Description

Technical Field

[0001] This utility model relates to the field of PPR pipes, and in particular to a PPR pipe structure with integrated internal and external threads at the ends. Background Technology

[0002] PPR pipes play a vital role in modern building water supply and drainage systems. Widely used in hot and cold water supply systems within buildings, PPR pipes are suitable for long-term domestic water supply due to their excellent heat resistance and pressure resistance. Because of their superior insulation and high-temperature resistance, PPR pipes are also commonly used in underfloor heating systems and radiator connection pipes. PPR material itself is non-toxic and odorless, meeting drinking water hygiene standards and will not pollute water quality, ensuring the safety of residents' drinking water. PPR pipes have excellent anti-aging properties and a long service life, lasting over 50 years under normal conditions. They also possess good impact resistance and compressive strength, making them resistant to breakage or deformation. PPR pipes are typically connected using a heat fusion method, a simple and quick connection that forms a robust whole upon cooling, avoiding the leakage problems common in traditional metal pipes. Furthermore, the lightweight nature of PPR pipes facilitates handling and installation. PPR pipes have a low thermal conductivity and good insulation properties, effectively reducing heat loss, making them particularly suitable for hot water supply systems and contributing to energy conservation. In traditional PPR piping systems, connecting threaded metal valves or fittings requires the use of adapters, which involves cumbersome installation steps, multiple hot-melt welding processes, increased risk of leakage, complex connection structures, large space requirements, and is unsuitable for construction in confined spaces.

[0003] Chinese Patent CN222616315U discloses a snap-fit ​​structure for PPR pipes, which achieves quick connection of the first and second pipes by controlling the position of the second snap-fit ​​component through an adjusting ring. However, during pipe installation, there is a problem that it is inconvenient to adjust the pipe length according to the installation distance. In view of this, a PPR pipe structure with integrated internal and external threads at the end is provided. Utility Model Content

[0031] This embodiment provides a PPR pipe structure with integrated internal and external threads at the ends, including a connecting pipe 2, a pipe b21 extending through the side wall of the connecting pipe 2, a baffle 24 fixedly installed in the middle of the pipe b21, a rotating groove 241 extending through the side wall of the middle of the baffle 24, an installation plate 31 rotatably installed in the rotating groove 241, and a plurality of sliding grooves 23 formed on the arc wall of the pipe b21. It also includes an installation pipe 1, an installation groove 12 formed on one side wall of the installation pipe 1, one end of the connecting pipe 2 inserted into the installation groove 12, and a plurality of limiting blocks 121 symmetrically fixedly installed on the arc wall of the installation groove 12 near the groove opening. The limiting blocks 121 are slidably installed in the sliding grooves 23, and the length of the overall pipe is adjusted by the connecting pipe 2 sliding along the installation groove 12.

[0032] like Figure 1 , Figure 7 , Figure 8 As shown, a pipe a11 is provided through the side wall of the installation pipe 1. An external thread 112 is provided on the outer arc wall of the installation pipe 1 near one edge. An internal thread 111 is provided on the arc wall of the pipe a11 near one edge.

[0033] like Figure 4 , Figure 5As shown, the sliding groove 23 has several limiting grooves 231 on its side wall. The limiting grooves 231 are arc-shaped. The opening of the limiting groove 231 has an inward angle that slopes from the sliding groove 23 to the limiting groove 231. The limiting block 121 is rotated into the limiting groove 231 to fix the length of the entire pipe. The angle at the opening of the limiting groove 231 facilitates the rotation of the limiting block 121 into the limiting groove 231.

[0034] like Figure 5 As shown, a locking block 232 is fixedly installed on the side wall of the limiting groove 231. A downward angle is opened on one side of the locking block 232 from the sliding groove 23 into the limiting groove 231. The angle on one side of the locking block 232 facilitates the rotation of the limiting block 121 to the bottom of the limiting groove 231. The limiting block 121 can be rotated to the outside of the limiting groove 231 by forcefully rotating the connecting pipe 2.

[0035] like Figure 5 As shown, the card block 232 is made of a flexible material, wherein the card block 232 is preferably made of flexible rubber.

By forcefully rotating the connecting pipe 2, the limiting block 121 can be rotated outside the limiting groove 231. A baffle 24 is fixedly installed in the middle of the pipe b21. A rotating groove 241 is opened through the side wall of the baffle 24. An installation plate 31 is rotatably installed in the rotating groove 241. A shaft hole 242 communicating with the rotating groove 241 is opened on the outer arc wall of the connecting pipe 2. An installation shaft is rotatably installed in the shaft hole 242. 3. The mounting plate 31 is fixedly mounted on the mounting shaft 3. One end of the mounting shaft 3 is rotatably mounted inside the baffle 24, and the other end of the mounting shaft 3 is exposed to the outside.
