[0030] The outer wall of the sealing ring 29 contacts the inner wall of the tube body 1, the inner wall of the tube body 1 contacts the outer wall of the soft ring 26, the outer wall of the soft pad 27 contacts the inner wall of the tube body 1, the inner wall of the tube body 1 contacts the outer wall of the force ring 24, the side of the support rib 25 away from the soft ring 26 is fixedly connected to the outer wall of the force ring 24, the fixing mechanism 3 includes a fixing ring 31, and the fixing ring 31 is provided with two groups. The top of the fixing ring 31 is fixedly connected to a fixing plate 33, the outer wall of the fixing plate 33 is fixedly connected to a buckle 34, the inner wall of the fixing plate 33 is rotatably connected to a locking bolt 32, the locking bolt 32 penetrates the fixing plate 33 and is screwed into the buckle plate 35, thereby pressing the fixing plate 33 against the buckle plate 35, and the top of the fixing ring 31 is fixedly connected to the buckle plate 35.

[0031] The inner wall of the buckle plate 35 is clamped with the outer wall of the buckle 34, the outer wall of the locking bolt 32 is threadedly connected to the inner wall of the buckle plate 35, the inner wall of the fixing ring 31 is clamped with the outer wall of the tube body 1 through the limiting groove 4, and the protrusion on the fixing ring 31 is installed in the limiting groove 4, thereby limiting the position of the fixing ring 31, the inner wall of the fixing ring 31 contacts the outer wall of the limiting block 21, and the outer wall of the fixing ring 31 contacts the outer wall of the limiting angle 22.

[0032] Working principle:

[0033] When in use, first take out two leak-proof mechanisms 2, and install the two leak-proof mechanisms 2 at the two ends of the pipe body 1 respectively. It should be noted that when installing the leak-proof mechanism 2, one side of the stress ring 24 in the leak-proof mechanism 2 needs to correspond to the gas entry direction in the pipe body 1, and one side of the closed ring 29 needs to correspond to the gas outlet direction of the pipe body 1, so that in the pipe body 1, the gas first contacts one side of the stress ring 24, and then contacts one side of the closed ring 29. If the installation direction is opposite, the leak-proof function cannot be achieved. After the leak-proof mechanism 2 is installed, the fixing mechanism 3 is installed on the leak-proof mechanism 2, so as to fix the leak-proof mechanism 2 and the pipe body 1. After the fixing mechanism 3 is installed, normal gas transportation work can be started.

[0034] In installing the leak-proof mechanism 2, the connecting ring 23 is first installed on the pipe body 1 through the mounting groove 28, and two mounting grooves 28 are provided on the connecting ring 23, so the two pipe bodies 1 are installed on the mounting grooves 28 to complete the docking of the pipe bodies 1. When conveying gas, the gas first contacts the stress ring 24, so that the stress ring 24 is close to the inner wall of the pipe body 1, and at the same time, the soft ring 26 is driven to move toward the inner wall of the pipe body 1 through the supporting ribs 25, so that the soft ring 26 is close to the inner wall of the pipe body 1, thereby preventing gas leakage, and the soft pad 27 is tightly attached to the inner wall of the pipe body 1, further increasing the sealing inside the pipe body 1, and when the gas moves to the closed ring 29, the gas continuously hits the closed ring 29, so that the closed ring 29 is close to the inner wall of the pipe body 1, and the closed ring 29 is also fixed with a soft hook and a soft pad 27, thereby increasing the sealing at the closed ring 29, thereby preventing gas leakage.

[0035] After the anti-leakage mechanism 2 is installed, the anti-leakage mechanism 2 is fixed to the tube body 1 through the fixing mechanism 3. First, the two fixing rings 31 are rotated along the rotating shaft on the fixing ring 31 to expand the fixing ring 31, and the expanded fixing ring 31 is placed on the tube body 1. When installing the fixing ring 31, it is necessary to install the fixing ring 31 on the tube body 1 on both sides through the limiting groove 4. A convex block is fixed on the fixing ring 31, and it corresponds to the groove in the limiting groove 4. A groove corresponding to the limiting block 21 and the limiting angle 22 is opened on the inner wall of the fixing ring 31. Therefore, when installing the fixing ring 31, it is also necessary to align the groove with the limiting angle 22 and the limiting block 21. After the position of the fixing ring 31 is determined, the fixing ring 31 is rotated again to expand the fixing ring 3 1 is closed, and the buckle 34 on the fixing plate 33 is clamped on the pinch plate 35, so that the initial installation of the fixing ring 31 is completed. The fixing mechanism 3 after initial installation can be used in an emergency and cannot be used for a long time. After the initial installation, the locking bolt 32 passes through the fixing plate 33 and is screwed into the pinch plate 35, so that the fixing plate 33 and the pinch plate 35 are tightly attached, and the fixing ring 31 is completely installed successfully, thereby increasing the firmness of the fixing mechanism 3. After the fixing ring 31 is firmly installed, because the internal gap is closely attached, the air circulation is blocked, thereby further increasing the sealing of the tube body 1. When the fixing mechanism 3 needs to be disassembled, it is only necessary to rotate the locking bolt 32 in the opposite direction, and then separate the buckle 34 from the pinch plate 35 to remove the fixing ring 31 from the tube body 1.
