[0057] Telescopic spring 542: Two telescopic springs 542 are provided, and both telescopic springs 542 are sleeved on the outer surface of the first sliding rod 541. One opposite end of the telescopic spring 542 is fixedly connected to the opposite side of the clamping block 520, and the opposite end of the telescopic spring 542 is fixedly connected to the inner wall of the fixed shell 530.

[0058] The above-mentioned scheme is adopted: the clamping block 520 is moved to the opposite side along the outer surface of the first sliding rod 541, and the clamping block 520 can pull the telescopic spring 542, so that the telescopic spring 542 generates tension until the spacing between the clamping blocks 520 is less than the length of the clamping groove 510. Then, the sealing strip 3 is aligned with the sealing groove 4, and the clamping block 520 can be inserted into the clamping groove 510. At this time, the telescopic spring 542 can release the tension and pull the clamping block 520 back, so that the outer surface of the clamping block 520 is in close contact with the inner wall of the clamping groove 510, thereby realizing the purpose of installing the exhaust window 2 on the surface of the wall 1.

[0077] When in use, the driving rod 572 is moved along the inner wall of the sliding groove 571, and the driving rod 572 can drive the gear 562 to rotate with the support column 563 as the rotation center. When the driving rod 572 moves to one side of the sliding groove 571, the driving rod 572 is moved inward along the limiting groove 7, so that one end of the sliding groove 571 can be pressed against the outer surface of the driving rod 572, so that the driving rod 572 is fixed, and the gear 562 rotates to engage with the tooth plate 561, so that the tooth plate 561 moves downward, and the tooth plate 561 drives the travel block 552 on the rear surface to move along the second sliding rod 6. The inner wall of the travel block 552 can squeeze the outer surface of the travel column 551, so that the travel column 551 moves along the travel block The inner wall of 552 slides, and the travel column 551 can drive the clamping block 520 to move to the opposite side along the outer surface of the first sliding rod 541. The clamping block 520 can pull the telescopic spring 542, so that the telescopic spring 542 generates tension until the spacing between the clamping blocks 520 is less than the length of the clamping groove 510. Then, the sealing strip 3 is aligned with the sealing groove 4, and the clamping block 520 can be inserted into the clamping groove 510. At this time, pull the driving rod 572 to move outward along the inner wall of the limit groove 7, and the telescopic spring 542 can release the tension, pulling the clamping block 520 back, so that the outer surface of the clamping block 520 is in close contact with the inner wall of the clamping groove 510, completing the rapid installation of the exhaust window 2.

[0078] To sum up: this kind of anti-rainwater backflow sealing device for the exhaust window, through the wall 1, the exhaust window 2, the sealing strip 3, the sealing groove 4, the fixing mechanism 5, the second sliding rod 6 and the limit groove 7, solves the problem of installing the exhaust window on the wall by bolt fixing.
