Description

Technical Field

[0001] This utility model relates to the technical field of pipelines, and in particular to a pipeline structure that prevents the sealing ring from detaching. Background Technology

[0002] In piping systems, sealing rings are crucial components for ensuring the sealing performance of pipe connections. Traditional pipe sealing structures typically use sealing rings made of a single material, achieving a seal through direct compression or embedding in an installation groove. However, this design has significant drawbacks in practical applications: when pipes are connected, the sealing ring can easily be dislodged from the installation groove due to movement or vibration of the external pipe, leading to seal failure. Since the problem of the sealing ring detaching from the installation groove is usually difficult to detect visually, leaks are often only detected during subsequent water tightness tests. At this point, construction workers have to disassemble and reinstall the pipes, increasing workload and severely impacting construction progress and efficiency. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is: a pipe structure for preventing the sealing ring from detaching, including a pipe body, a clamp, a sealing ring and a ring spring. The pipe body is provided with an integrally connected main body part and an outer diameter part, and a stepped surface for limiting the position is formed between the main body part and the outer diameter part. The outer diameter part is provided with an installation groove for accommodating the sealing ring. The clamp is installed in the installation groove of the pipe body. The outer ring of the sealing ring is embedded with a ring spring, and the sealing ring is installed in the installation groove by the ring spring.

[0004] Using the above technical solution, the inner diameter of the outer diameter section of the pipe body is larger than the inner diameter of the main body, so that a stepped surface is naturally formed at the connection between the main body and the outer diameter section. This is used to limit the insertion depth of other pipes. A sealing ring is injection molded on the basis of a ring spring. The ring spring firmly fixes the sealing ring in the installation groove. When the pipe body is connected to an external pipe, it effectively prevents the sealing ring from falling off due to pipe movement. When the outer diameter section is clamped to other pipes, the sealing ring generates an outward force due to compression. Over time, this can easily cause the pipe body to deform. The inward clamping compensation through the clamp makes the pipe body structure more stable and prevents leakage at the connection of the pipe body.

[0005] The present invention is further configured such that the inner and outer rings of the sealing ring are divided into a sealing area and a hard area by a ring spring, the outer diameter portion forms a virtual cylinder for connecting to an external pipe, the hard area is located on the outside of the virtual cylinder, and the sealing area extends to the inside of the virtual cylinder.

[0006] With the above technical solution, the rigid area is located in the mounting groove, the annular spring provides rigid support for the installation of the sealing ring, the sealing ring is fixed in the mounting groove, and interference between the annular spring and the external pipe is avoided. The sealing ring is used to deform and fill the gap of the pipe with sufficient margin to maintain the stability of the sealing structure.

[0007] The present invention is further provided that the outer side of the sealing ring is provided with an opening groove.

[0008] By adopting the above technical solution, an opening groove is naturally formed during the injection molding of the sealing ring to fix the annular spring, and the opening groove can alleviate the problem of stress concentration when the sealing ring is deformed.

[0009] The present invention is further configured such that the outer side of the outer diameter portion is provided with a slot, and the slot is distributed on both sides of the mounting groove, and the clamp is installed on the pipe body through the mounting groove.

[0010] Furthermore, the clamp includes an upper clamp band and a lower clamp band that are hinged together, a screw that is rotatably connected to the lower clamp band, and a locking screw sleeve for locking the upper clamp band and the lower clamp band. The inner sides of the upper clamp band and the lower clamp band are provided with protrusions that abut against the clamping groove.

[0011] Using the above technical solution, one end of the upper and lower clamps is hinged, and the other end is fixed by a screw thread. The protrusions of the upper and lower clamps are designed to effectively avoid the installation groove of the pipe body, so that the clamps are evenly stressed and the stability of the overall structure is enhanced.

[0020] like Figure 1-3 As shown, this utility model provides a pipe structure to prevent the sealing ring from detaching, including a pipe body 1, a clamp 2, a sealing ring 3, and a ring spring 4. The pipe body 1 has an integrally connected main body part 5 and an outer diameter part 6. A stepped surface 7 for limiting the position is formed between the main body part 5 and the outer diameter part 6. The outer diameter part 6 has an installation groove 8 for accommodating the sealing ring 3. The clamp 2 is installed in the installation groove 8 of the pipe body 1. The ring spring 4 is embedded in the outer ring of the sealing ring 3. The sealing ring 3 is installed in the installation groove 8 by the ring spring 4.

[0021] In this invention, since the inner diameter of the outer diameter portion 6 of the pipe body 1 is larger than the inner diameter of the main body portion 5, a stepped surface 7 is naturally formed at the connection between the main body portion 5 and the outer diameter portion 6. This is used to limit the insertion depth of other pipes. A sealing ring 3 is injection molded on the basis of the annular spring 4. The sealing ring 3 is firmly fixed in the mounting groove 8 by the annular spring 4. When the pipe body 1 is connected to an external pipe, the sealing ring 3 is effectively prevented from falling off due to pipe movement. When the outer diameter portion 6 is clamped to other pipes, the sealing ring 3 generates an outward force due to compression. Over time, this can easily cause the pipe body 1 to deform. The inward clamping compensation by the clamp 2 makes the structure of the pipe body 1 more stable and prevents leakage at the connection of the pipe body 1.

[0022] Combination Figure 4 , 5 As shown, in this embodiment, the inner and outer rings of the sealing ring 3 are divided into a sealing area 9 and a hard area 10 by the annular spring 4. The outer diameter portion 6 forms a virtual cylinder 11 for connecting to an external pipe. The hard area 10 is located on the outside of the virtual cylinder 11, and the sealing area 9 extends to the inside of the virtual cylinder 11. The hard area 10 is located in the mounting groove 8. The annular spring 4 provides rigid support for the installation of the sealing ring 3. The sealing ring 3 is fixed in the mounting groove 8, and interference between the annular spring 4 and the external pipe is avoided. The sealing ring 3 is used to deform and fill the gap of the pipe with sufficient margin to maintain the stability of the sealing structure.

[0023] In this embodiment, the outer side of the sealing ring 3 is provided with an opening groove 12. When the sealing ring 3 is injection molded, the opening groove 12 is naturally formed to fix the annular spring 4, and the opening groove 12 can alleviate the problem of stress concentration when the sealing ring 3 is deformed.

[0024] Combination Figure 6As shown, in this embodiment, the outer side of the outer diameter portion 6 is provided with a groove 13, and the groove 13 is distributed on both sides of the mounting groove 8. The clamp 2 is installed on the pipe body 1 through the mounting groove 8. The clamp 2 includes an upper clamp band 14 and a lower clamp band 15 that are hinged together, a screw 16 that is rotatably connected to the lower clamp band 15, and a locking nut 17 for locking the upper clamp band 14 and the lower clamp band 15. The inner side of the upper clamp band 14 and the lower clamp band 15 is provided with a protrusion 18 that abuts against the groove 13. One end of the upper clamp band 14 and the lower clamp band 15 is hinged, and the other end is threadedly fixed by the screw 16 and the locking nut 17. The protrusion 18 of the upper clamp band 14 and the lower clamp band 15 is designed to effectively avoid the mounting groove 8 of the pipe body 1, so that the clamp 2 is evenly stressed and the stability of the overall structure is enhanced.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
