[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0046] The rope winder provided by this utility model can improve the assembly efficiency of the internal components of the rope winder while ensuring stable winding of the control rope of the curtain slab, thus meeting the requirements of mass production.

[0047] In embodiments of this utility model, such as Figures 1 to 5As shown, the cord winder includes a first base 1, a second base 2, a winding assembly 3, and a guide assembly 4. The first base 1 has a first connecting portion 11 and a first positioning portion 12. The second base 2 has a second connecting portion 21 and a second positioning portion 22. The first positioning portion 12 and the second positioning portion 22 are positioned and engaged. The first connecting portion 11 and the second connecting portion 21 are detachably connected. The inner wall surfaces of the first base 1 and the second base 2 together form a cord winding channel 101. The winding assembly 3 is rotatably disposed in the cord winding channel 101 and is used to wind the curtain control cord. The guide assembly 4 is slidably disposed in the cord winding channel 101 and is used to guide the winding position of the curtain control cord.

[0048] In this embodiment, during the assembly process of the rope winder, the winding assembly 3 and the guide assembly 4 are first positioned on the inner wall of the first base 1 or the second base 2. Then, the first positioning part 12 and the second positioning part 22 are used to provide assembly positioning points for the first base 1 and the second base 2. Finally, the first base 1 and the second base 2 are joined together through the first connecting part 11 and the second connecting part 21 to complete the assembly of the rope winder. The entire assembly process is streamlined, and the positioning cooperation between the first positioning part 12 and the second positioning part 22 effectively ensures the assembly accuracy when the first base 1 and the second base 2 are joined. This ensures stable winding of the control rope of the curtain while improving the assembly efficiency of the internal components of the rope winder, meeting the requirements of mass production.

[0049] In one embodiment, such as Figure 2 and Figure 3 As shown, the first base 1 has a first groove 13, and the second base 2 has a second groove 23. The first groove 13 and the second groove 23 are coaxial and form a rope winding channel 101. Multiple first connecting portions 11 are formed, and the multiple first connecting portions 11 surround the first groove 13, with equal spacing between any two adjacent first connecting portions 11. Multiple second connecting portions 21 are formed, and the multiple second connecting portions 21 surround the second groove 23, with equal spacing between any two adjacent second connecting portions 21.

[0050] By adopting the above arrangement, multiple first connecting parts 11 and multiple second connecting parts 21 can be used in corresponding cooperation to complete the splicing of the first base 1 and the second base 2, ensuring the installation stability of the rope winder. At the same time, when the rope winder winds or releases the curtain control rope, the multiple first connecting parts 11 and multiple second connecting parts 21 can cooperate to balance the lateral forces on the first base 1 and the second base 2, reducing the risk of misalignment of the first base 1 and the second base 2 due to the lateral forces when the roller assembly 3 rotates, and improving the stability of the roller assembly 3 in winding or releasing the curtain control rope in the rope winding channel 101.

[0051] The first connecting part 11 and the second connecting part 21 can be connected by a snap-fit ​​method. The housing edge of the first base 1 has multiple slots or buckles, and the housing edge of the second base has corresponding multiple buckles or slots. When connecting the first base 1 and the second base 2, the buckles can be snapped into the corresponding slots. The connection stability of the first base 1 and the second base 2 is ensured by the cooperation of multiple slots and buckles.

[0052] Alternatively, the first connecting part 11 and the second connecting part 21 can also be connected by a threaded connection. The bottom and / or top of the first base 1 and the bottom and / or top of the second base 2 are formed with multiple threaded holes. Bolts or studs are screwed into the coaxial threaded holes to ensure the connection stability of the first base 1 and the second base 2 by utilizing the threaded engagement between the bolts or studs and the threaded holes.

