[0032] Reference below Figure 1-Figure 3 The invention describes an easily pluggable AC power cord plug according to an embodiment of the utility model.

[0033] like Figure 1-Figure 3 As shown, the easy-to-plug AC power cord plug includes a cable 100, a plug 200 and a tail plug (not shown in the figure). One end of the cable 100 is connected to the plug 200, and the other end is connected to the tail plug. The structure type of the tail plug adopts a corresponding structure according to the actual structure of the electrical equipment.

[0034] The plug 200 includes a plug-in portion 210 and a connecting portion 230. The surface of the plug-in portion 210 is flat and has a raised three-pin pole piece 120. The top of the three-pin pole piece 120 is a grounding pole piece, and the two pole pieces at the bottom are positive and negative pole pieces. The flat surface of the plug-in portion 210 can make the plug-in portion 210 fit better with the socket and the plugging is more stable.

[0035] One end of the connecting portion 230 is integrally formed with the plug-in portion 210, and the other end is connected to the cable 100. The surface of the plug-in portion 210 is concave inwardly to form a sliding groove 211 corresponding to the area between the ground wire and the positive and negative electrodes of the tripod pole piece 120. A push lever 220 is slidably connected in the sliding groove 211. The push lever 220 is provided with an inclined top portion 221 at both ends, and the inclined top portion 221 protrudes from the surface of the plug-in portion 210. Specifically, the sliding groove 211 passes through the side wall of the plug-in portion 210 horizontally, and the push lever 220 slides in the sliding groove 211, thereby driving the inclined top portion 221 to slide.

[0036] When the push lever 220 is pushed to slide, the inclined top portion 221 is inserted into the connection gap between the plug-in portion 210 and the socket to lift up the plug-in portion 210, thereby loosening and separating the plug-in portion 210 from the socket. Specifically, after the plug 200 is plugged into the socket, the socket and the plug-in portion 210 fit together, and at this time, the inclined top portion 221 is located on the two side walls of the plug-in portion 210. When the user needs to unplug the plug-in portion 210, first push the inclined top portion 221 left and right to insert the inclined top portion 221 between the plug-in portion 210 and the socket, and push the push lever 220 to reciprocate multiple times to make the inclined top portion 221 constantly lift up the plug-in portion 210, thereby gradually increasing the fitting gap between the plug-in portion 210 and the socket, reducing the clamping force of the socket on the tripod pole piece 120, and facilitating the user to unplug.

[0037] The easy-to-plug AC power cord plug of the utility model is mainly used for specific groups of people or specific use environments. When the plug 200 is plugged into the socket and is located in a narrow space, such as a TV wall, a sofa wall or a cabinet wall, it is inconvenient for the user to put a hand into the plug 200 and apply a force perpendicular to the socket to pull out the plug 200. At this time, the plug 200 can be loosened by pushing the lever 220 and the inclined top 221, so that it is easy to pull out.

[0038] For young or old users, due to their decreased body balance, the user's body balance is easily lost at the moment of pulling out the tightly connected three-pin plug 200, and there is a risk of falling backwards or standing unsteadily. The easy-to-plug AC power cord of the utility model can prevent accidents of special people when using the plug 200. Although it takes more time to pull out the plug 200 than the existing plug 200, the safety and convenience are improved, and it is suitable for installation in nursing homes, kindergartens, special care rooms and other places of use.

[0039] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a slider (not shown in the drawings) is provided on the side wall of the rod body of the push lever 220, and the inner wall of the sliding groove 211 is engaged with the slider of the push lever 220 to prevent the push lever 220 from being separated from the sliding groove 211. The structure in which the sliding member is slidably connected in the sliding groove 211 through the slider is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0040] Specifically, a limit block (not shown in the drawings) is further provided at the end of the sliding groove 211, and the limit block can prevent the push lever 220 from being disengaged from the sliding groove 211, and is used to limit the left and right sliding stroke of the push lever 220. In order to reduce the processing cost, the push lever 220 of this embodiment is not equipped with a return spring. When the user inserts the plug 200 into the socket, he needs to hold the push lever 220 with both hands to make it in the middle position to ensure that the plug 200 is fully plugged into the socket.

[0041] Further, if Figure 1-Figure 3 As shown, the middle part of the push lever 220 is made of hard plastic, the positions where the two ends of the push lever 220 are connected to the inclined top 221 are made of elastic rubber material, and the inclined top 221 is made of hard plastic. Specifically, since the inclined top 221 needs to be deformed during the plugging process to prevent it from hindering the connection between the plug 210 and the socket, a soft connection is used between the inclined top 221 and the push lever 220, and when the plug 200 is plugged into the socket, the inclined top 221 can be deformed in the opposite direction.

[0042] Further, if Figure 1 and Figure 3 As shown, the bottom of the two inclined top portions 221 of the sliding groove 211 is provided with a receiving groove 211a. When the plug-in portion 210 is plugged into the socket, the inclined top portion 221 is pushed into the receiving groove 211a. When the push lever 220 slides and the inclined top portion 221 enters the sliding groove 211, the inclined top portion 221 pushes up the gap between the end surface of the plug-in portion 210 and the socket. Specifically, the receiving groove 211a is used to receive the deformed inclined top portion 221. When the inclined top portion 221 enters the sliding groove 211 from the receiving groove 211a, the inclined top portion 221 squeezes into the connection gap between the plug-in portion 210 and the socket.

[0043] Further, if Figure 1-Figure 3 As shown, the inclined top portion 221 extends toward the direction of the tripod pole piece 120. It is ensured that the inclined top portion 221 can expand the gap between the plug-in portion 210 and the socket.

[0044] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the width of the push lever 220 is greater than the width of the plug-in portion 210, and the two oblique tops 221 protrude from the two side walls of the plug-in portion 210. Specifically, the push lever 220 protrudes from the two side walls of the plug-in portion 210 to prevent the user from pushing the push lever 220 into the sliding slot 211 and being unable to take it out.

[0045] In some embodiments of the present invention, Figure 1 As shown, the two side walls of the connection part 230 are provided with anti-skid textures 231, and the anti-skid textures 231 are protruding from the side walls of the connection part 230. Specifically, the anti-skid textures 231 can increase the friction between the user and the connection part 230, making it easier to pull out.

[0046] In some embodiments of the present invention, Figure 1 As shown, a power-assisting gripping block 232 is provided at the top of the connecting portion 230 corresponding to the anti-slip texture 231 , and the power-assisting gripping block 232 is used to facilitate the user to hold the plug 200 when unplugging it.

[0047] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, an anti-stretching sheath 110 is provided between the connecting portion 230 and the cable 100. The anti-stretching sheath 110 is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0048] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0049] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
