Embodiment 2

[0041] refer to figure 1 , 5 And 6, an on-site airtight performance detection device for building doors and windows, which is basically the same as Embodiment 1, furthermore, the locking part includes a screw mandrel 204 and a nut 205, the screw mandrel 204 is fixedly connected to the detection box 1, and the nut 205 Threaded connection with the screw rod 204; when the sealing cover 2 is closed, first put the nut 205 on the screw rod 204, and then turn the nut 205, at this time the nut 205 moves to the side of the detection box 1, pushing the seal on the inner side of the sealing cover 2 The pad 201 is closely attached to the top of the detection box 1, thereby improving the sealing performance of the connection between the sealing cover 2 and the detection box 1, avoiding air pressure leakage, and affecting the detection result of the wind pressure resistance of the doors and windows.

Embodiment 3

[0043] refer to Figure 4 , 7 And 8, an on-site airtight performance detection device for building doors and windows, which is basically the same as Embodiment 1, furthermore, the fixed parts include a sealing strip 702, a vacuum suction cup 28, a piston cylinder 801, an electric telescopic rod 803, and a sealing strip 702 1. Vacuum suction cup two 8 are all fixedly connected on the detection board 7, the piston cylinder 801 and the electric telescopic rod 803 are all fixedly connected on the bottom of the detection board 7, the vacuum suction cup two 8 is connected with the piston cylinder 801 through the third conduit 804, and the piston cylinder 801 There is a piston plate 802 slidingly connected inside, and the piston plate 802 is fixedly connected with the output end of the electric telescopic rod 803; when the airtightness of doors and windows is tested, the electric telescopic rod 803 is started, and the electric telescopic rod 803 drives the piston plate 802 to move aw...

Abstract

The invention discloses a building door and window on-site airtight performance detection device, and belongs to the technical field of airtight performance detection equipment. The building door and window on-site airtight performance detection device comprises a detection box and a sealing cover, the sealing cover is rotatably connected to the detection box, the device further comprises a pressurization bin arranged in the detection box, and a detection bin capable of accurately detecting air leakage parts of a door and a window is arranged below the pressurization bin; and a motor is fixedly connected to the side wall of the detection box; while the airtight performance of the door and window is detected, the wind pressure resistance of the door and window can be detected, then in the detection process, the part, with poor air tightness, of the door and window can be accurately detected, meanwhile, the sealing performance of the connecting position of the sealing cover and the detection box can be improved, the condition that detection result of the door and the window is affected due to the leakage of air pressure in the pressurization bin through a gap is is prevented, automatic loading and unloading can be realized, so that the labor intensity of workers is reduced, and the detection efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of airtightness testing equipment, in particular to an on-site airtightness testing device for building doors and windows. Background technique [0002] The air tightness of doors and windows refers to the length of the opening seam of doors and windows or the amount of air permeation per unit area. It assesses the ability of doors and windows to prevent air infiltration when they are closed. On-site inspections of building doors and windows are usually done before the installation of doors and windows. However, the existing air-tightness detection device has a single function. When testing the air-tightness of building doors and windows, it cannot accurately detect the parts with poor air-tightness of doors and windows, which reduces the air-tightness of doors and windows. The effect of the detection, and the need to manually put the building doors and windows into the detection equipment for detection, and...
