Description

Adapter socket

[0001] This application claims priority to Chinese Patent Application No. 202411997240.3, filed on December 31, 2024, entitled "Converter Socket", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electrical equipment technology, and more specifically, to a converter socket. Background Technology

[0003] Due to differences in sockets between countries, and the different standards for chargers or plugs in each country, adapter sockets that integrate plugs from major countries around the world have emerged to meet the needs of global business, travel abroad, and study abroad.

[0004] However, in related technologies, when one set of plugs is used in a converter socket, the other sets of plugs can extend, which can cause the metal prongs of the other sets of plugs to extend accidentally, making it easy for users to touch the metal prongs and cause electric shock accidents, thus increasing the safety risks for users. Summary of the Invention

[0005] This application provides a converter socket designed to interlock the rotating plug and the second sliding plug through the cooperation of a locking member and a limiting component, thereby facilitating the use of the converter socket by the user.

[0006] This application provides a converter socket, which includes a housing, a rotating plug, a locking member, a first sliding plug, and a limiting assembly. The rotating plug is mounted on the housing and rotatably connected to the housing via a rotating part. The first sliding plug is mounted on the housing and can slide vertically relative to the housing. The limiting assembly is mounted on the housing and can move horizontally relative to the housing, and the limiting assembly has a first limiting part and a second limiting part. The locking member is disposed inside the housing and is convexly connected to the rotating part. When the first sliding plug is in a retracted state and the rotating plug is switched from a retracted state to a usable state, the rotating plug drives the first limiting part to produce a linear displacement, causing the second limiting part to engage with the first sliding plug. The rotating part also drives the locking member to move, causing the locking member to engage with the limiting assembly. When the rotating plug is in a retracted state and the first sliding plug is switched from a retracted state to a usable state, the first sliding plug drives the second limiting part to move linearly, causing the first limiting part to engage with the rotating plug.

[0007] Based on the adapter socket of this application, when the rotary plug is in use, the locking member locks the first sliding plug in the retracted state through the limiting component. When the first sliding plug is in use, the limiting component locks the rotary plug in the retracted state, thereby realizing the interlocking of the rotary plug and the first sliding plug. This can prevent the other from accidentally extending and causing an electric shock accident when one of the rotary plug and the first sliding plug is in use, thereby improving the safety of the adapter socket.

[0023] Please refer to Figures 1 and 2 together. This embodiment of the application provides a conversion socket 1, which includes a housing 11, a rotating plug 12, a locking member 13, a first sliding plug 14, and a limiting component 15. The housing 11 can be made of various materials, including polycarbonate, ABS, and other insulating materials; no specific limitation is made here. The housing 11 can also have various shapes, including square, cylindrical, and other shapes; no specific limitation is made here.

[0024] The rotating plug 12 is mounted on the housing 11 and is rotatably connected to the housing 11 via the rotating part 121. It should be noted that when the rotating plug 12 is in use, it extends out of the housing 11 to connect to an external socket. When the rotating plug 12 is in the retracted state, it is retracted into the outer surface of the housing 11.

[0025] Please refer to Figures 3 and 4. The locking element 13 is disposed within the housing 11 and is connected to the rotary plug 12. The locking element 13 can be made of various materials, including metal and plastic; no specific limitation is made here. Preferably, the locking element 13 is made of plastic to prevent the plug pins from contacting the locking element 13 and causing a short circuit. The locking element 13 can have various shapes, including square, cylindrical, or other shapes; no specific limitation is made here. The locking element 13 can be disposed within the housing 11 in various ways, such as sliding or rotating within it; no specific limitation is made here. The locking element 13 can be connected to the rotary plug 12 in various ways, such as through abutment or via a gear and rack mechanism; no specific limitation is made here.

[0026] Please refer to Figures 3 and 4. The first sliding plug 14 is installed on the housing 11 and can slide vertically relative to the housing 11. When the first sliding plug 14 is in use, it extends out of the housing 11 to connect to an external socket. When the first sliding plug 14 is in the retracted state, it can be stored inside the housing 11 or on the outer surface of the housing 11; no specific limitation is made here.

[0027] Please refer to Figures 3 and 4. The limiting component 15 is installed on the housing 11 and can move horizontally relative to the housing 11. The limiting component 15 has a first limiting part 151 and a second limiting part 152. The first limiting part 151 and the second limiting part 152 are connected in a transmission manner. The first limiting part 151 is connected in a transmission manner to the rotating plug 12 by abutment. The second limiting part 152 is connected in a transmission manner to the first sliding plug 14 by abutment. It should be noted that when the first sliding plug 14 is in the storage state and the rotating plug 12 is rotated from the storage state to the use state, the rotating plug 12 can drive the first limiting part 151 to move, thereby moving the second limiting part 152 to block the first sliding plug 14. The rotating plug 12 can also drive the locking member 13 to move to lock the limiting component 15, thereby locking the first sliding plug 14 in the storage state. When the rotating plug 12 is in the storage state and the first sliding plug 14 slides from the storage state to the use state, the first sliding plug 14 can drive the second limiting part 152 to move so that the first limiting part 151 slides to lock the rotating plug 12 in the storage state.

