[0026] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0027] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.
[0028] To facilitate understanding, the main implementation concepts of each embodiment of the present invention are first briefly described.
[0029] like Figure 1 As shown, existing technologies in the field of automotive steering system components, particularly the connection between the steering pump oil port 9 and the connector in large vehicles like trucks, have exposed significant problems and limitations. Traditional connection methods primarily rely on a lock nut 3 and an O-ring 2 for sealing and securing. Specifically, the lock nut 3 is screwed directly onto the steering pump oil port 9, while the O-ring 2 is positioned between the two to achieve a sealing effect.
[0030] However, this seemingly simple connection method has serious drawbacks in practical applications. When the lock nut 3 is tightened, the force exerted on the O-ring 2 tends to cause it to rotate. This rotation not only easily causes deformation and wear of the O-ring itself, but can also cause it to be crushed during installation. Once the O-ring 2 is damaged, its sealing performance is significantly compromised, and it can no longer effectively prevent oil leakage.
[0031] Oil leakage is a serious problem for automobiles, especially large vehicles like trucks. It not only affects vehicle operation and can lead to safety hazards such as steering failure, but can also pollute the environment. Furthermore, frequent oil leaks increase vehicle maintenance costs and reduce overall economic efficiency.
[0032] Therefore, to address this significant shortcoming in the prior art, a new connection method between the steering pump oil port 9 and the connector is urgently needed to address the issue of easy damage and oil leakage of the O-ring 2. This new connection method needs to ensure sealing performance while effectively preventing damage to the O-ring 2 during the tightening process, thereby improving the reliability and durability of the entire steering system.
[0033] In summary, the existing connection methods described in the background art are no longer able to meet the practical application requirements of automotive steering system component technology. The fragility and oil leakage of the O-ring 2 not only affect the normal operation and safety of the vehicle, but also increase maintenance costs and the risk of environmental pollution. Therefore, developing a new connection method between the steering pump oil port 9 and the connector that can address these issues is particularly urgent and important.
[0034] The inventors, having discovered the above-mentioned defects in the prior art, have provided a combined joint with adjustable direction. Through a specific structural design, the O-ring 2 will not rotate during the locking process, thereby avoiding the risk of damage due to rotation. Moreover, since the O-ring 2 will not be damaged by extrusion and rotation during locking, its sealing effect is significantly improved, effectively preventing the occurrence of oil leakage.
[0035] Figure 2 This is a schematic structural diagram of a direction-adjustable combined joint according to an embodiment of the present utility model, when the combined joint is not installed on a steering pump; Figure 3 It is a structural schematic diagram of a direction-adjustable combined joint installed on a steering pump according to one embodiment of the utility model.
[0036] like Figures 2 to 3 As shown, according to one embodiment of the utility model, an adjustable direction combination joint is used to be connected to an oil pipe 10, and the adjustable direction combination joint includes: an adjustable direction joint 1, an O-ring 2 and a locking nut 3. A groove is provided at the upper portion of the lower end of the adjustable direction joint 1. The O-ring 2 is arranged in the groove of the adjustable direction joint 1. And the locking nut 3 is screwed on the upper portion of the lower end of the adjustable direction joint 1, thereby pressing the O-ring 2 into the groove. Wherein, the upper end of the adjustable direction joint 1 is used to be connected to the oil pipe 10, and the lower end of the adjustable direction joint 1 is used to be connected to the steering pump (steering pump oil port 9).
[0037] Specifically, the adjustable joint assembly of the present invention is an innovative automotive component specifically designed to securely and flexibly connect a steering pump and a fuel pipe 10. The joint assembly primarily comprises three components: an adjustable joint 1, an O-ring 2, and a locking nut 3. A groove is cleverly defined at the upper portion of the lower end of the adjustable joint 1 to accommodate the O-ring 2. During installation, the O-ring 2 is placed in the groove, and the locking nut 3 is tightened onto the upper portion of the lower end of the adjustable joint 1, thereby firmly pressing the O-ring 2 into the groove and achieving a tight seal. This design allows the upper end of the adjustable joint 1 to flexibly connect to the fuel pipe 10, while the lower end connects to the steering pump. This not only ensures a secure connection but also allows for a range of adjustment to accommodate various installation requirements. For example, in truck steering systems, the relative position of the steering pump and fuel pipe 10 may vary depending on the vehicle model or installation layout. This adjustable joint assembly easily accommodates this, ensuring a secure and flexible steering system connection.
[0038] In one or more embodiments, the adjustable direction joint 1 is L-shaped.
