Abstract
The utility model relates to a multifunction sound-absorbing louvre window curtain, comprising a curtain frame, a vane, a shaft, a clip hoop, a pulley, a guy cable and a shaft hole. The utility model can be widely used in places where sound insulation and noise elimination are needed, the utility model is characterized in that a vane of the louvre window is a hollow cavity comprising double-layer micro-perforated plates with finite sheet figure and bore diameter, and the appearance of the vane is of wedge absorber shape and simultaneously has the function of permeating light, ventilating and absorbing sound. After the vane is painted with ornament pictures, the decorative effect is better, and if the curtain is installed in the outdoor, the curtain has the action of canopy on a rainy day. The utility model can be produced solely and has the advantages of low cost, simple installation, convenient operation and maintenance and easy popularization.
Description
Affiliated technical field
The utility model relates to a kind of sun blind, on the door and window of the various buildings that can be widely used in sound insulation, eliminate the noise to require with printing opacity, decoration, ventilation, acoustically effective.
Background technology
Hospital, office, school and residential district near traffic route, cities and towns road, zone, downtown area or factory, noise people's work, studying and living, insulting physical and mental health.The central core of circulation that noise enters the house is a door and window, and existing sun blind play the effect of printing opacity, ventilation, sound insulation, but function is all single.The multifunctional curtain that designs printing opacity, decoration, ventilation and sound absorption good, easy to use, with low cost does not almost have.
The utility model provides a kind of multi-functional sound absorption sun blind.It is to utilize relevant knowledge in the acoustic theory, and as methods such as thin plate sound absorption, microperforated panel sound absorption, cavity resonance and damping material noise reduction sound, the above-mentioned technology of integrated use can be widened frequency of noise elimination, improves acoustic attenuation performance.This sun blind can reduce room noise, can keep the indoor natural ventilating ventilation again.
Summary of the invention
The purpose that the utility model relates to provides a kind of multi-functional sound absorption sun blind, and in order to overcome existing curtain ventilation and the single deficiency of sound insulation function, the utility model provides a kind of curtain, and this curtain is light and airing not only, and can also insulate against sound.
The multi-functional sound absorption sun blind of the utility model are made up of window frame, blade, rotating shaft, clip, pulley, drag-line and axis hole.The pelmet size requires according to building and designs, and the length of blade and sheet number are decided with the size of window frame.Blade by last slice, down sheet is bonded into the hollow cavity of wedge absorber shape with lateral plate, last slice with following sheet be microperforated panel, the imperforated thin plate of lateral plate; Rotating shaft is linear leaf and pass along the axis of sheet under the blade slightly, and two ends are fixed with clip, and rotating shaft is inserted in the axis hole of the pelmet left and right sides, and can freely rotate; The annular guy cable rounds is fixed on the pulley in pelmet centre position, and annular drag-line passes each blade microperforated panel successively, and each blade is fixed by upper and lower two knots of drag-line.Blade can be around the shaft adjusted in horizontal plane becomes 15 °～85 ° scope, for widening the sound absorption frequency, obtains maximum acoustically effective.Microperforated panel last slice aperture φ 0.50mm, perforated percentage 3%, the thick 0.5～1.0mm of sheet; Sheet aperture φ 0.20mm under the microperforated panel, perforated percentage 1.5%, the thick 0.5～1.0mm of sheet.
The beneficial effects of the utility model are, this curtain reduction room noise that can insulate against sound can keep the indoor natural ventilating ventilation again, can also printing opacity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. pelmets among the figure, 2. blade, 3. rotating shaft, 4. clip, 5. pulley, 6. drag-line, 7. axis hole.
The specific embodiment
A kind of multi-functional sound absorption sun blind, its feature comprise pelmet [1], blade [2], rotating shaft [3], clip [4], pulley [5], drag-line [6] and axis hole [7] device composition.Pelmet [1] size requires according to building and designs, and the length of blade [2] and sheet number are decided with the size of window frame [1].Its blade [2] be by last slice, down sheet and lateral plate are bonded into the hollow cavity of wedge absorber shape, last slice and following sheet be microperforated panel, the imperforated thin plate of lateral plate.Rotating shaft [3] slightly linear leaf [2] and along blade [2] down the axis of sheet pass, two ends are fixing with clip [4], rotating shaft [3] is inserted in the axis hole [7] of pelmet [1] left and right sides, and can freely rotate.Annular drag-line [6] is walked around the pulley [5] that is fixed on pelmet [1] centre position, and annular drag-line [6] passes each blade [2] microperforated panel successively, and each blade [2] is fixed by upper and lower two knots of drag-line [6].Blade [2] [3] is around the shaft adjusted in horizontal plane becomes 15 °～85 ° scope.
The multi-functional sound absorption louver lamina of the utility model [2] selects for use transparent flexible PVC plastics, polyethylene, polyurethane material to make, and blade is unpicked and washed conveniently.Experiment showed, that multi-functional sound absorption sun blind can reduce by 10～15 decibels of noises.
The multi-functional sound absorption sun blind of the utility model are gone up the air brushing decoration painting at blade [2] makes curtain have decoration function.This curtain is installed in outdoor, and the rainy day can be played the effect of awning.
The multi-functional sound absorption sun blind of the utility model, reasonable material, well-designed accomplishes that printing opacity, decoration, ventilation and sound absorption combine together, is a kind of multiple functional, cheap, working service convenience, is easy to popularize the renewal product of use.
