Technical Field
[0001] This utility model relates to the field of curtain ring technology, specifically to a split curtain ring. Background Technology
[0002] With the upgrading of the home decoration industry and consumers' pursuit of a higher quality of life, the market demand for curtain rings, as a core accessory for curtain hanging and adjustment, continues to expand, showing diverse requirements for functionality, durability, and aesthetics. Currently, most curtain rings on the market adopt a one-piece structure, with materials including plastic, metal, and wood, which can meet basic hanging needs.
[0003] However, the inner and outer rings and connecting structure of traditional integrated curtain rings cannot be separated. During installation, the entire curtain must be threaded through, which is cumbersome and easily scratches the curtain fabric. If a part is damaged, the whole thing needs to be replaced, resulting in material waste. Furthermore, the connecting parts of the inner and outer rings of existing products are mostly in rigid contact, lacking an effective friction-reducing structure. When pulling the curtain, it is easy to cause jamming and skewing, accompanied by obvious friction noise. Especially in special scenarios such as L-shaped or U-shaped windows, the problem of poor transmission is more prominent. Therefore, those skilled in the art provide a split curtain ring to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to provide a split curtain ring to solve the problems mentioned in the background art of the prior art.
[0005] This utility model provides the following technical solution: a split curtain ring, including an outer ring, a connecting component for connecting the inner and outer rings is provided on one side of the inner cavity of the outer ring, an inner ring is provided on the outer surface of the connecting component away from the outer ring, the connecting component includes a connecting post, the connecting post is disposed in the inner cavity on one side of the outer ring, a first inner support ring is fixedly connected to the side of the connecting post near the outer ring, a first limiting ring is fixedly connected to the outer surface of the first inner support ring, a second inner support ring is fixedly connected to the end of the connecting post away from the first inner support ring, and a second limiting ring is fixedly connected to the outer surface of the second inner support ring.
[0006] As a preferred embodiment of the above technical solution, a spindle is slidably connected to the outer surface of the connecting post. The spindle is disposed between the outer ring and the inner ring. The inner cavity of the spindle has several sets of symmetrically arranged connecting grooves, and the connecting post passes through the inner cavity of the spindle via the connecting grooves.
[0007] As a preferred embodiment of the above technical solution, the outer ring includes a first outer ring wall, and a first support ring is fixedly connected to the side of the first outer ring wall away from the inner ring. A plurality of symmetrically arranged first positioning holes are fixedly connected to the center of the inner cavity of the first support ring near the edge, and the first positioning holes are fixedly connected to the outer surface of the connecting post.
[0008] As a preferred embodiment of the above technical solution, the inner ring includes a second ring outer wall, which is disposed on the outer surface of the connecting post away from the outer wall of the first ring. A second support ring is fixedly connected to the outer wall of the second ring away from the outer wall of the first ring. A plurality of symmetrically arranged second positioning holes are fixedly connected to the center of the inner cavity of the second support ring near the edge, and the second positioning holes are fixedly connected to the outer surface of the connecting post.
[0009] As a preferred embodiment of the above technical solution, the outer surfaces of both the first limiting ring and the second limiting ring are provided with a smooth and wear-resistant coating, wherein the smooth and wear-resistant coating is a polytetrafluoroethylene coating with a thickness of 0.1-0.3 mm.

Combined with the limiting effect of the first and second limiting rings, this effectively prevents components from shifting or detaching, ensuring the long-term reliability of the overall structure. Regarding smooth operation, the sliding connection of the connecting post's outer surface to the pivot ball located between the outer and inner rings significantly reduces frictional resistance between components, making the curtains move more smoothly. Its symmetrical connecting grooves within the cavity also ensure precise movement and prevent jamming. In terms of durability and safety, the PTFE wear-resistant coating on the outer surfaces of the first and second limiting rings reduces wear and extends service life.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0015] Please see Figures 1-4 As shown, this utility model provides a technical solution: a split curtain ring, including an outer ring 1. A connecting component 2 for connecting the inner and outer rings 1 is provided on one side of the inner cavity of the outer ring 1. An inner ring 3 is provided on the outer surface of the connecting component 2 away from the outer ring 1. The connecting component 2 includes a connecting post 21, which is located in the inner cavity on one side of the outer ring 1. A first inner support ring 22 is fixedly connected to the side of the connecting post 21 near the outer ring 1. A first limiting ring 23 is fixedly connected to the outer surface of the first inner support ring 22. A second inner support ring 24 is fixedly connected to the end of the connecting post 21 away from the first inner support ring 22. A second limiting ring 25 is fixedly connected to the outer surface of the second inner support ring 24.
