At this time, the inner wall of the ring will squeeze the outside of the fan-shaped plate, causing the fan-shaped plate to move toward the axis of the fixing column. At the same time, the first spring is compressed. When the ring is completely moved down to the outside of the fixing column and no longer contacts the side of the fan-shaped plate, the first spring will drive the fan-shaped plate to reset, causing the bottom end of the fan-shaped plate to limit the ring.

When the direction of the ring in the reversing assembly needs to be adjusted, the pull plate is manually pulled outward, and the pull plate will pull the second spring to extend and cause the insertion rod to disengage from the directional groove. At this time, the rotation restriction between the directional seat and the rotating sleeve is released, and the rotating sleeve can be rotated to synchronously rotate the ring. After the rotating sleeve is rotated 180 degrees, the pull plate is released, and the second spring will contract and cause the insertion rod to be stuck in another symmetrically opened directional groove, thereby re-locking the rotation of the rotating sleeve.

[0029] like Figures 1 to 3 As shown, a guardrail 1 is provided on one side of the base plate 3, and the power assembly includes a protective cover 17 connected on both sides of the guardrail 1. A rotating rod 7 is provided on the protective cover 17 close to one side of the base plate 3 for rotation. The two ends of the rotating rod 7 are coaxially connected with a pulley 6 and a lead screw 8, respectively. The lead screw 8 is arranged in a slide groove 16, and the free end of the lead screw 8 is coaxially connected to a limiting plate 10, and the lead screw 8 is passed through the movable plate 15.

[0030] like Figures 1 to 3 As shown, a motor 9 is provided at either end of the base plate 3, the output shaft of the motor 9 is coaxially connected to the free end of the adjacent pulley 6, the two pulleys 6 are connected by a synchronous belt 5, and the pulley 6 and the synchronous belt 5 are jointly arranged in the cavity at the bottom of the protective cover 17 and the guardrail 1.

[0031] like Figure 1 and Figure 2 As shown, a headrest 4 is fixedly connected to the bed sheet 2 , and the setting direction of the headrest 4 relative to the base plate 3 is opposite to the motor 9 .

[0032] like Figure 4 and Figure 5 As shown, the fixing assembly includes a fixing column 28 fixedly connected to the top of the connecting block 26, and three fan-shaped plates 24 are slidably clamped on the fixing column 28. The top radius of the fan-shaped plate 24 is smaller than the bottom radius thereof.

[0035] The fixing assembly can stably connect the bed sheet 2 with the collar 30. When the collar 30 needs to be sleeved to the outside of the fixing column 28 in the fixing assembly, the fixing column 28 is first moved to the bottom of the collar 30, and then the connecting block 26 is lifted upward. At this time, the inner wall of the collar 30 will squeeze the outside of the fan-shaped plate 24, so that the fan-shaped plate 24 moves toward the axis of the fixing column 28.

When the collar 30 is completely moved down to the outside of the fixing column 28 and no longer contacts the side of the fan-shaped plate 24, the first spring 25 will drive the fan-shaped plate 24 to reset, so that the bottom end of the fan-shaped plate 24 limits the collar 30.

[0036] When the ring 30 needs to be disconnected from the current fixed column 28, the control panel 22 needs to be manually lifted, and the pull rope 23 connected to the bottom end of the control panel 22 will pull the fan-shaped plate 24 connected to its free end inward, so that the fan-shaped plate 24 moves inward to the limit position, and then the fixed column 28 is moved down to release the connection between the ring 30 and the fixed column 28.

[0037] like Figure 4 and Figure 5 As shown, the reversing assembly includes a directional seat 35 connected to the bottom end of the connecting arm 34, and a rotating sleeve 31 is rotatably clamped on the outer side of the directional seat 35.

[0040] The reversing assembly can prevent the device components from causing excessive impact on the patient when the transfer assembly pulls the bed sheet 2 and the patient. When the direction of the ring 30 in the reversing assembly needs to be adjusted, the pull plate is manually pulled outward, and the pull plate will pull the second spring 32 to extend and make the insertion rod 37 disengage from the orientation groove 36. At this time, the rotation restriction between the orientation seat 35 and the rotating sleeve 31 is released, and the rotating sleeve 31 can be rotated synchronously to rotate the ring 30. After rotating the rotating sleeve 31 180 degrees, release the pull plate, the second spring 32 will shrink and make the insertion rod 37 fit into another symmetrically opened orientation groove 36, and the rotating sleeve 31 will be rotationally locked again.

[0041] The specific usage and function of this embodiment are as follows:

[0042] The transfer assembly provided in the present invention can transfer the patient bidirectionally without the need to redeploy the device as a whole. At the same time, the transfer process can be completed automatically without the assistance of external force from the operator, which reduces the difficulty of operation and significantly improves the transfer efficiency. The device is fixed as a whole on any mobile platform with adjustable height. Before the transfer begins, the height of the mobile platform is first adjusted so that the upper surface of the substrate 3 is flush with the upper surface of the diagnosis and treatment bed to which the patient is to be transferred. At the same time, the mobile platform is moved to one side of the diagnosis and treatment bed and is tightly attached to any side of the diagnosis and treatment bed, and then the transfer assembly can be used to start the transfer;

[0043] Before using the transfer assembly to transfer the patient from the top of the base plate 3 to the diagnosis and treatment bed, the two rings 30 need to be sleeved on the two fixed assemblies on the side of the base plate 3 where the guardrail 1 is not set, and then the motor 9 is started. The motor 9 will drive the pulley 6 coaxially connected thereto to rotate. Since the two pulleys 6 are connected by a synchronous belt 5, the lead screw 8 coaxially connected to the two pulleys 6 through the rotating rod 7 will also rotate synchronously, and the movable plate 15 passed through the lead screw 8 will also slide in the slide groove 16 opened at both ends of the base plate 3. During the movement of the two movable plates 15, the sliding rod 21 clamped by the magnetic block 19 on them will be driven to move synchronously. The connecting arm 34 fixedly connected at one end of the sliding rod 21 will drive the ring 30 to move through the reversing assembly, and the two fixed assemblies on which the ring 30 is sleeved will pull the bed sheet 2 to translate until the bed sheet 2 and the headrest 4 drive the patient to move completely to the diagnosis and treatment bed. At this time, the patient's transfer process from the base plate 3 to the diagnosis and treatment bed is completed;

[0044] After the diagnosis and treatment is completed, when the transfer component is needed to transfer the patient from the diagnosis and treatment bed to the top of the base plate 3, the connection between the ring 30 and the current fixed component must be released first, and the direction of the transfer component must be adjusted at the same time. Then, the electromagnetic plate 12 set at one end of the bracket 13 is energized, and the electromagnetic plate 12 will suck up the magnetic block 19 slidingly stuck in the connecting groove 18. At this time, the movable seat 14 releases the movement restriction of the slide bar 21, and the two slide bars 21 are manually pushed to align the second limit groove 29 opened on the slide bar 21 with the connecting groove 18, and then the electromagnetic plate 12 is powered off. The magnetic block 19 will reset under the action of weight and be stuck in the second limit groove 29 to restrict the movement of the slide bar 21 again. At this time, the ring 30 is connected to the two fixed components on the side of the sheet 2 close to the base plate 3, and the drive motor 9 is reversed. Similarly, it can be known that the two movable seats 14 will reset and pull the sheet 2 and the patient back to the base plate 3. After completing the transfer of the patient from the diagnosis and treatment bed to the base plate 3, the slide bar 21 is manually reset to carry out the next transfer.

[0045] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
