Description

Technical Field

[0001] This utility model relates to the field of fuel filter technology, and in particular to a fuel filter that is easy to install. Background Technology

[0002] Fuel filters are common automotive components, primarily designed to prevent impurities in the fuel from entering the fuel pump and causing blockages. Existing fuel filters suffer from the following problems: First, fuel filters are typically fixed to a connecting post inside the vehicle using bolts. Due to the limited space inside the vehicle, installation is very inconvenient and significantly reduces installation efficiency. Second, while bolt fixing is a reliable method, with prolonged vehicle use, the connecting post or fuel filter itself may age, leading to an unstable connection between the fuel filter and the connecting post. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a fuel filter that is easy to install, improves installation efficiency, and ensures installation stability.

[0004] The technical solution of this utility model is as follows: A fuel filter that is easy to install includes a filter body and a connector component connected to the filter body. The connector component is provided with a positioning block. The positioning block is provided with a positioning groove, a positioning ring connected to the positioning groove, and a material passage groove. The material passage groove communicates with the positioning groove. The inner wall of the positioning ring is provided with a plurality of arc-shaped pieces. The arc-shaped pieces are evenly distributed around the central axis of the positioning ring. The arc-shaped pieces are integrally formed with the positioning ring. The arc-shaped pieces have a certain elasticity. There is a certain distance between two adjacent arc-shaped pieces. After the arc-shaped pieces are bent, the adjacent arc-shaped pieces will not contact each other.

[0005] Using the above technical solution, when installing a fuel filter, first, align the positioning ring with the connecting post in the car installation station, and then directly insert the connecting post into the gap between the arc-shaped pieces. Before installation, it is necessary to ensure that the distance between the inner wall of the arc-shaped piece and the center point of the positioning ring is less than the radius of the connecting post. Since the arc-shaped piece has a certain elasticity, it will deform after being subjected to compressive force, thereby keeping the relative position between the positioning ring and the connecting post stable, thus further ensuring that the fuel filter can be stably installed on the connecting post. This installation method is simple and convenient, and can ensure the stability of the installation structure.

[0006] A further feature of this invention is that the bottom of the feed trough is provided with a limiting groove, the cross-sectional shape of the limiting groove is circular, and the radius of the limiting groove is greater than the distance between the inner wall of the arc-shaped piece and the center point of the positioning ring.

[0007] By adopting the above technical solution, since the bottom of the feed trough is provided with a limiting groove, and the cross-sectional shape of the limiting groove is circular, when the connecting post is inserted into the feed trough, it must be ensured that the connecting post is inserted into the limiting groove before the installation is considered complete. This ensures that the connecting post and the positioning ring are coaxially set, thereby ensuring that the installation position of the fuel filter is not skewed when the fuel filter is installed on the connecting post, thus further ensuring the stability of the connection between the two.

[0008] A further feature of this invention is that the arc-shaped plate is provided with a plurality of serrated blocks evenly distributed on the inner wall of the arc-shaped plate, and the length of the serrated blocks is less than or equal to 1 mm.

[0009] By adopting the above technical solution, since the arc-shaped plate has several serrated blocks evenly distributed on the inner wall of the arc-shaped plate, the friction between the connecting post and the arc-shaped plate can be further improved, thereby further improving the stability of the fuel filter when it is installed on the connecting post.

[0010] A further feature of this invention is that the positioning ring, the arc-shaped piece, and the serrated block are all made of stainless steel.

[0011] By adopting the above technical solution, since the positioning ring, arc-shaped piece and serrated block are all made of stainless steel, stainless steel has good flexibility, good strength and high temperature resistance, which can avoid the positioning ring from easily deforming after being heated due to the material being too soft, thereby affecting the connection stability between the connecting column and the positioning ring.

[0012] A further feature of this invention is that the positioning ring has several connecting grooves, the positioning groove has several connecting blocks, the shape and size of the connecting blocks are adapted to the connecting grooves, and the positions of the connecting grooves and the connecting blocks correspond one-to-one.

