[0026] The connecting assembly includes a circular flange 3 and a circular flat iron 4, the circular flat iron 4 is installed on the inner wall of the circular flange 3, the circular flange 3 is arranged on the glass fiber reinforced plastic air duct 1, and the outer wall of the circular flat iron 4 is adapted to the inner wall of the glass fiber reinforced plastic air duct 1;

[0027] The circular flat iron 4 is provided with a plurality of through holes 1, and the FRP air duct 1 is provided with a plurality of through holes 2, which are matched with each other. The FRP air duct 1 and the circular flat iron 4 are sealed and connected by a plurality of fixing bolts 5, and both the through holes 1 and the through holes 2 are matched with the fixing bolts 5.

[0028] The outer diameter of the annular flange 3 is 10 cm larger than the outer diameter of the glass fiber reinforced plastic air duct 1.

[0029] The annular flange 3 is provided with a plurality of through holes 3 , and the two annular flanges 3 are connected via a plurality of fixing components 6 .

[0030] The fixing assembly 6 is composed of a fixing insert 61 , a plurality of limit blocks 62 , a fixing ring 63 , a limit insert plate 64 and an elastic column 65 . The fixing insert 61 passes through the through hole three on the two annular flanges 3 and is slidably connected with the through hole three.

[0031] The fixed insert 61 is provided with a plurality of through openings, and the plurality of limit blocks 62 are connected to the fixed insert 61 through torsion springs, and the plurality of limit blocks 62 are adapted to the through openings.

[0032] The fixing ring 63 is connected to one end of the fixing insert 61 away from the limiting block 62, the limiting plug plate 64 is slidably installed on the fixing ring 63, the elastic column 65 is slidably installed in the fixing insert 61, and the two ends of the elastic column 65 are respectively adapted to multiple limiting blocks 62 and limiting plug plates 64.

[0033] The outer walls of the two annular flanges 3 on one side close to each other are both provided with sealing rings, so that the sealing performance between the two can be improved by the sealing rings (the sealing rings are existing finished products and therefore not shown in the figure).

[0034] The working principle of the installation structure for connecting the glass fiber reinforced plastic air duct and the flange provided by the utility model is as follows:

[0035] The first step: when in use, the circular flat iron 4 is inserted into the FRP air duct 1, and the circular flange 3 is in contact with the FRP air duct 1, and then the FRP air duct 1 is rotated by the circular flange 3, so that the through hole 2 on the circular flat iron 4 and the through hole 1 on the FRP air duct 1 are aligned one by one (before alignment, glue is first applied on the outer wall of the circular flange 3 on the side close to the FRP air duct 1), and then a plurality of fixing bolts 5 are inserted into the corresponding through hole 1 and through hole 2, so that the FRP air duct 1 and the circular flat iron 4 can be sealed and connected (the through hole is sealed with structural glue on site after fixing), and the other connecting component is connected to the FRP air duct 2 in the same way;

[0036] Step 2: After the FRP air duct 1, FRP air duct 2 and two connection components are connected, the fixed insert 61 is passed through the through hole 3 on the two annular flanges 3, and the fixed ring 63 is in contact with the annular flanges 3, and then one end of the elastic column 65 is inserted into the fixed insert 61 through the fixed ring 63 and the plurality of limit blocks 62 are squeezed, so that the limit blocks 62 are exposed through the through opening and contact the annular flanges 3 to form a block, and finally the limit plug 64 is inserted into the fixed ring 63 to form a clamping connection;

[0037] The third step: pull out the limit plate 64, extract the elastic column 65, and in the absence of the squeezing effect of the elastic column 65, receive the limit block 62 through the opening, and then pull out the fixing sleeve 61, so as to cancel the fixation of the two annular flanges 3, so that they can be easily separated and disassembled.
