Technical Field
[0001] The utility model relates to the technical field of mechanical rotating structures, in particular to a multi-segment independent rotating kit and a towel rack with the multi-segment independent rotating kit. Background Art
[0002] Most of the common towel racks on the market at present adopt a fixed structure or a single rotating structure. Although this structure is simple and easy to use, it has certain limitations in the use process. For example, in a relatively narrow space environment, users may need to frequently adjust the position or angle of the towel rack to adapt to different use scenarios. The traditional fixed structure cannot meet such requirements, and although the single rotating structure can provide a certain degree of angle adjustment, it is very difficult to store multiple towels. A few towel racks are provided with multiple rotatable support rods to respectively support multiple towels. Among them, the multiple support rods are simply separated by connecting pieces, and when the user rotates the support rods during use, friction will be generated on the connecting pieces, which will in turn drive the adjacent support rods to rotate, affecting the stability of use and the user experience. Summary of the Utility Model
[0003] The utility model aims to at least solve one of the technical problems existing in the prior art. For this reason, the utility model provides a multi-segment independent rotating kit, which realizes the independent adjustment of each rotating sleeve on the towel rack, enhances the flexibility; at the same time, the circumferential limiting structure effectively prevents the mutual interference between adjacent sleeves, improves the stability of the device and the user experience; in addition, the simple installation method and the space optimization design further improve the practicability and market competitiveness of the product.

[0006] A connecting column;
[0007] A plurality of rotating sleeves, rotatably connected to the connecting column, and the plurality of rotating sleeves are arranged at intervals along the central line direction of the connecting column;
[0008] A limiting sleeve, installed on the connecting column, the limiting sleeve is arranged between adjacent rotating sleeves, both ends of the limiting sleeve are respectively connected to adjacent rotating sleeves, and a circumferential limiting structure is arranged between the limiting sleeve and the connecting column to limit the rotation of the limiting sleeve.
[0009] The multi-segment independent rotation kit according to the present utility model has at least the following beneficial effects: By arranging a plurality of rotating sleeves at intervals along the central axis direction of the connecting column and enabling them to rotate independently, users can individually adjust the angle of each rotating sleeve according to actual needs to adapt to the towel hanging requirements of different sizes and quantities. Moreover, the limiting sleeve is arranged between adjacent rotating sleeves and is connected to the rotating sleeves at both ends. At the same time, a circumferential limiting structure is provided between the limiting sleeve and the connecting column, effectively preventing the rotation of the limiting sleeve itself and avoiding the associated rotation of other rotating sleeves caused by the adjustment action of one rotating sleeve, thereby ensuring that each rotating sleeve can be maintained at the required position after adjustment, enhancing the stability and reliability of the entire device. It not only reduces the redundant components that may appear in the traditional design, making the overall structure more compact and reasonable, but also greatly improves the user experience, enabling the product to be used in various environments, meeting the different needs of users for towel storage, and having a broad market application prospect.
[0010] For the multi-segment independent rotation kit according to some embodiments of the present utility model, the circumferential limiting structure includes a clamping portion and a clamping groove. The clamping portion is arranged on the connecting column, and the clamping groove is arranged on the inner side of the limiting sleeve. The clamping portion is fixedly clamped with the clamping groove.
[0011] For the multi-segment independent rotation kit according to some embodiments of the present utility model, along the axial direction of the limiting sleeve, the clamping groove is arranged to be wider at both ends than in the middle.
[0012] For the multi-segment independent rotation kit according to some embodiments of the present utility model, a first limiting block and a second limiting block are arranged at intervals along the circumferential direction on the inner side of the limiting sleeve, and the clamping portion is adapted to move between the first limiting block and the second limiting block.
[0013] For the multi-segment independent rotation kit according to some embodiments of the present utility model, there are two clamping grooves, and there are also two first limiting blocks and two second limiting blocks. The two first limiting blocks are arranged opposite to each other, and the side walls on the opposite sides of the two first limiting blocks form one clamping groove; the two second limiting blocks are arranged opposite to each other, and the side walls on the opposite sides of the two second limiting blocks form the other clamping groove.
[0014] For the multi-segment independent rotation kit according to some embodiments of the present utility model, the clamping portion is of a flat structure.
[0015] According to the multi-section independently rotating kit described in some embodiments of the utility model, the connecting column also includes a plurality of first extension parts and a plurality of second extension parts, the first extension parts, the clamping parts and the second extension parts are arranged alternately in sequence, the first extension parts and the second extension parts are both cylindrical, and the outer diameters of the first extension parts and the second extension parts are smaller than the maximum outer diameter of the clamping parts.
