Summary: | The utility model belongs to the technical field of environment detection, and particularly relates to a sampling tube for detecting ambient air, which comprises a base, an air pump and a limit ring are fixedly arranged at the top of the base, a sampling tube is movably placed in the limit ring, the bottom of the sampling tube is fixedly communicated with an air inlet tube, and the air inlet tube is communicated with an air outlet. The top end of the air pump fixedly communicates with a connecting pipe, the top end of the connecting pipe fixedly communicates with a connector, and limiting grooves are formed in the inner walls of the two sides of the connector. The gas sampling device is reasonable in structural design, facilitates connection and disassembly of the gas pump and the sampling pipe, is convenient to use, facilitates sealing of the sampling pipe through cooperation of the upper partition plate, the lower partition plate, the upper through hole, the lower through hole, the upper spring and the seal |
