[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1-5 As shown, a PE electromagnetic hot-melt pipe assembly includes a pipe body 1, with connectors 2 inserted at both ends of the pipe body 1. The pipe body 1 has an outer wall ring 3 and a positioning connector 4. The connector 2 abuts against the outer wall ring 3. The connector 2 has a large-area wall surface hot-melt connection structure 5 and a positioning end hot-melt connector 6 inside. The positioning connector 4 is inserted into the connector 2 and is positioned opposite to the positioning end hot-melt connector 6. The outer wall ring 3 has an auxiliary hot-melt fixing component 7. The connector 2 also has an embedded heat-conducting component 8, which corresponds to the position of the positioning end hot-melt connector 6.

[0028] In this embodiment, the pipe body 1 is the main part of the pipe. The connector 2 is used to connect different pipe bodies 1. The outer wall ring 3 is fixed on the pipe body 1. The connector 2 is sleeved on the end of the pipe body 1 and tightly abuts against the outer wall ring 3, playing a role in initial positioning and sealing. The positioning connector 4 is inserted into the connector 2 from the pipe body 1 and is precisely aligned with the positioning end heat fusion connector 6 inside the connector 2, providing a positioning reference for subsequent heat fusion connection. The auxiliary heat fusion fixing part 7 is located inside the outer wall ring 3 and assists the connector 2 in connecting with the pipe body 1 during the heat fusion process. The embedded heat-conducting component 8 is set inside the connector 2 and corresponds to the position of the positioning end heat fusion connector 6. It is used to conduct heat. This structural design makes the connection between the pipe body 1 and the connector 2 more stable and accurate in positioning, which is conducive to subsequent heat fusion connection operations. Multiple components work together to improve the reliability of the connection. The auxiliary heat fusion fixing component 7 and the embedded heat-conducting component 8 ensure the quality of the heat fusion connection from the aspects of auxiliary connection and heat conduction, respectively. The embedded heat-conducting component 8 has better thermal conductivity, which allows the heat fusion to be closer to the inside, avoiding affecting the internal thread of the connector.

[0029] Combination Figures 1-5As shown, the large-area wall surface hot-melt connection structure 5 includes a hot-melt inner cavity 9 disposed in the connector 2. The hot-melt inner cavity 9 is provided with a hot-melt ring sleeve 10 made of electromagnetic induction heating material. The hot-melt ring sleeve 10 has a hollow part 11 inside.

[0030] Specifically, the hot-melt inner cavity 9 provides installation space for the hot-melt ring sleeve 10. The hot-melt ring sleeve 10 is tightly installed in the hot-melt inner cavity 9. When the external electromagnetic induction equipment is working, the hot-melt ring sleeve 10, as the main body of electromagnetic induction heating, generates heat by utilizing its own properties made of electromagnetic induction heating material to heat-melt the connection part of the pipe body 1 and the connector 2. The hollow part 11 is distributed inside the hot-melt ring sleeve 10, affecting the heat transfer and distribution. The hot-melt ring sleeve 10 achieves rapid hot-melt connection through electromagnetic induction heating. Compared with the traditional heating method, no additional heating equipment is required, making the operation more convenient. The design of the hollow part 11 can optimize the heat distribution, making the hot-melt more uniform, avoiding local overheating or undercooling, and improving the welding quality.

[0031] Combination Figure 2 , Figure 5 As shown, the hollowed-out portion 11 includes a first wall hot-melt hole 12 and a second wall hot-melt hole 13 disposed within the hot-melt ring sleeve 10. The first wall hot-melt hole 12 and the second wall hot-melt hole 13 are staggered, and the diameter of the first wall hot-melt hole 12 is larger than the diameter of the second wall hot-melt hole 13.

[0032] In this embodiment, the first wall surface hot-melt hole 12 and the second wall surface hot-melt hole 13 are both located inside the hot-melt ring sleeve 10, and are arranged alternately. The design of different hole diameters allows heat to be transferred to the connection part of the pipe body 1 and the connector 2 at different rates and in different ways through the different sized and staggered channels when the hot-melt ring sleeve 10 heats up. The staggered arrangement of the first wall surface hot-melt holes 12 and the second wall surface hot-melt holes 13 with different hole diameters enables the heat to be distributed more evenly at the connection part, effectively solving the welding quality problem caused by uneven heat distribution in traditional hot-melt connections, and further improving the reliability and stability of the connection.

