Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a door frame profile and a swing door using the same. Background Technology

[0002] A hidden door is a design that blends seamlessly with the wall in terms of visual appearance, creating a more complete and unified wall surface. It is suitable for various design styles. When a hidden door is closed, the shape, size, and style of the exit are not easily discernible.

[0003] In the present technology, hidden doors typically include a door frame fixed to the door opening in the wall and a door body hinged to the door frame. The door body is usually composed of a core panel and decorative panels set on both sides of the core panel. Hidden doors are usually thin and their sound insulation performance usually cannot meet the needs of home use.

[0004] As shown in the existing patent document with announcement number CN220226617U, a hidden door is disclosed, including a door frame assembly for use with a door opening in a wall and a door core assembly that matches the door frame assembly. The door core assembly includes an inner door panel, an outer door panel, and a sound insulation filler disposed between the inner door panel and the outer door panel. The door core assembly also includes a door core profile disposed outside the sound insulation filler and located between the inner door panel and the outer door panel.

[0005] As shown in the aforementioned existing technical documents, although it can enhance sound insulation, it also has the following drawbacks:

[0006] Door frame profiles have poor applicability; a single door frame profile can only be used for one type of installation. For example, as shown in the aforementioned patent document, the third door frame profile 13 can only be used for outward-opening doors and cannot be used for inward-opening doors or outward-opening doors. The inability of door frame profiles to be universally applicable not only leads to high manufacturing costs and large inventory pressure for manufacturers, but also has many other drawbacks. Utility Model Content
