Abstract
A ventilation amortization window shutter comprising a rim and a shutter leaves. The rim comprises rim, top rim and bottom rim, peculiar in that the side rim, top rim, bottom rim, shutter leaves are connected with screw or rivet. Adopting such structure can effectively prevent deformation of side rim, top rim, bottom rim and shutter leaves, so the utility model can effectively prevent the top rim, bottom rim, shutter leaves and the two side rim from deforming.
Description
Technical field
The utility model relates to a kind of shutter, especially a kind of ventilating noise reduction shutter.
Background technology
Present prior art, as shown in Figure 1, a kind of ventilating noise reduction shutter comprises frame, louvre blade 3, frame is made of both sides frame 7, top margin frame 1, boundary frame area 2, top margin frame 1, boundary frame area 2, louvre blade 3 and 7 welding of both sides frame, louvre blade 3 is that Open Side Down dihedral, there is an inverted triangular-shaped grooves lower surface of top margin frame 1, and the upper surface of boundary frame area 2 is " people " font; Top margin frame 1 constitutes inlet channel 6, outlet passageway 5 with louvre blade 3, louvre blade 3 with boundary frame area 2 with louvre blade 3, louvre blade 3; Louvre blade 3, top margin frame 1, boundary frame area 2 have hollow, in fill out sound insulation, damping material 8, on the upper and lower wallboard 51,52 of outlet passageway 5 bloop 4 is arranged, louvre blade 3, top margin frame 1, boundary frame area 2 by 0.5 or the thick zinc-plated flat board of 0.8mm make; On the end plate 53 of outlet passageway 5 bloop 4 is arranged; On the wainscot 61 of inlet channel 6 bloop 4 is arranged.Existing problems are: when welding with both sides frame 7 owing to top margin frame 1, boundary frame area 2, louvre blade 3, produce heat energy, top margin frame 1, boundary frame area 2, louvre blade 3 are out of shape with both sides frame 7.
Summary of the invention
