Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a concealed mini hinge for a decorative door panel. Background Art

[0002] With the increasing application of decorative wall panels and invisible doors, some users hope to achieve the fusion of door panels and decorative panels. Traditional door panels either have hinges exposed, or require a lot of installation space at the back, and then reserve holes to fix hidden door panels laterally to achieve the fusion of decorative wall panels and hidden doors.

[0003] However, in some special areas, such as public corridors, the width of the corridor design cannot meet the fire protection requirements due to the influence of the floor area ratio, and the installation space of the decorative panels and door panels has to be compressed. In addition, some customers do not want to waste too much installation space due to decorative panels. For example, the fire corridor is only 1250m away, and the fire corridor needs to ensure that it is not less than 1.2m. In this case, 5cm tiles need to be laid on each side, and only about 3cm of the finished surface will be left on the other side. The finished decorative aluminum panel and the opening door panel cannot be larger than 3cm. Therefore, we propose hidden mini hinges for decorative door panels. Utility Model Content
