Description

Technical Field

[0001] This utility model relates to the field of connecting device technology, specifically to a ceramic insulated air-sealed short section. Background Technology

[0002] Short sections are commonly used fittings in industrial pipeline connections. Common types include threaded short sections, which come in several varieties such as double-ended male thread, single-ended male thread, and flat-ended male thread. There are also short sections that connect with flanges. Short sections are divided into tubing short sections and sleeve short sections. In pipe fitting connections, flanged short sections are commonly used in conjunction with flanges. Specifically, they are fitted inside the flange, allowing the flange to move. Tubing short sections are simply short sections of tubing. Compared to tubing, they are the same except for their length.

[0003] When using short sections to connect pipes, threaded connections are commonly used. However, threaded connections require a lot of labor, and the threads wear down over time, leading to high labor intensity and poor user experience. Furthermore, since the short section lacks an external cushioning structure, it can bend or break when subjected to impact, compromising its lifespan and resulting in wasted costs. To address this, a ceramic-insulated, airtight short section is now being introduced. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a ceramic insulating gap-free short section, which has the advantages of saving labor, providing good user experience, ensuring service life, and saving costs, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a ceramic insulating and airtight short section, including a tube body, an insulating layer fixedly sleeved inside the inner cavity of the tube body, and a sealing layer fixedly sleeved on the inner wall of the insulating layer. Limiting grooves are formed in the inner walls of both ends of the tube body, and a spring is fixedly connected to the top surface of the limiting groove. A spring button is fixedly connected to one end of the spring, and one end of the spring button passes through the limiting groove and extends into the inner cavity of the sealing layer. A pull rod is fixedly connected to the top surface of the spring button, and one end of the pull rod passes through the limiting groove and extends to the outside of the tube body. A pipe is placed on the right side of the tube body.

[0006] Preferably, a protective layer is fixedly connected to the outer surface of the tube body, and a sleeve is fixedly connected to the inner side of the protective layer. An elastic element is fixedly connected to the side of the inner cavity of the sleeve. A movable plate is fixedly connected to one end of the elastic element, and a telescopic rod is fixedly connected to the side of the movable plate. One end of the telescopic rod extends to the outside of the sleeve and is fixedly connected to the tube body.

[0007] Preferably, the pipe has a button hole that matches the spring button, and the button hole and the spring button are in a snap-fit ​​relationship.

[0008] Preferably, the spring button is movably connected to the limiting groove, and the distance from the spring button to the side of the limiting groove is equal to the length of the spring.

[0009] Preferably, the movable plate is movably sleeved with the inner cavity of the sleeve, and the distance from the movable plate to the side of the inner cavity of the sleeve is equal to the length of the elastic element.

[0010] Preferably, the number of sleeves is ten, and the ten sleeves are evenly distributed on both sides of the outer surface of the tube.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model replaces threaded connection with pipe clamping by using a spring button on the pipe body and a button hole on the pipe body to clamp the pipe inside the pipe body through the snap-fit ​​between the spring button and the button hole. This avoids the problems of high labor intensity and poor user experience caused by threaded connection, which requires a lot of labor and the threads will wear down after long-term use. This invention saves labor while improving the user experience.

[0013] 2. This utility model adds a buffer device to the outside of the short section. By utilizing the interaction between the moving plate and the sleeve, the elastic force of the elastic element drives the telescopic rod to move. The moving telescopic rod buffers the impact force, avoiding the problem that the short section would bend or break when it is subjected to impact force due to the lack of a buffer structure on the outside of the short section. This would result in the short section's service life being compromised and costs being wasted. The invention ensures the short section's service life while saving costs. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-3A ceramic insulating and airtight short section includes a tube body 1. An insulating layer 2 is fixedly sleeved inside the inner cavity of the tube body 1, and a sealing layer 3 is fixedly sleeved on the inner wall of the insulating layer 2. Limiting grooves 10 are formed in the inner walls at both ends of the tube body 1, and springs 11 are fixedly connected to the top surface of the limiting grooves 10. A spring button 4 is fixedly connected to one end of the spring 11. The spring button 4 is movably sleeved with the limiting groove 10. The distance from the spring button 4 to the side of the limiting groove 10 is equal to the length of the spring 11, so that the spring button 4 can move smoothly within the limiting groove 10. At the same time, the spring 11 is initially in a normal state. Through the elastic force of the spring 11, the spring button 4 can be engaged and disengaged from the button hole 9. One end of the spring button 4 passes through the limiting groove 10 and extends into the inner cavity of the sealing layer 3. A pull rod 12 is fixedly connected to the top surface of the spring button 4. One end of the pull rod 12 passes through the limiting groove 10 and extends to the outside of the pipe body 1. A pipe 8 is placed on the right side of the pipe body 1. A button hole 9 that matches the spring button 4 is opened on the pipe 8. The button hole 9 and the spring button 4 are in a snap-fit ​​relationship. By utilizing the interaction between the spring button 4 on the pipe body 1 and the button hole 9 on the pipe 8, the pipe 8 is snapped into the inside of the pipe body 1 through the snap-fit ​​between the spring button 4 and the button hole 9. This avoids the use of threaded connection, which requires a lot of labor from workers and the threads will wear out after long-term use, resulting in labor... To address the issue of high strength but poor user experience, and to improve user experience while saving labor, a protective layer 5 is fixedly connected to the outer surface of the pipe body 1, and ten sleeves 6 are fixedly connected to the inner side of the protective layer 5. These ten sleeves 6 are evenly distributed on both sides of the outer surface of the pipe body 1, ensuring even force distribution on both sides of the pipe body 1 and reducing the problem of pipe body 1 tilting. Simultaneously, the sleeves 6 can buffer impact forces from multiple directions, improving the buffering effect. Furthermore, an elastic element 13 is fixedly connected to the side of the inner cavity of the sleeve 6, and a movable plate 14 is fixedly connected to one end of the elastic element 13. The movable plate 14 is movably sleeved with the inner cavity of the sleeve 6. The distance from the moving plate 14 to the inner side of the sleeve 6 is equal to the length of the elastic element 13. By utilizing the interaction between the moving plate 14 and the sleeve 6, the elastic force of the elastic element 13 extends and retracts, driving the telescopic rod 7 to extend and retract. The moving telescopic rod 7 is used to buffer the impact force, avoiding the problem that the short section is bent or broken when it is subjected to impact force due to the lack of a buffer structure on the outside of the short section, which would lead to the inability to guarantee the service life of the short section and waste costs. This ensures the service life of the short section while saving costs. In addition, the side of the moving plate 14 is fixedly connected to the telescopic rod 7, and one end of the telescopic rod 7 extends to the outside of the sleeve 6 and is fixedly connected to the tube body 1.

[0020] Working principle: In use, first pull the lever 12 to move the spring button 4. While the spring button 4 moves in the limiting groove 10, it compresses the spring 11 to generate elastic force. At this time, the pipe 8 is placed into the inner cavity of the pipe body 1. Release the lever 12, and the spring 11 restores its elastic force, causing the spring button 4 to spring into the button hole 9 on the pipe 8 for fixation. This is how the connection between the pipe 8 and the short section is completed. When subjected to impact force, the impact force compresses the telescopic rod 7, and the telescopic rod 7 compresses the moving plate 14. While the moving plate 14 moves in the sleeve 6, it compresses the elastic element 13 to generate elastic force. The elastic force of the elastic element 13 drives the moving plate 14 to move in the opposite direction. The moving plate 14 drives the telescopic rod 7 to move in the opposite direction. The impact force is buffered by the telescopic rod 7 moving in the opposite direction.
