Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a socket-type quick-sealing interface structure for drainage pipes. Background Technology

[0002] In urban infrastructure construction, building drainage, and agricultural irrigation projects, drainage pipeline systems are indispensable infrastructure. These systems are typically composed of multiple standard-length pipe sections connected together, and the interfaces between these pipes are the weakest points in the entire system. Socket joints are widely used due to their simple structure and ease of installation. However, the sealing performance at the interface directly determines the operational safety of the entire pipeline system. Leakage not only wastes water resources but can also pollute the soil and groundwater, even eroding the foundation, leading to road collapse or structural damage to buildings. Therefore, improving the sealing reliability and ease of installation of socket joints has always been a key research focus in this field.

[0003] In existing technologies, the sealing of socket joints in drainage pipes primarily relies on a single elastic sealing ring. Specifically, a groove is typically created on the outer wall of the spigot, or a cavity is pre-formed on the inner wall of the socket, within which an O-ring or irregularly shaped sealing ring made of rubber or synthetic material is placed. When the spigot is inserted into the socket, the sealing ring undergoes elastic deformation under radial compression, filling the gap between the outer wall of the spigot and the inner wall of the socket, forming a sealing barrier through the resilience of the rubber. This technology is simple in principle, relatively low in cost, and can meet basic sealing requirements to a certain extent, thus it is widely used. Its sealing effect depends entirely on the compression of the single sealing ring and the long-term elasticity retention of the material.

[0004] However, the existing technology relying on a single elastic sealing ring has significant defects in sealing reliability. First, this single-point sealing structure lacks redundant protection. Once the sealing ring is twisted, displaced, or scratched during installation, the seal of the entire interface will immediately fail, and such internal defects are difficult to detect after installation. Second, the compressive force on the sealing ring in the circumferential direction may be uneven, easily forming local weak points in the seal. More importantly, during long-term use, the pipeline will expand and contract due to temperature changes, or experience displacement and angular deformation due to external factors such as uneven foundation settlement and vehicle vibration. These will repeatedly act on the single sealing ring, leading to elastic fatigue, permanent deformation, or even separation from the pipe wall, thus forming a leakage channel. Therefore, a socket-type quick-sealing interface structure for drainage pipelines is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a socket-type quick-sealing interface structure for drainage pipes, which aims to improve the existing technology that relies on a single elastic sealing ring. Its structure lacks redundant protection, is easily damaged during installation, and is prone to failure due to fatigue deformation during long-term use, resulting in poor sealing reliability and the risk of leakage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-sealing interface structure for a drainage pipe with a socket, comprising a pipe one and a pipe two, wherein a socket is provided at one end of the pipe one and a socket is provided at one end of the pipe two, the socket is inserted into the socket, a rubber sealing gasket and a support ring are sequentially provided at the connection between the socket and the socket, and a sealing component is provided outside the rubber sealing gasket. The sealing assembly includes a wedge one and a wedge two. One side of the wedge one is fixedly connected to one side of the outer wall of the rubber sealing gasket, and one side of the wedge two is fixedly connected to the other side of the outer wall of the rubber sealing gasket. Both the wedge one and the wedge two are inserted into the socket, and the rubber sealing gasket wraps around the end of the socket away from its port.

[0007] As a further description of the above technical solution: the rubber sealing gasket, together with the attached wedge one and wedge two, and their specific wrapping positions away from the socket port, cooperate with each other to wedge into the socket when the socket is inserted, thereby achieving physical filling and multi-point compression of the sealing gap, while protecting the sealing body from damage during installation, thus forming a reliable internal sealing effect.

[0008] Specifically, there are two wedges, which are arranged symmetrically along the top and bottom.

[0009] As a further description of the above technical solution: the second wedge is arranged in two symmetrical positions, forming a circumferential force balance with the first wedge, which realizes the generation of uniform radial extrusion force on the pipe interface during insertion, effectively avoiding local stress concentration, thereby achieving a stable sealing effect without weak points.

[0010] Specifically, the rubber sealing gasket, the first wedge, and the second wedge are integrally formed.

[0011] As a further description of the above technical solution: the structural cooperation between the support ring and the extension blocks at both ends, by inserting them into the two pipe sections, achieves an internal bridging support effect for the interface area, enhancing the overall integrity of the connection.

