Abstract
Description
Technical Field
[0001] This application relates to the field of sliding doors, and more particularly to a sliding door with an anti-derailment structure. Background Technology
[0002] Sliding doors are a common type of door in homes, referring to doors that can be pushed and pulled. With technological advancements and diversified decoration methods, sliding doors have evolved from traditional panel surfaces to those made of glass, fabric, rattan, and aluminum alloy profiles. From sliding doors and folding doors to partition doors, the function and application range of sliding doors are constantly expanding. Sliding doors generally use a combination of rollers and guide rails to achieve their opening and closing function. The rollers are installed at the bottom of the door and roll along guide rails placed on the ground or under the door frame. This structural design allows the door to slide along a fixed track, saving space required for opening inwards or outwards, while also providing a smooth opening and closing experience.
[0003] Most sliding doors currently use a single row of rollers and guide rails. However, because the rollers continuously bear the weight of the door panel and the dynamic pressure during pushing and pulling, they may wear out or deform over time. In some cases, under violent or improper pushing and pulling, the rollers may completely come off the guide rails, causing the door or window to fall suddenly. This not only affects the user experience but also poses a threat to the user's safety. Utility Model Content
[0004] This application provides a sliding door with an anti-derailment structure. Through the cooperation of the second guide groove and the second guide wheel, the first slide can be assisted in sliding, preventing the first slide from derailing and increasing the stability of the first slide. By utilizing the cooperation of the third guide wheel and the third guide groove, the second slide can be limited to prevent it from derailing, thus avoiding affecting the user experience and increasing the safety of the user.
[0005] This application provides a sliding door with an anti-derailment structure, including a first guide rail and a second guide rail. The inner bottom wall of the first guide rail has a first guide groove. A first slide block is engaged inside the first guide rail. A first groove is formed on the bottom surface of the first slide block. The inner side wall of the first groove is fixedly inlaid with first bearings arranged at equal intervals. A first rotating column is fixedly connected inside each group of first bearings. A first guide wheel is installed on the side of each group of first rotating columns that are close to each other. A second slide block is engaged inside the second guide rail. A door frame is fixedly connected to the upper surface of the first slide block and the bottom surface of the second slide block. A protective door is installed inside the door frame. A symmetrical third guide groove is formed on the inner side wall of the second guide rail.
[0006] Furthermore, a second guide groove is provided on the inner side wall of the first guide rail, and fixed blocks arranged at equal intervals are fixedly connected to the outer surface of the first slide.
