Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of splicing and reinforcement, and more specifically, to a pipe splicing and reinforcement device. Background Technology
[0002] PVC conduits are widely used to protect wires and cables in building electrical installations and various wiring projects. However, problems often arise at the joints of PVC conduits during actual use, which has led to the development of joint reinforcement components. These components are important devices used to enhance the strength and stability of PVC conduit joints. Strengthening the connection between conduits, improving sealing, and increasing stability have become crucial issues.
[0003] With the increasing number of electrical devices and the growing demand for stable power supply, higher requirements are being placed on the safety and reliability of PVC conduit splicing. A solution is needed to ensure secure, well-sealed, and stable conduit connections to guarantee the normal operation and lifespan of electrical wires and cables. Traditional PVC conduit splicing typically involves direct splicing or adhesive bonding, which, while relatively quick and efficient and convenient for installation to some extent, still presents the following problems:
[0004] Traditional PVC conduit splicing mainly involves expanding the end of one conduit and then inserting the end of another conduit into the expanded opening. During the heat expansion process, cracks or damage can easily occur at the expanded end. Over time and with environmental changes, aging and cracking may occur, leading to connection failure and making it difficult to achieve a complete seal. Furthermore, the overall stability of the spliced conduit is poor, making it prone to shaking and displacement, which may cause the conduit to deform or be damaged during later use. Utility Model Content
[0005] To overcome the shortcomings of the prior art in terms of the instability of the splicing joints of conduits, this utility model provides a pipe splicing reinforcement device that can reinforce spliced conduits.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0007] A pipe fitting splicing and reinforcement device includes a first pipe fitting, a second pipe fitting, a first reinforcement component, and a second reinforcement component;
[0008] The first pipe fitting has a connecting flare at one end, the inner diameter of which matches the outer diameter of the second pipe fitting. The outer surface of the first pipe fitting is fitted with a first reinforcing component, and the outer surface of the second pipe fitting is fitted with a second reinforcing component. The first reinforcing component and the second reinforcing component are detachably connected.
[0009] Compared with the prior art, the beneficial effects of this utility model's technical solution are:
[0010] By setting a connecting flare, a transition area is created at the connection point of the first and second pipe fittings, enabling better connection of the two conduits. The first reinforcing sleeve provides a robust layer of protection at the conduit connection flare, while the second reinforcing sleeve provides a second layer of protection at the conduit connection. Used in conjunction with the first reinforcing sleeve, the strength and stability of the conduit splice are further enhanced, making the spliced conduits less prone to loosening or even separation, and increasing the sealing and overall stability of the spliced conduits.

Detailed Implementation
[0018] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent.
[0019] To better illustrate this embodiment, some parts in the accompanying drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions;
[0020] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings.
[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0022] Example 1
[0023] This embodiment proposes a pipe splicing and reinforcement device. Figure 1 This is a cross-sectional view of the pipe splicing and reinforcement device proposed in this embodiment; Figure 2 This is a schematic diagram of the pipe splicing and reinforcement device proposed in this embodiment; Figure 3 This is a schematic diagram of the structure of the first and second pipe fittings proposed in this embodiment; Figure 4 This is a schematic diagram of the structure of the first and second reinforcing sleeves proposed in this embodiment; Figure 5 This is a cross-sectional view of the first and second reinforcing sleeves proposed in this embodiment.
[0024] like Figures 1-5 As shown, this embodiment proposes a pipe splicing reinforcement device, including a first pipe 1, a second pipe 3, a first reinforcement component, and a second reinforcement component;
[0025] Wherein, one end of the first pipe fitting 1 is provided with a connecting flare 2, the inner diameter of the connecting flare 2 is matched with the outer diameter of the second pipe fitting 3, the outer surface of the first pipe fitting 1 is fitted with a first reinforcing component, the outer surface of the second pipe fitting 3 is fitted with a second reinforcing component, and the first reinforcing component and the second reinforcing component are detachably connected.
