Abstract
The utility model provides a pair of noise elimination shutter, it has set firmly the protection network on the support, can prevent that bird, worm from getting into, is favorable to indoor sanitation, avoids by mosquito bites, because winged petiole piece both ends and support damping are rotated to be connected, can be with the vertical setting of winged petiole piece, can mutual butt between double -phase neighbour's the winged petiole piece, can play the effect that stops to sound, can also stop sleet simultaneously, can also be with winged petiole piece slope setting, the distance between the double -phase adjacent winged petiole piece is the biggest at this moment, can make indoor and outdoor air circulate each other, is convenient for change indoor air, set up in the bottom of winged petiole piece and place the perforation of inhaling the cotton layer of sound, the interior effect of playing the amortization in the cotton layer of sound of inhaling of perforating, the amortization gauge height reaches 25dB, has reduced indoor noise.
Description
Technical field
The utility model relates to a kind of noise reduction shutter.
Background technology
Noise reduction shutter is a kind of window structure of energy stress release treatment, but noise reduction shutter of the prior art design is unreasonable, and installation accuracy is high, and ventilation noise reduction is bad, can not effective anti-bird insect protected.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of and install simple, ventilation excellent noise reduction effect, can also the noise reduction shutter of anti-bird insect protected.
The utility model realizes like this, a kind of noise reduction shutter, comprise the rectangular support frame of a hollow, multi-disc from top to bottom and successively spaced oval wing blade is provided with in described support, described wing blade two ends are connected with described support damping rotary, described wing blade bottom surface all offers some perforation, is provided with the acoustical cotton layer for sound-absorbing in described perforation, and described wing blade side is provided with a protective screening be fixedly connected with described support.
Particularly, the aperture of described protective screening is 0.5mm ~ 1mm.
Particularly, the angle that the center line of described wing blade and vertical curve are formed is 10 ° ~ 80 °.
Particularly, the gross area of some described perforation and the area ratio of wing blade bottom surface are 23%.
Particularly, the thickness of described support is 250mm ~ 310mm.
A kind of noise reduction shutter that the utility model provides, it is installed with protective screening on support, can prevent bird, worm enters, and is conducive to indoor sanitation of environment, avoids by bite by mosquitos; Because wing blade two ends are connected with support damping rotary, wing blade vertically can be arranged, can mutually abut between two adjacent wing blades, the effect of stop can be played to sound, simultaneously can also stop sleet, wing blade can also be obliquely installed, the distance now between two adjacent wing blades is maximum, the air of indoor and outdoors can be made mutually to circulate, be convenient to change indoor air; Offer the perforation of placing acoustical cotton layer in the bottom of wing blade, the acoustical cotton layer in perforation plays the effect of noise reduction, and sound-damping qualities, up to 25dB, reduces indoor noise.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic diagram of the noise reduction shutter that the utility model provides.
Fig. 2 is the sectional view along A-A direction in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As depicted in figs. 1 and 2, the noise reduction shutter that the utility model embodiment provides, comprise the rectangular support frame 1 of a hollow, multi-disc from top to bottom and successively spaced oval wing blade 2 is provided with in support 1, wing blade 2 two ends are connected with support 1 damping rotary, wing blade 2 bottom surface all offers some perforation 21, and be provided with the acoustical cotton layer (not shown) for sound-absorbing in perforation 21, wing blade 2 side is provided with a protective screening 3 be fixedly connected with support 1.
Preferably, the aperture of described protective screening 3 is 0.5mm ~ 1mm.
Particularly, the angle that the center line of described wing blade 2 and vertical curve are formed is 10 ° ~ 80 °.
Particularly, the gross area of some described perforation 21 and the area ratio of wing blade 2 bottom surface are 23%.
Particularly, the density of described acoustical cotton layer is 48KG/ cubic meter.
Particularly, the thickness of described support 1 is 250mm ~ 310mm
The noise reduction shutter that the utility model provides, it is installed with protective screening 3 on support 1, can prevent bird, worm enters, and is conducive to indoor sanitation of environment, avoids by bite by mosquitos; Because wing blade 2 two ends are connected with support 1 damping rotary, wing blade 2 vertically can be arranged, can mutually abut between two adjacent wing blades 2, the effect of stop can be played to sound, simultaneously can also stop sleet, wing blade 2 can also be obliquely installed, the distance now between two adjacent wing blades 2 is maximum, the air of indoor and outdoors can be made mutually to circulate, be convenient to change indoor air; Offer the perforation 21 of placing acoustical cotton layer in the bottom of wing blade 2, the acoustical cotton layer in perforation 21 plays the effect of noise reduction, and sound-damping qualities, up to 25dB, reduces indoor noise.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
