Description

Technical Field

[0001] The present invention relates to the technical field of electric connectors, and more particularly to a self-locking electric socket with a safety door. Background Art

[0002] In our daily lives, we often use power strips or sockets to connect and control the connection and disconnection of power. Although traditional power strips or sockets currently on the market are designed with safety devices, they still pose safety risks. They generally add a control switch to the power strip or socket. When electricity is needed, press the control switch and insert a plug to turn on the power. When electricity is not needed, turn off the control switch to cut off the power. Although this structure is safe enough when used correctly, in real life, people often do not turn off the control switch when not in use. When children turn on the switch again, or forget to turn off the control switch, babies or children may accidentally put their fingers into the socket and get electric shock. This structure cannot provide a safety effect and does not meet people's growing demand for electricity safety, and does not provide comprehensive safety protection.

[0003] Although some sockets adopt a safety door design, such as the Chinese patent application number CN201621262086.6 which discloses the "Safety Door Mechanism and European Socket", a rotating shaft is added to the safety door so that the safety door can be rotated to expose the two insertion holes before the plug and the socket can be connected. It can also play a certain protective role, but for infants or children, inserting and rotating the plug is still an easy operation to achieve, and there is still a risk of electric shock, and it still cannot get comprehensive safety protection. Summary of the Invention

[0004] The technical problem to be solved by the present invention is how to minimize the risk of electric shock while not hindering the convenience of electricity use, so as to provide comprehensive safety protection for children and infants.

[0005] The technical problem to be solved by the present invention is achieved through the following technical solutions:

[0006] In order to solve the above technical problems, the present invention provides a self-locking electrical socket with a safety door, which includes an upper shell, a lower shell, a safety door and a reset stop column, and the lower shell is arranged below the upper shell; there is at least one safety door, which is arranged on the upper shell and can be rotated clockwise and / or counterclockwise and reset on the upper shell, and each of the safety doors is provided with at least one socket; there is at least one reset stop column, which is fixed on the lower shell and extends to the socket, and when the reset stop column is not pressed, the reset stop column blocks the rotation path of the safety door and prevents the safety door from rotating, and when the reset stop column is pressed downward, it stays away from the rotation path of the safety door and allows the safety door to rotate.

[0007] As a preferred embodiment of the self-locking electrical socket with a safety door provided by the present invention, there are at least two sockets, the two sockets include at least a first socket and a second socket, there are two reset stop columns, the two reset stop columns include a first stop column and a second stop column, the first stop column is located on the upper side of the first socket, and the second stop column is located on the lower side of the second socket.

[0008] As a preferred embodiment of the self-locking electrical socket with a safety door provided by the present invention, the reset blocking column includes a blocking column and a spring sleeved on the blocking column.

[0009] As a preferred embodiment of the self-locking electrical socket with a safety door provided by the present invention, a middle shell is provided between the upper shell and the lower shell.

[0010] As a preferred embodiment of the self-locking electrical socket with a safety door provided by the present invention, a placement groove is provided on the middle shell, a torsion spring is provided in the placement groove, a torsion column is provided on the lower surface of the safety door, and the torsion spring is sleeved on the torsion column.

[0011] As a preferred embodiment of the self-locking electrical socket with a safety door provided by the present invention, a blocking column hole is opened on the middle shell, and the blocking column hole is sleeved on the reset blocking column.

[0012] As a preferred embodiment of the self-locking electrical socket with a safety door provided by the present invention, a boss is provided on the lower surface of the safety door located at the non-rotation center, and a limiting groove corresponding to the boss is provided on the middle shell.

[0013] As a preferred embodiment of the self-locking electrical socket with a safety door provided by the present invention, a base is provided below the lower shell, and a metal contact piece is fixed on the base.

[0014] As a preferred embodiment of the self-locking electrical socket with a safety door provided by the present invention, the cross-section of the safety door is circular.

[0015] As a preferred embodiment of the self-locking electrical socket with safety doors provided by the present invention, there are two safety doors, and the two safety doors include a first safety door and a second safety door. The first safety door is provided with two sockets, and the second safety door is provided with three sockets.

