Description

Technical Field

[0001] The utility model relates to the technical field of exterior window detection, in particular to a sealing device used for tightness detection of exterior windows. Background Art

[0002] Windows mainly serve the functions of lighting, ventilation and sealing. After the production and installation of windows, the air tightness of windows needs to be tested to understand the performance of windows. The conventional testing method is: use tape to stick the plastic film to the walls around the window, so that the plastic film and the window form a sealed cavity, and then fix the pipe of the testing instrument on the plastic film, and stick it with tape, so that the pipe and the plastic film are sealed. The sealing effect of the window is measured by blowing air to the other side of the window, and then using the testing instrument to detect the amount of air that penetrates the side of the window sealed by the plastic film.
