Description

Technical Field

[0001] The utility model belongs to the technical field of cabinet hinge devices, and specifically relates to hinge devices. Background Technology

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow them to rotate relative to each other. A hinge is generally composed of a transmission component and is suitable for installation on cabinets and furniture door panels.

[0003] According to the installation type, the existing hinge devices can be divided into two types: fixed and removable. This also determines the classification and structural differences of the hinge base. Nowadays, the base structure of fixed hinge devices is similar, usually including a base, screw mounting holes, and U-slots. Some will also use reinforcing rib structures or convex humps to increase the strength of the fixed base to prevent load-bearing deformation.

[0004] When a solid metal damper (also known as a cylinder) is used in a fixed hinge device, the drilling process of the tail hole of the cylinder cannot meet the hole size within the normal tolerance range, and the inner cavity of the base bending is emptied without obstruction. When the hinge device opens and closes, the cylinder will swing and make a metal collision sound with the base, causing abnormal noise problems on the door panel, or even noise pollution, which brings a bad experience to users. Contents of utility model
