The invention provides a rapid disassembly type emergency lifesaving waistband. The rapid disassembly type emergency lifesaving waistband comprises a parachute cord and a metal button. The middle of the parachute cord is wound around the metal button to form a supporting core line. The initial end of an A end line is bent to form a forwards-knotted ring, the initial end of a B end line is bent to form a backwards-knotted ring, the backwards-knotted ring penetrates through the forwards-knotted ring from top to bottom and is located below the supporting core line, a forwards-knotted ring behind the A end line penetrates through the backwards-knotted ring from bottom to top and is located above the supporting core line, and a backwards-knotted ring behind the B end line penetrates through the forwards-knotted ring from top to bottom and is located below the supporting core line. The A end line and the B end line are sequentially arranged in this way from one end of the supporting core line to the other end of the supporting core line to form a waistband body. The waistband is simple in structure and convenient to weave, the effects of the waistband can be achieved, the two ends of the waistband can also be pulled in opposite directions, a long lifesaving rope can be rapidly formed, the disassembly speed is high, disassembly is convenient, and the emergency lifesaving effect can be achieved in time.
