[0006] Preferably, the limiting fixing component includes a limiting plate, a baffle plate and a chuck, the limiting plate is fixedly sleeved on the top end of the intermediate tube, the baffle plate is fixedly sleeved on the top end of the filter cartridge, the baffle plate is clamped on the limiting plate, and a fastener is provided on the limiting plate, and the fastener presses the chuck, the limiting plate and the baffle plate.

[0007] Preferably, the fastener includes a bolt and a nut, and the limit plate, baffle plate and chuck are all provided with limit grooves. The bottom end of the bolt is rotated on the limit groove of the limit plate through an axis, and the top of the bolt is clamped on the limit plate of the baffle plate and the chuck. The nut is threadedly connected to the bolt and the bottom is pressed on the chuck.

[0008] Preferably, the limiting groove is a U-shaped structure.

[0009] Preferably, the groove is arranged to match the interior of the pipe.

[0010] Preferably, a sealing cap is threadedly connected to the bottom end of the intermediate tube.

[0011] The utility model adopts the above structure to achieve the following beneficial effects: the limiting fixing part limits the slot direction of the filter cartridge, water enters from the pipeline and enters the filter cartridge through the slot, impurities in the water are filtered and precipitated in the filter cartridge, and the filtered water flows from the filter cartridge into the pipeline for continued transportation. After long-term use, the limiting fixing part can be removed, and the filter cartridge can be pulled out of the middle pipe for cleaning to avoid clogging of the filter cartridge.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-4As shown, a pipeline filtering device proposed by the utility model includes a pipeline 1, an intermediate pipe 2 and a filter cartridge 3, the intermediate pipe 2 is connected to the middle part of the pipeline 1, and the bottom end of the intermediate pipe 2 is threadedly connected with a blocking cap 13, the filter cartridge 3 is inserted into the intermediate pipe 2, and the side wall of the filter cartridge 3 is provided with a groove 4, and the groove 4 is matched with the interior of the pipeline 1 to facilitate the entry of debris in the water into the filter cartridge 3 from the groove 4, and a limiting fixture 5 is provided between the intermediate pipe 2 and the top of the filter cartridge 3, and the limiting fixture 5 limits the direction of the groove 4 of the filter cartridge 3, water enters from the pipeline 1 and enters the filter cartridge 3 through the groove 4, and the debris in the water is filtered and precipitated in the filter cartridge 3, and the filtered water flows from the filter cartridge 3 into the pipeline 1 for continued transportation. After long-term use, the limiting fixture 5 can be removed, and the filter cartridge 3 can be pulled out of the intermediate pipe 2 for cleaning to avoid clogging of the filter cartridge 3.

[0020] The limiting fixing member 5 includes a limiting plate 6, a baffle plate 7 and a chuck 8. The limiting plate 6 is fixedly sleeved on the top end of the intermediate tube 2.
