A quantitative sampling device for environment monitoring comprises a shell, the shell is of a hollow cylindrical structure, air suction pipes are installed on the left side and the right side of the shell respectively, a fixed air valve is installed at one end of each air suction pipe and fixed to the outer portion of the shell, and a fixing frame is installed at the other end of each air suction pipe and fixed to the outer portion of the shell. The fixing frame is fixed to the other side of the shell, and three movable fixing bases are further evenly arranged on the air suction pipe. According to the utility model, through the design of the sampling device, dust and dust pretreatment filtering work can be carried out on air in a building environment by utilizing a simple tool structure, and meanwhile, quantitative collection is carried out on the air in each storage bottle, so that a better sampling index is provided for subsequent air component detection; and the problem that the detection result is inaccu
