Technical Field

[0001] The utility model relates to the technical field of environmental gas sampling, and in particular to a green and environmentally friendly environmental gas sampling device. Background Art

[0002] A gas sampler is an instrument or device for collecting atmospheric pollutants or polluted atmosphere. There are many types of gas samplers. According to the collection object, they can be divided into gas samplers and particulate samplers; according to the place of use, they can be divided into environmental samplers, indoor samplers and pollution source samplers. In addition, there are gas samplers for special purposes, such as samplers that collect gas and particulate matter at the same time, and samplers that collect bacteria in the air. Among them, gas samplers used for environmental testing are mostly used in the field, so they are often equipped with a fixed frame to support and fix them. Therefore, a green and environmentally friendly environmental gas sampling device is used to sample the air.

[0003] Prior art includes a utility model with publication number CN213022501U, which discloses a gas sampler. The patent adopts an adjustment mechanism and a sampling assembly, wherein the adjustment mechanism includes a fixed block, a first connecting member, a first connecting rod, a second connecting member, a sleeve, a first threaded rod, a rotating member and a second connecting rod. The sleeve is fixedly arranged on the side of the fixed block, and the first threaded rod is threadedly connected in the sleeve. The sampling assembly includes a placement rack and an instrument body. The placement rack is fixedly arranged on the top of the first connecting rod, and the instrument body is arranged on the placement rack. The utility model device solves the problem that the fixed racks of gas samplers used for environmental detection currently mostly only have supporting and placing functions. When used in the field, the complex terrain will affect the placement angle of the sampler, the stability cannot be guaranteed, and it is inconvenient for users to operate.

[0004] In daily work, when the equipment is sampling air, there is a problem that when the user needs to collect air at a higher place, the collection head is difficult to collect air at a high place, making it difficult for the equipment to collect air at different heights. Utility Model Content
