Technical Field
The utility model relates to an air quality detects technical field, specifically is an air sampler business turn over gas port connects.
Background
The air quality detection means detecting whether the air quality is good or not. The quality of the air reflects the concentration of pollutants in the air. Air pollution is a complex phenomenon, and the concentration of air pollutants at a particular time and place is influenced by many factors. The size of the emission of man-made pollutants from stationary and mobile pollution sources is one of the most important factors affecting the air quality, including the exhaust from vehicles, ships, airplanes, industrial production emissions, residential and heating, waste incineration, etc. The development density of cities, landforms, weather and the like are also important factors influencing the air quality.
With the improvement of the quality of life and the improvement of environmental protection and health consciousness of people, the indoor air quality is more and more concerned and Chinese. The updating of the indoor air detection equipment corresponding to the row is also a day-to-day difference, and the types of the indoor air detection equipment are huge and the functions of the indoor air detection equipment are different. The detection process of the air detection equipment mostly needs to sample air firstly, and then the sampled air can be detected according to different detection principles. However, most of the air sampling devices have exposed air inlet and outlet hoses (the housing of the air sampling device is directly provided with holes, and the ends of the air inlet and outlet hoses are directly placed in the holes of the housing), which is not beautiful and dustproof, and is easy to cause the air inlet and outlet hoses to fall off and shift.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art's not enough, provide an air sampler business turn over gas port and connect, install in air sampler's shell trompil department, for air sampler advance, give vent to anger the hose and provide a reliable strong point, prevent to advance, give vent to anger the hose and shift in use or transportation, drop. Meanwhile, the air sampler can be fixed on the shell of the air sampler in a threaded or bonding mode, and good sealing performance can be provided for the air sampler, so that dust is prevented from entering the shell.
In order to achieve the above purpose, the utility model adopts the technical scheme that: an air inlet and outlet port connector of an air sampler is arranged on a shell of the air sampler, is connected with an air inlet hose and an air outlet hose, and comprises a connector end, a free end and a fixed cylinder body, wherein the connector end is connected with one end of the fixed cylinder body; the free end is positioned in the fixed cylinder body, and an open groove is formed between the free end and the inner wall of the fixed cylinder body; and a positioning boss is arranged at the end part of the fixed cylinder body.
The interface end and the free end are respectively of a tubular structure; the axial lines of the interface end and the free end are superposed and communicated with each other.
The front end of the interface end is provided with a leather hose connecting groove.
The cross section of the tubular structure of the free end is circular, quadrangular or hexagonal.
And the outer circular surface of the fixed cylinder is provided with external threads.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
The air sampling device is arranged at the opening of the shell of the air sampling device, provides a reliable supporting point for the air inlet and outlet hoses of the air sampling device, and prevents the air inlet and outlet hoses from shifting and falling off in the use or transportation process. Meanwhile, the air sampler can be fixed on the shell of the air sampler in a threaded or bonding mode, and good sealing performance can be provided for the air sampler, so that dust is prevented from entering the shell.
