Description
Technical Field
The invention belongs to the technical field of furniture, and particularly relates to a disaster avoidance bed for a high building.
Background
When an earthquake of a large magnitude occurs, life safety of residents in a high-rise building is seriously threatened. When an earthquake happens excessively, the whole building collapses, most of technologies related to life after disaster of high-rise buildings are mainly concentrated on escape, such as various escape ladders, escape ropes, escape boxes and the like, but the elevators and facilities under all conventional conditions cannot be normally used after the disaster occurs, in a very short time interval, the practically available escape means are few, the effect is limited, and residents in the high-rise buildings are difficult to escape in a short time. Large fires present a fatal threat to residents in high-rise buildings. After a fire disaster occurs, the heat waves and toxic gases at the bottom layer can quickly rise upwards, the flame can ignite combustible matters in the building together with the heat insulation layer of the outer wall of the building, the power supply system can be quickly destroyed, and high-rise residents can quickly suffocate in the high-temperature and toxic gases to die.
When strong earthquake happens, if disaster avoidance is successful and survives, but because the narrow safety space where survivors are located is easily damaged by disturbance of external force, large-scale equipment cannot be used for excavating and searching, even if vital signs at the bottoms of ruins are detected from the outside, excavating and searching and rescuing cannot be rapidly unfolded, so that many people lose the chance of being rescued and survived.
Along with the increase of high-rise buildings around the world, the escape and danger avoiding problems of the high-rise buildings after earthquake and fire disaster occur are also attracting more and more attention. In this context, escape is not an intelligent choice, but avoidance may guarantee life safety of a person, and may make a person possible. Currently, there are some important or special institutions, and refuge cabins (cabinets) are arranged in high-rise buildings so as to ensure the life safety of people in the event of disasters. However, the special mechanism is rarely adopted in civil buildings, is not practical, cannot be used as a special mechanism at ordinary times, and wastes precious indoor space. These disasters are after all a small probability event for most residents of high-rise buildings, such as a valuable living space, and it is difficult for most people to place a large article which may never be used.

6. After the external state is stable and no danger is determined, the observation window 13 can be opened to observe, ventilate or call for help.
7. Under the condition that no person is rescue, the positioning device in the emergency box 17 is opened to send out a distress signal, and meanwhile, life energy can be supplemented when emergency substances in the emergency box 17 wait for rescue for a long time.
8. After the rescue workers arrive, external obstacles are cleared, the spherical handle 142 is pulled from the outside, the locking mechanism 14 is opened, the hatch 21 is opened, and disaster avoidance workers are saved.
