Abstract
The invention discloses a louver with the noise lowering function. The louver comprises a louver body in which sound absorbing sponge and a plurality of blades are arranged, the sound absorbing sponge is installed on the inner side of the louver body, the blades are arranged on the portion, on the two sides of the sound absorbing sponge, of the louver body in parallel, the included acute angle between the joints of the blades and the louver body and the louver body is 60-75 degrees, and the blades are of a bent structure bent towards the sound absorbing sponge. According to the louver with the noise lowering function, due to the fact that the sound absorbing spine adheres to the inner side of the louver body and the bent blades are obliquely arranged on the portion, at the two ends of the sound absorbing sponge, of the louver body, when noise passes the blades, the noise can be refracted to the sound-absorbing sponge along the blades, after a large amount of energy of the noise is absorbed by the sound-absorbing sponge, the energy of the noise is very low, and therefore it can be guaranteed that the noise is low in energy when reflected again by the sound absorbing sponge, and therefore a good noise lowering effect is achieved.
Description
Technical field
The present invention 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 object of the invention is to overcome the above-mentioned deficiency of prior art and provide a kind of shutter with decrease of noise functions, it has, and structure is simple, the good advantage of noise reduction.
Technical scheme of the present invention 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 present invention is: the bending angle of described blade is 130 ~ 150 °.
The present invention further technical scheme is: described forms are that sheet metal bending becomes upper and lower and has certain flange " Ω " shape structure.
The present invention 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 present invention compared with prior art has following features: the shutter with decrease of noise functions provided by the invention passes through inside forms, be bonded with sound-absorbing sponge, 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 invention is further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
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, 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 75 °, and the noise of coming in from blade can be ensured all to be refracted on sound-absorbing sponge, and blade is the bending structure to the bending of sound-absorbing sponge direction.
Forms are that sheet metal bending becomes upper and lower " Ω " shape structure having certain flange; Forms are that stainless steel material processing and fabricating forms, and have good soundproof effect.
The bending angle of blade is 145 °, ensures that the noise of coming in from blade is all refracted on sound-absorbing sponge further; Blade is that stainless steel material processing and fabricating forms, and has good soundproof effect.
Sound-absorbing sponge is fixed on inside forms by bonding mode, and structure is simple, fastness is higher.
Operating principle of the present invention and using method are: 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, noise its energy had when sound-absorbing sponge 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.