[0053] In this embodiment, the preferred connection method between the first base 1 and the second base 2 is as follows: multiple slots and buckles are formed on the outer edges of the first base 1 and the second base 2 respectively, and the first base 1 and the second base 2 are connected by fastening. At the same time, threaded holes are formed on the top of the first base 1 and the top of the second base 2, and the threads are used to assist in fastening, thereby preventing the first base 1 and the second base 2 from being misaligned due to force expansion.

[0054] As a further improvement to the above embodiments, such as Figures 2 to 4 As shown, the first chamber 13 has a first inner wall 131, and the second chamber 23 has a second inner wall 231. A first gap is formed between the first inner wall 131 and the first positioning part 12, and a second gap is formed between the second inner wall 231 and the second positioning part 22. The first gap and the second gap are equal. Furthermore, by using the first positioning part 12 and the second positioning part 22 as positioning points to splice the first base 1 and the second base 2, the inner wall surface of the rope winder can form a rope winding channel 101 without splicing steps, ensuring the rotational stability of the winding assembly 3 in the rope winding channel 101 and avoiding the problem of jumping or shaking of the winding assembly 3.

[0055] Among them, such as Figure 3 and Figure 4 As shown, the inner wall 131 of the first groove and the inner wall 231 of the second groove may include the vertical inner wall 106 and the horizontal inner wall 107 of the rope winding channel 101, wherein the vertical inner wall 106 is an inner wall surface perpendicular to the length direction of the rope winding channel 101, and the horizontal inner wall 107 is an inner wall surface parallel to the length direction of the rope winding channel 101.

[0056] It should also be noted that, such as Figures 2 to 4As shown, the first positioning part 12 and the second positioning part 22 can be positioned by the cooperation of positioning protrusions and positioning holes. For example, a positioning protrusion is formed on the side of the first base 1 and a positioning hole is formed on the side of the second base 2. When splicing the first base 1 and the second base 2, the positioning protrusion can be inserted into the positioning hole to provide a positioning point for splicing the first base 1 and the second base 2, ensuring the splicing accuracy of the first base 1 and the second base 2, ensuring that the first base 1 and the second base 2 cannot produce relative displacement after being connected, and preventing the connection between the two from becoming loose.

[0057] In this embodiment, the slat control rope includes, but is not limited to, the pull rope for raising and lowering the Venetian blind slats, and the ladder rope for adjusting the shading angle of the Venetian blind slats. The roller blind can wind the pull rope and the ladder rope respectively, so as to drive the roller blind to operate by using a drive motor or other drive structure, thereby realizing the winding and releasing of the pull rope, or using the ladder rope to adjust the tilt angle of the slats, and correspondingly adjust the shading angle of the slats.

[0058] In order to facilitate the winding or releasing of the pull rope, such as Figure 2 and Figure 5 As shown, the winding assembly 3 includes a winding shaft 31 and a first guide wheel 32. The first base 1 and the second base 2 have at least two seat holes 102. Two adjacent seat holes 102 extend along the length direction of the winding channel 101. The winding shaft 31 is rotatably connected to the seat holes 102 so that the winding shaft 31 can rotate relative to the first base 1 and the second base 2 after being connected to a drive motor or other drive components.

[0059] The first guide wheel 32 is rotatably disposed between the first base 1 and the second base 2. The first base 1 and the second base 2 have rope inlet holes 103. The first guide wheel 32 is located between the rope inlet hole 103 and the rope winding shaft 31. The end of the rope winding shaft 31 away from the rope inlet hole 103 has a rope fixing end 311. The guide assembly 4 is located between the rope fixing end 311 and the first guide wheel 32.

[0060] With the above arrangement, when the roller assembly 3 is placed inside the rope winder, the rope roller 31 can be connected to the seat hole 102 of the first base 1 or the second base 2, and the fixed end of the pull rope can be fixed to the fixed end of the rope roller 31. Then, the end of the pull rope that connects to the curtain slat passes through the guide assembly 4 and the first guide wheel 32 in sequence, and then passes out through the rope inlet hole 103, so as to connect the pull rope to the curtain slat.

