A storage cylinder filled with a purification agent is installed inside the purification pipe. This invention features a novel structure, ingenious design, reasonable structure, and high safety, making it suitable for widespread application.

[0004] These connection methods have certain limitations. For example, flange connections require multiple bolts for fixing, making the installation process cumbersome and requiring tools, which increases installation costs and time. Therefore, it is necessary to provide a new, easy-to-install gas connection pipe to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a gas connection pipe that is easy to install. By setting a rotating collar and an internal threaded sleeve, and using the opposite external thread on the connecting sleeve, the operator can quickly connect and disconnect gas pipe one and gas pipe two by simply rotating the internal threaded sleeve. This eliminates the need for complicated tools, greatly reduces the difficulty of installation, shortens the installation time, and improves work efficiency.

[0006] To solve the above technical problems, the present invention provides an easy-to-install gas connection pipe comprising: a gas pipe one, a gas pipe two, and a sealing connection mechanism. The inner walls of the gas pipe one and the gas pipe two, which are close to each other, are provided with sealing grooves. The gas pipe one and the gas pipe two are connected and fixed by the sealing connection mechanism.

[0007] The sealing connection mechanism includes a connecting sleeve, a first sealing ring, two rotating collars, two internally threaded sleeves, two second sealing rings, two rubber rings, and two first through slots. The connecting sleeve is disposed between the first gas pipe and the second gas pipe. The inner walls of both ends of the connecting sleeve are provided with installation through slots. The first sealing ring is installed on the vent hole of the connecting sleeve. The two ends of the first sealing ring are respectively adapted to the sealing through slots on the first gas pipe and the second gas pipe.

[0008] Two rotating collars are respectively rotatably fitted onto the close ends of gas pipe one and gas pipe two, and two internally threaded sleeves are respectively fitted onto the two rotating collars.

[0009] As a further embodiment of this utility model, two sealing rings are respectively installed in two mounting slots on the connecting sleeve, and two rubber rings are respectively installed in two mounting slots on the connecting sleeve, wherein the rubber rings are adapted to the sealing rings.

[0010] As a further embodiment of this utility model, the space between the outer wall of the second sealing ring, the rubber ring and the first sealing ring forms a through slot one, the ends of the first air pipe and the second air pipe that are close to each other are respectively adapted to the two through slots one, and the two rubber rings are respectively adapted to the first air pipe and the second air pipe.

[0011] As a further embodiment of this utility model, the outer wall of the connecting sleeve is symmetrically provided with two opposite external threads, and the two internal threaded sleeves are respectively threadedly connected to the two ends of the connecting sleeve.

[0012] As a further embodiment of this utility model, the outer wall of the internal threaded sleeve is equipped with multiple protrusions, which are distributed in a ring array, and the gaps between the multiple protrusions can form a groove.

[0013] As a further embodiment of this utility model, the space between the outer wall of the second air pipe and the rotating collar and the inner wall of the internal threaded sleeve forms a through slot two, which is adapted to the connecting sleeve and the rubber ring.

[0014] Compared with related technologies, the gas connection pipe provided by this utility model, which is easy to install, has the following advantages:

[0015] 1. This utility model, by setting a rotating collar and an internal threaded sleeve, and utilizing the opposite external threads on the connecting sleeve, allows operators to quickly connect and disconnect air pipe one and air pipe two simply by rotating the internal threaded sleeve, without the need for complex tools. This greatly reduces the difficulty of installation, shortens the installation time, and improves work efficiency. The protrusion and groove design on the outer wall of the internal threaded sleeve further facilitates manual operation, and installation and disassembly can be easily completed even in environments with limited space.

[0016] 2. This utility model adopts a multi-seal structure of sealing ring one, sealing ring two and rubber ring. Sealing ring one cooperates with the sealing groove of the inner wall of gas pipe one and gas pipe two. Sealing ring two and rubber ring are tightly fitted to the outer wall of gas pipe in the installation groove, forming multiple sealing defenses, effectively preventing gas leakage. The multi-seal structure works together to adapt to gas transmission under different pressure environments, improving the sealing reliability and stability of the connecting pipe.

[0017] 3. This utility model allows for flexible rotation of the rotating collar fitted onto the gas pipeline. At the same time, the threaded connection between the internal threaded sleeve and the connecting sleeve has good self-locking properties, ensuring that the connected gas pipeline will not loosen due to factors such as vibration and pressure changes during long-term use, thereby improving the safety and stability of the entire gas transmission system.

