Hinge having adjustable buffer

Abstract

Disclosed in the present application is a hinge having an adjustable buffer, the hinge comprising a hinge cup, a hinge body, a hinge arm, a buffer, a hinge shaft, a mounting base, a buffer cylinder, a pushing member, a first limiting member, and a second limiting member. When the second limiting member is toggled to working position I, a limiting hook portion blocks in the front of an extruding hook block, shortening the distance by which a pushing portion pushes the first limiting member to move, and when the hinge is folded, the stroke of the buffer cylinder compressed by the first limiting member is reduced, reducing the buffering force of the hinge. When the second limiting member is toggled to working position II, the limiting hook portion moves to the rear of a clearance position, and when the hinge is folded, the distance by which the pushing portion pushes the first limiting member to move returns to the original state, such that the stroke of the buffer cylinder compressed by the first limiting member is increased, increasing the buffering force of the hinge.
