Description

Technical Field

[0001] This utility model relates to the field of composite PE pipe technology, and in particular to an antibacterial and wear-resistant composite PE pipe. Background Technology

[0002] In modern industry and daily life, PE pipes are widely used in water supply and drainage, gas transmission, and chemical fluid transportation due to their excellent corrosion resistance, flexibility, and cost advantages. However, traditional PE pipes have many problems in actual use. In terms of connection, existing PE pipe connection methods often suffer from complex operation and poor sealing. Some connection structures rely solely on simple socket or glue bonding. During long-term use, under the influence of fluid pressure, temperature changes, and external vibrations, the connection is prone to loosening and leakage. This not only wastes resources but may also cause safety accidents, such as gas leaks leading to explosions or toxic liquid leaks polluting the environment. Furthermore, the complex connection process increases installation time and labor costs, reducing project efficiency. In terms of filtration and antibacterial properties, impurities easily accumulate inside the PE pipes used to transport fluids. These impurities can cause wear on the inner wall of the pipe during fluid flow, shortening the pipe's service life. Therefore, we have introduced a new antibacterial and wear-resistant composite PE pipe. Utility Model Content

[0003] The main purpose of this utility model is to provide an antibacterial and wear-resistant composite PE pipe, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An antibacterial and wear-resistant composite PE pipe includes a first PE pipe and a second PE pipe, which are arranged in a left-right correspondence. Six transverse wear-resistant strips are provided on the outer surfaces of both the first and second PE pipes. Several annular wear-resistant strips are provided between the outer surfaces of the six transverse wear-resistant strips on the left and the six on the right. A first fixing ring is provided on the right side of the outer surface of the second PE pipe. Fixing seats are provided on both the front and rear sides of the outer surface of the first fixing ring, and fixing holes are provided on the inner walls of both fixing seats. A connecting assembly is provided on the left side of the outer surface of the first PE pipe. An antibacterial inner tube is provided on the inner surface of both the first and second PE pipes, and a filter assembly is movably installed on the inner surface of the antibacterial inner tube.

[0006] Preferably, the connecting assembly includes a second fixing ring, with mounting blocks provided on both the front and rear of the outer surface of the second fixing ring. The left end of the second fixing ring has six insertion holes and a sealing groove. The right end of the first fixing ring has a sealing gasket and six insertion rods. Corresponding blocks are provided on the front and rear of the left ends of the two mounting blocks. Springs are fixedly installed on the front and rear interior sides of the two corresponding blocks via inner grooves. Push plates are movably installed on the front and rear interior sides of the two corresponding blocks via inner grooves. Limiting protrusions are provided on the ends of the two push plates furthest from the springs.

[0007] Preferably, the first fixing ring and the second fixing ring are positioned left and right respectively, and the first fixing ring and the second fixing ring are sealed together by a sealing groove and a sealing gasket.

[0008] By adopting the above technical solution, a tight sealing structure can be formed between the first fixing ring and the second fixing ring through the cooperation of the sealing groove and the sealing gasket.

[0009] Preferably, the six insertion rods correspond to the positions of the six insertion holes, and the six insertion rods are movably engaged inside the six insertion holes.

[0010] By adopting the above technical solution, the six plugs are correspondingly engaged with the plug holes, which can provide a stable mechanical connection between the components, effectively disperse stress, prevent the components from loosening or separating, and ensure the integrity and stability of the pipe structure.

[0011] Preferably, the corresponding block is movably engaged inside the fixed base, and the limiting protrusion is movably engaged inside the fixed hole by a spring and a push plate.

[0012] By adopting the above technical solution, the setting of the spring and the push plate enables the limiting protrusion to be adjusted and fixed according to actual needs. When it is necessary to install or disassemble the component, the spring can be compressed by the push plate to make the limiting protrusion disengage from the fixing hole, which facilitates the movement of the component. After installation, the spring returns to its original position and the limiting protrusion is re-engaged into the fixing hole, so as to achieve reliable limiting and fixing of the component.

[0013] Preferably, the filter assembly includes a mounting ring, a filter cylinder is provided at the left end of the mounting ring, six limiting posts are provided at the left end of the mounting ring, a mounting groove is provided at the right end of the antibacterial inner tube, six limiting holes are provided on the inner left wall of the mounting groove, and a pull block is provided on the front right side of the inner surface of the filter cylinder.

[0014] By adopting the above technical solution—the coordinated design of the mounting ring, filter cartridge, limiting posts, mounting groove, and limiting holes—the filter assembly can be quickly and accurately installed and positioned with the antibacterial inner tube. The six limiting posts and limiting holes are correspondingly engaged, ensuring the stability and accuracy of the filter assembly installation, preventing the filter cartridge from shifting or rotating during use, and ensuring the reliability of the filtration effect.

[0015] Preferably, the filter cartridge is movably engaged with the limiting post inside the mounting groove and the limiting hole.