[0012] Specifically, both ends of the support ring are fixedly connected to extension blocks, one of which is inserted into the interior of pipe one and the other is inserted into the interior of pipe two.

[0013] As a further description of the above technical solution: the support ring, in combination with the properties of its rigid material, provides physical support to the pipe connection, thereby achieving a structural reinforcement effect that resists external stress and prevents interface breakage.

[0014] Specifically, the support ring is made of a rigid material and is used to provide rigid support at the connection between the first pipe and the second pipe to prevent breakage.

[0015] As a further description of the above technical solution: the support ring, the sealing ring, and the built-in protrusion one and protrusion two cooperate with each other to form a composite sealing structure outside the interface, thereby achieving the effect of a second layer of sealing protection.

[0016] Specifically, a sealing ring is fitted on the outer wall of the support ring, and a first protrusion and a second protrusion are provided inside the sealing ring.

[0017] As a further description of the above technical solution: the integral molding and symmetrical arrangement of the protrusions, and their tight fit with the socket and the inlet, respectively, achieve the effect of applying uniform local high pressure to the external sealing ring, thereby achieving the effect of locking and tightly sealing the external gap.

[0018] Specifically, the first protrusion and the second protrusion are integrally formed with the sealing ring and are arranged symmetrically from left to right.

[0019] As a further description of the above technical solution: the integrated molding structure of the protrusion and the sealing ring, along with their symmetrical layout, simplifies the manufacturing process and ensures precise component positioning. Simultaneously, the symmetrical design ensures that the sealing pressure applied by the protrusion to the socket and spigot is evenly distributed after assembly, avoiding the risk of localized seal failure due to uneven stress, thus achieving a stable and reliable external sealing effect.

[0020] Specifically, the extension block is located at the circumferential edge of the support ring and is integrally formed with the support ring.

[0021] As a further description of the above technical solution: the position of the extension block at the circumferential edge of the support ring and its integral molding structure with the support ring effectively extend the rigid support of the support ring to the inside of the pipes at both ends, achieving an excellent structural reinforcement effect.

[0022] This utility model has the following beneficial effects: 1. In this utility model, by setting an integrally molded rubber sealing gasket, wedge one and wedge two, a multi-wedge-type sealing structure is formed between the socket and the inlet; when the inlet is inserted, the wedges of different shapes can fully fill and press the gap to achieve a reliable internal seal; at the same time, the externally sleeved sealing ring and its protrusion one and protrusion two further lock and seal the outside of the interface, forming a double protection of internal and external, which greatly improves the water tightness and long-term reliability of the interface and effectively eliminates leakage problems.

[0023] 2. In this utility model, a support ring made of rigid material and an extension block designed to be inserted into the pipes at both ends form a robust internal bridging structure at the pipe connection. This structure greatly enhances the bending and shear resistance of the interface, effectively preventing pipe breakage caused by foundation settlement or external forces. The entire structure consists of prefabricated components, and the connection can be completed through simple socketing and wedge self-locking without complicated tools. The installation process is quick and convenient, significantly improving construction efficiency and connection stability. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0027] Reference Figure 1 - Figure 4This utility model provides an embodiment of a quick-sealing interface structure for drainage pipes, including a pipe 1 as the active connection end and a pipe 2 as the receiving connection end. One end of the pipe 1 is provided with a socket 3 for insertion, and one end of the pipe 2 is provided with a socket 4 for receiving. In the installed state, the socket 3 is tightly inserted into the socket 4. At the connection between the socket 3 and the socket 4, in order to achieve functional differentiation and cooperation, a rubber sealing gasket 6 for forming the main seal and a support ring 9 for providing structural strength are provided in sequence. In addition, a sealing component for enhancing the sealing effect is provided outside the rubber sealing gasket 6. The sealing assembly specifically includes wedge 7 and wedge 8. One side of wedge 7 is firmly fixed to one side of the outer wall of the rubber gasket 6, while one side of wedge 8 is fixed to the other side of the outer wall of the rubber gasket 6. Their function is that, during insertion, both wedge 7 and wedge 8 are inserted into the socket 4, effectively filling and compressing the gap between the spigot 3 and the socket 4 through their wedge-shaped structure. To ensure that the rubber gasket 6 is accurately guided and protected during installation, it is wrapped around the spigot 3, away from its foremost end. To ensure a more uniform distribution of radial sealing force, two wedges 8 are designed and symmetrically arranged along the upper and lower sides of the pipe cross-section. To ensure the integrity of the components and simplify the installation process, the rubber sealing gasket 6, wedge 1 7, and wedge 2 8 are designed as an integral molded structure. To strengthen the weak links of the pipe connection from the inside, extension blocks 10 that act as bridges are fixedly connected to both ends of the support ring 9. One extension block 10 is inserted into the interior of pipe 1, and the other extension block 10 is inserted into the interior of pipe 2.

