Description

Steel construction threshold single leaf protective airtight door that lives

Technical Field

The utility model relates to a protective airtight door technical field, concretely relates to steel construction threshold single leaf protective airtight door alive.

Background

The protective airtight door is also called a civil defense door, and refers to protective equipment installed at an entrance and an exit of civil protection engineering, and is mainly used for blocking shock waves and isolating toxic gases, and when an accident occurs, the safety of people can be guaranteed by closing the protective airtight door. According to the opening and closing mode of the protective airtight door, the door can be divided into a fixed door threshold, a falling type door threshold and a movable door threshold. The fixed doorsill has low manufacturing cost, but cannot move, so that people and vehicles cannot conveniently get in and out; the falling type threshold needs to overcome gravity when being opened and closed, the required driving power is large, and the manufacturing cost is high.

The existing product airtight door is poor in sealing effect, low in structural strength, incapable of meeting daily production and application requirements of people, inconvenient to install, incomplete in structure, poor in protective safety performance, and the safety lock can only be controlled in a single face again, so that toxic gas shock waves and the like are not conveniently prevented from being isolated.
