Detailed Description
The technical scheme of the invention is further described and illustrated by specific embodiments below, so that the technical scheme is clearer and more obvious. Other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.
As shown in fig. 2 to 12, the embodiment discloses a hidden hinge, which includes three parts, namely a rotating shaft 1, a door leaf 3 and a door frame 4, and is different from a conventional hinge in that the hinge is bilaterally symmetrical and has a single sheet structure, in which the rotating shaft 1 is disposed between a door frame 7 and a door leaf 5, and the door frame 4 of the embodiment includes, as viewed from the side, a first sealing ring 41, a first arc-shaped portion 42 and a first straight portion 43 which are connected in sequence, one end of the first arc-shaped portion connected with the first sealing ring extends to the left side, and the other end bends to the right side and is connected with the first straight portion 43;
the door leaf 3 comprises a second sealing ring 31, a second arc-shaped part 32 and a second straight strip part 33 which are connected in sequence, one end of the second arc-shaped part 32 connected with the second sealing ring 31 extends to the left side, and the other end is connected with the second straight strip part 33;
the first sealing ring 41 and the second sealing ring 31 are sleeved on the rotating shaft 1 and can rotate relative to the rotating shaft 1. The hinge of this embodiment is installed in door leaf, door frame and is close to indoor one side, has avoided the hinge to expose outdoor.
In a preferred embodiment, the arc of the first arcuate portion 42 is greater than or equal to 90 °; alternatively, the arc of the second arc-shaped portion 32 is less than or equal to 90 °.
The number of the first sealing rings 41 is two, the two first sealing rings are symmetrically arranged at two ends of one long side of the door frame piece 4, and the second sealing ring 31 is arranged between the two first sealing rings 41.
The first straight portion 43 of the present embodiment is provided with a mounting hole for mounting and fixing to a door frame; alternatively, the second straight portion 33 is provided with a mounting hole for mounting and fixing to the door leaf. The door leaf piece 3 and the door frame piece 4 are respectively arranged on the door leaf 5 and the door frame 7 through two straight parts by a detachable mode that screws penetrate through the mounting holes and the like, and the fixed installation of the whole hinge is realized.
Preferably, the door leaf 4 or the door leaf 3 is integrally formed.
The first arc-shaped part 42 of the present embodiment has an arc radius larger than the radius of the first closing ring 41; alternatively, the radius of the arc of the second arc part 32 is larger than the radius of the second closing ring 31.
In order to reduce the wear caused by the rotation of the hinge, the hidden hinge of the present embodiment further includes a gasket 2, which is sleeved on the rotating shaft 1 and located between the first closing ring 41 and the second closing ring 31.
In the present embodiment, as shown in fig. 2, the door is provided with the hidden hinge on the front side (outdoor side), and the first straight portion 43 and the second straight portion 33 are respectively fixed to the side surface of the door frame 7 and the side surface of the door 5, that is, located on the indoor side. The hidden hinge can also be applied to other furniture such as windows, cabinet doors and the like to play the same role. The whole hinge is arranged on the inner side of the door, and the anti-theft safety is higher.
Preferably, the door frame and the door side surface may be provided with mounting grooves for fixing the second linear portion and the first linear portion.
In order to avoid the local exposure of the hinge on one indoor side, the door leaf 5 is also provided with a bound edge 6. The edge 6 is mounted on the door leaf 5 by screw or rivet connection. The edge cover 6 is a structure with a groove on the side surface, and the first closing ring 41 and the second closing ring 31 are arranged in the groove, as shown in fig. 13 and 14. The edge 6 contains all the circular rotating parts (the first closing ring 41, the second closing ring 31 and the rotating shaft 1) of the door 3 and the door 4, and the hinge can not be seen on the front surface, the back surface and the side surface of the door after the door is closed.