[0028] Specifically, the integrated rubber sealing gasket 6, wedge 1 7, and wedge 2 8 automatically form a multi-point wedge-type seal during pipe socket connection, effectively ensuring the internal watertightness of the interface. Simultaneously, the support ring 9 with extension block 10 forms a rigid bridge inside the interface, greatly enhancing the structural strength and bending resistance of the connection, effectively preventing damage to the interface due to external forces.

[0029] Reference Figure 1 - Figure 4To ensure its supporting effect, the support ring 9 is made of rigid materials such as metal or high-strength engineering plastics. Its core function is to provide stable rigid support for the connection between pipe 1 and pipe 2, so as to effectively resist external stress and prevent the connection from breaking. In order to construct a second seal outside the interface, a sealing ring 11 is tightly fitted on the outer wall of the support ring 9. In order to enhance the local clamping force, protrusion 5 and protrusion 12 are specially provided on the inner wall of the sealing ring 11. In order to ensure the integrity of the structure and the convenience of installation, protrusion 5 and protrusion 12 are designed as an integral molded structure with the sealing ring 11, and in order to ensure the uniform distribution of sealing pressure, they are arranged symmetrically from left to right. In order to extend the reinforcement of the support ring 9 into the inside of the pipe, the extension block 10 is set at the circumferential edge of the support ring 9, and in order to ensure the structural strength and the effectiveness of force transmission, it is integrally molded with the support ring 9.

[0030] Specifically, the rigid support ring 9 provides support for the interface, preventing breakage at the interface, while the integrally formed sealing ring 11 and the symmetrically arranged protrusions 5 and 12 form a second, robust external sealing barrier. This structure not only prevents breakage at the pipe connection through physical support, but also effectively seals off all potential external leakage paths through the compression and engagement of multiple sealing points, including wedge 7, wedge 8, protrusion 5, and protrusion 12. Working in conjunction with the internal rubber sealing gasket 6, it ensures the high stability and reliable sealing of the entire interface structure.

[0031] Working principle: When the drainage pipe is needed, the installation preparation is first carried out by installing the one-piece molded rubber sealing gasket 6, wedge 1 7 and wedge 2 8 inside the socket 4. Secondly, when connecting the pipes, the spigot 3 of pipe 1 is aligned with the socket 4 of pipe 2 and inserted. As the spigot 3 is inserted into the socket 4, the integrally formed rubber sealing gasket 6, wedge 1 7 and wedge 2 8 enter the gap inside the socket 4 along with the spigot 3. Since wedge 1 7 and the two symmetrical wedge 2 8 all have a wedge-shaped structure, they will be radially squeezed by the inner wall of the socket 4 during the insertion process, thereby tightly filling and pressing the gap between the pipe walls, forming the first reliable internal multi-point contact seal. Finally, the support ring 9, made of rigid material, slides into the interior of pipe 1 and pipe 2 through the extension blocks 10 at both ends, forming an internal rigid skeleton that penetrates the interface at the connection of the two pipes. This skeleton structure provides the interface with strong bending and shear resistance. The sealing ring 11, which is sleeved on the support ring 9 outside the interface, and its integrally formed protrusions 5 and 12 tightly fit with the outer walls of the socket 3 and the inlet 4. The presence of protrusions 5 and 12 increases the complexity of the contact pressure and sealing path, forming a second external sealing barrier and playing an auxiliary locking role for the interface.