[0028] The first limiting part 151 can slide in a direction parallel to the rotation axis of the rotating plug 12, or it can slide in a direction at an angle to the rotation axis of the rotating plug 12; no specific limitation is made here. Preferably, the first limiting part 151 slides in a direction parallel to the rotation axis of the rotating plug 12, so that the space of the housing 11 on the rotation axis of the rotating plug 12 can be fully utilized.

[0029] The movement direction of the second limiting part 152 can be the same as that of the first limiting part 151, or it can be set at an angle to the movement direction of the first limiting part 151. No specific limitation is made here. Preferably, the first limiting part 151 slides along a direction parallel to the rotation axis of the rotating plug 12, and the movement direction of the second limiting part 152 is perpendicular to the movement direction of the first limiting part 151. This reduces the space occupied by the first limiting part 151 in the rotation axis of the rotating plug 12, while fully utilizing the space of the housing 11 perpendicular to the rotation axis of the rotating plug 12, thereby reducing the length of the housing 11 in the axial direction of the rotating plug 12 and consequently reducing the volume of the adapter socket 1.

[0030] There are many ways in which the locking member 13 locks the limiting component 15. The locking member 13 can lock the limiting component 15 by snapping or by plugging it in. No specific limitation is made here.

[0031] There are many ways in which the locking member 13 can release its restriction on the limiting component 15. For example, when the rotating plug 12 is rotated from the use state to the storage state, the locking member 13 can release its restriction on the limiting component 15 under the drive of the rotating plug 12. Or, when the rotating plug 12 is rotated from the use state to the storage state, the rotating plug 12 releases its restriction on the locking member 13. At this time, when the limiting component 15 slides to lock the rotating plug 12, the limiting component 15 can drive the locking member 13 to slide. No specific limitation is made here.

[0032] Referring to Figure 4, when the rotating plug 12 is in the retracted state and the first sliding plug 14 rotates from the retracted state to the use state, the first sliding plug 14 can drive the second limiting part 152 to move linearly, so that the first limiting part 151 engages with the rotating plug 12. It should be noted that when the first sliding plug 14 is in the use state, it limits the second limiting part 152, preventing the first limiting part 151 from sliding, thus keeping the first limiting part 151 in the position that locks the rotating plug 12 in the retracted state. When the first sliding plug 14 is in the retracted state, it does not limit the second limiting part 152, allowing the rotating plug 12 to drive the first limiting part 151 to slide and switch to the use state.

[0033] There are many ways in which the first limiting part 151 locks the rotating plug 12. The first limiting part 151 can lock the rotating plug 12 by snapping or by plugging it in. No specific limitation is made here.

[0034] Referring to Figure 3, when the first sliding plug 14 is in the retracted state and the rotating plug 12 is rotated from the retracted state to the use state, the rotating plug 12 can drive the first limiting part 151 to produce a linear displacement, causing the second limiting part 152 to engage with the first sliding plug 14. The rotating part 121 also drives the locking member 13 to move, so that the locking member 13 engages with the limiting assembly 15. It should be noted that when the rotating plug 12 is in the use state, the rotating part 121 limits the locking member 13, keeping it in the position that locks the first limiting part 151, thus preventing the second limiting part 152 from sliding and keeping it in the position that locks the first sliding plug 14 in the retracted state. When the rotating plug 12 is in the retracted state, the rotating part 121 does not limit the locking member 13, so the locking member 13 does not limit the first limiting part 151, allowing the first sliding plug 14 to drive the second limiting part 152 to slide and switch to the use state.

[0035] There are many ways in which the second limiting part 152 locks the first sliding plug 14. The second limiting part 152 may extend partially into the sliding path of the first limiting component 15 to prevent the first limiting component 15 from switching to the use state. The second limiting part 152 may also be plugged into the first limiting component 15 to prevent the first limiting component 15 from switching to the use state. No specific limitation is made here.

[0036] There are many ways to drive the locking member 13 to move. For example, when the rotating plug 12 is rotated from the use state to the storage state, the rotating part 121 drives the locking member 13 to move to release the limit component 15; or, when the first sliding plug 14 slides from the storage state to the use state, the first sliding plug 14 drives the second limit part 152 to slide to drive the first limit part 151, and the locking member 13 is driven to move through the first limit part 151. These are just a few examples.

[0037] Based on the adapter socket 1 of this application, when the rotary plug 12 is in use, the locking member 13 locks the first sliding plug 14 in a retracted state through the limiting component 15. When the first sliding plug 14 is in use, the limiting component 15 locks the rotary plug 12 in a retracted state, thereby realizing the interlocking of the rotary plug 12 and the first sliding plug 14. This can prevent the other from accidentally extending and causing an electric shock accident when one of the rotary plug 12 and the first sliding plug 14 is in use, thereby improving the safety of the adapter socket 1.

