The patient is transferred to the bed by moving the bed board, and most of the existing beds are equipped with bed boards, one or both ends of which have a lifting function. Moving the bed board to the bed will affect the normal function of the bed. If the bed board is moved out from between the bed and the patient, multiple people are required to cooperate in pulling out the bed board and pushing the patient, which is inconvenient to use. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By running the No. 1 motor and the No. 2 motor, the bed board drives the patient to move, and the support frame also moves synchronously with the bed board, so that the patient is moved horizontally to the top of the bed, and then the baffle is flipped to a vertical state to block the patient, and the surrounding personnel can also hold the patient to prevent the patient from moving with the bed board. The No. 1 motor is reversed. At this time, the three support frames support the patient's legs, buttocks and back respectively, and play a major supporting role, so that the bed board is pulled out from under the patient, and then most of the patient's body contacts the bed, which reduces the pain of the patient when moving, thereby first moving the bed board and the patient. The patient is moved to the bed, and then the support assembly supports the patient and the bed board is moved out. After the bed board is moved out, the No. 2 motor reverses to pull out and reset the support frame. At the same time, the No. 3 motor runs to keep the pull-out plate stationary and pull out the support frame. At this time, the pull-out plate performs a supporting role to further reduce the contact area with the patient. Finally, the No. 3 motor flips to move the pull-out plate out from under the patient, so that the patient can be gently laid flat on the bed by cooperating with the pull-out assembly to reduce the pain caused to the patient by pulling out the bed board, and the transfer device can be operated by one person, making it more convenient to use.

A No. 1 screw rod 305 is connected, and one end of the two No. 1 screw rods 305 are fixedly installed with pulleys 307, and the outer movable sleeves of the two pulleys 307 are provided with transmission belts 308; a No. 2 motor 306 is fixedly installed on one side surface of a fixed ring 304, and the output end of the No. 2 motor 306 is fixedly connected to a No. 1 screw rod 305; a No. 1 threaded sleeve 303 is symmetrically fixedly installed on the lower surface of the connecting plate 302, and the No. 1 screw rod 305 passes through the adjacent No. 1 threaded sleeve 303 and is screwed together with the No. 1 threaded sleeve 303.

[0028] In this embodiment, the No. 1 motor 205 and the No. 2 motor 306 are in operation, and the No. 1 gear plate 204 and the No. 1 gear 206 drive the bed board 201 to move the patient. The No. 1 screw rod 305 is screwed together with the No. 1 threaded sleeve 303, and the two No. 1 screw rods 305 are driven by the pulley 307 and the transmission belt 308 to rotate synchronously, driving the support frame 301 to move synchronously with the bed board 201, and the patient is translated to the top of the bed. Then the baffle 402 is flipped to a vertical state to block the patient, and the surrounding personnel can also support the patient to prevent the patient from moving with the bed board 201. The No. 1 motor 205 is reversed. At this time, the three support frames 301 respectively support the patient's legs, buttocks and back, and play a main supporting role, so that the bed board 201 is pulled out from under the patient, and then most of the patient's body contacts the bed, which reduces the pain of the patient when moving.
