Description

Technical Field

[0001] This utility model belongs to the technical field of water pipe pre-embedded components, and in particular relates to a drainage pipe pre-embedded component. Background Technology

[0002] In building water supply and drainage engineering, the pre-embedded components of drainage pipes are the core components for realizing the concealed installation of pipes, and their performance directly affects the sealing, stability and convenience of later maintenance of the drainage system.

[0003] Currently, the pre-embedded components of drainage pipes on the market are concealed in walls or the ground. Due to the lack of obvious markings, it is difficult to quickly locate the components during installation and maintenance, which increases time costs and construction difficulty. In addition, the joint between the components and cement mortar is mostly a smooth structure with low interlocking strength. It is prone to loosening due to building settlement or temperature changes, which can cause the pipe to shift and affect the smoothness of drainage. In addition, during the construction of underground pipelines, drainage pipes and cables often need to be laid out simultaneously. However, existing components do not have dedicated cable restraint structures, and cables are prone to getting tangled or squeezed with pipes, posing safety hazards and making later maintenance difficult.

[0004] To address the aforementioned issues, there is an urgent need for a drainage pipe pre-embedded component that features efficient sealing, convenient positioning, stable fixing, and cable management functions, in order to meet the high-quality requirements of building engineering for pre-embedded pipes. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a pre-embedded component for drainage pipes, which solves the problems of difficult positioning, poor sealing and unstable fixing of traditional pre-embedded components.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a pipe body, and connecting pipes are fixedly provided at both ends of the pipe body. The connecting pipe includes an outer wide part and an inner plug part. A drain pipe is inserted and installed between the outer side of the inner plug part and the inner side of the outer wide part. A fluorescent indicator ring and a rubber leak-proof part are also embedded on the connecting pipe. A pair of limiting parts are also provided on the outer side of the pipe body.

[0007] Furthermore, the limiting member is a U-shaped metal part, which is disposed opposite to and connected to the two sides of the cylindrical body of the pipe fitting. The U-shaped groove structure on the limiting member is used to enhance the fixing effect with cement mortar.

[0008] Furthermore, the inner side of the U-shaped groove structure can also be used for underground cabling, which also has a certain limiting effect on the cables.

[0009] Furthermore, the fluorescent indicator ring is a ring-shaped hollow plastic tube, the inner cavity of which is filled with a light-emitting self-luminous material. The fluorescent indicator ring is embedded in the ring-shaped groove on the outer surface of the outer part and connected by adhesive.

[0010] Furthermore, the rubber leak-proof component is a ring-shaped rubber ring, which is embedded in the annular groove on the inner side of the inner connector and connected by adhesive.

[0011] Furthermore, the inner surface of the annular rubber ring is provided with several annular protrusions.

[0012] Furthermore, the annular protrusions fit tightly against the outer surface of the drain pipe to form a seal and prevent leakage.

[0013] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, the annular protrusion of the rubber leak-proof component is interference-engaged with the outer surface of the drain pipe to form multiple sealing defenses, effectively avoiding the problem of poor fit of traditional sealing structures. It can still maintain good sealing performance under water pressure impact and reduce the risk of water leakage. 2. In this utility model, the fluorescent indicator ring uses a photoluminescent self-luminous material, which can emit light automatically without an external power supply during installation and maintenance. The luminous markings can quickly locate the component position, improve installation and maintenance efficiency, and significantly reduce time costs. 3. In this utility model, the U-shaped limiting component increases the contact area with cement mortar, and the U-shaped groove can form an interlocking structure with the mortar, effectively resisting the risk of loosening caused by building settlement or temperature changes, and ensuring the long-term stability of components and pipes. 4. In this utility model, the U-shaped groove of the limiting component has both fixing and cable limiting functions, which can orderly store underground cables in the groove, avoid cables from getting tangled and squeezed by pipes, and improve the standardization and safety of pipeline layout.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Combination Figures 1 to 4 The diagram shows a pre-embedded drainage pipe component, which includes a pipe body 1. Both ends of the pipe body 1 are fixedly provided with connecting pipes 2. The connecting pipes 2 include an outer wide part 21 and an inner plug part 22. The drainage pipe is inserted and installed between the outer side of the inner plug part 22 and the inner side of the outer wide part 21. The connecting pipes 2 are also embedded with a fluorescent indicator ring 3 and a rubber leak-proof part 4. A pair of limiting parts 5 are also provided on the outer side of the pipe body 1.

[0018] Among them, the limiting member 5 is a U-shaped metal part. The limiting member 5 is set opposite to the two sides of the cylinder body of the pipe body 1 and installed and connected. The U-shaped groove structure on the limiting member 5 is used to enhance the fixing effect with cement mortar.

[0019] The inner side of the U-shaped channel structure can also be used for underground cabling, and it also has a certain limiting effect on the cables.

[0020] The fluorescent indicator ring 3 is a ring-shaped hollow plastic tube, and its inner cavity is filled with a light-emitting self-luminous material. The fluorescent indicator ring 3 is embedded in the ring-shaped groove on the outer surface of the outer part 21 and connected by adhesive.

[0021] The rubber leak-proof component 4 is a ring-shaped rubber ring, which is embedded in the annular groove on the inner side of the inner connector 22 and connected by adhesive.

[0022] The inner side of the ring-shaped rubber ring is provided with several annular protrusions 41.

[0023] The annular protrusion 41 fits into the outer surface of the drain pipe to form a seal and prevent leakage.

[0024] Working principle: During use, the assembled pre-embedded components are placed in the preset position, and cement mortar is filled around the components of the limiting member 5. The cement mortar and the U-shaped groove form an interlocking structure. After the mortar cures, the limiting member 5 is tightly bonded to the mortar, achieving stable fixation of the components and preventing loosening later. The end of the drain pipe is inserted into the annular slot between the outer side of the inner connector 22 and the inner side of the outer connector 21. During insertion, the outer surface of the drain pipe is squeezed against the annular protrusion 41 of the rubber leak-proof component 4. Due to elastic deformation, the annular protrusion 41 fits tightly against the outer surface of the drain pipe, forming an interference fit and achieving a seal to prevent leakage. During maintenance, the fluorescent indicator ring 3 absorbs light and emits light autonomously in the dark, allowing for quick location of the component through the luminous indicator. In addition, underground cables can be threaded into the U-shaped groove of the limiting member 5 to achieve orderly cable storage and avoid interference with the pipeline.
