Description

TECHNICAL FIELD

[0001] The utility model relates to a sliding door technical field, concretely relates to a sliding door split pulley support structure. BACKGROUND

[0002] In modern architectural design, sliding doors are widely used in various places due to their space-saving and flexible opening characteristics, especially super heavy sliding doors, which can bear greater weight and meet the use requirements of large-area and heavy door bodies. However, with the increasing demand for building energy efficiency, how to ensure the functionality of sliding doors while achieving good thermal insulation performance has become a problem to be solved.

[0003] The traditional super heavy sliding door pulley structure is mostly designed in a double-row pulley integrated manner. For example, the 25 panoramic door pulley. Although this design ensures the stability and load-bearing capacity of the door body to some extent, the integrated installation method poses a serious challenge to the thermal insulation performance. Specifically, when the integrated pulley is installed on the opening fan, it inevitably connects the inner profile and the outer profile together, thereby forming a direct connection between the inner and outer structures at the pulley installation position. This connection not only destroys the original thermal barrier, causing heat to easily pass through the pulley installation area, seriously affecting the overall thermal insulation effect of the sliding door, but also does not meet the high standard requirements of modern green buildings for energy efficiency.

[0004] In addition, the installation process of the traditional integrated pulley often requires damaging the existing material main structure to process a large enough pulley installation position. This approach not only increases the processing difficulty and cost, but more importantly, it compromises the integrity of the overall fan material structure, weakening the structural strength and stability of the door body. Especially for super heavy sliding doors, any damage to the main structure can adversely affect the load-bearing capacity and service life of the door body.

[0005] In view of the above problems, there is an urgent need in the market for a new pulley support structure that can meet the functional requirements of super heavy sliding doors and effectively ensure thermal insulation performance. This structure should avoid direct connection between the inner and outer profiles to ensure the integrity of the thermal barrier; at the same time, its installation method should minimize damage to the existing material main structure to maintain the strength and stability of the overall fan material structure.
