[0003] The thermal insulation performance of common building doors and windows is generally installed on the surface of the box. The box is heated to measure the thermal conductivity and air tightness of the doors and windows. When testing the building doors and windows, the doors and windows need to be installed in the measuring port of the box. However, due to the large number of building doors and windows that need to be tested, after the doors and windows are tested, they need to be disassembled and replaced with another door and window installed in the measuring port for testing.
