Abstract
The invention discloses a three-pin plug. A pressing device is arranged in the center of the three-pin plug, and comprises a pressing handle and two pressing rotating pins; the pressing handle comprises a pressing flat round head and a square pressing straight bar perpendicular to the pressing flat round head; the pressing rotating pins are L-shaped; one end of the pressing straight bar is connected with one end of each pressing rotating pin in an articulated manner; a square through hole which can allow the pressing straight bar to pass but not to be rotated is formed in the center of the three-pin plug; strip-shaped pressing grooves are formed in a pin surface of the three-pin plug on the two sides of the through hole; and the pressing grooves can contain the pressing rotating pins and are perpendicular to a power line hole of the three-pin plug, so that the three-pin plug can be propped pushed away from a socket by pressing the pressing handle, and can be manually pulled up easily. The three-pin plug is simple in structure, easy to process and manufacture, lower low in cost, convenient and safe.
Description
Technical field
The invention relates to a kind of commodity, more particularly, it is about three-pin plug.
Background technology
Present appliance plug, electrical equipment three-pin plug particularly, all tighter after inserting socket, be not drawn out easily, particularly plug is inserted in while not having in fixing socket, extract and must pin on the other hand socket, unplugg needs two hands to exert oneself simultaneously on the other hand, and this will make troubles to holding on the other hand when other article or proficiency are inconvenient to use, so can mention so far, also not have one hand just can will be inserted in the device that does not have the three-pin plug in fixing socket easily to extract.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, and a kind of three-pin plug is provided.
The object of the invention is to be achieved by following proposal:
Three-pin plug of the present invention, the center of three-pin plug is provided with press device, described press device comprises that pressing handle and two presses and turn pin, the described handle of pressing comprises by flattened round end and the vertical with it square straight-bar of pressing, described pressing turns pin for " L " shape, described press straight-bar one end with two to press the one end that turns pin be that hinge type is connected, the center of described three-pin plug be provided with can make to press straight-bar by but not revolvable square through hole, the pin face of through hole both sides three-pin plug is provided with strip by indent, by indent, can hold to press and turn pin and vertical with the power line hole of three-pin plug.
Advantage of the present invention is:
1, simple in structure, be easy to make;
2, use safe, with low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the cutaway top view of Fig. 1;
Fig. 2-1st, the structural representation of press device of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
As Fig. 1, three-pin plug of the present invention shown in 2, the center of three-pin plug A is provided with press device, as shown in Fig. 2-1, press device comprises that pressing handle and two presses and turn pin C, pressing handle comprises by flattened round end B1 and the vertical with it square straight-bar B2 that presses, described pressing turns pin C for " L " shape, press straight-bar B2 one end with two to press the one end that turns pin C be that hinge type is connected, namely two press turn pin C with press straight-bar B2 can be relative to rotating up and down centered by junction, the center of three-pin plug A be provided with can make to press straight-bar B2 by but not revolvable square through hole, the pin face of through hole both sides three-pin plug A is provided with strip by indent H, by indent H, can hold to press and turn pin C and vertical with the power line hole of three-pin plug A, by the indent H degree of depth and " L " shape, press that to turn the height of pin C suitable, being convenient to like this three-pin plug A inserts socket completely and is not pressed and turn the impact of pin C, in the time will pulling up plug, as long as press by flattened round end B1, at this moment pressing straight-bar B2 just moves downward, press for two and turn pin C and press one end that straight-bar B2 is connected and just move downward, " L " shape is pressed the reaction force that the crooked right angle electrical that turns pin C will be subject to socket, so press at this moment, turn the pin C other end with regard to the top three-pin plug A pin face that makes progress, thereby three-pin plug A item is opened to socket, this is that to turn the height of pin C forever short than limit because " L " square is pressed, so can reach easy jack-up plug, and then the easy object that manually pulls up plug, pressing handle can be made of plastics, press and turn pin C and can be made by rigid plastics or hard metal material.
