Description
Technical Field
[0001] This utility model relates to the field of concealed frame door technology, and in particular to a concealed frame door structure using a non-deformable hanging panel process. Background Technology
[0002] A concealed frame door refers to a door with a hidden frame design. From the outside, the frame of the door is almost invisible, blending seamlessly with the surrounding walls and cabinets to create a simple, modern, and unified visual effect, making the space appear more open and transparent, especially suitable for interior design styles that favor minimalism. However, existing concealed frame doors have the following drawbacks: 1. The door structure requires adhesive bonding and edge sealing, a cumbersome process that makes it difficult to use different materials on both sides, such as a wooden front and a glass back; 2. Vibrations during opening and closing can easily cause the latex paint at the contact point between the frame and the wall to crack, affecting aesthetics; 3. Existing door structures primarily use silicone and adhesive for sealing and cushioning, which can lead to problems such as inadequate sealing, lack of rebound, and instability after long-term use; 4. Most existing doors use materials such as door liner filling, bridge dynamics boards, graphene cloud paperboard, aluminum honeycomb, paper honeycomb, and wooden ribs for internal filling, which only serves to stretch the side panels, resulting in very poor sound insulation.
