The embodiment of the invention provides a height-adjustable sliding type transfer trolley for passing a bed, which comprises the following components as shown in figure 1: a bed body 1 and a bed board 2; the bed body 1 is of a frame structure and comprises an upper frame 15 and a lower frame 16, and a telescopic rod 11 is connected between the upper frame 15 and the lower frame 16; two ends of the upper frame 15 are connected with linear guide rails 13, and the bed plate 2 is slidably connected in the linear guide rails 13; in a preferred embodiment, the width of the bed plate 2 is slightly larger than the width of the upper frame 15, and the bed plate 2 slides back and forth in the width direction.

The bed board 2 of the invention can slide on the upper frame 15 in a reciprocating way, thereby realizing the adjustment of the bed board 2 in the horizontal direction. Optionally, the telescopic rod 11 includes a hydraulic cylinder 111 and a support rod 112 connected to the hydraulic cylinder 111, and the hydraulic cylinder 111 drives the support rod 112 to move up and down to adjust the up-and-down direction of the bed plate 2.

When the bed is used, the telescopic rod 11 can be adjusted firstly, so that the bed board 2 is matched with the height of a patient, then the bed board 2 extends to the side of the patient, the patient can be placed on the bed board 2 only by one side of the patient, the patient can be conveniently transferred, and the secondary damage of the patient in the transferring process is avoided.

The edge of the upper frame 15 at one side of the bed board 2 sliding out is connected with a supporting claw 22, and the edges of two sides of the bed board 2 are connected with a guardrail 23 in a foldable manner; the supporting claws 22 can be lapped on the edge of the external bed to obtain supporting force and play a role in preventing the bed body 1 from inclining; the guardrail 23 can rotate 270 degrees around the edge of the bed plate 2, the function that the guardrail 23 can be folded is realized, and the guardrail can be erected after a patient is placed on the bed plate 2 to protect the patient. A pulley 24 is further connected to the guardrail 23 close to the side where the bed plate 2 slides out, and the vertical distance between the upper surface of the support claw 22 and the lower surface of the bed plate 2 is equal to the height of the pulley 24. The pulley 24 can reduce the friction between the bed plate 2 and the outside bed surface in the process of extending or retracting, so that the process of extending or retracting the bed plate 2 is smoother. Meanwhile, the vertical distance between the upper surface of the supporting claw 22 and the lower surface of the bed plate 2 is equal to the height of the pulley 24, so that the situation that the bed plate 2 is partially jacked up due to the arrangement of the pulley 24 can be avoided, and the flatness of the bed plate 2 is ensured.