[0038] Please refer to Figures 3 and 4 together. In some embodiments of this application, the rotating part 121 is provided with a crank drive part 122. The crank drive part 122 is located on the side of the rotating plug 12 near the locking member 13 and is located on the rotating shaft of the rotating plug 12. When the first sliding plug 14 is in the retracted state and the rotating plug 12 rotates from the retracted state to the used state, the crank drive part 122 drives the locking member 13 to slide to lock the first limiting part 151, so as to lock the first sliding plug 14 in the retracted state through the second limiting part 151. This arrangement makes full use of the space on the rotating shaft of the rotating plug 12, and at the same time simplifies the transmission structure between the rotating plug 12 and the locking member 13, thereby simplifying the structure of the adapter socket 1.

[0039] It should be noted that, referring to Figure 3, the crank drive unit 122 has a drive section 1221 and a clearance section 1222. The distance between the drive section 1221 and the pivot of the rotary plug 12 is greater than the distance between the clearance section 1222 and the pivot of the rotary plug 12. When the first sliding plug 14 is in the retracted state and the rotary plug 12 is rotated from the retracted state to the use state, the drive section 1221 abuts against the locking member 13 to drive the locking member 13 to move to lock the limiting component 15. When the rotary plug 12 is in the retracted state, the clearance section 1222 faces the locking member 13 to provide sufficient movement space for the locking member 13 when the first sliding plug 14 switches from the retracted state to the use state.

[0040] Furthermore, referring to Figures 2 and 3, the rotary plug 12 also includes a mating part 123, which is disposed on the rotary plug 12 and located on the same surface as the crank drive part 122. When the rotary plug 12 is in the retracted state and the first sliding plug 14 is in the use state, the limiting component 15 engages with the mating part 123. This arrangement, with the crank drive part 122 and the mating part 123 on the same surface of the rotary plug 12, ensures that the limiting component 15 and the locking member 13 are both located on the same side of the rotary plug 12, thus simplifying the structure of the adapter socket 1. Simultaneously, the engagement of the mating part 123 with the limiting component 15 allows the limiting component 15 to stably limit the rotation of the rotary plug 12.

[0041] There are many ways in which the mating part 123 and the limiting component 15 can be inserted and engaged. For example, the mating part 123 is a protrusion, and the limiting component 15 is provided with a groove for insertion and engagement with the protrusion; or the mating part 123 is a groove, and the limiting component 15 extends into the groove to insert and engage with the groove. These are not all listed here.

[0042] Typically, the surface of the housing 11 is recessed to accommodate the rotating plug 12 in its retracted state. To protect the limiting component 15, the limiting component 15 is housed in the mounting cavity within the housing 11. In this case, the groove wall of the accommodating groove is provided with a through hole for the limiting component 15 to extend out. Considering that the mating part 123 is a protrusion, in order to avoid interference between the mating part 123 and the groove wall of the accommodating groove when the rotating plug 12 rotates, a clearance channel needs to be formed between the groove wall of the accommodating groove with the through hole and the groove wall of the rotating plug 12 with the mating part 123. This will cause the limiting component 15 to be exposed from the clearance channel when it is inserted into the mating part 123. Therefore, preferably, the mating part 123 is a groove, and the limiting component 15 extends into the groove to engage with it. This ensures that the groove wall with the through hole in the receiving groove and the groove wall with the mating part 123 in the rotating plug 12 are closely fitted, thereby reducing the exposed area of ​​the limiting component 15 when it engages with the mating part 123, thus better protecting the limiting component 15 and optimizing the appearance of the rotating plug 12. To facilitate the movement of the first limiting part 151 driven by the rotating plug 12, the groove is provided with a driving slope 124, and the end of the first limiting part 151 extending into the groove is provided with an abutting slope 1513. When the rotating plug 12 switches from the storage state to the use state, the driving slope 124 engages with the abutting slope 1513, causing the first limiting part 151 to exit the groove.

[0043] In some embodiments of this application, please refer to Figures 2, 3, and 5. The first limiting portion 151 has a locking groove 1511 recessed at one end near the locking member 13. When the first sliding plug 14 is in the retracted state and the rotating plug 12 is in the usage state, the locking member 13 engages with the locking groove 1511 to lock the first sliding plug 14 in the retracted state. This configuration, with the locking groove 1511 at one end of the first limiting portion 151 near the locking member 13, shortens the travel distance of the locking member 13. Simultaneously, the engagement of the locking member 13 with the locking groove 1511 allows for more stable limiting of the locking member 13. It is understood that when the first sliding plug 14 is in the usage state, the locking groove 1511 and the locking member 13 are misaligned, preventing the locking member 13 from extending into the locking groove 1511, thus preventing the locking member 13 from limiting the first limiting portion 151.

