Description

Technical Field

[0001] The utility model belongs to the technical field of gas concentration monitors, and particularly relates to an installation structure of a gas concentration monitor. Background Technique

[0002] A gas concentration monitor is an important device for detecting the gas concentration in the environment. Its working principle is usually based on different detection technologies, such as catalytic combustion type and infrared absorption type, etc. The catalytic combustion type monitor measures the concentration by using the heat generated by the combustion of gas under the action of a catalyst, and the infrared absorption type determines the concentration by detecting the absorption degree of gas to infrared rays with a specific wavelength;

[0003] The installation structure of the gas concentration monitor includes an installation bracket for fixing the monitor body, usually made of metal, with sufficient strength and stability. It can be a wall-mounted bracket fixed on the wall;

[0004] Currently, in the prior art, it is generally installed on a horizontal plane or a vertical plane. The outer shell of the gas concentration monitor is installed in cooperation with screws, etc. Due to different installation environments, the gas concentration monitor in cooperation with screws is only suitable for installation on horizontal and vertical planes, and cannot be conveniently installed on a cylindrical pipeline or a columnar support, resulting in certain defects in the installation structure of the gas concentration monitor;

[0005] To solve the above problems, an installation structure of a gas concentration monitor is proposed in this application. Content of the Utility Model
