High-altitude escape self-rescue device

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 life-saving device, 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 the city. When accidents such as fires occur, it is difficult for people in the buildings to escape. If the power is cut off, it cannot be used, and the stairways will be blocked due to crowding. People can only be trapped in the building, passively waiting for rescue. At present, the used escape device has a complicated structure, difficult assembly, unstable descending speed, and inconvenient operation. Contents of the invention

[0003] The purpose of the present invention is to overcome the technical deficiencies of existing high-altitude escape devices, and design a high-altitude escape self-rescue device with simple structure, stable safety, easy opera...
