It can help improve the quality and performance of building doors and windows, and ensure that the building has good sealing and wind pressure resistance under various environmental conditions. In order to ensure the quality requirements of building doors and windows, it is usually necessary to conduct three-property tests on building doors and windows.

[0003] For example, the publication number CN211626910U discloses a detector for the three properties of building doors and windows, the main points of the technical solution are: comprising a frame, a first pressing plate arranged on the frame, a second pressing plate arranged on the frame and a clamping device arranged on the frame, a guide member is arranged on the frame, a driving mechanism is arranged between the frame and the second pressing plate, the second pressing plate is connected to the guide member by sliding in the horizontal direction, the driving mechanism is used to drive the second pressing plate to slide back and forth on the guide member, and a detection cavity is formed between the first pressing plate, the second pressing plate and the frame. The utility model has the function of facilitating the position adjustment of the second pressing plate, which has the effect of reducing human labor in the process of adjusting the position of the second pressing plate;

[0004] However, the detector in the above application still has some shortcomings during use.

In addition, when encountering windows of different heights, it is not convenient to adjust the height of the detector, and it cannot be suitable for more detection needs, which brings inconvenience to the staff's detection operation, thereby reducing the use effect of the detector. Therefore, we propose a door and window three-property detector with a sealing structure to solve the above problems. Utility Model Content
