[0025] In order to achieve the purpose of connecting the first gas pipeline 1 with the second gas pipeline 31, refer to Figure 2 The connecting mechanism 2 includes a sealing tube 21, and the left end of the outer surface of the sealing tube 21 is fixedly connected to an external threaded tube 22, which can drive the sealing tube 21 into the inner cavity of the installation groove 32 so that the inner cavities of the first gas pipe 1 and the second gas pipe 31 are completely sealed, and the right end of the outer surface of the sealing tube 21 is fixedly connected to the left end of the outer surface of the first gas pipe 1.

[0026] In order to achieve the purpose of connecting with the external threaded pipe 22, refer to Figure 2 The matching component 3 includes a second air delivery pipe 31, and a mounting groove 32 communicating with the outside is opened at the right part of the inner cavity of the second air delivery pipe 31. An internal threaded rubber ring 33 is fixedly connected to the left part of the inner cavity of the mounting groove 32, and the inner surface of the internal threaded rubber ring 33 is threadedly connected to the outer surface of the external threaded pipe 22.

[0027] When it is necessary to connect the first air pipe 1 with the second air pipe 31, the first air pipe 1 is rotated to drive the external threaded pipe 22 to be threadedly connected with the inner cavity of the internal threaded rubber ring 33, so that the external threaded pipe 22 is rotated into the inner cavity of the internal threaded rubber ring 33, and the inner cavity of the internal threaded rubber ring 33 is squeezed so that its inner surface is completely in contact with the outer surface of the external threaded pipe 22.

[0028] In order to monitor whether there is gas leakage at the connection between the first gas pipeline 1 and the second gas pipeline 31, refer to Figure 3The monitoring mechanism 4 includes an annular casing 41, and a plurality of air holes 42 communicating with the outside are opened in an annular array on the inner surface of the annular casing 41.

[0029] When there is a gas leak between the first gas pipe 1 and the second gas pipe 31, the leaked gas will enter the inner cavity of the annular casing 41 through the plurality of air holes 42, and then the gas alarms 43 will sound an alarm after being sensed to remind people around that there is a danger of gas leakage.

[0030] In order to achieve the purpose of carrying the buffer mechanism 6 and the protection mechanism 7, refer to Figure 4 The bearing mechanism 5 includes a supporting frame 51, and a plurality of U-shaped connecting plates 52 are fixedly connected in an annular array on the outer surface of the supporting frame 51, so as to support and fix the two corresponding buffer mechanisms 6.
