The invention relates to an anti-disengagement mechanism and a crown block hook head using the anti-disengagement mechanism. The crown block hook head comprises a hook head body and the anti-disengagement mechanism. The hook head body comprises a hoisting part and a limiting hook. A material placement port is formed between the top end of the limiting hook and the hoisting part. The anti-disengagement mechanism is arranged at the material placement port in cooperation. A bolt hole is horizontally formed in the position, at the joint of the hoisting part and the limiting hook, of the material placement port. The anti-disengagement mechanism comprises a screw, nuts, a magnet, a short-side rod and a long-side rod. The screw is horizontally installed in the bolt hole. The two ends of the screwextend out of the bolt hole and are provided with the nuts correspondingly. The magnet is fixedly arranged on the outer side wall of the limiting hook. One end of the short-side rod fits the portion,at the material placement port of the hook head body, of the inner wall of the limiting hook, and the other ends of the short-side rod are fixed to the nuts. One end of the long-side rod is attachedby the magnet, and the other ends of the long-side rod are fixed to the nuts. The anti-disengagement mechanism is simple in structure, convenient to operate, reliable and durable in use and capable ofeffectively preventing a hanging belt from being disengaged from a hook.
