[0001] The invention relates to the technical field of oxygen analyzers, in particular to oxygen analyzers. Background Art

[0002] Oxygen analyzer is an industrial online process analysis instrument, which is widely used in the detection of oxygen concentration in mixed gas in heating furnaces, chemical reaction vessels, underground wells, industrial nitrogen production and other occasions. In industrial production, oxygen analyzer can be used to monitor and control the oxygen concentration in reactors, combustion systems, air separation oxygen production, chemical processes, etc. in real time to ensure production safety and product quality. In chemical processes, monitoring oxygen concentration can prevent explosions or other safety accidents.

[0003] Existing oxygen analyzers need to connect the oxygen supply pipeline to the oxygen analyzer, and the interface of the oxygen analyzer is set on the outer shell of the device. It is easy to cause damage to the device interface during the use of the oxygen analyzer, which can easily cause gas to leak from the interface of the oxygen analyzer, which will cause errors in the detection results. After the oxygen supply pipeline is connected, it is necessary to maintain a stable connection between the device and the pipeline. However, the existing oxygen analyzer fixes the pipeline through the interface, and the interface of the device is prone to loosening after long-term use, which will cause gas leakage at the interface and affect the analysis results.
