Detailed Implementation

[0019] 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.

[0020] See Figures 1 to 7 This embodiment discloses a flow guiding device for a fire damper, including a housing 100. Two rotatable flow guiding plates 200 are disposed within the housing 100. Each flow guiding plate 200 includes a rotating shaft 210 and a first plate 220 and a second plate 230 positioned on either side of the rotating shaft 210. The first plate 220 is connected to a sealing plate 300 that abuts against the second plate 230 of the adjacent flow guiding plate 200. A drive motor 110 is mounted on the outer wall of the housing 100. The drive motor 110 is connected to the rotating shaft 210 of one of the two flow guiding plates 200, thereby driving the connected flow guiding plate 200 to rotate. A support rod 410 is connected to the second plate 230. The support rods 410 of the two second plates 230 are connected by a connecting rod 400, so that the rotation of one flow guiding plate 200 can drive the rotation of the other flow guiding plate 200.

[0021] The first plate 220 has a first extension 221 at one end, and a second extension 222 perpendicular to it. The second extension 222 is parallel to the first plate 220, so that the first plate 220, the first extension 221, and the second extension 222 form a first connecting groove 223. The second plate 230 has a third extension 231 at one end, and the third extension 231 is parallel to the first extension 221.

[0022] A first support plate 310 is provided at one end of the sealing plate 300 facing the first plate 220. A fifth extension 312 is provided on one side of the first support plate 310. The first support plate 310 is perpendicular to the sealing plate 300, and the fifth extension 312 is parallel to the sealing plate 300, so that the sealing plate 300, the first support plate 310, and the fifth extension 312 form a second connecting groove 313. When the fifth extension 312 is inserted into the first connecting groove 223, the second extension 222 is also inserted into the second connecting groove 313, thereby fixing the first plate 220 and the sealing plate 300.

[0023] A fourth extension 311 is provided on the side of the first support plate 310 opposite to the side where the fifth extension 312 is located. The first plate 220 is provided with an abutment 500 to restrict the movement of the sealing plate 300. Specifically, the first plate 220 is provided with a first opening 224. The abutment 500 includes a connecting part 520 and an abutment part 530 that are perpendicular to each other. The abutment part 530 abuts against the fourth extension 311. The connecting part 520 is inserted into the first opening 224 and extends through the first opening 224 to the other side of the first plate 220. The part of the connecting part 520 that extends through the first opening 224 has a second opening 510. A limiting plate 600 passes through the second opening 510. The limiting plate 600 abuts against the other side of the first plate 220, thereby restricting the movement of the sealing plate 300 and ensuring the stability of the connection between the first plate 220 and the sealing plate 300. During disassembly, simply pull out the limiting plate 600 from the second opening 510 and then pull out the abutment 500 from the first opening 224 to pull out the fifth extension 312 from the first connecting groove 223, which facilitates the disassembly and assembly of the sealing plate 300.

[0024] A second support plate 320 is provided at one end of the sealing plate 300 facing the second plate 230. A third support plate 330 is provided between the first support plate 310 and the second support plate 320. The second support plate 320 and the third support plate 330 form a third connecting groove 340. A sealing element 700 is embedded in the third connecting groove 340. The sealing element 700 includes a support part 710 and a deformation part 720. The support part 710 is embedded in the third connecting groove 340. The length of the third support plate 330 is less than the length of the second support plate 320. The deformation part 720 extends toward the side where the third support plate 330 is located.

[0025] When the second plate 230 abuts against the sealing plate 300, the second plate 230 contacts the second support plate 320, and the third extension 231 is placed between the first support plate 310 and the third support plate 330 and contacts the sealing plate 300. At this time, the second plate 230 covers the third connecting groove 340, and the third extension 231 covers the third support plate 330, thereby squeezing the sealing member 700 from two directions, causing the deformable part 720 to deform and fill the space enclosed by the sealing plate 300, the third support plate 330, the second plate 230, and the third extension 231, ensuring the sealing performance between the second plate 230 and the sealing plate 300.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
