Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-2 This utility model provides a technical solution: In this technical solution, an embedded installation structure for a sealing ring in an automotive filter housing includes an oil filter 1. An annular groove 2 is provided on the side wall of the oil filter 1. A sealing ring 3 is embedded in the annular groove 2. A pressing mechanism 4 is provided on the outside of the annular groove 2. The pressing mechanism 4 can press the sealing ring 3. The extrusion mechanism 4 includes an installation groove 41, an extrusion ring 42, and a convex ring 43. The installation groove 41 is formed on the upper wall of the oil filter 1. The installation groove 41 is annular and is located on the outside of the annular groove 2. The inner side wall of the installation groove 41 is provided with internal threads. The outer side of the extrusion ring 42 is provided with external threads. The extrusion ring 42 is installed in the installation groove 41 by rotating the threads. The upper end of the extrusion ring 42 is provided with a convex ring 43. The extrusion ring 42 can support the sealing ring 3. In this technical solution, the extrusion ring 42 and the mounting groove 41 are threaded together, and the extrusion force on the sealing ring 3 can be adjusted by rotating the extrusion ring 42, so that the sealing ring 3 fits tightly with the external engine bottom wall, effectively preventing the sealing ring 3 from loosening due to vibration, temperature changes, etc., and improving the sealing reliability.

[0016] In some technical solutions, the lower wall of the sealing ring 3 is provided with a positioning groove 5, which is annular, and the convex ring 43 can be inserted into the positioning groove 5.

[0017] In this technical solution, the cooperation between the convex ring 43 and the positioning groove 5 can accurately position the sealing ring 3, preventing the sealing ring 3 from shifting during the extrusion process. At the same time, it increases the contact area between the extrusion ring 42 and the sealing ring 3, making the extrusion pressure distribution more uniform and further enhancing the sealing effect.

[0018] In some technical solutions, a retaining ring 6 is provided on the lower side wall of the sealing ring 3, and a retaining groove 7 is provided on the inner side wall of the annular groove 2 to cooperate with the retaining ring 6, so that the retaining ring 6 can be inserted into the retaining groove 7.

[0019] In this technical solution, the snap-fit ​​structure of the retaining ring 6 and the retaining groove 7 can pre-fix the sealing ring 3 in the early stage of installation, prevent the sealing ring 3 from shifting, facilitate the smooth progress of subsequent extrusion operations, and enhance the sealing ring 3's resistance to falling off.

[0020] In some technical solutions, the outer wall of the extrusion ring 42 is provided with two insertion holes 8, which are respectively located on the front and rear sides of the extrusion ring 42.

[0021] In this technical solution, the insertion hole 8 can be used to insert a rod-shaped tool, such as a special wrench. This special wrench can be referenced as a milling machine tool changer wrench, which facilitates the application of force to rotate the extrusion ring 42, reduces the difficulty of operation, and makes the installation and adjustment of the extrusion ring 42 more convenient and labor-saving.

[0022] In some technical solutions, the side wall of the oil filter 1 is provided with a threaded hole 9, and the oil filter 1 is installed on the outside of the connecting screw tube at the bottom of the external car engine through the threaded hole 9.

[0023] In this technical solution, the oil filter 1 proposed in this paper is existing technology. Its existing filter is also provided with threaded holes 9 for connection and installation with the external engine bottom wall.

[0024] In some technical solutions, the extrusion ring 42 has an L-shaped cross-section, and a reinforcing rib 10 is welded to the inner wall of the extrusion ring 42. The reinforcing rib 10 is located at the bend on the inner side of the extrusion ring 42.

[0025] In this technical solution, the reinforcing rib 10 can improve the structural strength of the bending point of the extrusion ring 42, prevent deformation due to stress during long-term use, and ensure the stability of the extrusion force.

[0026] Working principle: During installation, the sealing ring 3 is first embedded into the annular groove 2, and the sealing ring 3 is pre-fixed by the cooperation of the retaining ring 6 and the retaining groove 7. Then, the device is installed on the bottom wall of the external car engine. Then, the tool is inserted into the insertion hole 8 and rotated to make the extrusion ring 42 move upward and compress the sealing ring 3. At the same time, the protruding ring 43 on the extrusion ring 42 is inserted into the positioning groove 5 of the sealing ring 3, further ensuring that the sealing ring 3 is accurately positioned and evenly stressed, so that the sealing ring 3 fits tightly against the inner wall of the annular groove 2 and achieves a reliable seal.
