Descender for escaping

Abstract

The invention belongs to the technical field of high-rise emergency escape, and relates to a safe escape apparatus used for taking sanctuary, in particular to a descender for escaping. The descender comprises connecting plates, a pull rod and a gear; an arch piece 5 is arranged at one side at the upper part of a main connecting plate 1, and the outer side of the arch piece 5 is provided with a connecting pull rod 4 connected by an eccentric bolt 3; a first convex gear 8 and a second convex gear 10 which are meshed with each other are arranged at the other side of the main connecting plate 1 ina juxtaposed way; the first convex gear 8 and the second convex gear 10 are provided with auxiliary connecting plates 2; the first convex gear 8 is connected with a spanner 7; the second convex gear10 is provided with a through hole and is connected with the upper end of a connecting piece 11 by screws. Compared with the prior art, the descender has the remarkable characteristics of low price, simple structure, convenient and safe operation as well as being simultaneously used by a great deal of people by using one rope for escaping. The descender for escaping is applicable to emergency suchas fire in high-rise building and the like, and has better practicability and market application prospect.

Description

technical field [0001] The invention belongs to the technical field of high-rise emergency escape, and belongs to a safety escape device for refuge, in particular to a descent device for escape. Background technique [0002] With the continuous development of economy and technology, the number of high-rise buildings in our country is increasing, especially in cities, and the number of high-rise buildings is increasing. How to take emergency escape in the event of an accident. Because there are often reports on TV that the occupants of a high-rise building were caught in a fire. In desperation, some people often jumped from the high-rise to the ground to escape. Some tear the sheets into strips and connect them into ropes with a certain length to slide down the window to the ground, etc...

Problems solved by technology

Because there are often reports on TV that the occupants of a high-rise building were caught in a fire. In desperation, some people often jumped from the high-rise to the ground to escape. Some tear the sheets into strips and connect them into ropes with a certain length to slide down the window to the ground, etc... These various emergency escape methods not only fail to protect the human body during escape, but often Although people will not be burned or smoked by jumping from a building, many results are regrettable, because people often suffer different degrees of damage to their bodies due to such escapes, and cannot recover. Because of falling to death like this, especially when the floors are higher, the trapped people have no hope of escaping from the window; more direct and serious harm to the human body

[0003] Because the corridors, corridors or safe passages on many floors are often neglected by people, they are often used to pile up sundries, and some safe passages are even tightly locked. Once such a high-rise building is on fire, Fireworks will spread to these places at the fastest speed and block them, making it impossible for trapped people to reach the ground safety zone safely and smoothly from these places

Therefore, the problem of how emergency escape in high-rise buildings has also been more and more paid attention to and paid attention to by people. At present, various escape devices have appeared, but some have unsmooth descending speeds, cannot control the speed of descending speeds, and some Unable to escape with multiple people at the same time
