The invention provides an anti-falling electromagnet, and relates to the technical field of electromagnets, the anti-falling electromagnet comprises a lifting plate, a suction plate and an electromagnet, the electromagnet is arranged between the lifting plate and the suction plate, a lifting lug is arranged at the edge of the top of the lifting plate, a lifting hook part is installed on the lifting lug, the lifting hook part is connected with a lifting cable, and the lifting cable is connected with the suction plate. The lifting hook part comprises a hook body, a first sliding rod and a second sliding rod, the first sliding rod and the second sliding rod are movably installed on the two sides of the interior of the hook body respectively, and the lower end of the first sliding rod and the lower end of the second sliding rod both penetrate out of the hook body; a first gear and a second gear are rotationally arranged at the lower part in the hook body; the lifting hook part is connected with the lifting lug, the electromagnet pulls the hook and the first sliding rod to move downwards, and the second sliding rod is driven to synchronously move downwards through the linkage effect of the first gear and the second gear and the matching effect of the first meshing tooth and the second meshing tooth till the lower end makes contact with the hook, so that the first sliding rod and the second sliding rod are dynamically locked; the opening is sealed, and the lifting lug is prevented from falling off.

    本发明提供了一种防脱落型电磁铁,涉及电磁铁技术领域,包括吊板、吸板和电磁铁,所述电磁铁设在吊板和吸板之间,所述吊板顶部的边缘处设有吊耳,且吊耳上安装有吊钩部,所述吊钩部上连接有吊索,所述吊钩部包括钩体、第一滑杆和第二滑杆,所述第一滑杆和第二滑杆分别活动安装在钩体内部的两侧,且第一滑杆和第二滑杆的下端均贯穿出钩体;所述钩体内部的下方转动设有第一齿轮和第二齿轮;本发明通过吊钩部与吊耳连接,电磁铁拉动挂钩以及第一滑杆向下移动,通过第一齿轮和第二齿轮的联动作用,以及第一啮合齿和第二啮合齿的适配作用,驱动第二滑杆同步向下,直到下端接触挂钩,使得第一滑杆和第二滑杆动态锁定,封住开口,避免吊耳脱落。
