Description

Technical Field

[0001] The utility model relates to the technical field of double-sliding door lower slide block structures, in particular to an adaptive swing pulley assembly. Background Art

[0002] The double sliding door structure is a common door structure for shower rooms. Two parallel guide rail structures are set on the bottom and top surfaces of the door. A roller structure for support is fixed at the bottom of the sliding door. Retaining edges are set on both sides of the guide rail to limit the lateral swing of the sliding door. However, in order for the glass door to slide smoothly, the thickness of the glass needs to be slightly smaller than the width of the guide rail groove. Therefore, there will be a large gap between the glass door and the guide rail groove.
