[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1-Figure 4As shown, a gas delivery pipeline connection structure includes a first connecting pipe 1, which is characterized in that: both sides of the first connecting pipe 1 are fixedly connected with movable components, the two movable components have the same structure and are symmetrical in position, the movable component includes a movable box 2, one side of the movable box 2 is fixedly connected to the first connecting pipe 1, the internal movable sleeve of the movable box 2 is movably sleeved with a sealing sleeve 7, one side of the sealing sleeve 7 is provided with a connecting groove 8, and the position of the connecting groove 8 corresponds to the first connecting pipe 1, the outside of the sealing sleeve 7 is fixedly connected to the second connecting pipe 9, the outside of the movable box 2 is provided with a limiting groove 6, the second connecting pipe 9 passes through the limiting groove 6, and the top of the second connecting pipe 9 is fixedly connected to a connecting bracket 5, a fixing hole is provided on one side of the top of the connecting bracket 5, a fixing bolt 4 passes through the fixing hole, the top of the movable box 2 is fixedly connected to the fixing bracket, and the fixing bracket A fixing groove 3 is provided above the frame, and the lower end of the fixing bolt 4 passes through the connecting fixing groove 3. Through such a setting, the fixing bolt 4 is removed and the second connecting pipe 9 is rotated. The second connecting pipe 9 moves in the limiting groove 6. The second connecting pipe 9 also drives the limiting assembly to move, and the second connecting pipe 9 drives the sealing sleeve 7 to move. Because the sealing sleeve 7 is provided with a connecting groove 8, the space inside the sealing sleeve 7 can be connected to the first connecting pipe 1 through the connecting groove 8. When the second connecting pipe 9 is rotated to the required position, the fixing bolt 4 is fixed through the fixing hole and the fixing groove 3, and the position of the second connecting pipe 9 is fixed by the connecting bracket 5. At this time, the gas transmission pipeline with a skewed angle can be connected. Through such a setting, it is convenient to connect the gas transmission pipeline with a skewed position angle, which meets the usage requirements in various situations.

[0028] like Figure 1-Figure 5 As shown, the outer sides of the two second connecting tubes 9 are fixedly connected to the limiting components, the two limiting components have the same structure and are symmetrically positioned, and the limiting components include a sealing box 10, one side of the sealing box 10 is fixedly connected to the second connecting tube 9, and the upper and lower sides of the second connecting tube 9 are fixedly connected to the installation box. Through such an arrangement, the space inside the sealing box 10 is connected to the second connecting tube 9.

[0029] like Figure 1-Figure 2 、 Figure 5-Figure 8 As shown, mounting holes are provided on the outsides of the two mounting boxes, and mounting rods are movably sleeved in the two mounting holes. Pull plates 11 are fixedly connected to the outsides of the two mounting rods, and connecting plates are fixedly connected at one end of the inner sides of the two mounting rods. First springs 12 are fixedly connected to the outsides of the two connecting plates, and the tops of the two first springs 12 are fixedly connected to the inner walls of the two mounting boxes respectively. Through such an arrangement, by pulling the pull plate 11, the pull plate 11 can drive the mounting rods to move.

[0030] like Figure 1-Figure 2 、 Figure 5-Figure 8As shown, the outer sides of the two connecting plates are fixedly connected to the limit plates 13, and the inner sides of the two limit plates 13 are abutted with a card plate 18. The gas pipe 19 is fixedly sleeved in the card plate 18, and one end of the gas pipe 19 moves in the sealing box 10. Through such a setting, the pulling plate 11 is pulled, and the pulling plate 11 drives the installation rod to move, and the installation rod drives the connecting plate to move upward. At the same time, the connecting plate drives the first spring 12 to compress, and the connecting plate drives the limit plate 13 to move upward. When the inner side of the limit plate 13 no longer abuts the card plate 18, the card plate 18 can be pulled outward, and at the same time, the card plate 18 drives the gas pipe 19 to disengage from the connection structure. The gas pipe 19 can be installed by reverse operation. Through such a setting, the disassembly and assembly of the gas transmission pipeline is convenient.

[0031] like Figure 1-Figure 2 、 Figure 5-Figure 8 As shown, one end of the inner side of the gas pipe 19 is in contact with a sealing rubber ring 16, and four connecting rods 15 are fixedly connected to the inner side of the sealing rubber ring 16 at equal intervals. Through such an arrangement, the sealing rubber ring 16 is in contact with the inner wall of the sealing box 10 at the same time, and the gas in the gas pipe 19 can be discharged from the outlet of the sealing rubber ring 16 into the sealing box 10, and then the gas enters the second connecting pipe 9 from the sealing box 10.

The outer sides of the four connecting rods 15 and the four second springs 17 are movably sleeved with the mounting block 14, and the outer side of the mounting block 14 is fixedly connected to the inner wall of the sealing box 10. Through such an arrangement, when the sealing rubber ring 16 is worn, the second spring 17 contracts to drive the connecting rod 15 to move, and the connecting rod 15 drives the sealing rubber ring 16 to move so that the sealing rubber ring 16 continues to be close to the interface of the gas pipe 19, so that the sealing rubber ring 16 continues to seal the interface of the gas pipe 19. At the same time, the mounting block 14 limits the movement of the connecting rod 15 and the sealing rubber ring 16. Through such an arrangement, it is convenient to continue to seal the gas delivery pipeline interface after the rubber ring is worn, thereby preventing gas leakage.

[0033] It should be noted that, when in use, the gas pipe 19 is connected to the external air flow. The fixing bolt 4 is removed, and the second connecting pipe 9 is rotated. The second connecting pipe 9 moves in the limiting groove 6. The second connecting pipe 9 simultaneously drives the limiting assembly to move, and the second connecting pipe 9 drives the sealing sleeve 7 to move. Because the sealing sleeve 7 is provided with a connecting groove 8, the space in the sealing sleeve 7 can be connected to the first connecting pipe 1 through the connecting groove 8.

At this time, the gas transmission pipeline with a skewed angle can be connected;

[0034] Pull the pull plate 11, the pull plate 11 drives the installation rod to move, and the installation rod drives the connecting plate to move upward. At the same time, the connecting plate drives the first spring 12 to compress, and the connecting plate drives the limit plate 13 to move upward, inserting one end of the gas pipe 19 into the sealing box 10 until the interface of the gas pipe 19 abuts against the sealing rubber ring 16. At this time, release the pull plate 11, and the first spring 12 extends through the connecting plate to drive the limit plate 13 to move. The limit plate 13 limits the card plate 18 to fix the gas pipe 19. The reverse operation can realize the disassembly of the gas pipe 19. The gas in one gas pipe 19 passes through the sealing rubber ring 16, the sealing box 10, the second connecting pipe 9, the movable box 2 and the first connecting pipe 1 and is discharged from the other gas pipe 19.

[0035] When the sealing rubber ring 16 is worn, the second spring 17 contracts and drives the connecting rod 15 to move. The connecting rod 15 drives the sealing rubber ring 16 to move so that the sealing rubber ring 16 continues to be close to the interface of the gas pipe 19, so that the sealing rubber ring 16 continues to seal the interface of the gas pipe 19. At the same time, the mounting block 14 limits the movement of the connecting rod 15 and the sealing rubber ring 16.