[0026] In the specific implementation process, by setting a connecting flare, a transition area is created at the connection point of the first and second pipe fittings, which can better realize the connection of the two pipes. The setting of the first reinforcing sleeve provides a solid layer of protection at the pipe connection flare, and the setting of the second reinforcing sleeve provides a second layer of protection at the pipe connection point. When used in conjunction with the first reinforcing sleeve, the strength and stability of the pipe splice are further enhanced, making the spliced pipe less likely to loosen or even separate, and increasing the sealing and overall stability of the spliced pipe.
[0027] As an example, the first fitting 1 and the second fitting 3 can both be conduits, and the conduits can be made of PVC material.
[0028] As an example, by setting the connecting flare 2, a transition area is provided at the connection point between the first fitting 1 and the second fitting 3, which can better realize the connection of the two conduits, reduce the problem of loose connection caused by uneven conduit ends, and can be applied to splicing PVC conduits of different specifications. It has strong versatility and can meet the needs of various projects and home decoration.
[0029] In an optional embodiment, the first reinforcement component includes a first reinforcement sleeve 4, and the first reinforcement sleeve 4 has a first flared access section 5 at one end near the connecting flared end 2;
[0030] The second reinforcement component includes a second reinforcement sleeve 6, and a second flared access section 7 is provided at one end of the second reinforcement sleeve 6 near the first flared access section 5;
[0031] The outer diameter of the first flared access section 5 matches the inner diameter of the second flared access section 7.
[0032] As an example, by inserting and removing the first flared access section 5 into the second flared access section 7, a detachable connection between the first reinforcement component and the second reinforcement component can be achieved, ensuring a precise connection between the first reinforcement structure and the second reinforcement structure. This precise dimensional fit allows the two reinforcement structures to be perfectly nested together, forming a continuous and robust whole, further enhancing the strength and stability of the conduit splice.
[0033] As an example, the first reinforcing sleeve 4 provides a robust protection at the conduit connection flare. The first flare access section 5 is opened at one end near the connection flare 2, which can fit tightly with the connection flare 2, ensuring that there is no gap between the reinforcing structure and the conduit, thereby enhancing the tightness of the connection and preventing the conduit from loosening or falling off during use.
[0034] As an example, the second reinforcing sleeve 6 provides a second layer of protection for the conduit connection, and when used in conjunction with the first reinforcing sleeve 4, it further enhances the strength and stability of the conduit joint.
[0035] In an optional embodiment, the second flared access section 7 is provided with a grouting hole 12, and there is a gap between the second flared access section 7 and the second pipe fitting 3, the gap being filled with reinforcing material.
[0036] As an example, when further reinforcement is needed, filling material (reinforcing material) can be injected into the second reinforcing sleeve 6 through the grouting hole 12. After the filling material solidifies, it can increase the strength and stability of the reinforced structure, and at the same time improve the sealing of the pipe joint, preventing moisture and impurities from entering the pipe.
[0037] As an example, filling material is injected into the second reinforcing sleeve 6 through the grouting hole 12. After the filling material solidifies, it can increase the strength and stability of the reinforced structure, and at the same time improve the sealing of the pipe joints, preventing moisture and impurities from entering the pipe. If a problem is found at the pipe connection during use, it can be repaired by injecting repair material through the grouting hole without disassembling the entire reinforcement component, which greatly reduces maintenance costs and difficulty, enhances the connection strength between pipes, improves sealing, and increases stability.
[0038] In an optional embodiment, the first reinforcing component further includes a first threaded tube 8, and the second reinforcing component further includes a second threaded tube 9;
[0039] The first flared access section 5 is connected to the first threaded pipe 8, and the second flared access section 7 is connected to the second threaded pipe 9. The first reinforcement component and the second reinforcement component are detachably connected through the first threaded pipe 8 and the second threaded pipe 9.
