Description

Technical Field

[0001] The utility model belongs to the technical field of double-wing revolving doors, in particular to a double-wing revolving door with an emergency personnel evacuation structure. Background Art

[0002] Double-wing revolving door, also known as two-way revolving door or double-wing revolving door, is a uniquely designed door system, commonly found at the entrances of high-end hotels, large shopping malls, commercial office buildings and other places. Its main feature is that it has two door wings that rotate relative to each other, providing a spacious, elegant and efficient passage experience for people entering and leaving. In daily use, most double-wing revolving doors are used to push the door to rotate for the purpose of passage, and can achieve the effect of entry and exit at the same time. However, when an emergency occurs and people need to be evacuated, the common double-wing revolving door cannot achieve rapid evacuation of people. It is necessary to continuously push the revolving door to rotate to achieve the passage of people. In addition, the number of people passing at one time is limited, which will cause congestion, trampling, etc., which will endanger the safety of people.

[0003] Secondly, the inability to evacuate quickly in an emergency will prevent some people from passing through to the outside of the building within a certain period of time, and they will be stranded inside the building, which will also pose certain safety hazards and endanger the personal safety of people in serious cases.

[0004] In summary, the double-wing revolving door cannot be used to quickly evacuate people in an emergency situation and there are some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