[0039] Specifically, this L-shaped design allows the connector to provide greater flexibility and adaptability when connecting the steering pump and the oil pipe 10. For example, in some truck steering systems, due to spatial constraints, the connection between the steering pump and the oil pipe 10 may need to be made at a certain angle. In such cases, a traditional straight connector may not meet this requirement. However, the L-shaped adjustable connector 1 can easily accommodate this situation, allowing the steering pump and the oil pipe 10 to be tightly connected at the appropriate angle, ensuring the proper functioning of the steering system.
[0040] In one or more embodiments, a first external thread 4 is formed at the lower end of the adjustable direction joint 1 .
[0041] Specifically, the lower end of the connector is provided with a first external thread 4, which allows it to be easily screwed into the corresponding internal threaded hole on the steering pump, achieving a secure connection. This design not only simplifies the installation process but also improves the reliability and sealing of the connection. For example, in a truck's steering system, using this adjustable directional connector 1 with internal and external threads can more conveniently connect the oil pipe 10 to the steering pump. The connection is more secure and less likely to loosen or leak, thus ensuring the normal operation of the steering system.
[0042] In one or more embodiments, the groove, the O-ring 2 and the locking nut 3 are all located above the first external thread 4 of the adjustable direction joint 1 .
[0043] Specifically, this design ensures that the sealing and locking components are not disturbed when the connector is connected to the steering pump, while also facilitating installation and removal. When using this adjustable directional connector 1 in a truck's steering system, the O-ring 2 is first placed into the groove, and then the lock nut 3 is tightened to secure it to the connector. Because these components are located above the first external thread 4, they are not affected when the connector is screwed into the internal thread of the steering pump. This not only ensures a tight and secure connection, but also makes the entire installation process simpler and faster.
[0044] In one or more embodiments, the direction-adjustable combined joint further includes a washer 5 disposed between the direction-adjustable joint 1 and the steering pump.
[0045] Specifically, the design of the adjustable directional joint has been further optimized, with the addition of a gasket 5. This gasket 5 is cleverly positioned between the adjustable directional joint 1 and the steering pump, providing both cushioning and protection. For example, in a truck's steering system, when using this adjustable directional joint 1 with gasket 5, the gasket 5 effectively disperses pressure between the joint and the steering pump, reducing wear and damage caused by direct contact. Simultaneously, the gasket 5 provides an additional seal, preventing oil leakage and ensuring the proper functioning of the steering system. This design not only improves the reliability and durability of the steering system but also extends its service life.
[0046] In one or more embodiments, a second external thread 6 is provided on the upper portion of the lower end of the adjustable direction joint 1 , the upper end of the locking nut 3 is screwed onto the second external thread 6 , and there is a distance between the second external thread 6 and the groove.
[0047] Specifically, the upper portion of the lower end of the adjustable directional joint 1 is cleverly formed with a second external thread 6, and the upper end of the lock nut 3 is designed to be screwed onto this second external thread 6. Importantly, a certain distance is maintained between the second external thread 6 and the groove. This design ensures that the lock nut 3 does not excessively compress the O-ring 2 in the groove when tightened, thereby ensuring the sealing effect and service life of the seal ring. In a truck's steering system, when using this design of the adjustable directional joint 1, the O-ring 2 can be placed in the groove first, and then the lock nut 3 is tightened onto the second external thread 6. Due to the certain distance between the second external thread 6 and the groove, the lock nut 3 does not contact the O-ring 2 in the groove during tightening, avoiding unnecessary pressure and damage to the O-ring 2. This not only ensures a tight and reliable connection between the steering pump and the oil pipe 10, but also effectively extends the service life of the O-ring 2, improving the stability and durability of the entire steering system.
[0048] In one or more embodiments, the upper portion of the locking nut 3 has an internal thread, and the locking nut 3 is screwed onto the second external thread 6 of the adjustable direction joint 1 through the internal thread.
[0049] Specifically, the design of the locking nut 3 is ingenious, featuring internal threads on its upper portion. This allows the locking nut 3 to be easily screwed onto the second external threads 6 of the adjustable directional joint 1 via the internal threads, thereby achieving a secure connection. In a truck's steering system, when connecting the steering pump and oil pipe 10, the O-ring 2 can be placed in the groove of the adjustable directional joint 1, and then the locking nut 3 can be screwed onto the second external threads 6 of the joint via its internal threads. This way, the locking nut 3 firmly presses the O-ring 2 into the groove, ensuring a tight and secure connection. This design not only simplifies the installation process but also improves the efficiency and reliability of the steering system.
[0050] In one or more embodiments, a light hole 7 is opened at the lower portion of the locking nut 3 , and the light hole 7 is used to press the O-ring 2 into the groove of the adjustable direction joint 1 .