[0044] There are many ways in which the locking member 13 can exit the locking groove 1511. The locking member 13 can exit the locking groove 1511 under the drive of the rotating plug 12, or it can exit the locking groove 1511 under the drive of the first limiting part 151. No specific limitation is made here. The position of the locking groove 1511 is related to the movement of the locking member 13. For example, when the locking member 13 can slide relative to the housing 11, the locking groove 1511 is provided on the surface of the first limiting part 151 facing the locking member 13; or, when the locking member 13 can rotate relative to the housing 11, the end of the locking member 13 near the first limiting part 151 can move up and down, and the locking groove 1511 is provided on the surface of the rotating plug 12 in the up and down direction. These are not listed one by one here. It should be noted that when the locking member 13 can rotate relative to the housing 11, the rotating shaft of the rotating plug 12 and the first limiting part 151 can be located on the same side of the rotating shaft of the locking member 13, or the rotating shaft of the rotating plug 12 and the first limiting part 151 can be located on opposite sides of the rotating shaft of the locking member 13, without any specific limitation.

[0045] Further, referring to Figure 5, the locking member 13 has a guide slope 131 at one end near the first limiting part 151, and the locking groove 1511 has a mating slope 1512 on the groove surface facing the guide slope 131. When the rotating plug 12 is in the retracted state and the first sliding plug 14 slides from the retracted state to the use state, the first sliding plug 14 can drive the second limiting part 152 to slide, thereby causing the first limiting part 151 to slide. The first limiting part 151, through the mating slope 1512 and the guide slope 131, drives the locking member 13 to exit the locking groove 1511. With this configuration, when the rotating plug 12 is in the retracted state and the first sliding plug 14 slides from the retracted state to the use state, the first limiting part 151 can drive the locking member 13 to exit the locking groove 1511, thus eliminating the need for a structure where the rotating plug 12 drives the locking member 13 to exit the locking groove 1511, thereby simplifying the structure of the adapter socket 1.

[0046] Please refer to Figures 2 and 5 together. In some embodiments of this application, one of the first limiting part 151 and the second limiting part 152 is provided with a driving part 153, and the other of the first limiting part 151 and the second limiting part 152 is provided with an inclined slide groove 154. The driving part 153 extends into the inclined slide groove 154, so that the first limiting part 151 and the second limiting part 152 are connected by the driving part 153 and the inclined slide groove 154. With this configuration, the first limiting part 151 and the second limiting part 152 can be connected by extending the driving part 153 into the inclined slide groove 154, thereby simplifying the transmission structure between the first limiting part 151 and the second limiting part 152. At the same time, the cooperation between the inclined slide groove 154 and the driving part 153 allows the first limiting part 151 and the second limiting part 152 to slide in two intersecting directions.

[0047] It is understood that the extension direction of the inclined slide 154 includes the movement direction of the first limiting part 151 and the movement direction of the second limiting part 152. If the first limiting part 151 is provided with a driving part 153, then the second limiting part 152 is provided with the inclined slide 154; if the first limiting part 151 is provided with the inclined slide 154, then the second limiting part 152 is provided with the driving part 153.

[0048] Please refer to Figures 2 and 6. In some embodiments of this application, the adapter socket 1 further includes a second sliding plug 16 and a locking assembly 20. The second sliding plug 16 is mounted on the housing 11 and can slide vertically relative to the housing 11. The locking assembly 20 is kinetically connected to the rotating plug 12, the first sliding plug 14 and the third sliding plug 16.

[0049] When one of the rotating plug 12, the first sliding plug 14, and the second sliding plug 16 is in use, the other two are in a retracted state and are locked in this retracted state by the limiting component 15. This configuration improves the practicality of the adapter socket 1 by including the second sliding plug 16. Simultaneously, it achieves interlocking of the rotating plug 12, the first sliding plug 14, and the second sliding plug 16, thereby preventing the other two from accidentally extending and causing electric shock when one is in use, thus improving the safety of the adapter socket 1.

[0050] It should be noted that the first sliding plug 16 can be located on the side of the rotating plug 12 closer to the first sliding plug 14, and the second sliding plug 16 can also be located on the side of the rotating plug 12 away from the first sliding plug 14. No specific limitation is made here.

[0051] There are many ways to achieve interlocking between the limiting component 15 and the locking component 20 to achieve interlocking of the rotating plug 12, the first sliding plug 14 and the second sliding plug 16.

[0052] For example, the locking assembly 20 also includes a first locking block and a second locking block. The first locking block is convexly connected to the rotating plug 12 and the second sliding plug 16, and the second locking block is convexly connected to the first sliding plug 14 and the second sliding plug 16. When the rotating plug 12 switches from the storage state to the use state, the rotating plug 12 drives the first locking block to slide to lock the second sliding plug 16 in the storage state. When the first sliding plug 14 switches from the storage state to the use state, the first sliding plug 14 drives the second locking block to slide to lock the second sliding plug 16 in the storage state. When the second sliding plug 16 switches from the storage state to the use state, the second sliding plug 16 drives the first locking block to slide to lock the rotating plug 12 in the storage state, and the second sliding plug 16 drives the second locking block to slide to lock the first sliding plug 14 in the storage state.