[0061] Therefore, the rope winder of this embodiment can complete the fixed arrangement of the pull rope in the rope winding channel 101 before the first base 1 and the second base 2 are spliced. It can provide sufficient operating space for the arrangement of the pull rope, ensure the stability of the connection between the fixed end of the pull rope and the rope winding shaft 31, and eliminate the need to repeatedly check whether the pull rope is loose during assembly, thus effectively improving the assembly efficiency of the pull rope inside the rope winder.

[0062] In one embodiment, to facilitate the connection of the fixed end of the pull rope to the fixed end of the rope winding shaft 31, such as... Figure 5 and Figure 6 As shown, end caps 312 are connected to both ends of the winding shaft 31, and the winding shaft 31 is rotatably connected to the seat hole 102 through the end caps 312. The end cap 312 away from the rope inlet hole 103 has a through hole 313, and the fixed end of the rope can be inserted into the through hole 313 from one side of the winding shaft 31 and fixed to the end face of the end cap 312 away from the winding shaft 31, so as to facilitate the fixing of the fixed end of the rope, and at the same time facilitate the rotation of the winding shaft 31 to wind or release the winding shaft 31.

[0063] In this embodiment, the winding process of the pull rope on the winding shaft 31 is as follows: the fixed end of the pull rope is fixed to the fixed end of the winding shaft 31, and after the overall assembly of the rope winder is completed, the winding shaft 31 is connected to the drive shaft of the drive motor, the drive motor runs, and the winding shaft 31 rotates. At the same time, the guide component 4 is used to guide the winding position of the curtain control rope, thus completing the winding process of the pull rope on the winding shaft 31.

[0064] To ensure the pull rope is evenly wound on the winding shaft 31, such as Figures 5 to 7 As shown, the guide assembly 4 includes a rotary slider 41, a translation slider 42, and a second guide wheel 43. The rotary slider 41 is slidably disposed on the rope winding shaft 31, and the rope winding channel 101 has a threaded guide surface 104, with the outer wall surface of the rotary slider 41 engaging with the threaded guide surface 104. The translation slider 42 is slidably disposed on the rope winding channel 101 and slides along the length direction of the rope winding channel 101. A limiting groove 421 is formed on the top of the translation slider 42, and the limiting groove 421 engages with the rotary slider 41. The second guide wheel 43 is rotatably disposed on the translation slider 42. A rope winding groove 422 is formed on the side of the translation slider 42 facing the fixed rope end 311, and the rope winding groove 422 faces the rope winding shaft 31 and is located above the second guide wheel 43.

[0065] With the above arrangement, after the pull rope is fixed to the fixed end of the rope winding shaft 31, it can pass through the rope winding slot 422 into the interior of the translation slider 42, and after passing around the second guide wheel 43, extend towards the first guide wheel 32. By utilizing the threaded guide surface 104 in cooperation with the rotating slider 41, when the rope winding shaft 31 rotates, the rotational motion of the rope winding shaft 31 can be converted into the translational motion of the rotating slider 41 within the rope winding channel 101. This allows the rotating slider 41 to drive the translation slider 42 to slide along the length direction of the rope winding channel 101, thereby changing the position of the pull rope relative to the rope winding shaft 31 and ensuring that the pull rope can be evenly wound and stably exited on the rope winding shaft 31.

[0066] In this embodiment, the second guide wheel 43 is preferably a wheel with a sufficiently large diameter to provide the pull rope with a sufficiently large winding angle and bending radius, effectively reducing the fatigue risk during the pull rope winding process and improving the service life of the pull rope. The diameter D of the wheel can be adjusted according to the diameter d of the pull rope. For example, the ratio of the wheel diameter D to the pull rope diameter d can be set to be greater than or equal to 20 to provide a sufficiently large winding angle and bending radius for the pull rope.

