Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 to 4, the object of the present invention can be achieved by the following technical solutions: the utility model provides a gas alarm fixed mounting structure, includes alarm casing 1 and fixing base 2, alarm casing 2 includes casing 11 and lower casing 12, casing 12 is equipped with arch 121 down, 2 periphery sides of fixing base are equipped with fixed part 21, fixed part 21 include joint portion 212 and with protruding 121 corresponds the recess 211 that sets up, alarm casing 1 with fixing base 2 has counterpoint state and stationary state, alarm casing 1 changes into stationary state with fixing base 2 at counterpoint state relative rotation. When the alarm is installed, the alarm shell is firstly aligned in an alignment state and then fixed by turning into a fixed state through relative rotation. The clamping portion 212 is provided with protruding teeth, and the inner side of the protrusion 121 is provided with meshing teeth matched with the protruding teeth. The biting force between the protrusion 121 and the clamping portion 212 can be increased, the fixing strength between the lower shell 12 and the fixing base 2 is increased, and the assembling reliability and firmness are increased. The fixing base 2 is provided with a pressing rotating part 22. Be equipped with on lower casing 12 and hold holding tank 122 of fixing base 2, the holding tank 122 bottom is equipped with dodges breach 123, dodge breach 123 is located arch 121 below.
