AI Technical Summary
In the prior art, when testing the airtightness of windows, the slight deformation caused by the opposing clamping of the frame by the clamping device leads to inaccurate test results.
An internal and external clamping mechanism is used to vertically clamp the edge of the sample window. Combined with a drive mechanism and sliding groove design, the opposing compression of the frame is avoided. A sealing cover and a pressure sensor are used for real-time airtightness detection.
This effectively prevents slight deformation of the window frame, ensuring the accuracy and reliability of the test results.
