Description

Technical Field

[0001] This application relates to the technical field of electrical equipment, and more particularly to conversion plugs.

Background Art

[0002] There are differences in the consent among countries, and the specifications of chargers and plugs in each country are also different. In order to meet the needs of global business, going abroad, studying abroad, etc., conversion plugs with integrated plugs have emerged in the major countries of the world.

[0003] However, in related technologies, when selecting and using a set of plugs in a conversion plug, each of the remaining sets of plugs may protrude. Therefore, each of the remaining sets of plugs may accidentally protrude and the metal pins may be exposed outside, making it easy for users to come into contact with the metal pins and increasing the risk of electric shock accidents, thus increasing the safety risk during user use.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Embodiments of this application provide a conversion plug that aims to realize the mutual locking of a rotating plug and a second slide plug through the cooperation of a locking member and a stopper assembly, so that users can easily use the conversion plug.

Means for Solving the Problems

[0005] Embodiments of this application provide a conversion plug comprising a housing, a rotating plug, a locking member, a first slide plug, and a stopper assembly, wherein the rotating plug is mounted to the housing and rotatably connected to the housing via a rotating part, the first slide plug is mounted to the housing and slidable vertically relative to the housing, the stopper assembly is mounted to the housing and movably moved horizontally relative to the housing, the stopper assembly having a first stopper part and a second stopper part, and the locking member is provided in the housing and transmissibly connected to the rotating part. When the first slide plug is in a retracted state and the rotating plug switches from a retracted state to a usable state, the rotating plug linearly displaces the first stopper part, the second stopper part restricts and engages with the first slide plug, and the rotating part moves the locking member, which restricts and engages with the stopper assembly. When the rotating plug is in the retracted state and the first slide plug switches from the retracted state to the operational state, the first slide plug moves the second stopper portion linearly, and the first stopper portion restricts and engages the rotating plug.

[0006] According to the conversion plug of this application, when the rotating plug is in use, the locking member locks the first slide plug in the retracted position via the stopper assembly, and when the first slide plug is in use, the stopper assembly locks the rotating plug in the retracted position, thereby achieving mutual locking between the rotating plug and the first slide plug. This prevents the other from accidentally protruding and causing an electric shock accident when one of the rotating plug or the first slide plug is in use, thereby improving the safety of the conversion plug.

[0011] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the application. Terms used herein are solely for illustrative purposes of specific embodiments and are not intended to limit this application. The terms “and / or” as used herein include any and all combinations of one or more related items.

[0012] Referring together to Figures 1 and 2, the embodiment of the present application discloses a conversion plug 1, which comprises a housing 11, a rotating plug 12, a locking member 13, a first slide plug 14, and a stopper assembly 15. The housing 11 can be made from multiple materials; it may be made from polycarbonate, ABS, or other insulating materials, and no specific limitations are made here. The housing 11 can also have multiple shapes; it may be rectangular, cylindrical, or any other shape, and no specific limitations are made here.

[0013] The rotary plug 12 is mounted on the housing 11 and rotatably connected to the housing 11 via a rotating part 121. When the rotary plug 12 is in use, it protrudes from the housing 11 and is electrically connected to an external plug. When the rotary plug 12 is in the retracted position, it is housed on the outer surface of the housing 11.

[0014] Referring to Figures 3 and 4, the locking member 13 is provided inside the housing 11 and is transmissibly connected to the rotary plug 12. There are multiple materials for manufacturing the locking member 13; it may be made of metal or plastic, and there are no specific limitations here, but preferably the locking member 13 is made of plastic, which prevents the plug pins from contacting the locking member 13 and causing a short circuit. There are also multiple shapes for the locking member 13; it may be rectangular, cylindrical, or any other shape, and there are no specific limitations here. There are multiple ways to provide the locking member 13 inside the housing 11; it may be slidably provided inside the housing 11 or rotatably provided inside the housing 11, and there are no specific limitations here. There are multiple ways to transmissibly connect the locking member 13 to the rotary plug 12; the locking member 13 may be transmissibly connected to the rotary plug 12 by contact, or it may be transmissibly connected to the rotary plug 12 by the meshing of a gear and rack, and there are no specific limitations here.

[0015] Referring together to Figures 3 and 4, the first slide plug 14 is attached to the housing 11 and is slidable vertically relative to the housing 11. When the first slide plug 14 is in use, it protrudes from the housing 11 and is electrically connected to the external plug. When the first slide plug 14 is in the retracted position, it may be housed inside the housing 11 or on the outside of the housing 11, and no specific limitations are made here.

