Piston air damping type high-rise building safety escape device

Abstract

The invention discloses a piston air damping type high-rise building safety escape device and belongs to the technical field of safety, rescue and escape devices. The device is characterized in that an inner sleeve and an outer sleeve are in clearance sliding matching; an air inlet hole is arranged at the inner end of the inner sleeve and a threaded rod is fixed on the outer end of the inner sleeve; the threaded rod is provided with an anti-rotating jack; outer fixing snap rings are in rotating matching with the outer sleeve; an inner sleeve anti-rotating sheet is fixed on each outer fixing snap ring; a nut is fixed on the outer end of the outer sleeve; an air inlet groove is arranged on the inner wall of the outer sleeve; the outer wall of the outer sleeve, between the two outer fixing snap rings, is provided with flexible silk ropes which are wound in sequence; and the inner ends of the silk ropes are fixed to the outer sleeve and the outer ends of the silk ropes are fixed to the link of a safe belt. The safety escape device guarantees the safety of life and property of people in high-rise buildings, does not need electricity or other energies as power, and can not be influenced by environment and seasons; in addition, the safety escape device can be installed easily and used conveniently.

Description

technical field [0001] The invention belongs to the technical field of safety, rescue and escape devices. Background technique [0002] All over the world, the rapid and safe evacuation of people in high-rise building fire hazards is still a problem that has not been well resolved. [0003] At present, the evacuation of people in high-rise building fire hazards mainly has the following methods: [0004] 1. Active self-rescue method: evacuate from the elevator or stairs of another building unit through the fire exits set between different building units; or use a wet towel to cover mouth and nose and forcibly evacuate from the stairs. [0005] 2. Passive rescue method: wait for the arrival of firefighters, rescue with professional equipment such as fire ladders, or forcibly jump off under the protection of professional fire safety air cushions to escape from the fire danger. [0006] Existing means of escape from fire hazards in high-rise buildings lack reliability and effe...

Problems solved by technology

[0006] Existing means of escape from fire hazards in high-rise buildings lack reliability and effectiveness: passive rescue may not be timely, and the effectiveness of facilities cannot be guaranteed; active self-rescue lacks fast and effective methods and simple and easy devices, so that in high-rise buildings When a fire breaks out in a building, it is difficult for people in danger to save themselves effectively and be quickly rescued, often causing a large number of casualties
