[0061] Embodiment 3: In some embodiments, Figure 1-Figure 10 As shown, as a preferred embodiment of the present invention, the following steps are included:

[0062] Step 1: When a critically ill patient needs to be transferred, the mobile nursing frame body 1 is moved to the position of the patient's bed;

[0063] Step 2: At this time, the two groups of seat assemblies 41 are in the open mode. When the height of the adjustable seat assembly 4 is adjusted, the lifting end of the air pressure lifter 21 drives the lifting frame 22 to lift, and the lifting frame 22 drives the outer rod 31 and the inner slide rod 32 to lift. At this time, the slide column 36 is located in the lower horizontal groove of the guide groove 35, and the slide column 36 drives the lower horizontal groove of the guide groove 35 to lift. At the same time, the slide column 36 slides along the straight groove 37, and the movement of the rotating sleeve 34 drives the seat assembly 41 to move;

[0064] Step 3, when the two groups of seat assemblies 41 are closed, the armrest frame 411 is rotated, and the armrest frame 411 drives the rotating sleeve 34 to rotate, and the slide column 36 is drawn out from the lower horizontal groove of the guide groove 35 provided on the rotating sleeve 34, and the oblique groove section of the guide groove 35 slides along the slide column 36. At this time, the rotating sleeve 34 rotates and slides downward on the outer wall of the outer sleeve rod 33, and the rotating sleeve 34 drives the seat assembly 41 to move downward as a whole. When the upper horizontal groove of the guide groove 35 matches the slide column 36, the spring bolt 428 is plugged into the polygonal slot 434, and the two back plates 413 are plugged in through the plug block and the slot, so that the left back plate 413 limits the right back plate 413;

[0065] The two sets of back plates 413 and seat plates 412 complete the merging mode;

[0066] When the present invention is used, since the two seat boards 412 move downward during the joining process, the patient does not need to lift his hips significantly to avoid the two seat boards 412 , and the downward movement of the seat boards 412 can squeeze the bed to deform, thereby facilitating the transfer of the patient from the bed to the seat boards 412 .

[0067] Step 4, when it is necessary to adjust the angles of the two back plates 413 when the two groups of seat assemblies 41 are combined, the connection cover 421 is pushed, and the connection cover 421 drives the rotation shaft 422 to slide along the left connection block 415, and the connection cover 421 compresses the spring 2 424. At this time, the tooth groove slope 1 426 and the tooth groove slope 2 427 are disengaged, and the connection cover 421 is rotated, and the connection cover 421 drives the rotation shaft 1 422, the right connecting rod 414, and the back plate 413 to rotate, and the rotation shaft 422 drives the spring bolt 428 to rotate, and the spring bolt 428 drives the rotation shaft 2 432 with a polygonal slot 434 to rotate, and the rotation shaft 432 drives the connection rod 2 431 to rotate, and the volute spring 433 is elastically deformed, and the connection rod 2 431 drives the left connecting rod 414 and the back plate 413 to rotate;

[0068] The connection cover 1 421 is reset, so that the tooth groove inclined surface 1 426 and the tooth groove inclined surface 2 427 are re-engaged, and the rotating shaft 1 422, the spring bolt 428, and the rotating shaft 2 432 are locked synchronously.

[0069] When the present invention is used, when the slide post 36 is located in the upper horizontal groove or the lower horizontal groove of the guide groove 35, due to the spring force of spring 1 38, the slide post 36 is locked against the inner wall of the horizontal groove or the lower horizontal groove of the guide groove 35, thereby realizing the self-locking of the rotating sleeve 34 in the merging mode or the opening mode of the two groups of seat components 41.

[0070] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