[0016] Referring together to Figures 3 and 4, the stopper assembly 15 is attached to the housing 11 and is horizontally movable relative to the housing 11. The stopper assembly 15 has a first stopper portion 151 and a second stopper portion 152. The first stopper portion 151 is transmissibly connected to the second stopper portion 152, the first stopper portion 151 is transmissibly connected to the rotary plug 12 by contact, and the second stopper portion 152 is transmissibly connected to the first slide plug 14 by contact. When the first slide plug 14 is in the stored position and the rotary plug 12 rotates from the stored position to the operating position, the rotary plug 12 can move the first stopper portion 151, thereby moving the second stopper portion 152 and preventing the first slide plug 14 from moving. Furthermore, the rotary plug 12 moves the locking member 13 to lock the stopper assembly 15, locking the first slide plug 14 in the stored position. When the rotating plug 12 is in the stored position and the first slide plug 14 slides from the stored position to the usable position, the first slide plug 14 moves the second stopper part 152, which in turn slides the first stopper part 151, locking the rotating plug 12 in the stored position.

[0017] The first stopper portion 151 can slide in a direction parallel to the rotation axis of the rotary plug 12, or it can slide in a direction that forms an angle with the rotation axis of the rotary plug 12, and no specific limitations are imposed here. Preferably, the first stopper portion 151 slides in a direction parallel to the rotation axis of the rotary plug 12, thereby making full use of the space in the housing 11 at the rotation axis of the rotary plug 12.

[0018] The moving direction of the second stopper portion 152 may be the same as the moving direction of the first stopper portion 151, or may form an angle with the moving direction of the first stopper portion 151, and specific limitations are not imposed here. Preferably, the first stopper portion 151 slides in a direction parallel to the rotation axis of the rotary plug 12, and the moving direction of the second stopper portion 152 is provided perpendicular to the moving direction of the first stopper portion 151. Thereby, the occupied space of the first stopper portion 151 on the rotation axis of the rotary plug 12 can be reduced, and the space of the housing 11 in the direction perpendicular to the rotation axis of the rotary plug 12 can be fully utilized. The length of the housing 11 on the rotation axis of the rotary plug 12 is reduced, and the volume of the conversion plug 1 is reduced.

[0019] There are multiple ways for the locking member 13 to lock the stopper assembly 15. The locking member 13 may lock the stopper assembly 15 by snap fit, or may lock the stopper assembly 15 by insertion, and specific limitations are not imposed here.

[0020] There are multiple ways for the locking member 13 to release the restriction on the stopper assembly 15. For example, when the rotary plug 12 rotates from the use state to the storage state, the locking member 13 releases the restriction on the stopper assembly 15 by the drive of the rotary plug 12. Also, for example, when the rotary plug 12 rotates from the use state to the storage state, the rotary plug 12 releases the restriction on the locking member 13. At this time, when the stopper assembly 15 slides to lock the rotary plug 12, the stopper assembly 15 can slide the locking member 13, and specific limitations are not imposed here.

[0021] Referring to FIG. 4, when the rotary plug 12 is in the storage state and the first slide plug 14 rotates from the storage state to the use state, the first slide plug 14 linearly moves the second stopper portion 152, and the first stopper portion 151 restricts and engages with the rotary plug 12. When the first slide plug 14 is in the use state, the first slide plug 14 restricts the second stopper portion 152, and the first stopper portion 151 cannot slide, and the first stopper portion 151 is held at a position where the rotary plug 12 is locked in the storage state. When the first slide plug 14 is in the storage state, the first slide plug 14 does not restrict the second stopper portion 152, whereby the rotary plug 12 can slide the first stopper portion 151 and can be switched to the use state.

[0022] There are multiple ways for the first stopper portion 151 to lock the rotary plug 12. The first stopper portion 151 may lock the rotary plug 12 by snap fit or by insertion, and specific limitations are not imposed here.

[0023] Referring to FIG. 3, when the first slide plug 14 is in the storage state and the rotary plug 12 rotates from the storage state to the use state, the rotary plug 12 can linearly displace the first stopper portion 151, and the second stopper portion 152 restricts and engages with the first slide plug 14. Also, the rotating portion 121 moves the locking member 13, and the locking member 13 restricts and engages with the stopper assembly 15. When the rotary plug 12 is in the use state, the rotating portion 121 restricts the locking member 13, and the locking member 13 is held at a position where the first stopper portion 151 is locked. Thereby, the second stopper portion 152 cannot slide, and the second stopper portion 152 is held at a position where the first slide plug 14 is locked in the storage state. When the rotary plug 12 is in the storage state, the rotating portion 121 does not restrict the locking member 13, whereby the locking member 13 does not restrict the first stopper portion 151, and the first slide plug 14 can slide the second stopper portion 152 and can be switched to the use state.

[0024] There are several ways in which the second stopper portion 152 locks the first slide plug 14. The second stopper portion 152 can partially enter the slide path of the first stopper assembly 15, thereby blocking the first stopper assembly 15 and switching it to the operating state. Alternatively, the second stopper portion 152 can be inserted into and fitted into the first stopper assembly 15, thereby blocking the first stopper assembly 15 and switching it to the operating state. No specific limitations are given here.

[0025] There are several ways to move the locking member 13. For example, when the rotating plug 12 rotates from the use state to the stored state, the rotating part 121 moves the locking member 13, thereby releasing the restriction on the stopper assembly 15. Also, for example, when the first slide plug 14 slides from the stored state to the use state, the first slide plug 14 slides the second stopper part 152, which drives the first stopper part 151, and the first stopper part 151 moves the locking member 13. These will not be described in detail here.

