Description

Technical Field

[0001] The utility model relates to the technical field of blinds, in particular to a double-layer high-efficiency, silent and waterproof blind. Background Art

[0002] As an important part of a building, blinds not only have the function of ventilation, but also provide sufficient natural light for the room. Existing blinds usually use screws to fix the blades during installation, which results in cumbersome installation procedures and high labor costs. At the same time, after the blinds are installed, the blades are interlocked and overlapped with each other, and there is no air permeable gap in the middle. On the one hand, the ventilation efficiency is reduced, resulting in insufficient indoor and outdoor air exchange. On the other hand, due to the lack of air permeable gap, rainwater accumulates on the blades instead of flowing down smoothly, increasing the risk of rainwater infiltrating into the room. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a double-layer, high-efficiency, silent and waterproof blinds, which allows air circulation by installing a breathable and water-removing gap between the blade arrays, and at the same time adopts a blade clamp to connect the blade with a single piece of buckle to achieve the purpose of adjusting the tightness of the blade and quick installation, thereby solving the problems in the prior art.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solution: In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solution: A double-layer, high-efficiency, silent and waterproof shutter, comprising at least two groups of blade arrays spaced apart along the air entry direction, and a breathable and water-permeable gap is installed between each of the blade arrays to allow air circulation, and the blades in each group of the blade arrays are spaced apart along the up and down directions, and each blade is respectively arranged on the inner side of the shutter outer frame through a blade clamp.

[0005] Compared with the prior art, the utility model has the following beneficial effects:

[0006] 1. Compared with the prior art which usually uses screws to fix the blades, resulting in cumbersome installation procedures and high labor costs, the utility model uses an aluminum alloy blade clamp to directly clamp the blade on the clamp, thereby achieving the advantage of saving labor costs;

[0007] 2. Compared with the conventional double-layer blades in the prior art, the blades are interlocked and overlapped, and there is no air-permeable and water-falling gap in the middle, which causes the problem of reduced ventilation efficiency and rainwater accumulation and leakage. The utility model proposes an air-permeable and water-falling gap design. On the one hand, rainwater passes through the second layer of blade array and falls to the lower frame of the outer frame under the action of gravity and is discharged to the outside. On the other hand, after repeatedly changing the direction of the airflow, a large amount of air passes through the gap, and the air can be temporarily stored and taken out, and slowly sent into the room under the action of the external wind.

[0008] 3. In order to further collect and discharge a small amount of rainwater entering the room and achieve the purpose of indoor cleanliness, the utility model proposes to fix a water collection groove connected to the drainage groove at the bottom of the outer frame, and make it protrude from the bottom edge of the outer frame to form a continuous waterproof structure.

DETAILED DESCRIPTION

[0016] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0017] like Figure 1 As shown, as the first embodiment of the utility model, the utility model provides a technical solution: a double-layer high-efficiency silent waterproof shutter, comprising at least two groups of blade arrays spaced apart along the air entry direction, the customized first-layer blade array 2 is located on the outside, directly facing the wind, rain and dust from the outside, the second-layer blade array 3 is located on the inner side of the first-layer blade array, and cooperates with the first-layer blade array 2 to form an air-permeable and water-falling gap 9. It can be understood that, due to the interlocking and overlapping of blades between ordinary double-layer blades in the prior art, there is no air-permeable and water-falling gap 9 in the middle, which causes the problems of reduced ventilation efficiency and rainwater accumulation and leakage. Therefore, the proposed air-permeable and water-falling gap 9 is an air and rainwater diversion space between the two layers of blades (the first-layer blade array 2 and the second-layer blade array 3), the purpose of which is to allow rainwater to flow downstream and be discharged outdoors, while allowing air circulation. The blade units in each group of blade arrays are spaced apart along the up and down directions, and each blade unit 4 is respectively arranged on the inner side of the shutter outer frame 1 through a blade clamp 5 to form a multi-layer protection and filtration system.

