Atmospheric sampler

Abstract

The invention relates to an atmospheric sampler. The atmospheric sampler comprises a sampler body, a storage base fixedly mounted on the sample body and three folding supporting feet, each supportingfoot comprises a turnover rod and two frame-shaped rods, one ends of the supporting feet are connected with the storage base, the two ends of each turnover rod are rotatably connected with the two frame-shaped rods, the turnover rods and the frame-shaped rods are fixed through fixing mechanisms, the three supporting feet are reverse to each other to be inclined, the storage base is provided with astorage mechanism for storing the folded supporting feet, the turnover rods and the frame-shaped rods are fixed through the fixing mechanisms, the sampler body can be supported for sampling, meanwhile, the turnover rods and the frame-shaped rods can be folded, the folded supporting feet can be stored below the storage base through the storage mechanism, the sampler body and the supporting feet donot need to be additionally dismounted, and the effect of facilitating carrying of the sampler can be achieved.

Description

technical field [0001] The invention relates to the technical field of atmospheric sampling equipment, in particular to an atmospheric sampling instrument. Background technique [0002] Atmospheric sampler is an instrument or device that collects air pollutants or polluted air. It plays a very good role in the detection of harmful gases in the air and the environment. It is widely used in atmospheric environment monitoring, sanitation and epidemic prevention, labor protection, and scientific research. and other units. [0003] Existing, such as Chinese Patent Utility Model Patent Application Announcement No. CN208805397U discloses a precise and stable atmospheric sampler, which includes a sampler host, supporting feet and a tripod. The support boss is flush with the bottom of the support feet, and the upper end of the tripod is threaded with a connecting seat, and there are three sets of U-shaped connecting ears fixedly connected at evenly spaced intervals along the side wa...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: in order to ensure the comprehensive shape and accuracy of sampling, it is usually necessary to sample and measure the atmosphere in different regions. When the sampler is moved to other places, the main body of the sampler and the tripod need to be separated and stored , for relocation, the disassembly and assembly of the main body of the sampler and the tripod are troublesome, time-consuming and laborious, the relocation is not easy, and the efficiency of sampling work is reduced
