Abstract
The invention relates to a ventilating fan orifice door, which comprises a door plate, an outer door frame, an inner door frame and an axial-flow fan. The door plate is hinged with the front surface of the outer door frame. A turn of metal edging strip is riveted on the internal side of the outer door frame. A rectangular dustproof screen plate is sealed at the full diameter of the boundary of the outer door frame and the inner door frame. The dustproof screen plate is connected with the axial-flow fan in the inner door frame through bolts and nuts. An automatic louver opening mechanism is fixedly arranged on the internal side of the outer door frame. The automatic louver opening mechanism can penetrate through a through hole at a corresponding position on the edge of the dustproof screen plate and is connected to a deflector rod on the side of the inner door frame. A louver at the air outlet of the inner door frame is fixedly connected onto the deflector rod. A touch head is installed on the side of the door plate. By adopting the technical scheme, the axial-flow fan is built in the ventilating fan orifice door and the automatic louver opening mechanism is used for opening and closing the louver. When the door plate is opened, the touch head loses pressure, a spring mechanism contracts and a connecting rod pulls the deflector rod to move downwards to open the louver; and reversely, the louver is closed.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to accompanying drawing 1 and 5, the embodiment of the present invention comprises:
A kind of ventilation fan aperture door, it comprises: door-plate 1, exterior door frame 2, interior doorframe 3 and axial flow blower 4; Described exterior door frame 2 is covered in interior doorframe 3 fronts that axial flow blower 4 is housed, and fastening by bolt 14; Described door-plate 1 is connected in exterior door frame 2 fronts by hinge 13; Touching 12 is equipped with on described door-plate 1 limit; The inner side edge riveted joint of described exterior door frame 2 has a circle metal hemming edge bar 5; The latus rectum place envelope that described exterior door frame 2 coordinates with interior doorframe 3 has the dustproof web plate 6 of rectangle; Dustproof web plate 6 centers are circular filter screen; Described dustproof web plate 6 is connecting the axial flow blower 4 of 3 li, interior doorframe by screw bolt and nut; The side edge of described exterior door frame 2 is fixed with automatic window mechanism 7; Described automatic window mechanism 7 comprises: touching piece 71, spring mechanism 73 and connecting rod 72; The touching of described touching piece 71 and correspondence position on described door-plate 1 limit 12 coordinates; Described touching piece 71 be "