[0040] In an optional embodiment, the first threaded tube 8 is an externally threaded tube, and the second threaded tube 9 is an internally threaded tube.
[0041] As an example, a detachable connection between the first reinforcement component and the second reinforcement component can be achieved by screwing the external threaded tube into and out of the internal threaded tube. The design of the external and internal threaded tubes enhances the structural strength of the first and second reinforcement components and serves as a positioning tool for installation.
[0042] In an optional embodiment, a limiting ring 10 is installed at the connection between the first flared access section 5 and the first threaded pipe 8; an interface groove 11 is opened at the end of the second threaded pipe 9 away from the second flared access section 7, and the limiting ring 10 matches the interface groove 11.
[0043] Example 2
[0044] This embodiment is an improvement on the pipe splicing and reinforcement device proposed in Embodiment 1.
[0045] Figure 2 This is a schematic diagram of the second structure of the pipe splicing and reinforcement device proposed in this embodiment.
[0046] This embodiment proposes a pipe splicing and reinforcement device, including a first pipe 1, a second pipe 3, a first reinforcement component, and a second reinforcement component;
[0047] Wherein, one end of the first pipe fitting 1 is provided with a connecting flare 2, the inner diameter of the connecting flare 2 is matched with the outer diameter of the second pipe fitting 3, the outer surface of the first pipe fitting 1 is fitted with a first reinforcing component, the outer surface of the second pipe fitting 3 is fitted with a second reinforcing component, and the first reinforcing component and the second reinforcing component are detachably connected.
[0048] In the specific implementation process, by setting a connecting flare, a transition area is created at the connection point of the first and second pipe fittings, which can better realize the connection of the two pipes. The setting of the first reinforcing sleeve provides a solid layer of protection at the pipe connection flare, and the setting of the second reinforcing sleeve provides a second layer of protection at the pipe connection point. When used in conjunction with the first reinforcing sleeve, the strength and stability of the pipe splice are further enhanced, making the spliced pipe less likely to loosen or even separate, and increasing the sealing and overall stability of the spliced pipe.
[0049] In an optional embodiment, a fastening component is fitted onto the outer surface of the first reinforcement component and / or the second reinforcement component.
[0050] Figure 6 This is a schematic diagram of the fastening assembly proposed in this embodiment, as shown below. Figure 6 As shown, in an optional embodiment, the fastening assembly includes a first clamping ring 13 and a second clamping ring 14. Both sides of the first clamping ring 13 and the second clamping ring 14 are provided with connecting plates 15, and the connecting plates 15 of the first clamping ring 13 and the second clamping ring 14 are detachably connected.
[0051] In an optional embodiment, the fastening assembly further includes a connecting block, the connecting plate having a connecting hole 16, the connecting block matching the connecting hole 16, and the connecting plate 15 of the first clamping ring 13 and the connecting plate 15 of the second clamping ring 14 being detachably connected through the connecting hole 16 and the connecting block.
[0052] As an example, when the clamping ring is tightened, it exerts uniform pressure on the reinforcing components and the conduit, making the connection between the components tighter, further improving the sealing performance and preventing external impurities from entering the conduit.
[0053] In one optional embodiment, a fixing plate 17 is provided on the outer surface of the second clamping ring, and the fixing plate 17 has a plurality of fixing holes.
[0054] As an example, the fixing plate 17 can be a grounding plate, and the fixing hole can be a wall locking hole. The conduit can be fixed to the ground through the grounding plate and the wall locking hole, thereby increasing the stability of the conduit.
[0055] It is understood that the pipe splicing reinforcement device in this embodiment is an improvement on the pipe splicing reinforcement device in embodiment 1. The options in embodiment 1 are also applicable to this embodiment, so they will not be described again here.
[0056] Example 3
[0057] This embodiment proposes a specific implementation example based on the pipe splicing and reinforcement device proposed in Embodiments 1 and 2.
