Description

TECHNICAL FIELD

[0001] The utility model relates to the field of alarm installation, specifically relates to a mounting structure of indoor combustible gas alarm. BACKGROUND

[0002] The working principle of the combustible gas alarm is that the sensor in the alarm detects the combustible gas in the air, such as natural gas or liquefied gas, and triggers a signal when the concentration exceeds the preset safety threshold, the device starts the sound and light alarm, the buzzer rings and the indicator light flashes, so as to remind the user of the leakage of combustible gas. At present, the installation of indoor combustible gas alarm is generally to paste 3M tape on the back of the alarm and fix it directly on the flat wall, or to fix the alarm on the wall with expansion screws. The former is not firm and the alarm is easy to fall off after long-term use. The alarm for natural gas is generally installed at a position of several tens of centimeters away from the ceiling. When the alarm falls off, it may be damaged and scrapped. Although the expansion screw fixing method is more firm, it is inconvenient to operate and easy to damage the expansion screw interface when checking, repairing or replacing the alarm. Therefore, it is necessary to design an installation structure to solve the problem of unstable installation and frequent disassembly, and the installation structure should not affect the normal operation of the combustible gas alarm.
