Provided is a connecting rod transmission mechanism with a non-pressure air door for a mine. A plane linkage mechanism is arranged inside an upper transverse frame of the non-pressure air door. The plane linkage mechanism is mainly composed of rockers, a connecting rod, rocker fulcrum shafts and a connecting rod fulcrum shaft. The rockers are arranged at the two ends of the plane linkage mechanism and are connected with the rocker fulcrum shafts. The connecting rod is connected with the two rockers as a whole through the connecting rod fulcrum shaft. The rocker fulcrum shafts penetrate through rotational components arranged at the two ends of the upper transverse frame of the non-pressure air door and fix the plane linkage mechanism inside the upper transverse frame of the non-pressure air door to form a built-in connecting rod transmission mechanism. When one door leaf of two door leaves of the non-pressure air door is opened or closed, the other door leaf can be simultaneously opened or closed in an opposite direction through the built-in connecting rod transmission mechanism. The connecting rod transmission mechanism with the non-pressure air door for the mine has the advantages of being novel and practical in structure, flexible in opening, small in volume and occupying space, and suitable for being used in an underground coal mine.
