Technical Field
[0001] The utility model relates to the field of mechanical processing, in particular to a safety hook. Background Art
[0002] Hooks are divided into single hooks and double hooks according to their shapes; they are divided into forged hooks and laminated hooks according to their manufacturing methods. Single hooks are simple to manufacture and easy to use, but they are not good at bearing force. They are mostly used in workplaces with a lifting weight of less than 80 tons; double hooks with symmetrical force are often used when the lifting weight is large. Laminated hooks are made of riveted steel plates cut and formed from several pieces. When cracks appear on individual plates, the entire hook will not be damaged. It has good safety, but it has a large deadweight and is mostly used on cranes with large lifting weights or for lifting molten steel buckets. Hooks are often impacted during operation and must be made of high-quality carbon steel with good toughness. Hooks are widely classified, generally including: shackles, rings, round rings, pear-shaped rings, long rings, combined rings, S hooks, nose hooks, American hooks, horn hooks, eye-shaped sliding hooks, screws with safety cards, chain shackles, which are unique, novel, high-quality and safe, and are suitable for factories, mines, petroleum, chemical industry and ship docks.
[0003] However, traditional hooks are relatively simple, without a safety pin plate to block the hook position. During the process of lifting heavy objects, the hook is prone to unhooking. During long-term lifting, there is a risk of falling objects from high altitudes. The overall operational safety factor is low, and there is no safety protection on the top of the hook, resulting in a safety hazard of the product falling off during use.