[0026] According to the conversion plug 1 of this application, when the rotating plug 12 is in use, the locking member 13 locks the first slide plug 14 in a retracted position via the stopper assembly 15, and when the first slide plug 14 is in use, the stopper assembly 15 locks the rotating plug 12 in a retracted position. This achieves mutual locking between the rotating plug 12 and the first slide plug 14, improving the safety of the conversion plug 1 by preventing the other from accidentally protruding and causing an electric shock accident when one of the rotating plug 12 or the first slide plug 14 is in use.

[0027] Referring to Figures 3 and 4, in some embodiments of this application, a crank drive unit 122 is provided on the rotating part 121, and the crank drive unit 122 is provided on the side of the rotating plug 12 that is close to the locking member 13 and is located on the rotation axis of the rotating plug 12. When the first slide plug 14 is in the stored state and the rotating plug 12 rotates from the stored state to the usable state, the crank drive unit 122 slides the locking member 13 to lock the first stopper part 151, and thus the first slide plug 14 is locked in the stored state by the second stopper part 152. With this configuration, the space on the rotation axis of the rotating plug 12 is fully utilized, the transmission structure between the rotating plug 12 and the locking member 13 is simplified, and the structure of the conversion plug 1 is simplified.

[0028] Referring to Figure 3, the crank drive unit 122 has a drive unit 1221 and a retracted unit 1222, and the distance between the drive unit 1221 and the rotation axis of the rotary plug 12 is greater than the distance between the retracted unit 1222 and the rotation axis of the rotary plug 12. When the first slide plug 14 is in the retracted state and the rotary plug 12 rotates from the retracted state to the operational state, the drive unit 1221 comes into contact with the locking member 13, moving the locking member 13 and locking the stopper assembly 15. When the rotary plug 12 is in the retracted state, the retracted unit 1222 faces the locking member 13, so sufficient movement space is provided for the locking member 13 when the first slide plug 14 switches from the retracted state to the operational state.

[0029] Furthermore, referring to Figures 2 and 3, the rotating plug 12 further includes a fitting portion 123 provided on the rotating plug 12 and located on the same plane as the crank drive unit 122 and the rotating plug 12. When the rotating plug 12 is in the stored state and the first slide plug 14 is in the use state, the stopper assembly 15 is inserted into and fitted into the fitting portion 123. With this configuration, since the crank drive unit 122 and the fitting portion 123 are provided on the same plane as the rotating plug 12, both the stopper assembly 15 and the locking member 13 are located on the same side of the rotating plug 12, simplifying the structure of the conversion plug 1. At the same time, the insertion fitting between the fitting portion 123 and the stopper assembly 15 allows the stopper assembly 15 to stably restrict the rotating plug 12.

[0030] There are several ways to insert and fit the mating portion 123 and the stopper assembly 15. For example, the mating portion 123 can be made into a convex portion, and the stopper assembly 15 can be provided with a groove into which the convex portion is inserted for fitting. Alternatively, the mating portion 123 can be made into a groove, and the stopper assembly 15 can be inserted into the groove and fitted into it. These methods will not be described in detail here.

[0031] Typically, the surface of the housing 11 has a recessed housing groove for accommodating the rotating plug 12 in its stored state, and to protect the stopper assembly 15, the stopper assembly 15 is provided in a mounting chamber within the housing 11, in which case the groove wall of the housing groove has a through hole through which the stopper assembly 15 protrudes. Considering that the mating portion 123 is a convex portion, in order to prevent the mating portion 123 from interfering with the groove wall of the housing groove when the rotating plug 12 rotates, it is necessary to separate the groove wall of the housing groove, which has a through hole, from the groove wall of the rotating plug 12 on which the mating portion 123 is provided, thereby forming a retraction passage. This allows the stopper assembly 15 to be exposed to the outside from the retraction passage when the stopper assembly 15 is inserted into and mated with the mating portion 123. In view of this, preferably, the fitting portion 123 is a recessed groove, and when the stopper assembly 15 enters the recessed groove, it is inserted into the recessed groove and fitted, and the groove wall of the housing groove, which has a through hole, and the groove wall of the rotating plug 12, which has the fitting portion 123, are in close contact, so that when the stopper assembly 15 is inserted into the fitting portion 123 and fitted, the externally exposed area of ​​the stopper assembly 15 is reduced, which provides better protection for the stopper assembly 15, and at the same time optimizes the appearance of the rotating plug 12. A drive slope 124 is provided in the recessed groove so that the rotating plug 12 can easily move the first stopper portion 151, and a contact slope 1513 is provided on the side of the first stopper portion 151 that enters the recessed groove, so that when the rotating plug 12 switches from the stored state to the use state, the drive slope 124 and the contact slope 1513 cooperate, and the first stopper portion 151 can exit from the recessed groove.

