Description

An easy-to-install stainless steel pipe Technical Field

[0001] This utility model relates to the field of stainless steel pipe technology, specifically to a stainless steel pipe that is easy to install. Background Technology

[0002] Stainless steel pipes are made of stainless steel containing alloying elements such as chromium and nickel, which gives the pipes excellent corrosion resistance. Whether facing humid air, acidic or alkaline media, or complex and ever-changing outdoor environments, they can remain stable for a long time and are not easily rusted or corroded. In addition, they have excellent mechanical properties, high strength and good toughness, and can withstand great pressure and impact. They can play a stable role in high-pressure transportation, building structure support and other scenarios. They also have good processing performance. Furthermore, the smooth inner wall of stainless steel pipes reduces fluid transportation resistance, effectively reducing energy consumption. They are also hygienic and environmentally friendly, and are widely used in various fields such as food, medical and automotive.

[0003] Currently, when stainless steel pipes are connected and installed using their own connecting threads, the operation is difficult due to the long length of the pipes, often requiring multiple people to work together to complete the connection and installation. Therefore, we propose a stainless steel pipe that is easier to install. Summary of the Invention

[0004] The purpose of this utility model is to provide a stainless steel pipe that is easy to install. It has the advantages of facilitating the connection and installation of stainless steel pipes through threaded connections, improving the efficiency of stainless steel pipe connection and installation, and facilitating the subsequent disassembly of stainless steel pipes. It solves the problem that when stainless steel pipes are connected and installed through their own connecting threads, the operation of rotating the connection is difficult due to the long length of the stainless steel pipe, and often requires multiple people to work together to complete the connection and installation of stainless steel pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel pipe that is easy to install, comprising a stainless steel pipe body and a rotating ring. A first limiting ring is provided at the top end of the stainless steel pipe body. A rotating ring is slidably sleeved on the outer surface of the stainless steel pipe body near the top end. A second limiting ring is provided on the inner wall of the rotating ring near the lower surface. The inner wall of the rotating ring is provided with an internal thread. An annular groove is provided on the upper surface of the first limiting ring, and a sealing ring is provided inside the annular groove. An external thread is provided on the outer surface of the stainless steel pipe body near the lower surface. An annular protrusion is provided at the bottom end of the stainless steel pipe body.

[0006] Preferably, a fixing ring is fixedly sleeved on the outer surface of the stainless steel pipe body above the external thread. The outer surface of the fixing ring is provided with a plurality of first engagement grooves in a ring array at equal intervals. The outer surface of the rotating ring is provided with a plurality of second engagement grooves in a ring array at equal intervals. By cooperating with the first engagement grooves and the second engagement grooves, the stainless steel pipe body can be fixed and the rotating ring can be rotated by the wrench.

[0007] Preferably, the outer surface of the fixing ring is provided with a number of bent teeth in a ring array at equal intervals near the lower surface. After being bent, the bent teeth are inserted into the second engagement groove to restrict the rotation of the rotating ring, thereby preventing the connection between the stainless steel tube body and the rotating ring from becoming loose.

[0008] Preferably, the inner wall of the stainless steel pipe body is provided with a non-stick coating. The non-stick coating can prevent the flowing medium inside the stainless steel pipe body from adhering to the inner wall of the stainless steel pipe body, ensuring the effective flow area inside the stainless steel pipe body and improving the conveying efficiency of the stainless steel pipe body for the flowing medium.

[0009] Preferably, a sealing ring is movably fitted onto the outer surface of the stainless steel pipe body below the fixing ring. After the two stainless steel pipe bodies are connected and installed, the rotating ring and the fixing ring squeeze the sealing ring. The deformed sealing ring then seals the connection between the two stainless steel pipe bodies again, improving the sealing performance.

