Description

Technical Field

[0001] The utility model relates to the technical field of curtains, and more specifically to a horizontal curtain controlled by dual systems. Background Art

[0002] At present, most of the existing ordinary curtains are controlled by a single system. The control system can use a motor or a control head to drive the square steel to drive the rope tube and wind the rope, while the curtains controlled by the dual system use two systems to control the two lower beams to achieve different adjustments of the curtains. For example, the day and night curtains can refer to the patent CN214997340U previously applied for by the inventor, but after a period of use, its system defects have become more and more obvious: first, the rope threading is complicated. The current dual-system curtains require the rope to be threaded in the track to achieve the function of controlling the upper and lower curtains on both sides, and the production and processing are more troublesome. Secondly, once the rope is wound inside the aluminum material, it is difficult to keep the friction force on each rope consistent. This can easily lead to the problem of difficulty in maintaining the height of the left and right sides of the curtain. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a horizontal curtain controlled by a dual system, which has a simple and reliable structure, is easy to produce and process, and the heights of the left and right sides of the curtain can be kept consistent during use.

[0005] The utility model is further configured as follows: the double-row rope reels are provided with two groups, which are respectively located at two sides of the curtain body.

[0006] The utility model is further configured as follows: transition pieces are provided in both the outlet hole A and the outlet hole B, the end of the transition piece facing the inside of the double-row rope reel is provided with a trumpet-shaped transition surface, and the end of the transition piece facing the outside of the double-row rope reel is provided with an arc chamfer.

[0007] The utility model is further configured as follows: the double-row rope reel also includes a base, the base is provided with two clamping cavities, one high and one low, and the two rope reel tubes are respectively located on the two clamping cavities.

[0008] The utility model is further configured as follows: a driving mechanism is provided at one end of the curtain body, a transmission rod extending from the driving mechanism and extending into the curtain body, and the transmission rod is connected to the rope winding tube and rotates synchronously.

[0009] The utility model is further configured as follows: comprising a folding curtain A and a folding curtain B, wherein the upper and lower ends of the folding curtain A are respectively connected to the curtain body and the top surface of the lower beam A; the upper and lower ends of the folding curtain B are respectively connected to the bottom surface of the lower beam A and the top surface of the lower beam B.

[0010] In summary, the utility model has the following beneficial effects:

DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] This embodiment discloses a horizontal curtain controlled by dual systems, such as Figure 1-6 As shown, it includes a curtain body 1 and liftable lower beams A21 and B22. When in use, the curtain body 1 is fixed to the upper edge of the window, and the lower beams A21 and B22 are used for lifting and lowering and drive the corresponding curtain to lift and lower. In this embodiment, a double-row rope reel 3 is arranged in the curtain body 1. The double-row rope reel 3 includes two rope reel tubes 301 arranged side by side. The two rope reel tubes 301 are respectively wound with ropes A4 and B5. At the same time, the rope outlet directions of ropes A4 and ropes B5 wound on the rope reel tubes 301 are opposite, that is, the two rope reel tubes 301 are turned back and forth in the axial direction; the two sides of the bottom of the double-row rope reel 3 are provided with wire outlet holes A6 and wire outlet holes B7 for ropes A4 and ropes B5 to pass through, and ropes A4 and ropes B5 are respectively connected to the lower beam A21 and the lower beam B22. Please refer to Figure 2 When in use, the rope A4 is retracted and released to control the lower beam A21 to rise and fall, and the rope B5 is retracted and released to control the lower beam B22 to rise and fall. Figure 3-5 After the two rope winding tubes 301 arranged in reverse front and back are wound around the rope A4 and the rope B5, the ends of the rope A4 and the rope B5 are naturally located on both sides of the double-row rope winding device, which simplifies the routing of the ropes. The reverse front and back arrangement of the rope winding tubes 301 also makes each rope completely independent, and there will be no problem of the ropes crossing and entangled with each other.

[0021] Furthermore, two sets of double-row rope reels 3 are provided, which are respectively located on both sides of the curtain body 1. In this embodiment, since ropes A4 and ropes B5 are directly extended from the corresponding wire outlet holes A6 and B7 without being routed inside, the friction between the ropes and the inside of the curtain body 1 is very small and basically consistent, and the two sets of double-row rope reels 3 located on both sides of the curtain body 1 can keep the length of the ropes consistent when they are retracted and released, and there will be no problem of different heights on both sides of the curtain.

[0022] Further, see Figure 6 A transition piece 9 is provided in both the outlet hole A6 and the outlet hole B7. The end of the transition piece 9 facing the inside of the double-row rope reel 3 is provided with a transition surface 901 in the shape of a flared mouth, and the end of the transition piece 9 facing the outside of the double-row rope reel 3 is provided with an arc chamfer. The transition surface 901 is provided to allow the rope to have a transition when passing through the outlet hole, thereby reducing the wear of the rope and ensuring the smoothness of the rope retraction and release; the arc chamfer has a similar function, mainly playing a transition protection role when the rope is reeled into the double-row rope reel 3.

[0023] Further, see Figure 3The double-row rope reel 3 also includes a base 302, on which two clamping cavities 3021, one high and one low, are provided, and the two rope reel tubes 301 are respectively located on the two clamping cavities 3021. By providing two clamping cavities 3021, one high and one low, the two rope reel tubes 301 are slightly staggered in height, so that the two rope reel tubes 301 are not directly opposite to each other in the diameter parts with the largest width, but the diameter parts with the largest width are staggered in the high and low directions, which can save the lateral volume of the double-row rope reel 3 to a certain extent. At the same time, after the rope reel tubes are staggered in height, due to the different rotation centers, the stress of the two rope reel tubes on the base will be dispersed, thereby improving the durability of the base to a certain extent.

[0024] Further, see Figure 1-2 One end of the curtain body 1 is provided with a driving mechanism 8, on which a transmission rod 801 extending into the curtain body 1 is extended, and the transmission rod 801 is connected to the rope tube 301 and rotates synchronously. The driving mechanism 8 can be driven by a motor or a bead wheel or a bead rope.

[0025] Furthermore, the present embodiment includes a folding curtain A10 and a folding curtain B11. The upper and lower ends of the folding curtain A10 are respectively connected to the curtain body 1 and the top surface of the lower beam A21; the upper and lower ends of the folding curtain B11 are respectively connected to the bottom surface of the lower beam A21 and the top surface of the lower beam B22. When in use, the lifting and lowering of the lower beam A21 and the lower beam B22 will drive the corresponding folding and unfolding of the folding curtain A10 and the folding curtain B11. The folding curtain A10 and the folding curtain B11 should have different shading effects, so that the ratio of the two curtains can be flexibly adjusted according to needs during the day and at night to ensure comfortable indoor light. At the same time, the folding curtain A10 and the folding curtain B11 can preferably be a honeycomb curtain.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
