Abstract

The invention provides an anti-smog handrail. The anti-smog handrail employs an air supply pipeline. The pipe wall of the air supply pipeline is provided with an opening along the length direction ofthe pipeline; both sides of the opening are respectively connected to a chain belt I and a chain belt II; one side edge of the chain belt I is provided with arrayed chain teeth I; one side edge of thechain belt II is provided with arrayed chain teeth II; a ventilation sliding block device is disposed on a joint between the chain belt I and the chain belt II; the ventilation sliding block device can slide on the chain belt I and the chain belt II; the structure of the ventilation sliding block device includes two guiding mouths, a bottom plate, a cover plate and inner core bodies; the bottom plate is connected to the cover plate through the inner core bodies; a gap is disposed between the bottom plate and the cover plate; in the outer sides of the guiding mouths of the ventilation slidingblock device, the chain teeth I of the chain belt I are meshed with the chain teeth II of the chain belt II; the chain teeth I and the chain teeth II located inside the ventilation sliding block device are opened by the inner core bodies; and the bottom plate or the cover plate of the ventilation sliding block device inside the air supply pipeline is provided with an air outlet hole.

Description

technical field [0001] This application relates to a handrail. 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 technical scheme, the escaped people ...
