DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] PVC pipes are a material whose main component is polyvinyl chloride, and other components are added to enhance its corrosion resistance, heat resistance, toughness and ductility. Since PVC pipes have good corrosion resistance, they are widely used in sewage discharge systems. Therefore, PVC sewage pipe connectors are needed. Before use, it is necessary to confirm that the size of the connector matches the size of the pipe to avoid leakage or loose connection caused by size mismatch. During the installation process, ensure that the sealing between the connector and the pipe is good to prevent water leakage and sewage leakage. During use, it is necessary to check the status of the connector regularly to ensure that there is no looseness, wear or damage.

[0020] like Figure 1 - Figure 3 As shown, the utility model provides a technical solution: a PVC sewage pipe connector, including a filtering device 1, the filtering device 1 includes a filtering box 101, slots are provided on both sides of the top of the filtering box 101, and filter plates 102 are slidably connected in the slots, through holes are provided on both sides of the filtering box 101, and a water outlet pipe 103 is fixedly connected in the through holes, connecting devices 2 are provided on both sides of the filtering device 1, the connecting device 2 includes a fixed pipe 201, the outer wall of the fixed pipe 201 slides on the inner wall of the water outlet pipe 103, and the outer wall of the fixed pipe 201 is provided with a second fixing ring 202.

[0021] It should be noted that during use, the sewage first enters the filter box 101, and the filter plate 102 is filtered. Then the sewage pipe is connected to the outlet pipe 103 through the fixed pipe 201 of the connecting device 2 and fixed by the second fixed ring 202. The filter box 101 and the filter plate 102 can effectively filter solid particles and ensure the cleanliness of the discharged liquid. The installation and disassembly are relatively convenient, and the maintenance work is relatively simple.

[0022] like Figure 2 As shown, a through hole is opened in the center of the top of the filter box 101, and a water inlet pipe 104 is fixedly connected in the through hole. A first fixing ring 105 is slidably connected to the outer wall of the water inlet pipe 104. A through hole is opened on one side of the first fixing ring 105, and a screw rod 106 is rotatably connected in the through hole. A first torsion ring 107 is rotatably connected to one end of the screw rod 106.

[0023] It should be noted that during use, the water inlet pipe 104 and the sewage discharge pipe are first fitted together, and the first twist ring 107 is manually twisted to clamp the pipe with the first fixing ring 105 under the action of the screw 106. Then the sewage enters the filter box 101 through the water inlet pipe 104, and the filter plate 102 is filtered. After the sewage is filtered, it is discharged through the outlet pipe 103. The setting of the filter plate 102 of the filter device 1 makes cleaning and maintenance more convenient. The filter plate 102 can be cleaned or replaced regularly to keep the filtering effect stable.

[0024] like Figure 3 As shown, a through hole is opened on one side of the second fixing ring 202, and a bolt 203 is installed in the through hole. A sewage pipe body 204 is arranged on the inner wall of the fixing pipe 201, and a rack 205 is arranged on the outer wall of the sewage pipe body 204. One end of the rack 205 is connected to the filter box 101, and the other end is slidably connected to a fixing block 206. A latch 207 is arranged on the top of the fixing block 206, and a connecting ring 208 is fixedly connected to the bottom of the fixing block 206. A threaded groove 209 is fixedly connected to one side of the connecting ring 208, and a second torsion ring 210 is rotatably connected to the outer wall of the threaded groove 209. The sewage pipe body 204, the connecting ring 208 and the second torsion ring 210 are on the same axis.

[0025] It should be noted that during use, the sewage pipe body 204 is first placed in the fixed pipe 201, and then the bolt 203 is manually twisted to drive the second fixed ring 202 to tighten the sewage pipe body 204, and the connecting ring 208 is manually moved. In this process, the rack 205 slides to a suitable position on the inner wall of the fixed block 206 and is fixed by the pin 207. Finally, the second twist ring 210 is manually twisted to fix the sewage pipe body 204 through the threaded groove 209. This device can ensure the stability of the connecting parts and reduce the risk of falling off and leakage caused by vibration or external force.

[0026] During use, the water inlet pipe 104 and the sewage discharge pipe are first fitted together, and the pipes are clamped by the first fixing ring 105. The sewage enters the filter box 101 through the water inlet pipe 104, and is filtered by the filter plate 102. The filtered sewage is discharged through the outlet pipe 103, and the fixed pipe 201 is placed in the outlet pipe 103. Then, the sewage pipe body 204 is fastened by the second fixing ring 202. The rack 205 slides to a suitable position on the inner wall of the fixing block 206 and is fixed by the pin 207. Finally, the second twist ring 210 is manually twisted to fasten the sewage pipe body 204 through the threaded groove 209. This device can ensure the stability of the connector and reduce the risk of falling off and leakage due to vibration or external force.
