Hydraulic speed regulation structure with hidden hinge

Abstract

The utility model provides a hydraulic speed regulation structure with a hidden hinge, which comprises a shell component and a hydraulic buffer component vertically mounted in the shell component, a speed regulation gear is mounted at the bottom of a speed regulation oil needle of the hydraulic buffer component, and a speed regulation knob is mounted on the shell component along the transverse direction in a sliding manner. One end, close to the speed regulating gear, of the speed regulating knob is provided with a bevel gear part meshed with the speed regulating gear, and the bevel gear part is separated from the speed regulating gear in a normal state; during adjustment, the speed adjusting knob slides to enable the bevel gear part to be meshed with the speed adjusting gear, and then the speed adjusting knob is rotated to drive the speed adjusting oil needle to rotate; the shell assembly comprises an outer shell and a C-shaped seat, a containing groove is formed in the outer shell, and the speed regulating gear and the bevel gear part are arranged in the containing groove; the C-shaped seat extends towards the interior of the containing groove to be provided with an extension plate, and the speed adjusting knob is installed on the extension plate in a sliding mode in the transverse direction. According to the hydraulic speed regulation structure of the hidden hinge, the defect that the buffering speed of an existing hidden hinge is inconvenient to regulate is overcome.
