Abstract
The utility model discloses a novel shielding and closed observation window. The novel shielding and closed observation window comprises an observation window frame and perspective parts arranged inside the observation window frame, wherein the perspective parts comprise first perspective glass, second perspective glass and third perspective glass; a first shielding net is arranged between the first perspective glass and the second perspective glass; and a second shielding net is arranged between the second perspective glass and the third perspective glass. With the adoption of the manner, the novel shielding and closed observation window can be closed and perspective, and also has better shielding performance.
Description
Technical field
The utility model relates to the civil air defense constructions and installations technical field, particularly relates to a kind of novel shielding, airtight observation window.
