Abstract
Description
TECHNICAL FIELD
[0001] The utility model discloses a novel hinge structure belongs to the technical field of home building materials. BACKGROUND
[0002] The damping hinge is an important pivot hardware, and is widely applied to furniture, doors and windows and the like. The damping hinge mainly has two forms, one is a hydraulic hinge, and the other is a torsion spring. The hydraulic damping hinge is suitable for connecting the cabinet door of furniture such as a wardrobe, a book cabinet, a floor cabinet, a TV cabinet, a cabinet, a wine cabinet and a storage cabinet. The existing damping hinge has a complex structure, a high manufacturing cost, is prone to movement interference in the use process, has impact when the door is opened and closed, has a short service life and is prone to damage. Therefore, it is urgent to provide a novel hinge structure which has a simple structure, a low manufacturing cost, smooth movement, a long service life and the like. SUMMARY
[0003] The utility model discloses a novel hinge structure which has a simple structure, a low manufacturing cost, smooth movement and a long service life.
[0004] The utility model discloses a novel hinge structure which has a simple structure, a low manufacturing cost, smooth movement and a long service life.
[0005] The fixed part comprises a first fixed frame in the shape of a door, and the first fixed frame is composed of a first left side plate, a first top plate and a first right side plate. The left side of the first left side plate and the right side of the first right side plate are respectively provided with a fixed edge, and the fixed edge is provided with a fixed hole.
[0006] The movable part comprises a second fixed frame in the shape of a door and a front fixed plate. The second fixed frame is composed of a second left side plate, a second top plate and a second right side plate. The front fixed plate is provided with a fixed hole.
[0007] The first crankshaft;
[0008] The second crankshaft;
[0009] The second fixed frame is located in the interior of the first fixed frame, and is rotatably installed in the interior of the first fixed frame through the first crankshaft and the second crankshaft. The first crankshaft is located in front of the second crankshaft, and the first fixed frame is provided with a gap for the second fixed frame to flip and be clamped.
[0010] The utility model discloses a novel hinge structure which has a simple structure, a low manufacturing cost, smooth movement and a long service life. BRIEF DESCRIPTION OF DRAWINGS
