Description

Technical Field

[0001] This utility model relates to the field of plastic pipe technology, specifically to a splicable plastic pipe. Background Technology

[0002] Splicable plastic pipes are a type of fluid transport pipe that allows for the detachable and fixed connection of single or multiple pipe sections through a specific connection structure. Their core function is to meet the needs of pipeline laying with different lengths, routes, and diameters through splicing and assembly. They are widely used in building water supply and drainage, municipal pipe networks, agricultural irrigation, and chemical media transportation. These pipes typically use high-molecular materials such as polyethylene, polypropylene, and PVC as the base material, possessing characteristics such as lightweight, corrosion resistance, and low cost. Their splicing structure directly determines installation efficiency, sealing performance, and reusability.

[0003] Existing splicing structures are mostly rigidly fixed, and the angle cannot be finely adjusted after the pipe body is spliced. When there are slight deviations in the pipeline laying path or when it is necessary to avoid obstacles, additional elbow fittings are required, increasing construction costs and installation difficulty. Moreover, splicing plastic pipes of different diameters requires special adapters, which are numerous and have high inventory management costs. Furthermore, multiple adapters can increase the risk of leakage and reduce the overall flowability of the pipeline. Therefore, a splicable plastic pipe is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a splicable plastic pipe is provided. This technical solution solves the problems mentioned in the background art, such as the inability to finely adjust the angle of the pipe body after splicing and the need to equip special adapters for splicing plastic pipes of different diameters.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A splicable plastic pipe includes a pipe body. The outer surface of the pipe body is fixedly connected with a symmetrically distributed first rotating groove and a second rotating groove. The first rotating groove and the second rotating groove are respectively rotatably connected to a first universal ball joint and a second universal ball joint. The first universal ball joint and the second universal ball joint are both provided with through holes. The left end of the first universal ball joint is provided with a threaded connector, and the right end of the second universal ball joint is provided with a threaded connector sleeve.

[0006] Preferably, the threaded connector includes a first threaded segment connected to the left end of the first universal ball joint, the left end of the first threaded segment being connected to a second threaded segment, and the left end of the second threaded segment being connected to a third threaded segment.

[0007] Preferably, the cross-sectional dimensions of the first threaded segment, the second threaded segment, and the third threaded segment decrease sequentially.

[0008] Preferably, the threaded connection sleeve includes a first threaded sleeve connected to the right end of the second universal ball joint, a second threaded sleeve connected to the right end of the first threaded sleeve, and a third threaded sleeve connected to the right end of the second threaded sleeve.

[0009] Preferably, the cross-sectional dimensions of the first threaded sleeve, the second threaded sleeve, and the third threaded sleeve increase sequentially.

[0010] Preferably, a first flexible hose is connected between the pipe body and the right end of the first universal ball joint.

[0011] Preferably, a second flexible hose is connected between the left end of the pipe body and the second universal ball joint.

[0012] Compared with the prior art, this utility model provides a splicable plastic tube, which has the following beneficial effects: This utility model, by setting a universal ball joint and using a connecting hose, enables the spliced ​​pipe body to achieve small-angle adjustment, adapting to the "non-linear" installation requirements in complex installation environments, and avoiding installation rework or pipe stress damage caused by fixed angles.

[0013] This utility model, by setting a three-section threaded connector and a threaded connecting sleeve, can directly connect to plastic pipes of different specifications and diameters without the need for additional special adapters, thereby reducing usage costs and improving the versatility and convenience of splicing.

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art.

[0017] Reference Figures 1-4 As shown, a splicable plastic pipe includes a pipe body 1. The pipe body 1 serves as the core load-bearing structure for fluid transportation, providing a basic transportation channel and also providing an installation carrier for other splicing and adjustment components. The outer surface of the pipe body 1 is fixedly connected with symmetrically distributed first rotating grooves 2 and second rotating grooves 3. The interiors of the first rotating grooves 2 and second rotating grooves 3 are respectively rotatably connected to a first universal ball joint 4 and a second universal ball joint 5. The first rotating groove 2 provides axial limiting and rotational support for the first universal ball joint 4, allowing the ball joint to rotate while preventing it from falling off, providing a structural basis for fine-tuning the pipe angle. The second rotating groove 3 provides limiting and rotational support for the second universal ball joint 5, enabling angle adjustment at both ends of the pipe. Both the first universal ball joint 4 and the second universal ball joint 5 have through holes inside, allowing fluid to flow through them. The rotational characteristics of the ball joints enable fine-tuning of the pipe angle after splicing, and the flexible hose compensates for angular displacement. A threaded connector 6 is provided at the left end of the first universal ball joint 4, and a threaded connector sleeve 7 is provided at the right end of the second universal ball joint 5.

[0018] Furthermore, the threaded connector 6 includes a first threaded section 601 connected to the left end of the first universal ball joint 4, a second threaded section 602 connected to the left end of the first threaded section 601, and a third threaded section 603 connected to the left end of the second threaded section 602. The cross-sectional dimensions of the first threaded section 601, the second threaded section 602, and the third threaded section 603 decrease sequentially. The threaded connector 6, through its three threaded structures with sequentially decreasing cross-sectional dimensions, can adapt to plastic pipes of different diameters to be spliced, achieving multi-specification docking without the need for special adapters.

[0019] Furthermore, the threaded connection sleeve 7 includes a first threaded sleeve 701 connected to the right end of the second universal ball joint 5, a second threaded sleeve 702 connected to the right end of the first threaded sleeve 701, and a third threaded sleeve 703 connected to the right end of the second threaded sleeve 702. The cross-sectional dimensions of the first threaded sleeve 701, the second threaded sleeve 702, and the third threaded sleeve 703 increase sequentially. The threaded connection sleeve 7 and the threaded connection head 6 have complementary structures, which can directly connect plastic pipes of different diameters, and can also engage with the threaded connection head 6 of another plastic pipe to realize the continuous splicing of multiple pipes.

[0020] Furthermore, a first flexible hose 8 is connected between the right end of the pipe body 1 and the first universal ball joint 4. The first flexible hose 8 has flexible deformation capability to compensate for the angular displacement when the first universal ball joint 4 rotates, and at the same time seals and connects the pipe body 1 and the first universal ball joint 4 to prevent fluid leakage. A second flexible hose 9 is connected between the left end of the pipe body 1 and the second universal ball joint 5. The second flexible hose 9 flexibly compensates for the angular displacement of the second universal ball joint 5 and seals and connects the pipe body 1 and the second universal ball joint 5.

[0021] Working principle: When using this utility model, firstly, select the corresponding thread segment for the threaded connector 6 and the matching threaded sleeve for the threaded connector sleeve 7 according to the pipe diameter to be spliced. Tighten and fix one pipe to be spliced ​​with the selected thread segment of the threaded connector 6, and tighten and fix the other pipe to be spliced ​​with the selected threaded sleeve of the threaded connector sleeve 7. If multiple pipes need to be spliced ​​continuously, directly engage and tighten the threaded connector sleeve 7 of the previous pipe with the threaded connector 6 of the next pipe. According to the installation space requirements, rotate the two universal ball joints to adjust the pipe installation angle. The hose bends naturally with the angle until the ideal installation position is reached. After the splicing is completed, fluid is introduced to test the sealing performance. After confirming that there is no leakage and the angle is stable, it can be put into normal use.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
