Airflow guide cover

Abstract

An airflow guide cover includes a main body and a panel. The main body includes a top wall, two sidewalls extending down from opposite sides of the top wall, and an airflow guiding channel bounded by the top wall and the sidewalls. The airflow guiding channel includes two opposite openings. The panel is rotatably connected to a top of the main body above one of the openings. The panel is capable of being rotated between a first position where the panel is supported on the top wall, and a second position where the panel partly covers the opening, to adjust airflow through the airflow guide cover.

1 . An airflow guide cover, comprising:
 a main body comprising a top wall, two sidewalls extending down from opposite sides of the top wall, and an airflow guiding channel bounded by the top wall and the sidewalls, the airflow guiding channel comprising two opposite openings;   a panel rotatably connected to a top of the main body above one of the openings, wherein the panel is capable of being rotated between a first position where the panel is supported on the top wall and a second position where the panel partly covers the opening.   
     
     
         2 . The airflow guide cover of  claim 1 , wherein two blocks respectively extend up from upper portions of ends of the sidewalls towards the opening, a first pivot pole is connected between the blocks, and a second pivot pole is rotatably connected to the first pivot pole, the panel is connected to the second pivot pole. 
     
     
         3 . The airflow guide cover of  claim 2 , wherein a pivot hole is defined in an upper portion of each block above the top wall, the first pivot pole comprises a first shaft extending through the pivot holes, and two stop members respectively and detachably engaging with opposite ends of the first shaft and abutting against outer sides of the blocks. 
     
     
         4 . The airflow guide cover of  claim 3 , wherein the second pivot pole comprises an elongated plate, two pivot portions respectively extend outwards from opposite ends of the plate and contact inner sides of the blocks, a pivot hole is defined in each pivot portion, the first shaft extends through the pivot holes of the blocks and the pivot portions, to rotatably connect the second pivot pole to the first pivot pole and the blocks. 
     
     
         5 . The airflow guide cover of  claim 4 , wherein two fixing portions respectively extend inwards from the opposite ends of the plate, the second pivot pole further comprises a second shaft, a flange defining a through hole longitudinally extends from a side of the panel, the second shaft extends through the through hole of the flange, and opposite ends of the second shaft are detachably engaged in the corresponding fixing portions. 
     
     
         6 . The airflow guide cover of  claim 5 , wherein a middle section of the second shaft is rotatably received in the through hole of the flange. 
     
     
         7 . The airflow guide cover of  claim 1 , wherein a hook is formed on a top of each sidewall adjacent to the opening, and extends towards the opposite sidewall, when the panel is located on the first position, opposite ends of the panel are respectively latched by the hooks. 
     
     
         8 . The airflow guide cover of  claim 1 , wherein a slot is defined in a middle portion of the end of each sidewall towards the opening, two latches respectively extend from opposite ends of the panel, when the panel is located on the second position, the latches respectively engage in the slots of the sidewalls.
