[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a special oxygen inhalation tube for the Qinghai-Tibet Railway provided by this utility model; Figure 2 for Figure 1 The diagram shown is a structural schematic of an oxygen inhalation tube. Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 1 The image shows a side view of an oxygen inhalation tube. A special oxygen inhalation tube for the Qinghai-Tibet Railway includes:

[0028] The system includes an oxygen inhalation main tube 5, a connector 6, a three-way connector 4, two branch tubes 2, a nasal four-way connector 1, and a tightening sleeve 3. The connector 6 is connected to one end of the oxygen inhalation main tube 5, the three-way connector 4 is connected to one end of the oxygen inhalation main tube 5, the two branch tubes 2 are both connected to one end of the three-way connector 4, and the nasal four-way connector 1 is located between the two main tubes 2.

[0029] The fastening sleeve 3 is fitted onto the surface of the branch pipe 2.

[0030] The tightening sleeve 3 is used to adjust the tightness of the branch pipe 5.

[0031] The tee connector 4 is used to deliver oxygen into the two branch pipes 2.

[0032] Connector 6: Used to connect directly to the oxygen interface on the train, it is the connection port for obtaining oxygen through the oxygen inhalation tube.

[0033] Oxygen supply main pipe 5: One end is connected to connector 6, which is responsible for transmitting oxygen introduced from the train interface and is the main channel for oxygen delivery.

[0034] T-connector 4: Connected to the other end of the oxygen main pipe 5, it diverts the oxygen from the oxygen main pipe to the two branch pipes 2.

[0035] Branch tube 2: There are two in total, each connected to one end of the three-way connector 4, which will deliver the oxygen diverted from the three-way connector to the nasal cavity, providing the user with an oxygen inhalation path.

[0036] Nasal Itch Four-way Connector 1: Located between the two branch tubes 2, it is the terminal component for oxygen to enter the human nasal cavity. Its smooth curved surface design can prevent irritation of the nasal mucosa.

[0037] Tightening sleeve 3: Sleeves over the surface of branch tube 2, allowing for adjustment of the branch tube's tightness to suit different users' needs and improve the comfort and stability of the oxygen tubing.

[0038] The working principle of the special oxygen inhalation tube for the Qinghai-Tibet Railway provided by this utility model is as follows:

[0039] In use, first insert connector 6 directly into the oxygen interface on the train to connect the oxygen source. The oxygen is transmitted through the main oxygen inhalation tube 5. When the oxygen reaches the three-way connector 4, it is split into the left and right branch tubes 2, which correspond to the two nasal cavities respectively. The tightening sleeve 3 can adjust the length of the branch tubes according to the user's actual situation to ensure that the oxygen inhalation tube is worn properly. Finally, the oxygen enters the human nasal cavity smoothly through the four-way nasal connector 1 to provide oxygen to the user and meet the oxygen inhalation needs of passengers in the low-oxygen environment along the Qinghai-Tibet Railway. At the same time, the oxygen inhalation tube is designed with train usage scenarios in mind, and has anti-drop and anti-drag functions to ensure stable operation even when the train is bumpy.

[0041] This utility model provides a special oxygen tube for the Qinghai-Tibet Railway. It features a connector 6, a three-way connector 4, two branch pipes 2, a nasal four-way connector 1, and a tightening sleeve 3 at both ends of the main oxygen tube 5. These components work together to withstand the extreme low temperatures and low air pressure along the Qinghai-Tibet Railway, ensuring normal operation under harsh conditions. It meets the requirements for rapid replacement and cleaning in train use scenarios, facilitating equipment maintenance and hygiene. The special structural design effectively prevents the oxygen tube from falling off or being dragged during train bumps, enhancing stability during use and providing passengers with a safe and stable oxygen experience.

[0042] Second Embodiment

[0043] Please refer to the following: Figure 5 and Figure 6 Based on the first embodiment of this application which provides a special oxygen inhalation tube for the Qinghai-Tibet Railway, the second embodiment of this application proposes another special oxygen inhalation tube for the Qinghai-Tibet Railway. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0044] Specifically, the second embodiment of this application provides a special oxygen inhalation tube for the Qinghai-Tibet Railway, which differs in that a disassembly assembly 7 is provided between the branch pipe 2 and the nasal four-way connector 1. The disassembly assembly 7 includes a connecting disassembly sleeve 71, a connecting disassembly head 72, a rubber pad 73, and a delivery pipe 74. The connecting disassembly sleeve 71 is connected to one end of the branch pipe 2, and the connecting disassembly head 72 is threadedly connected to one end of the connecting disassembly sleeve 71.

[0045] The rubber pad 73 is disposed between the connecting disassembly sleeve 71 and the connecting disassembly head 72.

[0046] The delivery pipe 74 is connected to one end of the connecting disassembly head 72.

[0047] The connecting disassembly sleeve 71 and the connecting disassembly head 72 are used for disassembling and replacing the nasal four-way connector 1.

[0048] Connecting disassembly sleeve 71: Connected to one end of branch pipe 2, serving as a connecting component between the disassembly assembly and the branch pipe.

[0049] Connecting disassembly head 72: Connected to connecting disassembly sleeve 71 by threads, facilitating disassembly and installation.

[0050] Rubber gasket 73: Located between the connecting disassembly sleeve 71 and the connecting disassembly head 72, it serves as a seal to prevent oxygen leakage.

[0051] Delivery tube 74: One end is connected to the connecting and disconnecting head 72, and the other end is connected to the nasal four-way connector 1. It is the channel for oxygen to be transmitted from the branch tube to the nasal four-way connector.

[0052] The working principle of the special oxygen inhalation tube for the Qinghai-Tibet Railway provided by this utility model is as follows:

[0053] Oxygen flows from the main oxygen supply tube to branch tube 2 via the three-way connector. It then passes through the connecting disassembly sleeve 71. Due to the sealing effect of the rubber gasket 73, the oxygen will not leak. Instead, it enters the delivery tube 74 through the connecting disassembly head 72 and is finally delivered to the user through the nasal four-way connector 1. When the nasal four-way connector 1 needs to be replaced, it can be easily removed and replaced with a new nasal four-way connector using the threaded connection between the connecting disassembly sleeve 71 and the connecting disassembly head 72. This ensures normal oxygen delivery during use and facilitates maintenance and component replacement, meeting the needs for quick cleaning and replacement on the Qinghai-Tibet Railway train.

[0054] Compared with related technologies, the oxygen inhalation tube for the Qinghai-Tibet Railway provided by this utility model has the following beneficial effects:
