AI Technical Summary
[0002]燃油过滤器是一种常见的汽车零部件，其主要作用是防止燃油中的杂质进入燃油泵中造成堵塞，现有技术中，由于汽车内部安装零部件的空间有限，但是，为了增加燃油过滤器的过滤性能，需要尽可能的增加燃油过滤器上无纺布的面积，因此，需要使用弯折式的燃油过滤器以满足上述需求，现有的弯折式过滤器存在以下问题：第一，燃油过滤器的弯折部分无法得到有效固定，容易导致燃油过滤器弯折部分变形，进而影响燃油过滤器整体对燃油的过滤效率；第二，现有的燃油过滤器的弯折部分在固定后，容易与燃油过滤器主体部分发生接触，这样会影响燃油过滤器与燃油之间的接触面积，降低过滤效率
[0011]采用上述技术方案，由于限位凸块外表面设有固定连接于限位凸块的橡胶套，可以保证当卡接块卡接在定位柱上时，限位凸块与定位块始终保持紧密配合，避免由于长期使用导致限位凸块磨损进而影响燃油过滤器整体结构的稳定性，从而可以提高本燃油过滤器对燃油的过滤效率。

Description
Technical Field
[0001] This utility model relates to the field of fuel filter technology, and in particular to a fixing structure for a bent fuel filter. Background Technology
[0002] Fuel filters are common automotive components, primarily designed to prevent impurities in the fuel from clogging the fuel pump. Currently, due to limited space inside vehicles, increasing the area of the non-woven fabric on the fuel filter is crucial for improving its filtration performance. Therefore, pleated fuel filters are often used to meet this requirement. However, existing pleated filters have the following problems: First, the pleated portion of the fuel filter cannot be effectively fixed, easily leading to deformation and affecting the overall filtration efficiency. Second, after fixing, the pleated portion of existing fuel filters can easily come into contact with the main body of the filter, reducing the contact area between the filter and the fuel and lowering filtration efficiency. Summary of the Invention
[0003] To address the aforementioned problems, this invention provides a fixed structure for a bent fuel filter that can improve fuel filtration efficiency and enhance the overall structural stability of the fuel filter.
[0004] The technical solution of this utility model is as follows: A fixing structure for a bent fuel filter includes a filter body, a bent portion connected to the filter body, and a connector component connected to the filter body. The connector component is provided with a positioning post and a positioning block connected to the positioning post. The bent portion is provided with two connecting blocks and a snap-fit block connected to the connecting blocks. The snap-fit block has a first wedge surface on its surface, and the positioning block has two second wedge surfaces. The two snap-fit blocks are symmetrically arranged with the central axis of the positioning post as the axis, and the two second wedge surfaces are symmetrically arranged with the central axis of the positioning post as the axis. The spacing between the two snap-fit blocks is adapted to the width of the positioning post, and the spacing between the two connecting blocks is adapted to the width of the positioning block. The snap-fit block can be snapped onto the positioning post.
[0005] Using the above technical solution, when installing this fuel filter, firstly, rotate the bent part 90 degrees so that the positioning block aligns with the gap between the two snap-fit blocks. Then, press the snap-fit block into the positioning post. Since the snap-fit block surface has a first wedge surface and the positioning block has two second wedge surfaces, the snap-fit block can be easily slid in. At the same time, since the distance between the two snap-fit blocks is adapted to the width of the positioning post, and the distance between the two connecting blocks is adapted to the width of the positioning block, it can be ensured that the relative position of the snap-fit block and the positioning post is stable after the snap-fit block is snapped into the positioning post, thereby ensuring the stability of the overall structure of the fuel filter. This can increase the contact area between the fuel filter and the fuel and improve the filtration efficiency of the fuel filter while saving installation space.
[0006] A further feature of this invention is that the filter body and the bending portion are respectively provided with a first keel and a second keel, and the connecting block is integrally formed with the second keel.
[0007] By adopting the above technical solution, since the filter body and the bending part are respectively provided with the first keel and the second keel, not only can the filter body and the bending part be opened up, increasing the contact area between the filter body and the bending part and the fuel, and improving the fuel filtration efficiency, but also the positional stability between the connecting block and the bending part can be improved, thereby avoiding contact between the bending part and the joint component or the filter body.
[0008] A further feature of this invention is that the second keel is provided with a limiting protrusion, which is located between two connecting blocks. When the snap-fit block is snapped onto the positioning post, the limiting protrusion and the positioning block are in a contacting state. At this time, the bent part does not contact the filter body and the connector component.
[0009] By adopting the above technical solution, since the limiting protrusion is located between the two connecting blocks, and when the snap-fit block is snapped onto the positioning post, the limiting protrusion and the positioning block are in abutting state. Therefore, it can be ensured that the bent part does not contact the filter body and the connector component, and further ensure that the fuel can fully contact the filter body and the bent part, thereby improving the filtration efficiency of the fuel filter.
