Description

Technical Field

[0001] This utility model relates to the field of fuel filter technology, and in particular to an installation device for a fuel filter. Background Technology

[0002] In the current technology, with the steady and continuous development of China's automotive industry, auto parts have also developed accordingly. As a consumable auto part, fuel filters have a large market demand. Similarly, with the increasing improvement of people's living standards, people are placing higher demands on the quality of auxiliary equipment parts for automobiles. Fuel filters are crucial filtering components that prevent impurities such as particles and water in the fuel from entering the fuel system, causing fuel system blockage and cylinder scratches. Existing external fuel filters are mostly fixed to the vehicle body bracket or fuel tank bracket with screws. Since fuel filters are consumable parts and need to be replaced periodically, disassembly and assembly are cumbersome due to the traditional installation method requiring screws or bolts. This adds extra parts such as bolts, washers, and clamps, and the operator must align multiple mounting holes, significantly increasing usage and labor costs, making installation and disassembly very inconvenient.

[0003] Chinese utility model patent application number 202323220343.2 discloses an easy-to-install automotive fuel filter device, including a mounting base. A clamping mechanism is mounted on the bottom of the mounting base. The clamping mechanism includes a rotating shaft, with a driven gear fixedly connected to the upper end of the outer surface of the rotating shaft. A fixing block is fixedly connected to the right side of the bottom of the mounting base. A rotating rod is rotatably connected to the inner cavity of the fixing block. A driving gear is fixedly connected to the left end of the rotating rod, and the driving gear meshes with the driven gear. A compression plate is fixedly connected to the outer surface of the rotating rod, and a compression spring is fixedly connected to the left side of the compression plate. However, this easy-to-install automotive fuel filter device only uses clamping arms to install and fix the fuel filter, resulting in poor installation stability. This may cause the fuel filter to shift or even fall off, affecting its working performance. Summary of the Invention

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. An installation device for a fuel filter includes a mounting base 1, which is mounted on a fuel pump. It also includes an end mechanism for forming an assembled end structure, a positioning mechanism for forming an adjustable positioning structure, and a hydraulic passage mechanism for forming a detachable hydraulic passage. The end mechanism is located in the middle of the mounting base 1, the positioning mechanism is located at one end of the end mechanism, and the hydraulic passage mechanism is mounted at the end of the mounting base 1. A schematic diagram of the overall structure of this invention is shown below. Figure 1 As shown.

[0019] Mounting base 1 is configured as a tubular seat structure. Mounting holes are provided at both the upper and lower ends of mounting base 1, and these holes are arranged independently. A mounting cavity is provided on one side of the middle portion of mounting base 1. A positioning mechanism is assembled on the side of mounting base 1 with the mounting cavity. Mounting base 1 is assembled onto the fuel pump via screws. The mounting holes serve as oil inlet and outlet channels on mounting base 1, and the mounting cavity serves as the mounting structure on the side of mounting base 1 to meet the installation requirements of the positioning mechanism. A cross-sectional view of mounting base 1 and positioning mechanism in conjunction is shown below. Figure 2 As shown.

[0020] The end-capping mechanism includes an end-capping core tube 2 and an end-capping plug 3. The end-capping core tube 2 is located in the middle of the mounting base 1 and is embedded in the mounting base 1. One end of the end-capping core tube 2 protrudes from the side of the mounting base 1 away from the mounting cavity and has an external thread on its side. The end-capping plug 3 is located at the end of the end-capping core tube 2 that protrudes from the mounting base 1 and is threadedly connected to the end-capping core tube 2. The end-capping mechanism, through the cooperation of the end-capping core tube 2 and the end-capping plug 3, forms a detachable end-capping structure on the mounting base 1 to meet the sealing requirements of the mounting base 1. To facilitate disassembly and maintenance, the end core tube 2 serves as the liquid inlet structure inside the mounting base 1 and provides installation support for the end plug 3. The end plug 3 is used to assemble onto the mounting base 1 through the end core tube 2 and cooperate with the end core tube 2 to achieve a seal of the liquid inlet structure. When the installation device needs to be disassembled and maintained, or when the end core tube 2 is damaged or blocked, the end plug 3 can be removed from the end core tube 2 to remove the end core tube 2 from one side of the mounting cavity, thereby realizing the disassembly of the installation device.

[0021] The end of the end core tube 2 near the end plug 3 is provided with a liquid inlet chamber, which is connected to the mounting hole at the upper end of the mounting base 1 through a through hole. The end of the end core tube 2 away from the end plug 3 is provided with a liquid inlet passage, which is connected to the liquid inlet chamber and the mounting cavity at both ends respectively. The liquid inlet chamber is used as an oil-containing structure in the end core tube 2, and the liquid inlet passage is used to form a liquid inlet structure together with the liquid inlet chamber to meet the liquid inlet requirements of the fuel filter.

[0022] The positioning mechanism includes a positioning end block 4, a sealing gasket 5, and an installation assembly. The positioning end block 4 is located on the side of the mounting base 1 where the mounting cavity is located and is threadedly connected to the mounting base 1 through the mounting cavity. One end of the positioning end block 4 protrudes from the mounting cavity of the mounting base 1. The sealing gasket 5 is located on the side of the positioning end block 4 near the mounting base 1 and is snap-fitted to the positioning end block 4 through a groove. There are two sets of installation assemblies, which are symmetrically arranged on the end of the positioning end block 4 that protrudes from the mounting base 1. The positioning mechanism, through the cooperation of the positioning end block 4, the sealing gasket 5, and the installation assembly, forms the installation positioning structure on the mounting base 1, thereby providing installation support for the fuel filter. The positioning end block 4 is used as a detachable end block structure on the mounting base 1, thereby providing installation support for the installation assembly and the inlet end of the fuel filter. The sealing gasket 5 is used to achieve a seal between the positioning end block 4 and the inner wall of the mounting cavity of the mounting base 1. The installation assembly is used to clamp and fix the side of the fuel filter.