[0016] According to the multi-section independent rotating kit described in some embodiments of the utility model, along the center line direction of the limiting sleeve, the two ends of the limiting sleeve are respectively provided with a first sleeve connecting portion and a second sleeve connecting portion, and the adjacent rotating sleeves are respectively rotatably sleeved on the first sleeve connecting portion and the second sleeve connecting portion.
[0017] According to the multi-stage independent rotation kit described in some embodiments of the present invention, the outer diameter of the first sleeve connection part and the outer diameter of the second sleeve connection part are gradually reduced along the side away from the center of the limiting sleeve to guide the installation of the rotating sleeve.
[0018] The towel rack according to the utility model comprises the multi-section independent rotation kit according to the utility model.
[0019] The towel rack of the utility model has at least the following beneficial effects: firstly, due to the design concept of multi-stage independent rotation, each rotating sleeve can independently adjust the angle, which means that the user can flexibly adjust the hanging position of each towel according to actual needs. This flexibility is particularly important for families with limited space because it allows users to optimize the storage layout according to specific circumstances, such as the number, size or personal preference of towels;
[0020] Secondly, the circumferential limit structure between the limit sleeve and the connecting column ensures that each rotating sleeve can remain in the specified position after adjustment, and will not be offset due to slight external contact or gravity. This stable structural design not only improves the durability of the product, but also reduces the inconvenience that users may encounter during use, such as towels slipping or sleeves accidentally rotating.
[0021] Furthermore, the design of the clamping part and the clamping groove and the application of the flat structure not only simplify the connection between components, but also improve the stability of the entire device. This design makes the product more efficient during the production and assembly process, and also facilitates the user's subsequent maintenance and cleaning work, reducing the cost of use;
[0022] In addition, the tapered first sleeve portion and the second sleeve portion help guide the correct installation of the rotating sleeve, reducing the error rate during installation, and also provide better positioning support for the rotating sleeve, ensuring smooth operation during use. This humanized design takes into account the actual operating habits of users and makes the product easier to use;
[0023] Finally, by optimizing the structure of the connecting column and adopting an alternating arrangement of multiple first extension parts and second extension parts, not only the overall strength of the structure is ensured, but also unnecessary friction and interference are avoided by reducing the diameter of non-essential parts. Such a design not only improves the aesthetics of the product, but also makes the entire device more compact, saving space;
[0024] In summary, through the integration of multiple technological innovations, the towel rack is not only more stable and reliable in structure, but also more user-friendly and convenient in terms of the usage experience. These improvements make the product more competitive in the market, better meeting various needs of users for towel storage, and reflecting the designer's attention to details and high emphasis on user experience.

[0041] Most of the common towel racks on the market at present adopt a fixed structure or a single rotating structure. Although this structure is simple and easy to use, it has certain limitations in the process of use. For example, in an environment with relatively narrow space, users may need to frequently adjust the position or angle of the towel rack to adapt to different usage scenarios. The traditional fixed structure cannot meet such requirements, and although the single rotating structure can provide a certain degree of angle adjustment, it is very difficult to use when storing multiple towels. A few towel racks are provided with multiple rotatable support rods to respectively support multiple towels. Among them, the multiple support rods are simply separated by connecting pieces, and when the user rotates the support rods during use, friction will be generated on the connecting pieces, which will in turn drive the adjacent support rods to rotate, affecting the stability of use and the user experience.
[0042] Therefore, as Figures 1 to 4 shown, the multi-segment independent rotation kit proposed by the present utility model includes a connecting column 100, a limiting sleeve 300 and a plurality of rotating sleeves 200. Among them, the limiting sleeve 300 is installed on the connecting column 100, and the rotating sleeve 200 is rotatably connected to the connecting column 100 through the limiting sleeve 300, and the plurality of rotating sleeves 200 are arranged at intervals along the center line direction of the connecting column 100. Specifically, the limiting sleeve 300 is arranged between adjacent rotating sleeves 200, and both ends of the limiting sleeve 300 are respectively connected to the adjacent rotating sleeves 200. A circumferential limiting structure is arranged between the limiting sleeve 300 and the connecting column 100 to limit the rotation of the limiting sleeve 300. It should be noted that by arranging the plurality of rotating sleeves 200 at intervals along the center line direction of the connecting column 100 and enabling them to rotate independently, users can adjust the angle of each rotating sleeve 200 separately according to actual needs to adapt to the hanging requirements of towels of different sizes and quantities; moreover, the limiting sleeve 300 is arranged between adjacent rotating sleeves 200, and its two ends are connected to the rotating sleeves 200. At the same time, a circumferential limiting structure is arranged between the limiting sleeve 300 and the connecting column 100, effectively preventing the rotation of the limiting sleeve 300 itself, avoiding the associated rotation of other rotating sleeves 200 caused by the adjustment action of one rotating sleeve 200, thereby ensuring that each rotating sleeve 200 can maintain the required position after adjustment, enhancing the stability and reliability of the entire device, not only reducing the possible redundant components in the traditional design, making the overall structure more compact and reasonable, but also greatly improving the user experience, enabling the product to be used in a variety of environments, meeting the different needs of users for towel storage, and having a wide market application prospect.
