Description

Technical Field

[0001] This utility model relates to the field of fuel pump assembly technology, specifically a novel connection mechanism applicable to flanges and filters. Background Technology

[0002] The fuel pump assembly is a core component of a vehicle's fuel supply system. It is mainly used to extract fuel from the fuel tank and deliver it to the engine's fuel injection system or carburetor at a specified pressure and flow rate to meet the engine's fuel requirements.

[0003] In existing fuel pump assemblies, the flange is typically connected to the filter using a flexible hose. This connection method requires the filter to be supported and fixed by other mechanisms, increasing mold manufacturing costs, requiring more labor time for installation, and taking up a lot of space during product assembly, leading to increased installation costs and unstable quality. Therefore, a new connection mechanism is needed to solve the above-mentioned drawbacks and improve efficiency. Utility Model Content

[0005] This utility model relates to a novel connection mechanism suitable for flanges and filters, comprising:

[0006] Hot-press welding points are equidistantly distributed at the joint positions of the flange and filter;

[0007] A connecting hose is provided, with a first pair of connectors fixedly connected to the end of the connecting hose, and one end of the first pair of connectors is connected to a second pair of connectors respectively connected to the corresponding positions of the fuel pump and the filter.

[0008] Furthermore, the connecting hose is a corrugated hose.

[0009] Furthermore, a filter screen is provided inside the connecting hose on the side near the fuel pump.

[0010] Furthermore, the outer surface of the filter screen is provided with rectangular protrusions at equal intervals, and the rectangular protrusions abut against the grooves that are equally spaced on the inner wall of the connecting hose near the fuel pump.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-3 As shown, this utility model is a novel connection mechanism applicable to flanges and filters, comprising:

[0024] Hot-press welding points 11 are equidistantly distributed at the joint positions of the flange and the filter.

[0025] The flange and filter are integrated using a thermo-press welding connection instead of the original separate connection method using connecting hose 12. This makes the structure more stable, reduces the amount of connecting hose 12 used, helps to reduce costs, reduces the risk of connecting hose 12 breaking or falling off, and improves the overall quality of the fuel pump assembly.

[0026] A connecting hose 12 is provided, and a first pair of connectors 13 is fixedly connected to the end of the connecting hose 12. One end of the first pair of connectors 13 is connected to a second pair of connectors 14 that are respectively connected to the fuel pump and the filter at corresponding positions.

[0027] The connecting hose 12 is used to connect the fuel pump and the filter to achieve fuel delivery.

[0028] Connecting hose 12 is a corrugated hose;

[0029] The corrugated hose design allows for easy adjustment of the length of the connecting hose 12 to meet usage requirements.

[0030] A filter screen is installed inside the connecting hose 12 on the side near the fuel pump;

[0031] The filter screen can perform preliminary filtration of the oil in the oil circuit, which helps to improve the ability of subsequent secondary filtration by the filter.

[0032] The outer surface of the filter screen is provided with rectangular protrusions at equal intervals, and the rectangular protrusions abut against the grooves that are equally spaced on the inner wall of the connecting hose 12 near the fuel pump.

[0033] The interlocking of the rectangular protrusions and grooves secures the filter screen structurally and makes it easy to assemble and disassemble.

[0034] The end of the connecting hose 12 is provided with a bearing, and the middle part of the bearing is fitted with one end of the first connector 13. The other end surface of the first connector 13 and the inner wall of the second connector 14 are provided with threads at equal intervals, and the two are threadedly connected to each other.

[0035] The bearing is installed on the first joint 13 and the connection between the first joint 13 and the second joint 14 is completed by means of threads to ensure the tightness of the connection.

[0036] A sealing gasket is provided in the connection gap between the bearing, the first joint 13 and the connecting hose 12;

[0037] The sealing gasket ensures a tight connection and prevents oil leakage.

[0038] Working principle: The flange and filter are pre-connected and then integrally welded using hot-press welding. At this time, a sealing test is required. If no sealing problem is found after the sealing test, the ends of the connecting hose 12 are connected to the fuel pump and the filter respectively using the threaded connection between the first connector 13 and the second connector 14. Before this process, a filter screen is installed on one end of the connecting hose 12 through the contact between the rectangular protrusions and grooves. Then, the oil is pumped out of the fuel pump and delivered to the filter through the connecting hose 12. After being filtered by the filter, it flows to the engine through the oil outlet pipe, completing the supply of the entire fuel circuit.

[0039] This solution changes the original separate hose connection between the flange and filter in the fuel pump assembly to an integrated thermo-pressurized welding connection. This increases the stability of the device, reduces the use of excessive connecting hoses 12, lowers operating costs, simplifies the assembly process, saves time and effort, and helps improve operational efficiency. At the same time, it saves assembly space for the overall fuel pump bracket. Furthermore, by reducing the amount of connecting hoses 12 used, the risk of hose breakage and detachment is reduced, thus improving the overall quality of the fuel pump assembly.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