[0016] The outer ring 1 is stably connected to one end of the connecting post 21 in the connecting assembly 2 through the first positioning hole 13 on its first support ring 12, while the inner ring 3 is fixed to the other end of the connecting post 21 through the second positioning hole 33 on its second support ring 32, thus realizing the separate assembly of the outer ring 1 and the inner ring 3. The first inner support ring 22 and the first limiting ring 23, and the second inner support ring 24 and the second limiting ring 25 on the connecting post 21 respectively provide support and limit the connection structure from both sides, preventing the outer ring 1 and the inner ring 3 from being separated. During use, the connecting post 21 may detach or shift. At the same time, the pivot ball 26, which is slidably connected to the outer surface of the connecting post 21 and located between the outer ring 1 and the inner ring 3, can rotate freely along the connecting post 21. When the curtain is pulled, it causes the inner ring 3 or the outer ring 1 to move. The pivot ball 26 can reduce the frictional resistance between the outer ring 1 and the inner ring 3 by rotating itself, making the curtain pull smoother. The symmetrical connecting groove 27 in the inner cavity of the pivot ball 26 ensures that it always moves along the axis of the connecting post 21 and avoids shifting.
[0017] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, a spindle ball 26 is slidably connected to the outer surface of the connecting post 21. The spindle ball 26 is located between the outer ring 1 and the inner ring 3. The inner cavity of the spindle ball 26 has several sets of symmetrically arranged connecting grooves 27, and the connecting post 21 passes through the inner cavity of the spindle ball 26 through the connecting grooves 27.
[0018] The pivot ball 26, which is slidably connected to the outer surface of the connecting post 21, plays a crucial role. Located between the outer ring 1 and the inner ring 3, and with several symmetrically arranged connecting grooves 27 penetrating the inner cavity of the pivot ball 26, the pivot ball 26 can move stably with the connecting post 21 as a reference. When the curtain is pulled, causing displacement of the inner ring 3 or the outer ring 1, the pivot ball 26 can slide flexibly along the outer surface of the connecting post 21. Simultaneously, the symmetrically distributed connecting grooves 27 restrict the direction of movement of the pivot ball 26, preventing it from shifting or tilting during sliding. This effectively reduces the frictional resistance between the outer ring 1 and the inner ring 3, making the curtain pulling operation smoother and ensuring the stability and flexibility of the overall transmission of the split curtain ring.
[0019] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the outer ring 1 includes a first ring outer wall 11. A first support ring 12 is fixedly connected to the side of the first ring outer wall 11 away from the inner ring 3. A number of symmetrically arranged first positioning holes 13 are fixedly connected to the center of the inner cavity of the first support ring 12 near the edge, and the first positioning holes 13 are fixedly connected to the outer surface of the connecting post 21.
[0020] The outer wall 11 of the first ring of the outer ring 1 provides basic support for the overall structure. The first support ring 12, which is fixedly connected to the side away from the inner ring 3, not only enhances the structural strength of the outer ring 1 and prevents deformation under stress, but also forms a fixed connection with the outer surface of the connecting post 21 in the connecting assembly 2 through several sets of symmetrically arranged first positioning holes 13 near the edge of the inner cavity. This accurately positions the relative position of the connecting post 21 and the outer ring 1, preventing the connecting post 21 from shifting or shaking during use. This connection method ensures a stable connection between the outer ring 1 and the connecting assembly 2, laying the foundation for the subsequent assembly of the inner ring 3 and the operation of the overall curtain ring. At the same time, the symmetrically distributed first positioning holes 13 ensure that the connecting post 21 is subjected to uniform stress.
