Detection device for on-site airtight performance of building door and window

Abstract

The invention provides a detection device for on-site airtight performance of a building door and window, and relates to the field of door and window air tightness detection. The device comprises a fixing base, a horizontal adjusting mechanism is fixedly installed on the upper surface of the fixing base, a vertical adjusting mechanism is arranged at the top of the horizontal adjusting mechanism, an installation plate is arranged on the outer side wall of the vertical adjusting mechanism, and a fixing mechanism is arranged on the upper surface of the installation plate. The horizontal adjustingmechanism and the vertical adjusting mechanism are adjusted so that the detection assembly is located at the edge seam of a to-be-detected door and window; then the other side of the door and windowslowly blows air along a gap of the door and window by utilizing a fan; and meanwhile, whether powder enters the corresponding rear holes or not is observed through the transparent blocks, so that whether the airtightness of the door and window has problems or not is judged, the whole device has no excessive requirements for the airtightness, operation is convenient, meanwhile, the position wherethe airtightness has problems can be further determined, and an operator is prevented from improving the airtightness.

Description

technical field [0001] The invention relates to the technical field of door and window airtightness detection, in particular to an on-site airtightness detection device for building doors and windows. Background technique [0002] The airtightness of doors and windows refers to the unit opening seam length of doors and windows or the amount of air infiltration per unit area. It assesses the ability of doors and windows to prevent air infiltration when they are closed. The on-site inspection of building doors and windows is usually before the completion and acceptance of building doors and windows. Airtightness and sound insulation have a relative relationship. If airtightness is poor, sound insulation will naturally be bad. Doors and windows with poor airtightness will bring greater noise and affect people's health.

AI Technical Summary

Problems solved by technology

[0005] To sum up, the above-mentioned technical solutions have certain advantages, and can detect the airtightness of doors and windows. However, the above-mentioned solutions still have certain deficiencies. For example, when the device is in use, it requires high sealing performance, so It increases the operational difficulty of the whole device, and the detection device can only unilaterally judge whether there is a problem with the airtightness of doors and windows, but cannot locate the specific location where the problem exists in the airtightness.
