[0032] Further, the positioning protrusion 3 is arranged on the gasket body 1, and the positioning groove 4 is arranged on the threaded plate 2. The positioning protrusion 3 is located on the side of the gasket body 1 facing the threaded plate 2, and the positioning groove 4 is located on the side of the threaded plate 2 facing the gasket body 1. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, during installation, the positioning protrusion 3 on the gasket body 1 is inserted into the positioning groove 4 on the threaded plate 2. The structure is simple, and the assembly and disassembly is convenient and fast, saving time and effort.
[0033] Furthermore, the positioning protrusion 3 is arranged on the circumferential surface of the gasket body 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the positioning protrusion 3 protrudes from the outside of the gasket body 1, and it is easy to check when the positioning protrusion 3 is inserted into the positioning groove 4, which is more convenient and quick.
[0034] Furthermore, the positioning protrusion 3 and the gasket body 1 are an integrally formed structure, the connection is firm and reliable, and the positioning effect is better.
[0035] Furthermore, the positioning groove 4 is a semicircular groove, and the positioning protrusion 3 is a semicircular protrusion, which can prevent the positioning protrusion 3 from rotating in the positioning groove 4 and avoid misalignment between the gasket body 1 and the threaded plate 2.
[0036] Furthermore, the threaded plate 2 includes a sleeve 2-1 and an annular plate 2-2. The sleeve 2-1 has an internal thread. The gasket body 1 is sleeved on the outer periphery of the sleeve 2-1. The annular plate 2-2 is arranged on the outer periphery of the sleeve 2-1. The gasket body 1 is welded to the annular plate 2-2. The annular plate 2-2 is provided with an oil inlet 5. The positioning protrusion 3 and the positioning groove 4 are located on the annular plate 2-2. Figure 3 , Figure 4 and Figure 5As shown, the gasket body 1 is sleeved on the outer periphery of the sleeve 2-1, and the sleeve 2-1 can play a positioning role for the gasket body 1 to prevent the gasket body 1 from shifting in the radial direction. The sleeve 2-1 has an internal thread, which is convenient for connecting the threaded plate 2 to the engine. The edge of the gasket body 1 is in contact and sealed with the annular plate 2-2 and fixed together by spot welding. One of the positioning protrusion 3 and the positioning groove 4 is located on the annular plate 2-2, and the other is located on the gasket body 1.
[0037] Furthermore, the sleeve 2 - 1 and the annular plate 2 - 2 are integrally formed and the connection is firm and reliable, so that the overall strength of the threaded plate 2 is higher.
[0038] Furthermore, the gasket body 1 includes an inner ring sheet 1-1, an outer ring sheet 1-2, and a connecting tube 1-3. The inner ring sheet 1-1 is sleeved on the outer periphery of the sleeve 2-1. A gap is left between the inner ring sheet 1-1 and the annular plate 2-2. A guide groove 6 is provided on the inner ring sheet 1-1. The guide groove 6 and the oil inlet 5 are arranged one by one. The inner diameter of the outer ring sheet 1-2 is larger than the outer diameter of the inner ring sheet 1-1. The outer ring sheet 1-2 is in contact with and welded to the annular plate 2-2. The oil inlet 5 is located on the inner side of the outer ring sheet 1-2. The positioning protrusion 3 and the positioning groove 4 are located on the outer ring sheet 1-2. The connecting tube 1-3 is arranged between the inner ring sheet 1-1 and the outer ring sheet 1-2.

Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the inner ring sheet 1-1 and the outer ring sheet 1-2 are connected together by the connecting tube 1-3, so that there is a sufficiently large accommodation space between the gasket body 1 and the threaded plate 2. After the oil enters the accommodation space between the gasket body 1 and the threaded plate 2 through the oil inlet 5 on the threaded plate 2, it is evenly diverted into the housing of the filter through the guide groove 6 on the diverter gasket 1. One of the positioning protrusion 3 and the positioning groove 4 is located on the outer ring sheet 1-2, and the other is located on the threaded plate 2.
[0039] Furthermore, the inner ring piece 1-1, the outer ring piece 1-2 and the connecting tube 1-3 are an integrally formed structure, so that the overall strength of the gasket body 1 is higher and the connection is more secure.
[0040] Furthermore, the middle portion of the annular plate 2-2 is bent and extended toward a side away from the inner ring sheet 1-1 to form an arc-shaped protrusion, and the oil inlet 5 is arranged at the arc-shaped protrusion. Figure 4 As shown, by providing the arc-shaped protrusion, the accommodation space between the gasket body 1 and the threaded plate 2 can be further increased.
[0041] In this embodiment, the positioning protrusion 3 is arranged on the gasket body 1, and the positioning groove 4 is arranged on the threaded plate 2. Before welding, the gasket body 1 is first mounted on the sleeve 2-1 of the threaded plate 2, so that the positioning protrusion 3 is plugged into the positioning groove 4, and then the gasket body 1 and the threaded plate 2 are connected together by spot welding, and the outer ring plate 1-2 of the gasket body 1 is contacted and sealed with the annular plate 2-2 of the threaded plate 2. The positioning protrusion 3 cooperates with the positioning groove 4 to position the gasket body 1 and the threaded plate 2, thereby ensuring that the oil inlet 5 on the threaded plate 2 and the guide groove 6 on the diverter gasket 1 are arranged one by one to avoid deviation, and no misalignment will occur between the threaded plate 2 and the diverter gasket 1 during the spot welding process, which can improve the uniformity of the connection between the oil inlet 5 and the guide groove 6.
