The invention discloses a lifting hook for hollow blocks and relates to the technical field of hollow four-leg blocks. The lifting hook comprises a lifting ring and a clamping rod. The clamping rod isused for clamping hollow bricks and further comprises an internal expansion mechanism. The internal expansion mechanism is rotatably connected with the lifting ring, the clamping rod is movably connected with the internal expansion mechanism and located on the outer side of the internal expansion mechanism, and the internal expansion mechanism is used for pushing the position of the clamping rodoutward. Assembly clamping plates are fixed to the two sides of the bottom end of the lifting ring and connected with the internal expansion mechanism through first rotation pins, a clamping part comprises a pull rod and a lower movable arm, and the pull rod is fixed to one side of the lower movable arm. Through a novel structural design of the lifting hook, the lifting hook well solves the lifting problem of dead-corner hollow cubes, the lifting ring does not need to be embedded in the cube bodies, a band is not needed either, only one worker is required to hang the lifting hook, and the lifting hook is easy to use, safe and efficient, greatly lowers the lifting cost, and improves the production efficiency.