[0053] For example, the limiting component 15 also includes a first locking block, which is convexly connected to the second sliding plug 16. When the rotating plug 12 switches from the storage state to the use state, the rotating plug 12 drives the first limiting part 151 to slide to lock the second sliding plug 16 in the storage state. When the first sliding plug 14 switches from the storage state to the use state, the first sliding plug 14 drives the first locking block to slide to lock the second sliding plug 16 in the storage state. When the second sliding plug 16 switches from the storage state to the use state, the second sliding plug 16 drives the first limiting part 151 to slide to lock the rotating plug 12 in the storage state, and the second sliding plug 16 drives the first locking block to slide to lock the first sliding plug 14 in the storage state. These are just a few examples.

[0054] Preferably, the locking assembly 20 includes a locking part 21, a first limiting part 151 disposed inside the housing 11 and pulsatorically connected to the rotating plug 12; a second limiting part 152 mounted on the housing 11 and slidable relative to the housing 11, and pulsatorically connected to the first limiting part 151 and the first sliding plug 14; the locking part 21 is mounted on the housing 11 and pulsatorically connected to the first sliding plug 14, the second sliding plug 16 and the second limiting part 152.

[0055] Specifically, when the rotating plug 12 is in use, the second limiting part 151 locks the first sliding plug 14 in a stored state, the second limiting part 152 abuts against the locking part 21, and the locking part 21 locks the second sliding plug 16 in a stored state; when the first sliding plug 14 is in use, the first limiting part 151 locks the rotating plug 12 in a stored state, and the locking part 21 locks the second sliding plug 16 in a stored state; when the second sliding plug 16 is in use, the locking part 21 abuts against the second limiting part 152, the second limiting part 152 locks the second sliding plug 16 in a stored state, and the first limiting part 151 locks the rotating plug 12 in a stored state.

[0056] This configuration enables interlocking of the rotary plug 12, the first sliding plug 14, and the second sliding plug 16, thereby preventing the other two from accidentally extending and causing electric shock when one of them is in use, thus improving the safety of the adapter socket 1. Simultaneously, the second sliding plug 16 can be driven to slide to abut against the second limiting part 152 via the driving locking part 21, thereby moving the second limiting part 152. This simplifies the transmission structure for locking the rotary plug 12 by the second sliding plug 16, and further simplifies the structure of the adapter socket 1.

[0057] In some embodiments of this application, the first sliding plug 14 is located between the rotating plug 12 and the second sliding plug 16, and the first sliding plug 14 is located between the second limiting part 152 and the locking part 21. The second limiting part 152 and the locking part 21 are both located on the same side of the rotation axis of the rotating plug 12, and the locking part 21 and the second limiting part 152 can both slide along the first sliding direction and the second sliding direction, which are opposite to each other.

[0058] Please refer to Figure 3. When the rotating plug 12 is rotated from the storage state to the use state, the rotating plug 12 can drive the first limiting part 151 to slide, causing the second limiting part 152 to slide along the second sliding direction. The second limiting part 152 abuts against the locking part 21, causing the second limiting part 152 to drive the locking part 21 to slide along the second sliding direction to block the second sliding plug 16. The rotating plug 12 can also drive the locking member 13 to lock the first limiting part 151, so that the second limiting part 152 and the locking part 21 cannot move. Thus, the second limiting part 152 and the locking part 21 respectively lock the first sliding plug 14 and the second sliding plug 16 in the storage state.

[0059] Please refer to Figure 4. When the first sliding plug 14 slides from the storage state to the use state, the first sliding plug 14 can drive the locking part 21 to slide along the second sliding direction to lock the second sliding plug 16 in the storage state, and the first limiting part can drive the second limiting part 152 to slide along the first sliding direction to drive the first limiting part 151 to slide to lock the rotating plug 12 in the storage state.

[0060] Please refer to Figure 6. When the second sliding plug 16 slides from the storage state to the use state, the second sliding plug 16 can drive the locking part 21 to slide along the first sliding direction to lock the first sliding plug 14 in the storage state. The locking part 21 abuts against the second limiting part 152, causing the second limiting part 152 to slide along the first sliding direction. The second limiting part 152 causes the first limiting part 151 to slide to lock the rotating plug 12 in the storage state.

[0061] For ease of understanding, the two pins of the first sliding plug 14 are arranged along the first width direction, and the two pins of the second sliding plug 16 are arranged along the second width direction. Preferably, the first width direction and the second width direction are parallel, which can avoid interference between the first sliding plug 14 and the second sliding plug 16, and also make the appearance of the adapter 1 more aesthetically pleasing. The first width direction and the second width direction can both be perpendicular to the rotation axis of the rotating plug 12, or they can both be parallel to the rotation axis of the rotating plug 12; no specific limitation is made here.

