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.
