Description

Technical Field

[0001] This utility model relates to the field of metal louvered doors and windows, and in particular to a louvered window. Background Technology

[0002] Louvers are typically installed on building windows, air conditioning unit inlets, and ventilation unit inlets. The size of the louvers is matched to the size of the window or air inlet.

[0003] Existing patents, such as (CN102606050B), disclose a type of louver where the blades are arranged vertically side by side, forming a ventilation channel between adjacent blades to ensure ventilation. However, there is usually no other horizontal obstruction between adjacent blades, making it difficult to form a seal between the blades. This allows rainwater to enter the room through the gap between the blades under the action of wind, resulting in poor rain protection of the louver. Utility Model Content

[0004] The purpose of this invention is to provide a louver to solve the problems existing in the prior art, thereby improving the ventilation effect and significantly enhancing the rainproof function of the device.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides a louver, including a frame, a first slat, and a second slat. The frame has at least one mounting window, which extends through the frame in a first direction. Both the first slat and the second slat are fixedly connected to the inner wall of the mounting window. The first slat includes a first inclined plate and a first barrier plate, and the second slat includes a second barrier plate. A second slat is disposed between two vertically adjacent first slats. Both the first barrier plate and the second barrier plate are vertically arranged and perpendicular to the first direction. The first barrier plate and the second barrier plate have a first ventilation gap in the first direction. The first barrier plate has a first blocking portion, a first connecting portion, and a second blocking portion distributed sequentially along the vertical direction. Each first inclined plate is fixed on the first connecting portion and located on the side of the first barrier plate closer to the outside. The first inclined plate gradually tilts downward in the direction away from the first barrier plate. The second barrier plate and each of the two adjacent first slats have a second ventilation gap in the vertical direction.

[0007] In some embodiments, the second barrier plate is closer to the outside in the first direction than the first barrier plate.

[0008] In some embodiments, a second inclined plate is fixedly provided on the side of the second barrier plate away from the first barrier plate. The second barrier plate has a third blocking portion, a second connecting portion and a fourth blocking portion distributed vertically in sequence. Each of the second inclined plates is fixed on the second connecting portion and located on the side of the second barrier plate closer to the outside. The second inclined plate gradually tilts downward in the direction away from the second barrier plate. The first inclined plate and the second inclined plate are parallel.

[0009] In some embodiments, the edge of the first inclined plate is flush with the edge of the second inclined plate.

[0010] In some implementations, the distance between two adjacent first barrier plates is projected onto the plane of the outer perimeter of the frame, corresponding to the position of one of the second barrier plates.

[0011] In some embodiments, a partition plate is fixedly disposed within the frame, and the partition plate divides the installation window into a first installation window and a second installation window.

[0012] In some embodiments, the first barrier plate, the first inclined plate, and the second barrier plate are all fixedly connected to the inner sidewall of the mounting window by bolts.

[0013] In some embodiments, the frame is provided with a plurality of protrusions on its outer wall facing outward. The protrusions gradually slope downward away from the second barrier plate. The protrusions are arranged sequentially at intervals in the vertical direction, and each of the first inclined plate and the second inclined plate is provided with one of the protrusions. The length of the protrusion is equal to the length of the second inclined plate and the length of the first inclined plate extending out of the frame.

[0014] In some embodiments, the louvers are made of aluminum alloy.

[0015] In some embodiments, the first inclined plate and the first barrier plate have a first included angle, and the second inclined plate and the second barrier plate have a second included angle, wherein the first included angle and the second included angle are equal and both are greater than or equal to 60° and less than 90°.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] This utility model provides a louver, which is provided by setting a first blade and a second blade, both of which are fixed to a frame.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides a venetian blind, such as Figure 1-2 As shown, the device includes a frame 1, a first blade 3, and a second blade 4. The frame 1 has at least one mounting window that extends through the frame 1 in a first direction. Both the first blade 3 and the second blade 4 are fixedly connected to the inner wall of the mounting window. The first blade 3 includes a first inclined plate 6 and a first barrier plate 5. The second blade 4 includes a second barrier plate 7. A second blade 4 is disposed between two vertically adjacent first blades 3. Both the first barrier plate 5 and the second barrier plate 7 are vertically arranged and perpendicular to the first direction. The first barrier plate 5 and the second barrier plate 7 have a first ventilation gap 11 in the first direction. The first barrier plate 5 has a first shielding part, a first connecting part, and a second shielding part distributed sequentially in the vertical direction. Each first inclined plate 6 is fixed on the first connecting part and located on the side of the first barrier plate 5 closer to the outside. The first inclined plate 6 gradually tilts downward in the direction away from the first barrier plate 5. The second barrier plate 7 has a second ventilation gap 12 between it and each of the two adjacent first blades 3 in the vertical direction. This application provides a first blade 3 and a second blade 4, both fixed to a frame 1. The first blade 3 includes a first inclined plate 6 and a first barrier plate 5. The first inclined plate 6 is fixed to the middle of the first barrier plate 5 and gradually tilts downward. The second blade 4 includes a second barrier plate 7. A second barrier plate 7 is provided between two vertically adjacent first barrier plates 5, and the first barrier plates 5 and the second barrier plates 7 are parallel and have a ventilation channel in the horizontal direction. Therefore, the louver ensures the ventilation effect of the louver by staggering the adjacent first barrier plates 5 and the second barrier plates 7, and by having a gap between the adjacent first barrier plates 5 and the second barrier plates 7. The first barrier plate 5 is divided into a first blocking part, a first connecting part, and a second blocking part. There is a second blocking part, a second barrier plate 7, and a first blocking part between two adjacent first inclined plates 6. Therefore, a horizontal barrier is formed between two adjacent first inclined plates 6, thereby ensuring the ventilation effect of the louver while effectively preventing rainwater from entering the room from between the two adjacent blades, thus improving the rainproof function of the louver.

