DETAILED DESCRIPTION

[0027] The embodiment of the present invention provides a transfer structure for transferring a surgical patient to a hospital bed, such as Figure 1-8As shown, it is arranged on the transport vehicle 1 and the bed 2, or it can be the transport vehicle 1 and the operating table, and the transport vehicle 1 serves as the intermediate transport carrier. The basic structure of the transport vehicle 1 and the bed 2 is consistent with the existing ones, and the transport structure is installed on the existing transport vehicle 1 and the bed 2. The transport structure includes a bearing plate 3, two sets of sliding shafts A4, and two sets of sliding shafts B5. The bearing plate 3 serves as a carrier for the patient. The bearing plate 3 is consistent with the structure and material of the existing transport bed support body, and a cushion can be arranged on the bearing plate 3. The sliding shaft A4 and the sliding shaft B5 have the same structure and size. The two sets of sliding shafts A4 are arranged at the head and tail ends of the transport vehicle 1, and the two sets of sliding shafts B5 are arranged at the head and tail ends of the bed 2. The head and tail ends of the bearing plate 3 are respectively provided with sliding sleeves 6 arranged outside the sliding shaft A4, and the sliding shafts A4 and B5 are axially provided with mutually connected transverse slideways 12, and the inner side of the sliding sleeve 6 is provided with a slider 14 slidingly adapted in the transverse slideway 12.

[0028] When the transverse slideways 12 on the sliding shaft A4 and the sliding shaft B5 are connected to each other, the sliding sleeve 6 can slide axially between the sliding shaft A4 and the sliding shaft B5.

[0029] like Figure 1-3 As shown, the transverse slide 12 is provided with positioning slides 13 extending circumferentially along the periphery of the slide shaft at axially equal intervals. When the slide shaft rotates circumferentially, the slider 14 can enter the positioning slide 13. When the slider 14 enters the positioning slide 13, the sleeve 6 cannot slide axially on the slide shaft.

[0030] Positioning grooves 11 are provided at equal intervals in the axial direction on the sliding shaft A4 and the sliding shaft B5. The plurality of positioning grooves 11 correspond to the plurality of positioning slideways 13 in the axial direction. A positioning assembly is provided in the sliding sleeve 6. When the slider 14 slides into the positioning slideway 13 and is located at the outer end of the positioning slideway 13, the positioning assembly is positioned in the positioning groove 11. When the slider 14 is located in the transverse slideway 12, the positioning assembly is separated from the positioning groove 11. The positioning assembly and the positioning slideway 13 can form a double positioning for the sliding sleeve 6 to prevent the sliding sleeve 6 from axial sliding during transportation. It can also limit the sliding shaft from rotating without human operation.

[0031] Specifically, Figure 5 As shown, the positioning assembly includes two groups of positioning plates 22 and springs 23. A receiving cavity 21 is provided at the top of the sliding sleeve 6. The positioning plate 22 is bent, and the angle at the bending part of the positioning plate 22 is between 90° and 135°. One end of the positioning plate 22 is hinged in the receiving cavity 21, and the other end corresponds to the positioning groove 11. The back of the positioning plate 22 is connected to the top of the receiving cavity 21 through the spring 23. The two groups of positioning plates 22 are arranged symmetrically. When the bent sections of the two groups of positioning plates 22 are stuck in the positioning groove 11, the bent parts of the two groups of positioning plates 22 are stuck on the top angles on both sides of the positioning groove 11. At this time, the slider 14 is located at the outermost end of the positioning slide 13.

[0032] like Figure 2-3 As shown, the connecting ends of the sliding shaft A4 and the sliding shaft B5 are provided with connecting components, and the connecting components include two groups of clamping blocks 16 and clamping block annular grooves 19. The ends of the sliding shaft A4 and the sliding shaft B5 are provided with a group of clamping blocks 16 and clamping block annular grooves 19. The clamping blocks 16 and the clamping block annular grooves 19 are 180° apart in the circumferential direction. The ends of the clamping block annular grooves 19 are provided with sockets 18 for axial insertion of the clamping blocks 16. The clamping blocks 16 on the sliding shaft A4 and the sliding shaft B5 can slide in the circumferential direction in the clamping block annular grooves 19 on the sliding shaft A4 and the sliding shaft B5.

