Description

Technical Field

[0001] The utility model relates to the field of air tightness detection of doors and windows, in particular to a detection box of an on-site external window air tightness detection device. Background Technique

[0002] To improve the light transmission and ventilation properties of buildings, windows need to be set on the outer circle of buildings, and external windows are set at the windows. According to the corresponding verification and calibration specifications, it is necessary to conduct air tightness detection on the external windows that are not installed and those that have been installed and are in use.

[0003] For the external windows that are not installed, the external windows can be directly transported to the testing unit, and the air tightness of the external windows can be detected by using the door and window testing machine of the testing unit. For the external windows that have been installed and are in use, the staff needs to carry the air tightness detection device to the site, first seal the periphery of the external window through the sealing device, and then use the air tightness detection device to detect the air tightness of the external window.

[0004] In the prior art, the on-site external window air tightness detection device is basically divided into three parts: a fan, a detection box, and two sections of air ducts. A pressure sensor and a flow sensor are arranged in the detection box. During specific detection, because there are many equipment components, multiple staff members are required to carry all the equipment components to the side of the on-site external window to be detected, use the sealing device to seal the periphery of the on-site external window, a sealing device interface is arranged on the sealing device, one section of air duct is used to connect the fan and the detection box, and another section of air duct is used to connect the detection box and the sealing device interface. The fan blows air to the sealing device interface through the two sections of air ducts. If the air tightness of the on-site doors and windows is not good, this blowing pressure will be lost relatively quickly, and the air tightness of the on-site doors and windows is judged according to the loss situation of the blowing pressure.

[0005] The problem of the on-site external window air tightness detection device in the prior art is that there are many parts, at least two staff members are required to carry them, which is not very convenient, and at least two air duct connections and installations are also required on site, which also increases the inconvenience of on-site use and is not conducive to improving the detection efficiency.

[0027] An embodiment of a field outer window airtightness detection device in the present utility model is as Figures 1 to 3 shown: It includes a detection box, an air duct (air pressure collection pipe) and an air pressure collection pipe (not shown in the figure). In this embodiment, the air duct is an axially telescopic corrugated hose, and the air pressure collection pipe is a hose with a diameter smaller than that of the air duct. The detection box includes a box body 2, and a box cover 1 that can be flipped open or closed is connected to the front end of the box body 2. The rear end of the box cover 1 is connected to the box body through a lock (or zipper connection).

[0028] The upper end of the box body 2 is detachably connected with a partition plate 4 by screws. The partition plate 4 divides the inner cavity of the detection box into an upper space and a lower space. The upper space is formed between the upper end of the partition plate 4 and the box cover 1. In the lower space, there are a box body ventilation duct 17 and a mounting plate 18. The mounting plate 18 is horizontally fixed to the bottom of the box body. The mounting plate 18 is located at the front side of the lower space, and the box body ventilation duct 17 is located at the rear side of the mounting plate 18. The box body ventilation duct 17 is a straight duct with an axis extending in the left-right direction. The left end of the box body ventilation duct is fixedly penetrated through the left side wall of the box body, and the right end of the box body ventilation duct is fixedly penetrated through the right side wall of the box body.

The right end of the box body ventilation duct is an air inlet 15 communicating with the atmosphere, and the left end of the box body ventilation duct is an air outlet 16 for connecting with the air duct. The air outlet 16 protrudes leftward outside the left side wall of the box body for facilitating connection with the air duct.

[0030] A flow sensor 12 extending in the front-rear direction and connected to the left end of the box body ventilation duct is arranged on the left side of the mounting plate. A motor drive board 14 for controlling the axial flow fan is installed on the mounting plate. A pressure sensor 11 and a power supply module are also installed on the mounting plate 18.
