Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Referring to Figures 1 to 5 , a louver includes a window opening, the window opening includes a first horizontal frame 110 and a second horizontal frame 120 extending in the horizontal direction. The first horizontal frame 110 and the second horizontal frame are arranged vertically up and down, and the first horizontal frame 110 is located above the second horizontal frame 120. A first vertical frame 130 and a second vertical frame 140 extending in the vertical direction are arranged between the first horizontal frame 110 and the second horizontal frame 120. An installation cavity 150 is provided in the first vertical frame 130 and the second vertical frame 140. A support shaft 151 is provided in the installation cavity 150. The support shaft 151 is rotatably connected to a connecting rod 300. One end of the connecting rod 300 is provided with a blade 200, and the other end is provided with a driving rod 400. The driving rod 400 is connected to a power source 500, and the power source 500 is a motor or a cylinder. By driving the driving rod 400 to move through the power source 500 and driving the blade 200 to rotate through the connecting rod 300, the opening and closing of the louver can be realized. A plurality of blades 200 are provided, and each blade 200 is installed on two corresponding connecting rods 300, so that the driving rod 400 can drive a plurality of blades 200 to rotate synchronously.

[0021] The blade 200 includes an upper edge 201 and a lower edge 202. When the blade 200 is closed, the upper edge 201 faces the first horizontal frame, and the lower edge 202 faces the second horizontal frame. The upper edge 201 is connected with a first extension plate 210, and the included angle between the first extension plate 210 and the blade 200 is an obtuse angle. The lower edge 202 is connected with a second extension plate 220, and the included angle between the second extension plate 220 and the blade 200 is an obtuse angle. The surface of the blade 200 facing the driving rod 400 is the inner surface 203, and the opposite surface is the outer surface 204. The end of the first extension plate 210 is provided with a first seal protruding toward the side where the inner surface 203 is located, and the end of the second extension part 212 is provided with a second seal protruding toward the side where the outer surface 204 is located. When the blade 200 is closed, the first seal can be engaged with the second seal of the adjacent blade 200, thereby improving the sealing performance between the blades 200 and preventing rainwater from seeping into the room.

[0022] The first seal includes a first extension portion 211 and a second extension portion 212, and the second seal includes a third extension portion 221. When the blade 200 is closed, the first extension portion 211 abuts against the second extension plate 220 of the adjacent blade 200, and the third extension portion 221 abuts against the first extension plate 210 of the adjacent blade 200. When abutting, slight deformation will occur between the first extension portion 211 and the third extension portion 221, causing the first extension portion 211 to squeeze the second extension plate 220 and the third extension portion 221 to squeeze the first extension plate 210, thereby increasing the sealing performance between adjacent blades 200. A limiting groove 222 is provided on the third extension portion 221. When the blade 200 is closed, the end of the second extension portion 212 is embedded in the limiting groove 222 and squeezes the third extension portion 221, thereby further increasing the pressure of the third extension portion 221 on the corresponding first extension plate 210 and further improving the sealing performance between adjacent blades 200.

[0023] Connection grooves 230 are provided on the end faces where the first extension plate 210 is connected to the blade 200 and the end faces where the second extension plate 220 is connected to the blade 200, and plug connectors 240 are provided on the upper edge 201 and the lower edge 202 of the blade 200. Limiting openings 231 are provided on the side walls of the connection grooves 230, and protrusions 241 are provided on the plug connectors 240. When the plug connectors 240 are inserted into the connection grooves 230, the protrusions 241 are embedded in the limiting grooves 222, so that the first extension plate 210 or the second extension plate 220 is fixed to the blade 200 to facilitate the installation and disassembly of the first extension plate 210. When the sealing performance of the first extension plate 210 or the second extension plate 220 is insufficient due to wear, aging, etc., it is convenient to replace.

[0024] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