[0016] The present invention has the following beneficial effects:

[0017] During normal use, the plug is directly inserted into the socket and rotated before being inserted. When the plug is inserted, the outer end of the plug can press the reset stop post at the socket downward, causing the reset stop post to move away from the rotation path of the safety door, allowing the plug to drive the safety door to rotate. After rotating to a certain angle, it aligns with the insertion hole on the base, allowing the plug to be inserted into the insertion hole and contact the metal contact piece on the base. When the plug is unplugged, the safety door is reset, and the reset stop post is also reset after the safety door is reset, so that the safety door is locked. At the same time, the area of the reset stop post can be made very small, such as the cross-sectional area of the reset stop post is one-fifth of the area of the socket. This makes it difficult for infants or children to accurately insert the reset stop post when playing with other tools such as scissors or chopsticks, thus preventing the safety door from rotating. The self-locking function is also achieved. Even if these tools can be inserted into the reset stop post, it is difficult to rotate the safety door. This minimizes the risk of electric shock while not hindering the convenience of electricity use, thereby providing comprehensive safety protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0030] The present invention provides a self-locking electrical socket with a safety door, which includes an upper shell, a lower shell, a safety door and a reset stop column, wherein the lower shell is arranged below the upper shell; there is at least one safety door, which is arranged on the upper shell and can be reset by rotating clockwise and / or counterclockwise on the upper shell, and at least one socket is provided on the safety door; there is at least one reset stop column, which is fixed on the lower shell and extends to the socket, and when the reset stop column is not pressed, the reset stop column blocks the rotation path of the safety door and prevents the safety door from rotating, and when the reset stop column is pressed downward, it stays away from the rotation path of the safety door and allows the safety door to rotate.

[0031] During normal use, the plug is directly inserted into the socket and rotated before being inserted. When the plug is inserted, the outer end of the plug can press the reset stop post at the socket downward, causing the reset stop post to move away from the rotation path of the safety door, allowing the plug to drive the safety door to rotate. After rotating to a certain angle, it aligns with the insertion hole on the base, allowing the plug to be inserted into the insertion hole and contact the metal contact piece on the base. When the plug is unplugged, the safety door is reset, and the reset stop post is also reset after the safety door is reset, so that the safety door is locked. At the same time, the area of the reset stop post can be made very small, such as the cross-sectional area of the reset stop post is one-fifth of the area of the socket. This makes it difficult for infants or children to accurately insert the reset stop post when playing with other tools such as scissors or chopsticks, thus preventing the safety door from rotating. The self-locking function is also achieved. Even if these tools can be inserted into the reset stop post, it is difficult to rotate the safety door. This minimizes the risk of electric shock while not hindering the convenience of electricity use, thereby providing comprehensive safety protection.

[0032] In order 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 in conjunction with the accompanying drawings. The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be understood as limiting the present invention.

[0033] Example 1, please refer to Figures 1 to 5, a self-locking electrical socket with a safety door provided by the present invention, which includes an upper shell 1, a lower shell 2, a safety door 3 and a reset stop column 4, the lower shell 2 is arranged below the upper shell 1; there is at least one safety door 3, the safety door 3 is arranged on the upper shell 1 and can be rotated clockwise and / or counterclockwise on the upper shell 1 and reset, that is, the safety door 3 can be rotated clockwise or counterclockwise on the upper shell 1, or can be rotated clockwise or counterclockwise and can be reset after rotation, a base 5 is provided below the lower shell 2, an insertion hole is provided on the base 5, a metal contact piece 6 is fixed in the base 5 located at the insertion hole, and when it is factory set, the socket 31 on the safety door 3 is aligned with the socket 31 on the base 5 The metal contact pieces 6 are staggered, that is, the safety door 3 needs to be rotated a certain angle before the plug can be inserted into the metal contact piece 6. Each safety door 3 is provided with at least one socket 31. Under normal circumstances, two or three sockets 31 are correspondingly set for one safety door 3. Of course, in other cases, a corresponding number of sockets 31 can also be set as needed, which should all fall within the scope of protection of the present invention; there is at least one reset stop column 4, which is fixed on the lower shell 2 and extends to the socket 31. When the reset stop column 4 is not pressed, the reset stop column 4 blocks the rotation path of the safety door 3 and prevents the safety door 3 from rotating. When the reset stop column 4 is pressed downward, it stays away from the rotation path of the safety door 3 and allows the safety door 3 to rotate.

[0034] During normal use, directly insert the plug into the socket 31 and rotate the plug before inserting it. When inserting the plug, the outer end of the plug can press the reset stop column 4 at the socket 31 downward, so that the reset stop column 4 is away from the rotation path of the safety door 3, and the plug can drive the safety door 3 to rotate. After rotating to a certain angle, it is aligned with the insertion hole on the base 5, so that the plug can be inserted into the insertion hole and contact with the metal contact piece 6 on the base 5. When the plug is unplugged, the safety door 3 is reset, and the reset stop post 4 is also reset after the safety door 3 is reset, so that the safety door 3 is locked. At the same time, the area of the reset stop post 4 can be made very small, for example, the cross-sectional area of the reset stop post 4 is one-fifth of the area of the socket 31. In this way, even if babies or children use other tools such as scissors, chopsticks, etc. to play, they still cannot accurately insert the reset stop post 4, so that the safety door 3 cannot be rotated, making it have a self-locking function. Even if they can insert the reset stop post 4 with these tools, it is difficult to rotate the safety door 3, so that the risk of electric shock is minimized while not hindering the convenience of electricity use, thereby obtaining comprehensive safety protection.

