Document Type and Number:
Japanese Patent JP7338923
Kind Code:
B2
Abstract:
A hydraulic buffering hinge, comprising: a protrusion leaf (3), a recess leaf (18), a central shaft (7), a pressure spring (9), an independent oil cylinder (15), a limiting sleeve (2), a synchronizing sleeve (5) and a connecting sleeve (10), wherein a wall body of the limiting sleeve (2) is provided with two through grooves (201) in an axisymmetric manner. The through grooves (201) comprise non-parallel segments, wherein the non-parallel segments form an angle of less than 90 degrees with an end face of the limiting sleeve (2). The central shaft (7), which is located in the synchronizing sleeve (5), and the synchronizing sleeve (5) are provided, in a matching manner, with a synchronously rotating and axially slidable matching structure. The non-parallel segments of the through grooves (201) take, as a lift range, an upward axial movement direction of the central shaft (7) when the hinge is closed.
