[0005] The utility model provides a pipeline filter structure that can be quickly replaced, comprising an equipment pipeline and a filter component, wherein a groove is provided on the equipment pipeline, and the filter component is installed at the groove;

[0006] The filter assembly includes an arc-shaped mounting plate and a snap-in plate, the arc-shaped mounting plate is adapted to the slot, the inner surface of the arc-shaped mounting plate is connected with a filter plate, and the filter plate is used to be arranged inside the equipment pipeline; the snap-in plate is slidably connected to the inside of the arc-shaped mounting plate and can extend from its side; a positioning slot is provided on the inner surface of the equipment pipeline, and the snap-in plate is snap-connected with the positioning slot; a slide groove is provided on the outer surface of the equipment pipeline, a slider is provided in the slide groove, the slider is connected to the snap-in plate, a connecting plate is also connected to the slider, and the upper end of the connecting plate is provided on the outer side of the arc-shaped mounting plate.

[0007] By adopting the above scheme, the connecting plate is pushed to drive the slider to slide in the slide groove, so that the snap-on plate is slid back into the interior of the arc-shaped mounting plate, and the arc-shaped mounting plate is snapped into the slot. Since the two are compatible, the arc-shaped mounting plate closes the slot. At this time, the filter plate is placed in the equipment pipeline, and then the connecting plate is pushed in the opposite direction to drive the slider to slide in the slide groove, and the snap-on plate is slid out to be inserted into the positioning slot, and the snap-on plate is snapped with the positioning slot to complete the installation of the filter assembly on the equipment pipeline. When it is necessary to clean or replace the filter plate, the connecting plate is pushed to drive the slider to slide, and the snap-on plate is retracted into the interior of the arc-shaped mounting plate to exit the positioning slot, and then the filter assembly is taken out as a whole, and the filter plate is cleaned or replaced; after cleaning or replacement, it can be reinstalled on the equipment pipeline in the above-mentioned way of installing the filter assembly. The utility model realizes the convenient cleaning and replacement of the filter plate in the water pipe during use, without the need to disassemble the flange connected to the pipeline, and the replacement method is simple, saving time and effort.

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0040] Example 1

[0041] like Figure 1-Figure 4 As shown, this embodiment provides a quickly replaceable pipeline filter structure, including a device pipeline 1 and a filter assembly 2, wherein one end of the device pipeline 1 is connected to the device. The device pipeline 1 is provided with a slot, and the filter assembly 2 is installed at the slot.

[0042] The filter assembly 2 includes an arc-shaped mounting plate 201 and a snap-on plate 203. The arc-shaped mounting plate 201 is adapted to the shape of the slot, and the arc-shaped mounting plate 201 is snap-fitted with the snap-on slot. The arc-shaped mounting plate 201 can be snapped into the slot to close the slot. A filter plate 202 is fixedly connected to the inner surface of the arc-shaped mounting plate 201, and the filter plate 202 is arranged inside the equipment pipeline 1.

[0043] The equipment pipeline 1 is provided with positioning grooves 3 on the inner surfaces of both sides of the groove.

[0044] The snap-in plates 203 are provided in two groups, and the two groups of snap-in plates 203 are provided on both sides of the inside of the arc-shaped mounting plate 201, and can extend from both sides of the arc-shaped mounting plate 201 respectively. The two groups of snap-in plates 203 are slidably matched with the arc-shaped mounting plate 201, and the snap-in plates 203 are snap-fitted with the corresponding positioning slots 3.

[0045] Slide grooves 205 are respectively provided on both sides of the outer surface of the arc-shaped mounting plate 201 , and sliders 206 are fixedly connected to one side of the two sets of the clamping plates 203 . The sliders 206 are arranged in the corresponding slide grooves 205 and slidably cooperate therewith.

[0046] Multiple groups of compression springs 207 are installed between the two groups of sliders 206. The compression springs 207 are arranged inside the arc-shaped mounting plate 201. The upper surfaces of the two groups of sliders 206 are respectively fixedly connected with connecting plates 204. One end of the connecting plate 204 is arranged on the outside of the arc-shaped mounting plate 201.

[0047] The inner wall of the arc-shaped mounting plate 201 and its surroundings are connected to the slot with rubber sealing pads. This arrangement ensures the sealing of the slot connection after the slot is engaged with the arc-shaped mounting plate 201, thereby avoiding leakage at the slot.

[0048] When it is necessary to clean or replace the filter plate 202 inside the equipment pipeline 1, the two groups of connecting plates 204 are squeezed inward (so that the two groups of connecting plates 204 move toward each other), so that the compression spring 207 is deformed, thereby driving the two groups of snap-on plates 203 to slide and move them out of the corresponding positioning slots 3, and then the arc-shaped mounting plate 201 snap-fitted and installed in the slot is taken out. In this way, the filter plate 202 can be cleaned or replaced. After cleaning or replacement, the two groups of connecting plates 204 are squeezed inward. When the arc-shaped mounting plate 201 is snap-fitted with the slot, the connecting plate 204 is released. Under the action of the compression spring 207, the snap-on plate 203 is pushed so that the snap-on plate 203 is snap-fitted with the positioning slot 3.

[0049] The clamping plate 203 is clamped and matched with the positioning slot 3 to ensure that the filter plate 202 has good stability during use and is not easy to fall off, thereby completing the installation of the filter plate 202.

[0050] The utility model realizes convenient removal and reinstallation of the filter plate 202 by sliding the clamping plate 203 relative to the arc-shaped mounting plate 201, clamping in or out of the positioning clamping slot 3, and can realize rapid cleaning and replacement of the filter. After loosening the connecting plate 204, the clamping plate 203 is stably clamped into the positioning clamping slot 3 by utilizing the elastic force generated on both ends by the compression spring 207 after compression due to its recovery deformation, and the clamping plate 203 is positioned, which has a simple structure and is easy to operate.

[0051] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