[0043] Refer to again Figures 1 to 4, in some embodiments of the present utility model, the circumferential limiting structure includes a clamping portion 120 and a clamping groove 301. The clamping portion 120 is provided on the connecting column 100, and the clamping groove 301 is provided on the inner side of the limiting sleeve 300. The clamping portion 120 is fixedly connected with the clamping groove 301. This method not only simplifies the assembly process but also ensures the fixation of the limiting sleeve 300 relative to the connecting column 100, thereby avoiding the situation where the limiting sleeve 300 rotates together with the rotating sleeve 200 and enhancing the structural stability. This design enables each rotating sleeve 200 to maintain a set position after adjustment, improving the reliability of the device and the user experience. Further, in some embodiments of the present utility model, along the axial direction of the limiting sleeve 300, the clamping groove 301 is wider at both ends than in the middle, making it easier to align and install during the assembly process. At the same time, it provides a larger tolerance range, allowing the connecting column 100 to move freely within a certain range without affecting the structural integrity. This design not only improves the assembly efficiency but also enhances the impact resistance and durability of the device, making the product more stable during use. Moreover, the two ends of the limiting sleeve 300 are symmetrically arranged, enabling it to be assembled and used without considering the front and back, with good versatility.
[0044] Specifically, in some embodiments of the present utility model, as Figures 2 to 4 shown, the first limiting block 310 and the second limiting block 320 are arranged at intervals along the circumferential direction on the inner side of the limiting sleeve 300. The clamping portion 120 is adapted to move between the first limiting block 310 and the second limiting block 320, which can effectively limit the movement range of the clamping portion 120 of the connecting column 100 inside the limiting sleeve 300, avoiding the problem of structural instability caused by excessive rotation, further improving the reliability and service life of the device, making the rotating sleeve 200 more stable during use, and reducing friction and wear caused by excessive rotation. In some assembly applications, when the limiting sleeve 300 is sleeved on the connecting column 100 and the clamping portion 120 is not directly connected with the clamping groove 301, at this time, the clamping portion 120 moves between the first limiting block 310 and the second limiting block 320, that is, the rotation angle of the limiting sleeve 300 is restricted. In further assembly, the user rotates the limiting sleeve 300 to make the clamping portion 120 snap into the clamping groove 301, completing the installation and fixation of the limiting sleeve 300 and the connecting column 100. Referring again to Figure 1In some embodiments of the utility model, along the center line direction of the limiting sleeve 300, the two ends of the limiting sleeve 300 are respectively provided with a first sleeve connection portion 330 and a second sleeve connection portion 340, and the adjacent rotating sleeves 200 are respectively rotated and sleeved on the first sleeve connection portion 330 and the second sleeve connection portion 340. The arrangement of the first sleeve connection portion 330 and the second sleeve connection portion 340 facilitates the installation and disassembly of the rotating sleeve 200, and also provides a reliable support point for the rotating sleeve 200, making it more stable during use and not easy to fall off or loosen. This design simplifies the user's operating steps and improves the user experience. In specific assembly applications, the rotating sleeve 200 and the limiting sleeve 300 are successively inserted into the connecting column 100 to complete the preliminary assembly, and then the limiting sleeve 300 is rotated to a position where it is clamped and fixed with the connecting column 100. Thereafter, multiple rotating sleeves 200 can rotate relatively independently without interfering with each other. Optionally, the outer diameters of the first sleeve portion 330 and the second sleeve portion 340 are gradually reduced along the side away from the center of the limiting sleeve 300 to guide the installation of the rotating sleeve 200. This design helps to guide the correct installation of the rotating sleeve 200, reduces the possibility of installation errors, and also facilitates the positioning of the rotating sleeve 200, making it more stable during use and reducing the failure rate caused by improper installation.
