[0027] Reference Figures 1 to 3 The curtain hanging structure of the embodiment of the utility model comprises a guide rail 200 and a curtain ring 100, wherein the curtain ring 100 comprises a ring body 110, a slider 120 and a ball 140, wherein the ring body 110 is used for being clamped with a hook of the curtain; a connecting column 130 is fixedly connected between the slider 120 and the ring body 110, two ball mounting grooves 121 are arranged on one side of the slider 120 close to the ring body 110, and a spring 122 is built in the ball mounting groove 121; the ball 140 is built in the ball mounting groove 121, and the ball 140 can and can rotate around the center in the ball mounting groove 121, one end of the spring 122 is fixedly connected to the end face of the ball mounting groove 121, and the other end abuts against the surface of the ball 140, and a slide groove 210 is provided through the guide rail 200 along the extension direction of the guide rail 200, the slider 120 is slidably connected to the slide groove 210, and the ball 140 abuts against the inner bottom surface of the slide groove 210.

[0028] In actual use, the sliders 120 of the plurality of curtain rings 100 are slidably matched with the guide rails 200, the ring bodies 110 of the plurality of curtain rings 100 are engaged with the hooks of the curtain cloth, and bear the entire curtain cloth, and the ball 140 is subjected to the elastic force from the spring 122 in the ball mounting groove 121, so that the ball 140 fits into the slide groove 210 of the guide rail 200 and abuts against the inner bottom surface of the slide groove 210, wherein, during the sliding process of the curtain ring 100, the ball 140 rolls in the ball mounting groove 121, specifically, under the constraints of the ball mounting groove 121 and the spring 122, the ball 140 rolls around the center of the ball 140 and forms rolling friction with the slide groove 210 to realize opening or retracting the curtain cloth.

[0029] In summary, refer to Figure 2 By utilizing the direct contact between the rolling ball 140 and the bottom surface of the guide rail 200, the sliding friction in the old design is replaced by rolling friction, which effectively reduces the friction force, reduces the wear of the curtain ring 100 on the guide rail 200, and can also reduce the abnormal noise generated by the curtain ring 100 during the sliding process, thereby improving the user experience.

[0030] Preferably, in order to further improve the silencing effect, the surface of the rolling ball 140 is covered with a rubber layer (not shown in the figure). The rubber layer is elastic and has a low friction coefficient. Combined with the sliding mode of rolling friction, it can effectively reduce noise.

[0031] In some embodiments, reference Figure 3In order to constrain the position of the ball 140, a stop block 123 is provided at one end of the ball mounting groove 121 close to the ring body 110, and the stop block 123 is provided with a notch 1231. The notch 1231 is circular, and the diameter of the notch 1231 is smaller than the diameter of the ball 140, wherein the ball 140 partially protrudes from the notch 1231, and the inner wall of the notch 1231 is completely fitted with the wall surface of the ball 140, so that when the ring body 110 slides along the guide rail 200, the ball 140 rolls and always keeps in contact with the inner bottom surface of the slide groove 210, while preventing the ball 140 from shaking.

[0032] Preferably, the curtain ring 100 is made of metal, and its material may be stainless steel or aluminum.

[0033] It is worth mentioning that, refer to Figure 2 The connecting column 130 includes a fixed sleeve 131 and an adjusting rod 132, wherein the fixed sleeve 131 is fixedly connected to the side of the ring body 110; the adjusting rod 132 is linearly movable and built into the sleeve, wherein the adjusting rod 132 moves in the fixed sleeve 131 along the axial direction to adjust the length of the connecting column 130, so as to facilitate the adjustment of the height of the entire curtain fabric. Specifically, a first thread (not shown in the figure) is provided on the inner side of the sleeve, and a second thread (not shown in the figure) is provided on the outer side of the adjusting rod 132, and the first thread and the second thread are meshed. In the above scheme, through the meshing of the first thread and the second thread, when the adjusting rod 132 is rotated, the adjusting rod 132 can be driven to move axially in the fixed sleeve 131 to adjust the length of the entire connecting column 130.

[0034] Preferably, refer to Figure 2 and Figure 3 Along the extension direction of the slide groove 210, the inner bottom surface of the slide groove 210 is provided with a downwardly concave slide rail 220, and the ball 140 is built into the slide rail 220 and can roll along the slide rail 220. The concave slide rail 220 can constrain the position of the ball 140, ensuring that the ball 140 can and can only roll along the axial direction of the guide rail 200. In addition, in order to constrain the sliding track of the entire slider 120 and avoid deviation, further, both sides and the top end surface of the slider 120 are provided with wear-resistant blocks 230, and the other side of the wear-resistant block 230 is in contact with the inner side surface of the guide rail 200. The wear-resistant block 230 is used to fill the space between the slider 120 and the inner side of the guide rail 200, so as to prevent the slider 120 from shaking. At the same time, the wear-resistant block 230 is selected from soft rubber with a small friction coefficient, which can effectively reduce wear and reduce noise.

[0035] Specifically, in order to improve the strength of the entire guide rail 200, in some embodiments, the processing technology of the guide rail 200 is to first produce the hardware, and then perform injection molding on the periphery of the hardware, so that the entire guide rail 200 constitutes a structure in which the hardware is embedded in the injection molded part. Its structure can improve the structural strength relative to the all-plastic part. At the same time, relative to the guide rail 200 with all-hardware parts, the guide rail 200 with an injection molded part shell can beautify the surface, making the entire guide rail 200 more beautiful. Among them, as a conventional installation direction in this field, the guide rail 200 is generally installed on the wall by rivets. Of course, other methods such as bonding, clamping, etc. should also be the technical solutions included in this application.

[0036] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
