Description

technical field [0001] The present application relates to an air outlet device for chain belts. Background technique [0002] 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 to the outside of the building for a certain distance, because the smoke generated during the fire flows upwards Therefore, the air below the building generally does not have smog, and the possibility of smog appearing in a place such as extending a distance of 10 meters to the outside of the building is even lower. After adopting the above-mentioned tech...
