The lifting push rod 14 is hinged on the bed chassis 1, the movable end of the lifting push rod 14 is hinged on one of the supports 12, when the lifting push rod 14 is retracted, the support 12 can be driven to rotate, and the other support 12 is rotated at the same angle through the connecting rod 13, so that the height of the first intermediate bed frame 41 is changed, and the user is provided with the convenient bed surface height adjusting function, thereby meeting the needs of patients with different heights.

[0045] In order to facilitate the patient to get up from the upper body, the utility model designs the turnover device including turnover push rod 10 and first vertical rod 101, wherein, first vertical rod 101 is fixed at the bottom of first intermediate bed frame 41, and both ends of turnover push rod 10 are hinged with second intermediate bed frame 51 and first vertical rod 101 respectively. Through the accurate retraction of the turnover push rod 10, the flexible turnover of the second intermediate bed frame 51 relative to the first intermediate bed frame 41 is realized, and the user is provided with more diversified lying posture selection. When using the turnover function, in order to make the two second side bed frames 52 follow the second intermediate bed frame 51 to turn over, the utility model designs a limiting mechanism, the limiting mechanism includes a first limiting sleeve 6 fixed on the second intermediate bed frame 51, a first guide sleeve 7 fixed on the second side bed frame 52, a first limiting piece 71 slidingly installed on the first guide sleeve 7, a first limiting rod 72 fixed on the side of the first limiting piece 71 away from the first limiting sleeve 6, a limiting plate 73 fixed on the second side bed frame 52 and a first spring 74 sleeved on the first limiting rod 72 between the first limiting piece 71 and the limiting plate 73, the end of the first limiting piece 71 is inserted into the first limiting sleeve 6 through the spring force of the first spring 74, so that the second side bed frame 52 is fixed with the second intermediate bed frame 51 and can follow the second intermediate bed frame 51 to turn over.

[0046] Embodiment two:

[0047] On the basis of embodiment one, considering that it is more laborious for part of patients to change from the lying posture to the lateral lying posture, therefore, the utility model designs a side pushing device, so that the first side bed frame 42 and the second side bed frame 52 can be turned over, thereby pushing the half body of the patient and assisting in turning around.

[0048] As Figure 4 and Figure 5As shown, the side pushing device comprises the second vertical rod 11 fixed on the first intermediate bed frame 41 and the side pushing rod 111 hinged on the second vertical rod 11, the movable end of the side pushing rod 111 is hinged on the first side bed frame 42, and the telescopic adjustment of the side pushing rod 111 enables the angle between the first side bed frame 42 and the first intermediate bed frame 41 to be freely adjusted, so that the half body of the patient can be pushed, and the patient can change the sleeping posture.

[0049] Embodiment three:

[0050] On the basis of the above-mentioned embodiments, the utility model further designs linkage mechanism, including fixed in first side bed frame 42's second limit cover 8, fixed in second side bed frame 52's second guide cover 81, sliding installation in second guide cover 81's second limit piece 82, fixed in second limit piece 82's second limit rod 83, and fixed in second side bed frame 52's linkage push rod 9, the movable end of linkage push rod 9 is fixed with drive plate 91, drive plate 91 is fixed with the rod sleeve 92 that sets up on second limit rod 83, the second spring 93 of second limit rod 83 is set up between the rod sleeve 92 and second limit piece 82, and the limit head 94 of second limit rod 83 is fixed on the side away from second spring 93 of rod sleeve 92.

[0051] In this way, when the linkage push rod 9 is telescopic, the second limit rod 83 can be driven to move through the rod sleeve 92, so as to control the second limit piece 82 to insert into or separate from the second limit cover 8, and realize the connection or disconnection between the second side bed frame 52 and the first side bed frame 42.

[0052] As shown in Figure 4 and Figure 5 , the first limit rod 72 is also fixed with a push rod 95. The drive plate 91 is provided with a drive slope 96, when the drive plate 91 moves to the position where the drive slope 96 abuts against the push rod 95, the drive slope 96 can push the push rod 95 to move, compress the first spring 74, and pull out the first limit piece 71 from the first limit cover 6, so that the second side bed frame 52 can be side pushed together with the first side bed frame 42.

[0053] In use, the height of the bed surface can be easily adjusted by operating the lifting push rod 14 in the lifting mechanism. The turnover device and the side pushing device are used to adjust the turnover angle and the side lying angle of the bed surface respectively, so as to provide a more comfortable rehabilitation experience for the user.
