[0026] A blasting safety protection device under this specific embodiment, such as Figure 1-4 As shown, a blasting safety protection device includes a protective plate 1, which protects workers performing mine blasting. The inner wall of the protective plate 1 is slidably connected to two extension plates 3 that slide axially toward the outside of the two ends of the base. The two extension plates 3 increase the area of the protective plate 1. One end of the two extension plates 3 is equipped with an adjustment mechanism for controlling the two extension plates 3 to slide toward the outside of the protective plate 1. One side of the protective plate 1 is rotatably connected to the bottom plate 2, and one side of the bottom plate 2 is equipped with a frame mechanism for connecting and supporting the bottom plate 2.

[0027] Through the above technical solution, the base plate 2 is placed on the ground, and the adjustment mechanism is started, so that the adjustment mechanism drives the two extension plates 3 to slide toward the outside of the protective plate 1, thereby increasing the area of the protective plate 1. At the same time, the frame mechanism can control one side of the protective plate 1 to flip at one end of the base plate 2, and adjust the angle of the protective plate 1, so as to facilitate the increase of the area of the protective plate 1 according to the mine blasting environment, thereby improving the safety of the blasting workers.

[0028] like Figure 1-4 As shown, two cone columns 4 are fixedly connected at both ends of the bottom of the base plate 2 to stabilize the base plate 2.

[0029] Through the above technical solution, the two cone columns 4 are driven into the ground to stabilize the bottom plate 2, making it convenient to stabilize the entire device.

[0030] like Figure 1-4As shown, the adjustment mechanism includes two adjusting links 5 rotatably connected to the two extension plates 3, and the other ends of the two adjusting links 5 are rotatably connected to a lifting plate 6 that drives one end of the two adjusting links 5 to move, and a clamping component for fixing the lifting plate 6 is installed on the inner wall of the lifting plate 6.

[0042] like Figure 1-4 As shown, the flip assembly includes a connecting rod 16 rotatably connected to one end of the protective plate 1, the other end of the connecting rod 16 is slidably connected to a connecting rod 2 17, the other end of the connecting rod 2 17 is rotatably connected to one end of the surface of the bracket 14, one end of the surface of the connecting rod 16 is threadedly connected to a fixing screw 18, and a flip groove for fixing the connecting rod 16 is provided on the surface of the connecting rod 2 17, and the fixing screw 18 is slidably connected in the flip groove.

[0043] Through the above technical solution, it is necessary to adjust the angle of the protective plate 1, rotate the fixing screw 18 to loosen the fixing screw 18, and then make the connecting rod 16 slide on the inner wall of the connecting rod 2 17, and at the same time, the fixing screw 18 slides in the flipping groove, and the distance between the connecting rod 16 and the connecting rod 2 17 is adjusted to drive the protective plate 1 to flip the angle, and rotate the fixing screw 18 so that one end of the fixing screw 18 presses against the surface of the connecting rod 2 17 to fix the connecting rod 16 and the connecting rod 2 17.
