Abstract

The invention discloses a manual air door sealing device, and relates to an air door sealing device. A sealing barrier strip is arranged on an air door body; a plurality of rotating shafts penetrate the sealing barrier strip in parallel; one end of each rotating shaft is connected with a transmission connecting rod, and the other end of each rotating shafts is connected with a handle support seat; the handle support seat is connected with a handle; and the rotating shafts positioned in the sealing barrier strip are respectively connected with blades. The device has a simple structure, can be conveniently and flexibly used, and can improve the sealing performance of the air door obviously and prevent air leakage.

Description

technical field [0001] The invention relates to a sealing device for a damper. Background technique [0002] It is a very common technology to use a damper on the exhaust duct to adjust the air volume of the duct to open and close the duct. At present, a single-piece manual damper is more common, and the shaft is driven to rotate through the turning handle, so that the blades on the shaft are deflected to open and close the damper. But such dampers require ample space to use and are unusually cumbersome to operate. Contents of the invention [0003] The object of the present invention is to provide a manual damper sealing device with simple structure, flexible and convenient use, which can significantly improve the sealing performance of the damper and prevent air leakage. [0004] A manual damper sealing device, the air door body is provided with a sealing bar, and several rotating shafts are inserted parallel to the sealing bar, one end of the rotating shaft is connect...
