The invention relates to the technical field of hooks, in particular to a super-heavy metal prevention hook which comprises a hook body, the hook body is composed of a connecting plate, a transverse rod and a hook, the side wall of the transverse rod is rotationally connected with the lower end of the connecting plate, and the side wall of the transverse rod is fixedly connected with the upper end of the hook; and the falling-off mechanism comprises a fixing frame, the side wall of the connecting plate is in sealed sliding connection with the inner bottom of the fixing frame, the lower end, close to the transverse rod, of the fixing frame is fixedly connected with a first sealing box, and the inner bottom of the first sealing box is in threaded connection with a threaded rod. When the weight of materials exceeds the load weight of a hook, a threaded cylinder drives a vertical rod and a rectangular rod to rotate forwards through a first bevel gear and a second bevel gear, a threaded rod is driven to rotate forwards, the threaded rod rotates to be separated from a threaded hole, a first T-shaped plate moves to be separated from a clamping groove, and at the moment, the hook directly rotates downwards under the action of gravity; and therefore, the hook cannot hoist the materials.

    本发明涉及挂钩技术领域,具体涉及一种防超重金属挂钩,包括:挂钩,所述挂钩由连接板、横杆和弯钩组成,所述横杆侧壁与连接板下端转动连接,所述横杆侧壁与弯钩上端固定连接;脱落机构,所述脱落机构包括固定框,所述连接板侧壁与固定框内底部密封滑动连接,所述固定框靠近横杆的下端固定连接有第一密封箱,所述第一密封箱内底部螺纹连接有螺纹杆。本发明在物料重量超过弯钩的荷载重量时,此时螺纹筒通过第一锥齿轮和第二锥齿轮带动竖杆和矩形杆正向转动,带动螺纹杆正向转动,使得螺纹杆转动与螺纹孔分离,并且第一T型板移动与卡槽分离,此时弯钩在重力作用下直接向下转动,使得弯钩不可以对物料进行吊起。