[0033] The hot-melt inner cavity 9 is provided with a ring anti-over-position part 14, which abuts against the hot-melt ring 10.

[0034] In this embodiment, the anti-over-displacement part 14 of the ring is installed in the hot-melt inner cavity 9 and is in close contact with the hot-melt ring 10. When the hot-melt ring 10 is subjected to thermal expansion and contraction or external force during the hot-melt process, the anti-over-displacement part 14 can limit its displacement, ensuring that the hot-melt ring 10 is always in the correct working position, preventing the hot-melt ring 10 from being excessively displaced in the hot-melt inner cavity 9, ensuring that the hot-melt ring 10 is tightly fitted with the connection part of the pipe body 1 and the connector 2, maintaining a stable hot-melt effect, thereby ensuring the welding quality.

[0035] Combination Figure 2 As shown, the ring anti-over-position part 14 includes a ring anti-over-position block 15 disposed in the hot-melt inner cavity 9. The ring anti-over-position block 15 abuts against the hot-melt ring 10 and the ring anti-over-position block 15 is staggered with the hot-melt hole 12 on the first wall surface.

[0036] In this embodiment, the anti-over-displacement block 15 is fixed inside the hot-melt inner cavity 9 and abuts against the outer wall of the hot-melt ring 10, thereby preventing the hot-melt ring 10 from shifting. At the same time, the anti-over-displacement block 15 is staggered with the hot-melt holes 12 on the first wall surface, avoiding adverse effects on the heat transfer and distribution of the hot-melt holes 12 on the first wall surface. While ensuring that the displacement of the hot-melt ring 10 is limited, the heat transfer and uniform distribution of the hot-melt holes 12 on the first wall surface are not interfered with, thus ensuring the smooth progress of the hot-melt connection process and the connection quality.

[0037] The positioning connector 4 includes a positioning insert ring 16 disposed on the pipe body 1, and a positioning ring groove 17 is provided in the connector 2. The positioning insert ring 16 is engaged with the positioning ring groove 17, and the positioning end heat fusion connector 6 is located in the positioning ring groove 17.

[0038] In this embodiment, the positioning ring 16 is fixed on the pipe body 1, and the positioning ring groove 17 is opened in the connector 2. During installation, the positioning ring 16 is inserted into the positioning ring groove 17 to achieve the initial positioning of the pipe body 1 and the connector 2. The positioning end heat fusion connector 6 is located in the positioning ring groove 17. After the positioning ring 16 is inserted, it is directly opposite the positioning end heat fusion connector 6, providing positioning and heat fusion foundation for subsequent heat fusion connection. The snap-fit ​​cooperation between the positioning ring 16 and the positioning ring groove 17 makes the installation of the pipe body 1 and the connector 2 more convenient and accurate, improving construction efficiency. At the same time, it provides precise positioning for the heat fusion connection between the positioning end heat fusion connector 6 and the positioning ring 16, enhancing the firmness of the connection.

[0039] The positioning end hot-melt connector 6 includes a first heating ring 18 made of electromagnetic induction heating material disposed in the positioning ring groove 17, and the first heating ring 18 is disposed opposite to the positioning insert ring 16.

[0040] In this embodiment, the first heating ring 18 is installed in the positioning ring groove 17 and is precisely aligned with the positioning insert 16 inserted into the positioning ring groove 17. When subjected to external electromagnetic induction, the first heating ring 18 heats up, causing the contact part between the positioning insert 16 and the connector 2 to be thermally fused together. The thermal fusion connection between the positioning insert 16 and the connector 2 is achieved through electromagnetic induction heating, which further enhances the stability of the connection part between the pipe body 1 and the connector 2, prevents relative displacement between the two, and improves the reliability of the connection.

[0041] Combination Figure 4As shown, the first heating ring 18 has a plurality of first ring hollow holes 19 arranged in a ring array along the center point of the first heating ring 18.

[0042] In this embodiment, the first ring body hollow holes 19 are evenly distributed inside the first heating ring body 18 and arranged in a ring array around the center point of the first heating ring body 18. When the first heating ring body 18 heats up, the first ring body hollow holes 19 can change the heat transfer path and distribution state. The setting of the first ring body hollow holes 19 can optimize the heat distribution of the first heating ring body 18, making the connection part between the positioning insert ring 16 and the connector 2 more evenly heated, while reducing the weight of the first heating ring body 18 and reducing material costs.

