Problems solved by technology

Since the fixed axis around which the door body rotates does not move, the door body is easy to exceed the side of the device when the door body is opened. For the case where the gap between the device and the wall is small, this kind of hinge structure is adopted. , will greatly limit the opening angle of the door, making it inconvenient to use
After continuous research and development, technicians have also invented embedded hinges, but the structure is complex, and it takes up a lot of space and is inconvenient to install.

Abstract

The invention discloses an embedded hinge device. The embedded hinge device comprises an installation part, a fixed part and a middle assembly, wherein a first arc-shaped groove is formed in one of the installation part and the middle assembly, a first connecting part which is connected with the first arc-shaped groove is arranged on the other one of the installation part and the middle assembly,and the middle assembly rotates relative to the installation part by using the arc center of the first arc-shaped groove as a first rotary axis; a second arc-shaped groove is formed in one of the fixed part and the middle assembly, a second connecting part which is connected with the second arc-shaped groove is arranged on the other one of the fixed part and the middle assembly, the fixed part rotates relative to the middle assembly by using the arc center of the second arc-shaped groove as a second rotary axis, and the first rotary axis is parallel to or coincides with the second rotary axis;and the fixed part is provided with a fixed part installing surface, the installation part is provided with an installation part installing surface, and both the fixed part installing surface and theinstallation part installing surface are perpendicular to the first rotary axis. The embedded hinge device has the advantages of convenience in installation and compact and reliable structure.

Description

technical field [0001] The invention relates to an embedded hinge device. Background technique [0002] The cabinets of many devices are equipped with openable doors. Usually, the door and the cabinet are rotatably arranged. In order to realize the rotation of the door relative to the door, a single-axis hinge is generally used. The fixed shaft of the hinge rotates to make a circular motion, thereby realizing the opening or closing of the door body. Since the fixed axis around which the door body rotates does not move, the door body is easy to exceed the side of the device when the door body is opened. For the case where the gap between the device and the wall is small, this kind of hinge structure is adopted. , will greatly limit the opening angle of the door body, making it inconvenient to use. After continuous research and development, technicians have also invented embedded hinges, but the structure is complicated, and it takes up a lot of space and is inconvenient to ...
