Ventilation pipeline connecting structure for electromechanical engineering

The utility model provides a ventilation pipeline connecting structure for electromechanical engineering. The ventilation pipeline connecting structure for electromechanical engineering comprises a first pipeline; the second pipeline is arranged on one side of the first pipeline; the four fixing blocks are fixedly mounted on the inner wall of the first pipeline; the four mounting grooves are formed in one sides of the corresponding fixing blocks respectively; the four supporting blocks are fixedly mounted on the inner wall of the second pipeline; the four mounting blocks are slidably mounted in the corresponding mounting grooves respectively, and one ends of the four mounting blocks extend out of the four mounting grooves respectively and are fixedly connected with one sides of the corresponding supporting blocks; and the four first cavities are formed in the corresponding fixing blocks respectively. The ventilation pipeline connecting structure for electromechanical engineering has the advantages of being co
