[0015] Compared with the prior art, the beneficial effects of this utility model are: the PVC pipe with snap-fit structure not only achieves quick connection and improves the strength of the pipe fitting, but also improves the sealing performance after connection;
[0016] (1) By setting up a connecting sleeve, threaded collar, connecting block, groove, connecting spring, connecting slot and positioning ring, when connecting, one side of the PVC pipe body of one set of pipe fittings is inserted into the connecting sleeve of another set of pipe fittings. After being inserted into place, the connecting spring quickly rebounds and pushes out the connecting block, so that the connecting block is inserted into the connecting slot and engages with it. Thus, the two sets of pipe fittings are connected by the connecting spring. Then, the threaded collar is rotated to cooperate with the thread on the outside of the connecting sleeve to move it to one side outside the connecting sleeve, thereby pressing the connecting spring to prevent it from deforming and affecting the connection firmness. This enables the rapid connection of multiple sets of pipe fittings.

After the two sets of pipe fittings are connected, the sealing ring and sealing ring fit tightly to ensure the sealing performance. The fixing ring inside the connecting sleeve can support the sealing ring to prevent it from deforming and affecting the sealing effect. Similarly, the positioning ring on one side of the PVC pipe body can position and support the sealing ring through the annular groove to prevent it from shifting and deforming, thus effectively improving the sealing performance after connection.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example: Please refer to Figure 1-4 A PVC pipe with a snap-fit structure includes a PVC pipe body 1, a positioning ring 13 fixedly connected to one side of the PVC pipe body 1, the center line of the positioning ring 13 and the center line of the PVC pipe body 1 are on the same vertical plane, a connecting sleeve 4 fixedly connected to one side of the PVC pipe body 1, the center line of the connecting sleeve 4 and the center line of the PVC pipe body 1 are on the same horizontal plane, and a snap-fit structure for quick connection is provided inside the connecting sleeve 4.
[0026] The snap-fit structure includes a connecting slot 11. A connecting slot 11 is provided on one side of the outer side of the PVC pipe body 1. Four sets of grooves 7 are provided on one side of the connecting sleeve 4. A connecting spring 8 is fixedly connected to one side inside the groove 7. A connecting block 6 is fixedly connected to one side of one end of the connecting spring 8. A threaded collar 5 is movably connected to the outside of the connecting sleeve 4.
[0027] The threaded collar 5 is movably connected to the connecting spring 8, and the connecting block 6 is movably connected to the connecting groove 11;
[0028] The grooves 7 on one side of the connecting sleeve 4 are arranged at equal intervals, and the center line of the connecting slot 11 is on the same horizontal plane as the center line of the PVC pipe body 1.
[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during connection, one side of the PVC pipe body 1 of one set of pipe fittings is inserted into the connecting sleeve 4 of another set of pipe fittings. After insertion, the connecting spring 8 rebounds quickly and pushes out the connecting clip 6, so that the connecting clip 6 is inserted into the connecting slot 11 and engages with it. Thus, the two sets of pipe fittings are connected by the connecting spring 8. Then, the threaded collar 5 is rotated to cooperate with the thread on the outside of the connecting sleeve 4 and move it to the outside of the connecting sleeve 4, thereby pressing the connecting spring 8 to prevent its deformation from affecting the connection firmness. This allows for the rapid connection of multiple sets of pipe fittings.
[0030] The PVC pipe body 1 has a protruding strip 2 for external fixed connection, a reinforcing ring 3 for external fixed connection, and a reinforcing rib 10 for internal fixed connection of the reinforcing ring 3.
[0031] The positioning ring 13 is fixedly connected to the protrusion 2, and the protrusion 2 is fixedly connected to the reinforcing ring 3;
[0032] Specifically, such as Figure 1 and Figure 3 As shown, multiple sets of protruding strips 2 and reinforcing rings 3 are fixed at equal intervals on the outside of the PVC pipe body 1. The protruding strips 2 and reinforcing rings 3 are connected to each other and can support each other, thus improving the strength of the PVC pipe body 1. Reinforcing ribs 10 are fixed inside the reinforcing rings 3. The reinforcing ribs 10 can further improve the strength of the PVC pipe body 1 and reduce the probability of sharp objects piercing the PVC pipe body 1, thereby effectively improving the strength of the PVC pipe.
[0033] A sealing ring 9 is movably connected to one side inside the connecting sleeve 4, a fixing ring 14 is fixedly connected to one side inside the connecting sleeve 4, a sealing ring 12 is movably connected to one side of the PVC pipe body 1, an annular groove 16 is opened on one side of the sealing ring 12, and a positioning ring 15 is fixedly connected to one side of the PVC pipe body 1.
[0034] The positioning ring 15 is movably connected to the annular groove 16, and the center line of the sealing ring 12 is on the same vertical plane as the center line of the PVC pipe body 1.
[0035] The sealing ring 9 is movably connected to the fixed ring 14, and the center line of the sealing ring 9 is on the same horizontal plane as the center line of the sealing ring 12.
[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, after the PVC pipe is connected, the sealing ring 12 on one side of the PVC pipe body 1 is inserted into the interior of the connecting sleeve 4 and fits against the sealing ring 9 inside the connecting sleeve 4. After the two sets of pipe fittings are connected, the sealing ring 9 and the sealing ring 12 fit tightly to ensure the sealing performance. The fixing ring 14 inside the connecting sleeve 4 can support the sealing ring 9 to prevent it from deforming and affecting the sealing effect. Similarly, the positioning ring 15 on one side of the PVC pipe body 1 can position and support the sealing ring 12 through the annular groove 16 to prevent it from shifting and deforming, thus effectively improving the sealing performance after connection.
[0037] Working Principle: In use, when connecting, one side of the PVC pipe body 1 of one set of fittings is inserted into the connecting sleeve 4 of another set of fittings. After insertion, the connecting spring 8 quickly rebounds, pushing out the connecting clip 6, causing it to engage with the connecting slot 11. This connects the two sets of fittings via the connecting spring 8. Then, the threaded collar 5 is rotated to engage with the threads on the outside of the connecting sleeve 4, moving it to the outside of the connecting sleeve 4. This presses the connecting spring 8 to prevent deformation and ensure a secure connection. After connection, the sealing ring 12 on one side of the PVC pipe body 1 is inserted into the connecting sleeve 4 and fits against the sealing ring 9 inside the connecting sleeve 4, thus connecting the two sets of fittings. The tight fit between the sealing ring 9 and the sealing ring 12 ensures a tight seal. The fixing ring 14 inside the connecting sleeve 4 supports the sealing ring 9 to prevent deformation and maintain the sealing effect. Similarly, the positioning ring 15 on one side of the PVC pipe body 1 can position and support the sealing ring 12 through the annular groove 16 to prevent it from shifting or deforming. Multiple sets of protruding strips 2 and reinforcing rings 3 are fixed at equal intervals on the outside of the PVC pipe body 1. The protruding strips 2 and reinforcing rings 3 are connected to each other to support each other and improve the strength of the PVC pipe body 1. The reinforcing rings 3 have reinforcing ribs 10 fixed inside, which can further improve the strength of the PVC pipe body 1 and reduce the probability of sharp objects piercing the PVC pipe body 1.
