[0032] Working principle: First, according to the actual situation of the patient to be transported, choose whether the stretcher body 201 is in a lying state or a seat state. The stretcher body 201 is usually in a lying state. When the patient needs to lie flat, he only needs to push the second support rod 106 upwards and then close the second support rod 106 through the limit rod and the buckle outside the support shell 105 to fix the position of the second support rod 106, and then loosen the elastic rope control box 107, and pull the other second support rod 106 outward through the slider 102 to drive the elastic rope body 108 to extend. After extending to a suitable position, it is fixed through the action of the slide groove 101 and the slider 102, and then the patient can lie on the stretcher body 201. When the patient lies on the stretcher body 201, turn on the water pump 303, and the water pump 303 draws the liquid inside the constant temperature water tank 301 through the connecting water pipe 302 to dissipate the heat The tube 305 circulates on the stretcher body 201 to heat and keep the stretcher body 201 warm, providing a comfortable environment for the patient. When some patients need to maintain body temperature, the temperature of the constant temperature water tank 301 can be increased to achieve the effect. When the patient is not suitable for lying down, the stretcher body 201 needs to be deformed. First, the bolt 207 is turned to loosen the sliding clamp block 206, and then the sliding clamp block 206 is slid downward on the vertical rod 210. Under the rotation of the third hinge 205, the supporting connecting rod 204 is retracted inwardly, and the second hinge 203 is rotated at the same time to cooperate with the supporting connecting rod 204 to rotate and retract. At the same time, the first hinge 202 on the stretcher body 201 is also rotated to retract the stretcher body 201 at the foot downward. When adjusting the top, follow the same steps as above, and raise and fix the fence protection assembly 1.