[0018] In one embodiment of the present invention, the blade unit 4 includes a waterproof guide arc plate 44 and at least one waterproof sand blocking plate, wherein the waterproof guide arc plate 44 is fixedly arranged on the inner side of each waterproof sand blocking plate, and each waterproof sand blocking plate surrounds the waterproof guide arc plate 44 to form a cavity layout structure with an arc-shaped cross-section, which is used to form a continuous filtering path. It should be noted that, since there is a problem in the prior art that when the blade size exceeds 1 meter, the middle part is prone to deformation and the strength is not high, in specific implementation, it is preferred to use a group of three waterproof sand blocking plates to form a blade unit, that is, Figure 2As shown, the first waterproof sand blocking plate 41, the second waterproof sand blocking plate 42 and the third waterproof sand blocking plate 43 are stacked to form a continuous filtering path. At the same time, the waterproof guide arc plate 44 is located on the same inner side of the three protective plates and is connected to the arc cavity 45 to form a complete guide and noise reduction system, which not only improves the efficiency of air filtration, but also optimizes the guidance of airflow, reduces wind force and noise control. The first waterproof sand blocking plate 41, the second waterproof sand blocking plate 42 and the third waterproof sand blocking plate 43 are arranged in sequence on the outer circumferential surface of the waterproof guide arc plate 44 at equal intervals according to a preset curvature to form an effective air guide path. Each waterproof sand blocking plate is connected to the waterproof guide arc plate 44 by welding and / or bolts and / or snaps to form an integral structure. The purpose is to greatly enhance the rigidity of the entire blade assembly, effectively resist bending and twisting caused by wind force, and reduce the deformation risk of large-sized blades. Each waterproof sand-blocking board has a streamlined structure to better guide airflow and reduce resistance, and the surface of each waterproof sand-blocking board is evenly coated with an anti-static coating to reduce the adhesion of sand and dust.

[0019] Based on the above technical concept, Figure 3 As shown, it can be understood that when strong wind passes through the shutter frame 1, due to the design of the arc-shaped cavity 45, the air speed will decrease after entering the cavity, thereby reducing the noise caused by the wind and achieving a silent effect. At the same time, the three waterproof sand-blocking plates filter the air step by step to prevent the invasion of moisture and dust, and keep the indoor environment clean. The arc-shaped design helps to guide the airflow and facilitate air circulation. When the wind speed is relatively high, when the air passes through the first layer of blade array 2, at this time, a breathable water-falling gap 9 design is adopted. The rainwater is blocked by the second layer of blade array 3 to reduce its speed. Under the action of gravity, it falls into the water collection groove 6 of the lower frame of the shutter frame 1 and is discharged to the outside. The air is slowly sent into the room, so that the sound of "whistling" wind will not be generated, reducing the noise. At the same time, due to the optimization of the guidance of the airflow, it directly plays a role in reducing wind force and keeping the blades from deformation.

[0020] like Figure 4As shown in the figure, as an embodiment of the utility model, since the prior art generally uses screws to fix the blades, which causes the installation process to be cumbersome and the labor cost to be high, it is proposed to use an aluminum alloy blade clamp 5 to directly clamp the blade single piece 4 on the clamp to achieve the advantage of saving labor cost. It should be noted that the blade clamp 5 includes a clamp body 51, a clamping portion 52 and a fixing portion 53, wherein the clamp body 51 is fixedly installed on the inner side of the shutter outer frame 1, and a plurality of L-shaped or hook-shaped fixing portions 53 are extended along the edge or side of the clamp body 51, and the fixing portion 53 is close to and surrounds the outer edge surface of the blade single piece 4, which is used to ensure To ensure that the blade piece 4 does not move or fall off during operation, the clamping part 52 is arranged at the end of the fixing part 53 and is snap-connected with the blade piece 4 to adjust the tightness of the blade piece 4 and quickly install it. The fixing part 53 is close to and surrounds the other end of the outer edge of the blade piece 4, and is provided with a drainage groove 54 that fits tightly with the clamp body 51 to discharge moisture accumulated on the blade piece 4. The water collecting groove 6 is connected to the drainage groove 54 and protrudes from the bottom edge of the shutter frame 1 to collect and discharge a small amount of rainwater entering the room. At the same time, a rubber strip or silicone is set at the connection between the water collecting groove 6 and the shutter frame 1 for sealing.

[0021] Based on the above technical concept, in order to ensure a tight fit between the blade piece 4 and the blade clamp 5, as well as appropriate spacing between the blade pieces 4, the clamping portion 52 can be embedded in or installed at the end of the fixing portion 53 through a set of screws or nuts or sliders, thereby allowing the user to adjust the tightness of the blade piece 4 and quickly install it as needed.

[0022] In one embodiment of the utility model, in order to prevent rats, insects, and birds from entering the room and to prevent sand and dust, a stainless steel wire mesh 8 or a dustproof net is also installed between the shutter outer frame 1 and the second layer blade array 3. At the same time, in order to achieve a further sealing effect, a rubber strip 7 is applied to the connection between the stainless steel wire mesh 8 and the shutter outer frame 1 for sealing and fixing.

[0023] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
