Electric plug
The present invention relates to an electric plug comprising: a body part including a reception part; a pin inserted in and fixed to one surface of the body part; and a detachment part included in the reception part, wherein the detachment part comprises a gear stick and a handle part rotating while being engaged with the gear stick. Therefore, the present invention enables a user to separate an electric plug tightly plugged in an outlet from the outlet even by tiny force.
1. An electric plug, comprising:
a body part including a reception part, which is formed to be concave, an upper opening part communicating with the reception part and having a top surface portion, which is opened, a lower opening part communicating with the reception part and having a bottom surface portion, which is opened, and one pair of pins for electric connection, which are extended downwards from the bottom surface of the body part;
a gear stick having a gear part formed at the center portion thereof, and provided to be movable in the vertical direction in the reception part so as to be exposed out of the lower portion of the body part through the lower opening part; and
one pair of handle parts provided in the reception part, having serrated parts engaged with the gear part, supported so as to rotate with respect to a support pin arranged at both side surfaces of the gear stick, and exposed out of the upper portion of the body part through the upper opening part at the upper portions thereof;
wherein, if the handle parts are rotated such that the upper end portions of the handle parts, which are exposed out of the upper portion of the body part, are close to each other, the gear stick moves downwards through the gear part, which is engaged with the serrated parts, and the lower end portion of the gear stick presses the top surface of an outlet, thereby acting as force which allows the plug to be detached from the outlet.
2. The electric plug according to claim 1 , wherein the gear stick has support parts extended outwards from the center portion of the gear stick such that the gear stick can slide on the inner surface of the lower opening part in a state, in which the outer ends of the support parts are in contact with the inner surface of the lower opening part.
3. The electric plug according to claim 2 , wherein the lower opening part has holding protrusions formed on the inside thereof so as to hold the support parts, thereby limiting the downward movement of the gear shaft.
