Description

Technical Field

[0001] This application relates to the field of faucet technology, and in particular to a rotating component for a faucet. Background Technology

[0002] To enable multi-angle and multi-functional water dispensing, faucets, especially those with curved pipes, typically require a rotating component between the water outlet and the main body.

[0003] In existing technologies, a common rotating solution integrates the water pipe and the rotating structure into one unit. A common approach is to directly connect the inlet end of the water outlet component to the main component via a bushing. This causes the entire weight and operating torque of the water outlet component to act directly on the rotating seal, which can easily lead to seal wear and leakage over long-term use. Another approach uses a complex universal ball joint structure, which, while achieving multi-directional rotation, results in a tortuous water flow channel, high water resistance, numerous parts, and high assembly and manufacturing costs. Therefore, there is room for further improvement. Utility Model Content

[0004] This application proposes a rotating assembly for a water tap. The rotating assembly transmits water flow while bearing weight and rotating, and also possesses multiple properties such as sealing, load-bearing capacity, wear resistance, and low friction.

[0005] Specifically, this rotating assembly separates the two major functions of "rotation support" and "water passage connection" by setting up a "rotation shaft" specifically for water passage and a "rotation component" responsible for load-bearing rotation. This assembly achieves functional separation and component specialization, thereby fundamentally solving the problems of easy seal damage, rotation jamming and short life caused by functional coupling in traditional designs. At the same time, the structure is simple and easy to manufacture and optimize.

[0006] The rotating assembly for a water tap provided in this application adopts the following technical solution: A rotating assembly for a water tap, the water tap including a main body assembly and a water outlet assembly, the rotating assembly including a rotating shaft disposed between the main body assembly and the water outlet assembly, a rotating element rotatably connected to the rotating shaft, the rotating shaft being fixedly connected to the main body assembly and communicating with its internal water flow channel, the water outlet assembly being axially inserted into the rotating shaft and communicating with its internal water flow channel, and the water outlet assembly being fixedly connected to the rotating element.

[0007] By adopting the above technical solution, when installing the rotating component, firstly, the rotating shaft is fixedly installed on the main component, and the rotating component is rotatably sleeved on the rotating shaft. Then, the water outlet component is fixedly connected to the rotating component, and its inlet end is axially inserted into the outlet end of the rotating shaft. By separating the two major functions of "rotation support" and "water passage connection," specifically by establishing a "rotating shaft" specifically for water passage and a "rotating component" responsible for load-bearing rotation, this component achieves functional separation and component specialization. This fundamentally solves the problems of easy seal damage, rotation jamming, and short lifespan caused by functional coupling in traditional designs. At the same time, the structure is simple, easy to manufacture and optimize, so that the water passage connection mainly bears water pressure rather than torsional friction, resulting in a longer lifespan and more reliable sealing. The rotation function is undertaken by the specially optimized rotating component, making rotation more flexible. The structure is simple and clear, with each component performing its own function.

[0008] Preferably, the rotating shaft has a rotating groove, the rotating component is located in the rotating groove, and the rotating component has an opening for installation.

[0009] By adopting the above technical solution, on the one hand, the rotating groove provides precise accommodation and movement space for the rotating component, effectively restricting its degrees of freedom other than the direction of rotation, allowing it to only perform pure rotation. This design is not only simple in structure but also easy to assemble. On the other hand, the rotating groove provides a clear and reliable center of rotation, thereby ensuring the purity and accuracy of the rotational action.

[0010] Preferably, the water outlet component has a bushing groove, which cooperates with the main component.

[0011] By adopting the above technical solution, the rotating component acts as the first fulcrum supporting the water outlet assembly, bearing part of the torque; the main component acts as the second fulcrum, providing radial support and ensuring smooth rotation. In this structure, the water outlet assembly can rotate around the axis of the rotating shaft, achieving directional adjustment. The joint constraint of the water outlet assembly by the rotating component and the main component greatly enhances the structural stability and anti-shaking ability, effectively solving the problem of loosening and swaying in single-point support structures. Furthermore, the rotation function is undertaken by the rotating component and the main component, while the sealing function is undertaken by the subsequent plug-in sealing structure; each component performs its specific function, improving overall reliability and service life. Moreover, the axial plug-in connection between the water outlet assembly and the rotating shaft naturally ensures the basic alignment of the rotation center with the water channel center, reducing the risk of uneven wear and leakage from the design stage.

[0012] Preferably, the main body component is provided with a wear-resistant bushing, and the bushing groove cooperates with the wear-resistant bushing.

