Description

Technical Field

[0001] The utility model relates to the field of building air tightness testing devices, in particular to a convenient building air tightness testing device. Background Art

[0002] Under the action of wind pressure and heat pressure, air tightness is an important control indicator to ensure the stability of the thermal insulation performance of the building's exterior windows. The air tightness of the exterior windows is directly related to the heat loss caused by cold wind penetration of the exterior windows. The higher the air tightness level, the smaller the heat loss. The air infiltration of the building mainly comes from the loose holes in the ground floor doors, external doors and windows and the external protective structure.

[0003] Since the infiltration and outflow of air cannot be measured directly, but while maintaining the indoor pressure of the building unchanged, the average amount of gas entering and exiting the leakage is the same as the gas flow rate entering and exiting through the airflow device. Staff usually need to seal the door position and inflate the room. However, the sizes of doors of different houses are different, and traditional detection devices are difficult to meet the needs. In addition, the amount of air leakage from different doors is also different. Therefore, traditional detection devices are difficult to cope with the stability of the airflow field in different states, which affects the monitoring results. Utility Model Content

[0006] The corner connection assembly comprises a rectangular sealing block, and the two long rods are respectively fixedly mounted on adjacent sides of the sealing block.

[0007] The cloth cover is made of windproof nylon canvas, a plurality of magic strip male buckles are sewn on the surface of the cloth cover, and magic female buckles are sewn on the cloth cover at vertical or horizontal positions corresponding to the magic strip male buckles.

[0008] A nozzle is installed at the air inlet of the fan.

[0009] The air inlet of the fan is installed with a first magnetic buckle, and the corresponding positions of the nozzles are installed with second magnetic buckles.

Figure 4 As shown, the adjacent sides of the locking handle 6 are set as flat surfaces, the connection position is set as an arc surface, and a positioning knob is set in the middle to fix the position of the locking handle 6. A control device is provided on the outside to control the fan 3.

[0022] Use two long rods 4 to place inside the door frame and stretch them to the maximum size. Then use the locking handle 6 to relatively fix the positions of the two long rods 4, and press the whole onto the door cover, with the bottom as the installation reference. The left and right directions are symmetrical. The cloth cover 1 is folded from the lower part of the door frame to the upper part and covered with the outer frame. The fan 3 is installed at the position of the interface groove 2. A crossbeam consisting of two long rods 4 and the locking handle 6 can also be installed in the middle of the door frame to ensure the firmness of the cloth cover 1. A cloth belt is wrapped around the crossbeam to connect and fix the fan 3. At this time, an air tightness test can be performed.
