Abstract
The utility model discloses a ventilation and noise reduction curtain which comprises a plurality of slender curtain blades. The section of each curtain blade is dovetail-shaped, each dovetail-shaped curtain blade is divided into two layers, the outer layer of each dovetail-shaped curtain blade is a hard material layer, a sound absorption material layer is arranged on the surface of one side of each hard material layer, the slender curtain blades are equidistantly and parallelly arranged side by side, and the head of each dovetail-shaped curtain blade is placed corresponding to the tail of the corresponding adjacent dovetail-shaped curtain blade and extends into the tail of the corresponding adjacent dovetail-shaped curtain blade by a certain distance. Sound is blocked by the curtain blades and is absorbed by sound absorption materials, so that an effect of reducing noise is achieved, and the ventilation and noise reduction curtain can realize ventilation, light transmission and sight blocking effects.
Description
[technical field]
The utility model relates to curtain motor, especially relates to a kind of can ventilate and can the noise reduction curtain.
[background technology]
The traffic noise problem of disturbing residents is a global difficult problem, and present technique is intended to crack this difficult problem.Curtain is the daily necessities of generally using in the daily life, and general curtain has cloth curtain or these curtain of venetian blind type can not blocking noise, and glass window can printing opacity, sound insulation, but can't breathe freely again.Can printing opacity but block vision is ventilated, and can reduce the curtain of noise, be that people expect always.
[utility model content]
Technical problem to be solved in the utility model is can ventilate and can reduce the noise curtain for the transport solution noise problem of disturbing residents provides a kind of.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of ventilation noise reduction curtain is provided, comprise some elongated curtain blades, the cross section of described curtain blade is swallow-tail form, the swallow-tail form curtain blade divides two-layer, skin is hard material layer, and one deck sound-absorbing material layer is set on the hard material layer, and several elongated curtain blade equidistant parallels are placed side by side, wherein the head of swallow-tail form places and stretches into the afterbody certain distance of swallow-tail form corresponding to the afterbody of swallow-tail form, and the angle angular range on two limits of swallow-tail form head is between 60 °-120 °.
Further improvement in the technical proposal is: the track that the two ends of described elongated curtain blade are provided with pulley and match.
Further improvement in the technical proposal is: some elongated curtain blades cover whole window opening, are provided with anti-leak-stopping acoustic seal frame around the window opening.
The beneficial effects of the utility model are: after the utility model ventilation noise reduction curtain is installed on the window, can significantly reduce traffic noise, and can guarantee good ventilation effect.Solved better traffic noise this world-famous puzzle that disturbs residents.

[specific embodiment]
See also Fig. 1 to 4:
A kind of ventilation noise reduction of the utility model curtain, comprise some elongated curtain blades 1, the cross section of described curtain blade 1 is swallow-tail form, the swallow-tail form curtain blade divides two-layer, skin is hard material layer 2, the hard material layer surface arranges one deck sound-absorbing material layer 3, several elongated curtain blade 1 equidistant parallels are placed side by side, wherein the head 4 of swallow-tail form places and stretches into the afterbody certain distance D of swallow-tail form corresponding to the afterbody 5 of swallow-tail form, and the angle angular range on two limits of swallow-tail form head is between 60 °-120 °.Therefore light cannot directly pass through, and people's sight line can't be directly by playing the effect of curtain.The propagation of sound is straightline propagation when not stopping, when running into obstacle or refraction, the reflection of sound wave occur, the afterbody certain distance D of swallow-tail form is placed and stretched into to the afterbody 5 of swallow-tail form, sound can't directly pass through, reflect, reflex time, sound wave is absorbed by the sound-absorbing material layer 3 in the swallow-tail form curtain blade, thereby the continuation that greatly reduces sound is propagated.
The track that the two ends of described elongated curtain blade are provided with pulley and match.Can conveniently move like this, be easy to open curtain.Certainly, this rail mounted structure is ubiquitous in the prior art, and this manual repeats no more.
Some elongated curtain blades are installed on the window, are provided with sealing frame 6 around the window opening, and around the sealing frame 6 and sound insulation setting between the forms, some elongated curtain blades cover sealing frames 6.Although reached soundproof effect between the swallow-tail form curtain blade, but always gapped around between swallow-tail form curtain blade and the forms, in order to make whole curtain reach soundproof effect, sealing frame is set around window, around the sealing frame and sound insulation setting between the forms, some elongated curtain blades cover sealing frame, thereby make whole forms possess soundproof effect.
Ventilation noise reduction curtain of the present utility model, comprise some elongated curtain blades, the cross section of described curtain blade is swallow-tail form, the swallow-tail form curtain blade divides two-layer, skin is hard material layer, hard material layer one side surface arranges one deck sound-absorbing material layer, several elongated curtain blade equidistant parallels are placed side by side, wherein the head of swallow-tail form places and stretches into the afterbody certain distance of swallow-tail form corresponding to the afterbody of swallow-tail form, sound is by the sound-absorbing with sound absorption material of stopping of curtain blade, reach the effect that reduces noise, ventilative, printing opacity but block vision.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