[0010] A further feature of this invention is that a rubber sleeve is fixedly connected to the outer surface of the limiting protrusion, and the shape of the inner wall of the rubber sleeve is adapted to the shape and size of the outer surface of the limiting protrusion.
[0011] By adopting the above technical solution, since the outer surface of the limiting protrusion is provided with a rubber sleeve that is fixedly connected to the limiting protrusion, it can be ensured that when the snap-fit block is snapped onto the positioning post, the limiting protrusion and the positioning block always maintain a tight fit, avoiding wear of the limiting protrusion due to long-term use, which would affect the stability of the overall structure of the fuel filter, thereby improving the filtration efficiency of the fuel filter.

[0016] like Figure 1-3 As shown, a fixed structure for a bent fuel filter includes a filter body 1, a bent portion 2 connected to the filter body 1, and a connector component 3 connected to the filter body 1. The connector component 3 is provided with a positioning post 4 and a positioning block 5 connected to the positioning post 4. The bent portion 2 is provided with two connecting blocks 6 and a snap-fit block 7 connected to the connecting blocks 6. The snap-fit block 7 has a first wedge surface 8 on its surface, and the positioning block 5 has two second wedge surfaces 9. The two snap-fit blocks 7 are symmetrically arranged with the central axis of the positioning post 4 as the axis, and the two second wedge surfaces 9 are symmetrically arranged with the central axis of the positioning post 4 as the axis. The spacing between the two snap-fit blocks 7 is adapted to the width of the positioning post 4, and the spacing between the two connecting blocks is adapted to the width of the positioning block 5. The snap-fit block 7 can be snapped onto the positioning post 4.
[0017] When installing this fuel filter, first, rotate the bent part 2 90 degrees so that the positioning block 5 aligns with the gap between the two snap-fit blocks 7. Then, press the snap-fit block 7 into the positioning post 4. Since the snap-fit block 7 has a first wedge surface 8 and the positioning block 5 has two second wedge surfaces 9, the snap-fit block 7 can be easily slid in. At the same time, since the distance between the two snap-fit blocks 7 is adapted to the width of the positioning post 4, and the distance between the two connecting blocks is adapted to the width of the positioning block 5, it can be ensured that the relative position of the snap-fit block 7 and the positioning post 4 is stable after the snap-fit block 7 is snapped into the positioning post 4, thereby ensuring the stability of the overall structure of the fuel filter. This can increase the contact area between the fuel filter and the fuel and improve the filtration efficiency of the fuel filter while saving installation space.
[0018] The filter body 1 and the bending part 2 are respectively provided with a first keel 10 and a second keel 11, and the connecting block 6 is integrally formed with the second keel 11.
[0019] Since the filter body 1 and the bending part 2 are respectively provided with the first keel 10 and the second keel 11, the filter body 1 and the bending part 2 can be opened up to increase the contact area between the filter body 1 and the bending part 2 and the fuel, thereby improving the fuel filtration efficiency. It can also improve the positional stability between the connecting block 6 and the bending part 2, thereby preventing the bending part 2 from contacting the connector part 3 or the filter body 1.
[0020] The second keel 11 is provided with a limiting protrusion 12, which is located between two connecting blocks 6. When the snap-fit block 7 is snapped onto the positioning post 4, the limiting protrusion 12 and the positioning block 5 are in abutting state. At this time, the bending part 2 does not contact the filter body 1 and the connector component 3.
[0021] Since the limiting protrusion 12 is located between the two connecting blocks 6, and when the snap-fit block 7 is snapped onto the positioning post 4, the limiting protrusion 12 and the positioning block 5 are in abutting state. Therefore, it can be ensured that the bent part 2 does not contact the filter body 1 and the connector part 3, and further ensure that the fuel can fully contact the filter body 1 and the bent part 2, thereby improving the filtration efficiency of the fuel filter.
[0022] The outer surface of the limiting protrusion 12 is provided with a rubber sleeve 13 fixedly connected to the limiting protrusion 12, and the shape of the inner wall of the rubber sleeve 13 is adapted to the shape and size of the outer surface of the limiting protrusion 12.
[0023] Because the outer surface of the limiting protrusion 12 is provided with a rubber sleeve 13 that is fixedly connected to the limiting protrusion 12, it can be ensured that when the snap-fit block 7 is snapped onto the positioning post 4, the limiting protrusion 12 and the positioning block 5 always maintain a tight fit, avoiding wear of the limiting protrusion 12 due to long-term use, which would affect the stability of the overall structure of the fuel filter, thereby improving the filtration efficiency of the fuel filter.
