more supporting blocks 303, and more smoothly support the bed plate 101.

Preferably, referring to fig. 4 and 5, a weight block 311 is embedded in the lower portion of the supporting block 303, the weight block 311 is in a tumbler shape, the weight of the lower portion of the weight block 311 is greater than the weight of the upper portion of the weight block 311, a clamping rod 312 is disposed on the lower portion of the weight block 311, two ends of the clamping rod 312 are clamped with the two arc-shaped guide rails 313 and move along the two arc-shaped guide rails 313, the two arc-shaped guide rails 313 are in contact with one side of the rolling ball 302, which is far away from the center of the circular guide rail 301, one side of the rolling ball 302, which is close to the center of the circular guide rail 301, is in contact with the surface of the arc-shaped guide rail 313, which is close to the center of the circular guide rail, an.

The invention makes the supporting block 303 keep the vertical state through the balancing weight 311 so as to support the bed board 101, and guides the movement of the whole supporting block 303 by taking the balancing weight 311 as a movement point, so that the movement of the supporting block 303 is more stable. In addition, the arc-shaped guide rail 313 for guiding the weight 311 can support the ball 302, so that it can be longitudinally and transversely limited for the ball 302, preventing the ball 302 from swinging.

The third rod 240 is kept away from the base 210 by the torsion spring 204, and the third rod 240 is kept in a downward-pulling state by the winding machine 250 and the pull rope 203. When the lifting device is used, when the third rod 240 needs to be lifted, the third rod 240 can be lifted through the torsion spring 204 only by closing the winch 250; when the third rod 240 needs to be dropped, the third rod 240 can be dropped through the second rod 230 only by continuously pulling the pull rope 203 through the winch 250.

The invention can realize that the whole supporting frame 200 keeps the orientation posture along with the independent movement of the single bed board 101 through the base 210 fixed on the single bed board 101 so as to be convenient for the change of the angle when the human body turns over, and can keep as flat as possible when the supporting frame is retracted through the connection of a plurality of rod bodies.
