Flue gas measuring chamber structure easy to maintain

The utility model relates to the technical field of flue gas detection equipment, in particular to an easy-to-maintain flue gas measurement gas chamber structure which comprises a base, a gas chamber bracket, a gas chamber shell, a reflecting mirror and a convex lens, the air chamber shell and the base are detachably connected, more preferably, the air chamber shell and the base are detachably connected through threads, and disassembly and assembly are more convenient; the reflecting mirror and the convex lens are mounted and fixed by arranging the air chamber bracket in the air chamber shell; meanwhile, the side wall of the gas chamber support is arranged to be of a hollowed-out structure, diffusion of smoke in the gas chamber is facilitated, under the condition that the gas chamber shell is easy to disassemble, the reflecting mirror and the convex lens can be exposed after the gas chamber shell is opened, wiping by workers is facilitated, and maintenance is simpler. The air chamber shell and the air chamber
