发明名称 Impact-resistant barrel assembly for a lens device
摘要 A barrel assembly for a lens device includes a stationary barrel, first and second barrel components, and a coupling pin. The stationary barrel surrounds an axis and has a first surface, and a second surface opposite to the first surface, and a guide slot formed through the first and second surfaces. The first barrel component engages sleevingly the stationary barrel and has a third surface. The second barrel component engages sleevingly the stationary barrel, and has a fourth surface that faces the second surface, and a cam slot that is formed in the fourth surface, and that is cooperatively defined by first and second slide surfaces, and first and second abutting portions. The coupling pin extends radially from the first barrel component through the guide slot in the stationary barrel to the second barrel component, and has a retaining section slidable along the first and second slide surfaces, and a reinforcing section extending between the first and second abutting portions.