[0013] By adopting the above technical solution, the bushing groove wraps around the wear-resistant bushing, forming a second radial support point, which further constrains the water outlet component and prevents it from wobbling radially. Together with the rotating parts, it forms a "double support point" structure for the water outlet component, which greatly enhances the anti-wobbling ability, makes the faucet feel more solid and high-end, and solves the common problems of wobbling and looseness in cheap faucets.

[0014] Preferably, the rotating component is connected to the screw of the water outlet assembly.

[0015] By adopting the above technical solution, the screw undertakes the connection between the rotating parts and the water outlet assembly, providing the main connecting force for the structure.

[0016] Preferably, the rotating component has a reinforcing protrusion at the connection point, and the water outlet assembly has a reinforcing groove for engaging with the reinforcing protrusion.

[0017] By adopting the above technical solution, the protrusions and grooves form an interlocking structure, which has the functions of anti-rotation, anti-shear, and positioning. This interlocking structure significantly improves the connection strength and can effectively avoid loosening of the connection or stripping of bolts due to long-term forward and reverse rotation, thereby enhancing the rigidity and reliability of the structure.

[0018] Preferably, the water outlet assembly includes an adapter and a connecting part for engaging with the free end of the water outlet faucet.

[0019] By adopting the above technical solution, a good support can be provided for the free end of the water tap.

[0020] Preferably, the rotating shaft has a water outlet groove at its axial end, and the water outlet assembly has a corresponding water inlet protrusion channel, which is inserted into the water outlet groove to achieve water passage connection.

[0021] By adopting the above technical solution, the water path is connected from the rotating shaft to the outlet assembly. This structure has significant advantages: it is simple and direct, with a short water path, resulting in low water resistance. Furthermore, the plug-in connection method ensures that the water path connection remains stable and reliable even during rotation.

[0022] Preferably, a sealing ring is provided on the water inlet protrusion channel.

[0023] By adopting the above technical solution, the sealing ring is compressed between the inlet protruding channel and the inner wall of the outlet groove, thus forming a static seal. This static seal structure effectively prevents water leakage from the connector. Simultaneously, due to the good alignment of the outlet assembly and the rotating shaft, the sealing ring experiences uniform wear during use. Therefore, the sealing life of the sealing ring is significantly extended, effectively solving the common problem of water leakage at the connector of rotating faucets.

[0024] Preferably, the wear-resistant bushing is made of nylon.

[0025] By adopting the above technical solution, the advantages of nylon materials can be fully utilized. Nylon material itself has self-lubricating and wear-resistant properties, and its smooth inner wall further reduces the coefficient of friction. This characteristic allows rotational movements to maintain a smooth and quiet effect over a long period of time. In addition, nylon material also has the advantages of corrosion resistance and low cost, making it very suitable for this application scenario.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By establishing a dedicated "rotating shaft" for water flow and a "rotating component" for load-bearing rotation, this assembly achieves functional separation and component specialization. This fundamentally solves the problems of easy seal damage, rotation jamming, and short lifespan caused by functional coupling in traditional designs. At the same time, the structure is simple, easy to manufacture and optimize, and the water connection mainly bears water pressure rather than torsional friction, resulting in a longer lifespan and more reliable sealing. The rotation function is undertaken by the specially optimized rotating component, making rotation more flexible. The structure is simple and clear, with each component performing its own function. 2. By setting rotating parts and wear-resistant bushings to form a double-support structure, the stability and anti-shaking ability of the water outlet component are significantly enhanced, effectively solving the problem of easy loosening and shaking of single-point support; 3. By separating the rotation function from the sealing function, each component performs its own function, which improves the overall reliability and service life. At the same time, the axial plug design ensures that the rotation center is aligned with the water channel center, reducing the risk of uneven wear and leakage. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0030] This application discloses a rotating assembly for a water tap.

[0031] Reference Figures 1-9 The faucet includes a main body assembly and a water outlet assembly. The rotating assembly includes a rotating shaft 3 and a rotating component 4. The main body assembly includes a housing 1. The water outlet assembly includes an adapter 2. The rotating shaft 3 is inserted into and partially housed within the housing 1. The rotating shaft 3 is connected to the internal water flow channel of the main body assembly. The rotating shaft 3 and the rotating component 4 are rotatably connected. The adapter 2 is sleeved and fixedly connected to the rotating component 4. The adapter 2 is axially inserted into the rotating shaft 3 and connected to its internal water flow channel.

