Description

Technical Field

[0001] The utility model relates to the technical field of hooking, in particular to a hooking mechanism for a safety belt. Background Art

[0002] In the construction industry, hard hats, safety belts, and safety nets are the "three treasures" of construction workers. The lack of any one of them will cause fatal injuries to construction workers. Hard hats are not unfamiliar to everyone, but the use of safety belts is not so common. In addition to construction workers, other types of workers also need safety protection equipment-safety belts in high-altitude operations.

[0003] During the construction of high-altitude steel structures, construction workers need to frequently walk on steel beams to perform welding, pipeline installation, etc. In order to ensure their own safety, construction workers in high-altitude working environments must wear safety belts, but in most cases, there are no reliable safety belt hook points on the steel pipe structure. Since there are no safety belt hook points on site, workers cannot wear safety belts to work, that is, when workers work without fall protection, there is an industrial safety risk of falling from heights.

[0004] In order to solve the above problems and protect the safety of the workers, a hook mechanism for a safety belt has been developed. Summary of the invention
