Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, and more specifically, to a thermal break 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 on the door frame via pulleys. Existing door leaves typically have a one-piece profile structure, meaning the profile cross-section is identical and formed in one piece through extrusion. Since the profiles are primarily made of aluminum alloy, this one-piece door leaf structure generally has relatively poor heat insulation.

[0004] Therefore, a heavy-duty sliding door structure with thermal break is needed to solve the aforementioned technical problems. Utility Model Content
