Description

Technical Field

[0001] The utility model relates to the technical field of gas analyzers, in particular to a portable volatile organic gas analyzer. Background Art

[0002] Gas analyzers are process analysis instruments that measure gas composition. In many production processes, especially those involving chemical reactions, automated control based solely on physical parameters such as temperature, pressure, and flow is often insufficient. Due to the wide variety of gases being analyzed and the diverse analytical principles, there are many different types of gas analyzers. Commonly used ones include thermal conductivity gas analyzers, electrochemical gas analyzers, and infrared absorption analyzers.

[0003] However, when using existing portable volatile organic gas analyzers, the gas analyzer is usually placed directly in a tool box after use. However, when other tools in the tool box come into contact with the gas analyzer, friction will occur on the surface of the gas analyzer, which will have a certain impact on the service life of the analyzer body. At the same time, the analysis head for analyzing organic gas outside the gas analyzer protrudes from the outside, and the analysis head will inevitably come into contact with other objects, and the analysis head is easily damaged, which will have a certain impact on the data of organic gas analysis. Therefore, a portable volatile organic gas analyzer is provided. Utility Model Content

[0007] Specifically, a slide groove is provided inside the shell A, and a slide plate connected to the fixed block is slidably connected to the inside of the slide groove. A magnetic block A is fixed to the outside of the slide plate by screws, and a magnetic block B magnetically connected to the magnetic block A is fixed to the inside of the slide groove by screws.

[0008] By adopting the above technical solution, when the fixed block is moved out of the shell A to protect the analysis head, the magnetic block A on the external slide of the fixed block and the magnetic block B installed in the slide groove are magnetically connected, thereby facilitating the fixing of the fixed block.

[0009] Specifically, the driving blocks are symmetrically welded inside the support rods, and the housing A is provided with connecting grooves for the driving blocks to slide.

[0010] By adopting the above technical solution, when the support rod drives the shell B to move, the driving block outside the support rod slides in the connecting groove provided in the shell A, thereby improving the stability of the support rod driving the shell B to move.

[0011] Specifically, the inner size of the through hole matches the outer size of the limiting block.

[0012] By adopting the above technical solution, when the limit block enters the through hole opened on the surface of the shell A, the inner side of the through hole matches the outer side of the limit block, thereby improving the stability of the limit block fixation.

[0013] Specifically, the inner size of the connecting groove matches the outer size of the driving block.

[0014] By adopting the above technical solution, when the driving block slides in the connecting groove opened in the housing A, the inner side of the connecting groove matches the outer side of the driving block, thereby improving the stability of the driving block moving in the connecting groove.
