Furthermore, the sealing ring 23 embedded on the outer bottom of the connecting bracket 22 solves the problem of inconvenient filter element replacement in existing oil filter assemblies, which leads to insufficient cleaning of residual debris during maintenance and repairs, thus preventing automatic transmission malfunctions during use.
[0022] Example 2: To achieve more precise positioning and stable force transmission when connecting the main body and the sealing assembly, such as Figure 2 and Figure 3 As shown, in this embodiment, a positioning ring 211 is fixedly installed in the middle of the top of the housing 21, and the inner diameter of the positioning ring 211 matches the outer diameter of the top block 331.
[0023] Specifically, a positioning ring 211 is fixedly installed in the middle of the top of the housing 21, and the inner diameter of the positioning ring 211 matches the outer diameter of the top block 331 to achieve precise positioning of the top block 331, ensuring that the force of the adjusting screw 33 can be accurately transmitted when the main body 2 is connected to the sealing assembly 1, thus ensuring connection stability.
[0024] Furthermore, a sealing ring 23 is installed by slotting the outer side of the bottom of the connecting frame 22. The outer wall of the sealing ring 23 is in clearance fit with the inner wall of the housing 21, and the inner wall of the sealing ring 23 is in clearance fit with the outer wall of the connecting frame 22.
[0025] Specifically, a groove is cut on the outer side of the bottom of the connecting bracket 22 and a sealing ring 23 is embedded therein. The outer wall of the sealing ring 23 is fitted with the inner wall of the housing 21 with a clearance fit, and the inner wall is fitted with the outer wall of the connecting bracket 22 with a clearance fit, so as to achieve a good sealing effect, prevent oil from leaking from the inside of the main body 2, and ensure the integrity and filtration effect of the oil filtration path.
[0026] Furthermore, the top block 331 is movably mounted directly above the positioning ring 211, and the bottom of the top block 331 is provided with anti-slip texture.
[0027] Specifically, the top block 331 is movably installed directly above the positioning ring 211, and the bottom of the top block 331 is provided with anti-slip texture to increase the friction when the top block 331 contacts the housing 21, prevent the top block 331 from sliding during the adjustment process of the adjusting screw 33, and improve the adjustment accuracy and connection reliability.
[0028] Example 3: In order to allow the engine oil to enter the main body for filtration in an orderly manner and to provide a stable installation base for the connecting frame, such as Figure 1 and Figure 2 As shown, in this embodiment, the bottom front of the bottom cover 11 is provided with a liquid inlet channel 122, and the inner side of the bottom cover 11 at the liquid inlet channel 122 is connected to and installed with an internal threaded sleeve 121. The bottom of the inner wall of the bottom cover 11 outside the internal threaded sleeve 121 is provided with an internal thread 111 for the installation of the connecting bracket 22.
[0029] Specifically, an inlet channel 122 is provided at the bottom front of the bottom cover 11, and an internally threaded sleeve 121 is installed inside the bottom cover 11 at the inlet channel 122. At the same time, an internal thread 111 for installing the connecting bracket 22 is provided at the bottom of the inner wall of the bottom cover 11 outside the internally threaded sleeve 121, so as to facilitate the oil to enter the body 2 for filtration and provide a stable structural foundation for the installation of the connecting bracket 22.
[0030] Furthermore, an inlet pipe 13 is connected and installed inside the inlet channel 122, and an outlet channel 123 is provided on the front of the bottom cover 11 above the inlet channel 122, with an outlet pipe 14 connected and installed inside the outlet channel 123.

[0032] In use, the connecting bracket 22 is threaded onto the bottom cover 11. The filter element is then movably inserted into the inner side of the housing 21. The connecting bracket 22 is then movably secured to the bottom inner side of the housing 21 via the bottom sealing ring 23, ensuring a good clearance fit between the outer wall of the sealing ring 23 and the inner wall of the housing 21, and between the inner wall of the sealing ring 23 and the outer wall of the connecting bracket 22, thus achieving a sealing effect.
[0033] Ensure the adjusting screw 33 of the positioning assembly 3 is in the correct position, place the positioning frame 31 in the predetermined installation position, aligning the grooves on both sides of the bottom of the limiting frame 12 with the bottom of the positioning frame 31 and clamping them in place. Align the bottom of the housing 21 of the main body 2 with the bottom cover 11 of the sealing assembly 1, and connect them via the positioning assembly 3. At this time, the top block 331 at the bottom of the adjusting screw 33 should be directly above the positioning ring 211, and the outer diameter of the top block 331 should match the inner diameter of the positioning ring 211. Rotate the adjusting screw 33 to adjust the height of the top block 331, ensuring a tight connection between the main body 2 and the sealing assembly 1. The anti-slip texture on the bottom of the top block 331 increases the friction when in contact with the housing 21, preventing slippage.
[0034] Engine oil flows into the inlet channel 122 from the inlet pipe 13, enters the main body 2 through the internal threaded sleeve 121 inside the bottom cover 11, and after being filtered by the filter element, the clean engine oil flows out from the outlet channel 123 through the outlet pipe 14, completing the engine oil filtration process. When replacing the filter element, rotate the adjusting screw 33 in the reverse direction to raise the top block 331, releasing the tight connection between the main body 2 and the sealing assembly 1. Separate the main body 2 from the sealing assembly 1, thereby removing the old filter element from the inside of the housing 21 above the connecting bracket 22. Clean any remaining debris and impurities from inside the housing 21 and on the connecting bracket 22. Then install the new filter element, repeating the above filter element installation and main body to sealing assembly connection steps to complete the filter element replacement.
