Device for opening and closing air conditioner air duct through support rotating clamping and filter screen opening and closing

Abstract

The invention discloses a device for opening and closing an air conditioner air duct through support rotating clamping and filter screen opening and closing. The device structurally comprises a protective shell, a movable frame, a baffle block and an opening and closing rotating device. The baffle block is positioned on the front end surface of the protective shell and is fixedly welded with the protective shell through a right-angled plate body to form an integrated structure. A front support rod is driven by an inner rotating plate to be overturned and movably rotated inside under the limitof a roller frame; a front folding frame can be overturned in a sliding groove in an annular manner through a support rod; and the opening and closing of a filter screen, arranged inside a concave block, of a threaded plate are movably adjusted through the threaded plate, so that the air conditioner air duct can be opened and closed through the bidirectional opening and closing of the filter screen, and the damage of airflow to an opening and closing structure can be prevented.

Description

technical field [0001] The invention relates to the field of air-conditioning machinery, in particular to an air-conditioning air duct opening and closing device that is tightly closed and opened by a filter screen that is locked and rotated by a bracket. Background technique [0002] The air-conditioning duct is an active aisle used to transport and disperse the hot and cold airflow inside the duct, so as to distribute it to the place where it is needed. At the same time, the bracket-shaped louver structure in front of the aisle is usually used to match the extension and contraction of the bracket to make the louver structure Toggle to realize the opening and closing of the air-conditioning aisle, and there is usually a rectangular filter structure inside, but in this way: [0003] 1. When the opening and closing work is performed, the mechanical structure of the front-end louver structure is moved by the internal bracket movement. The flow rate of the external air volume a...

Under long-term exposure, after the outer mechanism is sealed, one end of the filter will still be exposed to the airflow, which will easily make the internal Premature saturation of the filter, resulting in waste of the filter
