Emergency escape ladder used for high-rise building fire accidents

Abstract

The invention discloses an emergency escape ladder used for high-rise building fire accidents. The emergency escape ladder comprises a sandwich wall. A storage cavity with an upper opening and a loweropening is formed in the sandwich wall. A supporting frame is fixedly arranged on the right wall of the storage cavity. A ladder mechanism capable of sliding downwards to be unfolded or being stackedupwards to be folded is fixedly arranged on the left side of the supporting frame. The ladder mechanism sequentially comprises a first ladder, a second ladder, a third ladder and a fourth ladder fromleft to right. The first ladder, the second ladder, the third ladder and the fourth ladder are connected with one another in a sliding manner. A user can directly go downwards to the lower floor conveniently and rapidly when the fire accidents are caused to high-rise buildings and ladders in the buildings cannot be used; and meanwhile, when no fire disasters happen, residents on upper floors canbe prevented from entering lower floors, and residents on the lower floors can be prevented from entering the upper floors.

Description

technical field [0001] The invention relates to the technical field of escape ladders, in particular to an emergency escape ladder used in high-rise building fire accidents. Background technique [0002] At present, with the continuous development of society and the continuous increase of population, buildings are built higher and higher. During the use of such high-rise buildings, if a fire accident occurs, it will be very difficult to rescue. Moreover, general fire accidents often close the stair passage, making it difficult for the residents in the room to escape, and it is difficult for rescuers outside the building to enter. There are also some escape devices on the market, but if you escape from a high floor, it will still be dangerous. Open an escape hatch between floors, but in normal times, this will affect security issues. In order to reassure residents about security and to escape easily in the event of a fire, it is necessary to design an emergency escape ladder ...
