Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a leak-proof structure for drainage pipe construction. Background Technology

[0002] Drainage pipelines refer to the systems of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. They include main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are built on streets or anywhere else, any pipe that serves a drainage function can be called a drainage pipeline.

[0003] However, during the construction of existing drainage pipes, a sealing ring is usually fitted at the connection between two drainage pipes and fixed between the two drainage pipes with a clamp to solve the leakage problem. However, the sealing range of the sealing ring is related to the production specifications and it is difficult to adapt to the connection of drainage pipes of different sizes, making it difficult to completely cover and seal the gap at the connection of the two drainage pipes. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a leak-proof structure for drainage pipe construction. This solves the problem that in existing drainage pipe construction, a sealing ring is usually fitted at the connection between two drainage pipes and fixed between the two drainage pipes with a clamp to solve the leakage problem. However, the sealing range of the sealing ring is related to the production specifications and it is difficult to adapt to the connection of drainage pipes of different sizes, thus making it difficult to completely cover and seal the gap at the connection of the two drainage pipes.

[0005] To achieve the above-mentioned technical objectives, the present invention provides a leak-proof structure for drainage pipe construction, including a connecting pipe. The connecting pipe is hollow inside and open at both ends. The connecting ends of two drainage pipes are respectively inserted into the connecting pipe from both ends and are detachably connected to the connecting pipe through fixing components. A limiting ring is provided in the middle of the inner wall of the connecting pipe. A sealing ring is provided between the limiting ring and the connecting ends of the two drainage pipes to seal the connection between the limiting ring and the connecting ends of the two drainage pipes, thereby sealing the connection between the two drainage pipes.

[0006] Furthermore, the fixing component includes bolts, and the side wall of the connecting pipe has threaded holes, with the bolts threaded into the inside of the threaded holes.

[0007] Furthermore, the fixing assembly also includes a fixing ring installed on the outer wall of the pipe connection end, and the outer wall of the fixing ring is provided with an annular groove.

[0008] Furthermore, the cross-section of the annular groove is a right-angled triangular structure.

[0009] Furthermore, the bolt's threaded end is equipped with a retaining ball.

[0010] Furthermore, the fixing ring is movably fitted onto the drainage pipe, and the outer wall of the connection end of the drainage pipe is provided with a retaining ring to block the fixing ring.

[0011] Furthermore, the retaining ring and the drainage pipe are integrally molded.

[0012] Furthermore, the limiting ring and the connecting pipe are integrally formed.

[0013] Furthermore, the sealing ring is either a silicone ring or a rubber ring.

[0014] The beneficial effects of this utility model include:

[0015] 1. When sealing the connection between two drainage pipes, insert the connection ends of the two drainage pipes into the connection pipe from both ends. At the same time, the sealing ring can seal the connection between the limiting ring and the connection ends of the two drainage pipes, thus sealing the connection between the two drainage pipes. This avoids the problem that existing drainage pipe sealing methods cannot completely cover and seal the gaps at the connection between the two drainage pipes, resulting in a good sealing effect.

[0016] 2. The fixing component includes a bolt, and the side wall of the connecting pipe has a threaded hole. The bolt is threaded into the threaded hole, and the bolt's screw end has a fixing ball. The fixing component also includes a fixing ring installed on the outer wall of the drain pipe connection end. The outer wall of the fixing ring has an annular groove with a right-angled triangular cross-section. When the connecting pipe is connected to the drain pipe connection end, the bolt can drive the fixing ball to move inside the annular groove on the outer wall of the fixing ring, so that the drain pipe and the connecting pipe move relative to each other. This makes the connection between the drain pipe connection end and the limiting ring and sealing ring tighter, thereby further improving the sealing effect. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] This utility model embodiment provides a leak-proof structure for drainage pipe construction, such as... Figure 1-3 As shown, it includes a connecting pipe 1, which is hollow inside and open at both ends. The connecting ends of two drainage pipes 2 are inserted into the connecting pipe 1 from both ends and are detachably connected to the connecting pipe 1 by fixing components 3. A limiting ring 11 is provided in the middle of the inner wall of the connecting pipe 1. The limiting ring 11 is integrally formed with the connecting pipe 1. A sealing ring 4 is provided between the limiting ring 11 and the connecting ends of the two drainage pipes 2. The sealing ring 4 is either a silicone ring or a rubber ring to seal the connection between the two drainage pipes 3. This avoids the problem that the existing drainage pipe sealing method is difficult to completely cover and seal the gap at the connection of the two drainage pipes 2, and the sealing effect is good.

[0023] In this embodiment, the fixing component 3 includes a bolt 31. The side wall of the connecting pipe 1 is provided with a threaded hole 12. The bolt 31 is threaded into the threaded hole 12. The bolt 31 has a fixing ball 33 at the screw end. The fixing component 3 also includes a fixing ring 32 installed on the outer wall of the connecting end of the drain pipe 2. The outer wall of the fixing ring 32 is provided with an annular groove 321. By adjusting the bolt 31, the fixing ball 33 can be fixed inside the annular groove 321 or loosened from the annular groove 321, so that the connecting pipe 1 and the two drain pipes 2 can be detachably connected. At the same time, the cross section of the annular groove 321 is a right-angled triangular structure. When the connecting end of the connecting pipe 1 and the drain pipe 2 is connected, the bolt 31 can drive the fixing ball 33 to move inside the annular groove 321 on the outer wall of the fixing ring 32, so that the drain pipe 2 and the connecting pipe 1 move relative to each other. This makes the connection between the connecting end of the drain pipe 2 and the limiting ring 11 and the sealing ring 4 tighter, thereby further improving the sealing effect.

[0024] In this embodiment, the fixing ring 32 is movably sleeved on the drainage pipe 2. The outer wall of the connecting end of the drainage pipe 2 is provided with a retaining ring 21 for blocking the fixing ring 32. The retaining ring 21 is integrally formed with the drainage pipe 2. The retaining ring 21 can not only restrict the fixing ring 32 on the drainage pipe 2, but also increase the contact area between the connecting end of the drainage pipe 2 and the sealing ring 4, thereby improving the sealing effect.

[0025] Specific principle: When sealing the connection between the connecting pipe 1 and the drain pipe 2, the connecting ends of the two drain pipes 2 are inserted into the connecting pipe 1 from both ends. After the two drain pipes 2 are inserted into the connecting pipe 1, the adjusting bolt 31 is adjusted. The bolt 31 can drive the fixing ball 33 to move inside the annular groove 321 on the outer wall of the fixing ring 32, so that the drain pipe 2 and the connecting pipe 1 move relative to each other. This allows the connecting end of the drain pipe 2 and the limiting ring 11 to be sealed together by the sealing ring 4. This seals the connection between the two drain pipes 2, avoiding the problem that the existing sealing method of the drain pipe 2 is difficult to completely cover and seal the gap at the connection of the two drain pipes 2. The sealing effect is good.

[0026] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
