Abstract: A pivoting assembly with a positioning function includes a base and a casing assembled with the base. The base is provided with curved elastic arms and two fixing supports. Each fixing support has a pivotal hole. One surface of the casing is formed with a curved portion for allowing the curved elastic arm to abut against and two holes for allowing the fixing support to pass through. The other surface of the casing is formed with a protrusion pivotally connected to the pivotal hole. When the curved portion slides on the curved elastic arm, elastic abutment between the curved portion and the curved elastic arm makes the casing to be positioned by friction fit with respect to the base. By this structure, the present invention can be positioned without a positioning pin or bolt. Further, the present invention is simple in structure, easy to assemble and low in production cost.

Abstract translation: 具有定位功能的枢转组件包括底座和与底座组装的壳体。 基座设有弯曲的弹性臂和两个固定支架。 每个固定支撑件具有枢转孔。 壳体的一个表面形成有用于允许弯曲的弹性臂抵靠的弯曲部分和用于允许固定支撑件通过的两个孔。 壳体的另一个表面形成有枢转地连接到枢转孔的突起。 当弯曲部分在弯曲弹性臂上滑动时，弯曲部分和弯曲弹性臂之间的弹性邻接使得壳体相对于基座摩擦配合而定位。 通过这种结构，可以在没有定位销或螺栓的情况下定位本发明。 此外，本发明结构简单，易于组装，生产成本低。