[0067] It should also be noted that the outer wall surface of the rotating slider 41 is a threaded surface, so that the threaded surface of the rotating slider 41 can engage with the threaded guide surface 104 inside the rope winding channel 101. With the cooperation of the rotating slider 41 and the translation slider 42, the rotational motion of the rope winding shaft 31 is converted into the translational motion of the translation slider 42. During the rotational engagement between the rotating slider 41 and the threaded guide surface 104, the rotating slider 41 applies a lateral force to the first base 1 and the second base 2. At this time, through the cooperation of multiple first connecting parts 11 and multiple second connecting parts 21, the misalignment between the first base 1 and the second base 2 can be avoided.

[0068] It should also be noted that the first base 1 and the second base 2 are injection molded from high-strength plastics (such as nylon, PA or polyoxymethylene) to ensure that the concentricity and dimensional accuracy of the threaded guide surface 104 with the first groove 13 and the second groove 23 meet the process requirements. At the same time, by utilizing its high wear resistance or low coefficient of friction, it ensures that no abnormal noise is generated when the rope winding shaft 31 and the first base 1 and the second base 2 generate mutual dry friction, thereby reducing wear and further simplifying the process, making the assembly process of the rope winding device simpler and faster, and improving assembly efficiency.

[0069] Among them, such as Figure 7 As shown, a translation boss 423 is formed on the outer wall surface of the translation slider 42, and a translation groove 105 is formed on the inner wall surface of the rope winding channel 101. The translation boss 423 and the translation groove 105 are slidably connected so that the translation slider 42 can move along the length direction of the rope winding channel 101 by utilizing the cooperation between the translation boss 423 and the translation groove 105, thereby changing the position of the winding point of the rope relative to the rope winding shaft 31.

[0070] In this embodiment, as Figure 3 , Figure 4 , Figure 10 and Figure 11As shown, a first lateral spacing L1 is formed between the first positioning part 12 and the threaded guide surface 104, and a second lateral spacing L2 is formed between the second positioning part 22 and the threaded guide surface 104. The first lateral spacing L1 and the second lateral spacing L2 are equal to ensure that after the first base 1 and the second base 2 are spliced, the concentricity between the threaded guide surface 104 of the first base 1 and the threaded guide surface 104 of the second base 2 can meet the process requirements. In this way, when the threads are processed on the inner wall surface of the first base 1 and the inner wall surface of the second base 2, the alignment of the two sets of thread lines can be effectively ensured, thereby improving the assembly accuracy of the splicing of the first base 1 and the second base 2.

[0071] It should be noted that, for example Figure 10 and Figure 11 As shown, the first lateral spacing L1 is the distance between the end of the threaded guide surface 104 and the first positioning part 12 extending along the length direction of the rope winding channel 101, and the second lateral spacing L2 is the distance between the end of the threaded guide surface 104 and the second positioning part 22 extending along the length direction of the rope winding channel 101.

[0072] It should also be noted that after the first base 1 and the second base 2 are formed, the first base 1 and the second base 2 can be spliced ​​separately, and the inner wall surfaces of the first base 1 and the second base 2 can be threaded simultaneously to ensure the continuity of the threaded surfaces.

[0073] In this embodiment, to facilitate the winding or unwinding of the ladder rope, such as Figure 2 and Figure 8 As shown, the roller assembly 3 includes a flapping wheel 33. A first base 1 and a second base 2 form an arc-shaped support 331. The flapping wheel 33 is rotatably mounted on the arc-shaped support 331, and is coaxial with the winding shaft 31. The rope inlet hole 103 is located below the flapping wheel 33. When fixing the fixed end of the ladder rope, the fixed end of the ladder rope can be passed through the rope inlet hole 103 to the arc-shaped support 331 and fixed to the flapping wheel 33. After the ladder rope is wound, the flapping wheel 33 is installed on the arc-shaped support 331. The drive shaft connected to the winding shaft 31 drives the flapping wheel 33 to rotate, thereby winding the ladder rope and adjusting the tilt angle of the curtain slats to control the shading angle of the curtain slats.

