The invention discloses an air quality collection device for safety engineering, and belongs to the field of air collection, the air quality collection device comprises a collection box, a base is arranged at the bottom of the collection box, supporting rods are rotatably connected to the two sides of the bottom end of the base, a groove is formed in the bottom end of each supporting rod, and a threaded groove is formed in one side of each groove; first threaded rods are arranged in the grooves and the threaded grooves correspondingly, bottom rods are fixedly arranged at the bottom ends of the first threaded rods, and a mounting plate is connected to one side of each bottom rod through a damping rotating shaft. According to the air quality collecting device for safety engineering, a supporting rod is rotationally unfolded and rotates to pass through a first threaded rod, so that a plurality of bottom rods can be attached to the ground, due to the fact that a threaded groove is in threaded transmission with th
