[0035] When the patient needs to maintain a semi-recumbent position, refer to Figure 2 The first push rod 31 extends out, driving the back support frame 12 to rotate upward relative to the main frame 11. The angle between the back support frame 12 and the main frame 11 can be changed according to the patient's needs, so that the patient is in a comfortable lying position, and the support rod 2 can be telescopically adjusted so that the support rod 2 is supported on the ground.

[0036] When the patient needs to move in a wheelchair, the wheelchair bed transforms into a wheelchair state. Figure 4 and Figure 5 , the first push rod 31 extends, driving the back support frame 12 to continue to rotate upward relative to the main frame 11, and rotates to a wheelchair back position that is comfortable for the patient. The second push rod 32 retracts, driving the leg support frame 13 to rotate downward relative to the main frame 11, and rotates to a position where the patient's legs can be placed comfortably. The third push rod 33 extends, driving the foot support frame 14 to rotate upward relative to the leg support frame 13, and rotates to a position where the patient's feet can be placed comfortably; rotate the support rod 2, rotate it until the support rod 2 can be stuck in the position of the first buckle 121, and fix the support rod 2 for storage.

[0037] When the patient does not need the guardrail 5 temporarily, refer to Figure 2 and Figure 3 , so that the pin 51 of the guardrail 5 is disengaged from the rotating rod 123, and the guardrail 5 slides downward in the rotating rod 123 until the upper part of the guardrail 5 abuts against the top surface of the rotating rod 123. When the guardrail 5 needs to be used, it only needs to be lifted up to allow the pin 51 to be inserted into the rotating rod 123 to fix the position of the guardrail 5.

[0038] When the guardrail 5 is to be stored, the latch 51 of the guardrail 5 is disengaged from the rotating rod 123, so that the guardrail 5 can slide relative to the rotating rod 123, and the rotating rod 123 is rotated to drive the guardrail 5 to rotate to the storage position. The guardrail 5 slides to a position where one side of the guardrail 5 can be clamped in the second buckle 122 to fix the position of the guardrail 5. At this time, the guardrail 5 and the back support frame 12 are arranged in parallel.
