Description

Technical Field

[0001] This utility model relates to a screen wall louver, and more specifically, to an adjustable angle screen wall louver that combines ventilation and rain protection. Background Technology

[0002] Curtain wall louvers are an exterior wall system composed of numerous adjustable-angle horizontal or vertical louvers. Traditional curtain wall louvers are widely used in residential and commercial spaces requiring ventilation, but they often struggle to simultaneously provide both ventilation and rain protection. For example, the existing louvers disclosed in patent CN109113541A (Energy-Saving, Light-Transmitting, Ventilating, and Rainproof Louvers) primarily function as ventilation and decoration, while also providing some shading; however, they do not meet the rain protection requirement. To achieve rain protection, typical louvers require denser slats, which in turn reduces ventilation efficiency. Therefore, this application proposes an adjustable-angle screen wall louver to meet market needs. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adjustable angle screen blind, which is achieved through the following technical solution:

[0004] This utility model provides an adjustable angle screen wall louver, comprising: a plurality of louver blades, each of which is fixedly connected at both ends to a second strip via a first connector; each of the second strips is also rotatably mounted on the first strip via a first connector; the first strip is mounted parallel to the louver frame; and the second strip is rotatably connected to the louver frame via a second connector.

[0005] Each end of the louver is provided with at least two mounting mechanisms. The mounting mechanisms can cooperate with the first connecting member and allow the louver to be movably connected to the first strip, so that the louver can rotate relative to the first strip.

[0006] The actuating element is connected to the first strip through the first connector. By rotating the actuating element, the position of the first strip is adjusted, thereby adjusting the angle of the louvers.

[0007] The cross-section of the louvers is S-shaped at both ends, and there are certain gaps between multiple louvers to achieve ventilation. When two louvers rotate to the position shown in the attached instruction manual... Figure 3 At the angle shown, this achieves the requirement of rain protection.

[0008] Both the first strip and the second strip are made of aluminum strips, which are lightweight and have high strength.

[0009] There are two first strips, both arranged vertically; there are multiple second strips, which are connected to the first strips at intervals and fixed to the louver frame.

[0010] Both the first connector and the second connector are countersunk screws.

[0011] The louver frame adopts a segmented design, including an end frame and a side frame. The end frame is connected to the second strip through a second connector, allowing the second strip to rotate around the second connector as an axis. The second strip presses the first strip between the end frame and the second strip. There are two side frames, located on the indoor and outdoor sides of the louver respectively. The end frame is located at both ends of the side frame and is connected to both side frames. This design facilitates disassembly and transportation, and also makes it easy to install the louver.

[0012] Based on the above technical solution, the following technical effects can be achieved:

[0013] (1) The angle of the curtain wall louvers is adjustable;

[0014] (2) The requirements of ventilation and rain protection of the curtain wall should be taken into account. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. In the absence of conflict, the following embodiments and features can be combined with each other.

[0024] In a preferred embodiment:

[0025] This embodiment provides an adjustable angle screen wall louver, such as Figures 1-3 As shown, the angle of the louvers can be adjusted. The two ends of the plurality of louvers 5 are respectively fixedly connected to the second strip 4 by the first connector 1; each of the second strip 4 is also rotatably mounted on the first strip 2 by the first connector 1; the first strip 2 is mounted parallel to the louver frame 7; the second strip 4 is rotatably connected to the louver frame 7 by the second connector 8.

[0026] In this embodiment, the rainproof effect is enhanced by using a waterproof material on the surface of the louver 5.

[0027] In this embodiment, as Figure 4 As shown, each end of the louver 5 is provided with at least two mounting mechanisms 501; the mounting mechanism 501 can cooperate with the first connecting member and can movably connect the louver 5 to the first strip 2, so that the louver 5 can rotate relative to the first strip 2.

[0028] In this embodiment, a toggle member 6 is also included. The toggle member 6 is connected to the first strip member 2 via the first connector 1. The position of the first strip member 2 is adjusted by toggling the toggle member 6, thereby adjusting the angle of the louver 5.