[0032] Specifically, referring to Figures 2, 3, and 5, the first stopper portion 151 has a recessed lock groove 1511 on the side closest to the locking member 13. When the first slide plug 14 is in the stored position and the rotating plug 12 is in the use position, the locking member 13 is inserted into and fitted into the lock groove 1511, thereby locking the first slide plug 14 in the stored position. In this configuration, by providing the lock groove 1511 on the side closest to the locking member 13 of the first stopper portion 151, the movement stroke of the locking member 13 is shortened, and at the same time, the locking member 13 can be more stably restricted by being inserted into and fitted into the lock groove 1511. When the first slide plug 14 is in the use position, the lock groove 1511 is offset from the locking member 13, the locking member 13 cannot enter the lock groove 1511, and the locking member 13 does not restrict the first stopper portion 151.

[0033] There are several ways in which the locking member 13 can exit the locking groove 1511. The locking member 13 may exit the locking groove 1511 by the drive of the rotating plug 12, or it may exit the locking groove 1511 by the drive of the first stopper portion 151, and no specific limitations are given here. The position in which the locking groove 1511 is provided is related to the movement of the locking member 13. For example, if the locking member 13 is slidable relative to the housing 11, the locking groove 1511 is provided on the surface of the first stopper portion 151 facing the locking member 13. Also, for example, if the locking member 13 is rotatable relative to the housing 11, the side of the locking member 13 that is close to the first stopper portion 151 is movable in the vertical direction, and the locking groove 1511 is provided on the surface of the rotating plug 12 in the vertical direction, and these will not be described in detail here. Furthermore, if the locking member 13 is rotatable relative to the housing 11, the rotation axis of the rotary plug 12 and the first stopper portion 151 may be located on the same side of the rotation axis of the locking member 13, or the rotation axis of the rotary plug 12 and the first stopper portion 151 may be located on both sides of the rotation axis of the locking member 13, and no specific limitations are imposed here.

[0034] Furthermore, referring to Figure 5, the locking member 13 has a guide slope 131 on the side adjacent to the first stopper portion 151, and the locking groove 1511 has a fitting slope 1512 on the groove surface facing the guide slope 131. When the rotating plug 12 is in the stored state and the first slide plug 14 slides from the stored state to the usage state, the first slide plug 14 can slide the first stopper portion 151 by sliding the second stopper portion 152, and the first stopper portion 151 can withdraw the locking member 13 from the locking groove 1511 by the fitting of the fitting slope 1512 and the guide slope 131. With this configuration, when the rotating plug 12 is in the stored position and the first slide plug 14 slides from the stored position to the usage position, the first stopper portion 151 can cause the locking member 13 to retract from the locking groove 1511. This eliminates the need for a structure in which the rotating plug 12 causes the locking member 13 to retract from the locking groove 1511, thus simplifying the structure of the conversion plug 1.

[0035] Referring together to Figures 2 and 5, in some embodiments of this application, a drive unit 153 is provided on one of the first stopper portion 151 and the second stopper portion 152, and an inclined chute 154 is provided on the other of the first stopper portion 151 and the second stopper portion 152, and when the drive unit 153 enters the inclined chute 154, the first stopper portion 151 and the second stopper portion 152 are transmittedly connected via the drive unit 153 and the inclined chute 154. With this configuration, when the drive unit 153 enters the inclined chute 154, the first stopper portion 151 and the second stopper portion 152 can be transmittedly connected, the transmission structure between the first stopper portion 151 and the second stopper portion 152 is simplified, and at the same time, the cooperation between the inclined chute 154 and the drive unit 153 allows the first stopper portion 151 and the second stopper portion 152 to slide in two directions that intersect each other.

[0036] It is understood that the direction of extension of the inclined chute 154 includes the direction of movement of the first stopper portion 151 and the direction of movement of the second stopper portion 152. If the first stopper portion 151 is provided with a drive unit 153, the second stopper portion 152 is provided with an inclined chute 154, and if the first stopper portion 151 is provided with an inclined chute 154, the second stopper portion 152 is provided with a drive unit 153.

[0037] Referring to Figures 2 and 6, in some embodiments of the present application, the conversion plug 1 further comprises a second slide plug 16 and a locking assembly 20, the second slide plug 16 being mounted on a housing 11 and capable of sliding perpendicularly relative to the housing 11, and the locking assembly 20 being transmissibly connected to a rotating plug 12, a first slide plug 14 and a second slide plug 16. When one of the rotating plug 12, the first slide plug 14, and the second slide plug 16 is in use, the other two are in a retracted state and are locked in the retracted state by the stopper assembly 15. This configuration improves the practicality of the conversion plug 1 by providing the second slide plug 16, and at the same time, mutual locking of the rotating plug 12, the first slide plug 14, and the second slide plug 16 is achieved, preventing electric shock accidents from occurring when one of the rotating plug 12, the first slide plug 14, and the second slide plug 16 is in use and the other two accidentally protrude. This improves the safety of the conversion plug 1.

[0038] The second slide plug 16 may be located on the side of the rotating plug 12 that is close to the first slide plug 14, or it may be located on the side of the rotating plug 12 that is farther from the first slide plug 14; no specific limitations are imposed here.

[0039] There are several ways in which the cooperation between the stopper assembly 15 and the lock assembly 20 can achieve mutual locking of the rotary plug 12, the first slide plug 14, and the second slide plug 16.