[0025] In some embodiments, the second barrier 7 is closer to the outside than the first barrier 5 in a first direction. Because the second barrier 7 is positioned closer to the outside, when rain falls, it can first contact and block most of the rainwater, allowing the rainwater to flow outwards along its surface, reducing the possibility of rainwater directly splashing onto the first barrier 5 and entering the room.

[0026] In some embodiments, a second inclined plate 8 is fixedly disposed on the side of the second barrier plate 7 away from the first barrier plate 5. The second barrier plate 7 has a third blocking portion, a second connecting portion, and a fourth blocking portion arranged vertically in sequence. Each second inclined plate 8 is fixed to the second connecting portion and located on the side of the second barrier plate 7 closer to the outside. The second inclined plate 8 gradually tilts downward in the direction away from the second barrier plate 7, and the first inclined plate 6 and the second inclined plate 8 are parallel. The second inclined plate 8 can guide rainwater to flow to the outside better, and from an aesthetic point of view, the parallelism of the first inclined plate 6 and the second inclined plate 8 makes the structure of the louvers more regular and symmetrical, presenting a simple and beautiful visual experience.

[0027] In some embodiments, the edge of the first inclined plate 6 is flush with the edge of the second inclined plate 8. The flush edges of the first inclined plate 6 and the second inclined plate 8 ensure that rainwater does not drip onto the louvers and does not fall onto the lower louvers, leaving watermarks and stains. At the same time, the flush edges of the inclined plates make the louvers look neater and more uniform, enhancing the overall visual appeal of the louvers.

[0028] In some embodiments, the distance between two adjacent first barrier plates 5, projected onto the plane of the outer perimeter of the frame 1, corresponds to the position of a second barrier plate 7. The first barrier plates 5 and the second barrier plates 7 form an interlaced blocking structure. For rainwater to enter the room, it must first pass over the first barrier plate 5 and then over the second barrier plate 7, increasing the difficulty of rainwater entry. Furthermore, the second shielding part, the second barrier plate 7, and the first shielding part form a complete vertical shielding between two adjacent first inclined plates 6, improving the rainproof effect of the louvers without affecting ventilation.

[0029] In some embodiments, a partition plate 2 is fixedly installed inside the frame 1, dividing the installation window into a first installation window and a second installation window. The partition plate 2 can increase the overall structural strength of the frame 1, making the frame 1 more stable when subjected to external forces, reducing the risk of deformation or damage to the frame 1 due to external forces, and enhancing structural stability.

[0030] In some embodiments, the first barrier plate 5, the first inclined plate 6, and the second barrier plate 7 are all fixedly connected to the inner wall of the installation window by bolts. The bolt connection operation is relatively simple, and construction personnel can quickly fix each component in the designated position using ordinary tools, shortening the installation time and improving work efficiency. Moreover, when replacing components, the first barrier plate 5, the first inclined plate 6, and the second barrier plate 7 can be easily removed from the inner wall simply by unscrewing the bolts, which is convenient for operation and use.

[0031] In some embodiments, the frame 1 has multiple protrusions on its outer wall facing outwards. These protrusions gradually slope downwards away from the second barrier plate 7, and are arranged sequentially at intervals along the vertical direction. Each of the first inclined plate 6 and the second inclined plate 8 has a corresponding protrusion. The length of the protrusion is equal to the length of the second inclined plate 8 and the length of the first inclined plate 6 extending out of the frame 1. Viewed from the side, the protrusions effectively conceal and hide the first inclined plate 6 and the second inclined plate 8, making the overall structure of the blinds more harmonious and unified in appearance, creating an orderly visual effect and enhancing the overall aesthetics of the blinds.

[0032] In some implementations, the blinds are made of aluminum alloy. Aluminum alloy has good corrosion resistance and is not easy to rust. Even in humid environments, it can maintain good performance. In addition, aluminum alloy has high strength and can withstand certain external impacts without easily deforming. It can effectively resist the effects of natural factors such as strong winds, maintain the integrity of the blinds, and extend their service life.

[0033] In some embodiments, the first inclined plate 6 and the first barrier plate 5 have a first included angle 9, and the second inclined plate 8 and the second barrier plate 7 have a second included angle 10. The first included angle 9 and the second included angle 10 are equal, and both are greater than or equal to 60° and less than 90°. When the included angle is within the range of greater than or equal to 60° and less than 90°, the inclined plate can provide a suitable flow slope for rainwater, allowing rainwater to flow smoothly down the surface of the inclined plate under the action of gravity, thereby reducing the risk of rainwater seeping into the room.

[0034] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
