[0028] The following further elaborates on this application through the drawings and embodiments.

[0029] Refer to Figures 1 to 4, an embodiment of the present application provides a gas hose fixing ring, which includes an intake pipe 1 and a connecting pipe 4. A first outer block 5 is fixedly installed on the right side of the intake pipe 1, and a second outer block 6 is fixedly installed on the left side of the connecting pipe 4. A connecting component 2 is arranged between the first outer block 5 and the second outer block 6, and an auxiliary component 3 is arranged inside the first outer block 5 and the second outer block 6. The connecting component 2 includes an internal thread cylinder 24 and an external thread cylinder 25. The internal thread cylinder 24 is rotatably connected to the right side of the first outer block 5, the external thread cylinder 25 is fixedly installed on the left side of the second outer block 6, and the internal thread cylinder 24 is screwed on the outside of the external thread cylinder 25. A second baffle 34 is fixedly installed inside the first outer block 5, a sealing cylinder 35 is fixedly installed on the left side of the second baffle 34, a spring 37 is fixedly installed on the left side of the second baffle 34 and outside the sealing cylinder 35, and a sealing cover 36 is fixedly installed on the left side of the spring 37. The sealing cover 36 fits on the left side of the sealing cylinder 35.

[0030] A sealing gasket is fixedly installed at the connection between the sealing cover 36 and the sealing cylinder 35 and on the left side of the sealing cylinder 35. Both the sealing cylinder 35 and the sealing cover 36 are located inside the first outer block 5. A first baffle 33 is fixedly installed inside the external thread cylinder 25, a plug cylinder 31 is fixedly installed on the left side of the first baffle 33, and a communication groove 32 is formed on the outer side wall of the plug cylinder 31. The plug cylinder 31 is inserted into the sealing cylinder 35.

[0031] In this embodiment, when installing the gas hose 7, the connecting pipe 4 is installed on the gas-using equipment. During installation, by rotating the internal thread cylinder 24, the internal thread cylinder 24 is screwed on the outside of the external thread cylinder 25, so that the intake pipe 1 and the connecting pipe 4 can be connected to realize the gas supply. During installation, the plug cylinder 31 is inserted into the sealing cylinder 35. After insertion, the plug cylinder 31 pushes open the sealing cover 36, and the spring 37 is stretched after being pushed open. The intake pipe 1 and the connecting pipe 4 are communicated through the communication groove 32 on the outside of the plug cylinder 31 to ensure the normal flow of gas. When the connected intake pipe 1 and connecting pipe 4 are accidentally disconnected, the plug cylinder 31 no longer presses the sealing cover 36. Under the contraction force of the spring 37, the sealing cover 36 covers the outside of the sealing cylinder 35 again, thereby sealing the intake pipe 1, and thus achieving the purpose that gas cannot be discharged after fracture.

[0032] Refer to Figures 1 to 4 , in one aspect of this embodiment, the left side of the external thread cylinder 25 fits on the right side wall of the first outer block 5, and a sealing gasket is fixedly installed at the connection between the external thread cylinder 25 and the first outer block 5 and on the right side of the first outer block 5.

[0033] On the upper and lower sides of the first outer block 5 and the upper and lower sides of the second outer block 6, screw rods 22 are fixedly installed. A connecting plate 21 is sleeved on the outer sides between the left and right corresponding screw rods 22. A nut 23 is screwed on the outer side of the screw rod 22, and the nut 23 is located above the connecting plate 21. A hose 7 is fixedly installed on the left side of the air inlet pipe 1, and the hose 7 is communicated with the inside of the air inlet pipe 1.

[0034] In this embodiment, when connecting the air inlet pipe 1 and the connecting pipe 4, the connecting plate 21 can be sleeved between the two screw rods 22. After sleeving, the nut 23 is screwed on the outer side of the screw rod 22, so that the connecting plate 21 can be fixed between the first outer block 5 and the second outer block 6. By assisting in fixing the first outer block 5 and the second outer block 6, the connection stability between the air inlet pipe 1 and the connecting pipe 4 can be greatly improved, and the probability of fracture can be greatly reduced.

[0035] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0036] Working principle: When installing the gas hose 7, the connecting pipe 4 is installed on the gas-using equipment. During installation, the internal thread cylinder 24 is screwed on the outer side of the external thread cylinder 25 by rotating the internal thread cylinder 24, so that the air inlet pipe 1 and the connecting pipe 4 can be connected to realize the gas supply. During installation, the insertion cylinder 31 is inserted into the sealing cylinder 35. After insertion, the insertion cylinder 31 pushes open the sealing cover 36, and the spring 37 is stretched after being pushed open. The air inlet pipe 1 and the connecting pipe 4 are communicated through the communication groove 32 on the outer side of the insertion cylinder 31 to ensure the normal flow of gas. When the connected air inlet pipe 1 and the connecting pipe 4 are accidentally disconnected, the insertion cylinder 31 no longer presses the sealing cover 36. Under the contraction force of the spring 37, the sealing cover 36 is re-covered on the outer side of the sealing cylinder 35, thereby sealing the air inlet pipe 1, so as to achieve the purpose that gas cannot be discharged after fracture; when connecting the air inlet pipe 1 and the connecting pipe 4, the connecting plate 21 can be sleeved between the two screw rods 22. After sleeving, the nut 23 is screwed on the outer side of the screw rod 22, so that the connecting plate 21 can be fixed between the first outer block 5 and the second outer block 6. By assisting in fixing the first outer block 5 and the second outer block 6, the connection stability between the air inlet pipe 1 and the connecting pipe 4 can be greatly improved, and the probability of fracture can be greatly reduced.
