[0002] In the current process of laying communication lines, in order to protect the communication cables, communication conduits are usually installed along the cable distribution path, and then the communication cables are installed inside the communication conduits. The communication conduits are used to protect the communication cables. When laying communication conduits, connectors are needed to connect adjacent communication conduits.

[0003] Existing pipe fittings are inadequate in terms of quick connection, the connection operation is relatively cumbersome, and they are also insufficient in adjusting the thermal expansion and contraction of the entire pipeline, so their practicality needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a quick-connect pipe fitting device that enables rapid assembly and disassembly without the need for tools. It also effectively eliminates stress caused by thermal expansion and contraction throughout the pipeline, making it highly practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A quick-connect pipe device includes a quick-connect body, which comprises a corrugated pipe section and two connecting pipe sections. The two connecting pipe sections are integrally connected to both ends of the corrugated pipe section. A rubber gasket is installed inside the quick-connect body. A wedge groove is provided at each end of the quick-connect body, and a wedge pipe is installed inside the wedge groove.

[0007] By adopting the above technical solution, convenient connection and fixation can be achieved, while effectively eliminating the stress caused by the thermal expansion and contraction of the entire pipeline.

[0008] Furthermore, a locking tube is installed inside the internal thread of the connecting pipe section, and the wedge-shaped tube is sleeved inside the locking tube.

[0009] By adopting the above technical solution, the locking tube can be used to drive the wedge tube to move axially.

[0010] Furthermore, a tapered through hole is provided at the central axis position of the wedge tube.

[0011] By adopting the above technical solution, it is ensured that the wedge tube can effectively compress the rubber pad.

[0012] Furthermore, one end of the locking tube is integrally connected to a second twisting end, and a through hole is provided at the central axis position of the second twisting end, and a communication tube is installed through the inside of the through hole, and the communication tube is inserted into the through hole at the central axis position of the rubber pad.

[0013] By adopting the above technical solution, it is easy to twist the locking tube.

[0014] Furthermore, one end of the connecting pipe section is integrally connected to a first twisting end.

[0015] By adopting the above technical solution, it is easy to hold the connecting pipe section.

[0016] Furthermore, the middle position of the outer surface of the rubber pad is adapted to the shape of the corrugated pipe section and is engaged in the arc groove of the corrugated pipe section.

[0017] By adopting the above technical solution, the positional stability of the rubber pad is ensured.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model allows for the connection of two communication pipes by first installing the wedge-shaped tube inside the locking tube, then fitting the locking tube and the wedge-shaped tube onto the outside of the communication pipe, inserting one end of the communication pipe into the inside of the rubber pad, and then twisting the second twisting end to thread the locking tube onto the connecting pipe section. This causes the locking tube to move axially, and the moving locking tube drives the wedge-shaped tube to move axially. At this time, the wedge-shaped tube can squeeze the rubber pad, thereby gradually locking the communication pipe. The entire connector device can quickly connect two communication pipes without the need for external tools, making it fast, convenient, and highly practical.

[0020] 2. This utility model, by setting a corrugated pipe section in the middle position of the quick connector body, can make the structure have a highly efficient self-adjusting structure and function for thermal expansion and contraction, which plays a positive role in maintaining the stable connection of the entire communication pipeline and is highly practical.

[0024] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 , Figure 2 The quick-connect fitting device for pipes includes a quick-connect fitting body 1, which comprises a corrugated pipe section 2 and two connecting pipe sections 3. The two connecting pipe sections 3 are integrally connected to both ends of the corrugated pipe section 2. A rubber gasket 10 is installed inside the quick-connect fitting body 1. A wedge groove 7 is provided at each end of the quick-connect fitting body 1. A wedge tube 9 is installed inside the wedge groove 7. A locking tube 8 is threaded inside the connecting pipe section 3. The wedge tube 9 is sleeved inside the locking tube 8. A tapered through hole is provided at the central axis of the wedge tube 9. The middle position of the outer surface of the rubber gasket 10 is adapted to the shape of the corrugated pipe section 2 and is engaged in the arc groove of the corrugated pipe section 2. A second twisting end 6 is integrally connected to one end of the locking tube 8, and a first twisting end 4 is integrally connected to one end of the connecting pipe section 3. When connecting the pipes, the wedge tube 9 can be first engaged inside the locking tube 8. The locking tube 8 and the wedge tube 9 are then fitted onto the outside of the communication pipe 5. One end of the communication pipe 5 is then inserted into the rubber pad 10. Next, the second twisting end 6 is twisted to thread the locking tube 8 onto the connecting pipe section 3, causing the locking tube 8 to move axially. The moving locking tube 8 drives the wedge tube 9 to move axially, thus squeezing the rubber pad 10 and gradually locking the communication pipe 5. The entire connector device can quickly connect two communication pipes 5 without the need for external tools, making it fast, convenient, and highly practical. The corrugated pipe section 2, located in the middle of the quick connector body 1, provides a highly efficient self-adjusting structure for thermal expansion and contraction, playing a positive role in maintaining the stable connection of the entire communication pipeline and demonstrating strong practicality.

[0026] Reference Figure 1 , Figure 2 A through hole is provided at the central axis position of the second twisting end 6, and a communication tube 5 is installed through the through hole. The communication tube 5 is inserted into the through hole at the central axis position of the rubber pad 10. The stability of rotating the locking tube 8 can be improved by using the first twisting end 4 and the second twisting end 6, ensuring that quick disassembly and assembly can be carried out conveniently.

[0027] Working principle: In use, firstly, the wedge tube 9 is installed inside the locking tube 8. Then, the locking tube 8 and the wedge tube 9 are sleeved on the outside of the communication pipe 5. Next, one end of the communication pipe 5 is inserted into the rubber pad 10. Then, the second twisting end 6 is twisted to make the locking tube 8 threadedly connected to the connecting pipe section 3, thereby making the locking tube 8 move axially. The moving locking tube 8 drives the wedge tube 9 to move axially. At this time, the wedge tube 9 can squeeze the rubber pad 10, thereby gradually locking the communication pipe 5. The entire connector device can quickly connect two communication pipes 5. At the same time, no external tools are needed during the entire connection process. It is fast, convenient and highly practical. By setting the corrugated pipe section 2 in the middle position of the quick connector body 1, the corrugated pipe section 2 can be used to make the structure have a highly efficient thermal expansion and contraction self-adjustment structure and function, which plays a positive role in maintaining the stable connection of the entire communication pipeline.
