Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-8, the hidden hinge of the present invention comprises a hinge slot 4, a rotating shaft sleeve 6 rotatably connected with the hinge slot 4 via a rotating shaft 5, the rotating shaft sleeve is integrally connected with a movable plate 7 having a first mounting hole 12, the hinge slot 4 is integrally connected with a hinge base 3 having a second mounting hole 11,

wherein, the two sides of the hinge slot are respectively provided with a rotating shaft hole 9 which is symmetrically arranged, the rotating shaft 5 is arranged in the rotating shaft hole, and the rotating shaft sleeve 6 is arranged in the hinge slot 4 by arranging the rotating shaft 5 in the rotating shaft hole 9 after being sleeved on the rotating shaft 5.

Specifically, the rotating shaft 5 and the hinge slot 4 are welded together after being connected through the rotating shaft hole 9. The rotating shaft sleeve is arranged on the rotating shaft and can rotate freely within the range of 0-90 degrees.

When the rotating shaft sleeve rotates to 90 degrees, the rotating shaft sleeve can be contacted with the hinge seat, so that the rotation of the rotating shaft sleeve is limited. The rotating shaft sleeve is fixed on the movable plate, the rotating shaft sleeve rotates along with the movable plate, the movable plate is installed on the door or the window through the screw, when external force is applied to the door or the window, the door or the window drives the movable plate to rotate around the rotating shaft, and therefore relative rotating motion of the door or the window around the door frame or the window frame is achieved.

When the hinge seat is used, the hinge seat is fixed with the sinking surface of the door frame or the window frame 1 through the screw 2, the hinge groove 4 is embedded into a matching embedded groove formed on the mounting surface of the door frame or the window frame, the outer plane of the hinge seat and the surface of the door frame or the window frame are on the same plane and completely hidden inside the connected piece, and then the movable plate is fixed on the door or the window body through the screw, so that the installation is realized as shown in fig. 6. Thus, the hidden hinge can make the door or window rotate around the hinge shaft to reach the aim of rotating one movable object around one fixed object.

Specifically, the rotating shaft sleeve is of a C-shaped structure, and is connected with the movable plate 7 through an L-shaped portion connected with one end, as shown in fig. 8, a small opening is formed between the free end of the rotating shaft sleeve and the L-shaped connecting portion, and the diameter of the opening is smaller than that of the rotating shaft, so that the rotating shaft cannot slide out.

Preferably, the movable plate is a rectangular plate, a rectangular hole is formed in the middle of the rectangular base plate of the hinge base and is matched with the rectangular opening of the rectangular hinge groove in a matching manner, so that the opening direction of the hinge groove is exposed and then is connected with the rotating shaft sleeve through the rotating shaft.

It should be noted that the hinge slot 4 and the hinge base 3 with the second mounting hole 11 may be integrally formed, or welded or riveted together after forming the respective components, and the rotating shaft sleeve and the movable plate 7 with the first mounting hole 12 may be integrally formed, or welded or riveted together after forming the respective components.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
