Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, and more specifically, to a heavy-duty sliding door structure. Background Technology

[0002] Sliding doors are a common type of door in homes, which can be pushed and pulled. The base materials for sliding doors are generally aluminum alloy and PVC. Due to its lightweight and high strength, aluminum alloy is a high-end material for sliding doors and has gradually replaced PVC products. Because sliding doors are more convenient and quick to open and close, they are more suitable for spaces such as kitchens and bathrooms that require frequent opening and closing. This necessitates a heavier sliding door to improve its stability.

[0003] Traditional sliding doors generally consist of a door frame and a door leaf. The door frame is fixed to the wall, while the door leaf is mounted on a guide rail within the door frame via pulleys. Existing door frames typically use identical profiles, meaning the cross-sections of the profiles on the left, right, top, and bottom of the frame are all the same. While this makes assembly convenient, it makes it difficult to adapt to different wall surfaces during actual construction. Measurement errors can lead to problems with the door frame's installation.

[0004] Therefore, a heavy-duty sliding door structure needs to be designed to solve the aforementioned technical problems. Utility Model Content
