Description

Technical Field

[0001] This utility model relates to the field of pipe technology, specifically to an MPP pipe with a quick connector. Background Technology

[0002] MPP pipe is a type of protective conduit for electrical wires and cables. Using modified polypropylene (PP) as its main raw material, MPP pipe possesses characteristics such as high temperature resistance and external pressure resistance, making it particularly suitable for laying pipelines and cables in special locations such as roads, railways, buildings, and riverbeds. During installation, MPP pipes need to traverse different terrains and environments; therefore, multiple sections of MPP pipe need to be connected to form a continuous pipeline system. This connection ensures that the cable remains continuous and stable throughout the entire route, avoiding interruptions caused by changes in terrain or obstacles.

[0003] The most common connection method for MPP pipes is hot-melt connection, which involves using a special hot-melt welding machine to heat the two MPP pipe ends to a molten state and then quickly connect them together. This connection method requires carrying the hot-melt welding machine, which increases the burden. In addition, defects such as bubbles, cracks, and scratches on the surface of MPP pipes can have an adverse effect on the hot-melt connection. During the hot-melt process, it may not be able to melt synchronously with other parts, resulting in weak links at the weld surface and affecting the quality of the MPP in subsequent use.

[0004] Therefore, we have made improvements and proposed an MPP pipe with quick-connect fittings. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1 to 5 As shown, this utility model discloses an MPP pipe with a quick connector, comprising two MPP pipe bodies 1, a second connector 3, and two first connectors 2. The first connectors 2 are fixedly connected to both ends of the second connector 3, and the first connectors 2 and the second connectors 3 form a connector. The two MPP pipe bodies 1 are connected by the connector, which is simple and quick to operate. Compared with the use of a hot melt welding machine, this method can avoid weak points in the connection, and also eliminates the need to carry a hot melt welding machine at all times, reducing the burden.

[0024] One end of the MPP pipe body 1 passes through the first connection end 2 and extends into the second connection end 3. There is a gap between the near ends of the two MPP pipe bodies 1 to avoid mutual interference during installation. Multiple threaded rods 5 are evenly arranged circumferentially on the surface of the first connection end 2. A clamping plate 6 is provided at the bottom end of the threaded rod 5 and is attached to the surface of the MPP pipe body 1. The clamping plate 6 can be moved by manually rotating the threaded rod 5. After the MPP pipe body 1 enters the first connection end 2 and the second connection end 3, the clamping plate 6 clamps and fixes the MPP pipe body 1.

[0025] Two collars 8 are symmetrically installed on both ends of the surface of the second connection end 3. A sealing gasket 9 is provided at the end of the collar 8 closest to the MPP pipe body 1. There is sealant between the two collars 8. Before the MPP pipe body 1 is placed into the first connection end 2 and the second connection end 3, the collars 8 and the sealing gasket 9 are first installed on the MPP pipe body 1. Then, the collars 8 and the sealing gasket 9 are inserted into the first connection end 2 and the second connection end 3 together with the MPP pipe body 1. The sealant is used to seal the connection between the MPP pipe body 1 and the second connection end 3 between the two collars 8, thereby enhancing the sealing performance and the tightness and stability of the connection.

[0026] Multiple mounting holes 7 are evenly distributed circumferentially on the surface of the connecting end 2, and the threaded rod 5 is threaded into the mounting holes 7. Telescopic rods 11 are fixedly installed on the inner wall of the connecting end 2 and the surface of the clamping plate 6, respectively, at both ends of the threaded rod 5. The bottom end of the threaded rod 5 is rotatably connected to the surface of the clamping plate 6, and the end of the clamping plate 6 near the MPP pipe body 1 has a rubber pad. The telescopic rod 11 is a common telescopic structure with an internal spring, which will not be described in detail here. The telescopic rod 11 can extend and retract accordingly as the clamping plate 6 moves.

[0027] The collar 8 has a groove on the side near the MPP pipe. The sealing gasket 9 consists of two parts, left and right, with a gap between them. Both parts of the sealing gasket 9 are connected within the groove, and one end of the sealing gasket 9 is pressed against the surface of the MPP pipe body 1. The sealing gasket 9 pressing against the surface of the MPP pipe body 1 provides a sealing effect.

[0028] Fixing holes are provided in the groove and on the surface of the MPP pipe body 1. The fixing hole in the groove extends through the groove and has an installation area at its top, and is located between the two sealing gaskets 9. A fastening bolt 10 is installed in the fixing hole, with the top of the fastening bolt 10 located within the installation area to prevent the fastening bolt 10 from scratching the inner wall of the second connection end 3. The top surface of the collar 8, located at both ends of the fastening bolt 10, also contacts the inner wall of the second connection end 3 through the sealing gaskets 9. The fastening bolt 10 enhances the tightness of the connection. The sealing gasket 9 is made of rubber and acts as a barrier against sealant.

[0029] A sealant inlet 4 is provided on the surface of the second connector 3, located between the two collars 8. Sealant, specifically PVC sealant, is injected into the second connector 3 through the inlet 4. The sealant is injected into the second connector 3 through the inlet 4. Because there is a gap between the surface of the MPP pipe body 1 and the inner wall of the second connector 3, the sealant can easily enter and provide a sealing connection. An existing sealing plug can be used to seal the inlet 4 to prevent the sealant from flowing out before it dries.

[0030] During operation, the two MPP pipe bodies 1 are respectively clamped into the connecting end 2 and the connecting end 3. The clamping plate 6 in the connecting end 2 can clamp and fix the MPP pipe body 1, enhancing the stability and tightness of its connection with the connecting end 2. By injecting PVC special glue into the glue injection port 4, the MPP pipe body 1 and the connecting end 3 are connected together, further enhancing the tightness of the connection between the MPP pipe body 1 and the connecting end 3, and at the same time playing a sealing role. The two MPP pipe bodies 1 are connected together in this way, which is simple to operate.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