[0023] The mounting assembly includes a mounting bracket 6, a mounting screw 7, and a mounting clamp 8. The mounting bracket 6 is located at the end of the positioning end block 4 that protrudes from the mounting base 1 and is fixedly connected to the positioning end block 4. The mounting screw 7 is located at the end of the mounting bracket 6 away from the positioning end block 4 and passes through the mounting bracket 6, threadedly connected to the mounting bracket 6. The mounting clamp 8 is located at the end of the mounting screw 7 near the positioning end block 4 and is rotatably connected to the mounting screw 7. The mounting assembly, through the cooperation of the mounting bracket 6, the mounting screw 7, and the mounting clamp 8, forms a clamping mounting structure to clamp and fix the side of the fuel filter. The mounting bracket 6 provides mounting support for the mounting screw 7, and the mounting screw 7 provides mounting support for the mounting clamp 8. Its relative rotation with the mounting bracket 6 drives the mounting clamp 8 to move up and down. The mounting clamp 8, under the action of the mounting screw 7, moves up and down to adjust the distance between the two sets of mounting clamps 8, thereby clamping and fixing the side of the fuel filter. A schematic diagram of the mounting assembly structure of this utility model is shown below. Figure 3 As shown.

[0024] It also includes an anti-slip pad 9, which is located on the side of the mounting block 8 away from the mounting screw 7 and is fixedly connected to the mounting block 8. The anti-slip pad 9 serves as an anti-slip mechanism on the inner side of the mounting block 8, thereby improving the anti-slip effect between the mounting block 8 and the side bracket of the fuel filter and improving the installation stability of the fuel filter.

[0025] The positioning end block 4 is configured as a tubular end structure, and its internal structure corresponds to the inlet end of the fuel filter as a stepped through hole structure. The mounting clamp block 8 corresponds to the side of the fuel filter as an arc-shaped clamp block structure. The inlet end of the fuel filter is inserted and snapped into the positioning end block 4 through the stepped through hole structure. The two sets of oppositely arranged mounting clamp blocks 8 form a clamping structure to clamp the side of the fuel filter by installing anti-slip pads 9. The stepped through hole structure is used to meet the assembly and positioning requirements of the inlet end of the fuel filter, and the mounting clamp block 8 with the arc-shaped clamp block structure can stably clamp the fuel filter.

[0026] The hydraulic system includes a hydraulic screw and a fuel nozzle 11. The hydraulic screw is located at the end of the mounting base 1 and is threadedly connected to the mounting base 1 through a mounting hole. The fuel nozzle 11 is located between the hydraulic screw and the mounting base 1 and is sleeved with the hydraulic screw. The fuel nozzle 11 is assembled on the mounting base 1 through the hydraulic screw. One end of the fuel nozzle 11 is an open structure. The interior of the hydraulic screw is a hollow structure, and its internal hollow structure communicates with the interior of the fuel nozzle 11 through a through hole. The hydraulic system, through the cooperation of the hydraulic screw and the fuel nozzle 11, constitutes the hydraulic system structure on the mounting device to meet the inlet and outlet fluid requirements of the fuel filter. The hydraulic screw serves as a detachable mounting structure on the mounting base 1, thereby meeting the installation and fluid flow requirements of the fuel nozzle 11. The fuel nozzle 11 serves as the hydraulic system structure on the mounting device, thereby meeting the inlet and outlet fluid requirements of the fuel filter.

[0027] The hydraulic system has two sets, which are respectively located at the upper and lower ends of the mounting base 1 and connected to the corresponding mounting holes. The upper hydraulic system serves as the inlet structure, connecting to the inlet end of the fuel filter through the inlet chamber and the mounting chamber. The lower hydraulic system serves as the outlet structure, connecting to the outlet end of the fuel filter. The lower part of the mounting base 1 has an oil outlet corresponding to the outlet structure, which connects to the mounting hole at the lower part. The outlet connects to the inlet of the fuel pump through the oil outlet. The hydraulic system enables the connection between external fuel and the inlet end of the fuel filter, as well as the connection between the outlet end of the fuel filter and the inlet of the fuel pump.

[0028] Working principle: In use, mount the mounting base 1 onto the fuel pump using screws. Insert the end core tube 2 into the middle of the mounting base 1, ensuring that its threaded end protrudes beyond the mounting base 1. Thread the end plug 3 onto the protruding end of the end core tube 2. Thread the positioning end block 4 onto the side of the mounting base 1 with the mounting cavity. Then, insert the fuel filter's inlet end into the stepped through-hole structure of the positioning end block 4. Rotate the mounting screw 7 to clamp and fix the side of the fuel filter with the mounting clamp 8. The fuel filter is now installed and fixed at both the end and side. In operation, external fuel enters the upper mounting hole through the upper fuel nozzle 11 and then enters the inlet chamber through the through hole. It then flows into the inlet end of the fuel filter along the inlet passage. After the fuel filter filters the fuel, the filtered fuel flows into the lower fuel nozzle 11 through the fuel filter outlet and then into the fuel pump inlet through the lower mounting hole and the fuel outlet, thus meeting the fuel pump's fuel requirements.

[0029] The beneficial effects of this utility model are that it has an end mechanism and a positioning mechanism working together to form a composite installation structure, which can position the end and side of the fuel filter to prevent it from shifting or falling off. It has strong assembly stability and ensures the working effect of the fuel filter. It also has a liquid passage mechanism to form an assembled inlet and outlet liquid structure, which facilitates disassembly and maintenance. It can be repaired and replaced according to actual use needs, and has high flexibility in use.

[0030] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
