DETAILED DESCRIPTION

[0022] The following will be combined with 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 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.

[0023] Example 1

[0024] like Figure 1 to Figure 4 As shown, this embodiment proposes a fuel filter for automobile, including a shell 1 and a fixing seat 3, the outer peripheral surface of the shell 1 is fixedly connected with a connecting seat 2 by screws, the interior of the connecting seat 2 is slidably equipped with a movable block 6, the movable block 6 has two symmetrically arranged support rods 7 on the movable hinge, the two support rods 7 have guide rods 8 on the movable hinge, one side of the two guide rods 8 is fixedly connected with a clamping block 10 by screws, one side of the movable block 6 is fixedly connected with a retreat block 4 by screws, the retreat block 4 is slidably assembled in the interior of the connecting seat 2, and one side of the shell 1 is connected to an oil inlet pipe 1 3. The other side of the housing 1 is connected with an oil outlet pipe 14. Through the arrangement of the block 10 and the guide rod 8 and other structures, the bottom of the connecting seat 2 is aligned with the installation groove 19 opened in the fixing seat 3 and inserted into it during installation. When the two blocks 10 slidingly arranged inside the connecting seat 2 move to one side of the slot 12 opened inside the installation groove 19, the first spring 9 will eject the block 10 into the slot 12. At this time, the fixation is completed. When disassembling, the retreat rod is pressed downward, and the retreat rod pulls the movable block 6 to pull the guide rod 8 and the block 10 together to complete the disassembly, thereby achieving the effect of convenient disassembly.

[0025] like Figure 1 to Figure 4 As shown, a filter screen 17 is provided inside the housing 1, a straight rod 15 is rotatably installed inside the housing 1, and a plurality of filter plates 16 evenly distributed in a circumference are provided on the outer circumferential surface of the straight rod 15. Through the arrangement of the filter screen 17 and the filter plates 16 and other structures, the fuel is filtered for the first time through the filter screen 17, and the filtered fuel is filtered for the second time through the filter plates 16, thereby improving the cleanliness of the fuel.

[0026] like Figure 1 to Figure 4As shown, a groove 18 is provided inside the connecting seat 2, and the movable block 6 is slidably connected inside the groove 18. The bottom wall of the groove 18 and the bottom of the movable block 6 are commonly connected with a second spring 11. A mounting groove 19 is provided on the top of the fixed seat 3, and two symmetrically arranged card grooves 12 are provided inside the mounting groove 19. The card block 10 is slidably connected inside the card groove 12. Movable grooves are provided on both sides of the connecting seat 2. The outside of the guide rod 8 is sleeved with a first spring 9, one end of the first spring 9 is welded to one side of the card block 10, and the other end of the first spring 9 is welded to the side wall of the movable groove. A retreat groove 5 is provided on one side of the connecting seat 2, and the retreat block 4 is slidably connected inside the retreat groove 5.

[0027] In this embodiment, when the filter needs to be replaced and disassembled, the retreat block 4 is pressed downward. Since the retreat rod is fixedly connected to the movable block 6, the movable block 6 will be driven downward together when the retreat rod is pressed downward. Since the movable block 6 is internally hinged with two support rods 7, the two support rods 7 will move with the downward movement of the movable block 6. Since the other ends of the two support rods 7 are movably hinged with the guide rod 8, the guide rod 8 is pulled due to the movement of the support rod 7. Since the other end of the guide rod 8 is fixed on the clamping block 10, the guide rod 8 will be driven to move together with the clamping block 10 when it is pulled by the support rod 7. The clamping block 10 will be pulled out of the clamping slot 12. At this time, the limiting effect between the connecting seat 2 and the fixed seat 3 is lost, and the disassembly can be completed.

[0028] Furthermore, when installing a new filter, the operator aligns the bottom of the connection seat 2 of the filter with the installation groove 19 opened inside the fixing seat 3 and inserts it. Because one side of the card block 10 is inclined, the two symmetrically arranged card blocks 10 slidingly arranged inside the connection block will move toward the inside of the movable groove when being squeezed by the installation groove 19. At this time, the first spring 9 will be compressed, thereby deforming and storing energy. When the card block 10 moves to the card slot 12 opened in the installation groove 19 and is completely aligned, the first spring 9 loses external force and releases energy, ejecting the card block 10 into the inside of the card slot 12. At this time, the fixation is completed. The quick disassembly makes the replacement of the device more convenient, saving time and labor.

[0029] Furthermore, when the fuel enters the housing 1 through the fuel inlet pipe 13, it is first screened by the filter 17 to filter out large impurities. After the first filtration, the fuel passes through the filter plate 16 to drive the filter plate 16 to rotate while filtering out fine impurities. After the second filtration, the fuel is discharged from the fuel outlet pipe 14 to ensure the cleanliness of the fuel.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. 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.
