Description

Technical Field

[0001] This application belongs to the field of power strip technology, and specifically relates to a power strip device. Background Technology

[0002] A wireless multi-socket power strip is a device with one plug and multiple outlets, serving to expand the number of outlets and making it more convenient to use multiple appliances. However, traditional multi-socket power strips are generally quite thick, making them difficult to store and resulting in poor portability. Summary of the Invention

[0003] The purpose of this application is to provide a power strip device that addresses the technical problem of poor portability in existing multi-outlet power strips.

[0004] To achieve the above objectives, the technical solution adopted in this application is: a power strip device, including a housing and a rotating plug. The housing has a receiving cavity and a socket hole for connecting to an external plug. The housing is foldable and extendable along its thickness direction. The rotating plug is rotatably connected to the housing. The rotating plug can switch between a use state and a storage state by rotating relative to the housing. The rotating plug includes an internal part and an external part connected to each other. When the rotating plug is in the use state, the internal part is located inside the receiving cavity and the external part is located outside the receiving cavity. When the rotating plug is switched from the use state to the storage state, the space occupied by the internal part in the receiving cavity in the thickness direction of the housing decreases, so that the housing can be folded along its thickness direction.

[0005] Furthermore, the outer shell includes a nested top shell assembly and a bottom cover, the top shell assembly and the bottom cover forming an accommodating cavity, the top shell assembly and the bottom cover being movable relative to each other along the thickness direction of the outer shell, and the inner part being rotatably connected to the bottom cover; When the rotating plug is switched from the storage state to the use state, the end of the internal part away from the external part abuts against the top shell assembly, causing the top shell assembly to move away from the bottom cover relative to the bottom cover; when the rotating plug is switched from the use state to the storage state, the end of the internal part away from the external part moves towards the bottom cover, causing the internal part and the bottom cover to fold together, thereby reducing the space occupied by the internal part in the accommodating cavity in the thickness direction of the outer shell.

[0006] Furthermore, the power strip device also includes a support frame and a rotating leg, both of which are located within the receiving cavity. The end of the internal part away from the external part, the support frame, the rotating leg, and the bottom cover are sequentially rotatably connected. When the rotating plug is switched from the storage state to the use state, the support frame abuts against the top shell assembly, causing the top shell assembly to move away from the bottom cover relative to the bottom cover; when the rotating plug is switched from the use state to the storage state, the internal part drives the support frame to move closer to the bottom cover, and the internal part, the support frame, and the rotating feet are all folded with the bottom cover.

[0007] Furthermore, the support frame includes a connecting rod, a first support rod, and a second support rod. The connecting rod is rotatably connected to the end of the internal part away from the external part. The opposite ends of the connecting rod are respectively fixedly connected to one end of the first support rod and one end of the second support rod. The rotating foot includes a first rotating foot and a second rotating foot. One end of the first rotating foot is rotatably connected to the end of the first support rod away from the connecting rod, and the other end of the first rotating foot is rotatably connected to the bottom cover. One end of the second rotating foot is rotatably connected to the end of the second support rod away from the connecting rod, and the other end of the second rotating foot is rotatably connected to the bottom cover.

[0008] Furthermore, the line connecting the end of the built-in part rotatably connected to the support frame and the end of the built-in part rotatably connected to the bottom cover is the first connecting line; the line connecting the end of the support frame rotatably connected to the built-in part and the end of the support frame rotatably connected to the rotating leg is the second connecting line; and the line connecting the end of the rotating leg rotatably connected to the support frame and the end of the rotating leg rotatably connected to the bottom cover is the third connecting line. When the outer shell is fully unfolded along its thickness direction, the first connecting line and the third connecting line are both perpendicular to the second connecting line, and the second connecting line is parallel to the top shell assembly and the bottom cover.

[0009] Furthermore, a first magnetic clasp is fixedly installed on the top shell assembly, and a second magnetic clasp is fixedly installed on the bottom cover. When the shell is fully folded along the thickness direction, the first magnetic clasp and the second magnetic clasp are magnetically connected.

[0010] Furthermore, the top shell assembly includes a top cover and a middle frame, the middle frame being at least partially inserted into the top cover, and the middle frame and the top cover being movable relative to each other along the thickness direction of the shell; the bottom cover is at least partially inserted into the middle frame, and the bottom cover and the middle frame being movable relative to each other along the thickness direction of the shell.

[0011] Furthermore, the top cover includes a top plate and a first side panel surrounding the top plate, and the bottom cover includes a bottom plate and a second side panel surrounding the bottom plate. The bottom plate and the top plate are parallel and opposite to each other. The middle frame is at least partially inserted into the first side panel, and the second side panel is at least partially inserted into the middle frame. A first snap-fit ​​protrusion is provided on the side of the second side panel near the top plate and facing the middle frame. A second snap-fit ​​protrusion is provided on the side of the middle frame near the bottom plate and facing the second side panel. The first snap-fit ​​protrusion is used to snap onto the side of the second snap-fit ​​protrusion facing the top plate. A third snap-fit ​​protrusion is provided on the side of the middle frame near the top plate and facing the second side panel. The third snap-fit ​​protrusion is used to snap onto the side of the second side panel near the top plate.

