[0006] Furthermore, the folding device includes a side panel, which is fixed on the outer wall of the stretcher body. A limiting groove is provided in the middle of the outer wall of the stretcher body. A connecting block is provided at the lower end of the guardrail, and the connecting block is located in the limiting groove. A connecting shaft is fixedly connected to the connecting block, and a worm wheel is provided at the end of the connecting shaft. A worm is rotatably provided in the side panel, and the worm is meshingly connected to the worm wheel. A hand wheel 2 is provided at the upper end of the worm. Through the rotation of the worm meshing with the worm wheel, the connecting shaft will drive the guardrail to flip over, so that the guardrail can be laid down to facilitate lifting the wounded from the side.
[0007] Preferably, the slider is snap-fitted and slides in the slot plate, that is, the slider can only slide up and down in the slot plate and cannot be detached from the slot plate.
[0008] Preferably, an anti-slip cover is provided on the handle.
[0009] Preferably, the thickness of the connecting block is equal to the inner width of the limiting groove, and the limiting groove can limit the movement of the guardrail.
[0010] The utility model adopts the above structure to achieve the following beneficial effects:
[0011] 1. The utility model realizes the walking function that the traditional stretcher does not have by arranging a lifting walking device. By lifting and lowering the wheels, the wheels can fall to the ground, and the rescuers can push the stretcher body to walk, saving physical strength.
[0012] 2. The utility model can realize the folding of the guardrail to a horizontal state by providing a folding device, so as to facilitate the wounded to be lifted down from the inner side of the stretcher body, thus saving physical strength. BRIEF DESCRIPTION OF THE DRAWINGS