[0021] As one implementation method in this embodiment, please refer to Figures 1-4As shown, the inner ring 3 includes a second ring outer wall 31. The second ring outer wall 31 is disposed on the outer surface of the connecting post 21 away from the first ring outer wall 11. A second support ring 32 is fixedly connected to the side of the second ring outer wall 31 away from the first ring outer wall 11. Several sets of symmetrically arranged second positioning holes 33 are fixedly connected to the center of the inner cavity of the second support ring 32 near the edge, and the second positioning holes 33 are fixedly connected to the outer surface of the connecting post 21.
[0022] The outer wall 31 of the second ring of the inner ring 3 serves as the core load-bearing component. It is located on the outer surface of the connecting post 21 away from the outer wall 11 of the first ring, providing basic position support for the connection between the inner ring 3 and the connecting assembly 2. The second support ring 32, which is fixedly connected to the outer wall 31 of the second ring away from the outer wall 11 of the first ring, can enhance the overall structural strength of the inner ring 3 and prevent the inner ring 3 from deforming when the curtain is pulled. On the other hand, through several sets of symmetrically arranged second positioning holes 33 at the center of its inner cavity near the edge, it forms a stable fixed connection with the outer surface of the connecting post 21, accurately defining the relative position between the inner ring 3 and the connecting post 21, and preventing the inner ring 3 from shifting or shaking during use.
[0023] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the outer surfaces of the first limiting ring 23 and the second limiting ring 25 are both provided with a smooth and wear-resistant coating. The smooth and wear-resistant coating is a polytetrafluoroethylene coating with a thickness of 0.1-0.3 mm.
[0024] During the operation of the curtain coil, it needs to come into contact with or move relative to components such as the outer ring 1, the inner ring 3, and the pivot ball 26. The polytetrafluoroethylene coating itself has excellent smoothness and wear resistance. On the one hand, it can significantly reduce the frictional resistance between the first limiting ring 23, the second limiting ring 25, and other contacting components, reduce wear caused by friction, and prevent jamming that affects the smoothness of curtain pulling after long-term use. On the other hand, the coating can protect the outer surface of the first limiting ring 23 and the second limiting ring 25, slow down their wear rate, and extend their service life.
[0025] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the outer wall 31 of the second ring has a rounded corner on the edge away from the second support ring 32, with a radius of 0.5-1mm. The inner wall of the inner ring 3 has several sets of anti-slip patterns evenly distributed in a spiral shape, with a depth of 0.15-0.25mm.
[0026] The 0.5-1mm radius rounded corner on the outer wall 31 of the second retaining ring away from the second support ring 32 prevents the sharp edges of the inner retaining ring 3 from scratching the operator's hands or snagging the curtain fabric during installation, disassembly, or curtain pulling. It also reduces friction wear between the edges and other components, improving safety and structural durability. Meanwhile, the evenly distributed spiral anti-slip texture with a depth of 0.15-0.25mm on the inner wall of the inner retaining ring 3 increases the friction between the inner cavity of the inner retaining ring 3 and the curtain rod, preventing unnecessary sliding and displacement of the curtain during hanging or pulling, ensuring that the curtain can stay stably in the required position, and avoiding misalignment of the curtain due to sliding.
[0027] Working principle: The outer ring 1 is securely connected to the connecting post 21 through the first positioning hole 13 of the first support ring 12 and the inner ring 3 through the second positioning hole 33 of the second support ring 32. With the limiting effect of the first limiting ring 23 and the second limiting ring 25, the components are effectively prevented from shifting or detaching, ensuring the overall structure is stable and reliable in long-term use. The pivot ball 26, which is slidably connected to the outer surface of the connecting post 21, can significantly reduce the frictional resistance between the outer ring 1 and the inner ring 3, making the curtain pull smoother. At the same time, the symmetrical connecting groove 27 of the pivot ball 26 ensures that its movement direction is accurate and avoids jamming. Moreover, the polytetrafluoroethylene wear-resistant coating on the outer surface of the first limiting ring 23 and the second limiting ring 25 can reduce component wear and extend service life. The rounded corner design of the edge of the outer wall 31 of the second ring can prevent scratches to hands or curtain fabric, improving safety. In addition, the spiral anti-slip texture on the inner cavity wall of the inner ring 3 can increase the friction with the curtain rod, preventing the curtain from sliding and shifting at will, and ensuring the stability of the curtain position.
[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
