[0026] As Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes an outer housing 1. Inside the cavity of the outer housing 1, several support rods 3 are distributed. The side walls of the several support rods 3 are jointly connected to an inner housing 4. An end of the outer ring of the outer housing 1 is sleeved with a connecting ring 5. A first sealing groove 6 is opened on one side of the connecting ring 5. A first sealing ring 7 is movably arranged in the cavity of the first sealing groove 6. Connecting holes 8 are respectively and penetratingly opened in the first sealing ring 7 and the cavity of the connecting ring 5. A screw rod 9 is movably arranged in the cavity of the connecting hole 8. A nut 10 is threadedly connected to the outer ring of the screw rod 9.

[0027] Among them, an inner support ring 11 is sleeved at the end of the cavity of the inner housing 4. A second sealing groove 12 is opened on the side wall of the inner support ring 11. A second sealing ring 13 is movably arranged in the cavity of the second sealing groove 12.

[0028] Among them, both the first sealing ring 7 and the second sealing ring 13 are made of silica gel.

[0029] In this embodiment, as Figure 2 shown, when the connection of two pipes is completed, at this time, the first sealing ring 7 is located in the two first sealing grooves 6 and is limited by the connecting ring 5, and the second sealing ring 13 is located in the two second sealing grooves 12 and is limited by the inner support ring 11. Thus, double sealing is performed on the inner and outer sides of the pipe connection, which can greatly improve the sealing performance of the pipe, prevent the gas in the pipe from leaking out from the connection, and prevent the external air flow from entering the pipe from the connection. The overall practicality is relatively strong. At the same time, the inner support ring 11 and the connecting ring 5 can strengthen the ends of the outer housing 1 and the inner housing 4, avoiding the situation that when the pipe is transported or collided, its port is sunken and deformed, resulting in the influence on the sealing effect, and improving the durability of the pipe.

[0030] Among them, rock wool is filled between the two support rods 3, and a fireproof coating is applied on the surface of the outer housing 1.

[0031] In this embodiment, the support rods 3 can improve the overall strength of the pipe, avoiding the situation that the pipe is sunken after being impacted, resulting in the pulling of the connection and further affecting the sealing performance of the pipe. The rock wool and the fireproof coating can improve the fire resistance of the pipe, to a certain extent avoiding the situation that the pipe is burned or melted, and improving the use reliability of the pipe.

[0032] Among them, as Figure 3 shown, a sealing sleeve 14 is sleeved in the cavity of the inner housing 4, and a hot melt adhesive is applied on the outer surface of the sealing sleeve 14.

[0033] In this embodiment, the sealing sleeve 14 can prevent the gas leakage caused by the aging or damage of the first sealing ring 7 or the second sealing ring 13, further strengthening the sealing performance of the pipe. And by applying the hot melt adhesive on the surface of the sealing sleeve 14, it is convenient to install the sealing sleeve 14, improving the use convenience of the structure.

[0034] Among them, as Figure 2 shown, a number of anti-slip lines 15 are provided on the outer wall of the sealing sleeve 14.

[0035] In this embodiment, the anti-slip lines 15 can enhance the grip of the hot melt adhesive on the sealing sleeve 14, thereby improving the connection strength between the sealing sleeve 14 and the inner housing 1, making it difficult for the sealing sleeve 14 to fall off or displace, and improving the use stability of the device.
