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.

[0032] Reference Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: a pipeline filter, comprising a tube body 1 and a filter body 2, the number of tube bodies 1 is set to two, and the distance between the two tube bodies 1 is greater than the length of the filter body 2, the left and right ends of the filter body 2 are connected by a fixing mechanism 3, the fixing mechanism 3 comprises a connecting block 31, the shape of the connecting block 31 is annular, the inner wall of the connecting block 31 is fixedly connected to the outer wall of the filter body 2, the outer wall of the connecting block 31 is slidably connected with a connecting ring 32, the sliding direction of the connecting ring 32 is left and right sliding, the end of the connecting ring 32 away from the tube body 1 is provided with a baffle with a diameter smaller than the outer diameter of the connecting block 31, the outer wall of the connecting ring 32 is slidably connected with a slide plate 33, the sliding direction of the slide plate 33 is left and right sliding, and the inner wall of the connecting ring 32 is penetrated and slidably connected with an extrusion block 34.

[0033] Reference Figure 2 , Figure 4 and Figure 5 The end of the extrusion block 34 close to the tube body 1 is fixedly connected with the airbag 2 312, and the inner wall of the extrusion block 34 is provided with an air pressure chamber 35. The interior of the airbag 2 312 is connected with the interior of the air pressure chamber 35. The material of the airbag 2 312 is set to rubber. The inner wall piston of the air pressure chamber 35 is connected with a slider 36. The moving direction of the slider 36 is left and right. The end of the slider 36 close to the tube body 1 is fixedly connected with a block 37. The left end of the block 37 is provided with a serrated groove. The inner wall of the extrusion block 34 is provided with a slot 38. The shape of the slot 38 is serrated, and the shape of the slot 38 matches the shape of the block 37. Through the matching shape setting, it is ensured that when the block 37 moves, it can just enter the slot 38, thereby achieving a limiting effect.

[0034] Reference Figure 2 , Figure 4 and Figure 5 The end of the extrusion block 34 away from the tube body 1 is fixedly connected to a slide rod 39, and a slide groove 310 is opened on the inner wall of the connecting ring 32. The slide rod 39 is inside the slide groove 310. The shape of the slide groove 310 is an arc shape, and the width of the slide groove 310 matches the diameter of the slide rod 39. The end of the slider 36 away from the tube body 1 is fixedly connected to a pull rope 311, and the pull rope 311 is inelastic. The end of the pull rope 311 away from the slider 36 is fixedly connected to the outer wall of the slide plate 33, and the pull rope 311 passes through the inner wall of the slide rod 39. The setting of the pull rope 311 passing through the slide rod 39 ensures that the position of the pull rope 311 can be limited, and the end of the slide rod 39 away from the tube body 1 is slidably connected to the end of the slide plate 33 close to the tube body 1.

[0035] Reference Figure 2 , Figure 3 and Figure 5The filter body 2 is provided with an extension assembly 4 inside, and the extension assembly 4 includes a mounting groove 41, and the inner wall of the mounting groove 41 is rotatably connected with a screw 42, and the inner wall of the filter body 2 is slidably connected with an extension tube 43, and the inner wall diameter of the extension tube 43 is smaller than the diameter of the inner wall of the filter body 2, and the end of the extension tube 43 away from the end of the tube body 1 is provided with an inclined surface, and the setting of the inclined surface ensures that impurities will not accumulate in the dead angle between the extension tube 43 and the filter body 2, and the end of the extension tube 43 close to the tube body 1 is fixedly connected with a contact plate 44, and the contact plate 44 is used to contact with the outer wall of the tube body 1, and the end of the contact plate 44 close to the tube body 1 An air bag 45 is fixedly connected, and the setting of the air bag 45 ensures that the contact plate 44 and the tube body 1 can fit together, thereby achieving the effect of preventing water leakage. The right end of the extension tube 43 is fixedly connected to a connecting rod 46, the inner wall of the connecting rod 46 passes through and is threadedly connected to the outer wall of the screw 42, and the end of the screw 42 away from the tube body 1 is fixedly connected to a bevel gear 1 47, and the inner wall of the filter body 2 passes through and is rotatably connected to a rotating rod 48, the outer wall of the rotating rod 48 is fixedly connected to a bevel gear 2 49, the bevel gear 1 47 is meshed with the bevel gear 2 49, and the outer wall of the rotating rod 48 at the end outside the filter body 2 is fixedly connected to a rotating block 410.

[0036] Working principle: When in use, the staff first places the filter body 2 between the two tube bodies 1. At this time, since the length of the filter body 2 is shorter than the length between the two tube bodies 1, the staff can easily place it successfully.

[0037] After the placement is completed, the staff pulls the connecting ring 32 toward the end close to the tube body 1. After pulling, the staff rotates the connecting ring 32 and the slide plate 33, so that the slide bar 39 is at the same horizontal position as the slide groove 310 from the outer circle to the inner circle, so that the slide bar 39 moves toward the direction close to the tube body 1, thereby causing the extrusion block 34 to move toward the direction close to the tube body 1.

[0038] When the airbag 2 312 moves to the point where it contacts the outer wall of the tube body 1, since the inner wall of the airbag 2 312 has a force that maintains the shape of the airbag 2 312, the airbag 2 312 can drive the connecting ring 32 to move to a position that is exactly coaxial with the tube body 1. When the tube body 1 is coaxial with the connecting ring 32, the connecting ring 32 and the slide plate 33 continue to rotate. At this time, the airbag 2 312 is squeezed, causing the gas inside the airbag 2 312 to enter the air pressure chamber 35, so that the slider 36 drives the block 37 to move in the direction close to the slot 38 under the push of the gas, so that the block 37 is limited by the slot 38 and cannot move. At the same time, because of the friction between the tube body 1 and the airbag 2 312, the connecting ring 32 cannot move horizontally.

[0039] At this time, the staff rotates the rotating block 410, so that the rotating block 410 drives the rotating rod 48 and the bevel gear 2 49 to rotate, so that the bevel gear 1 47 rotates under the drive of the bevel gear 2 49, so that the screw 42 rotates, thereby driving the connecting rod 46 to move toward the direction close to the tube body 1, thereby making the extension tube 43 move toward the direction close to the tube body 1, and driving the contact plate 44 to move toward the direction close to the tube body 1.

[0040] When the contact plate 44 approaches the tube body 1, the airbag 45 first contacts the tube body 1 and is deformed after being squeezed by the tube body 1, thereby filling the gap between the contact plate 44 and the tube body 1, thereby ensuring that liquid leakage is not likely to occur between the tube body 1 and the extension tube 43.

[0041] When the equipment needs to be disassembled, the staff pushes the slide plate 33 in the direction away from the tube body 1, so that the slide plate 33 drives the pull rope 311 to move in the direction away from the tube body 1, thereby causing the pull rope 311 to pull the slider 36 in the direction away from the tube body 1, thereby causing the block 37 to leave the slot 38.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
