Outlet device

Abstract

An outlet device for hanging on a plate includes a counterweight portion, a hanging portion arranged distant from the counterweight portion, an extending portion having two ends respectively connected to the counterweight portion and the hanging portion, and a power core connected to the counterweight portion. Each of the counterweight portion and the hanging portion has an outlet unit electrically connected to the power core. The outlet device is configured so that the counterweight portion is arranged under the plate and the hanging portion is arranged on the plate, and the hanging portion remains hung on the plate by using the weight distribution of the outlet device, thereby maintaining the outlet device in a static balance state.

What is claimed is: 
     
         1 . An outlet device for being hung on a plate, comprising:
 a counterweight portion including a first outlet unit;   a hanging portion arranged distant from the counterweight portion and including a second outlet unit;   an extending portion having two opposite ends respectively connected to the counterweight portion and the hanging portion, wherein a free end of the hanging portion is arranged distant from the extending portion by a lateral distance, the extending portion has a width parallel to the lateral distance, and the width is less than or equal to the lateral distance; and   a power cord electrically connected to the first outlet unit and the second outlet unit, wherein the power cord has an end connected to the counterweight portion and an opposite end used for detachably inserting into an external power supplying outlet,   wherein the outlet device is configured so that the counterweight portion is arranged under the plate and the hanging portion is arranged on the plate, and the hanging portion remains hung on the plate by using the weight distribution of the outlet device, thereby maintaining the outlet device in a static balance state.   
     
     
         2 . The outlet device as claimed in  claim 1 , wherein the counterweight portion includes a first case, the first outlet unit is disposed in the first case, the hanging portion includes a second case, the second outlet unit is disposed in the second case, the extending portion includes a third case, the third case has a first end and an opposite second end, and the first end and the second end are respectively and perpendicularly connected to the first case and the second case. 
     
     
         3 . The outlet device as claimed in  claim 2 , wherein the first end and the second end of the third case are integrally connected to the first case and the second case, and the first case, the second case, and the third case surround to form a U-shaped hanging slot for receiving a part of the plate. 
     
     
         4 . The outlet device as claimed in  claim 3 , further comprising a limiting structure movably disposed on the first case, wherein the limiting structure is arranged in the U-shaped hanging slot for abutting against the plate. 
     
     
         5 . The outlet device as claimed in  claim 4 , wherein the limiting structure includes an abutting member and an elastic member, an end of the abutting member is disposed on the first case by cooperating with the elastic member, and an opposite end of the abutting member is arranged apart from the first case by a vertical distance, and wherein when the abutting member is pressed to cause reduction of the vertical distance, the elastic member stores an elastic force tending to recover the vertical distance. 
     
     
         6 . The outlet device as claimed in  claim 4 , wherein an accommodating slot is recessed in an inner surface of the first case and is in air communication with the U-shaped hanging slot, and the limiting structure is movable toward the accommodating slot when being pressed. 
     
     
         7 . The outlet device as claimed in  claim 2 , wherein the first end of the third case is movably connected to the first case, and the second end of the third case is integrally connected to the second case. 
     
     
         8 . The outlet device as claimed in  claim 7 , wherein the first case having an elongated shape defines a longitudinal direction perpendicular to the lateral direction and the width. 
     
     
         9 . The outlet device as claimed in  claim 3 , wherein a corner of the first case arranged distant from the third case has a notch, and the power cord is rotatable to be arranged in the notch of the first case. 
     
     
         10 . An outlet device, comprising:
 a counterweight portion including a first outlet unit, and the first outlet unit including at least one AC power outlet;   a hanging portion arranged distant from the counterweight portion and including a second outlet unit, wherein the second outlet unit includes at least one DC power outlet, and an opening of the at least one DC power outlet is formed on a surface of the hanging portion arranged distant from the counterweight portion; and   an extending portion having two opposite ends respectively connected to the counterweight portion and the hanging portion, wherein the extending portion is provided without any outlet unit, a free end of the hanging portion is arranged distant from the extending portion by a lateral distance, the extending portion has a width parallel to the lateral distance, and the width is less than or equal to the lateral distance.
