The invention relates to a lifting type seal air volume cover. The cover comprises an air volume cover body, a pedestal and a signal processing device. An elevating device is arranged under the air volume cover body, and comprises a base. A first rotation shaft is arranged in the middle position of the base. Two first support rods and two second support rods are arranged on two ends of the first rotation shaft. A first connection rod is arranged on the end part of each first support rod. A second connection rod is arranged on the end of each second support rod. The ends of the first connection rods and the ends of the second connection rods are connected with a second rotation shaft. A third rotation shaft is arranged between the first support rods. A first cylinder is connected to the third rotation shaft and to the base. A fourth rotation shaft is arranged between the second support rods. A second cylinder is connected to the fourth rotation shaft and to the base. A guiding device is arranged between the pedestal and the base. Via the elevating device, the air volume cover can be mechanically elevated and lowered; tests can be finished without manual holding; and precision of the tests is increased.
