The present application belongs to the field of industrial detection equipment and facilities, and proposes an industrial environment sampling detection device, which comprises a double-path atmospheric sampler, the double-path atmospheric sampler comprises an instrument main body and two sampling tubes, the bottom of the instrument main body is provided with a rotating arm, the end of the rotating arm away from the instrument main body is provided with a suspension arm, the top end of the suspension arm is used to be nested with a sampling port of an industrial tower, the suspension arm is provided with a sampling cover at the position opposite to the sampling port, the sampling cover is provided with at least two inlet openings used to cooperate with the sampling tubes, the suspension arm is provided with a clamping mechanism which is slidably matched with the suspension arm, and the clamping mechanism and the suspension arm are both provided with lug ears which are matched with the sampling tubes. The present application has the advantages of reasonable design, simple structure, high space utilization, convenience in sending the sampling tubes into the sampling port, and improvement in instrument safety and detection sealing performance.

This invention belongs to the field of construction project cost management display technology, specifically a construction project cost management display device. It includes a main board with a display screen embedded in its center. Two sets of display panels are symmetrically mounted on the main board, and two sets of suspension shafts are symmetrically connected to the display panels. Rollers are spun onto the suspension shafts. A limiting frame is provided at the upper end of the main board, which limits the rollers, and the rollers rotate around the limiting frame. Pulling the two sets of display panels in opposite directions separates them, thereby opening the display screen. Because the display screen is embedded in the center of the main board, the risk of the display screen being bumped is reduced. Furthermore, during the pulling process, the display panels drive the suspension shafts and rollers to move together, and the rollers rotate along the limiting frame. The cooperation between the rollers and the limiting frame guides the movement of the display panels. The rotation of the rollers not only makes the movement of the display panels smoother but also reduces wear caused by the movement, thus increasing the service life of the device.
