The invention discloses a double-sided locking lifting hook which comprises a cavity, and a power assembly and a double-sided hook body are sequentially arranged in the cavity from top to bottom; the output end of the power assembly is in butt joint with the double-face hook body, and the double-face hook body slides in a sliding groove in the cavity. Locking rods are arranged on the two sides of the double-face hook body and connected into the cavity in a coupling mode. And when the double-sided hook body slides up and down, the locking rod is correspondingly opened and closed. And by designing the lifting hooks in two directions, the lifting effect can be effectively achieved when large heavy objects are used. By designing the mechanical cooperation of the power assembly and the locking rod, the locking effectiveness is ensured when a heavy object is pulled, and the quality phenomena such as unhooking are avoided.
本发明公开了一种双面锁止的起重吊钩,包括:腔体,所述腔体内由上至下依次设置有动力组件、双面钩体;所述动力组件的输出端对接于所述双面钩体上,且所述双面钩体位于所述腔体内的滑槽内滑动;位于所述双面钩体的两侧并轴接于所述腔体内设置有锁止杆;当所述双面钩体上下滑动时,所述锁止杆对应开合。通过设计了两个方向的吊钩,在面对大块重物时,能够有效的进行起重作用。通过设计动力组件和锁止杆的机械配合,保证在拉动重物时,锁止的有效性,不会出现脱钩等质量现象。