[0016] By adopting the above technical solution—the movable snap-fit ​​connection between the filter cartridge and the mounting groove and limiting hole—the installation process of the filter assembly is simplified and the installation efficiency is improved.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The connection between the first PE pipe and the second PE pipe is achieved through the connecting components. The corresponding snap-fit ​​of the plug and the plug hole, combined with the sealing structure of the sealing gasket and the sealing groove, allows the two pipes to quickly form a sealed connection after initial positioning, effectively preventing fluid leakage. At the same time, through the cooperation of the corresponding block, spring, push plate and limiting protrusion, after the snap-fit ​​is completed, the elastic return of the spring can firmly snap the limiting protrusion into the fixing hole, so that the connection structure remains stable when faced with external forces such as tension and vibration. This not only simplifies the connection operation process and reduces the installation difficulty, but also improves the reliability of the connection parts, reduces the risk of leakage caused by loose connection, and ensures the stability and safety of the pipes during long-term use.

[0019] 2. By cooperating with the limiting post of the mounting ring and the limiting hole of the antibacterial inner tube, the filter cartridge can be precisely positioned and installed, ensuring its stable operation inside the pipe. This effectively intercepts impurities in the fluid, preventing impurities from abrading the inner wall of the pipe, thus protecting the antibacterial performance of the antibacterial inner tube and extending the service life of the pipe. The pull block set on the inner surface of the filter cartridge allows the operator to easily remove it from the mounting slot when cleaning or replacing the filter cartridge, greatly simplifying the maintenance process, reducing maintenance costs and time costs, and facilitating users to perform daily maintenance on the pipe, continuously ensuring the cleanliness of the fluid inside the pipe and the good performance of the pipe.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] An antibacterial and wear-resistant composite PE pipe includes a first PE pipe 1 and a second PE pipe 2, which are arranged in a left-right correspondence. The outer surfaces of the first PE pipe 1 and the second PE pipe 2 are each provided with six transverse wear-resistant strips 3. The outer surfaces of the six transverse wear-resistant strips 3 on the left and the six transverse wear-resistant strips on the right are each provided with a number of annular wear-resistant strips 4. The right side of the outer surface of the second PE pipe 2 is provided with a first fixing ring 5. The front and rear sides of the outer surface of the first fixing ring 5 are provided with fixing seats 6. The inner walls of the two fixing seats 6 are provided with fixing holes 7. The left side of the outer surface of the first PE pipe 1 is provided with a connecting component 8. The inner surfaces of the first PE pipe 1 and the second PE pipe 2 are each provided with an antibacterial inner tube 9. A filter component 10 is movably installed on the inner surface of the antibacterial inner tube 9.

[0030] In this embodiment, the connecting component 8 includes a second fixing ring 80. Mounting blocks 81 are provided on both the front and rear sides of the outer surface of the second fixing ring 80. Six insertion holes 82 are provided on the left end of the second fixing ring 80, and a sealing groove 83 is provided on the left end. A sealing gasket 84 is provided on the right end of the first fixing ring 5, and six insertion rods 85 are provided on the right end of the first fixing ring 5. Corresponding blocks 86 are provided on the front and rear sides of the left ends of the two mounting blocks 81. Springs 87 are fixedly installed on the front and rear sides of the interior of the two corresponding blocks 86 via inner grooves. Both the inner rear and the inner rear are equipped with push plates 88 that are movably installed through the inner groove. Each push plate 88 has a limiting protrusion 89 at the end away from the spring 87. The positions of the first fixing ring 5 and the second fixing ring 80 are corresponding left and right. The first fixing ring 5 and the second fixing ring 80 are sealed together by the sealing groove 83 and the sealing gasket 84. The six insertion rods 85 correspond to the positions of the six insertion holes 82 respectively. The six insertion rods 85 are movably engaged inside the six insertion holes 82. The corresponding block 86 is movably engaged inside the fixing seat 6. The limiting protrusion 89 is movably engaged inside the fixing hole 7 by the spring 87 and the push plate 88.

[0031] Through the above scheme: when it is necessary to connect the first fixing ring 5 and the second fixing ring 80, first align the six inserts 85 of the first fixing ring 5 with the six holes 82 of the second fixing ring 80, insert the inserts 85 into the holes 82 to achieve initial positioning, and ensure that the positions of the first fixing ring 5 and the second fixing ring 80 are aligned left and right. The sealing gasket 84 at the right end of the first fixing ring 5 and the sealing groove 83 at the left end of the second fixing ring 80 cooperate with each other. As the inserts 85 and the holes 82 are engaged, the sealing gasket 84 is embedded in the sealing groove 83, forming a tight sealing structure to prevent fluid leakage and ensure the sealing of the fluid transport inside the pipe. The corresponding block 86 on the mounting block 81 is inserted into the fixed seat 6. At this time, the push plate 88 is pressed, and the push plate 88 moves inward against the elastic force of the spring 87, which drives the limiting protrusion 89 to move into the corresponding block 86. After the corresponding block 86 is accurately inserted into the fixed seat 6, the push plate 88 is released, the spring 87 returns to its deformation, pushes the push plate 88, and then pushes the limiting protrusion 89 into the fixed hole 7, so that the corresponding block 86 and the fixed seat 6 are firmly connected, and the first fixed ring 5 and the second fixed ring 80 are stably connected, effectively dispersing the stress under the action of external force and ensuring the stability of the connection structure under tensile, vibration and other working conditions.

