Abstract
An integrated hinge structure is disclosed herein, comprising a hinge shaft provided on a first connecting member and a hinge arm provided on a second connecting member, the hinge arm being rotatably connected to the hinge shaft, wherein a coupling structure is formed between the hinge shaft and the hinge arm, the coupling structure allowing the hinge arm only to be installed to or detached from the hinge shaft in a certain direction and allowing the installed hinge arm to rotate for any angle or freely while staying connected to the hinge shaft. Furthermore, the hinge shaft and the hinge arm are respectively formed integrally on the corresponding connecting members, providing a simple and firm structure.
Claims19
An integrated hinge structure, comprising:
- a hinge shaft provided on a first connecting member;
- and
- a hinge arm provided on a second connecting member, the hinge arm configured to be rotatably connected to the hinge shaft,
- wherein the hinge shaft has staggered surface features allowing the hinge arm with corresponding staggered surface features only to be installed to or detached from the hinge shaft in a certain direction and allowing the installed hinge arm to rotate at any angle while staying securely connected to the hinge shaft.
A hinge structure, comprising:
- a hinge shaft (1) provided on a first connecting member, the hinge shaft (1) having one or more cutting surfaces configured to be parallel to each other;
- and
- a hinge arm (2) provided on a second connecting member, the hinge arm (2) having one or more arc-sharped embracing arms configured to respectively receive the hinge shaft (1) through the one or more cutting surfaces at a predetermined direction;
- wherein the hinge shaft (1) is configured to:
- rotate freely and securely in the hinge arm (2);
- and
- only attach and detach from the hinge arm (2) at the predetermined direction.
A box comprising:
- a rear board;
- a cover board configured to rotate and cover the box;
- and a hinge connecting the rear board to the cover board, the hinge having:
- a hinge arm integrally formed with either the rear board or the cover board, the hinge arm having a plurality of arc-shaped embracing arms, and
- a hinge shaft integrally formed with either the rear board or the cover board, the hinge shaft having a cylindrical shape with one or more flat regions formed axially along the hinge shaft, each flat region axially aligning with a respective one of the arc-shaped embracing arms;
- wherein the one or more flat regions enable the hinge shaft to attach and detach from the hinge arms from a predetermined direction.