[0043] Combination Figure 1 , Figure 2 As shown, the auxiliary hot-melt fixing component 7 includes a second heating ring 20 made of electromagnetic induction heating material disposed inside the outer wall ring 3. The second heating ring 20 has a plurality of second ring hollow holes 21 arranged in a ring array along the center point of the second heating ring 20.

[0044] In this embodiment, the second heating ring 20 is installed inside the outer ring 3. When subjected to external electromagnetic induction, the second heating ring 20 heats up, providing heat-fusion assistance to fix the contact area between the connector 2 and the pipe body 1. The perforated holes 21 of the second ring are evenly distributed inside the second heating ring 20, arranged in a ring array around the center point of the second heating ring 20, affecting the heat transfer and distribution. The second heating ring 20 heats up through electromagnetic induction, assisting the connection between the connector 2 and the pipe body 1, enhancing the connection's firmness. The perforated holes 21 of the second ring optimize the heat distribution, making the connection area heatd evenly, improving the welding quality, and at the same time reducing the weight of the second heating ring 20, thus reducing costs.

[0045] Combination Figure 2 As shown, the embedded heat-conducting component 8 includes a metal heat-conducting sleeve 22 disposed in the connector 2, and the metal heat-conducting sleeve 22 corresponds to the position of the first heating ring 18.

[0046] In this embodiment, the metal heat-conducting sleeve 22 is installed inside the connector 2, precisely corresponding to the position of the first heating ring 18. When the first heating ring 18 heats up, the metal heat-conducting sleeve 22 utilizes its excellent thermal conductivity to quickly transfer the heat generated by the first heating ring 18 to the connection part. The metal heat-conducting sleeve 22 can quickly conduct heat, causing the connection part between the positioning ring 16 and the connector 2 to heat up rapidly, improving the heat fusion efficiency. At the same time, it conducts heat evenly, avoiding excessive local temperature differences and ensuring the stability of the connection quality.

[0047] The working principle of this utility model is as follows:

[0048] During actual installation, the connector 2 is first fitted onto both ends of the pipe body 1, aligning the positioning ring 16 on the pipe body 1 with the positioning ring groove 17 inside the connector 2 and inserting it to complete the initial positioning. At this time, the positioning ring 16 and the first heating ring 18 inside the positioning ring groove 17 are directly opposite each other, the outer wall ring 3 on the pipe body 1 abuts against the connector 2, and the second heating ring 20 inside the outer wall ring 3 is also in a ready-to-work state.

[0049] When heat fusion is required, an external electromagnetic induction device is used to apply electromagnetic induction to the heat fusion ring 10 inside the connector 2, the first heating ring 18 inside the positioning ring groove 17, and the second heating ring 20 inside the outer wall ring 3, so that they generate heat.

[0050] The hot-melt ring 10 is made of electromagnetic induction heating material, which heats up rapidly after being energized. The first wall surface hot-melt holes 12 and the second wall surface hot-melt holes 13 inside the hot-melt ring 10 are staggered. This increases the contact area between the hot-melt material and the pipe body 1, improving the hot-melt effect. Furthermore, the different hole diameters ensure a more uniform heat distribution, preventing localized overheating or undercooling and thus guaranteeing stable welding quality. The ring anti-over-displacement block 15 prevents excessive displacement of the hot-melt ring 10 within the hot-melt cavity 9, ensuring that the hot-melt ring 10 is always in the correct working position.

[0051] The first heating ring 18 heats up under electromagnetic induction, further heat-melting and fixing the connection between the positioning ring 16 and the connector 2, enhancing the connection's strength. The perforated hole 19 in the first ring body reduces the weight of the first heating ring 18 while maintaining heating effectiveness, thus lowering costs.

[0052] The second heating ring 20 inside the outer ring 3 generates heat and assists in the connection between the connector 2 and the pipe body 1. The hollow hole 21 in the second ring also optimizes heat distribution and reduces weight.

[0053] The metal heat-conducting sleeve 22 is positioned corresponding to the first heating ring 18. The metal heat-conducting sleeve 22 has good thermal conductivity, which can quickly transfer the heat generated by the first heating ring 18 to the connection part, improve the heat melting efficiency, and make the heat distribution more uniform, thereby further ensuring the connection quality.
