Description

A quick-disassembly PVC drainage pipe structure Technical Field

[0001] This utility model relates to the field of drainage pipe technology, specifically to a PVC drainage pipe structure that can be quickly disassembled. Background Technology

[0002] PVC drainage pipes are made primarily from sanitary-grade polyvinyl chloride (PVC) resin, with the addition of appropriate amounts of stabilizers, lubricants, fillers, and colorants. They are produced through extrusion molding using a plastic extruder and injection molding using an injection molding machine, followed by cooling, curing, shaping, inspection, and packaging processes. These pipes exhibit excellent surface hardness and tensile strength, resulting in a high safety factor. They can withstand certain external pressure and tensile forces and are not prone to breakage or damage under normal use. In the industrial sector, they are suitable for drainage systems in industrial plants and workshops, discharging wastewater and sewage generated during industrial production.

[0003] Existing PVC drainage pipes are widely used, but the installation and disassembly of PVC drainage pipes usually require the use of multiple bolts and clamps, and two PVC drainage pipes need to be moved so that their joints are close to each other before installation and disassembly can be carried out, which makes the installation and disassembly speed slow. Therefore, in order to address the above problems, a PVC drainage pipe structure that can be quickly disassembled is proposed. Summary of the Invention

[0025] Please refer to Figures 1-6. This utility model provides a technical solution:

[0026] A quick-disassembly PVC drainage pipe structure includes symmetrically arranged pipe bodies 1, a horizontally arranged telescopic pipe 2 between the two pipe bodies 1, symmetrically arranged connecting sleeves 3 fixedly connected to both ends of the telescopic pipe 2, a clamping assembly 4 on the outer side of the connecting sleeve 3, a horizontally arranged sleeve 5 on the inner side of the telescopic pipe 2, and symmetrically arranged connecting pipes 6 on the inner side of the sleeve 5. A first sealing ring 7 is fixedly connected to the outer side of the connecting pipe 6, a second sealing ring 8 fixedly connected to the outer side of the connecting pipe 6 on one side of the first sealing ring 7, and a fixing ring 9 fixedly connected to the outer side of the connecting pipe 6 between the first sealing ring 7 and the second sealing ring 8. The connecting sleeve 3 is located on the outer side of the pipe body 1 and fits tightly against the outer side of the pipe body 1. The fixing ring 9 is fixedly connected to the inner side of the connecting sleeve 3. The inner diameter of the sleeve 5 is the same as the inner diameter of the pipe body 1. The first sealing ring 7 and the second sealing ring 8 are the same shape and size. The outer side of the first sealing ring 7 fits tightly against the inner side of the pipe body 1, and the outer side of the second sealing ring 8 fits tightly against the inner side of the sleeve 5. The clamping assembly 4 includes symmetrically arranged connecting sleeves 6. The outer half-open ring 41 of sleeve 3 has a pressure plate 42 fixedly connected to its inner side. The two half-open rings 41 are hinged together by a hinge 43. The outer side of the two half-open rings 41 away from the hinge 43 is fixedly connected to a mounting groove plate 44. A bolt 45 is rotatably connected to the inner side of one mounting groove plate 44. The bolt 45 is inserted into the inner side of the other mounting groove plate 44. A nut 46 is threaded onto the outer side of the bolt 45. The pressure plate 42 is vertically aligned with the first sealing ring 7, and the inner side of the pressure plate 42 is tightly fitted to the outer side of the connecting sleeve 3. With the included telescopic tube 2, connecting sleeve 3, clamping assembly 4, sleeve 5, connecting tube 6, first sealing ring 7, second sealing ring 8, and fixing ring 9, when the telescopic tube 2 needs to be disassembled, unscrew the nut 46 and remove the clamping assembly 4, pull the telescopic tube 2 to move the connecting tube 6 inside the sleeve 5 until the connecting tube 6 is detached from the pipe body 1, and the telescopic tube 2 can be removed. This design makes the installation and disassembly between the pipe bodies 1 more convenient and faster, and the telescopic tube 2 can be installed and disassembled without moving the two pipe bodies 1.

[0027] A symmetrically arranged fixed bracket 10 is fixedly connected to the inner side of the connecting pipe 6. Multiple guide plates 11 distributed along the polar axis are fixedly connected to one side of the fixed bracket 10. One fixed bracket 10 is vertically aligned with the first sealing ring 7, and the other fixed bracket 10 is vertically aligned with the second sealing ring 8. Through the fixed bracket 10 and the guide plate 11, when the pipe body 1 drains water, the sewage enters the sleeve 5 through the connecting pipe 6 and then enters another pipe body 1. The guide plate 11 can interfere with the flow direction of the sewage, causing the sewage to flow in a vortex, thereby accelerating the flow speed of the sewage. The design of the fixed bracket 10 can support the first sealing ring 7 and the second sealing ring 8, making the sealing performance of the first sealing ring 7 and the second sealing ring 8 better.

[0028] Workflow: Before use, install the various components of the device. When connecting two pipe bodies 1, first press the two connecting pipes 6 to move them inside the sleeve 5, and cause the fixing ring 9 to retract the telescopic pipe 2. Then, put one of the connecting sleeves 3 on the outside of one of the pipe bodies 1, and insert the connecting pipe 6 and the first sealing ring 7 into the inside of the pipe body 1, so that the outside of the first sealing ring 7 is tightly fitted to the inside of the pipe body 1. Then, pull the telescopic pipe 2 to extend it, and put the connecting sleeve 3 at the other end of the telescopic pipe 2 on the outside of the other pipe body 1, and insert the connecting pipe 6 and the first sealing ring 7 into the inside of the pipe body 1. This completes the initial fixing of the telescopic pipe 2 and the sleeve 5. At this time, the fixing bracket 10, the first sealing ring 7, and the clamping plate 42 are all vertically aligned. The next step is to install the clamping assembly 4. Place the two semi-open rings 41 on the outside of the connecting sleeve 3, and rotate one of the semi-open rings 41 on the hinge 43 to make the two mounting slots 44 fit together. Then, rotate the bolt 45 in the mounting slot 44 to move the bolt 45 to the other mounting slot. Inside plate 44, screw nut 46 onto bolt 45 to ensure tight fit between clamping plate 42, connecting sleeve 3, and pipe body 1, thus completing the installation of telescopic pipe 2. When pipe body 1 drains water, sewage enters sleeve 5 through connecting pipe 6 and then into another pipe body 1. Guide plate 11 can interfere with the flow direction of sewage, causing it to vortex and thus accelerating the flow speed. First sealing ring 7 and second sealing ring 8 can seal sleeve 5 and connecting pipe 6 to prevent sewage from entering telescopic pipe 2. The design of fixed bracket 10 can support first sealing ring 7 and second sealing ring 8, improving their sealing performance. When telescopic pipe 2 needs to be disassembled, unscrew nut 46 and remove clamping assembly 4. Pull telescopic pipe 2 to move connecting pipe 6 inside sleeve 5 until connecting pipe 6 is detached from pipe body 1, then telescopic pipe 2 can be removed. This design makes the installation and disassembly between pipe bodies 1 more convenient and faster, allowing the installation and disassembly of telescopic pipe 2 without moving the two pipe bodies 1.