[0058] This embodiment proposes a pipe splicing reinforcement device, including a first pipe 1 and a second pipe 3. One end of the first pipe 1 is provided with a connecting flared end 2. A first reinforcement component is sleeved on the outside of the first pipe 1, and a second reinforcement component is sleeved on the outside of the second pipe 3. A clamp structure is sleeved on the outside of both the first reinforcement component and the second reinforcement component.
[0059] Furthermore, the first reinforcing component includes a first reinforcing sleeve 4, and a first flared access section 5 is provided at one end of the first reinforcing sleeve 4 near the connecting flared end 2. The surface of the first flared access section 5 is provided with external threads, and a limit ring 10 is fixedly connected to one side of the connection between the first flared access section 5 and the external threads.
[0060] In use, the first reinforcing sleeve 4 is fitted onto the surface of the first pipe fitting 1, wrapping the first pipe fitting 1, and the first flared access section 5 is fitted onto the surface of the connecting flared section 2, wrapping the connection between the first pipe fitting 1 and the second pipe fitting 3, thus initially enhancing the reinforcement effect. The limiting ring 10 is prepared for connection with the second reinforcing component during installation.
[0061] Furthermore, the second reinforcement component includes a second reinforcement sleeve 6, with a second flared access section 7 at one end of the second reinforcement sleeve 6 near the first flared access section 5, an internal thread inside the second flared access section 7, an interface groove 11 at the connection between the second flared access section 7 and the internal thread, and a grouting hole 12 at the upper end of the second flared access section 7.
[0062] In use, the second flared access section 7 is fitted onto the surface of the first flared access section 5. The second flared access section 7 is tightened by the internal and external threads, and the interface groove 11 is close to the limiting ring 10 to restrict the position of the second reinforcing component. After installation, cement is poured into the cavity through the grouting hole 12 at the upper end of the second flared access section 7 to fill the internal cavity.
[0063] Furthermore, the clamp structure (fastening assembly) includes a clamping ring, with connecting plates fixedly connected to both sides of the clamping ring, and connecting blocks threaded to both ends of the surface of the connecting plates;
[0064] During use, the tightness of the clamping ring can be controlled by adjusting the position of the connecting block on the connecting plate, thus adapting to different sizes of conduits and reinforcement structures.
[0065] Furthermore, the outer diameter of the connecting flare 2 matches the inner diameter of the first flare access section 5, and the outer diameter of the first flare access section 5 matches the inner diameter of the second flare access section 7.
[0066] When in use, the components can be quickly and accurately assembled in the correct order without much adjustment or correction.
[0067] Furthermore, the bottom of the clamping ring is fixedly connected to a ground plate, and the surface of the ground plate has four wall-locking holes;
[0068] When using it, tighten the clamps to secure the conduit, connect the floor plate to the ground, and fix the conduit to the ground.
[0069] In this embodiment, the following steps are taken: First, the connecting flared end 2 of the first pipe fitting 1 is connected to the second pipe fitting 3, providing a preliminary stable foundation for the splicing of the conduit. Then, the first reinforcing sleeve 4 of the first reinforcing component is tightly fitted onto the surface of the connecting flared end 2 through the first flared access section 5. Next, the second reinforcing sleeve 6 of the second reinforcing component is engaged with the first reinforcing component through the second flared access section 7, with the internal thread spirally connected to the external thread of the first flared access section 5. The interface groove 11 abuts against the limiting ring 10, so that the two reinforcing structures are tightly combined and seamlessly connected. Cement or other filling materials are injected through the grouting hole 12 to improve the overall strength and sealing. Finally, the clamping ring 13 of the clamping structure tightly clamps the tail ends of the first reinforcing component and the second reinforcing component through the connecting plate 14 and the connecting block 15. Finally, the grounding plate 16 is fixed to the ground to achieve the reinforcement of the PVC conduit splicing.