[0032] In this embodiment, the filter assembly 10 includes a mounting ring 101, a filter cylinder 102 is provided at the left end of the mounting ring 101, six limiting posts 103 are provided at the left end of the mounting ring 101, a mounting groove 104 is provided at the right end of the antibacterial inner tube 9, six limiting holes 105 are provided on the inner left wall of the mounting groove 104, and a pull block 106 is provided on the front right side of the inner surface of the filter cylinder 102; the filter cylinder 102 is movably engaged with the mounting groove 104 and the limiting holes 105 through the filter cylinder 102 and the limiting posts 103.

[0033] Through the above scheme: When installing the filter assembly 10, align the six limiting posts 103 on the left end of the mounting ring 101 with the six limiting holes 105 on the left wall of the mounting groove 104 on the right end of the antibacterial inner tube 9, so that the limiting posts 103 are inserted into the limiting holes 105. As the limiting posts 103 are gradually inserted into the limiting holes 105, the mounting ring 101 drives the filter cartridge 102 to gradually enter the mounting groove 104 until the filter cartridge 102 and the limiting posts 103 are completely engaged inside the mounting groove 104 and the limiting holes 105, thus completing the installation and positioning of the filter assembly 10 and the antibacterial inner tube 9, ensuring that the filter cartridge 102 is safe for use. There will be no shifting or rotation during the process. When the fluid passes through the pipe, the fluid enters the filter cartridge 102. The filter cartridge 102 intercepts and filters the impurities in the fluid, ensuring that the fluid entering the antibacterial inner tube 9 is clean, reducing the wear of impurities on the inner wall of the tube, and protecting the antibacterial performance and service life of the antibacterial inner tube 9. When it is necessary to clean or replace the filter cartridge 102, pull the pull block 106 on the front right side of the inner surface of the filter cartridge 102. Use the pull block 106 to easily pull the filter cartridge 102 out of the mounting groove 104, which is convenient for users to maintain and care for the filter assembly 10 and maintain the effectiveness of the filtration effect.

[0034] It should be noted that this utility model is an antibacterial and wear-resistant composite PE pipe. During use, when connecting, first, align the second fixing ring 80 in the connecting assembly 8 of the first PE pipe 1 with the first fixing ring 5 of the second PE pipe 2, so that the six insertion rods 85 on the right end of the first fixing ring 5 are inserted into the six insertion holes 82 on the left end of the second fixing ring 80 to complete the initial positioning. At this time, the sealing gasket 84 on the right end of the first fixing ring 5 is embedded in the sealing groove 83 on the left end of the second fixing ring 80 to form a sealing structure and prevent fluid leakage. Next, press the push plate 88 in the corresponding block 86 on the mounting block 81 of the second fixing ring 80 to push the limiting protrusion 89 to move inward. After the corresponding block 86 is inserted into the fixing seat 6 of the first fixing ring 5, release the push plate 88. The spring 87 pushes the limiting protrusion 89 into the fixing hole 7 of the fixing seat 6 to achieve a stable connection between the first PE pipe 1 and the second PE pipe 2, thus filtering the fluid. The six limiting posts 103 on the left end of the mounting ring 101 of component 10 are aligned with the six limiting holes 105 on the left wall of the mounting groove 104 on the right end of the antibacterial inner tube 9. The limiting posts 103 are inserted, so that the mounting ring 101 drives the filter cartridge 102 into the mounting groove 104, completing the positioning and installation of the filter component 10 and the antibacterial inner tube 9, ensuring that the filter cartridge 102 is stable and does not shift. When the composite PE pipe is used, the transverse wear-resistant strips 3 and annular wear-resistant strips 4 on the outer surface of the first PE pipe 1 and the second PE pipe 2 resist external friction and improve the wear resistance of the pipe. The fluid in the pipe is filtered by the filter cartridge 102, and after intercepting impurities, it enters the antibacterial inner tube 9, reducing the wear of impurities on the inner wall of the pipe and ensuring the antibacterial performance of the antibacterial inner tube 9. When maintenance is required, the pull block 106 on the front right side of the inner surface of the filter cartridge 102 can be pulled to remove the filter cartridge 102 from the mounting groove 104 for easy cleaning or replacement and to maintain the filtration effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
