POWER PLUG DEVICE AND LINKAGE MECHANISM THEREOF

摘要

A power plug device includes a casing, a first prong, a second prong, and a linkage mechanism. The first and second prongs are pivotally arranged in a receiving recess of the casing. The linkage mechanism includes a linkage member, a first link, and a second link. A first end of the first link and a first end of the second link are respectively connected to the first and second prongs. A second end of the first link and a second end of the second link are both disposed in a guiding groove of the linkage member. When the first prong rotates, the second end of the first link can move in the guiding groove to drive the second end of the second link through the linkage member to move inversely in the guiding groove, such that the second prong rotates inversely with respect to the first prong.

主权项

1. A power plug device, comprising:
a casing, an outer face of the casing formed with a receiving recess; a first prong and a second prong, the first prong and the second prong each pivotally arranged in the receiving recess respectively through pivotal connections between the bottom end of the first prong and the casing and between the bottom end of the second prong and the casing, and a linkage mechanism disposed inside the casing, the linkage mechanism comprising:
a linkage member having a guiding groove;a first link, a first end of the first link being fixed to the bottom end of the first prong, and a second end of the first link being disposed in the guiding groove; anda second link, a first end of the second link being fixed to the bottom end of the second prong, and a second end of the second link being disposed in the guiding groove; wherein when the first prong rotates relative to the casing, the second end of the first link slides in the guiding groove, the linkage member is driven to move, and the second end of the second link is in turn driven to slide in the guiding groove in the opposite direction as the second end of the first link slides, causing the second prong to rotate in the opposite direction as the first prong does.
