Description

Technical Field

[0001] This utility model relates to the field of plumbing technology, specifically to a leak-proof plumbing sealing joint. Background Technology

[0002] Plumbing systems are closed systems specifically designed to transport hot or cold water to provide heating, domestic hot water, or cooling. They are a core infrastructure for heating and domestic hot water supply in modern buildings. Their materials must balance thermal conductivity, temperature resistance, and corrosion resistance.

[0003] In current plumbing construction, hot-melt butt welding is the mainstream connection method, but this process requires high operational precision. If the hot-melt temperature is not properly controlled during construction, the heating time is insufficient, or there is misalignment during the connection, fine gaps that are difficult to see with the naked eye can easily form at the pipe joints. Under long-term water pressure, these hidden gaps will gradually lead to water seepage problems, not only affecting normal water use, but also potentially seeping into the walls or floors, causing subsequent troubles such as damage to decorations and disputes with neighbors.

[0004] Meanwhile, plumbing pipes often face special requirements during actual installation. For example, in ceilings, floor slabs, or wall penetrations, additional support and fixation are needed to prevent pipe displacement due to their own weight or external vibrations. Protective measures are also required to resist external friction, compression, or environmental corrosion. However, existing piping systems mostly focus only on the transportation function and lack integrated support and protection designs, making it difficult to meet the stability and durability requirements in complex installation environments. Utility Model Content

[0005] To solve the above-mentioned problems, this utility model proposes a leak-proof water pipe sealing joint with an auxiliary docking structure at the joint to improve sealing performance and a built-in protective support structure on the pipe.

[0006] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a leak-proof sealing joint for plumbing pipes, comprising:

[0007] The tube body has hot melt adhesive storage ring cavities fixed on the inner sides of both ends, and an adhesive filling port fixed on the top, which communicates with the hot melt adhesive storage ring cavities. The adhesive filling port can be sealed, and several adhesive grooves are provided on the inner wall end of the tube body.

[0008] The protective sleeve is tightly wrapped and fixed to the outside of the tube body;

[0009] The support frame is symmetrically arranged on the upper and lower sides of the protective sleeve and is detachable. The bottom surface is equipped with anti-slip rubber strips.

[0010] Furthermore, the hot melt adhesive storage ring cavity is provided in two parts.

[0011] Furthermore, the threaded connection on the glue inlet is equipped with a sealing cap.

[0012] Furthermore, the glue grooves are distributed in a ring-shaped, equidistant pattern along the inner wall of the tube.

[0013] Furthermore, the protective sleeve is located in the middle of the pipe body, and the support frame is located in the middle of the protective sleeve.

[0014] Furthermore, the support frame is U-shaped, with symmetrically integrally formed locking blocks on its inner sidewall, and the outer wall of the protective sleeve is provided with slots for the locking blocks to be tightly inserted. The two support frames are arranged opposite each other, and their ends on the same side can contact each other.

[0015] Compared with the prior art, the advantages of this utility model are as follows: both ends of the joint are equipped with a hot-melt adhesive storage structure, which can simultaneously provide sealant from both sides, forming a double sealing redundancy, which can flexibly deal with the risk of leakage in different locations and avoid water leakage caused by the failure of a single seal; the annular adhesive grooves at the inner wall end are evenly distributed, allowing the hot-melt sealant to fill evenly, forming multiple tight sealing defenses, which not only ensures the uniformity of the seal but also further improves the reliability of the seal; the glue filling port is equipped with a sealable threaded cap, which not only prevents the sealant from overflowing and affecting the sealing effect but also facilitates the subsequent replenishment of sealant, ensuring long-term stable sealing performance.

[0016] The outer protective sleeve can specifically wrap around the core area of ​​the connector, effectively dispersing the impact of external forces on the pipe body and reducing damage caused by collisions or squeezing; the detachable support frames on the upper and lower sides can be quickly installed and removed through a snap-fit ​​structure, and the symmetrically arranged support frames can be contacted on the same side, which greatly enhances the overall support strength. Combined with the anti-slip rubber strip on the bottom, it can keep the connector stable during use and extend its service life. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 AppendixFigure 4 A leak-proof sealing joint for plumbing pipes includes: a pipe body 1, with hot-melt adhesive storage ring cavities 2 fixedly provided on the inner sides of both ends. There are two hot-melt adhesive storage ring cavities 2, which can provide sealant from both ends of the joint to enhance sealing redundancy, improve leak-proof effect, and cope with the risk of leakage that may occur in different locations.

[0024] Combined with appendix Figure 1 Appendix Figure 3 The tube body 1 is fixedly provided with a glue inlet 3 that communicates with the hot melt glue storage ring cavity 2. The glue inlet 3 can be sealed. A sealing cap 8 is threadedly connected to the glue inlet 3, which can reliably seal the glue inlet, prevent the sealant from overflowing, and facilitate subsequent replenishment of sealant, making the operation convenient.

[0025] Combined with appendix Figure 1 Appendix Figure 4 The inner wall end of the tube body 1 is provided with several glue grooves 4. The glue grooves 4 are distributed in a ring shape at equal intervals along the inner wall of the tube body 1, which can make the hot-melted sealant fill evenly, forming multiple sealing defenses and improving the uniformity and reliability of the seal.

[0026] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 4 A protective sleeve 5 is tightly wrapped and fixed to the outside of the pipe body 1; a support frame 6 is symmetrically arranged on the upper and lower sides of the protective sleeve 5 and is detachable, with an anti-slip rubber strip 7 on the bottom surface. The protective sleeve 5 is located in the middle of the pipe body 1, and the support frame 6 is located in the middle of the protective sleeve 5, which can specifically protect the core area of ​​the joint, disperse the impact of external forces on the pipe body 1, increase the stability of the sealing joint, and extend the service life. The support frame 6 is U-shaped, with symmetrically integrally formed locking blocks 9 on its inner side wall, and slots 10 on the outer wall of the protective sleeve 5 for the locking blocks 9 to be tightly inserted, which can realize quick disassembly and installation. The two support frames 6 are arranged opposite each other, and the ends on the same side can contact each other, which can enhance the overall support strength.

[0027] The specific implementation method of this utility model is as follows: After the ends of the plumbing pipes to be connected are heat-fused, they are inserted into both ends of the pipe body 1, ensuring a tight connection between the pipe and the pipe body 1. The sealing cap 8 on the glue inlet 3 is unscrewed, and sufficient sealant is injected into the heat-melt storage ring cavity 2 inside both ends of the pipe body 1 through the glue inlet 3. After injection, the sealing cap 8 is tightened to prevent overflow. The heat-melt storage ring cavity 2 automatically heats-melts upon contact with the heat-melt end of the plumbing pipe, causing the sealant inside to melt and flow into the connection between the plumbing pipe and the pipe body 1, entering the glue groove 4. Because the glue groove 4 is distributed in a ring-shaped, equidistant pattern along the inner wall of the pipe body 1, the sealant will evenly fill and form multiple sealing layers. After the sealant cools and solidifies, a sealed connection is achieved. Install two U-shaped support brackets 6 on the upper and lower sides of the protective sleeve 5, and insert the locking block 9 on the inner wall of the support bracket 6 into the slot 10 on the outer wall of the protective sleeve 5 to complete the installation of the support bracket 6. At this time, the two support brackets 6 are set opposite each other and their ends are in contact. With the help of the anti-slip rubber strip 7 on the bottom, they can stably support and protect the joint. The entire installation and use process is then complete.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
