Hinge

The utility model relates to the technical field of hinges, and discloses a hinge which comprises a hinge body, a first mounting seat and a second mounting seat are arranged on the left side and the right side of the hinge body respectively, an inner mounting plate is detachably mounted on the inner side of the first mounting seat through bolts, and a hydraulic copper cylinder is fixedly mounted on the inner side of the inner mounting plate. And a connecting piece is movably mounted on the right side of the hydraulic copper cylinder. When the hinge is used, the second mounting seat pulls the hydraulic copper cylinder, meanwhile, the two groups of dampers drive the two groups of piston rods to move rightwards, when springs on the outer walls of the piston rods are extruded to a certain degree, the two groups of dampers are pulled to buffer the opened hinge, and otherwise, when the hinge is closed, the two groups of dampers are pulled to buffer the opened hinge. The two sets of limiting blocks can buffer the cl
