Description

Technical Field

[0001] The utility model relates to the technical field of rolling shutter doors, in particular to a fireproof rolling shutter with a positioning mechanism. Background Art

[0002] Industrial buildings such as factories and warehouses usually store a large number of flammable items or chemicals, which may cause huge losses in the event of a fire. Fire shutters can confine fires to specific areas, reduce losses, and provide escape routes for workers. Residential buildings such as high-rise residential buildings and apartments also need to consider fire protection. Fire shutters can cut off the fire when a fire occurs, extend the escape time, and improve the safety of residents. Fire shutters protect the lives and property of people by responding to fires in a timely manner and effectively controlling the spread of fire.

[0003] When the existing fireproof rolling shutter moves, there is no fixed positioning mechanism for the rolling shutter door curtain, which causes the rolling shutter door curtain to easily deviate when moving, resulting in poor stability during the rolling process of the rolling shutter door.
