[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] The technical scheme provided by the embodiments of the present application will be described below in conjunction with the drawings.

[0028] Please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 , an embodiment of the present application provides a wind pipe flange frame, which comprises two groups of first frames 100 and two groups of second frames 200. The first frames 100 and the second frames 200 are connected in a staggered manner to form a square frame. Specifically, the outer side of the first frame 100 is integrally formed with a first blocking piece 110, and the inner side of the first frame 100 is integrally formed with a first connecting piece 120. The height of the first connecting piece 120 is higher than that of the first blocking piece 110. The first connecting piece 120 is used to be fixedly connected with a wind pipe. First mounting holes 130 are formed in the first frame 100 and the first connecting piece 120. The first connecting piece 120 can be fixedly connected with the side edge of the ventilation pipe through the first mounting holes 130 (as shown in Figure 4 ).

[0029] Please refer to Figure 1 , Figure 7 and Figure 8The outer side of the second frame 200 is integrally provided with a second blocking piece 210, and the inner side is integrally provided with a second connecting piece 220. The height of the second connecting piece 220 is higher than the height of the second blocking piece 210. The second connecting piece 220 is used to be fixedly connected with the air pipe. Second mounting holes 230 are formed in the second frame 200 and the second connecting piece 220. The second connecting piece 220 can be fixedly connected with the side of the air pipe through the second mounting holes 230 (as shown in Figure 4 ).

[0030] Please refer to Figure 3 、 Figure 5 and Figure 6 The connecting positions of the first frame 100 and the second frame 200 are provided with angle codes 300. The first frame 100 and the second frame 200 form a flange frame. The four corners of the flange frame are provided with angle codes 300 (as shown in Figure 3 ). The four corners of the flange frame are fixedly connected through the angle codes 300. Specifically, the angle code 300 includes an outer angle code 310. The two sides of the outer angle code 310 are integrally provided with inner angle codes 320. The outer side of the outer angle code 310 is aligned with the outer sides of the first frame 100 and the second frame 200. The two inner angle codes 320 are fixedly connected with the first frame 100 and the second frame 200, respectively, and are inserted into the inside of the first frame 100 and the second frame 200.

[0031] Please refer to Figure 1 、 Figure 2 and Figure 3 It should be noted that the two inner angle codes 320 are fixedly connected with the first frame 100 and the second frame 200 through rivets 400. At present, bolts are used for fixing in the market. The bolt needs to be pre-punched on the inner angle code 320. Then the bolt is inserted through the pre-existing hole of the angle code 300 and the first frame 100 or the second frame 200. Then the nut is locked. This increases the punching process. Moreover, the nut and the bolt protrude from the first frame 100 or the second frame 200 after installation, which occupies a certain space inside the flange frame, resulting in inconvenience in subsequent installation of the air pipe. The rivet riveting is used for fixing. No pre-punching is needed. After the angle code 300 and the first frame 100 and the second frame 200 are placed at the predetermined position, the riveting machine is directly riveted. The rivet penetrates the angle code 300 and the first frame 100 or the second frame 200 under the action of the riveting machine, thereby realizing the fixed connection of the two. Moreover, the rivet protrudes less and occupies less space, which is convenient for the subsequent installation and fixing of the air pipe.

[0032] Please refer to Figure 1 、 Figure 5 and Figure 6In addition, a third mounting hole 311 is formed on the outer corner code 310, and the third mounting hole 311 facilitates mounting and fixing of the whole flange frame, preferably, the reinforcing edges 321 are arranged on both sides of the inner corner code 320, and the reinforcing edges 321 abut against the inner sides of the first side frame 100 and the second side frame 200, when the corner code 300 connects the first side frame 100 and the second side frame 200, the two inner corner codes 320 are respectively inserted into the inner sides of the first side frame 100 and the second side frame 200, then the reinforcing edges 321 on both sides of the inner corner code 320 abut against the first baffle 110 and the first connecting piece 120 on both sides of the first side frame 100, and abut against the second baffle 210 and the second connecting piece 220 on both sides of the second side frame 200, so that the inner corner code 320 is more firm and stable after being inserted into the first side frame 100 and the second side frame 200, and is not easy to shake, and the strength of the whole flange frame is improved.