[0040] For example, the lock assembly 20 further comprises a first lock block and a second lock block, the first lock block being transmissibly connected to a rotary plug 12 and a second slide plug 16, and the second lock block being transmissibly connected to a first slide plug 14 and a second slide plug 16. When the rotary plug 12 switches from a retracted state to an operational state, the rotary plug 12 slides the first lock block to lock the second slide plug 16 in the retracted state. When the first slide plug 14 switches from a retracted state to an operational state, the first slide plug 14 slides the second lock block to lock the second slide plug 16 in the retracted state. When the second slide plug 16 switches from a retracted state to an operational state, the second slide plug 16 slides the first lock block to lock the rotary plug 12 in the retracted state, and the second slide plug 16 slides the second lock block to lock the first slide plug 14 in the retracted state.

[0041] Furthermore, for example, the stopper assembly 15 further comprises a first lock block, the first lock block being transmissibly connected to the second slide plug 16. When the rotary plug 12 switches from the stored state to the operational state, the rotary plug 12 slides the first stopper portion 151 to lock the second slide plug 16 in the stored state. When the first slide plug 14 switches from the stored state to the operational state, the first slide plug 14 slides the first lock block to lock the second slide plug 16 in the stored state. When the second slide plug 16 switches from the stored state to the operational state, the second slide plug 16 slides the first stopper portion 151 to lock the rotary plug 12 in the stored state, and the second slide plug 16 slides the first lock block to lock the first slide plug 14 in the stored state. We will not go into detail about each step here.

[0042] Preferably, the lock assembly 20 includes a locking portion 21, a first stopper portion 151 provided in the housing 11 and transmissibly connected to the rotary plug 12, a second stopper portion 152 mounted on the housing 11 and slidably connected to the housing 11 and transmissibly connected to the first stopper portion 151 and the first slide plug 14, and the locking portion 21 mounted on the housing 11 and transmissibly connected to the first slide plug 14, the second slide plug 16 and the second stopper portion 152.

[0043] When the rotating plug 12 is in use, the first stopper portion 151 locks the first slide plug 14 in the retracted position, the second stopper portion 152 contacts the locking portion 21, and the locking portion 21 locks the second slide plug 16 in the retracted position. When the first slide plug 14 is in use, the first stopper portion 151 locks the rotating plug 12 in the retracted position, and the locking portion 21 locks the second slide plug 16 in the retracted position. When the second slide plug 16 is in use, the locking portion 21 contacts the second stopper portion 152, the second stopper portion 152 locks the second slide plug 16 in the retracted position, and the first stopper portion 151 locks the rotating plug 12 in the retracted position.

[0044] This configuration enables mutual locking of the rotating plug 12, the first slide plug 14, and the second slide plug 16, preventing electric shock accidents caused by the other two accidentally protruding when one of the three is in use, thereby improving the safety of the conversion plug 1. At the same time, the second slide plug 16 can move the second stopper part 152 by sliding the locking part 21 and bringing it into contact with the second stopper part 152, simplifying the transmission structure by which the second slide plug 16 locks the rotating plug 12, and thus simplifying the structure of the conversion plug 1.

[0045] Specifically, the first slide plug 14 is located between the rotating plug 12 and the second slide plug 16, the first slide plug 14 is located between the second stopper portion 152 and the locking portion 21, the second stopper portion 152 and the locking portion 21 are located on the same side of the rotation axis of the rotating plug 12, and the locking portion 21 and the second stopper portion 152 can slide along the first and second sliding directions which are opposite to each other.

[0046] Referring to Figure 3, when the rotating plug 12 rotates from the stored state to the operating state, the rotating plug 12 slides the first stopper portion 151, which in turn slides the second stopper portion 152 along the second sliding direction. The second stopper portion 152 then contacts the locking portion 21, causing the locking portion 21 to slide in the second sliding direction and preventing the second slide plug 16 from moving. The rotating plug 12 also drives the locking member 13 to lock the first stopper portion 151, preventing the second stopper portion 152 and the locking portion 21 from moving. As a result, the second stopper portion 152 and the locking portion 21 can lock the first slide plug 14 and the second slide plug 16 in the stored state, respectively.

[0047] Referring to Figure 4, when the first slide plug 14 slides from the stored state to the usage state, the first slide plug 14 slides the locking part 21 in the second sliding direction, locking the second slide plug 16 in the stored state, and the first stopper part slides the second stopper part 152 in the first sliding direction, which slides the first stopper part 151, locking the rotating plug 12 in the stored state.

[0048] Referring to Figure 6, when the second slide plug 16 slides from the stored state to the usable state, the second slide plug 16 slides the locking part 21 in the first sliding direction to lock the first slide plug 14 in the stored state, and the locking part 21 comes into contact with the second stopper part 152, sliding the second stopper part 152 in the first sliding direction, and the second stopper part 152 slides the first stopper part 151 to lock the rotating plug 12 in the stored state.

