Description

Technical Field

[0001] This utility model belongs to the field of oil pipe joint technology, and particularly relates to a high-sealing automotive oil inlet pipe joint. Background Technology

[0002] Oil pipe fittings are classified into straight-through, right-angle, tee, and cross types according to the direction of the passage. They are key components for connecting oil pipes to hydraulic components, oil pipes to mounting plates, and other equipment. Their main functions are to achieve a firm connection, a reliable seal, and convenient installation. Regarding material and performance requirements, oil pipe fittings are usually made of alloy structural steel to ensure their corrosion resistance and mechanical strength under high temperature and high pressure environments. The design of the fittings also needs to consider sealing performance.

[0003] Oil leakage is a common problem between the oil pipe joint and the oil pipe body in existing technologies. Oil stains easily overflow from the gap between the oil pipe body and the oil pipe joint, resulting in poor sealing and affecting the stability of the seal. At the same time, the connection between the oil pipe body and the oil pipe joint is cumbersome and inconvenient for disassembly and replacement. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a high-sealing automotive oil inlet pipe joint. The oil pipe body and the oil pipe joint are connected and disassembled quickly through a quick-connect structure. A sealing element is provided between the oil pipe body and the oil pipe joint, and sealing rubber rings are provided on both sides of the sealing element. When the oil pipe body and the oil pipe joint are connected through the quick-connect structure, the oil pipe body and the oil pipe joint squeeze the sealing element, thereby squeezing the sealing rubber rings to achieve a sealing effect. At the same time, it also facilitates quick disassembly and assembly between the oil pipe body and the oil pipe joint.

Detailed Implementation

[0022] like Figures 1 to 4 As shown, this utility model discloses a high-sealing automotive fuel inlet connector, comprising a fuel pipe body 1, a fuel pipe connector 2, a fuel nozzle 3, and a sealing element 4. One end of the fuel pipe body 1 is connected to the fuel pipe connector 2, and the other end of the fuel pipe connector 2 is connected to the fuel nozzle 3. A quick-connect structure is provided at the connected end of the fuel pipe body 1 and the fuel pipe connector 2, enabling connection between them. The sealing element 4 is positioned between the fuel pipe body 1 and the fuel pipe connector 2, with sealing rubber rings on both sides. When the fuel pipe body 1 and the fuel pipe connector 2 are connected, the sealing rubber rings are compressed to achieve a sealing effect. The quick-connect structure allows for rapid assembly and disassembly. The quick-connect structure facilitates rapid assembly and disassembly of the fuel pipe body 1 and the fuel pipe connector 2. The sealing element 4 is positioned between the fuel pipe body 1 and the fuel pipe connector 2, with sealing rubber rings on both sides. When connecting the fuel pipe body 1 and the fuel pipe connector 2 via the quick-connect structure, the sealing element 4 is compressed by the fuel pipe body 1 and the fuel pipe connector 2, thereby compressing the sealing rubber rings to achieve a sealing effect. This also facilitates rapid assembly and disassembly between the fuel pipe body 1 and the fuel pipe connector 2.

[0023] The quick-connect structure includes a first flange 5 and a second flange 6. The first flange 5 is installed on the oil pipe body 1. The first flange 5 is provided with a limiting hole 8, and a constriction portion 10 is provided in the limiting hole 8. The end of the oil pipe body 1 that is connected to the oil pipe joint 2 is provided with a flared portion 9, which is limited in the constriction portion 10. The second flange 6 is fixedly installed at the end of the oil pipe joint 2 that is connected to the oil pipe body 1. The first flange 5 and the second flange 6 are provided with corresponding mounting holes 7. The first flange 5 and the second flange 6 are connected by bolts through the mounting holes 7.

[0024] The sealing element 4 has a sealing groove 15 near the oil pipe connector 2. A sealing rubber ring 16 is installed in the sealing groove 15. The sealing rubber ring 16 abuts against the end of the oil pipe connector 2. The sealing element 4 has an inclined part 11 and a horizontal part 12 near the oil pipe body 1. The inclined part 11 and the horizontal part 12 are connected. The oil pipe body 1, the inclined part 11 and the horizontal part 12 are integrally formed. The inclined part 11 abuts against the inner wall of the flared part 9. The horizontal part 12 is inserted into the oil pipe body 1. The inclined part 11 has a sealing groove 13. A sealing rubber ring 14 is installed in the sealing groove 13. The inclined part 11 and the flared part 9 squeeze the sealing rubber ring 14. The side of the sealing element 4 near the oil pipe body 1 is limited in the limiting hole 8.

[0025] Through the above structural design, when the oil pipe body 1 is connected to the oil pipe joint 2, the sealing element 4 is first limited in the limiting hole 8 of the first flange 5. Then, the oil pipe joint 2 and the oil pipe body 1 are connected and fixed through the first flange 5 and the second flange 6. As the bolts are gradually tightened, the sealing element 4 and the oil pipe joint 2 are gradually squeezed, thereby squeezing the sealing rubber ring 16, thus preventing the formation of gaps between the sealing element 4 and the oil pipe joint 2 and causing leakage. During the fixing process of the first flange 5 and the second flange 6, the outer wall of the inclined part 11 and the inner wall of the flared part 9 are attached to and squeeze the sealing rubber ring 14, thereby preventing the formation of gaps between the sealing element 4 and the oil pipe body 1 and causing leakage. The sealing element 4 is used to achieve a sealing effect while satisfying the rapid disassembly and assembly of the oil pipe body 1 and the oil pipe joint 2, which is practical.

[0026] The nozzle 3 and the oil pipe connector 2 are connected by a fixing nut 17. The fixing nut 17 is threaded to the oil pipe connector 2. The fixing nut 17 has a first abutment part 18, and the nozzle 3 has a second abutment part 19. The first abutment part 18 abuts against the second abutment part 19. Tightening the fixing nut 17 causes the second abutment part 19 to gradually move closer to the oil pipe connector 2 through the first abutment part 18, thereby connecting the nozzle 3 and the oil pipe connector 2. The end of the oil pipe connector 2 that connects to the nozzle 3 has a third sealing groove 20. A sealing ring 21 is installed in the third sealing groove 20. The sealing ring 21 seals the connection between the nozzle 3 and the oil pipe connector 2 to prevent leakage.

[0027] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