[0033] When the block 16 of the sliding shaft A4 is inserted into the socket 18 of the sliding shaft B5 , the block 16 of the sliding shaft B5 is inserted into the socket 18 of the sliding shaft A4 .

[0034] Only when the block 16 of the slide shaft A4 rotates to the limit angle in the block ring groove 19 of the slide shaft B5, the transverse slideway 12 of the slide shaft A4 corresponds to the transverse slideway 12 of the slide shaft B5.

[0035] In order to prevent the block 16 from being separated from the block annular groove 19, a limit block 17 is provided at the end of the block 16. The inner and outer diameters of the limit block 17 are larger than those of the block 16. The width of the limit block 17 is consistent with that of the block 16. The limit block 17 can be axially inserted into the socket 18. The inner end of the block annular groove 19 is provided with a limit ring groove 20 for the limit block 17 to slide in an annular direction. The annular length of the limit ring groove 20 is consistent with that of the block annular groove 19. When the limit block 17 is inserted into the bottom from the socket 18, the limit block 17 can slide in an annular direction in the limit ring groove 20.

[0036] A handle 24 is provided on the top of the sliding sleeve 6. The handle 24 is used to assist in moving the sliding sleeve 6, thereby moving the carrying plate 3.

[0037] The transfer vehicle 1 and the hospital bed 2 are both provided with height adjustment components for adjusting the heights of the two sets of sliding shafts B5 and the two sets of sliding shafts A4.

[0038] like Figure 1 As shown, the height adjustment assembly includes a support bar 7, a guide rod 9, and an adjustment screw 10. Two slide shafts B5 or two slide shafts A4 are pivoted on the respective support bars 7. The guide rod 9 is vertically fixed on the transfer vehicle 1 or the bed 2. The upper section passes through the support bar 7 and slides with it. The bottom of the adjustment screw 10 is pivoted on the transfer vehicle 1 or the bed 2. The upper section passes through the support bar 7 and is threadedly connected with it. The height of the support bar 7 is adjusted by rotating the adjustment screw 10. Thus, the height between the slide shaft B5 and the slide shaft A4 is adjusted to match the height of the two.

[0039] A rocking wheel 8 coaxially connected to the sliding shaft B5 or the sliding shaft A4 is provided on the support bar 7. The rocking wheel 8 is used to adjust the angle of the sliding shaft B5 or the sliding shaft A4.

[0040] Working principle:

[0041] Step 1, such as Figure 1 As shown, the transfer vehicle 1 is moved to the side of the patient bed 2 and placed side by side therewith.

[0042] Step 2: If the heights of the sliding shaft A4 and the sliding shaft B5 are inconsistent, the heights of the corresponding sliding shafts are adjusted by adjusting the screw rod 10 to make the heights of the sliding shaft A4 and the sliding shaft B5 consistent.

[0043] Step three, move the transfer vehicle 1 horizontally toward the bed 2 so that the block 16 at the end of the slide shaft A4 contacts the end of the slide shaft B5. If the block 16 does not correspond to the socket 18, rotate the slide shaft B5 so that the block 16 corresponds to the socket 18.

[0044] Step 4: Figure 4 As shown, the transfer vehicle 1 continues to be transversely moved so that the limit block 17 at the end of the block 16 penetrates into the limit ring groove 20, and then the sliding shaft A4 is rotated to rotate the block 16 to the end of the block ring groove 19. At this time, the slider 14 in the sliding sleeve 6 enters the transverse slide 12 from the positioning slide 13, and the positioning plate 22 disengages from the positioning groove 11.

[0045] Step 5: Figure 8 As shown, the carrying plate 3 or the handle 24 is moved transversely, so that the sliding sleeve 6 and the carrying plate 3 are transferred and slid onto the sliding shaft B5 of the bed 2 .

[0046] Step six, slide the sliding sleeve 6 to the corresponding positioning groove 11 , and then rotate the sliding shaft B5 to make the sliding block 14 slide into the positioning slideway 13 , and at the same time, the positioning plate 22 is stuck in the positioning groove 11 .

[0047] Step 7: Rotate the slide shaft A4 to rotate the block 16 to the socket 18 and separate from the slide shaft A4 and the slide shaft B5. The patient's transfer is completed.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
