Abstract

The invention provides an air supply pipeline for providing breathing air. The air supply pipeline is characterized in that an opening or openable opening is formed in a pipe wall of the air supply pipeline; the pipe walls on the two sides of the opening are separated and are away from each other by a certain distance or the pipe walls on the two sides of the opening are combined into a crack; the length of the opening is equal to the length of the air supply pipeline or the length of the opening is smaller than the length of the air supply pipeline; the pipe wall on one side of the opening is fixedly connected with one end of a sealing strip; the other end of the sealing strip and the pipe wall on the other side of the opening are in magnetic attraction or the other end of the sealing strip and another sealing strip connected with the pipe wall on the other side of the opening are in magnetic attraction; vent pipes can be inserted into the opening and communicate with inner holes of the air pulley pipeline after the sealing strips are moved; and the sealing strips wrap the vent pipes through magnetic attraction or the pipe wall, on the side edge of the opening, of the air supply pipeline wraps the vent pipes.

Description

technical field [0001] The present application relates to an air supply duct for supplying breathing air. Background technique [0002] In building fires, smoke is the main cause of preventing people from escaping and causing the death of trapped people. [0003] When a fire breaks out in a building, in order to avoid the damage of smoke to people, the prior art is as follows: an air supply pipeline is arranged inside or outside the structure of the building, and the above-mentioned air supply pipeline is provided with an air outlet at a suitable position on the floor. The air inlet of the air supply pipeline extends to the outside of the building to communicate with the gas outside the building, and the air supply pipeline extends downwards and then extends a certain distance to the outside of the building. Therefore people can inhale the air that is not affected by smog by means of the air outlet, then hold back the breath and advance for a period of time such as 5-20 sec...
