Safety belt rope tension spring buffering device

Abstract

The invention discloses a device in the technical field of safety belts. A safety belt rope tension spring buffering device is characterized in that a certain length is reserved in the middle part ofa safety belt rope of a safety belt and is smaller than the maximum tensile elasticity extremity length of a tension spring, two ends are bound at upper and lower circular rings at two ends of the tension spring, excessive safety belt is wound around in the inside of the tension spring, and heating and tensioning are performed to protect the tension spring against damage after a heat shrinking tube sleeves. When the rope is tightened under the accidental dropping situation in the using process, the tension spring is forced to stretch at the moment, and the dropping speed of the tension springis from high to low and finally stops. For example, the tension spring is damaged and invalid, the rope wound in the tension spring plays a dropping stopping effect, and continuous dropping is prevented. The safety belt rope tension spring buffering device has the advantages that the body impact pull injury, caused by rapid dropping or even sudden stop, of a user under the accidental dropping is prevented, and the safety belt rope tension spring buffering device is simple in structure, safe and good in practicability and achieve the buffer protection effect in the accidental dropping process.

Description

technical field [0001] The invention relates to the field of safety belt technology industry, in particular to a safety belt rope extension spring buffer device. Background technique [0002] Known safety belt protection articles on the market at present, the main function of safety belt is to fix the hook in the work area [0003] On a nearby solid object, in case of an accidental fall, there is only a simple rope impact and pull protection, which is easy to cause impact and pull damage. The safety belt of the buffer device only has a simple adhesion type, which does not have linear cushioning characteristics. There is randomness and safety is unstable and reliable, so it is not very suitable for the buffering of personnel safety buffering and accidental fall. Contents of the invention [0004] The object of the present invention is to provide a safety belt rope extension spring buffer device to solve the problems raised in the above background technology. [0005] In o...

[0003] On a nearby solid object, in case of an accidental fall, there is only a simple rope impact and pull protection, which is easy to cause impact and pull damage. The safety belt of the buffer device only has a simple adhesion type, which does not have linear cushioning characteristics. There is randomness, security is unstable and reliable, and it is not very suitable for buffering when personnel safety buffers accidentally fall.
