Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hardware accessories, in particular to a furniture door hinge buffer. Background Art
[0002] Furniture door hinges generally include a hinge cup fixed on the door panel, a hinge seat assembly fixed on the cabinet frame, and a transmission assembly that enables the hinge cup to open and close on the hinge seat assembly. In order to achieve a buffering effect during opening and closing, reduce noise generation, and protect furniture, most furniture door hinges currently have buffer dampers installed on the hinge seat assembly.
[0003] The buffer dampers used on furniture door hinges are mostly hydraulic dampers, which are mainly composed of a cylinder body, a push rod, and a piston. The push rod is located at one end of the cylinder body and is fixed to the piston, and the piston is provided with multiple through holes. When the furniture door hinge moves, the push rod will drive the piston to move in the rod body, so that the liquid on one side of the piston in the cylinder body will move from the through hole on the piston to the other side of the piston, and generate throttling resistance, thereby having a buffering effect on the movement of the hinge.
[0004] However, the resistance of the buffers currently used for furniture door hinges is mostly fixed and cannot be adjusted. The weights of door panels of different furniture vary greatly due to differences in size and material. The buffers that cannot adjust the resistance limit the use of door hinges on different furniture and need to be improved. Utility Model Content