[0045] Refer to Figures 2 to 4 In some embodiments of the utility model, there are two clamping grooves 301, two first limiting blocks 310 and two second limiting blocks 320, the two first limiting blocks 310 are arranged opposite to each other, and the side walls of the two first limiting blocks 310 on the opposite side form a clamping groove 301; the two second limiting blocks 320 are arranged opposite to each other, and the side walls of the two second limiting blocks 320 on the opposite side form another clamping groove 301. The overall structure is simple and makes full use of the first limiting blocks 310 and the second limiting blocks 320. It is easy to understand that the first limiting blocks 310 and the second limiting blocks 320 of the cross-symmetrical structure can form two vertically arranged clamping grooves 301, which not only enhances the symmetry and aesthetics of the structure, but also provides a more solid limiting effect. In addition, it ensures that the rotating sleeve 200 is fixed in position after adjustment, reduces shaking and noise during use, and improves the stability of the overall device. Optionally, the clamping portion 120 is a flat structure, which helps to increase the contact area between the connecting column 100 and the limiting sleeve 300, thereby enhancing the fixing effect. In addition, the flat structure can also prevent the connecting column 100 from unnecessary rotation in the limiting sleeve 300, further ensuring the stability and service life of the structure, so that the product can still maintain good performance during long-term use.
[0046] Refer to Figure 3, in some embodiments of the present utility model, the connecting column 100 includes a plurality of first extension portions 110 and a plurality of second extension portions 130. The first extension portions 110, the clamping portions 120, and the second extension portions 130 are arranged alternately in sequence. Both the first extension portions 110 and the second extension portions 130 are cylindrical, and the outer diameters of the first extension portions 110 and the second extension portions 130 are smaller than the maximum outer diameter of the clamping portions 120. This not only ensures the strength of the overall structure but also avoids interference with the rotating sleeve 200 or other components by reducing the outer diameters of the first extension portions 110 and the second extension portions 130. This design makes the entire device lighter and easier to install while maintaining strength, and at the same time improves the assembly efficiency.
[0047] Further referring to Figure 5 , the towel rack according to an embodiment of the present utility model includes a multi-section independent rotating kit according to an embodiment of the present utility model. Among them, a support rod 210 is connected to the outer wall of the rotating sleeve 200. The support rod 210 extends horizontally and is adapted to support towels. Optionally, the support rod 210 is integrally connected to the rotating sleeve 200.
[0048] For the towel rack according to an embodiment of the present utility model, by adopting the multi-section independent rotating kit according to an embodiment of the present utility model, first of all, due to the design concept of multi-section independent rotation, each rotating sleeve 200 can be independently adjusted in angle, which means that the user can flexibly adjust the hanging positions of each towel according to actual needs. This flexibility is particularly important for families with limited space because it allows the user to optimize the storage layout according to specific situations, such as the number, size of the towels, or personal preferences;
[0049] Secondly, the circumferential limiting structure between the limiting sleeve 300 and the connecting column 100 ensures that each rotating sleeve 200 can be maintained at a specified position after adjustment and will not shift due to slight external touches or gravity. This stable structural design not only improves the durability of the product but also reduces the inconveniences that the user may encounter during use, such as towel slipping or accidental rotation of the sleeve;
[0050] Furthermore, the design of the clamping portion 120 and the clamping groove 301 and the application of the flat structure not only simplify the connection between components but also improve the stability of the entire device. This design makes the product more efficient in the production and assembly process, and at the same time is convenient for the user's later maintenance and cleaning work, reducing the use cost;
[0051] In addition, the tapered first socket part 330 and second socket part 340 help to guide the correct installation of the rotating sleeve 200, reducing the error rate during the installation process. At the same time, they also provide better positioning support for the rotating sleeve 200, ensuring smooth operation during use. This user-friendly design takes into account the actual operating habits of users, making the product easier to use;
[0052] Finally, by optimizing the structure of the connecting column 100 and adopting an alternating arrangement of multiple first extension parts 110 and second extension parts 130, not only the overall strength of the structure is ensured, but also unnecessary friction and interference are avoided by reducing the diameter of non-essential parts. Such a design not only improves the aesthetics of the product, but also makes the entire device more compact, saving space;
[0053] In summary, through the integration of multiple technological innovations, the towel rack is not only more stable and reliable in structure, but also more user-friendly and convenient in terms of the user experience. These improvements make the product more competitive in the market, better meeting the various needs of users for towel storage, and reflecting the designer's attention to details and high emphasis on the user experience.
[0054] Other components and operations of the towel rack according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail here.
[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
