[0022] As Figures 1-4 Indicated, the utility model embodiment subway tunnel internal environment safety monitoring device can include first frame 10 and second frame 20.

[0023] First frame 10 can include first frame body 11 and mounting piece 12, wherein first frame body 11 is fixed on the mounting surface. Mounting piece 12 is detachable and mounted on first frame body 11, and mounting piece 12 is used to install monitoring equipment 60.

[0024] Second frame 20 can include second frame body 21 and limiting piece 22, wherein second frame body 21 is detachable and mounted on first frame body 11, one side of first frame body 11 is formed with annular groove 111 near mounting piece 12, one side of second frame body 21 is provided with positioning block 213, positioning block 213 is detachable and slidably arranged in annular groove 111, and positioning block 213 and annular groove 111 are detachably connected. With the cooperation of positioning block 213 and annular groove 111, the assembly position of second frame body 21 on first frame body 11 can be effectively determined, and then the precise installation of second frame body 21 and first frame body 11 at diversified and orderly angles is promoted.

[0025] Second frame body 21 is provided with moving rail 212, and the outer side of mounting piece 12 is formed with circular ring 121 matched with moving rail 212. One side of moving rail 212 is open near first frame body 11.

[0026] It should be noted that the positioner 22 described in this embodiment can flexibly regulate the position of the mounting member 12 on the moving rail 212. The positioner 22 can include a screw rod 221, a first baffle 222 and a second baffle 223, wherein the screw rod 221 is movably arranged on the second frame body 21 and is arranged along the direction of the moving rail 212, one end of the screw rod 221 penetrates through the second frame body 21 and is sleeved with a fixing bolt 50, the first baffle 222 and the second baffle 223 are respectively located on the two symmetrical sides of the mounting member 12 and are connected by the connecting plate 40, the first baffle 222 is threadedly sleeved outside the screw rod 221, and the second baffle 223 is rotationally connected with the connecting plate 40.
