Description

Technical Field

[0001] The utility model belongs to the field of building engineering construction, in particular to a novel safety belt buckle device. Background Art

[0002] Falling from height is one of the most frequent types of accidents in aerial work in the field of engineering construction. Among them, the causes of falling from height can be basically divided into three categories: accidents caused by improper management, accidents caused by improper use of protective measures, and accidents caused by unexpected emergencies. In order to ensure the safety of aerial workers, on-site workers are required to wear safety belts when performing such aerial work. Such safety belts mainly include laces worn on the body, which are connected to the safety belt, and the other end of the safety belt is connected to the buckle. The safety belt buckle is connected to the safety belt hanging point of the on-site structural member. The safety belt buckle is an important component connecting the operator and the safety belt hanging point. Its reliability determines the reliability of the entire set of safety belts and the safety of on-site workers. In the construction of scaffolding erection and dismantling, workers will choose not to wear safety belts because traditional lock buckles are difficult to effectively hang or inconvenient to hang, which will directly lead to the loss of the protection of the safety belt and the occurrence of high-altitude falls.