[0049] For ease of understanding, the two pins of the first slide plug 14 are arranged in the first width direction, and the two pins of the second slide plug 16 are arranged in the second width direction. Preferably, the first width direction is parallel to the second width direction, which prevents interference between the first slide plug 14 and the second slide plug 16 and also makes the appearance of the conversion plug 1 more aesthetically pleasing. The first and second width directions may both be perpendicular to the rotation axis of the rotary plug 12, or they may both be parallel to the rotation axis of the rotary plug 12; no specific limitations are imposed here.

[0050] Preferably, referring to Figure 1, the first stopper portion 151 is located between the rotating plug 12 and the locking portion 21, and both the first and second width directions are parallel to the rotation axis direction of the rotating plug 12. In this case, the rotating plug 12, the first slide plug 14, and the second slide plug 16 are arranged sequentially in directions perpendicular to the first and second width directions, thereby making the appearance of the conversion plug aesthetically pleasing. At the same time, since the first stopper portion 151, the second stopper portion 152, and the locking portion 21 are all provided on the same side of the first slide plug 14 in the first width direction, the space occupied by the stopper assembly 15 is reduced, the design of the stopper assembly 15 is simplified, and thus the volume of the conversion plug 1 is reduced and the structure of the conversion plug 1 is simplified.

[0051] Referring to Figure 2, the first slide plug 14 comprises a first slide plug body 141 and a first drive member 142, the first slide plug body 141 being mounted on the housing 11 and slidable relative to the housing 11, and the first drive member 142 being transmissibly connected to the first slide plug body 141 and partially protruding outside the housing 11. The second slide plug 16 comprises a second slide plug body 161 and a second drive member 162, the second slide plug body 161 being mounted on the housing 11 and slidable relative to the housing 11, and the second drive member 162 being transmissibly connected to the second slide plug body 161 and partially protruding outside the housing 11.

[0052] Referring to Figure 3, when the rotating plug 12 is in use, the second stopper portion 152 blocks the first drive member 142, and the locking portion 21 blocks the second drive member 162, thereby locking the first slide plug 14 and the second slide plug 16 in their stored positions.

[0053] Referring to Figure 4, when the first slide plug 14 is in use, the locking part 21 prevents the second drive member 162, thereby locking the second slide plug 16 in the stored position.

[0054] Referring to Figure 6, when the second slide plug 16 is in use, the locking part 21 prevents the first drive member 142, thereby locking the first slide plug 14 in the stored position.

[0055] This configuration allows the user to slide the first slide plug body 141 and the second slide plug body 161, respectively, via the portions of the first drive member 142 and the second drive member 162 that protrude from the housing 11. This allows the user to easily switch between the first slide plug 14 and the second slide plug 16 between the operational and retracted states, and to easily use the conversion plug 1. At the same time, the second stopper portion 152 and the locking portion 21 block the first drive member 142, locking the first slide plug 14 in the retracted state, and the locking portion 21 block the second drive member 162, locking the second slide plug 16 in the retracted state, thus simplifying the structure of the stopper assembly 15.

[0056] Specifically, referring to Figure 3, when the rotating plug is in use, the locking member 13 is restricted by the rotating plug 12, and the locking member 13 restricts the first stopper portion 151. The first stopper portion 151 is transmissibly connected to the second stopper portion 152, and because the first stopper portion 151 is restricted, the second stopper portion 152 cannot move, thus blocking the first drive member 142 and restricting the locking portion 21, and the locking portion 21 blocks the second drive member 162.

[0057] Referring to Figure 4, when the first slide plug 14 is in use, the first drive member 142 restricts the second stopper portion 152. Since the first stopper portion 151 is transmissibly connected to the second stopper portion 152 and the second stopper portion 152 is restricted, the first stopper portion 151 cannot move and restricts the rotating plug 12, the first drive member 142 restricts the lock portion 21, and the lock portion 21 prevents the second drive member 162.

[0058] Referring to Figure 6, when the second slide plug 16 is in use, the second drive member 162 restricts the locking portion 21 and, via the locking portion 21, restricts the second stopper portion 152, causing the locking portion 21 to block the first drive member 142. The first stopper portion 151 is transmissibly connected to the second stopper portion 152, and because the second stopper portion 152 is restricted, the first stopper portion 151 cannot move and thus restricts the rotation plug 12.

[0059] Furthermore, referring to Figures 7 and 8, the first drive member 142 is attached to the first slide plug body 141 and is slidable relative to the first slide plug body 141, thereby allowing it to be switched between an unlocked position and a locked position. When the first slide plug 14 is in use and the first drive member 142 is in the locked position, the first drive member 142 cooperates with the second stopper portion 152 and / or lock portion 21 to lock the first slide plug body 141 in use. When the first drive member 142 is in the unlocked position, the first slide plug 14 can be switched between a stored state and a used state. This configuration prevents the first slide plug from switching from the used state to the stored state due to the conversion plug 1 shaking, allowing the user to easily use the conversion plug 1.