[0010] Preferably, a retaining ring is fixedly sleeved on the outer surface of the stainless steel tube body at a position below the rotating ring, and the retaining ring plays a role in limiting and blocking the rotating ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a stainless steel pipe body, a first limiting ring, a second limiting ring, a rotating ring, an internal thread, an external thread, an annular protrusion, an annular groove, and a sealing ring, achieves the effect of facilitating the connection and installation of stainless steel pipes through threaded connection, improving the connection and installation efficiency of stainless steel pipes, and facilitating the subsequent disassembly of stainless steel pipes. When connecting and installing two stainless steel pipe bodies, the annular protrusion is inserted into the annular groove. Rotating the rotating ring causes the rotating ring and the stainless steel pipe body to be fixedly connected through the internal and external threads, and the annular protrusion squeezes the sealing ring inside the annular groove to seal the connection between the two stainless steel pipe bodies, thus completing the connection and installation of the stainless steel pipe body components. Since the stainless steel pipe body itself does not need to rotate during the installation process, the difficulty of connecting and installing the stainless steel pipe body is reduced, and the connection and installation efficiency is improved.

[0013] 2. By setting a first engagement groove and a second engagement groove, this utility model achieves the effect of facilitating the fixing of the stainless steel pipe body and the rotation of the rotating ring. By cooperating with the first engagement groove and the second engagement groove, the stainless steel pipe body can be fixed and the rotating ring can be rotated by the wrench.

[0014] 3. This invention, by incorporating bending teeth, effectively prevents loosening of the connection between the two stainless steel pipe bodies. The bent teeth, after bending, insert into the second engagement groove to restrict the rotation of the rotating ring, thus preventing loosening between the stainless steel pipe body and the rotating ring. Furthermore, by including a sealing ring, after the two stainless steel pipe bodies are connected and installed, the rotating ring and the fixed ring compress the sealing ring. The deformed sealing ring then further seals the connection between the two stainless steel pipe bodies, improving the sealing performance. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] As shown in Figures 1-4, this utility model proposes an easy-to-install stainless steel pipe, including a stainless steel pipe body 2 and a rotating ring 4. A first limiting ring 9 is provided at the top of the stainless steel pipe body 2. The first limiting ring 9 and the stainless steel pipe body 2 are integrally formed. The outer diameter of the first limiting ring 9 is larger than the outer diameter of the stainless steel pipe body 2. The rotating ring 4 is slidably sleeved on the outer surface of the stainless steel pipe body 2 near the top.

A second limiting ring 15 is provided on the inner wall of the rotating ring 4 near the lower surface. The second limiting ring 15 and the rotating ring 4 are integrally formed. The inner diameter of the second limiting ring 15 is smaller than the outer diameter of the first limiting ring 9. The first limiting ring 9 and the second limiting ring 15 limit the rotating ring 4.

[0022] A retaining ring 3 is fixedly fitted onto the outer surface of the stainless steel pipe body 2 below the rotating ring 4. The retaining ring 3 limits and blocks the rotating ring 4, causing the rotating ring 4 to approach the top of the stainless steel pipe body 2. The inner wall of the rotating ring 4 is provided with an internal thread 14. The upper surface of the first limiting ring 9 is provided with an annular groove 10, and a sealing ring 11 is provided inside the annular groove 10. The outer surface of the stainless steel pipe body 2 is provided with an external thread 5 near the lower surface. The bottom end of the stainless steel pipe body 2 is provided with an annular protrusion 12, which is adapted to the annular groove 10. The inner wall of the stainless steel pipe body 2 is provided with a non-stick coating 8. The non-stick coating 8 can prevent the flowing medium inside the stainless steel pipe body 2 from adhering to the inner wall of the stainless steel pipe body 2, ensuring the effective flow area inside the stainless steel pipe body 2 and improving the conveying efficiency of the stainless steel pipe body 2 for the flowing medium.

[0023] When the two stainless steel pipe bodies 2 are connected and installed in this utility model, the annular protrusion 12 is inserted into the annular groove 10. The rotating ring 4 is rotated so that the rotating ring 4 and the stainless steel pipe body 2 are fixedly connected by the internal thread 14 and the external thread 5. The annular protrusion 12 also squeezes the sealing ring 11 inside the annular groove 10 to seal the connection between the two stainless steel pipe bodies 2. At the same time, the connection and installation of the stainless steel pipe bodies 2 are completed. Since the stainless steel pipe bodies 2 do not need to rotate during the installation process, the difficulty of connecting and installing the stainless steel pipe bodies 2 is reduced and the connection and installation efficiency is improved.
