The rotating assembly is used for driving the stretcher rotating baffle plate 1 to rotate so as to realize the rapid disassembly and assembly of the stretcher 6. The rotating assembly comprises a stretcher rotating shaft 5 and a rotating handle 8. Through holes are formed in the long vertical plate and the short vertical plate of the stretcher supporting frame 7, the stretcher rotating shaft 5 penetrates through the stretcher supporting frame 7 and is rotatably arranged on the stretcher supporting frame 7, and two ends of the stretcher rotating shaft 5 extend out of the stretcher supporting frame 7. The rotating handle 8 is fixedly arranged at one end of the stretcher rotating shaft 5 through a screw. The stretcher rotating baffle plate 1 is fixedly arranged at the other end of the stretcher rotating shaft 5 through screws.

The inner side surface of the stretcher rotating baffle plate 1 is fixedly provided with a clamping friction plate 2 through screws, the clamping friction plate 2 is in contact with the stretcher 6, and the inner side surface of the clamping friction plate 2 is a friction surface which can increase the friction force between the inner side surface and the side wall of the stretcher 6.

A friction washer 4 and a silica gel washer 3 are also sleeved on the stretcher rotating shaft 5 between the stretcher rotating baffle 1 and the stretcher supporting frame 7. The friction washer 4 is in contact with the stretcher support frame 7. The silica gel washer 3 is fixedly arranged between the friction washer 4 and the stretcher rotation baffle plate 1.

The stretcher rotating baffle plate 1 is provided with a limiting positioning pin 10 used for limiting the rotating angle of the rotating assembly, and the inner side surface of the stretcher rotating baffle plate 1 is provided with a groove matched with the limiting positioning pin 10.

The upper part of the stretcher supporting frame 7 is connected with a stretcher adapter plate 14 fixedly arranged on the main machine through a locking component.

The locking component comprises an unlocking handle 9 arranged on the stretcher supporting frame 7, a plurality of unlocking handle clamping hooks 9a are arranged on the unlocking handle 9, and a stretcher transfer plate bayonet 14a matched with the unlocking handle clamping hooks 9a is arranged on the stretcher transfer plate 14.

Specifically, a sliding groove is formed in the top end of the stretcher support frame 7, the unlocking handle 9 is arranged in the sliding groove in a sliding mode, one end of the unlocking handle extends out of the stretcher support frame 7, a guide post 13 which is arranged in a tapered mode and enables the unlocking handle 9 to penetrate through is fixedly arranged on the top end face of the stretcher support frame 7, the unlocking handle clamping hook 9a penetrates through the guide post 13, and a conical shell matched with the guide post 13 is arranged on the stretcher transfer plate 14. One end of the unlocking handle 9 is provided with a convex column positioned inside the guide column 13, and a compression spring 11 with one end in contact with the unlocking handle 9 and the other end in contact with the inner wall of the guide column 13 is sleeved on the convex column.

A groove is formed in the top end face of the top plate of the stretcher supporting frame 7, a stretcher supporting frame pad 12 is further arranged between the stretcher supporting frame 7 and the stretcher adapter plate 14, and the stretcher supporting frame pad 12 is embedded in the groove.

The assembly process of the present invention is as follows.

The clamping friction plate 2 and the stretcher rotating baffle 1 are fixed together through screws to form a clamping friction plate assembly. Then the rotating handle 8 is fixed with the stretcher rotating shaft 5 through screws and then inserted into the through hole of the stretcher supporting frame 7, the friction washer 4, the silica gel washer 3 and the clamping friction plate component are sequentially assembled on the other side of the stretcher rotating shaft 5, and finally the stretcher rotating baffle plate 1 and the stretcher rotating shaft 5 are fixed through screws.

The unlocking handle 9 is placed in the sliding groove of the stretcher support frame 7, then the stretcher support pad 12 is attached to the surface of the stretcher support frame 7, and the guide post 13 and the stretcher support frame 7 are fixed together by passing through a through hole of the stretcher support frame 7 through a screw.

When the stretcher transfer plate is practically used, the stretcher transfer plate 14 is fixed in the host machine, when the host machine is put down, the inner conical hole of the conical shell on the stretcher transfer plate 14 is attached to the outer conical surface of the guide column 13 under the action of the guide column 13, meanwhile, under the action of gravity, the stretcher transfer plate 14 drives the unlocking handle 9 to move in the falling process, and finally, the stretcher transfer plate bayonet 14a and the unlocking handle clamping hook 9a are mutually buckled to form a clamping structure, so that the stretcher transfer plate 14 can be reliably fixed in the fixing device. When the host needs to be lifted from the fixing device, the handle of the unlocking handle 9 is pressed to drive the unlocking handle 9 to integrally translate, so that the unlocking handle hook 9a is separated from the stretcher transfer plate bayonet 14a, the fixing device is unlocked at the moment, and the host can be easily lifted.

The rotary handle 8, the stretcher rotary baffle 1 and the clamping friction plate 2 are linked under the action of the stretcher rotary shaft. As shown in fig. 1, when the rotating handle 8 is in a horizontal state, the clamping friction plate 2 and the stretcher rotating baffle plate 1 are in a vertical state, and at the moment, the clamping friction plate 2 tightly presses the stretcher 6 in the notch of the stretcher supporting frame 7, so that the fixing device and the stretcher are reliably connected.

When the fixing device needs to be taken down to separate the stretcher supporting frame 7 from the stretcher 6, the rotating handle 8 only needs to be rotated by 90 degrees, and the rotating handle is in a vertical state. When the rotating handle 8 is about to rotate 90 degrees, the rotating handle 8 drives the stretcher rotating shaft 5, the stretcher rotating baffle plate 1 and the clamping friction plate 2 to rotate 90 degrees, at the moment, the stretcher rotating baffle plate 1 and the clamping friction plate 2 do not clamp the stretcher 6 any more, and the stretcher 6 can be directly taken out.

The limiting positioning pin 10 is fixed on the stretcher supporting frame 7, meanwhile, a groove matched with the limiting positioning pin 10 is machined in the inner surface of the stretcher rotating baffle plate 1, the limiting positioning pin 10 can limit the rotating angle of the rotating handle 8, the risk that the stretcher rotating baffle plate is stressed unevenly or the stretcher falls off due to the fact that the rotating amplitude of the stretcher rotating baffle plate 1 is not proper is avoided, and meanwhile, the time for installing and disassembling the fixing device is saved.

When fixing stretcher rotating baffle 1 and stretcher pivot 5 with the screw, silica gel packing ring 3 is compressed under the effect of pressure, can increase the rotation of rotating handle 8 this moment and feel, and friction packing ring 4 has wear-resisting nylon material to process simultaneously and forms, ensures the reliability after fixing device uses for a long time.
