[0029] An oil filter mechanism, which is disposed inside the cavity 9 and is used to filter the oil;

[0030] The oil filtering mechanism includes an end cover 18 and a limit block 12, which are arranged in parallel. A fixing sleeve 7 is fixedly connected to one side of the end cover 18, and a plurality of annular grooves 21 are provided on one side of the limit block 12. A filter cartridge 8 is fixedly connected to the inside of the annular groove 21. A card slot 27 is provided at one end of the fixing sleeve 7. One end of the filter cartridge 8 located in the outermost layer is fixedly connected to the inside of the card slot 27. When the filter cartridge 8 of the inner layer gradually becomes blocked, the internal pressure of the filter cartridge 8 increases, and the oil pushes the sliding plate 20 to move laterally. The sliding plate 20 squeezes the spring 13. At this time, the sliding plate 20 drives a plurality of convex plates 24 on one side to move. At this time, the innermost convex plate 24 is separated from the innermost filter cartridge 8, and the filter cartridge 8 of the second layer will not be separated from the convex plate 24. At this time, the filter cartridge 8 of the second layer can be used for filtering. If the second layer is blocked, the sliding plate 20 continues to move forward, and so on and so forth until the last layer of the filter cartridge 8 is blocked.

[0031] In the utility model, the inner wall of the first through hole 15 is slidably connected with a sliding bar 23, one end of the sliding bar 23 is fixedly connected with a blocking block 16, one end of the blocking block 16 is fixedly connected with a round rod 14, the blocking block 16 is used in conjunction with the second through hole 25, one end of the round rod 14 is fixedly connected with a sliding plate 20, the fixed sleeve 7 is used in conjunction with the sliding plate 20, a groove 19 is provided on one side of the fixed sleeve 7 close to the end cover 18, and the same spring 13 is fixedly connected between one side of the end cover 18 and one side of the sliding plate 20.

[0032] In particular, a plurality of convex plates 24 are fixedly connected to one side of the sliding plate 20 , and the plurality of convex plates 24 respectively contact one end of the plurality of filter cartridges 8 .

[0033] In particular, two symmetrically arranged positioning rods 17 are fixedly connected to one side of the end cover 18 , and two symmetrically arranged positioning grooves 11 are opened on the inner wall of one side of the cavity 9 , and the positioning grooves 11 and the positioning rods 17 are used in coordination.

[0034] In particular, the lengths of the plurality of filter cartridges 8 are different and gradually increase from the inside to the outside.

[0035] In particular, a third oil inlet 22 is provided inside the limiting block 12 , and the third oil inlet 22 is used in conjunction with the first oil inlet 2 .

[0036] In particular, the heights of the plurality of convex plates 24 are different, so as to facilitate matching with the plurality of filter cartridges 8 .

[0037] Working principle: When oil is fed in, the oil enters the interior of the third oil inlet 22 through the first oil inlet 2, and after being filtered by multiple filter cartridges 8, it can enter the interior of the cavity 9, and then be discharged into the interior of the arc groove 6 through the second oil inlet 10 and the oil outlet 5, and finally be discharged through the oil outlet 4, completing the oil feeding process;

[0038] When the inner filter cartridge 8 gradually becomes clogged, the internal pressure of the filter cartridge 8 increases, the oil pushes the sliding plate 20 to move horizontally, and the sliding plate 20 squeezes the spring 13. At this time, the sliding plate 20 drives multiple convex plates 24 on one side to move. At this time, the innermost convex plate 24 is separated from the innermost filter cartridge 8, and the second layer of the filter cartridge 8 will not be separated from the convex plate 24. At this time, the second layer of the filter cartridge 8 can be used for filtering. If the second layer is clogged, the sliding plate 20 continues to move forward, and so on and so forth until the last layer of the filter cartridge 8 is clogged;

[0039] When filtering is impossible, the sliding plate 20 continues to move, the sliding plate 20 enters the interior of the groove 19, the block 16 moves out from the interior of the second through hole 25, and the oil directly enters the third through hole 26 through the interior of the groove 19, and is directly discharged into the interior of the cavity 9 through the gap between the round rod 14 and the second through hole 25, completing the oil supply process, which can extend the filtering time and reduce the possibility of blockage.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
