The invention discloses a self-locking type lifting hook. The self-locking type lifting hook comprises a fixed hook seat and a movable hook body, a connecting part used for being connected with an external rope is arranged at the top of the fixed hook seat, a through hole is formed in the lower part of the fixed hook seat, the movable hook body penetrates through the through hole, and is rotationally connected with the fixed hook seat through a rotating shaft at the through hole; the movable hook body is divided into a hook-shaped part and a rod part by taking the position where the rotating shaft is located as a boundary point, the rod part and the hook-shaped part are arranged on two opposite sides of the fixed hook seat, the weight of the hook-shaped part is smaller than the weight of the rod part, the distance from the end part of the end, far away from the rotating shaft, of the rod part to the rotating shaft is larger than the distance from the end part of the upper end of the through hole to the rotating shaft, the rod part is provided with a magnet at the end which is far away from the rotating shaft, the magnet is installed on the side surface of the side, facing the fixedhook seat connecting part, of the rod part, the magnet and a hook tip of the hook-shaped part are arranged on the two opposite sides of the movable hook body correspondingly, and a suction part is arranged on the side face, facing the side where the magnet located, of the fixed hook seat. According to the self-locking type lifting hook, the unhooking condition of the rope can be effectively prevented, operation of a worker is facilitated, and automatic unhooking can be realized after lifting is finished.