[0051] Specifically, a special light hole 7 is designed at the bottom of the locking nut 3. The role of this light hole 7 is very critical. It is used to tightly press the O-ring 2 into the groove of the adjustable directional joint 1 when the locking nut 3 is tightened. This design ensures the sealing of the connection and prevents oil leakage. In the steering system of the truck, when installing the adjustable directional joint 1, the O-ring 2 is first placed in the groove of the joint. Then, the locking nut 3 is tightened so that the light hole 7 at the bottom is aligned with and presses the O-ring 2. In this way, the O-ring 2 is firmly fixed in the groove, ensuring that the connection between the steering pump and the oil pipe 10 is both tight and reliable, thereby improving the working efficiency and safety of the entire steering system.
[0052] In one or more embodiments, the lower portion of the locking nut 3 has a boss 8 , and the boss 8 is used to engage with the washer 5 .
[0053] Specifically, the design of the locking nut 3 has been further optimized, and a boss 8 structure has been specially added to its lower part. The design of this boss 8 is ingenious, and it is mainly used to achieve a snap-fit function with the washer 5. This snap-fit method not only enhances the connection stability between the locking nut 3 and the washer 5, but also improves the sealing and reliability of the entire adjustable direction combined joint. The structure of the boss 8 matches the corresponding groove or opening on the washer 5. When the locking nut 3 is tightened, the boss 8 will be embedded in the groove of the washer 5 or pass through the opening, thereby achieving a firm snap-fit between the two. This snap-fit mechanism effectively prevents the washer 5 from sliding or shifting during operation, ensuring that the washer 5 can always remain in the correct position and play its due buffering and sealing role.
[0054] This design of adjustable directional joint is used in truck steering systems. During installation, the washer 5 is first placed between the adjustable directional joint 1 and the steering pump, and then the lock nut 3 is tightened. As the lock nut 3 is tightened, the boss 8 on its lower portion fits tightly into the groove or opening on the washer 5, achieving a snap-fit connection between the two. This way, even if the vehicle encounters bumps or vibrations during driving, the washer 5 remains stable and will not fall off or shift, thereby ensuring the sealing and reliability of the connection between the steering pump and the oil pipe 10. In addition, this design of the boss 8 and washer 5 snap-fitting simplifies the installation process and improves work efficiency. The operator only needs to place the washer 5 in the designated position and tighten the lock nut 3 to complete the installation, without the need for additional fixing tools or materials. This not only reduces installation costs but also reduces the risk of installation errors and failures caused by improper operation.
[0055] In practical application, the adjustable joint assembly of the present invention includes an adjustable joint 1, a locking nut 3 with a light hole 7, an O-ring 2, and a washer 5. The smooth rod portion of the adjustable joint 1 has a groove into which the O-ring 2 is inserted. The locking nut 3 with a light hole 7 is screwed onto the adjustable joint 1. The light hole 7 of the locking nut 3 with a light hole 7 and the smooth rod of the adjustable joint 1 fit together, and the light hole 7 of the locking nut 3 with a light hole 7 presses against the O-ring 2 in the groove of the smooth rod portion of the adjustable joint 1, thereby achieving a seal between the locking nut 3 with a light hole 7 and the adjustable joint 1. When the assembly joint is connected to the steering pump oil port 9, the lower section of the locking nut 3 with a light hole 7 and the 45° chamfered upper end surface of the steering pump oil port 9 are sealed with a combination washer 5. The adjustable joint 1 and the steering pump oil port 9 are connected by threads. This creates a strong seal between the threads of the lock nut 3 with the light hole 7 and the threads of the directional connector, as well as between the lower section of the lock nut 3 with the light hole 7 and the upper end surface of the steering pump oil port 9, preventing oil leakage caused by the O-ring 2 being squeezed when tightening the nut. The other end of the directional connector 1 is connected to the oil pipe 10.
[0056] In summary, the direction-adjustable combined joint of the present invention has the following beneficial effects:
[0057] 1. The design of the combined joint of the utility model is more reasonable. Through the specific structural design, the O-ring will not rotate during the locking process, thus avoiding the risk of damage due to rotation;
[0058] 2. Since the O-ring will not be damaged by extrusion and rotation when locked, its sealing effect is significantly improved, effectively preventing the occurrence of oil leakage;
[0059] 3. By improving the sealing effect, the combined joint of the utility model effectively avoids the problem of oil leakage, thereby reducing the safety hazards and environmental pollution that may be caused by oil leakage;
[0060] 4. Since the O-ring is not easily damaged, the durability and reliability of the entire combined joint are improved, reducing maintenance costs and replacement frequency.
[0061] 5. The combined connector of the utility model is suitable for various vehicles that require steering system connection, especially heavy vehicles such as trucks, and has broad application prospects and market value.
