Description

Technical Field

[0001] The utility model relates to the technical field of motor oil filters, and particularly relates to a convenient replaceable engine oil filter assembly. Background Technique

[0002] Each component in the engine achieves normal operation through the lubrication of engine oil. However, metal debris generated during the operation of the components, dust entering, carbon deposits oxidized at high temperatures, and some water vapor will continuously mix into the engine oil. Over time, the service life of the engine oil will be reduced, and in severe cases, it may affect the normal operation of the engine. Therefore, the role of the engine oil filter is reflected at this time. Simply put, the main role of the engine oil filter is to filter out most of the impurities in the engine oil, keep the engine oil clean, and extend its normal service life;

[0003] Currently, the filter element of the filter is often fixed in the filter housing through a complex structure, which requires users to use professional tools and follow cumbersome operation steps when replacing the filter element. This complex installation method not only increases the difficulty and time cost of replacing the filter element, but also may cause problems such as damage to the filter element or poor sealing of the filter housing due to improper operation. Therefore, we propose a convenient replaceable engine oil filter assembly to solve the above problems. Content of the Utility Model

[0023] Example

[0024] like Figures 1-4As shown in the figure, a convenient replaceable oil filter assembly proposed by an embodiment of the present utility model includes a filter body 1. An inner ring 2 is fixedly connected to the inner wall of the filter body 1. Two limiting grooves 3 with one side open are formed on the inner ring 2. A filter element 4 is in movable contact with the filter body 1. A limiting block 5 is in movable contact with the limiting groove 3. The limiting block 5 is fixedly connected to the filter element 4. An outer ring 7 is fixedly connected to the filter body 1. A plurality of grooves 8 are annularly formed at the top of the outer ring 7. A clamping groove 9 is formed on the inner wall of one side of the groove 8. A top cover 10 is in movable contact with the top of the filter body 1. A plurality of U-shaped blocks 12 are fixedly connected to the bottom of the top cover 10 in an annular shape. A positioning rod 13 is welded between the inner walls on both sides of the U-shaped block 12. A connecting rod 14 is slidably connected to the positioning rod 13. A clamping pin 15 is welded to one side of the connecting rod 14. The clamping pin 15 is clamped with the corresponding clamping groove 9. A spring 16 is welded between the other side of the connecting rod 14 and the inner wall of one side of the corresponding U-shaped block 12. A fixed pulley 17 is rotatably connected to one side of the U-shaped block 12. A flexible steel cable 18 is fixedly connected to one side of the connecting rod 14. The end of the flexible steel cable 18 bypasses one side of the corresponding fixed pulley 17 and extends above the top cover 10 and is fixedly connected to a moving ring 19. Moving the moving ring 19 upward drives the connecting rod 14 to move through the flexible steel cable 18. The connecting rod 14 slides on the positioning rod 13 and compresses the spring 16. The connecting rod 14 drives the corresponding clamping pin 15 to be separated from the clamping groove 9. Move the top cover 10 to separate the top cover 10 from the filter body 1. When removing the filter element 4, during installation, align the limiting block 5 on the filter element 4 with the limiting groove 3 and place it. Move the moving ring 19 upward to drive the connecting rod 14 to move through the flexible steel cable 18. The connecting rod 14 slides on the positioning rod 13 and compresses the spring 16. The connecting rod 14 drives the clamping pin 15 to move. Then insert the limiting post 11 on the top cover 10 into the corresponding clamping groove 6. At this time, release the force on the moving ring 19. The spring 16 in the compressed state resets. The spring 16 drives the corresponding connecting rod 14 to move. The connecting rod 14 drives the clamping pin 15 to move, so that the clamping pin 15 is clamped with the corresponding clamping groove 9 to fix the top cover 10. Therefore, professional tools are not required during the disassembly and assembly process, which is convenient for quickly replacing the filter element 4.

[0025] In some embodiments, the spring 16 is movably sleeved on the corresponding positioning rod 13. The connecting rod 14 is in movable contact with the corresponding groove 8. The setting of the spring 16 plays a role in resetting.

[0026] In some embodiments, a column 20 is connected and fixed to the top of the top cover 10.

[0027] In some embodiments, a clamping groove 6 is formed at the top of the limiting block 5. A limiting post 11 is in movable contact with the clamping groove 6. The bottom end of the limiting post 11 is fixedly connected to the inner wall of the top of the top cover 10. The setting of the limiting post 11 plays a role in limiting.

[0028] In some embodiments, a guiding hole is formed in the connecting rod 14. The connecting rod 14 is slidably connected to the corresponding positioning rod 13 through the guiding hole. The setting of the positioning rod 13 plays a positioning role.

[0029] In some embodiments, four through holes are formed in the top cover 10. The top cover 10 is slidably connected to the corresponding flexible steel cable 18 through the through holes. The setting of the flexible steel cable 18 plays a connecting role.

[0030] Working principle or structural principle: During use, when disassembling, move the moving ring 19 upward. The moving ring 19 drives the corresponding connecting rod 14 to move through the flexible steel cable 18. The connecting rod 14 slides on the corresponding positioning rod 13 and compresses the spring 16. At the same time, the connecting rod 14 drives the corresponding pin 15 to separate from the clamping groove 9. Then move the top cover 10. The top cover 10 drives the limiting post 11 to separate from the corresponding clamping groove 6, so that the top cover 10 is separated from the filter body 1. When moving the filter element 4, the filter element 4 drives the limiting block 5 to separate from the limiting groove 3, and then it can be removed. During installation, align the limiting block 5 on the filter element 4 with the limiting groove 3 and place it. Then move the moving ring 19 upward. The moving ring 19 drives the corresponding connecting rod 14 to move through the flexible steel cable 18. The connecting rod 14 slides on the corresponding positioning rod 13 and compresses the spring 16. At the same time, the connecting rod 14 drives the corresponding pin 15 to move. Then insert the limiting post 11 on the top cover 10 into the corresponding clamping groove 6. At this time, release the force on the moving ring 19. The spring 16 in the compressed state resets. Under the action of its own elastic force, the spring 16 drives the corresponding connecting rod 14 to move. The connecting rod 14 drives the corresponding pin 15 to move, so that the pin 15 is clamped with the corresponding clamping groove 9 to fix the top cover 10. Therefore, no professional tools are required during the disassembly and assembly process, which is convenient for quickly replacing the filter element 4.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
