The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to accompanying drawing 1 and 5, the utility model embodiment 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 inboard 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 "
?" shape, the through hole of its corner coordinates with rotating shaft 75 and is fixed in by fixed block 74 on the side edge of described exterior door frame 2, at described touching piece 71 ends, also by rotating shaft 75, is connecting described spring mechanism 73 and connecting rod 72; Described spring mechanism 73 comprises sleeve 732, spring 731, shrinking connecting-rod 730; Described shrinking connecting-rod 730 is divided into two-section: top connects described connecting rod 72 and touching piece 71, and bottom is fixed on exterior door frame by fixed block 74; Described connecting rod 72 connects described driving lever 8 through the through hole of described dustproof web plate 6 edge correspondence positions; One group of shutter is housed on described driving lever 8, and blade of louver window 9 relies on the rotating shaft of its center to be fixed on interior doorframe air outlet, and can freely rotate around the shaft; Described plectrum 8 upper and lower displacements can drive blade of louver window 9 rotation, thereby described shutter can moving up and down and carry out oneself folding with driving lever 8.
When axial flow blower needs work, door-plate is opened, and now spring mechanism clockwise rotates around rotating shaft with driving lever, and the rotation of driving lever drives blade of louver window and opens.Axial flow blower energising work; When axial flow blower quits work, door-plate cuts out, when door-plate is bonded to exterior door frame, touching head on door-plate contacts with the touching piece in exterior door frame, depresses the touching piece, along with the motion of door-plate, the touching piece is subject to the pressure of touching head, it is rotated counterclockwise around rotating shaft, and the resistance that the touching piece overcomes spring mechanism drives the driving lever motion, and shutter is closed.
A kind of ventilation fan of the utility model aperture door, adopt automatic window organization switch shutter.When door-plate is opened, the touching device loses pressure, and spring mechanism shrinks, and connecting rod pulls driving lever to move down, and opens shutter; Otherwise close shutter, be embedded with shock absorbing rubber, the noise in the time of can reducing the door-plate switch on edge cover strip simultaneously.And door-plate is inner-opening type, dustproof web plate is equipped with in inside, can effectively prevent dust, sand-proof, stops air pollution, practical reliable, very easily extensively promotes.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
