Summary:The utility model relates to a slowly lowering adjustable reciprocating simple life-saving device for high-rise buildings. A brake effect is carried out on a rotary shaft wound with cables by utilizing a braking disc for providing the function of slowly lowering escape; simultaneously, the braking disc can adjust the tightness of brake according to the body weight of the human body or the slowly lowering speed. The rotary shaft is divided into two sections for winding cables, and winding directions in the two sections are opposite. When the cable in one section is lowered, the cable in the other section can be automatically collected and wound, and therefore, the slowly lowering adjustable reciprocating simple life-saving device for high-rise buildings having the function of reciprocating use. The utility model has the advantages of simple structure, low cost, slowly lowering escape without electricity or other energy sources, adjustable tightness of brake, the function of reciprocating use, etc.
