[0002] Chinese Patent Document No. CN2780937Y disclosed on May 17, 2006 a hidden hinge for furniture doors that can be adjusted in three dimensions. It includes a movable base that can be fixed on the door body, an adjustable base that can be fixed on the door frame and a connecting The rotating arm in between, wherein the adjustable base includes a bottom plate that can be fixed on the door frame, a middle plate that slides up and down on the bottom plate, and an upper adjustment plate that slides back and forth on the middle plate. Laminate structure, in which the plate is formed by alloy casting and then secondly extruded and riveted with the lower adjustment plate. Although the production process is simple, this process has hidden dangers to the quality of the hinge. After the alloy casting is extruded twice The internal structure of the material changes, such as looseness, cracking, etc., so it is difficult to ensure the reliability of the riveting between the alloy casting and the upper adjustment plate, resulting in a low strength of the hinge, and the door panel is easy to fall, and the service life is short , and the structure is complex, there are many assembly parts, and the manufacturing and maintenance costs are high
