Abstract

The invention relates to a high-altitude escape self-rescue device, which comprises a shell and a rope, wherein a handle is fixedly connected with a lead screw in the shell; the left and right elliptical threads of the lead screw are connected with left and right slide blocks respectively; the left and right slide blocks are connected with two feeding rods in a sliding way; left and right movable pulleys are hinged with the left and right slide blocks respectively; two fixed pulleys are hinged with left and right brackets respectively; the left and right brackets are fixedly connected with the shell; the rope is wound on the two fixed pulleys in a staggered way, and is arranged between the two movable pulleys; the top surface of the shell is provided with a rope inlet positioning mechanism; and the bottom surface of the shell is provided with a rope outlet and a lug where a safety vest is arranged. The device has a simple structure, high manufacturability, small size and light weight, is smooth and safe, and is easy and convenient for operating.

Description

Technical field [0001] The invention relates to a lifesaver, in particular to a high-altitude escape self-rescue device. Background technique [0002] With the rapid development of the country’s economy and the continuous improvement of people’s living standards, there are more and more high-rise buildings in cities. When accidents such as fires occur, it is more difficult for people in the buildings to escape. It cannot be used due to power outages, and the stairway will be blocked due to overcrowding. People can only be trapped in the building and passively wait for rescue. Currently, the used escape device has a complicated structure, is difficult to assemble, has an unstable lowering speed, and is inconvenient to operate. Summary of the invention [0003] The purpose of the present invention is to overcome the technical shortcomings of the existing high-altitude escape device and design a high-altitude escape self-rescue device with simple structure, stability and safety, sim...
