Description

A drill-free, cordless roller blind structure Technical Field

[0001] This utility model relates to the technical field, and in particular to a drill-free, cordless roller blind structure. Background Technology

[0002] Currently, the main structure of roller blinds involves winding the curtain fabric onto a pivot, with a controller on the pivot. A beaded cord is then wound around the controller. Pulling the beaded cord causes the pivot to rotate clockwise or counterclockwise via the controller, thus controlling the raising or lowering of the curtain fabric. In actual use, it has been found that corded roller blinds suffer from frequent damage, and there is also a safety hazard in households with children, as the beaded cord can become entangled around their necks and cause suffocation. Although cordless roller blinds have emerged to address these issues, such as the cordless roller blind structure disclosed in Chinese Utility Model Patent No. CN209742749U, these require fixing to the wall with screws using a fixed bracket, which requires wall damage and is inconvenient to install. Furthermore, the internal structure of the pivot controller, tension adjuster, and curtain positioner is relatively complex, increasing manufacturing costs. Summary of the Invention

However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0032] Example 1: Referring to Figures 1, 2, 3, and 4, a no-drill, cordless roller blind structure includes a no-drill adjuster 1 and an adjustment head box 2 corresponding to the no-drill adjuster 1. The no-drill adjuster 1 is provided with a pivot assembly 3, and the adjustment head box 2 is provided with a sleeve assembly 4. The pivot assembly 3 is provided with a support rod 5, and the sleeve assembly 4 is provided with a connecting pipe 6. The support rod 5 and the connecting pipe 6 are connected by a one-way damper 7. The support rod 5 is provided with a cordless assembly 8, and a main pipe 9 is provided between the no-drill adjuster 1 and the adjustment head box 2. This arrangement not only achieves cordless installation but also enables no-drill installation. It can adapt to window frames of different widths, does not require wall damage, and is convenient and quick to install. At the same time, the structure is also relatively reasonable, facilitating production and installation.

[0033] Example 2: Based on Example 1, as shown in Figures 1, 4, and 5, the no-drill adjuster 1 includes an end cap 11 and an adjusting disc 12 disposed on the end cap 11. The adjusting disc 12 is provided with a pivot assembly 3. This arrangement is reasonable and easy to implement. The end cap 11 is inserted into the adjusting disc 12 for easy installation.

[0034] As shown in Figures 3, 4, and 5, the pivot assembly 3 includes a fixed tube 31 mounted on the adjusting plate 12. A return spring (not shown in the figure) is installed inside the fixed tube 31. A device sleeve 32 is fitted over the fixed tube 31. A connecting tube 33 is installed at the other end of the fixed tube 31. A one-way damper 7 is installed on the connecting tube 33. The one-way damper 7 is connected to a support rod 5. This arrangement is reasonable, facilitates installation, and is also conducive to normal operation in the later stages.

[0035] Example 3: Based on Example 1 or Example 2, as shown in Figures 1, 2, 4, and 6, the adjusting head box 2 includes a box body 21 and a mounting post 22 disposed on the box body 21. An adjusting member 23 is disposed on the box body 21 to adjust the sleeve assembly 4 to move back and forth along the support rod 5. The clockwise and counterclockwise rotation of the adjusting member 23 drives the adjusting sleeve assembly 4 to move. The adjusting member 23 is a helical adjusting rod, which facilitates the back-and-forth movement of the adjusting sleeve assembly 4.

[0036] As shown in Figures 4, 6, 7, 8, and 9, the sleeve assembly 4 includes an outer sleeve 41 fitted onto the mounting post 22. One end of the outer sleeve 41 has an integrally formed gear ring 42, which meshes with the adjusting component 23 for transmission. The other end of the outer sleeve 41 is provided with a first connector 43 for connecting to the non-pull-cord assembly 8. An installation sleeve 44 is fitted onto the outer sleeve 41, which is used to connect one end of the main pipe 9. The first connector 43 is connected to the non-pull-cord assembly 8. In this embodiment, the first connector 43 and the non-pull-cord assembly 8 are connected by threads. This arrangement is reasonable and easy to implement. One end of the support rod 5 is connected to the first connector 43. In this embodiment, the outer sleeve 41 and the first connector 43 are connected together by rivets 45. As further illustrated in Figures 3, 4, and 9, the cordless assembly 8 includes a second connector 81 mounted on the support rod 5. The second connector 81 is connected to the first connector 43 via a cordless spring 82, which is fitted onto the support rod 5. This design facilitates cordless operation and makes it more convenient for users. The cordless spring 82 shown in Figures 3, 4, and 9 is a traditional spring, well-known in the art.

[0037] The sleeve assembly 4 includes an outer sleeve 41 that is fitted onto the mounting post 22. One end of the outer sleeve 41 is integrally formed with a gear ring 42, which meshes with the adjusting component 23 for transmission. The outer sleeve 41 is connected to the first connector 43 by a rivet 45, and a mounting sleeve 44 is fitted onto the outer sleeve 41. During assembly, the sleeve assembly 4 is installed into the adjusting head box 2. Then, one end of the support rod 5 is installed into the first connector 43 of the sleeve assembly 4. The end of the spring 82 without a pull rope on the support rod 5 is screwed tightly to the first connector 43. A second connector 81 is installed on the other end of the support rod 5. The second connector 81 is screwed tightly to the other end of the spring 82 without a pull rope. Then, the non-drilling adjuster 1 (end cap 11 is inserted into the adjusting plate 12) is connected to the pivot assembly 3. A one-way damper 7 is installed on the pivot assembly 3. A connecting pipe 6 is installed on the one-way damper 7. Then, the main pipe 9 is installed from the spring 8 without a pull rope and connected to the mounting sleeve 44. Then, the connecting pipe 6 is connected to the other end of the support rod 5 through the second connector 81. At this time, the device sleeve 32 is connected to the other end of the main pipe 9. The main pipe 9 is made of aluminum. This utility model of a cordless roller blind uses a one-way damper 7 and an adjusting component 23 on the housing 21 to adjust the movement of the sleeve assembly 4 along the support rod 5. It can achieve the function of not pulling a cord, gently pulling the roller blind down by hand (no rebound), and slowly returning the roller blind to the default state by hand. The hole-free adjusting device 1 does not require a track and can be installed and disassembled easily.

[0038] All standard parts used in this application can be purchased from the market, and the specific connection methods of each part adopt conventional means such as springs that are mature in the existing technology, and will not be described in detail here.

[0039] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
