Description
Technical Field
[0001] The present invention relates to the technical field of safe electricity use, and in particular to a safe electricity extraction device. Background Art
[0002] Electricity is an indispensable energy source in modern life, and household electrical appliances can only work normally after they are powered. In order to facilitate power supply, a socket is generally provided on the wall to supply power to the electrical appliances. At present, the sockets on the market mainly include a shell, a socket is provided on the shell, a circuit structure is installed in the shell, and electrodes are provided in the socket. When the plug of the electrical appliance is inserted into the socket, power supply can be completed. Such a socket is generally in an open state, or only an elastic baffle is provided in the socket. For children, they are curious and lively. If a child holds a metal object (such as stainless steel chopsticks, etc.) and inserts it into the socket, there will be a risk of electric shock. In addition, the existing plug often achieves conductivity as long as it contacts the socket (that is, the plug is not plugged in at this time). If there are problems such as rust and corrosion at the front end of the plug, it is easy to cause poor contact with the socket, thereby bringing certain safety hazards. Summary of the invention

[0017] Furthermore, the first end of the locking rod is hinged to the rotating plate via a pin.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] (1) In the setting mode of the plug, the two reset springs are suitable for applying elastic force to the two power-taking poles to move them closer to each other so as to separate the two power-taking poles from the two power-taking abutments; so when the power-taking terminals of the plug just contact the conductive clips of the socket, the enlarged head of the slider is located inside the shell, while the other parts are located outside the shell, and at this time the external wire is not connected to the power-taking pole; and when the power-taking terminals of the plug are fully inserted into the conductive clips of the socket, the end of the slider away from the enlarged head will abut against the cover plate of the safety cover, that is, the slider moves toward the inside of the shell during this process, and the deformable part will be squeezed and then expanded during this process, thereby driving the two power-taking poles away from each other until they abut against the power-taking abutments, and at this time the external wire will be connected to the power-taking pole. It can be seen from the above process that the plug will only be energized after the power-taking terminals of the plug are fully inserted into the conductive clips of the socket, thereby avoiding the safety hazard caused by poor contact at the front end of the power-taking terminals of the plug.
[0020] (2) In the arrangement of the socket, the two elastic members are suitable for applying elastic forces to the two conductive rods to move away from each other so as to separate the two conductive rods from the two conductive clips; therefore, when the shell of the plug is not accommodated in the recess of the shell, the second ends of the rotating member will not approach each other, and the two conductive clips will not be energized; and when the shell of the plug is accommodated in the recess of the shell, the first end of the rotating member passing through the perforation will be pushed back into the shell by the shell, and accordingly, the second ends of the rotating member will approach each other, thereby pushing the two conductive rods to abut against the two conductive clips, and the two conductive clips will be energized. It can be seen from the above process that the two conductive clips will only be energized after the shell of the plug is accommodated in the recess, so when the shell is not accommodated in the recess, even if a child holds a metal object and inserts it into the conductive clip, there will be no risk of electric shock, thus ensuring the safety of electricity use.
[0021] (3) In the setting mode of the safety cover, the guide plate is suitable for covering a part of the first socket, and the protrusion is suitable for covering another part of the first socket, so it is equivalent to that the socket hole is sealed, which plays a role in dust prevention and also has a certain safety. And because the protrusion is suitable for snapping into the other part of the first socket, when the power terminal is inserted toward the first socket, the protrusion will be pushed away from the other part of the first socket, which is equivalent to unlocking the rotating plate through the power terminal so that it can rotate. It should be noted that there are two first sockets and two protrusions matching the first sockets, so the rotating plate will be unlocked only when two power terminals are inserted at the same time; if only one power terminal is inserted, there is always a protrusion snapping into the first socket, so that the rotating plate is in a non-rotatable state, thereby eliminating the possibility of children inserting metal objects into the socket, ensuring safety.