[0013] By adopting the above technical solution, since the positioning ring is provided with several connecting grooves and the positioning groove is provided with several connecting blocks, the relative positional stability between the positioning ring and the positioning blocks can be guaranteed, thereby avoiding the instability of the connection structure between the connecting column and the fuel filter due to the relative displacement of the positioning ring during use.

[0018] like Figure 1-3 As shown, an easy-to-install fuel filter includes a filter body 1 and a connector component 2 connected to the filter body 1. The connector component 2 is provided with a positioning block 3. The positioning block 3 is provided with a positioning groove 4, a positioning ring 5 connected to the positioning groove 4, and a material passage 6. The material passage 6 communicates with the positioning groove 4. The inner wall of the positioning ring 5 is provided with a plurality of arc-shaped pieces 7. The arc-shaped pieces 7 are evenly distributed around the central axis of the positioning ring 5. The arc-shaped pieces 7 are integrally formed with the positioning ring 5. The arc-shaped pieces 7 have a certain elasticity. There is a certain distance between two adjacent arc-shaped pieces 7. When the arc-shaped pieces 7 are bent, the adjacent arc-shaped pieces 7 will not contact each other.

[0019] When installing a fuel filter, first align the locating ring 5 with the connecting post in the car's installation bay, then directly insert the connecting post into the gap between the arc-shaped pieces 7. Before installation, ensure that the distance between the inner wall of the arc-shaped piece 7 and the center point of the locating ring 5 is less than the radius of the connecting post. Since the arc-shaped piece 7 has a certain elasticity, it will deform under pressure, thus keeping the relative position between the locating ring 5 and the connecting post stable. This further ensures that the fuel filter can be stably installed on the connecting post. This installation method is simple and convenient, and ensures the stability of the installation structure.

[0020] The bottom of the feed trough 6 is provided with a limiting groove 8. The cross-sectional shape of the limiting groove 8 is circular, and the radius of the limiting groove 8 is greater than the distance between the inner wall of the arc-shaped piece 7 and the center point of the positioning ring 5.

[0021] Since the bottom of the feed trough 6 is provided with a limiting groove 8, and the cross-sectional shape of the limiting groove 8 is circular, when the connecting post is inserted into the feed trough 6, it must be ensured that the connecting post is inserted into the limiting groove 8 before the installation is considered complete. This ensures that the connecting post and the positioning ring 5 are coaxially set, thereby ensuring that the installation position of the fuel filter is not skewed when the fuel filter is installed on the connecting post, thus further ensuring the stability of the connection between the two.

[0022] The arc-shaped plate 7 is provided with a plurality of serrated blocks 9 evenly distributed on the inner wall of the arc-shaped plate 7, and the length of the serrated block 9 is less than or equal to 1 mm.

[0023] Since the arc-shaped plate 7 has several serrated blocks 9 evenly distributed on the inner wall of the arc-shaped plate 7, the friction between the two can be further improved when the connecting post is snapped onto the arc-shaped plate 7, thereby further improving the stability of the fuel filter when it is installed on the connecting post.

[0024] The positioning ring 5, the arc-shaped piece 7, and the serrated block 9 are all made of stainless steel.

[0025] Since the positioning ring 5, the arc-shaped piece 7, and the serrated block 9 are all made of stainless steel, stainless steel has good flexibility, good strength, and high temperature resistance. This can prevent the positioning ring 5 from easily deforming when heated due to its softness, thus affecting the connection stability between the connecting column and the positioning ring 5.

[0026] The positioning ring 5 is provided with a plurality of connecting grooves 10, and the positioning groove 4 is provided with a plurality of connecting blocks 11. The shape and size of the connecting blocks 11 are adapted to the connecting grooves 10, and the positions of the connecting grooves 10 and the connecting blocks 11 correspond one-to-one.

[0027] Since the positioning ring 5 is provided with several connecting grooves 10 and the positioning groove 4 is provided with several connecting blocks 11, the relative positional stability between the positioning ring 5 and the positioning block 3 can be guaranteed, thereby avoiding the instability of the connection structure between the connecting column and the fuel filter due to the relative displacement of the positioning ring 5 during use.
