Adjustable hidden hinge

Abstract

The invention provides an adjustable hidden hinge which solves the problem that exposure of the hinge can result in easy destruction of the hinge. The key points of the technical scheme of the adjustable hidden hinge is that the adjustable hidden hinge comprises an upper hinge plate, a lower hinge plate and a door frame hinge plate, wherein the upper hinge plate and lower hinge plate are located in a door frame; both the upper hinge plate and the lower hinge plate are connected with an adjusting plate which is connected with a fixed plate and located between a door frame hinge and the fixed plate; a door shaft in rotating connection with a door leaf is disposed on the upper hinge plate and the lower hinge plate; the door shaft is inserted in the door leaf; the adjusting plate is provided with an adjusting component for adjusting the relative position of the door leaf and the door frame. The adjustable hidden hinge has the advantages of realizing the hiding of the hinge with the upper hinge plate and the lower hinge plate connected with the door frame and located in the door frame, being simple in structure, ensuring a compact structure of the door frame and the door leaf, keeping the function of the hinge, eliminating the impact of hinge exposure on the overall appearance of a door, avoiding the inconvenience caused by the hinge exposed on the outside of the door frame and thedoor leaf, saving space, and improving service life of the hinge.

Description

technical field [0001] The invention relates to the technical field of hinges, in particular to an adjustable hidden hinge. Background technique [0002] The realization of the opening and closing function of the door leaf requires the use of hinges. The hinges currently used have a very simple structure, that is, the front page and the auxiliary page are installed on the door leaf and the door frame respectively, and they are connected in series with a rotating shaft. What also have is comparatively complicated, adopts two supports, and wherein a support is provided with slide bar, has groove on the other support, and slide bar slides in the groove, reaches the purpose of closing up. [0003] The hinges of these mechanisms are installed on the door frame or door leaf, which are exposed to the outside, at least, their rotating shafts are exposed to the outside. After installation, the appearance of the entire door will be compromised. When it comes to burglars, it is easy ...

AI Technical Summary

Problems solved by technology

Some are more complicated, using two brackets, one of which is equipped with a sliding rod, and the other bracket has a groove, and the sliding rod slides in the groove to achieve the purpose of closing.

[0003] The hinges of these mechanisms are installed on the door frame or door leaf, which are exposed to the outside, at least, their rotating shafts are exposed to the outside. After installation, the appearance of the entire door will be compromised. When it comes to thieves, it is easy to damage the hinge and carry out burglary
