Description

Technical Field

[0001] The utility model relates to the technical field of fireproof rolling shutter doors, in particular to a fireproof rolling shutter door which is easy to install. Background Art

[0002] Fire shutters are a common fire protection device used to prevent the spread of fire and protect people's lives and property. They are typically made of metal materials such as steel plates and held together by buckles or hinges. Under normal circumstances, the shutters are rolled up and stored in a hinged box at the top of the door or window. In the event of a fire, they automatically lower and deploy, preventing the fire from spreading through the door or window opening.

[0003] In the prior art, fireproof rolling shutter doors generally use a rolling shutter machine to drive them to open and close. The rolling shutter machine is generally installed on the upper part of the shutter, which is a high-altitude operation. Two installation workers are required to lift the rolling shutter machine and install the fixing screws at the same time, which wastes human resources. At the same time, due to the large size of the rolling shutter machine, the installation efficiency is low, and it may cause injuries caused by the rolling shutter machine falling. For this reason, we propose a fireproof rolling shutter door that is easy to install. Utility Model Content
