Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figures 1-3 As shown, this utility model is a quick disassembly device for oxygen pipelines, comprising:

[0027] A piping assembly, comprising a first oxygen pipe 11 and a second oxygen pipe 12;

[0028] Both the first oxygen pipe 11 and the second oxygen pipe 12 are oxygen pipelines.

[0029] The disassembly assembly includes a connecting pipe 21, a fixing pipe 22, a fixing ring 23, and a insertion groove 24. The connecting pipe 21 is fixed to the opposite end of the first oxygen pipe 11, the fixing pipe 22 is fixed to the shorter end of the second oxygen pipe 12, the connecting pipe 21 and the fixing pipe 22 are threaded together, the fixing ring 23 is fixed to the opposite end surface of the second oxygen pipe 12, and the insertion groove 24 is opened on one side of the fixing ring 23 and is inserted into the connecting pipe 21.

[0030] The connecting tube 21 is used for the insertion and rotation of the fixing tube 22. The fixing tube 22 is used for the connection between the first oxygen tube 11 and the second oxygen tube 12. The fixing ring 23 is used for the opening of the insertion groove 24. The insertion groove 24 is used for the insertion of one end of the connecting tube 21.

[0031] A connecting groove 25 is provided on one side edge of the fixing ring 23. The connecting grooves 25 are set in a group, and a connecting rod 26 is inserted into the inner side of the connecting groove 25.

[0032] A ring rod 27 is fixedly connected between the outer ends of the connecting rod 26, and a sealing ring 28 is fixedly connected to the inner side of the ring rod 27.

[0033] The ring rod 27 fits into the fixed ring 23, and the sealing ring 28 is tightly attached to the connection between the connecting pipe 21 and the insertion groove 24;

[0034] The connecting groove 25 is used for the insertion of the connecting rod 26. The connecting rod 26 is used for the connection between the ring rod 27 and the fixed ring 23. The ring rod 27 is used for the connection of the sealing ring 28. The sealing ring 28 is used to seal the connection between the connecting tube 21 and the insertion groove 24. When the connecting tube 21 is inserted into the insertion groove 24, the connecting rod 26 is inserted into the connecting groove 25. The surface of the connecting rod 26 is a friction pad. The friction pad increases the friction between the connecting rod 26 and the connecting groove 25, making the two more firmly connected together. This makes the ring rod 27 and the fixed ring 23 stick together tightly. At the same time, the ring rod 27 drives the sealing ring 28 to stick tightly to the connection between the connecting tube 21 and the insertion groove 24, thereby sealing the connection between the connecting tube 21 and the insertion groove 24.

[0035] Working principle: When the component is not in use, the first oxygen tube 11 is not connected to the second oxygen tube 12. When the component is in use, hold the first oxygen tube 11 and the second oxygen tube 12 by hand, insert the fixing tube 22 into the connecting tube 21, and rotate the second oxygen tube 12 so that the second oxygen tube 12 drives the fixing tube 22 to rotate in the connecting tube 21, so that the fixing tube 22 is inserted into the thread and connected to the inside of the connecting tube 21. At the same time, one end of the connecting tube 21 is inserted into the insertion groove 24. Then, hold the ring rod 27 by hand and insert the connecting rod 26 into the connecting groove 25. The connecting rod 26 is firmly connected to the connecting groove 25 through the friction pad on the surface, so that the ring rod 27 is in close contact with one side of the fixing ring 23. At the same time, the ring rod 27 drives the sealing ring 28 to be in close contact with the connection between the connecting tube 21 and the insertion groove 24, so that the sealing ring 28 seals the connection between the connecting tube 21 and the insertion groove 24.

[0036] When disassembling the oxygen tubing, pull out the ring rod 27, causing the ring rod 27 to separate the connecting rod 26 from the connecting groove 25. Then, manually rotate the first oxygen tubing 11 and the second oxygen tubing 12, causing the connecting pipe 21 and the fixed pipe 22 to rotate in opposite directions. This allows the first oxygen tubing 11 to separate the connecting pipe 21 from the fixed pipe 22, thus achieving quick disassembly between the first oxygen tubing 11 and the second oxygen tubing 12. This facilitates maintenance personnel in handling problematic pipelines individually.

[0037] Please see Figure 1 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] Limiting components;

[0039] The limiting assembly includes a semi-ring rod 31, a mounting rod 32, and a connecting rod 33; the semi-ring rod 31 is provided in two sets, which are respectively attached to the upper and lower sides of one side of the fixing ring 23 and the upper and lower sides of one side of the ring rod 27; the mounting rod 32 is fixed between the tops of the horizontally adjacent semi-ring rods 31; and the connecting rod 33 is fixed between the outer sides of the two sides of the horizontally adjacent semi-ring rods 31.

[0040] The semi-ring rod 31 is used to connect the mounting rod 32 and the connecting rod 33. The mounting rod 32 and the connecting rod 33 are used to engage the semi-ring rod 31 between the fixed ring 23 and the ring rod 27, thereby limiting the fixed ring 23 and the ring rod 27 after insertion, and thus preventing the first oxygen tube 11 and the second oxygen tube 12 from separating.

[0041] The vertically adjacent connecting rods 33 are closely attached, and the connecting part is penetrated by a limit rod 35;

[0042] The connecting rod 33 has a limiting hole 34 at the point where it passes through the limiting rod 35, and the limiting rod 35 is threadedly connected to the limiting hole 34;

[0043] The limiting rod 35 limits the upper and lower half-ring rods 31 after they are snapped together. The limiting hole 34 is used for the rotational insertion of the limiting rod 35. The half-ring rod 31 is snapped together from the upper and lower sides of the fixed ring 23 and the ring rod 27, so that the upper and lower connecting rods 33 are in contact. The limiting rod 35 is rotated and inserted into the aligned limiting hole 34, thereby further limiting the connection between the first oxygen tube 11 and the second oxygen tube 12, preventing them from separating.

[0044] Working principle: When the component is not in use, the semi-ring rod 31 is not engaged with the fixed ring 23 and the ring rod 27. After the connecting rod 26 is inserted into the connecting groove 25, hold the semi-ring rod 31 by hand and engage it from above and below the fixed ring 23 and the ring rod 27. This makes the semi-ring rod 31 engage with the tightly fitting fixed ring 23 and the ring rod 27, so that the upper and lower connecting rods 33 fit together. This makes the limiting holes 34 on the connecting rods 33 align. Rotate the limiting rod 35 by hand and insert it into the aligned limiting hole 34, thereby limiting the engagement of the semi-ring rod 31, and further limiting the connection of the first oxygen tube 11 and the second oxygen tube 12.
