Description

Technical Field

[0001] The utility model relates to the field of hinges, in particular to a hinge which is easy to position. Background Art

[0002] In the rotating connection of the safety door or the rotating railing, a hinge is generally installed between the safety door or the rotating railing, and the hinge is a device that allows the safety door or the rotating railing to rotate relative to each other. The hinge is generally composed of two aluminum alloy parts, which are connected together by an axis. The aluminum alloy parts rotate with the axis of the axis as the center of the circle, thereby allowing the safety door or the rotating railing to move relative to each other.