[0035] That is, the use process of the self-locking electrical socket with a safety door provided by the present invention is staggered insertion, automatic unlocking, rotation alignment and continued insertion to utilize electricity. When unplugged, the safety door 3 and the reset stop column 4 can be automatically reset to achieve the self-locking function.

[0036] In other implementations, plugs of special shapes can also be used, and some electrical appliances that can be taken away after use can be equipped. Taking an electric kettle as an example, the electric kettle uses a special plug, and the shape of the socket 31 corresponds to the shape of the special plug. When the electric kettle is used up, it is usually taken away from the socket, so that any other ordinary plug cannot be inserted into the plug well, that is, there is no good tool to unlock the socket. Even if some plugs, chopsticks, etc. can be inserted and the reset stop column 4 is pressed, they cannot rotate the safety door 3 well. If the shape does not correspond, when the safety door 3 is rotated, its end will slide away from the reset stop column 4, so that the reset stop column 4 automatically resets and blocks the safety door 3 so that it cannot rotate, thereby minimizing the risk of electric shock without hindering the convenience of electricity use, thereby obtaining comprehensive safety protection.

[0037] In this embodiment, there are two safety doors 3, which include a first safety door and a second safety door. The first safety door has two sockets 31, and the second safety door has three sockets 31. In other embodiments, there may be one safety door 3 with two sockets 31 or three sockets 31, or other numbers of sockets 31. There may also be multiple safety doors 3, such as a power strip, which requires multiple safety doors 3. All of these should fall within the scope of protection of the present invention.

[0038] Furthermore, there are at least two sockets 31, and the two sockets 31 include at least a first socket and a second socket. There are two reset stop posts 4, and the two reset stop posts 4 include a first stop post and a second stop post. The first stop post is located on the upper side of the first socket, and the second stop post is located on the lower side of the second socket. In this way, when the reset stop post 4 is pressed using other tools, the first stop post and the second stop post cannot be pressed at the same time. Even if the first stop post and the second stop post can be pressed at the same time, it is easy to slide off the first stop post and the second stop post when the safety door 3 is rotated, so that the reset stop post 4 automatically resets and blocks the safety door 3 so that it cannot rotate, thereby minimizing the risk of electric shock without hindering the convenience of electricity use, thereby obtaining comprehensive safety protection.

[0039] Furthermore, the reset stop column 4 includes a stop column and a spring sleeved on the stop column. The stop column plays a blocking role. The spring allows the stop column to be pressed downward without blocking the safety door 3, and allows the stop column to be reset after the safety door 3 is reset.

[0040] Example 2, please refer to Figure 2 、 Figure 6 and Figure 7As a further optimization scheme of Example 1, in this embodiment, a middle shell 7 is provided between the upper shell 1 and the lower shell 2, and a placement groove 71 is provided on the middle shell 7. A torsion spring 8 is provided in the placement groove 71. A torsion column 32 is provided on the lower surface of the safety door 3, and the torsion spring 8 is sleeved on the torsion column 32, so that the safety door 3 can be reset by the action of the torsion spring 8 when rotating.

[0041] Furthermore, a blocking post hole 72 is provided on the middle shell 7 , and the blocking post hole 72 is sleeved on the reset blocking post 4 , and the blocking post hole 72 can play a positioning role.

[0042] Furthermore, a boss 33 is provided on the lower surface of the safety door 3 located at the non-rotation center, and a limit groove 73 corresponding to the boss 33 is provided on the middle shell 7. The limit groove 73 can limit the rotation distance of the safety door 3, so that the safety door 3 can be designed to be aligned with the insertion hole on the base 5 when it is rotated to the end, making it more convenient to insert the plug and align it with the insertion hole, thereby avoiding affecting the convenience of electricity use.

[0043] Furthermore, the cross-sectional shape of the safety door 3 is circular. Of course, in other embodiments, other shapes such as ellipse, triangle, quadrilateral, etc. can also be adopted. The circular safety door 3 can rotate better and prevent dust and foreign matter from entering the interior of the socket.
