However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0027] Please refer to the appendix carefully. Figure 1-7An oil filter end cap assembly with a fault-prevention structure includes a cylindrical body 1, a filter element 2 embedded inside the cylindrical body 1, and an upper mounting ring 3 installed on the top of the filter element 2. The upper mounting ring 3 has first mounting grooves 4 on both sides of its top for assembling an upper end cap 7. Each of the two first mounting grooves 4 has a first quick-release assembly 5 on one side. The first quick-release assembly 5 includes a first fixing groove 501, a first spring 502, and a first locking block 503. Each of the two first mounting grooves 4 has a first fixing groove 501 on one side, and a first spring 502 is fixedly connected to the inner wall of one side of each of the two first fixing grooves 501. Each of the two first springs 502 has a first locking block 503 fixedly connected to one end, and both ends of one side of the two first locking blocks 503 are inclined, so that the first locking blocks 503 can be used to... When the first fixing block 6 contacts, it can be smoothly pushed, and under the action of the first spring 502, it can quickly snap into the first slot 14. The first fixing block 6 is assembled inside the two first mounting slots 4. The top of the first fixing block 6 is fixedly connected to the upper end cover 7. The upper end cover 7 is quickly assembled with the first quick-installation assembly 5 in the first mounting slot 4 through the first fixing block 6. The bottom of the filter element 2 is fixedly installed with a lower mounting ring 16, and the bottom of the lower mounting ring 16 is provided with second mounting slots 8 on both sides for assembling the lower end cover 11. The two second mounting slots 8 are provided with a second quick-installation assembly 9 on one side. The second quick-installation assembly 9 includes a second fixing slot 901, a second spring 902, and a second locking block 903. The two second mounting slots 8 are provided with a second fixing slot 901 on one side, and the two first fixing slots 902 and the second quick-installation assembly 903 are provided with a second locking block 903. The two second mounting slots 8 are provided with a second fixing slot 901 on one side, and the two first fixing slots 902 and the second quick-installation assembly 903 are provided with a second locking block 903. Each of the two fixing slots 901 has a second spring 902 fixedly connected to one side of its inner wall, and each of the two second springs 902 has a second locking block 903 fixedly connected to one end. The two locking blocks 903 are inclined at both ends, allowing them to be smoothly pushed when in contact with the second fixing block 10. Simultaneously, under the action of the second springs 902, they can quickly engage with the second locking slot 15. The two second mounting slots 8 are equipped with second fixing blocks 10. The bottom of the second fixing block 10 is fixedly connected to a lower end cover 11. The lower end cover 11 is quickly assembled with the second quick-release assembly 9 in the second mounting slot 8 via the second fixing block 10. Limiting slots 12 are provided at the top of both the first fixing slot 501 and the second fixing slot 901. The first locking block 503 and the second locking block... Each of the 903 blocks has a fixed limit block 13 at its top, and the limit block 13 is located inside the limit groove 12. The limit block 13 can prevent the first locking block 503 and the second locking block 903 from shifting or falling off during assembly, ensuring the firmness of the assembly. The diameter of the first mounting groove 4 is larger than the diameter of the second mounting groove 8, and the diameter of the first fixing block 6 is also larger than the diameter of the second fixing block 10. The size difference means that the upper end cover 7 and the lower end cover 11 can only be installed in their respective corresponding grooves and cannot be interchanged. This effectively avoids problems such as sealing failure or structural damage caused by misinstallation during assembly, and significantly improves the accuracy and reliability of the assembly. The first fixing block 6 has a first locking groove 14 on both sides, and the shape of the first locking groove 14 matches the first locking block 503.To ensure the first locking block 503 can accurately engage with the first locking slot 14, the second fixing block 10 has second locking slots 15 on both sides. The shape of the second locking slots 15 matches the second locking block 903, ensuring the second locking block 903 can accurately engage with the second locking slot 15.

[0028] The specific operation method of this utility model is as follows:

[0029] During installation, the two first fixing blocks 6 located at the bottom of the upper end cover 7 are aligned with the corresponding first mounting slots 4 and pushed downwards vertically. During this pushing process, the outer wall of the first fixing block 6 contacts the first locking block 503 located inside the first mounting slot 4, applying a lateral pushing force to the first locking block 503, causing it to move to one side and simultaneously compressing the first spring 502 connected to it. When the first slot 14 and the first locking block 503 are at the same horizontal position, the first locking block 503 is engaged inside the first slot 14 under the action of the first spring 502, completing the assembly of the upper end cover 7. After the upper end cover 7 is installed, the two second fixing blocks 1 located at the top of the lower end cover 11 are... The second mounting block 10 is aligned with the corresponding second mounting slot 8 and pushed upwards vertically, similar to the installation process of the upper end cover 7. During the pushing process, the second fixing block 10 contacts the second locking block 903 and pushes it to move laterally, compressing the second spring 902. When the second locking block 903 is aligned with the second locking slot 15, the second spring 902 pushes the second locking block 903 into the second locking slot 15, thus achieving the fixed installation of the lower end cover 11. The first mounting slot 4 and the second mounting slot 8 have different diameters, thereby ensuring that the upper end cover 7 and the lower end cover 11 can only be installed in their respective corresponding slots and cannot be interchanged. This effectively avoids problems such as sealing failure or structural damage caused by misinstallation during assembly, and significantly improves the accuracy and reliability of assembly.