Specifically, the elastic member 24 is a spring.
[0037] Reference Figure 1 , Figure 3 , Figure 4-5 , Figure 4-8 The safety cover 300 is arranged above the bottom surface of the recessed portion 21; the safety cover 300 includes a cover plate 31 and a rotating plate 32; the rotating plate 32 is located between the bottom surface of the recessed portion 21 and the cover plate 31; the rotating plate 32 can be rotatably connected to the cover plate 31, and a first torsion spring is arranged between the rotating plate 32 and the cover plate 31; the cover plate 31 is provided with a first socket 311 for the power terminal 11 to pass through, and the first socket 311 and the socket 211 are located on the same straight line; the rotating plate 32 is provided with a second socket 321, and the edge of the second socket 321 is provided with a guide plate 322 inclined toward the bottom surface of the recessed portion 21, and the guide plate 322 is suitable for covering a part of the first socket 311; the rotating plate 32 is also provided with a locking rod 33 The first end of the locking rod 33 is hinged to the rotating plate 32, and a protrusion 331 facing the cover plate 31 is arranged on the second end of the locking rod 33. A second torsion spring is arranged between the locking rod 33 and the rotating plate 32. The second torsion spring is suitable for applying an elastic force toward the cover plate 31 to the second end of the locking rod 33. The protrusion 331 is suitable for covering another part of the first socket 311, and the protrusion 331 is suitable for being clamped in another part of the first socket 311; when the power terminal 11 is inserted toward the first socket 311, it is suitable for pushing the protrusion 331 away from another part of the first socket 311, and at the same time, the rotating plate 32 is driven to rotate through the guide plate 322 to expose the first socket 311, and the power terminal 11 is suitable for passing through the second socket 321. Specifically, the rotating plate 32 is circular. The first end of the locking rod 33 is hinged to the rotating plate 32 through a pin shaft.
[0038] In the above-mentioned setting mode of the plug 100, the two reset springs 14 are suitable for applying elastic force to the two power-taking poles 15 to move closer to each other so as to separate the two power-taking poles 15 from the two power-taking abutment members 13; so when the power-taking terminal 11 of the plug 100 just contacts the conductive clip 22 of the socket 200, the enlarged head 161 of the slider 16 is located inside the shell 1, while the other part is located outside the shell 1, and at this time the external wire 4 is not connected to the power-taking pole 15; and when the power-taking terminal 11 of the plug 100 is fully inserted into the conductive clip 22 of the socket 200, the end of the slider 16 away from the enlarged head 161 will abut against the cover plate 31 of the safety cover 300, that is, during this process the slider 16 moves toward the inside of the shell 1, and the deformable member 18 will be squeezed and then expanded during this process (such as Figure 3 and Figure 4 The two power-taking rods 15 are driven away from each other until they abut against the power-taking abutment member 13, and the external wire 4 is connected to the power-taking rod 15. From the above process, it can be seen that the plug 100 will be powered only after the power-taking terminals 11 of the plug 100 are fully inserted into the conductive clip 22 of the socket 200, thereby avoiding the potential safety hazard caused by poor contact of the front end of the power-taking terminals 11 of the plug 100.
[0039] In the above-mentioned arrangement of the socket 200, the two elastic members 24 are suitable for applying elastic forces to the two conductive rods 23 to move away from each other so as to separate the two conductive rods 23 from the two conductive clips 22; therefore, when the shell 1 of the plug 100 is not accommodated in the recessed portion 21 of the shell 2, the second ends of the rotating member 25 will not approach each other, and the two conductive clips 22 will not be energized; and when the shell 1 of the plug 100 is accommodated in the recessed portion 21 of the shell 2, the first end of the rotating member 25 passing through the through hole 212 will be pushed back into the shell 2 by the shell 1, and correspondingly, the second ends of the rotating member 25 will approach each other, thereby pushing the two conductive rods 23 to abut against the two conductive clips 22, and at this time, the two conductive clips 22 will be energized. It can be seen from the above process that only after the shell 1 of the plug 100 is accommodated in the recessed portion 21, the two conductive clips 22 will be energized, so when the shell 1 is not accommodated in the recessed portion 21, even if a child holds a metal object and inserts it into the conductive clip 22, there will be no danger of electric shock, thereby ensuring the safety of electricity use.
[0040] In the above-mentioned arrangement of the safety cover 300, the guide plate 322 is suitable for covering a part of the first socket 311, and the protrusion 331 is suitable for covering another part of the first socket 311, so it is equivalent to that the socket 211 of the socket 200 is sealed, which plays a role of dust prevention and also has a certain degree of safety. And because the protrusion 331 is suitable for snapping into the other part of the first socket 311, when the power terminal 11 is inserted toward the first socket 311, the protrusion 331 will be pushed away from the other part of the first socket 311, which is equivalent to unlocking the rotating plate 32 through the power terminal 11, so that it can rotate. It should be noted that there are two first sockets 311 and two protrusions 331 that match the first sockets 311. Therefore, the rotating plate 32 will be unlocked only when two power terminals 11 are inserted at the same time; if only one power terminal 11 is inserted, there is always one protrusion 331 that is engaged with the first socket 311, so that the rotating plate 32 is in a non-rotatable state, thereby preventing children from inserting metal objects into the socket 200. Specifically, refer to Figure 3 , Figure 4 ,as well as Figure 7-8 It should be noted that Figure 7 The middle rotating plate 32 can be obtained by rotating in the direction of the arrow. Figure 8 When the two power terminals 11 are inserted at the same time, the two protrusions 331 will be pushed away from the first socket 311 at the same time. At the same time, the power terminal 11 will act on the guide plate 322. Since the guide plate 322 is inclined toward the bottom surface of the recessed portion 21, the guide plate 322 will rotate, thereby driving the rotating plate 32 to rotate, and finally exposing the first socket 311, so that the power terminal 11 can smoothly pass through the first socket 311 and the second socket 321 to enter the socket 211 of the socket 200 to complete power collection.
[0041] In summary, the present invention eliminates the possibility of children inserting metal objects into the socket 211 through the cooperation of the plug 100 and the safety cover 300, while the plug 100 avoids the safety hazard caused by the poor contact of the front end of the power terminal 11 of the plug 100; overall, the power safety of the safety power supply device of the present invention is greatly improved.

With such a setting, the power taking pole 15 will always maintain electrical connection with the power taking terminal 11 during the rotation process. Of course, in addition to this method, the two can also be electrically connected through a flexible wire.
[0046] Preferably, the first end of the rotating member 25 is arc-shaped. The first end of the rotating member 25 is arc-shaped, which can ensure the smoothness of the housing 1 of the plug 100 entering the recessed portion 21 of the socket 200 and reduce the sense of obstruction.
[0047] Preferably, refer to Figure 1 The conductive clip 22 includes a first metal plate 221 and a second metal plate 223 arranged opposite to each other. A first metal spring 222 is arranged on the surface of the first metal plate 221 and the second metal plate 223 opposite to each other. A second metal spring 224 is arranged on the surface of the second metal plate 223 and the first metal plate 221 opposite to each other. Both the first metal spring 222 and the second metal spring 224 are convex arc-shaped.