[0062] Preferably, referring to Figure 1, the first limiting part 151 is located between the rotating plug 12 and the locking part 21, and both the first width direction and the second width direction are parallel to the rotation axis of the rotating plug 12. In this case, the rotating plug 12, the first sliding plug 14 and the second sliding plug 16 are arranged in sequence along directions perpendicular to the first width direction and the second width direction, which makes the appearance of the rotating socket more aesthetically pleasing. At the same time, the first limiting part 151, the second limiting part 152 and the locking part 21 are all located on the same side of the first sliding plug 14 in the first width direction, thereby reducing the space occupied by the limiting component 15, facilitating the design of the limiting component 15, and thus reducing the volume of the adapter socket 1 and simplifying the structure of the adapter socket 1.

[0063] Please refer to Figure 2. The first sliding plug 14 includes a first sliding plug body 141 and a first driving member 142. The first sliding plug body 141 is mounted on the housing 11 and can slide relative to the housing 11. The first driving member 142 is convexly connected to the first sliding plug body 141 and extends partially out of the housing 11. The second sliding plug 16 includes a second sliding plug body 161 and a second driving member 162. The second sliding plug body 161 is mounted on the housing 11 and can slide relative to the housing 11. The second driving member 162 is convexly connected to the second sliding plug body 161 and extends partially out of the housing 11.

[0064] Referring to Figure 3, when the rotating plug 12 is in use, the second limiting part 152 blocks the first driving member 142, and the locking part 21 blocks the second driving member 162, so as to lock the first sliding plug 14 and the second sliding plug 16 in the storage state.

[0065] Please refer to Figure 4. When the first sliding plug 14 is in use, the locking part 21 blocks the second driving member 162 to lock the second sliding plug 16 in the storage state.

[0066] Please refer to Figure 6. When the second sliding plug 16 is in use, the locking part 21 blocks the first driving member 142 to lock the first sliding plug 14 in the storage state.

[0067] With this configuration, the user can drive the first sliding plug body 141 and the second sliding plug body 161 to slide using the portions of the first driving member 142 and the second driving member 162 extending out of the housing 11, respectively. This facilitates the user switching between the first sliding plug 14 and the second sliding plug 16 in the use state and the storage state, thereby making it easier for the user to use the adapter socket 1. At the same time, the second limiting part 152 and the locking part 21 can lock the first sliding plug 144 in the storage state by blocking the first driving member 142, and the locking part 21 can lock the second sliding plug 16 in the storage state by blocking the second driving member 162, thereby simplifying the structure of the limiting component 15.

[0068] In some embodiments of this application, please refer to FIG3. When the adapter plug is in use, the locking member 13 is limited by the rotating plug 12, and the locking member 13 limits the first limiting part 151. Since the first limiting part 151 is connected to the second limiting part 152 and the first limiting part 151 is limited, the second limiting part 152 cannot move. The second limiting part 152 blocks the first driving member 142 and limits the locking part 21. The locking part 21 blocks the second driving member 162.

[0069] Please refer to Figure 4. When the first sliding plug 14 is in use, the first driving member 142 limits the second limiting part 152. Since the first limiting part 151 and the second limiting part 152 are connected by transmission and the second limiting part 152 is limited, the first limiting part 151 cannot move. The first limiting part 151 limits the rotating plug 12, and the first driving member 142 limits the locking part 21. The locking part 21 blocks the second driving member 162.

[0070] Please refer to Figure 6. When the second sliding plug 16 is in use, the second driving member 162 limits the locking part 21 and limits the second limiting part 152 through the locking part 21. The locking part 21 blocks the first driving member 142. Since the first limiting part 151 and the second limiting part 152 are connected in transmission and the second limiting part 152 is limited, the first limiting part 151 cannot move. The first limiting part 151 limits the rotating plug 12.

[0071] Further, referring to Figures 7 and 8, the first driving member 142 is mounted on the first sliding plug body 141 and can slide relative to the first sliding plug body 141 to switch between an unlocked position and a locked position. When the first sliding plug 14 is in the use state and the first driving member 142 is in the locked position, the first driving member 142 cooperates with the second limiting part 152 and / or the locking part 21 to lock the first sliding plug body 141 in the use state. When the first driving member 142 is in the unlocked position, the first sliding plug 12 can switch between a storage state and a use state. This configuration can prevent the adapter socket 1 from being shaken, causing the first sliding plug to switch from the use state to the storage state, thus facilitating the user's use of the adapter socket 1.

[0072] It should be noted that when the first sliding plug 14 is in use, it needs to limit the second limiting part 152 and the locking part 21. The first sliding plug 14 limits the second limiting part 152 and the locking part 21, and there are many ways in which the first sliding plug 14 cooperates with the second limiting part 152 and / or the locking part 21 to lock the first sliding plug body 141 in the use state. For ease of understanding, we define the first sliding plug 14 sliding upward to switch to the use state and the first sliding plug 14 sliding downward to switch to the storage state.

