Description

Technical Field

[0001] The utility model relates to the technical field of low threshold sealing structures, in particular to a low threshold door with a middle seal. Background Art

[0002] Profile swing door structure has been widely used on balconies. Since the swing door of the balcony is in contact with the outside world, its water tightness requirements are relatively high. If the threshold of the swing door is high, it can prevent rainwater from entering the room, but there will be certain obstacles for entering and exiting the swing door, especially for carrying movable objects or people with limited mobility. It is very unfriendly; if a low threshold structure is used, the water tightness and air tightness will be reduced. Utility Model Content
