Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, and in particular to a flexible safety belt for preventing falls from heights. Background Technology

[0002] In many high-altitude work scenarios, such as building construction, power tower maintenance, bridge construction and repair, and high-altitude cleaning operations, fall protection safety belts are personal protective equipment used in high-altitude work scenarios to prevent workers from accidentally falling and causing injury or death. Ensuring the safety of workers' lives is always the top priority.

[0003] Traditionally, safety belts with rigid structures are mostly used for protection. These safety belts are usually made of metal hooks, thick rigid connecting parts and webbing, such as common construction safety belts. The metal parts account for a large proportion. A safety rope is used to fix the safety belt, and the other end is fixed to the higher position where the work needs to be carried out.

[0004] In existing technologies, rigid safety belts are relatively heavy, and wearing them for extended periods can place an additional physical burden on workers, causing premature fatigue and indirectly affecting work efficiency and accuracy. In addition, safety belts have limited cushioning effect in the event of a sudden fall, and cannot minimize the injury to workers. Utility Model Content

[0005] This utility model proposes a flexible safety belt for preventing falls from heights, which aims to improve the problem that some existing devices have a large overall weight, which puts an extra burden on workers and makes it difficult to provide all-round support and protection, and has a limited buffering effect in response to sudden falls.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexible safety belt for preventing falls from heights, comprising a back connecting frame, one end of which is fixedly connected to a safety rope connection port, and the other end of which is fixedly connected to a back protective pad. A fixed connecting frame is fixedly connected to the bottom of the back connecting frame, and a connecting mechanism is provided at the bottom of the fixed connecting frame. An upper component is provided inside the connecting mechanism, and a safety mechanism is provided inside the safety rope connection port.

[0032] In use, one of the support buckles 3012 and the main safety buckle 301 are connected inside the safety rope connection port 101. The main buffer rope 302 begins to function. If the impact force continues, the first locking plate 303, in conjunction with the limiting tube 306, restricts the extension and retraction direction of the buffer spring 305. The buffer spring 305, made of high-quality alloy spring steel, is stretched under force, converting the impact energy into elastic potential energy to reduce the impact force. Subsequently, the secondary buffer rope 307 takes over to continue buffering and supporting, and the second locking plate 308 ensures its stability. The buffer protective shell 309 protects the main buffer rope 302 and the secondary buffer rope 307 throughout the process. The secondary safety buckle 3010 is connected to the safety fixing belt 3011 and fixed to the target object with the help of another support buckle 3012, completing the entire safety protection process.
