CN223765902U - Hook for hoisting machinery - Google Patents

Abstract

This utility model provides a hook for lifting machinery, relating to the field of lifting machinery technology. It includes a hook structure and a fixing structure. The fixing structure is connected to the inner cavity of the hook structure. In use, pulling the outer stop block opens the hook, which is then passed through the lifting point of the cargo. The connecting part of the cargo is placed in the placement groove, where an anti-slip layer provides anti-slip protection. After the cargo is secured, a spring pushes the limiting frame and the limiting block to rise and lock onto the outer ring of the fixing plate, preventing the stop block from shifting due to cargo movement. For disassembly, simply pull down the pull rod to retract the limiting frame into the sliding groove, opening the stop block and the fixing plate. After lifting, the orientation of the cargo can be adjusted by rotating the fixing ring on the outer ring of the support plate, thereby achieving stable anti-detachment of the lifting machinery hook and improving the safety of the device.
