[0002] Explosion-proof combustible gas detectors are important industrial safety equipment, widely used in places where flammable, explosive or toxic gases exist, such as petroleum, chemical, pharmaceutical and other fields. Its main function is to monitor the concentration of combustible gas on site, convert the concentration signal into a digital signal, and transmit it to the gas alarm controller in the safe area, thereby preventing fire and explosion accidents caused by combustible gas.

[0003] Existing explosion-proof combustible gas detectors have some defects during installation. During the installation process, due to the special design and complex installation requirements of explosion-proof combustible gas detectors, the installation steps are cumbersome and require professional technicians to operate. In addition, some detectors may need to be installed in difficult-to-reach locations, which increases the difficulty and time of installation and is not convenient for later maintenance. For this reason, we propose an explosion-proof combustible gas detector. Utility Model Content

[0020] 2. When installing the explosion-proof combustible gas detector, the explosion-proof gas detector is placed on the surface of the mounting plate, and then the mounting rod in the mounting device is pulled.

The explosion-proof gas detector is pressed and fixed by the elastic force of the spring, and then connected and fixed by the magnets at both ends of the mounting rod, so that it is further installed and fixed. The simplified installation steps can improve work efficiency, reduce the time required for installation, and reduce installation costs.
