[0037] An automatic interlocking safety door for electrical outlets includes an upper housing, a safety door, a middle housing, and a lower housing. The upper housing has a through hole in the middle. The safety door is located at the through hole, and a slider is provided on the outer edge of the safety door. The safety door has a first insertion hole, and a limit groove is provided on the lower surface of the safety door at the first insertion hole. The middle housing is located below the upper housing and has a reset stop corresponding to the position of the limit groove. A sliding groove is provided on the edge of the upper or middle housing at the through hole, and the shape and position of the slider correspond to the shape and position of the sliding groove. The length of the slider is shorter than the length of the sliding groove. The lower housing is located below the middle housing and has a fixing device corresponding to the socket. Both the middle and lower housings have second insertion holes, and the first insertion hole and the second insertion hole are offset from each other.

[0038] Because the lower casing is equipped with a fixing device corresponding to the socket, the entire automatic hole-closing interlocking safety door can be directly fixed to the socket through the fixing device. This allows users to solve the safety problem of the socket simply by adding an automatic hole-closing interlocking safety door to a traditional socket, reducing the difficulty and cost of modifying traditional sockets, improving the competitiveness of the product, increasing users' willingness to modify, and reducing safety hazards for children. At the same time, the safety door not only serves a safety function, but also provides waterproof, oil-proof, and dustproof functions.

[0039] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] Example 1, please refer to Figures 1 to 9This utility model provides an automatic interlocking safety door for power outlets, comprising an upper housing 1, a safety door 2, a middle housing 3, and a lower housing 4. The upper housing 1 has a through hole 11 in the middle. The safety door 2 is located at the through hole 11, and a slider 21 is provided on the outer edge of the safety door 2. A first insertion hole 22 is provided on the safety door 2, and a limit groove 23 is provided on the lower surface of the safety door 2 located at the first insertion hole 22. The middle housing 3 is located below the upper housing 1, and a reset stop 31 is provided on the middle housing 3. The position of the reset stop 31 is related to the limit. Corresponding to the position of the groove 23, a sliding groove 32 is provided on the edge of the upper housing 1 or the middle housing 3 located at the through hole 11. The shape and position of the slider 21 correspond to the shape and position of the sliding groove 32, and the length of the slider 21 is shorter than the length of the sliding groove 32. The lower housing 4 is located below the middle housing 3. The lower housing 4 is provided with a fixing device 5 corresponding to the socket. A second insertion hole 33 is provided on both the middle housing 3 and the lower housing 4. The first insertion hole 22 and the second insertion hole 33 are offset, that is, when reset, the first insertion hole 22 and the second insertion hole 33 are not aligned.

[0041] Before use, fix the automatic interlocking safety door of the electrical outlet to the socket, ensuring that the second socket 33 is aligned with the socket on the socket. When in use, insert the plug into the first through hole 11 on the safety door 2 and press down the reset stop 31, causing it to disengage from the limiting groove 23. This allows the safety door 2 to move back and forth. After the safety door 2 moves, when the first socket 22 aligns with the second socket 33, the plug can be inserted into the second socket 33 and then into the socket, thus establishing electrical connection between the plug and the socket. When the plug is removed, reset the safety door 2, causing the reset stop 31 to pop out and lock into the limiting groove 23, causing the first socket 22 and the second socket 33 to shift. At this point, the plug inserted into the first socket 22 cannot contact the second socket 33 or the socket on the socket, thus preventing children from directly inserting their fingers into the socket and getting an electric shock, ensuring child safety.

[0042] This utility model is specifically designed to address the safety hazards inherent in traditional household electrical outlets. Because the lower housing 4 is equipped with a fixing device 5 corresponding to the outlet, the automatic interlocking safety door for the electrical outlet can be directly fixed to the outlet via the fixing device 5. This allows users to solve the safety problem of traditional outlets simply by adding the automatic interlocking safety door, reducing the difficulty and cost of modifying traditional outlets, improving product competitiveness, increasing users' willingness to modify their outlets, and reducing safety hazards for children. Furthermore, the safety door 2 not only provides safety but also serves as a waterproof, oil-proof, and dustproof barrier.

