Description

Technical Field

[0001] The utility model belongs to the technical field of door and window detection, and particularly relates to a door and window airtightness detection device. Background Technique

[0002] Doors and windows are important components of a building. They not only provide rich decorative effects for the building facade but also are an important link in controlling building energy consumption. When installing doors and windows, it is necessary to detect the sealing performance of the doors and windows. The sealing performance of the doors and windows determines the overall airtightness and sound insulation effect of the building. Therefore, the sealing performance of the doors and windows is an important indicator for measuring the quality of the doors and windows.

[0003] When the existing airtightness detection equipment detects doors and windows, it often fixes the sample doors and windows in the equipment to form a sealed space in the equipment. Then, gas or smoke is filled on one side of the enclosed space, and a sensor or a precision detection instrument is set on the other side of the enclosed space. If the sensor or the detection instrument does not detect gas or smoke during the detection process, it means that the airtightness of the doors and windows is qualified, otherwise it is unqualified.

[0039] Please see Figure 5 and Figure 6 The positioning plate 4 is set on the side wall of the mounting groove 2. The positioning plate 4 is ring-shaped and can be welded to the side wall of the mounting groove 2. A groove is provided in the middle of the side wall of the positioning plate 4 near the groove opening of the mounting groove 2. The sample door and window Y can be positioned through the groove. The size of the groove is designed according to the common door and window size. The inner circle of the groove should be smaller than the frame size of the sample door and window Y.

[0040] Please see Figure 4 The clamping member 5 can cooperate with the positioning plate 4 to fix the sample door and window Y on the positioning plate 4. At this time, the mounting groove 2, the positioning plate 4 and the sample door and window Y form a sealed detection space. In the prior art, the structure that can clamp and fix the sample door and window Y on the positioning plate 4 and release the sample door and window Y after the detection can be used as the clamping member 5 in this embodiment.

[0041] For example, in this embodiment, please refer to Figure 5 The positioning plate 4 is provided with a plurality of threaded holes 401. Preferably, the plurality of threaded holes 401 are distributed at intervals along the circumferential direction on the positioning plate 4. Please refer to [link to relevant documentation].