[0074] Among them, the arc support 331 is preferably a semi-circular mounting position.

[0075] Furthermore, to avoid tilting the page-turning wheel 33 during installation, such as... Figure 2 and Figure 8As shown, the arc-shaped support 331 is located outside the rope winding channel 101. A first guide post 14 is formed on the first base 1, and a second guide post 24 is formed on the second base 2. The first guide post 14 and the second guide post 24 face the arc-shaped support 331 and extend in the same direction, i.e., they are arranged parallel to each other. The first guide post 14 and the second guide post 24 are used to guide the page-turning wheel 33 to the position of the arc-shaped support 331 during installation, ensuring the accuracy of the page-turning wheel 33's installation direction and further reducing the installation difficulty of the page-turning wheel 33. Preferably, the first guide post 14 is arranged vertically on the first base 14, and the second guide post 24 is arranged vertically on the second base 2, so as to guide the page-turning wheel 33 from above the arc-shaped support 331 and install it onto the arc-shaped support 331.

[0076] The distance between the first guide post 14 and the second guide post 24 is greater than or equal to the diameter of the rotating shaft of the page-turning wheel 33. This ensures that when the page-turning wheel 33 is installed on the arc support 331 under the guidance of the guide posts, a certain clearance is formed between the rotating shaft of the page-turning wheel 33 and the first guide post 14 and the second guide post 24. This prevents the first guide post 14 and the second guide post 24 from interfering with the page-turning wheel 33 during installation, thus avoiding jamming during the installation of the page-turning wheel 33. This further improves the ease of installing the page-turning wheel 33 from above the arc support 331.

[0077] In this embodiment, to ensure the stability of the paddle wheel 33 in the rope winder, such as Figure 8 and Figure 9 As shown, the scroll assembly 3 also includes a pressure cap 34. The pressure cap 34 is disposed above the arc support 331, and the page-turning wheel 33 is located between the pressure cap 34 and the arc support 331, so that the page-turning wheel 33 is confined to the first base 1 and the second base 2 by the cooperation of the pressure cap 34 and the arc support 331, thereby ensuring the installation stability of the page-turning wheel 33.

[0078] Specifically, a guide groove 341 is formed on the side of the pressure cap 34 facing the arc support 331, and the first guide post 14 and the second guide post 24 are slidably connected to the guide groove 341; a buckle hole 342 is formed on the side of the pressure cap 34 away from the arc support 331, and the first base 1 and the second base 2 are formed with protruding buckles 343, and the buckle hole 342 is engaged with the protruding buckle 343. When installing the pressure cap 34, the pressure cap 34 can be slid from above the first guide post 14 and the second guide post 24 to the arc support 331, and the buckle hole 342 and the protrusion buckle 343 are engaged to complete the installation of the pressure cap 34 on the first base 1 and the second base 2. The cooperation of the protrusion buckle 343 and the buckle hole 342 is used to prevent the pressure cap 34 from becoming loose from the outer shell. The cooperation of the guide groove 341 with the first guide post 14 and the second guide post 24 is used to prevent the pressure cap 34 from shifting, ensuring the connection stability of the pressure cap 34 with the first base 1 and the second base 2, and further ensuring the limiting effect of the pressure cap 34 on the page turning wheel 33.

[0079] It should also be noted that, in order to ensure the limiting effect of the cap 34 on the page-turning wheel 33, such as Figure 9 As shown, the pressure cap 34 has an arc-shaped pressure hole 344 on the side facing the first base 1 and the second base 2. When the pressure cap 34 is snapped onto the first base 1 and the second base 2 through the snap hole 342 and the protruding buckle 343, the arc-shaped pressure hole 344 is coaxial with the arc-shaped support 331. The arc-shaped pressure hole 344 and the arc-shaped support 331 work together to limit the movement of the page turning wheel 33 and ensure the rotational stability of the page turning wheel 33.
