Description

Technical Field

[0001] This utility model relates to the field of screen curtain technology, specifically a pull-cord telescopic screen curtain. Background Technology

[0002] As people's demands for home decoration and functionality continue to increase, screen curtains, as a type of curtain that can both block light and provide partitions while also being aesthetically pleasing, have been widely used in various places such as homes and offices. However, most screen curtains on the market currently have fixed lengths, which to some extent limits their applicability and fails to meet the diverse needs of different customers for window sill sizes.

[0003] Commercially available screen curtains typically come in standard lengths, while window sill sizes vary considerably across different architectural and interior design styles. Fixed-size screen curtains struggle to fully accommodate all window sills, especially non-standard sizes, creating significant usability challenges. Customers often need to cut their existing screen curtains to fit different window sill sizes, which not only increases complexity but can also negatively impact the curtain's aesthetics and functionality.

[0004] Since existing screen curtains do not offer customized sizes, many consumers need to cut them themselves or have them professionally tailored to fit their specific windowsills. While this solves the size mismatch problem, it introduces several potential issues. The cutting process may result in fabric waste, and for non-professionals, the accuracy and quality of the cutting are difficult to guarantee, potentially leading to a distorted finished product or inconvenience in use. Furthermore, cutting may require re-drilling holes and adjusting track positions, further increasing installation complexity and time costs.

[0005] To accommodate various window sill sizes, some screen curtain products on the market have adopted large-size track designs, attempting to meet demand by offering more length options. However, with the increase in track size, the product's volume and weight also increase, leading to a sharp rise in transportation costs. Larger packaging sizes not only increase logistics costs but also make product storage and handling more difficult, ultimately impacting the efficiency of the entire supply chain. No solutions have yet been proposed to address these technical issues. Utility Model Content

[0006] To address the problems in related technologies, this utility model proposes a pull-cord telescopic screen curtain to overcome the aforementioned technical issues in existing technologies. The purpose of this utility model is to double the track length of the screen curtain through a telescopic design, making it adaptable to windowsills of different sizes. This greatly improves the flexibility and versatility of the product, eliminating concerns about mismatches between the windowill size and the screen curtain length. The track length can be adjusted according to actual needs to meet the shading requirements of different spaces, thus enhancing the convenience and adaptability of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pull-cord type telescopic screen curtain, including an inner rail, with outer rails movably connected to both sides of the inner rail, an end cap provided at one end of the outer rail, a pull cord provided between the inner rail and the outer rail, the pull cord being connected to the inner rail and the outer rail respectively, a slider provided at the bottom of both the inner rail and the outer rail, a slide bar provided at the bottom of the slider, a fabric provided on one side of the slide bar, a hook surface and a napped surface provided between the slide bar and the fabric, the hook surface being connected to the slide bar, the fabric being connected to the napped surface, and the hook surface and the napped surface being bonded together.

[0008] Preferably, the outer rail is provided with a through hole one and a through hole two, one end of the pull rope is connected to the inner rail, and the other end of the pull rope passes through the through hole one and the through hole two in sequence, and the end is connected to the inner rail.

[0009] Preferably, the hook surface and the slide bar are connected by riveting.

[0010] Preferably, the fabric and the napped surface are connected by sewing.

[0011] Preferably, the inner rail, outer rail, and slide bar are all connected by metal materials.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model is a pull rope telescopic screen curtain. By setting outer rails at both ends of the inner rail, the function of extending the rail under any size can be realized, which greatly improves the applicability of the screen curtain. Users can adjust the length of the rail according to actual needs, flexibly adapt to windowsills of different sizes, and meet more diverse decoration needs. At the same time, the separate design of the inner rail and the outer rail not only provides convenience for the installation of the product, but also allows for flexible disassembly and adjustment as needed, improving the adaptability and user experience of the product. (2) This utility model is a pull-cord telescopic screen curtain. By setting the inner rail and outer rail with pull-cord limiting design, the user can easily control the separation and limiting of the inner and outer rails by disassembling and tightening the pull cord, which simplifies the installation and disassembly process of the screen curtain, makes the disassembly of the rail more convenient, does not require complicated tools, reduces maintenance costs and improves the user's ease of operation. (3) This utility model is a pull cord telescopic screen curtain. By setting the hook surface to connect with the slide strip, the fabric to the pile surface, and the hook surface and the pile surface to be bonded together, the problem of unstable fabric sliding in traditional curtains is avoided.

[0015] 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. Example

[0016] Please see Figure 1-3 This utility model proposes a technical solution for a pull-cord type telescopic screen curtain: A pull-cord type telescopic screen curtain includes an inner rail 1, with outer rails 2 movably connected to both sides of the inner rail 1. One end of the outer rail 2 is provided with an end cap 3, specifically, the end cap 3 is used to prevent parts from slipping off the outer rail 2; a pull cord 4 is provided between the inner rail 1 and the outer rail 2, and the pull cord 4 is connected to both the inner rail 1 and the outer rail 2 respectively. Specifically, when the size is pulled to its maximum, the pull cord 4 is tightened to a limit, preventing it from detaching from the inner rail 1. When the inner rail 1 is needed... When separating from the outer rail 2, untie the knot on the pull rope 4 to separate the inner rail 1 from the outer rail 2; both the inner rail 1 and the outer rail 2 are equipped with sliders 7 at the bottom, sliders 7 are equipped with slide bars 8 at the bottom, and one side of the slide bar 8 is equipped with fabric 9. A hook surface 10 and a napped surface 11 are provided between the slide bar 8 and the fabric 9. The hook surface 10 is connected to the slide bar 8, the fabric 9 is connected to the napped surface, and the hook surface 10 and the napped surface 11 are bonded together. Specifically, when it is necessary to clean or replace the fabric 9, simply tear off the fabric 9.
