Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a from buffering five metals hinge, its includes articulated arm 1 and hinge cup 2, and is articulated through first connecting rod 3 and second connecting rod 4 between articulated arm 1 and the hinge cup 2, and first connecting rod 3 is provided with reset torsion spring 5 with the articulated department of articulated arm 1, and reset torsion spring 5 drives hinge cup 2 toward 1 direction beat of articulated arm all the time, its characterized in that: the damping device is characterized in that a fixed sleeve 6 is fixedly arranged in the hinged arm 1, a mounting hole 61 is formed in the end face of the fixed sleeve 6, a buffering cylinder 7 is arranged in the mounting hole 61, a sliding sleeve 8 is further sleeved outside the fixed sleeve 6 in a sliding mode, a pressing plate 81 is arranged at the rear end of the sliding sleeve 8 and is buckled and pressed on the buffering cylinder 7, and when the sliding sleeve 8 moves relative to the fixed sleeve 6, the buffering cylinder 7 is driven to move through the pressing plate 81 to generate damping; the two sides of the sliding sleeve 8 are provided with connecting plates 82, the connecting plates 82 protrude out of the two sides of the sliding sleeve 8, the two sides of the second connecting rod 4 extend upwards to be provided with driving arms 41, the driving arms 41 are in contact with the connecting plates 82, and when the hinge is closed, the second connecting rod 4 pushes the sliding sleeve 8 to move relative to the buffer cylinder 7 through the driving arms 41 and the connecting plates 82, so that door closing damping is generated.
