铰链

铰链是一种机械部件，使两个部分之间能够旋转运动，通常由销钉连接的两个叶片组成。在储物箱和整理器中，铰链提供盖子、门或面板的受控开合，同时保持结构对齐和载荷分布。工业铰链设计用于耐用性、精确运动控制以及在反复循环下的耐磨性。

铰链基于旋转运动学原理工作，其中两个叶片围绕公共轴线（销钉）旋转。销钉分配剪切力，同时允许扭矩传递。在储物应用中，铰链在开合循环期间保持力矩平衡，摩擦表面（衬套或轴承）减少磨损。连续铰链提供全长支撑，而对接铰链提供带有可调张力机构的离散枢轴点。

Hinges operate on the principle of rotational kinematics, where two leaf plates rotate around a common axis (the pin). The pin distributes shear forces while allowing torque transmission. In storage applications, hinges maintain moment equilibrium during opening/closing cycles, with friction surfaces (bushings or bearings) minimizing wear. Continuous hinges provide full-length support, while butt hinges offer discrete pivot points with adjustable tension mechanisms.
