Description

Technical Field

[0001] This utility model relates to the field of daily consumer goods technology, specifically a novel roller shutter guide rail buckle structure. Background Technology

[0002] A window screen is a mesh structure installed on windows to prevent insects and other small animals from entering the room. It typically consists of a mesh fabric and a fixed frame, allowing air and sunlight to pass through while effectively blocking insects from entering. In addition, it provides a degree of privacy, preventing outsiders from observing the interior. Window screens are usually made of durable mesh materials such as fiberglass, polyester fiber, or stainless steel wire, with a reasonable structural design, secure installation, and long-term use. Choosing a window screen that suits your window size and personal needs can effectively improve the living environment and ensure indoor air quality and comfort.

[0003] Currently available window screens are available in both detachable and non-detachable versions. Non-detachable screens, after prolonged use, often require forceful removal when damaged, resulting in high costs and low efficiency. Detachable screens, on the other hand, allow users to quickly remove and replace the screen, improving the user experience. However, current detachable screens typically use clips for connection, which facilitates disassembly and cleaning. However, the clips in existing detachable screens are generally made of rigid materials, making storage inconvenient after disassembly, thus impacting the user experience.

[0004] In addition, the most significant drawback of the aforementioned roller shutter guide rail buckles is that the sliding stop in the guide rail is a flexible fixing component, which is easily damaged during the sliding process. Summary of the Invention

[0005] The purpose of this utility model is to provide a novel roller shutter guide rail buckle structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A novel roller shutter guide rail buckle structure includes a guide rail unit and a buckle unit; The guide rail unit includes a guide rail body, which includes a left side plate located on the left side, an upper plate and a lower plate extending to the right from the upper part of the left side plate, a right side plate connected below the lower plate, and a right connecting plate connected between the upper plate and the lower plate. The lower end of the left side plate extends to the right and bends upward at the end to form an upward bending portion. The left side plate has an upper hook plate extending to the right below the lower plate. The upper hook plate bends downward at the end to form a downward bending portion. The downward bending portion and the upward bending portion are opposite to form a guide groove for the sliding of the snap-fit ​​unit. The buckle unit includes a hot melt fabric and a sliding piece disposed on the top of the hot melt fabric. The sliding piece has multiple rows and columns of holes. The hot melt fabric covers both sides of the sliding piece and is fixedly connected to the sliding piece by hot melt adhesive. The sliding piece of the buckle unit is adapted to the guide groove and is slidably disposed in the guide groove and slides along the length direction of the guide groove.
