It is usually made of metal or high-strength engineering plastics and has a specific shape and structure to ensure that it fits tightly with the filter and other related components to form a complete fuel filtration system.

[0003] For example, Chinese patent publication number CN218177352U discloses a base assembly of a fuel filter, which includes a base body, an oil inlet, an oil outlet, and an oil pump assembly provided on the base body, a vertical pipe provided on the inner side of the base body, and the vertical pipe connected to the oil outlet; a pump chamber is provided inside the oil pump assembly, and the pump chamber is connected to the vertical pipe through an oil inlet channel; a first one-way valve is provided in the vertical pipe, a second one-way valve is provided in the oil inlet channel, and a third one-way valve is provided in the oil outlet channel, and the valve seats of the first one-way valve, the second one-way valve, and the third one-way valve are fixed to the base body by welding, and an interference weld surface is formed between each one-way valve and the base body, and the weld surface serves as a sealing surface to achieve sealing.

[0004] When installing a fuel filter inside a catenary work vehicle, it is necessary to constantly adjust the position of the fuel filter to ensure that the fuel filter can be accurately installed in the center of the mounting base. However, due to the small installation space inside the catenary work vehicle, when adjusting the installation position of the fuel filter, the fuel filter will block the installer's field of vision, causing the installer to spend a long time adjusting the position of the fuel filter, resulting in low installation efficiency. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that due to the narrow installation space inside the contact network work vehicle, the fuel filter will block the installation worker's field of vision when adjusting the installation position of the fuel filter, resulting in the installer needing a long time to adjust the position of the fuel filter. A fuel filter base is proposed to solve the problem in the prior art that the fuel filter will block the installation worker's field of vision when adjusting the installation position of the fuel filter, thereby causing the installer to spend a long time to adjust the position of the fuel filter.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a fuel filter base, including a mounting base, one side of the mounting base is fixedly connected to a positioning pipe, the other end of the positioning pipe is fixedly connected to a dual-channel oil supply pipeline assembly, one side of the mounting base is fixedly installed with a positioning ring, one side of the mounting base is fixedly connected to a mounting side plate, one end of the mounting side plate is symmetrically provided with connecting grooves, and bolts are movably passed through the interior of the two connecting grooves.

[0007] Preferably, the dual-channel oil supply pipeline assembly includes two oil supply pipelines and an oil pipe connecting compartment, the two oil supply pipelines are fixedly connected to the oil pipe connecting compartment respectively, and the other end of the positioning pipeline is fixedly connected to the oil pipe connecting compartment.

[0008] Preferably, oil pipe connection ports are respectively provided at both ends of the oil supply pipeline.

[0010] Preferably, a mounting snap ring is fixedly connected to the inner side of the positioning ring.

[0011] Preferably, a slot is provided on the inner side of the rubber protective sleeve, and the mounting snap ring is movably engaged with the inside of the slot.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. In the present invention, the center of the bottom end of the fuel filter is aligned with the positioning pipe on the mounting base for installation. The positioning pipe extends into the interior of the bottom end of the fuel filter, performing preliminary positioning of the fuel filter. The fuel filter is fixed by the positioning pipe at the center of the positioning ring. This eliminates the need for the installer to repeatedly adjust the installation position of the fuel filter, thereby improving installation efficiency and facilitating the use of specialized tools for installation, removal, and maintenance of the fuel filter.

[0022] The following details the specific configuration and function of this embodiment. First, the mounting side plate 12 on one side of the mounting base 1 is attached to the panel to be mounted. Then, bolts 122 are inserted through the mounting threaded holes in the panel to pre-secure the mounting base 1 to one side of the panel. When installing the fuel filter, the center of the bottom end of the fuel filter is aligned with the positioning pipe 2 on the mounting base 1, so that the positioning pipe 2 extends into the interior of the bottom end of the fuel filter. This performs preliminary positioning of the fuel filter, so that the fuel filter is fixed by the positioning pipe 2 at the center of the positioning ring 11. This eliminates the need for the installer to repeatedly adjust the installation position of the fuel filter, thereby improving installation efficiency and facilitating the installer to use specialized tools for installation, removal, and maintenance of the fuel filter. The corresponding connector is then rotated and secured to complete the installation of the fuel filter. Furthermore, when installing the fuel filter, one end of the fuel filter is positioned inside the positioning ring 11, with the rubber protective sleeve 111 clamped between the positioning ring 11 and the fuel filter, ensuring that the fuel filter is stably clamped inside the positioning ring 11.
