In order to solve the above technical problems, in this embodiment, by setting an adjustable double-shaft hinge 3, the adjustable double-shaft hinge 3 has a primary 90 ° opening shaft 3-1 and a secondary 180 ° opening shaft 3-2, the primary 90 ° opening shaft 3-1 is used for connecting the hidden door steel structure 1, the secondary 180 ° opening shaft 3-2 is used for connecting the peripheral steel structure 4 located at the side of the hidden door steel structure 1, that is, through the adjustable double-shaft hinge 3, the hidden door can be opened completely, that is, 180 ° so as to ensure to meet the fire protection requirement, and reduce the fire protection hidden danger.

In order to ensure the overall coordination of the hidden door in the installation process and the stability of the door body in the opening and closing processes, the adjustable double-shaft hinges 3 are arranged in a plurality, and a plurality of the adjustable double-shaft hinges 3 are arranged at intervals along the height direction of the hidden door steel structure 1. Specifically, the adjustable biaxial hinge 3 in this embodiment has three, two of which may be disposed above the transverse midline of the hidden door, and the remaining one is installed below the transverse midline of the hidden door, thereby reducing the risk of dropping the hidden door.

In the actual construction process, the situation that the overall thicknesses of the peripheral steel structure 4, the peripheral veneer 5, the hidden door steel structure 1 and the hidden door veneer 2 are inconsistent generally exists, so that the traditional hinge is difficult to realize the connection effect. In order to solve the technical problems, the adjustable double-shaft hinge 3 in this embodiment has a detachable and adjustable structure adjusting plate one 3-3, an adjusting plate two 3-4 and an adjusting plate three 3-5, the adjusting plate one 3-3, the adjusting plate two 3-4 and the adjusting plate three 3-5 are surrounded to form a semi-surrounding structure, the adjusting plate one 3-3 and the adjusting plate two 3-4 are connected through a connecting piece one 3-6, the adjusting plate two 3-4 and the adjusting plate three 3-5 are connected through a connecting piece two 3-7, the first-stage 90 DEG opening rotating shaft 3-1 is formed at the tail end of the adjusting plate one 3-3, the second-stage 180 DEG opening rotating shaft 3-2 is formed at the tail end of the adjusting plate three 3-5, and compared with the conventional hinge which is a whole, the design can adapt to peripheral steel structures 4 and hidden door steel structures 1 with different distances and different thicknesses, so that the adaptability of the adjustable double-shaft 3 is enhanced, the applicable range is wider, and the hinge can be applied to the market and suitable for the hinge. Further, the first adjusting plate 3-3, the second adjusting plate 3-4, the third adjusting plate 3-5, the first connecting piece 3-6 and the second connecting piece 3-7 are provided with adjusting holes, the adjusting holes can be in a waist-shaped hole shape, or the adjusting holes on the first adjusting plate 3-3, the second adjusting plate 3-4 and the third adjusting plate 3-5 are in a waist-shaped hole shape, the adjusting holes on the first connecting piece 3-6 and the second connecting piece 3-7 are in a round hole shape, and locking pieces 3-8 are penetrated in the adjusting holes, so that the assembly of the adjustable double-shaft hinge can be realized, and the adjustment of multiple sizes of the adjustable double-shaft hinge can be realized.
