DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection.

[0022] Example 1:

[0023] like Figures 1-8 As shown, the present invention provides a shaft for concealing a wiring harness, comprising a first connecting arm 1 and a second connecting arm 2. The first connecting arm 1 is fixedly mounted with a first base plate 3, which is integrally injection-molded with the first base plate 3. The second connecting arm 2 is fixedly mounted with a second base plate 4, which is integrally injection-molded with the second base plate 4. The first base plate 3 is movably connected to the second base plate 4 via a shaft 5, which is provided with a wire hole 6. The first and second connecting arms 1 and 2 are each provided with an assembly cavity 7, a wire groove 8, and a reinforcing rib 9. The assembly cavity 7 is connected to the wire groove 8 via a wire hole 10. A wear-resistant gasket 11 is mounted on the shaft 5, located between the first and second base plates 3 and 4. The wear-resistant gasket 11 is provided with an oiling port 12. The first base plate 3 is provided with a first protrusion 13, and the second base plate 4 is provided with a second protrusion 14. The second protrusion 14 is provided with a stopper 15. Both the first and second base plates 3 and 4 are made of stainless steel. A stopper 16 and a spring washer 17 are fixedly mounted on the shaft 5, and a nut 19 is screwed onto the shaft 5 via a thread 18.

[0024] Through the above technical solution, the first connecting arm 1 of the utility model is fixedly installed with the first substrate 3, the first connecting arm 1 and the first substrate 3 are made of different materials, and the first connecting arm 1 and the first substrate 3 are integrally injection-molded, and the second connecting arm 2 is fixedly installed with the second substrate 4, the second connecting arm 2 and the second substrate 4 are made of different materials, and the second connecting arm 2 and the second substrate 4 are integrally injection-molded. Through the integral injection molding process, the stability of the connection between the connecting arm (1, 2) and the substrate (3, 4) is improved, and at the same time, the rigidity of the overall structure of the connecting arm (1, 2) is enhanced, and the service life of the shaft structure is improved.

[0025] Example 2:

[0026] like Figures 1-8As shown, the first connecting arm 1 and the second connecting arm 2 of the present invention are structurally identical and are both made of plastic. The connecting arm is used to fix the rotating shaft to other structural objects. The first connecting arm 1 and the second connecting arm 2 are both fixedly connected to the base plate by integrated injection molding. Specifically, the first connecting arm 1 is fixedly mounted with the first base plate 3. The first connecting arm 1 and the first base plate 3 are made of different materials, namely stainless steel. The first connecting arm 1 and the first base plate 3 are integrally injection molded, thereby improving the stability of the connection between the first connecting arm 1 and the first base plate 3 and simultaneously improving the rigidity of the first connecting arm 1. The second connecting arm 2 is fixedly mounted with the second base plate 4. The second connecting arm 2 and the second base plate 4 are made of different materials, namely stainless steel. The second connecting arm 2 and the second base plate 4 are integrally injection molded, thereby improving the stability of the connection between the second connecting arm 2 and the second base plate 4 and simultaneously improving the rigidity of the second connecting arm 2. Through the combined and integral injection molding process, the stability of the connection between the connecting arm and the base plate is significantly improved, while also enhancing the rigidity of the connecting arm.

[0027] In practice, the first connecting arm 1 and first base plate 3 are molded using one-piece injection molding. This ensures a seamless joint between the two components, reducing weak points at the connection and enhancing the overall structural stability of the hinge. The same process is also applied between the second connecting arm 2 and second base plate 4, ensuring that the connecting components at both ends of the hinge maintain a secure connection even when subjected to stress. This one-piece injection molding technique not only improves the stability of the connecting components but also increases the rigidity of the hinge structure, making it more durable during use.

[0028] The operating principle of the hinge is that the first base plate 3 is movably connected to the second base plate 4 via a shaft 5, forming the main structure of the hinge. A guide hole 6 is located at the center of the shaft 5. This hole allows the wires to pass from one port to the other, thus concealing the wiring harness. The design of the guide hole 6 ensures that the wires are not squeezed or pulled during the movement of the hinge, thereby maintaining the stability and security of the wiring harness.

[0029] To further enhance the functionality of the shaft, both the first connecting arm 1 and the second connecting arm 2 are provided with an assembly cavity 7, a wire groove 8, and a reinforcing rib 9. A dust cover is installed at the opening of the assembly cavity 7. The assembly cavity 7 facilitates operations such as threading the wiring harness, installing the shaft, and lubricating the shaft. The interior of the assembly cavity 7 is connected to the wire groove 8 via a wire hole 10. The wire groove 8 is used to guide and protect the wires, preventing them from being exposed and damaged during shaft movement. The provision of the reinforcing rib 9 provides additional support and stability for the connection portion of the shaft, further improving the structural strength and durability of the first connecting arm 1 and the second connecting arm 2.

[0030] The wear-resistant gasket 11 of the present invention is mounted on the shaft 5 and is located between the first substrate 3 and the second substrate 4. The main function of the wear-resistant gasket 11 is to prevent direct contact between the first substrate 3 and the second substrate 4, thereby reducing the wear between the two. The application of the wear-resistant gasket 11 can significantly reduce the wear caused by the friction between the two substrates during the operation of the rotating shaft. When the rotating shaft is running, the first substrate 3 and the second substrate 4 will generate friction due to relative movement. This friction will cause material wear and structural damage, thereby shortening the service life of the rotating shaft. By arranging the wear-resistant gasket 11 on the shaft 5, the two substrates can be effectively isolated, avoiding direct contact, thereby reducing the wear caused by friction.

