[0018] A preferred specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0019] See also Figures 1 to 3 This embodiment provides a shutter frame, which is formed by bending a plate 100 to form a base 1, and two opposite sides of the base 1 ( Figure 3 The first side circumference 2 is arranged on the front and rear sides of the base 1, and the second side circumference 2 is arranged on the second opposite sides of the base 1 ( Figure 3 The plate 100 is horizontally bent along the edge of the base 1 at the first two opposite sides to form a first flat folded portion 21, and is vertically bent along the first flat folded portion 21 to form the above-mentioned first side enclosure 2. The plate 100 is horizontally bent along the edge of the base 1 at the second two opposite sides to form a second flat folded portion 31, and is vertically bent along the second flat folded portion 31 to form the above-mentioned second side enclosure 3, as shown in the left and right sides. Figure 1 and Figure 3 As shown, the first flat folded portion 21 and the second flat folded portion 31 are horizontally abutted against the upper end surface of the base 1 after being bent, and the first side surround 2 and the second side surround 3 are bent outward once respectively to form a vertical state. The adjacent first side surrounds 2 and the second side surrounds 3 are combined with each other to form a cavity 200 surrounded by the first side surrounds 2, the second side surrounds 3 and the base 1, and the cavity 200 is used to install and support the blades of the shutter. An air flow hole 12 is opened in the middle of the base 1, and the shutter frame is used to connect the fan. When installing, the fan is installed on the back of the base 1, and gas exchange with the outside is achieved through the air flow hole 12 during operation.

[0020] The first flat folding portion 21 includes the following two configurations:

[0021] See also Figure 1 and Figure 3 As a first arrangement form, the two opposite sides of the first flat folded portion 21 extend reinforcing convex portions 23 covering the upper end surface of the corner of the base 1, and the reinforcing convex portions 23 are adapted to the contour of the corner of the base 1. The extended reinforcing convex portions 23 form a wrap angle covering the upper end of the corner of the base 1, thereby protecting the base 1 and making the frame surface more complete and beautiful. The double-layer structure formed by the reinforcing convex portions 23 and the base 1 can improve the strength of the frame corner. In order to further improve the strength, the reinforcing convex portions 23 are fixedly connected to the adjacent second flat folded portion 31, for example, by welding.

[0022] See also Figure 1 and Figure 4 As a second configuration, a notch 11 is formed between the first flat folded portion 21 and the second flat folded portion 31 to expose the upper end surface of the corner of the base 1. The above configuration does not include corner wrapping. Compared with the first configuration, the notch 11 can simplify the structure, save materials, and reduce the weight of the frame to a certain extent.

[0023] See also Figures 1 to 3On one side, first inner folding portions 24 extend from opposite sides of the first side enclosure 2, and on the other side, first outer folding portions 25 extend from opposite sides of the first side enclosure 2. The first inner folding portions 24 are bent to abut against the inner side surface of the second side enclosure 3, and the first outer folding portions 25 are bent to abut against the outer side surface of the second side enclosure 3. The first inner folding portions 24 are connected to the second side enclosure 3, and the first outer folding portions 25 are connected to the second side enclosure 3. The first inner folding portions 24 and the second side enclosure 3 are connected by screws or rivets, and / or the first outer folding portions 25 and the second side enclosure 3 are connected by screws or rivets.

[0024] See also Figures 1 to 3 , the first side enclosure 2 provided with the first inner folding portion 24 has an integrally formed second inner folding portion 26 at its upper end, the second inner folding portion 26 is bent between the second side enclosures 3 on both sides and abuts against the upper end of the first inner folding portion 24. The first side enclosure 2 provided with the first outer folding portion 25 has an integrally formed second outer folding portion 27 at its upper end, the second outer folding portion 27 is bent to abut against the upper ends of the second side enclosures 3 on both sides, and the bent second outer folding portion 27 is higher than the second inner folding portion 26. Since the shutter frame is used to mount blades, the blades are provided in multiple pieces, and are stacked from the end of the frame provided with the second outer folding portion 27 to the end provided with the second inner folding portion 26 from top to bottom, so the second inner folding portion 26 is provided for the blades of the bottom layer to be laid on the upper end thereof, and the second outer folding portion 27 is provided for shielding the gap formed between the blades of the top layer and the second side enclosure 3, thereby blocking rainwater and foreign matter.

[0025] See also Figures 1 to 3 The upper ends of the second side enclosures 3 on both sides are bent inward to form flanges 33 located above the second inner folded portion 26 . The provision of the flanges 33 can improve the strength of the outer edge of the second side enclosure 3 .

[0026] The utility model forms a base 1 and a side enclosure that enclose a cavity 200 by bending a plate 100 multiple times, and has the following technical effects compared with the prior art:

[0027] Enhanced Structural Strength:

[0028] Through the continuous and integrated outer contour design, the double-layer structure formed by the base 1 and the first flat folding portion 21 and the second flat folding portion 31 can significantly enhance the compression resistance and impact resistance of the frame. This design enables the frame to better disperse and resist these forces when subjected to external pressure or impact, thereby ensuring the stability and durability of the frame.

[0029] Excellent sealing performance:

[0030] The connection gap between the base 1 and the side wall is eliminated, effectively preventing foreign objects such as dust and sand from entering through the gap. This not only improves the cleanliness of the frame, but also reduces the maintenance frequency. More importantly, this design enables the frame to provide better protection under adverse weather conditions such as strong winds, heavy rain, and blizzards, ensuring the safety and dryness of the internal space.

[0031] Improved aesthetics and integrity:

[0032] The integrated frame design makes the entire structure look simpler. At the same time, the lack of obvious connection gaps also improves the integrity and texture of the frame.

[0033] Convenient assembly and disassembly:

[0034] Although this technology forms a complex structure by bending a plate multiple times, its assembly and disassembly process may actually be simpler and faster because all parts are integrated and do not require complicated connectors or tools. Assembly or disassembly can be completed with simple operations.

[0035] Environmental protection and sustainability:

[0036] By reducing the use of connectors and complex processes, this design reduces material and energy consumption, which is in line with the concepts of environmental protection and sustainable development. At the same time, due to its excellent durability and reusability, it also reduces waste generation and environmental pollution.