[0060] Furthermore, when the first slide plug 14 is in use, it is necessary to restrict the second stopper portion 152 and the locking portion 21. There are multiple ways in which the first slide plug 14 restricts the second stopper portion 152 and the locking portion 21, and the first slide plug 14 cooperates with the second stopper portion 152 and / or the locking portion 21 to lock the first slide plug body 141 in use. For ease of understanding, we define that when the first slide plug 14 slides upward, it switches to the use state, and when the first slide plug 14 slides downward, it switches to the stored state.

[0061] For example, the first drive member 142 is provided with an engaging portion and a connecting portion located above the engaging portion. When the first slide plug 14 is in use and the first drive member 142 is in the locked position, the engaging portion is positioned between the second stopper portion 152 and the locking portion 21, thereby restricting the movement of the second stopper portion 152 and the locking portion 21. The connecting portion is then placed over the second stopper portion 152 and / or the locking portion 21, thereby restricting the downward sliding of the first drive member 142 and locking the first slide plug body 141 in use.

[0062] Furthermore, for example, a limiting portion 1421 may be provided on the first drive member 142, and a stopper groove 17 may be provided on the second stopper portion 152 and / or locking portion 21. When the limiting portion 1421 is fitted into the stopper groove 17, the second stopper portion 152 and the locking portion 21 are restricted, and at the same time, the downward sliding of the first drive member 142 is restricted, and the first slide plug body 141 is locked in the operating state. A detailed explanation of each step will not be provided here.

[0063] Preferably, referring together to Figures 7 and 8, the first drive member 142 is provided with a limiting portion 1421, and the second stopper portion 152 and / or locking portion 21 are provided with a stopper groove 17. When the first slide plug 14 is in use and the first drive member 142 is in the locked position, the limiting portion 1421 is inserted into and fitted into the stopper groove 17. When the first drive member 142 switches from the locked position to the unlocked position, the limiting portion 1421 retracts from the stopper groove 17, the restriction on the first drive member 142 is released, and the first slide plug 14 can switch to the stored position. In this way, by inserting and fitting the limiting portion 1421 into the stopper groove 17, restrictions on the second stopper portion 152 and locking portion 21, and restrictions on the first drive member 142 are realized, and the structure of the conversion plug 1 is simplified.

[0064] When the first slide plug 14 is in use and the first drive member 142 is in the locked position, the limiting portion 1421 is inserted into and fitted into the stopper groove 17. When it is necessary to slide the first slide plug 14 to the stored position, first the first drive member 142 is switched to the unlocked position, and the limiting portion 1421 disengages from the stopper groove 17, allowing the first drive member 142 to slide the first slide plug body 141. This prevents the first slide plug from switching from the use state to the stored state due to the conversion plug 1 shaking, and allows the user to easily use the conversion plug 1.

[0065] In some embodiments of this application, the first slide plug 14 further comprises an elastic member 143, one end of which abuts against the first slide plug body 141 and the other end of which abuts against the first drive member 142, thereby causing the first drive member 142 to have a tendency to move from the unlocked position to the locked position. With this configuration, the elastic member 143 can stabilize the limiting portion 1421 in the locked position, thereby allowing the first slide plug 14 to be stabilized in a usable state, and enabling the user to easily use the conversion plug 1.

[0066] The first drive member 142 is sequentially provided with a drive unit, a connecting unit, a limiting unit 1421, and a transmission unit. The drive unit protrudes from the housing, and the transmission unit is connected to the first slide plug body 141 in a transmissible manner. Because the limiting unit 1421 is inserted into and fitted into the stopper groove 17, a portion of the width of the limiting unit 1421 is greater than the maximum distance between the second stopper unit 152 and the locking unit 21. As a result, when the first slide plug 14 is in the stored position and the first drive member 142 is in the locked position, the limiting unit 1421 cannot pass between the second stopper unit 152 and the locking unit 21, and the first slide plug 14 cannot be switched to the usable state. The first slide plug 14 can only be switched from the stored state to the usable state when the first drive member 142 is switched to the unlocked position. This prevents the first slide plug 14 from being switched to the usable state due to the conversion plug 1 shaking, and allows the user to easily store the conversion plug 1. It is understood that when the first slide plug 14 is switched to the operating state, the first drive member 142 slides the second stopper portion and lock portion via the connecting portion.

[0067] Referring together to Figures 2 and 4, in some embodiments of this application, the second stopper portion 152 is provided with a first inclined portion 1521 on the side adjacent to the first slide plug 14, and when the first slide plug 14 slides to the use position, the first slide plug 14 cooperates with the first inclined portion 1521 to slide the second stopper portion 152 in the first sliding direction. With this configuration, by simply providing the first inclined portion 1521 on the second stopper portion 152, the movement of the first drive member 142 protruding from the housing 11 can be associated with the movement of the second stopper portion 152 in the first sliding direction, and the overall structure of the conversion plug 1 is simplified.

[0068] Referring together to Figures 2 and 4, in some embodiments of this application, the locking portion 21 is provided with a second inclined portion 211 on the side adjacent to the first slide plug 14. When the first slide plug 14 slides to the use position, the first slide plug 14 cooperates with the second inclined portion 211 to slide the locking portion 21 in the second sliding direction. With this configuration, by simply providing the second inclined portion 211 on the locking portion 21, the movement of the second drive member 162 protruding from the housing 11 can be associated with the movement of the locking portion 21 in the second sliding direction, and the overall structure of the conversion plug 1 is simplified.

