Description

Technical Field

[0001] The utility model relates to the field of hardware accessories, in particular to a hinge. Background Art

[0002] Hinge, also known as hinge or hinge, is a copper decoration of furniture, often composed of two folding types, which is a metal part that connects two parts of furniture and enables them to move. It usually consists of a pair of metal or non-metal leaves connected by an axle pin, often in a two-fold type. This device enables two parts of doors, covers or other parts that need to swing open and close to be connected and rotated relative to each other.

[0003] The existing hinges are equipped with multi-axis connections on each hinge piece, and the pins on each hinge piece flip along each axis to realize the flipping of the entire hinge. However, this design has precision problems in installation and production. The precision length and width between each axis are different, which will increase the time required for processing the axis during the processing process and increase the cost. At the same time, as the use time increases, the axis and the axis will wear each other, resulting in reduced precision and difficulty in flipping. The more axes are set, the more difficult it is to replace the parts due to wear, which increases the difficulty of maintenance and maintenance. Utility Model Content