[0029] In this embodiment, the cross-section of the louver 5 adopts an S-shaped structure, enabling the adjustable angle screen wall louver to simultaneously meet ventilation and rainproof requirements. When the louver 5 rotates to the position shown in the attached instruction manual... Figure 2 The optimal ventilation effect is achieved at the angle shown; when the louver 5 is rotated to the position indicated in the instruction manual... Figure 3 The optimal rainproof effect is achieved at the angle shown.

[0030] In this embodiment, as Figure 2 and Figure 3As shown, there are two first strip-shaped pieces 2, both arranged vertically; there are multiple second strip-shaped pieces 4, which are connected to the first strip-shaped pieces 2 at intervals and fixed to the louver frame 7; the actuating piece 6 is connected to one of the first connecting pieces 1. When the actuating piece 6 is actuated, it will drive the first strip-shaped pieces 2 connected to the first connecting piece 1, thereby causing all the second strip-shaped pieces 4 connected to the first strip-shaped pieces 2 to rotate; then all the louver blades 5 will rotate, achieving the angle adjustment of all the louver blades 5.

[0031] In this embodiment, both the first strip 2 and the second strip 4 are made of aluminum strips, which have the advantages of high strength and light weight, are not easy to rust or fade, are environmentally friendly and beautiful, and do not require frequent replacement.

[0032] In this embodiment, as Figure 5 As shown, the louver frame 7 adopts a segmented design, including an end frame 701 and a side frame 702. The end frame 701 is connected to the second strip 4 through a second connector 8, so that the second strip 4 can rotate around the second connector 8 as an axis, and the second strip 4 presses the first strip 2 between the end frame 701 and the second strip 4. There are two side frames 702, located on the indoor and outdoor sides of the louver 5 respectively. The end frame 701 is located at both ends of the side frames 702 and is connected to both side frames 702. This design facilitates disassembly and transportation, and also makes it easy to install the louver 5.

[0033] To illustrate the rainproof performance of this embodiment, the wall louvers were placed in a simulated environment, and water was sprayed onto them using a sprinkler device to simulate different rainfall intensities (e.g., 500-200 mm / h). A water pump and pressure gauge were used to ensure stable water flow, conforming to standards (e.g., GB / T 7106-2008 Classification of Watertightness of Building Exterior Windows). Under the simultaneous action of air supply and ventilation, the dynamic maximum rainproof performance of the wall louvers under the simultaneous action of wind and rain was tested, and the experimental results still met the standards.

[0034] How the example works:

[0035] 1. For example Figure 1 As shown, the second strip 4 is fixed to the louver frame 7 by the second connector 8 and can rotate about the axis of the second connector 8 as the center line; the louver blade 5 and the first strip 2 are both installed on the second strip 4 by the first connector 1; when the first strip 2 moves, the second strip 4 rotates about the axis of the second connector 8 as the center line, and the louver blade 5 rotates by the angle as the second strip 4 rotates.

[0036] 2. For example Figure 2 and 3As shown, since there are multiple second strips 4, and multiple second strips 4 are connected to the first strip 2 at intervals, and the actuating member 6 is connected to one of the first connecting members 1, when the actuating member 6 is actuated, it will drive the first strip 2 connected to the first connecting member 1 to move, thereby causing all the second strips 4 connected to the first strip 2 to rotate, and then causing all the louvers 5 to rotate, thus achieving the angle adjustment of all the louvers 5.

[0037] 3. When the tilt angle of louver 5 is as specified in the instruction manual... Figure 2 As shown, it meets the requirements for rain protection and has the best ventilation and lighting effects.

[0038] 4. When the louver blades are tilted at the angle specified in the instruction manual... Figure 3 As shown, it meets ventilation requirements and has the best rainproof effect.

[0039] This embodiment offers the following advantages:

[0040] (1) The angle of the curtain wall louvers can be adjusted.

[0041] (2) The mechanical structure is simple, the failure rate is low, and the service life is long.

[0042] (3) The S-shaped structure of the louvers enables them to meet the needs of ventilation and rain protection at various rotation angles.

[0043] (4) The angle of all the louvers can be adjusted by rotating the toggle.

[0044] (5) The segmented design of the louver frame facilitates the disassembly, transportation and installation of the adjustable angle screen wall louvers.