[0069] Referring together to Figures 2 and 6, in some embodiments of this application, the locking portion 21 is provided with a third inclined portion 212 on the side adjacent to the second slide plug 16. When the second slide plug 16 slides into the use position, the second slide plug 16 cooperates with the third inclined portion 212 to slide the locking portion 21 in the first sliding direction. With this configuration, by simply providing the locking portion 21 with a third inclined portion 212, the movement of the second drive member 162 protruding from the housing 11 can be associated with the movement of the locking portion 21 in the first sliding direction, and the overall structure of the conversion plug 1 is simplified.

[0070] Considering the increased length of European standard plug pins, when the European standard plug slides relative to the housing 11, the distance between the housing 11 opposite the external plug and the external plug is long when the European standard plug is connected to the external plug. As a result, the center of gravity of the adapter plug is farther from the external plug, making it more likely to fall out. In view of this, referring to Figures 1 and 3, the rotating plug 12 is a European standard plug. With this configuration, when the European standard plug is connected to the external plug, the distance between the housing 11 opposite the external plug and the external plug can be shortened. This positions the center of gravity of the adapter plug closer to the external plug, resulting in a more stable connection of the adapter plug to the external plug.

[0071] Referring to Figure 2, in some embodiments of this application, the conversion plug 1 further comprises an electrical connector 18 and a protection module 19, wherein the electrical connector 18 is mounted on a housing 11 and 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 by the protection module 19, and when the rotary plug 12 is in storage, the rotary plug 12 is disconnected from the electrical connector 18 by the protection module 19. When the first slide plug 14 is in use, the second slide plug 16 is electrically connected to the electrical connector 18 by the protection module 19, and when the second slide plug 16 is in storage, the second slide plug 16 is disconnected from the electrical connector 18 by the protection module 19.

[0072] With this configuration, when the rotating plug 12 in use is energized, the first slide plug 14 and the second slide plug 16 in the retracted state are disconnected from the electrical connector 18 by the protection module 19, and the first slide plug 14 and the second slide plug 16 in the retracted state become de-energized, preventing electric shock when a user touches the first slide plug 14 and the second slide plug 16 in the retracted state and improving the safety of the conversion plug 1. When the first slide plug 14 in use is energized, the second slide plug 16 and the rotating plug 12 in the retracted state are disconnected from the electrical connector 18 by the protection module 19, and the second slide plug 16 and the rotating plug 12 in the retracted state become de-energized, preventing electric shock when a user touches the second slide plug 16 and the rotating plug 12 in the retracted state and improving the safety of the conversion plug 1. When the second slide plug 16 in use is energized, the first slide plug 14 and rotary plug 12 in the retracted state are disconnected from the electrical connector 18 by the protection module 19, and the first slide plug 14 and rotary plug 12 in the retracted state are de-energized, preventing electric shock if the user touches the first slide plug 14 and rotary plug 12 in the retracted state, thereby improving the safety of the conversion plug 1.

[0073] There are several ways to electrically connect and disconnect the protection module 19 to the electrical connector 18. For example, the protection module 19 has a slider, which is electrically connected to a rotary plug 12, and the slider can be moved vertically by the drive of the rotary plug 12. When the rotary plug 12 protrudes from the housing 11, the rotary plug 12 moves the slider toward the electrical connector 18, and the slider is electrically connected to the electrical connector 18. When the rotary plug 12 retracts into the housing 11, the rotary plug 12 moves the slider toward the electrical connector 18, and the slider is disconnected from the electrical connector 18.

[0074] Furthermore, for example, the protection module 19 includes a rotating plate, one end of which is electrically connected to a rotating plug 12, and the other end of the rotating plate rotates in a direction toward or toward the electrical connector 18 by the drive of the rotating plug 12. When the rotating plug 12 protrudes from the housing 11, the rotating plug 12 rotates the rotating plate, moving the other end of the rotating plate toward the electrical connector 18, and the rotating plate is electrically connected to the electrical connector 18. When the rotating plug 12 enters the housing 11, the rotating plug 12 rotates the rotating plate, moving the other end of the rotating plate toward the electrical connector 18, and the rotating plate is disconnected from the electrical connector 18.

[0075] Furthermore, for example, the protection module 19 is fixedly attached to the first slide plug 14 and moves together with the first slide plug 14. For ease of understanding, when the first slide plug 14 moves upward to switch to the operational state, the electrical connector 18 is located above the protection module 19. When the first slide plug 14 moves upward to switch to the operational state, the protection module 19 moves upward with the first slide plug 14 and contacts the electrical connector 18, making an electrical connection. When the first slide plug 14 moves downward to switch to the retracted state, the protection module 19 moves downward with the first slide plug 14 and is disconnected from the electrical connector 18.

[0076] The foregoing 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 are all within the scope of protection of this application.
