Abstract
The utility model discloses a sound-deadening insulation ventilation opening, comprising an outer frame, a guide vane and a fixed clamp; the rear end of the guide vane is connected with one end of a sound-deadening insulation sheet made of sound-deadening insulation material; the other end of the sound-deadening insulation sheet is connected with the outer frame through the fixed clamp; and the sound-deadening insulation sheet is internally provided with a reinforcement rib. The sound-deadening insulation ventilation opening is capable of absorbing and insulating noises outside, preventing noises from entering the room or transmitting the indoor noises outside and transmitting the noises of adjacent rooms, and has the characteristics of good sound-deadening insulation effect, simple structure and low cost.
Description
Technical field
The utility model belongs to technical field of construction and decoration materials, especially relates to a kind of noise elimination sound insulation ventilating opening.
Background technology
Outside the building on wall or the interior wall, be typically provided with the air port of ventilation usefulness, can play rainproof, dustproof effect, avoid dust etc. to enter air pipeline, cause outdoor and indoor environmental pollution, present air port does not have the noise reduction silencing means, because install on the wall in the air port, the noise of indoor and outdoor can be propagated mutually, can form noise pollution.
Summary of the invention
The purpose of this utility model is to improve the deficiency of prior art and provides a kind of and absorb isolated ambient noise, avoids in the noise inlet chamber or room noise passes to the noise transmission of outdoor and adjacent room, the noise elimination sound insulation ventilating opening that the noise elimination soundproof effect is good, simple in structure, cost is low.
The purpose of this utility model is to realize like this, a kind of noise elimination sound insulation ventilating opening, by housing, guide vane and fixedly bail form, the rear end that is characterized in guide vane connects an end of the noise elimination sound insulation sheet that quieter material makes, and the other end of noise elimination sound insulation sheet is connected with housing by fixing bail.
In order further to realize the purpose of this utility model, the cross section that can be described noise elimination sound insulation sheet is circular-arc.
In order further to realize the purpose of this utility model, can be to be provided with reinforcement in the described noise elimination sound insulation sheet.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is by housing, guide vane and fixedly bail form, the rear end of guide vane connects an end of noise elimination sound insulation sheet, the other end of noise elimination sound insulation sheet passes through fixedly, and bail is connected with housing, enter the sound of noise elimination sound insulation ventilating opening like this, can be absorbed by the noise elimination sound insulation sheet that the quieter material of inside, air port is made, avoided noise to propagate the noise pollution that produces by ventilating opening, simultaneously since noise elimination sound insulation sheet and guide vane link together, the position relative fixed of noise elimination sound insulation sheet and guide vane has guaranteed that noise elimination sound insulation sheet absorbs the effect of noise; The Cross section Design of noise elimination sound insulation sheet is an arcuation, makes like this to form repeatedly reflection in the noise transmission process between adjacent noise elimination sound panel, improves to absorb noise result; Be provided with reinforcement in the noise elimination sound insulation sheet, guaranteed the shape invariance of noise elimination sound insulation sheet, prolonged service life, guaranteed to absorb the effect of noise.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
Fig. 3 is another structural representation of the present utility model.
The specific embodiment
Embodiment 1, a kind of noise elimination sound insulation ventilating opening, with reference to Fig. 1, be on housing 1 inwall, to pass through the fixedly two ends of bail 3 fixed guide vanes 2, one end of the noise elimination sound insulation sheet 4 that the inboard rear end connection quieter material of guide vane 2 is made, the other end of noise elimination sound insulation sheet 4 is connected with housing 1 by fixing bail 3, and the cross section of noise elimination sound insulation sheet 4 is a V-type in the present embodiment, and this constitutes a kind of structure of the present utility model.
Embodiment 2, and a kind of noise elimination sound insulation ventilating opening with reference to Fig. 2, is on the basis of embodiment 1, and the cross section of noise elimination sound insulation sheet 4 is circular-arc, and other and embodiment 1 are identical.
Embodiment 3, and a kind of noise elimination sound insulation ventilating opening with reference to Fig. 3, is on the basis of embodiment 2, is provided with reinforcement 5 in the noise elimination sound insulation sheet 4, and reinforcement 5 is wrapped in quieter material inside, and other and embodiment 2 are identical.
