A multifunctional portable crawler stretcher

Abstract

The invention discloses a multifunctional portable caterpillar stretcher, which relates to a multifunctional caterpillar stretcher of a rescue tool. The stretcher is a pure mechanical structure, cheapand easy to popularize, simple to operate. The multifunctional portable caterpillar stretcher adopts a folding design, which reduces occupying space, is light in weight and easy to carry; Can realizestretcher form, supine form, wheelchair form polymorphism change, adapt to the demand of different occasions; Caterpillar design is adopted to accelerate the transportation speed and increase the stability in the transportation process. When the wheelchair function is realized, the upper body part, the middle body part and the lower body part form a certain angle with the support body, and the wheelchair form is realized by the support of the leg part and the foot pedal part. When the stretcher function is realized, the upper body plate part, the middle body plate part and the lower body plate part are in a horizontal position with the support body, the crawler mechanism and the folded leg part, and the foot pedal part is kept parallel to realize the stretcher form.

Description

technical field [0001] The invention relates to a portable crawler-type stretcher, in particular to a multi-functional portable crawler-type stretcher which adopts a purely mechanical structure, can realize various changes in shapes, and is suitable for different occasions. Background technique [0002] In the emergency rescue of sudden disasters (such as earthquakes, floods, fires, etc.), the timely delivery and care of the wounded is very important, and stretchers play a pivotal role. At present, there are many emergencies, and rescue missions have higher and higher requirements for the functions of rescue equipment. After major disasters such as fires and earthquakes, there will often be a large number of casualties and insufficient rescue equipment. In time, the wounded will suffer more damage. Therefore, very high requirements have been put forward for the stretcher for transporting the wounded after the on-site injury, that is, it is required to be operated quickly an...