[0073] For example, the first driving member 142 is provided with a snap-fit ​​portion and an overlapping portion located above the snap-fit ​​portion. When the first sliding plug 14 is in use and the first driving member 142 is in the locked position, the snap-fit ​​portion is located between the second limiting portion 152 and the locking portion 21 to limit the downward sliding direction of the first driving member 142, thereby locking the first sliding plug body 141 in the use state.

[0074] For example, the first driving member 142 is provided with a locking part 1421, and the second limiting part 152 and / or the locking part 21 is provided with a limiting groove 17. The locking part 1421 cooperates with the limiting groove 17 to limit the second limiting part 152 and the locking part 21, and at the same time limit the downward sliding direction of the first driving member 142, thereby locking the first sliding plug body 141 in the use state. These are just a few examples.

[0075] Preferably, referring to Figures 7 and 8, the first driving member 142 is provided with a locking part 1421, and the second limiting part 152 and / or the locking part 21 is provided with a limiting groove 17. When the first sliding plug 14 is in use and the first driving member 142 is in the locked position, the locking part 1421 is engaged with the limiting groove 17. When the first driving member 142 switches from the locked position to the unlocked position, the locking part 1421 exits the limiting groove 17 to release the limitation on the first driving member 142, so that the first sliding plug 14 can be switched to the storage state. In this way, the locking part 1421 and the limiting groove 17 can be engaged to limit the second limiting part 152 and the locking part 21, as well as the first driving member 142, thereby simplifying the structure of the adapter plug 1.

[0076] When the first sliding plug 14 is in use and the first driving member 142 is in the locked position, the locking part 1421 will engage with the limiting groove 17. When it is necessary to slide the first sliding plug 14 to the storage state, the first driving member 142 needs to be switched to the unlocked position first, so that the locking part 1421 is disengaged from the limiting groove 17. Only then can the first sliding plug body 141 be driven to slide by the first driving member 142, thereby preventing the adapter socket 1 from being shaken and causing the first sliding plug to switch from the use state to the storage state, thus making it easier for the user to use the adapter socket 1.

[0077] In some embodiments of this application, the first sliding plug 14 further includes an elastic member 143. One end of the elastic member 143 abuts against the first sliding plug body 141, and the other end of the elastic member 143 abuts against the first driving member 142, so that the first driving member 142 has a tendency to switch from the unlocked position to the locked position. With this configuration, the elastic member 143 can make the locking part 1421 stably stay in the locked position, so that the first sliding plug 14 can be stably in the use state, thereby facilitating the user to use the adapter socket 1.

[0078] It should be noted that the first driving member 142 is sequentially provided with a driving part, a connecting part, a locking part 1421, and a transmission part. The driving part extends out of the housing, and the transmission part is connected to the first sliding plug body 141. Since the locking part 1421 is engaged with the limiting groove 17, the width of part of the locking part 1421 is greater than the maximum distance between the second limiting part 152 and the locking part 21. Therefore, when the first sliding plug 14 is in the storage state and the first driving member 142 is in the locked position, the locking part 1421 cannot pass between the second limiting part 152 and the locking part 21, so the first sliding plug 14 cannot be switched to the use state. Only when the first driving member 142 is switched to the unlocked position can the first sliding plug 14 be driven to switch from the storage state to the use state. This can prevent the adapter socket 1 from being shaken and causing the first sliding plug 14 to switch to the use state, which makes it easier for the user to store the adapter socket 1. It is understandable that when the first sliding plug 14 is switched to the use state, the first driving member 142 drives the second limiting part and the locking part to slide through the connecting part.

[0079] Please refer to Figures 2 and 4 together. In some embodiments of this application, the second limiting part 152 is provided with a first ramp 1521 at one end near the first sliding plug 14. When the first sliding plug 14 slides to the use state, the first sliding plug 14 and the first ramp 1521 cooperate to drive the second limiting part 152 to slide along the first sliding direction. With this configuration, it is only necessary to provide the first ramp 1521 on the second limiting part 152 to associate the movement of the first driving member 142 extending out of the housing 11 with the movement of the second limiting part 152 in the first sliding direction, thereby simplifying the overall structure of the conversion socket 1.

[0080] Please refer to Figures 2 and 4 together. In some embodiments of this application, a second ramp 211 is provided at one end of the locking part 21 near the first sliding plug 14. When the first sliding plug 14 is slid to the use state, the first sliding plug 14 and the second ramp 211 cooperate to drive the locking part 21 to slide along the second sliding direction. With this configuration, it is only necessary to provide the second ramp 211 on the locking part 21 to associate the movement of the second driving member 162 extending out of the housing 11 with the movement of the locking part 21 in the second sliding direction, thereby simplifying the overall structure of the conversion socket 1.

