Abstract
The utility model relates to a ventilating and noise-reducing louver with an improved structure, which includes a frame body, wherein a louver structure formed by blinds is embedded in an inner cavity of the frame body. The ventilating and noise-reducing louver is characterized in that the blinds are inverted-V-shaped bodies formed by pressing noise-reducing cotton, and the blinds are embedded in the frame body through the two side end surfaces thereof. The ventilating and noise-reducing louver solves the problems of the prior art that the existing metal blinds barrier partially the air current from passing, reduce the noise-reducing effect, and produce self vibration to cause secondary noise pollution.
Description
Technical field
The utility model relates to a kind of ventilating noise reduction shutter that has improved structure, and it belongs to ventilating noise reduction device class.
Background technology
The ventilating noise reduction shutter is the settings commonly used of occasions such as power machine room, compressor room, counter formula power unit, and the ventilating noise reduction shutter of prior art comprises a frame body mostly; Said frame body inner chamber is embedded with louvre blade and forms shutter, and said louvre blade comprises the metal mold body of hollow, and said metal feature becomes reverse V-shaped; Offer some through holes on the surface of said metal mold body, in the hollow die cavity of said metal mold body, be filled with quieter material; The problem that prior art exists is, although its surface of metal mold body offers some through holes, but still the quieter material that passes through in it of air-flow is caused certain obstacle; Directly influenced erasure effect, moreover metal mold body influence itself forms self-vibration; Produce the secondary noise pollution, obviously prior art has further improved necessity.
Summary of the invention
The purpose of the utility model is to provide a kind of ventilating noise reduction shutter that has improved structure, to overcome the problem that prior art exists.
A kind of ventilating noise reduction shutter that has improved structure of the utility model; Comprise frame body; Said frame body inner chamber is embedded with louvre blade and forms shutter; It is characterized in that said louvre blade is the inverted V-shape body that the cotton compacting of noise reduction forms, said louvre blade passes through its two side end face inlay cards in said frame body.
This ventilating noise reduction shutter that has improved structure of the utility model has been cancelled the metal mold body in the louvre blade of prior art, for this reason, has improved air communication and has crossed the cotton resistance of noise reduction, has promoted erasure effect.
As further improvement, the reverse V-shaped angle of said louvre blade is the 45-75 degree, and the vertical vertical section width of said louvre blade is the 50-70 millimeter, and said louvre blade is spaced apart the 60-75 millimeter, and test shows has best erasure effect in this scope.

Fig. 1 is a kind of ventilating noise reduction shutter front view that has improved structure that the utility model preferred embodiment is provided.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is a kind of ventilating noise reduction shutter stereogram that has improved structure that the utility model preferred embodiment is provided.
Among each figure:
1 is frame body;
2 is louvre blade;
Angle;
H is vertical vertical section width;
D is the louvre blade interval.
The specific embodiment
A kind of ventilating noise reduction shutter and accompanying drawing thereof that has improved structure that below will combine the utility model preferred embodiment to provide is described further the utility model.
A kind of ventilating noise reduction shutter that has improved structure that the utility model preferred embodiment provides; Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3; Comprise frame body 1; Said frame body 1 inner chamber is embedded with louvre blade 2 and forms shutter, it is characterized in that the inverted V-shape body that said louvre blade 2 forms for the cotton compacting of noise reduction, and said louvre blade 2 passes through its two side end face inlay cards in said frame body 1.In this preferred embodiment, the reverse V-shaped angle of said louvre blade 2 is 60 degree, and the vertical vertical section width H of said louvre blade is 70 millimeters, and said louvre blade interval D is 70 millimeters.
In sum; A kind of ventilating noise reduction shutter that has improved structure of the utility model comprises frame body, and said frame body inner chamber is embedded with louvre blade and forms shutter; It is characterized in that said louvre blade is the inverted V-shape body that the cotton compacting of noise reduction forms; Said louvre blade through its two side end face inlay cards in said frame body, the metal mold body that the utility model has solved the louvre blade that prior art exists to air-flow pass through cause certain obstacle, reduced erasure effect; And influence forms self-vibration, the problem of generation secondary noise pollution.
The above is merely the specific embodiment of the utility model.But the utility model protection domain is not limited thereto.Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement; All should be encompassed within the protection domain of the utility model, therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
Claims (2)