[0031] To further enhance the lubrication of the wear-resistant gasket 11, the gasket is provided with an oiling port 12. The oiling port 12 allows lubricating oil to be applied directly to the contact points between the wear-resistant gasket 11 and the first and second substrates 3 and 4. This design allows the lubricating oil to continuously form a lubricating layer between the wear-resistant gasket 11 and the substrates, thereby reducing wear caused by friction. The use of lubricating oil can effectively reduce the coefficient of friction, making the rotating shaft smoother during operation, reducing energy loss and noise generation. At the same time, the lubricating oil can penetrate into the tiny gaps in the wear-resistant gasket 11, ensuring that the contact surface between it and the substrates remains properly lubricated.

[0032] The first and second base plates 3 and 4 of the present invention are respectively provided with first and second protrusions 13 and 14. These protrusions are designed to enhance the stability and assembly efficiency of the rotating shaft. The first and second protrusions 13 and 14 maintain active contact with the wear-resistant gasket 11. These protrusions not only optimize the assembly process but also reduce the number of components, simplifying manufacturing and maintenance. The first protrusions 13 on the first base plate 3 and the second protrusions 14 on the second base plate 4 are located at the rotating shaft positions and contact the wear-resistant gasket 11. This design ensures that the first and second base plates 3 and 4 maintain an appropriate gap during operation, staggering their positions and allowing the first and second connecting arms 1 and 2 to rotate into an overlapping position. Compared to traditional assembly methods, the use of protrusions significantly reduces the number of assembly components. Traditional methods typically require additional shims to offset the base plates, increasing the number of components required and increasing the complexity of assembly. Using multiple shims not only increases production costs but can also lead to complex assembly operations and inconsistent assembly results. By setting up a raised structure on the substrate, this design can simplify the assembly process while reducing the number of components, thereby improving the overall manufacturing efficiency of the shaft. The provision of the first protrusion 13 and the second protrusion 14 also has another important function, which is to improve the assembly accuracy of the shaft. The raised structure can more accurately control the gap between the first substrate 3 and the second substrate 4, thereby ensuring that the shaft has high stability and smoothness during operation. A limit block 15 is provided on the second protrusion 14. The limit block 15 is used to limit the rotation range of the shaft body to prevent the wiring harness from being broken due to excessive rotation of the shaft.

[0033] The first substrate 3 and the second substrate 4 of the present invention are both made of stainless steel. Stainless steel performs well in the face of moisture, chemicals or other environments that may cause corrosion due to its excellent corrosion resistance. The shaft may be exposed to different environmental factors in actual applications, including humidity, chemical solvents and other corrosive substances. The use of stainless steel can effectively prevent these environmental factors from eroding the substrate, avoiding material degradation and performance degradation caused by corrosion. Stainless steel has high strength and hardness, which makes it perform well when subjected to mechanical loads. The shaft needs to withstand different degrees of force during operation, and the stainless steel substrate can provide sufficient strength to support these loads, thereby reducing deformation and damage to the substrate.

[0034] The shaft 5 of the present invention is fixedly mounted with a limit washer 16 and a spring washer 17. The shaft 5 is connected and fixed with a nut 19 via a thread 18. The function of the limit washer 16 and the spring washer 17 is to provide necessary restrictions and buffering during the operation of the shaft, ensuring that the shaft does not exceed the predetermined rotation range during operation, thereby avoiding potential mechanical damage and damage to the wiring harness. The limit washer 16 functions to limit the rotation range of the shaft. It is used in conjunction with the limit block 15 on the second base plate 4 to form a limiting device. The limit block 15 is designed to control the maximum angle of the shaft during rotation to prevent the shaft from rotating beyond the set range. The contact between the limit washer 16 and the limit block 15 ensures that the rotation of the shaft does not exceed the predetermined limit. This limiting mechanism is particularly important for protecting the shaft and the connected wiring harness. By preventing the shaft from rotating excessively, the limit washer 16 can effectively prevent the wiring harness from being broken or subjected to excessive tension, thereby extending the service life of the wiring harness and reducing failures caused by wiring harness damage. The spring washer 17 plays an important buffering role in the design of the shaft 5. The design of the spring washer 17 enables the shaft to absorb certain impacts and vibrations during rotation, reducing direct collisions between mechanical components. This buffering effect helps to reduce the wear of mechanical components and maintain the smooth operation of the shaft. The spring washer 17 can provide elastic support during the rotation of the shaft to prevent structural damage or instability due to external forces. The nut 19 connected by the thread 18 is responsible for fixing the shaft 5 in the overall structure of the shaft. The installation of the nut 19 enables the shaft 5 to be firmly connected to other components of the shaft, ensuring the overall stability of the shaft. By screwing the thread 18 together, precise tightening and adjustment can be achieved to ensure that the connection between the various components is firm and reliable. The use of the nut 19 improves the assembly accuracy of the shaft and ensures stability during use.
