The invention discloses a press-down twist lock autorotation hanger for hoisting a container. The hanger is directly arranged on a hoisting beam of hoisting equipment, and does not need hydraulic, pneumatic or electric drive; and by using downward pressing of the hoisting equipment, a twist lock head rotates for 90 degrees, hooking or loosening of a vertex angle member of the container is finished, and the hoisting operation is realized. The press-down twist lock autorotation hanger is characterized by comprising a hanger framework, an upper mounting seat, a lower mounting seat, a return spring enclosure, a twist lock assembly, a jacking device and a signal switch. The hanger framework has a frame-shaped structure and is used for installing each member. The twist lock assembly comprises the twist lock head, a twist lock rod, a rotary pin, a rotary block, a rotary block return spring, a spring stop block, a thrust bearing, a return spring, a stop block pin, a clamping spring, a clamping steel ball and a twist lock pin. The upper mounting seat is provided with a spiral groove, the middle of the lower mounting seat is provided with a circular hole, and a square groove is processed on the upper end face of the lower mounting seat. The signal switch is used for giving twist lock state signals. The press-down twist lock autorotation hanger has simple and compact structure, reduces the manufacture and maintenance costs, and has good practical effect.
