Description

Technical Field

[0001] The utility model relates to the technical field of fireproof windows, in particular to a novel outward-opening fireproof window. Background Art

[0002] As part of a building, outward-opening fireproof windows can effectively prevent the spread of fire and protect the lives and property of people. Outward-opening fireproof windows can provide additional evacuation channels when a fire occurs, increasing the options and time window for people to escape. Especially in high-rise buildings or densely populated areas, this additional evacuation channel is particularly important. Outward-opening fireproof windows can be used in different fire partitions or isolation areas in a building to help prevent the fire from crossing different areas, thereby controlling the spread of the fire and reducing the losses caused by the fire.

[0003] The opening mechanism of some outward-opening fireproof windows may not be designed to be convenient or flexible enough, which may affect the ability of people to evacuate quickly and effectively using the fireproof windows in the event of a fire. Outward-opening fireproof windows usually consist of many parts and require regular inspection and maintenance to ensure their normal operation. However, due to their complex structure, there may be maintenance difficulties, especially in high-rise buildings or special environments. Utility Model Content
