Description

Technical Field

[0001] The utility model belongs to the technical field of hinges, and particularly relates to a double-opening 180-degree adjustable invisible hinge. Background Art

[0002] A hinge is a connecting piece widely used in switching devices such as doors and windows, and its main function is to enable the doors and windows to rotate and open around a certain axis. With the continuous progress of building and home design, the requirements for hinges are also constantly increasing. Especially in modern decoration, invisible hinges have gradually become a popular choice due to their concealment and aesthetics.

[0003] The invisible hinge has high aesthetics because it can be completely hidden between the door frame and the door panel without exposing the external hinge structure. However, the invisible hinge also faces some technical challenges in practical applications, mainly reflected in the complexity of adjustment and installation.

[0004] The installation of traditional invisible hinges requires precise adjustment during the installation process to ensure that the gap between the door panel and the door frame is uniform and the door opens and closes smoothly. This process usually requires the use of special tools and techniques, and has relatively high requirements for the technical level and experience of installers.

[0005] During the actual use process, the installation position of the door panel may need to be adjusted due to the deformation of the door frame or installation errors. Traditional invisible hinges usually lack a flexible adjustment mechanism, resulting in greater difficulty in adjusting the hinges in this case, and often requiring the disassembly of some components to make adjustments.

[0006] In view of this, overcoming the above-mentioned defects of the prior art is an urgent problem to be solved in this technical field. Summary of the Utility Model