[0043] Of course, the first socket 22 and the second socket 33 of the automatic interlocking safety door with power outlet can be two-hole, three-hole, or five-hole, and all of them should fall within the protection scope of this utility model.

[0044] Example 2, please refer to Figures 1 to 9 As a further optimization of Embodiment 1, in this embodiment, the fixing device 5 is a copper foot, which is fixed on the lower housing 4. In use, the copper foot is inserted into the socket hole to achieve the fixing between the automatic hole closing interlock safety door and the socket. Since the automatic hole closing interlock safety door has a certain thickness, if the copper foot is not used to connect with the socket, the traditional plug may not be able to connect with the socket due to its short length. However, by using the copper foot in this embodiment, the problem of the plug being too short can be solved. That is, the connection is first made with the socket through the copper foot, and then the connection is made with the copper foot through the plug to ensure smooth connection.

[0045] In other embodiments, the fixing device 5 can also be a double-sided adhesive set on the lower surface of the lower housing 4. After the double-sided adhesive is attached and fixed to the socket, and its second socket 33 is aligned with the socket, the automatic interlocking safety door for the power outlet can be used normally. The automatic interlocking safety door for the power outlet provided by this utility model is small, lightweight, and inexpensive, which can greatly improve the competitiveness of the product.

[0046] Furthermore, the safety door 2 is transparent in color and made of transparent acrylic sheet, which allows users to see at a glance whether the safety door 2 is good or bad, so that users can replace the automatic interlocking safety door for the power outlet in a timely manner, avoid children accidentally touching it and causing danger, and protect children's safety.

[0047] Furthermore, the copper feet are wavy in shape so that they can be securely fastened to the socket and ensure electrical conductivity between the copper feet and the socket.

[0048] Furthermore, both slider 21 and slide groove 32 are either straight or arc-shaped. When slider 21 and slide groove 32 are straight, safety door 2 is also rectangular, allowing it to slide back and forth in a straight line. When slider 21 and slide groove 32 are arc-shaped, safety door 2 is also circular, allowing it to rotate clockwise or counterclockwise.

[0049] Furthermore, a placement groove 34 is provided on the middle shell 3, and an elastic reset device 35 is installed in the placement groove 34. A fixing post 24 is provided on the lower surface of the safety door 2, and the elastic reset device 35 is sleeved on the fixing post 24. When the slider 21 and the slide groove 32 are both linear in shape, the elastic reset device 35 is a spring. When the slider 21 and the slide groove 32 are both arc-shaped, the elastic reset device 35 is a torsion spring. The elastic reset device 35 can make the safety door 2 automatically reset, further improving the safety of the product.

[0050] Furthermore, the limiting groove 23 is located on one side of the starting position of the safety door 2, and the reset stop 31 includes a stop and a spring sleeved on the stop, so that the reset stop 31 can be reset after the safety door 2 is reset.

[0051] Please see Figure 10 The present invention provides a safety socket, which includes a socket and an automatic interlocking safety door for power outlets as described in any of the above claims. The fixing device 5 is fixed on the socket, and the position of the socket hole corresponds to the position of the second socket 33. This type of socket can be implemented using a traditional socket without the need for significant modifications to the safety socket.

[0052] Of course, it can also be applied to other electrical devices such as power strips, and all of them should fall within the protection scope of this utility model.

[0053] Please see Figure 11 Furthermore, the socket has a groove, and an automatic hole-closing interlock safety door is installed in the groove. The upper surface of the safety door 2 is flush with the upper surface of the socket. This structure can reduce the thickness of the product, but requires a specially made safety socket.

[0054] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0055] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments.