[0081] Please refer to Figures 2 and 6 together. In some embodiments of this application, a third ramp 212 is provided at the end of the locking part 21 near the second sliding plug 16. When the second sliding plug 16 slides to the use state, the second sliding plug 16 and the third ramp 212 cooperate to drive the locking part 21 to slide along the first sliding direction. With this configuration, only the third ramp 212 needs to be provided on the locking part 21 to associate the movement of the second driving member 162 extending out of the housing 11 with the movement of the locking part 21 in the first sliding direction, thereby simplifying the overall structure of the conversion socket 1.

[0082] Considering the longer prongs of the European standard plug, the sliding of the European standard plug relative to the housing 11 results in a longer distance between the surface of the housing 11 facing away from the external socket and the external socket when the European standard plug is connected. This causes the center of gravity of the adapter plug to be farther from the external socket, making the adapter plug prone to falling. Therefore, please refer to Figures 1 and 3, rotating the plug 12 to the European standard plug configuration. This design shortens the distance between the surface of the housing 11 facing away from the external socket and the external socket when the European standard plug is connected, thus bringing the center of gravity of the adapter plug closer to the external socket, and allowing for a more stable connection between the adapter plug and the external socket.

[0083] Referring to Figure 2, in some embodiments of this application, the adapter socket 1 further includes an electrical connector 18 and a protection module 19. The electrical connector 18 is mounted on the housing 11; the protection module 19 is mounted on the housing 11. When the rotary plug 12 is in use, the rotary plug 12 is electrically connected to the electrical connector 18 through the protection module 19. When the rotary plug 12 is in a retracted state, the rotary plug 12 is disconnected from the electrical connector 18 through the protection module 19. When the first sliding plug 14 is in use, the second sliding plug 16 is electrically connected to the electrical connector 18 through the protection module 19. When the second sliding plug 16 is in a retracted state, the second sliding plug 16 is disconnected from the electrical connector 18 through the protection module 19.

[0084] With this configuration, when the rotary plug 12 is energized in its active state, the first sliding plug 14 and the second sliding plug 16, which are in their retracted state, are disconnected from the electrical connector 18 via the protection module 19. This ensures that the first sliding plug 14 and the second sliding plug 16 are de-energized when retracted, thus preventing electric shock to the user when touching them and improving the safety of the adapter socket 1. Similarly, when the first sliding plug 14 is energized in its active state, the second sliding plug 16 and the rotary plug 12, which are in their retracted state, are disconnected from the electrical connector 18 via the protection module 19. This ensures that the second sliding plug 16 and the rotary plug 12 are de-energized when retracted, thus preventing electric shock to the user when touching them and improving the safety of the adapter socket 1. When the second sliding plug 16 is powered on in the use state, the first sliding plug 14 and the rotating plug 12 in the storage state are disconnected from the electrical connector 18 through the protection module 19, so that the first sliding plug 14 and the rotating plug 12 in the storage state are in a power-off state, thereby preventing the user from being electrocuted when touching the first sliding plug 14 and the rotating plug 12 in the storage state, and thus improving the safety of the adapter socket 1.

[0085] There are many ways to electrically connect and disconnect the protection module 19 from the electrical connector 18. For example, the protection module 19 includes a slider that is electrically connected to the rotary plug 12. The slider can move vertically under the drive of the rotary plug 12. When the rotary plug 12 extends out of the housing 11, it drives the slider to move towards the electrical connector 18, thereby making the slider electrically connected to the electrical connector 18. When the rotary plug 12 extends into the housing 11, it drives the slider to move away from the electrical connector 18, thereby making the slider disconnected from the electrical connector 18.

[0086] For example, the protection module 19 includes a rotating plate. One end of the rotating plate is electrically connected to the rotating plug 12. The other end of the rotating plate can rotate towards or away from the electrical connector 18 under the drive of the rotating plug 12. When the rotating plug 12 extends out of the housing 11, the rotating plug 12 drives the rotating plate to rotate, causing the other end of the rotating plate to move towards the electrical connector 18, thereby making the rotating plate electrically connected to the electrical connector 18. When the rotating plug 12 extends into the housing 11, the rotating plug 12 drives the rotating plate to rotate, causing the other end of the rotating plate to move away from the electrical connector 18, thereby making the rotating plate disconnected from the electrical connector 18.

[0087] For example, the protection module 19 is fixedly installed on the first sliding plug 14 so that it moves together with the first sliding plug 14. For ease of understanding, when the first sliding plug 14 moves upward to switch to the use state, the electrical connector 18 is located above the protection module 19. When the first sliding plug 14 moves upward to switch to the use state, the protection module 19 moves upward with the first sliding plug 14 to abut against and connect with the electrical connector 18. When the first sliding plug 14 moves downward to switch to the storage state, the protection module 19 moves downward with the first sliding plug 14 to disconnect from the electrical connector 18.

[0088] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
