Description

Technical Field

[0001] The utility model relates to the technical field of sliding doors, in particular to a threshold-free sliding airtight door. Background Art

[0002] Thresholds are usually used in conjunction with sliding doors. The staff fixes the threshold to the top of the ground, and then slides the sliding door along the inner wall of the threshold to achieve the purpose of opening and closing.