[0032] When installing the rotating assembly, firstly, the rotating shaft is fixedly installed on the main assembly, and the rotating component is rotatably fitted onto the rotating shaft. Then, the water outlet assembly is fixedly connected to the rotating component, with its inlet end axially inserted into the outlet end of the rotating shaft. By separating the two main functions of "rotation support" and "water passage connection," specifically by establishing a "rotating shaft" dedicated to water passage and a "rotating component" responsible for load-bearing rotation, this assembly achieves functional separation and component specialization. This fundamentally solves the problems of easy seal damage, rotation jamming, and short lifespan caused by functional coupling in traditional designs. At the same time, the structure is simple, easy to manufacture and optimize, and the water passage connection mainly bears water pressure rather than torsional friction, resulting in a longer lifespan and more reliable sealing. The rotation function is undertaken by the specially optimized rotating component, making rotation more flexible. The structure is simple and clear, with each component performing its own function.

[0033] Furthermore, in this embodiment, the adapter 2 is also rotatably connected to the housing 1.

[0034] A wear-resistant bushing 5 is interference-fitted to the upper side of the housing 1. The inner wall of the wear-resistant bushing 5 is smooth, and the housing 1 serves as the basic frame of the entire assembly. The interference fit ensures that the wear-resistant bushing 5 is firmly fixed in the housing 1, preventing it from rotating or falling off with the water outlet assembly. This robust assembly method effectively avoids problems such as loosening, abnormal noise, or accelerated wear of the bushing during long-term use, thereby ensuring the long-term stability of the product.

[0035] The rotating shaft 3 is partially inserted and bolted into the housing 1. The lower outer diameter of the rotating shaft 3 is larger than the upper inner diameter. The lower outer diameter of the rotating shaft 3 matches the inner diameter of the housing 1. The upper part of the rotating shaft 3 has a rotating groove 31 for cooperating with the rotating part 4. The upper part of the rotating shaft 3 has a stepped channel 321 in the axial direction. The upper inner diameter of the stepped channel 321 is larger than the lower inner diameter of the stepped channel 321. The lower part of the rotating shaft 3 has an offset channel 322 offset from the axis position. The offset channel 322 is connected to the stepped channel 321. The stepped channel 321 and the offset channel 322 together form a water outlet groove 32.

[0036] The rotating component 4 has an opening 41 on its side wall, allowing it to deform and fit into the rotating groove 31 of the rotating shaft 3. This enables the rotating component 4 to be rotatably connected to the rotating shaft 3. The rotating groove 31 provides precise accommodation and movement space for the rotating component 4, effectively restricting its degrees of freedom except for the direction of rotation, ensuring that the rotating component 4 can only perform pure rotation. This design is not only simple in structure but also easy to assemble. Furthermore, the rotating groove 31 provides a clear and reliable center of rotation, thus ensuring the purity and accuracy of the rotational motion.

[0037] The adapter 2 includes an adapter portion 21 and a connecting portion 22. The connecting portion 22 is integrally formed with the outer wall of the adapter portion 21, and the end of the connecting portion 22 away from the adapter portion 21 is hook-shaped, so that the connecting portion 22 can mate with the outer wall of the bend at the free end of the faucet outlet. The lower outer diameter of the adapter portion 21 is larger than the upper outer diameter of the adapter portion 21. The adapter portion 21 includes an upper adapter portion 211 for connecting with other parts of the water outlet assembly, a lower adapter shell 212 for mates with the housing 1, and a water inlet protrusion channel 213 for inserting into the rotating shaft 3. The upper adapter portion 211 has an upper stepped groove in the axial direction, and the lower end of the upper stepped groove has a thread. The water inlet protrusion channel... The outer wall of 213 is provided with a sealing groove for cooperating with the sealing ring 216. The inner diameter of the upper part of the water inlet protrusion channel 213 is smaller than the inner diameter of the lower part of the upper stepped groove. At the same time, the inner diameter of the lower part of the water inlet protrusion channel 213 is larger than the inner diameter of the upper part of the water inlet protrusion channel 213. A cavity that can cooperate with the rotating shaft 3 and the rotating part 4 is formed between the water inlet protrusion channel 213 and the lower adapter shell 212. The outer wall of the water inlet protrusion channel 213 is provided with a sealing ring 216, so that the lower end face of the water inlet protrusion channel 213 is higher than the lower end face of the lower adapter shell 212. The lower outer wall of the lower adapter shell 212 is provided with a bushing groove 215, and the adapter part 21 is bolted to the rotating part 4.

[0038] The other components of the main body and the water outlet are common components in the prior art, so they will not be described in detail here.

