Safety gates for electrical outlets

A safety gate for selectively covering socket holes of an electrical outlet, the safety gate comprising:

• an upper slide plate comprising an upper recessed platform, an upper space, and an upper slant;
• a lower slide plate comprising a lower slant, a lower space, and a lower recessed platform;
• and
• a side slide plate comprising a side slant and a groove,
• wherein:
• the upper space and the lower space are configured to allow load plug pins to pass through, and the upper space and the lower space are spaced apart to correspond to a spacing interval of the load plug pins,
• the upper recessed platform is on a first side of the upper space and the upper slant is on an opposed side of the upper space,
• the lower slant is on a first side of the lower space and the lower recessed platform is on an opposed side of the lower space,
• a slope of the upper slant and a slope of the lower slant are in the same direction,
• the upper slide plate is stacked with the lower slide plate such that the upper recessed platform overlaps with the lower slant and the upper slant overlaps with the lower recessed platform,
• at least one of the lower slant or upper slant corresponds to a long slot-shaped socket hole,
• at least one of the upper recessed platform or the lower recessed platform further comprises a protruding check block,
• the upper slide plate is configured to slide relative to the lower slide plate, and the lower slide plate is configured to slide relative to the upper slide plate,
• the slope of the upper slant and the slope of the lower slant are configured to interact with the load plug pins such that the load plug pins slide along the slopes to slidingly displace each of the upper slide plate and the lower slide plate a sliding distance in a direction away from the side slide plate, and the sliding distance for each of the upper slide plate and the lower slide plate is no less than a thickness of a load plug pin,
• the groove of the side slide plate abuts the protruding check block,
• the side slide plate is configured to slide in a direction perpendicular to a direction of relative sliding of the upper slide plate and the lower slide plate, and
• at least one of the upper slant or the lower slant is higher than the side slant so that when at least one of the upper slant or the lower slant interacts with a pin of the load plug, the at least one of the upper slant or the lower slant moves the protruding check block away from the groove.