[0024] Please refer to the following: Figures 1 to 4 ,in, Figure 1 This is a three-dimensional schematic diagram of the present invention; Figure 2 for Figure 1 Schematic diagram of cross-section Figure 1 ; Figure 3 for Figure 2 A front view structural diagram; Figure 4 for Figure 1 Schematic diagram of cross-section Figure 2The easy-to-install gas connection pipe includes: gas pipe 1, gas pipe 2, and a sealing connection mechanism. The inner walls of the gas pipe 1 and gas pipe 2, which are close to each other, are provided with sealing grooves 100. The gas pipe 1 and gas pipe 2 are connected and fixed by the sealing connection mechanism.

[0025] The sealing connection mechanism includes a connecting sleeve 3, a sealing ring 4, two rotating collars 5, two internally threaded sleeves 6, two sealing rings 7, two rubber rings 8, and two through slots 9. The connecting sleeve 3 is disposed between the gas pipe 1 and the gas pipe 2. The inner walls of both ends of the connecting sleeve 3 are provided with mounting through slots. The sealing ring 4 is installed on the vent hole of the connecting sleeve 3. The two ends of the sealing ring 4 are respectively adapted to the sealing through slots 100 on the gas pipe 1 and the gas pipe 2.

[0026] Two rotating collars 5 are respectively rotatably sleeved on the close ends of gas pipe 1 and gas pipe 2, and two internally threaded sleeves 6 are respectively sleeved and installed on the two rotating collars 5.

[0027] Two sealing rings 7 are respectively installed in two mounting slots on the connecting sleeve 3, and two rubber rings 8 are respectively installed in two mounting slots on the connecting sleeve 3. The rubber rings 8 are adapted to the sealing rings 7.

[0028] The space between the outer walls of the second sealing ring 7, the rubber ring 8 and the first sealing ring 4 forms a through slot 9. The ends of the first air pipe 1 and the second air pipe 2 that are close to each other are respectively adapted to the two through slots 9, and the two rubber rings 8 are respectively adapted to the first air pipe 1 and the second air pipe 2.

[0029] The outer wall of the connecting sleeve 3 is symmetrically provided with two opposite external threads 31, and the two internal thread sleeves 6 are respectively threaded to the two ends of the connecting sleeve 3.

[0030] The outer wall of the internal threaded sleeve 6 is equipped with a plurality of protrusions 10, which are arranged in a ring array, and the gaps between the plurality of protrusions 10 can form a groove 11.

[0031] The space between the outer wall of the second gas pipe 2 and the inner wall of the rotating collar 5 and the inner wall of the internal threaded sleeve 6 forms a through slot 2, which is adapted to the connecting sleeve 3 and the rubber ring 8.

[0032] The working principle of the gas connection pipe provided by this utility model, which is easy to install, is as follows:

[0033] First step: Align the ends of gas pipe 1 and gas pipe 2 that need to be connected with the two ends of the connecting sleeve 3 respectively, and insert the ends of gas pipe 1 and gas pipe 2 that are close to each other into the through slots 9 formed between the outer walls of sealing ring 2 7, rubber ring 8 and sealing ring 4 at both ends of the connecting sleeve 3. At this time, the rubber ring 8 is tightly fitted with the outer walls of gas pipe 1 and gas pipe 2, which plays a role in initial positioning and initial sealing.

[0034] Second step: Rotate the internal threaded sleeve 6. Since the outer wall of the connecting sleeve 3 is symmetrically provided with two opposite external threads 31, the two internal threaded sleeves 6 are respectively screwed into the external threads 31 at both ends of the connecting sleeve 3 (threaded connection). Therefore, when the internal threaded sleeve 6 is rotated, under the action of the threaded transmission, the two internal threaded sleeves 6 will move relative to each other or in opposite directions along the axial direction of the connecting sleeve 3. When it is necessary to connect air pipe 1 and air pipe 2, the two internal threaded sleeves 6 are moved towards the middle of the connecting sleeve 3, thereby pushing the rotating collar 5 to drive air pipe 1 and air pipe 2 to move towards the connecting sleeve 3.

[0035] Third step: As air pipe 1 and air pipe 2 move, the sealing grooves 100 on the inner walls of air pipe 1 and air pipe 2 tightly engage with the sealing rings 4 installed at the vent holes on the connecting sleeve 3. The two ends of the sealing rings 4 are respectively embedded in the sealing grooves 100, forming the first seal. At the same time, the sealing rings 7 and rubber rings 8 installed in the grooves at both ends of the connecting sleeve 3 are further deformed under the compression of the moving air pipes 1 and 2, filling the gap between the connecting sleeve 3 and the air pipes 1 and 2, forming a multi-seal structure. When the internal threaded sleeve 6 moves to the appropriate position, it stops rotating. At this time, the grooves 11 formed by the protrusions 10 on the outer wall of the internal threaded sleeve 6 facilitate the operator to apply force to rotate it. Due to the self-locking property of the threaded connection, the entire connection structure is firmly fixed, completing the connection and sealing of air pipe 1 and air pipe 2.