[0039] During assembly, the wear-resistant bushing 5 is first pressed into the housing 1, ensuring its upper end and inner wall fit tightly against the housing 1. Then, the rotating shaft 3 is placed inside the housing 1 and secured with axial bolts. Next, the rotating component 4 is sleeved or clamped into the rotating groove 31 of the rotating shaft 3, forming a rotational fit. Finally, the adapter 2 is inserted axially into the rotating shaft 3, connecting it to the rotating component 4, while simultaneously ensuring that the bushing groove 215 on the outer wall of the adapter 2 mates with the wear-resistant bushing 5.

[0040] After assembly, the rotating shaft 3 serves as the fixed core component, providing both structural support and a water supply channel. The rotating component 4 acts as the first fulcrum, bearing part of the torque during rotation; the wear-resistant bushing 5 acts as the second fulcrum, providing radial support for the adapter 2 and ensuring smooth rotation. Thus, the adapter 2 can rotate stably around the axis of the rotating shaft 3, achieving adjustment of the water outlet direction. This dual-fulcrum structure of "rotating component 4 + wear-resistant bushing 5" jointly constrains the degree of freedom of motion of the adapter 2, significantly improving the overall structure's anti-sway capability and stability, fundamentally addressing the loosening problem commonly found in single-point support structures.

[0041] Furthermore, this structure achieves a reasonable separation of functional modules: the rotation function is shared by the rotating component 4 and the wear-resistant bushing 5, while the sealing function is completed by an independent plug-in sealing structure. The clear division of labor among the components helps to improve reliability and extend service life. The adapter 2 and the rotating shaft 3 adopt an axial plug-in connection, which naturally ensures that the rotation center is aligned with the center of the water channel, reducing the risk of leakage due to uneven wear from the structural design.

[0042] When the adapter 2 is fitted with the housing 1, its bushing groove 215 wraps around the wear-resistant bushing 5, forming an effective radial constraint, further enhancing the anti-shaking performance, making the faucet operation feel more solid and stable, and overcoming the looseness phenomenon commonly found in traditional low-priced faucets.

[0043] Regarding waterway connectivity, this structure achieves a smooth transition from the fixed component (rotating shaft 3) to the moving component (adapter 2). Its plug-in connection method is simple in structure and has a short flow channel, which helps to reduce water resistance and maintain the continuous stability of the waterway connection during rotation.

[0044] Regarding sealing, the sealing ring 216, located on the inlet protrusion channel 213, forms a static seal under pressure when in contact with the inner wall of the rotating shaft 3, effectively preventing leakage at the interface. Thanks to its well-aligned design, the sealing ring 216 wears evenly, significantly extending its sealing life and reliably solving the common leakage problem at the interface of rotating faucets.

[0045] Furthermore, in this embodiment, both ends of the rotating component 4 are arc-shaped curved surfaces. The arc-shaped curved surfaces and the rotating groove 31 form a contact area with low frictional resistance. Firstly, this greatly reduces frictional resistance and contact stress, making the rotation process smoother and less strenuous. Secondly, it effectively reduces wear and increases the service life of the rotating component 4. Overall, both user experience and product durability are significantly improved.

[0046] Furthermore, in this embodiment, the rotating component 4 has a reinforcing protrusion 42 integrally formed near the bolt connection, and the adapter 2 has a reinforcing groove 214 near the bolt connection. The reinforcing groove 214 and the reinforcing protrusion 42 fit together. The bolt bears the main connecting function, providing the main connecting force for the structure. At the same time, the fitting structure of the reinforcing protrusion 42 and the reinforcing groove 214 has the functions of anti-rotation, anti-shear, and positioning. This significantly improves the connection strength, effectively avoiding loosening of the connection or stripping of the bolt due to long-term forward and reverse rotation, thereby enhancing the rigidity and reliability of the structure.

[0047] Furthermore, in this embodiment, the wear-resistant bushing 5 is made of nylon, which fully leverages the advantages of nylon. Nylon itself possesses self-lubricating and wear-resistant properties, and its smooth inner wall further reduces the coefficient of friction. This characteristic allows the rotational motion to maintain a smooth and quiet operation over a long period. In addition, nylon is corrosion-resistant and low-cost, making it highly suitable for this application.

[0048] Furthermore, in this embodiment, the outer wall of the lower adapter shell 212 of the adapter 2 is a smooth cylindrical surface, which directly rotates with the inner hole of the wear-resistant bushing 5. Therefore, the bushing groove 215 does not need to be provided, but providing the bushing groove 215 is still preferred.

[0049] Furthermore, in this embodiment, the rotating component 4 and the water outlet assembly can also be connected by common fixing methods such as bolt connection and screw connection.

[0050] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
