The stretcher comprises a stretcher main body, arm rests and supporting legs, wherein the arm rests are arranged on the stretcher main body; the supporting legs are used for supporting the stretcher main body; the supporting legs with adjustable height are adopted; a rotating wheel is arranged at the bottom end of each supporting leg; each supporting leg comprises an upper leg and a lower leg, wherein the lower leg is arranged in the upper leg and can move up and down; a positioning device is fixed at the bottom of the upper leg; a hole matched with the lower leg is reserved on the positioning device; the lower leg passes through the hole on the positioning device to be arranged in the upper leg; a plurality of locking grooves are reserved on the upper leg from the top to the bottom; a sleeve ring-shaped brake pad is sleeved on the lower leg; the sleeve ring-shaped brake pad passes through the positioning device to connect a height adjusting plate; and a hand-operated leg folding device which is used for folding each supporting leg and placing the folded supporting leg below the stretcher main body horizontally is arranged between each supporting leg and the stretcher main body. The stretcher with the height-adjustable supporting legs has the advantages that: the structure is simple; the stretcher is convenient to operate; and the height of the supporting legs can be adjusted independently and rapidly.

Description

technical field [0001] The invention relates to the technical field of medical rescue equipment, in particular to a stretcher with adjustable support legs. Background technique [0002] The stretcher trolleys currently on the market cannot meet the needs of the field where the ground is uneven or the height needs to be adjusted. At the same time, the existing stretcher trolley has a large bottom, which is inconvenient to move, and the legs cannot be folded away, so the stretcher trolley needs to occupy a large space. There are also hand-operated lifting stretcher vehicles on the market, but all its supporting legs are adjusted at the same time, and the independent adjustment of the four legs cannot be realized. Moreover, its structure is more complicated, the cost is expensive, and it is only suitable for indoor flat ground, which cannot meet the needs of the field. need for assistance.
