[0032] In the embodiments of this utility model, please refer to Figures 1 to 6The adjusting structure 5 includes a support frame 501, which is fixedly connected to the gas tank 2. A storage frame 502 is fixedly connected to the end of the support frame 501 away from the gas tank 2. An adjusting plate 503 is slidably connected to the inner wall of the storage frame 502. A fixing plate 504 is fixedly connected to the side of the storage frame 502 away from the adjusting plate 503. A rotating shaft 505 is rotatably connected to the inner wall of the fixing plate 504. A cylinder 506 is fixedly connected to one end of the rotating shaft 505. An elastic band 507 is fixedly connected to the inner wall of the cylinder 506. A locking block 508 is fixedly connected to the end of the elastic band 507 away from the cylinder 506. A locking plate 509 is fixedly connected to the side of the adjusting plate 503 away from the storage frame 502. The arc surface of the locking block 508 is slidably connected to the locking plate 509. A positioning rod 511 is rotatably connected to one side, and a positioning plate 512 is threadedly connected to the arc surface of the positioning rod 511. A sliding rod 513 is fixedly connected to the side of the adjusting plate 503 near the positioning plate 512, and the arc surface of the sliding rod 513 is slidably connected to the positioning plate 512. An auxiliary frame 515 is fixedly connected to the side of the fixing plate 504 away from the cylinder 506, and the auxiliary frame 515 is rotatably connected to the arc surface of the rotating shaft 505. A gear 516 is fixedly connected to the arc surface of the rotating shaft 505, and a mounting block 517 is fixedly connected to the surface of the gear 516. A slide rail 518 is fixedly connected to the lower surface of the storage frame 502, and a chain 519 is slidably connected to the inner wall of the slide rail 518. One end of the chain 519 is rotatably connected to the mounting block 517, and the tooth surface of the gear 516 is in contact with the chain 519. The chain 519 is rotatably connected to a connecting block 521 at the end away from the mounting block 517. A connecting frame 522 is fixedly connected to the side of the connecting block 521 away from the chain 519. The end of the connecting frame 522 away from the connecting block 521 is fixedly connected to the adjusting plate 503. An elastic band 507 is used to bind the excess length of the outer tube to the adjusting plate 503 and the storage frame 502. The adjusting plate 503 and the elastic band 507 can extend and retract synchronously. The operation is simple and the adjustment is highly flexible. An auxiliary block 510 is fixedly connected to the side of the locking block 508 away from the adjusting plate 503. The auxiliary block 510 has arc-shaped grooves on both sides. Operating the auxiliary block 510 drives the locking block 508 to move, which is convenient for the user to move the locking block 508. The end of the locking block 508 near the locking plate 509 is round. The end of the locking block 508 near the locking plate 509 is arc-shaped, facilitating its movement into the locking plate 509. An anti-slip pad 514, made of rubber, is fixedly connected to the side of the positioning plate 512 away from the adjusting plate 503. This pad increases friction on the surface of the positioning plate 512, improving its limiting effect. Several anti-slip protrusions are fixedly connected to the end of the positioning rod 511 away from the adjusting plate 503. These protrusions are evenly distributed on the positioning rod 511, increasing friction at the operating end and facilitating rotation. A baffle 520, rectangular in shape, is fixedly connected to one side of the slide rail 518, further limiting the movement of the chain 519.To make the chain 519 move more stably, the adjusting plate 503 is a hollow plate, which reduces the weight of the adjusting plate 503 and reduces manufacturing costs.

[0033] The working principle of the inflatable device for sewage pipe repair provided by this utility model is as follows: By setting the adjustment structure 5, the locking block 508 is first moved away from the adjustment plate 503. During this process, the locking block 508 disengages from the locking plate 509. Then, the locking block 508 and the elastic band 507 are moved away from the area of ​​the adjustment plate 503 and the storage frame 502. Then, the excess length of the external pipe is wound around the adjustment plate 503 and the storage frame 502. Then, the locking block 508 is pulled closer to the locking plate 509, so that the elastic band 507 is in a stretched state, which binds the external pipe on the adjustment plate 503 and the storage frame 502. The locking block 508 is then operated. 8. Move the tray into the card plate 509. When it is necessary to adjust the overall length of the storage frame 502 and the adjusting plate 503, first rotate the positioning rod 511. The positioning rod 511 drives the positioning plate 512 to move closer to the adjusting plate 503 via the thread. At this time, the positioning plate 512 no longer presses against the inner wall of the storage frame 502, releasing the limitation on the adjusting plate 503. Then, extend the adjusting plate 503 into the storage frame 502 at a suitable distance. During this process, the adjusting plate 503 drives the connecting frame 522 closer to the storage frame 502. The connecting frame 522 then pushes the chain 519 to move through the connecting block 521. The chain 519 moves along the slider closer to the auxiliary frame 515. As the direction moves, the chain 519 drives the gear 516 and the shaft 505 to rotate via the mounting block 517. During the rotation of the gear 516, it meshes with the chain 519. Meanwhile, the shaft 505 drives the cylinder 506 to rotate along the fixed plate 504. The cylinder 506 winds up the elastic band 507. When the overall length of the adjusting plate 503 and the storage frame 502 decreases, the length of the elastic band 507 also decreases simultaneously. Then, the positioning rod 511 rotates in the opposite direction. The positioning rod 511, through its threads, drives the positioning plate 512 away from the adjusting plate 503. The positioning plate 512 presses against the inner wall of the storage frame 502, fixing the position of the adjusting plate 503. The operation auxiliary block 510 drives the locking block 508 to move, making it easier for the user to move the locking block 508. The end of the locking block 508 near the locking plate 509 is arc-shaped, making it easier for the locking block 508 to move into the locking plate 509. The anti-slip pad 514 increases the friction on the surface of the positioning plate 512, making the positioning plate 512 more effective in limiting the position. The anti-slip protrusion increases the friction at the operating end of the positioning rod 511, making it easier for the user to rotate the positioning rod 511. The baffle 520 further limits the chain 519, making the chain 519 more stable when moving. The adjusting plate 503 is a hollow plate, which reduces the weight of the adjusting plate 503 and reduces manufacturing costs.
