Exhaust gas detection device

Abstract

The invention discloses an exhaust gas detection device. The exhaust gas detection device comprises a lower box body, wherein a long groove is formed in an upper surface of the lower box body, a lifting assembly is arranged in the long groove and comprises a rotation lead screw, a first connection rod, a second connection rod and a support plate, a lower fixed block and an upper movable block arerespectively hinged with two ends of the first connection rod, a lower movable block and an upper fixed block are respectively hinged with two ends of the second connection rod, a detector is arrangedon an upper surface of the support plate, an exhaust gas collection box is connected with an air outlet end of the detector, push plates are arranged on an upper surface and a lower surface of the interior of the exhaust gas collection box in a sliding way, and piston push rods are arranged at the centers of rear surfaces of the push plates. The exhaust gas detection device is simple in structureand is convenient to carry; by arranging the lifting assembly, the height adjustment of the device can be achieved, and the operation comfortableness is ensured; and the exhaust gas collection box isarranged, exhaust gas after detection can be collected by pulling the piston push rods, and the collection effect is excellent.

Description

technical field [0001] The invention relates to the technical field of exhaust gas detection, in particular to an exhaust gas detection device. Background technique [0002] Exhaust gas contains a large amount of harmful substances. It is particularly important to detect the quantity and ratio of chemical components in exhaust gas for targeted treatment. [0003] However, most of the current exhaust gas detection devices are inconvenient to carry. During the exhaust gas detection process, the appropriate operating height cannot be adjusted according to the height of the user, and when the exhaust gas detection is performed, the detected exhaust gas cannot be collected well, resulting in The exhaust gas after the detection is discharged into the air, causing harm to the user, and has certain defects. [0004] To this end, we propose an exhaust gas detection device. Contents of the invention [0005] The invention provides a waste gas detection device, the purpose of which...
