Abstract
The utility model provides a shutter with function of making an uproar is fallen, includes the window form, is equipped with in the window form to inhale sound sponge and a plurality of blade, inhales the sound sponge and installs in the inboard of window form, and blade parallel mount is on the window form of inhaling sound sponge both sides, and the blade is 60~75 with the tie point department of window form with the acute angle that the window form presss from both sides, and the blade is to inhaling the structure of buckling that sound sponge direction is buckled. The utility model provides a shutter with function of making an uproar is fallen is through having the sound of inhaling sponge inboard bonding of window form, and the blade of buckling is placed in the slope on the window form of inhaling sound sponge both ends, when the noise passes through the blade, can make the noise along the blade direction reflected inhale the sound sponge on, the noise is inhaled behind a large amount of energy of sound spongy absorbing, its energy that has is very low, will guarantee like this that noise its energy that has when inhaling the reecho of sound sponge is very low, thereby reach better the noise reduction effect.
Description
Technical field
The utility model relates to a kind of shutter, particularly a kind of shutter with decrease of noise functions.
Background technology
Electric fixtures operationally, a large amount of heats can be produced, higher in order to ensure the application life of equipment, often can ventilate at its workplace installation ventilation shutter, but equipment operationally can send certain noise, its noise is easily passed by common shutter, causes very adverse influence to staff and surrounding environment.
CN101109264A discloses a kind of sound-deadening louver, the shutter of this invention is made up of multiple blade bodies of the face tilt relative to wall body, each blade body is in formation anechoic chamber, inside, and form opening in side relative to the ventilation opening of wall body, first and second reflecting plate that multiple edge part from this opening extends to anechoic chamber and in the inside of blade body is installed respectively, first reflecting plate is curve form, second reflecting plate is flat shape, although this invention can reach noise reduction, but this invention complex structure, there is the space of improving further in noise reduction.
Summary of the invention
The purpose of this utility model be overcome prior art above-mentioned deficiency and a kind of shutter with decrease of noise functions is provided, it has, and structure is simple, the good advantage of noise reduction.
The technical solution of the utility model is: a kind of shutter with decrease of noise functions, comprise forms, sound-absorbing sponge and some blades is provided with in described forms, described sound-absorbing sponge is arranged on the inner side of forms, described blade is installed in parallel on the forms of sound-absorbing sponge both sides, folded by the tie point place of blade and forms and forms, acute angle is 60 ~ 75 °, and blade is the bending structure to the bending of sound-absorbing sponge direction.
The further technical scheme of the utility model is: the bending angle of described blade is 130 ~ 150 °.
The utility model further technical scheme is: described forms are that sheet metal bending becomes upper and lower and has certain flange " Ω " shape structure.
The utility model further technical scheme is: folded by the tie point place of described blade and forms and forms, acute angle is 75 °.
Further, the bending angle of described blade is 145 °.
Further, described forms are that stainless steel material processing and fabricating forms.
Further, described blade is that stainless steel material processing and fabricating forms.
Further, described sound-absorbing sponge is fixed on inside forms by bonding mode.
The utility model compared with prior art has following features: what the utility model provided has the shutter of decrease of noise functions by being bonded with sound-absorbing sponge inside forms, and the blade of bending is placed with in the forms surface thereof at sound-absorbing sponge two ends, when noise is by blade, noise can be made to be refracted on sound-absorbing sponge along direction blade, after noise is absorbed a large amount of energy by sound-absorbing sponge, its energy had is very low, will ensure that noise its energy had when sound-absorbing sponge is reflected again is very low like this, thus reach good noise reduction.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the elevation of Fig. 1;
Fig. 3 is A-A sectional view in Fig. 1.
Detailed description of the invention
As shown in drawings: a kind of shutter with decrease of noise functions, it is characterized in that: comprise forms 1, sound-absorbing sponge 2 and some blades 3 is provided with in forms 1, sound-absorbing sponge 2 is arranged on the inner side of forms 1, blade 3 is installed in parallel on the forms 1 of sound-absorbing sponge 2 both sides, the tie point place of blade 3 and forms 1 is 75 ° with acute angle folded by forms 1, and the noise of coming in from blade 3 can be ensured all to be refracted on sound-absorbing sponge 2, and blade 3 is the bending structure bent to sound-absorbing sponge 2 direction.
Forms 1 become upper and lower " Ω " shape structure having certain flange for sheet metal bending; Forms 1 form for stainless steel material processing and fabricating, have good soundproof effect.
The bending angle of blade 3 is 145 °, ensures that the noise of coming in from blade 3 is all refracted on sound-absorbing sponge 2 further; Blade 3 forms for stainless steel material processing and fabricating, has good soundproof effect.
Sound-absorbing sponge 2 is fixed on inside forms 1 by bonding mode, and structure is simple, fastness is higher.
Operating principle of the present utility model and using method are: when noise is by blade 3, noise can be made to be refracted on sound-absorbing sponge 2 along blade 3 direction, after noise is absorbed a large amount of energy by sound-absorbing sponge 2, its energy had is very low, noise its energy had when sound-absorbing sponge 2 is reflected again very low (direction of transfer of noise is as arrow indicated direction in accompanying drawing 3) will be ensured like this, thus reach good noise reduction; If have the occasion of requirements at the higher level can install this kind of shutter in two sides to noise reduction, its noise reduction is better.
Claims (8)
1. one kind has the shutter of decrease of noise functions, it is characterized in that: comprise forms, sound-absorbing sponge and some blades is provided with in forms, sound-absorbing sponge is arranged on the inner side of forms, blade is installed in parallel on the forms of sound-absorbing sponge both sides, folded by the tie point place of blade and forms and forms, acute angle is 60 ~ 75 °, and blade is the bending structure to the bending of sound-absorbing sponge direction.