[0012] Furthermore, a fixing post is provided on the side of the top plate facing the bottom plate, and an anti-detachment structure is provided at the end of the fixing post away from the top plate. A fixing sleeve is provided on the side of the bottom plate facing the top plate, and a first anti-detachment protrusion is provided on the inner side of the end of the fixing sleeve near the top plate. The plug-in device also includes a connecting sleeve, which is axially movably sleeved on the fixing post and inserted into the fixing sleeve. A second anti-detachment protrusion is provided on the outer side of the end of the connecting sleeve away from the top plate. The first anti-detachment protrusion is used to lock onto the side of the second anti-detachment protrusion facing the top plate. A third anti-detachment protrusion is provided on the inner side of the end of the connecting sleeve near the top plate. The third anti-detachment protrusion is used to lock onto the side of the anti-detachment structure facing the top plate.

[0013] Furthermore, the outer surface of the housing is provided with a storage groove, and when the rotating plug is switched from the use state to the storage state, the external part is at least partially inserted into the storage groove.

[0014] Compared with existing technologies, the advantages of the power strip device provided in this application are as follows: In use, the external part of the rotating plug, which is in use, is plugged into an external power socket, and the plug of an electrical appliance is inserted into the socket hole of the outer casing, thereby supplying power to the appliance. When not in use, the plug of the electrical appliance is unplugged, and the rotating plug is rotated to switch the rotating plug from the use state to the storage state. During this process, the internal part of the rotating plug occupies less space in the accommodating cavity in the thickness direction of the outer casing, allowing the outer casing to fold along the thickness direction. This reduces the thickness of the power strip device, making it easier to store and improving portability. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] Please refer to the following: Figures 1 to 4 This application provides a power strip device, including a housing 10 and a rotating plug 20. The housing 10 has a receiving cavity 11 and a socket hole 13 for connecting to an external plug. The housing 10 is foldable and extendable along its thickness direction. The rotating plug 20 is rotatably connected to the housing 10. The rotating plug 20 can switch between a use state and a storage state by rotating relative to the housing 10. The rotating plug 20 includes an internal part 21 and an external part 22 connected to each other. When the rotating plug 20 is in the use state, the internal part 21 is located inside the receiving cavity 11, and the external part 22 is located outside the receiving cavity 11. When the rotating plug 20 is switched from the use state to the storage state, the space occupied by the internal part 21 in the receiving cavity 11 in the thickness direction of the housing 10 becomes smaller, so that the housing 10 can be folded along the thickness direction.

[0022] Figure 1 The rotary plug 20 shown is in use, and the housing 10 is fully extended along the thickness direction. Figure 4 The rotary plug 20 shown is in a retracted state, with the outer casing 10 completely folded along its thickness. In use, the external part 22 of the rotary plug 20 (in use) is plugged into an external power outlet, and the plug of an electrical appliance is inserted into the socket 13 of the outer casing 10 to supply power to the appliance. When not in use, the plug of the electrical appliance is unplugged, and the rotary plug 20 is rotated to switch it from the use state to the retracted state. During this process, the internal part 21 of the rotary plug 20 occupies less space in the receiving cavity 11 along the thickness direction of the outer casing 10, allowing the outer casing 10 to fold along its thickness, thereby reducing the thickness of the power strip and making it easier to store and improve portability. When using it again, the rotary plug 20 is rotated to switch it from the retracted state to the use state. During this process, the internal part 21 occupies more space in the receiving cavity 11 along the thickness direction of the outer casing 10, therefore the outer casing 10 needs to be unfolded along its thickness direction.

[0023] The number of socket holes 13 is not limited and can be multiple sets. One set of socket holes 13 is used to connect to one external plug. One set of socket holes 13 includes multiple holes, and the number of holes matches the number of prongs on the plug, thus enabling the simultaneous connection of multiple external plugs, expanding the number of outlets and making it more convenient to use multiple appliances. The socket holes 13 and the rotary plug 20 can adopt American Standard, Japanese Standard, Chinese Standard, British Standard, Australian Standard, or Argentine Standard, etc. The rotary plug 20 can be a two-prong plug or a three-prong plug. The three-prong plug has a ground prong, a neutral prong, and a live prong, while the two-prong plug only has a neutral prong and a live prong.

[0024] In some embodiments, combined with Figure 3 and Figure 4As shown, the outer surface of the housing 10 is provided with a storage groove 12. When the rotary plug 20 is switched from the use state to the storage state, the external part 22 of the rotary plug 20 is at least partially inserted into the storage groove 12. By providing a storage groove 12 on the outer surface of the housing 10, the external part 22 of the rotary plug 20 can be at least partially inserted into the storage groove 12 when the rotary plug 20 is switched from the use state to the storage state. This further reduces the thickness of the power strip, making the power strip easier to store and improving portability. It should be noted that "the external part 22 is at least partially inserted into the receiving cavity 11" means that the external part 22 can be completely inserted into the receiving cavity 11, or only partially inserted into the receiving cavity 11, while a portion remains outside the receiving cavity 11. This makes it easier for the user to grasp the external part 22 to rotate the rotary plug 20. Specifically, the built-in part 21 and the external part 22 are fixedly connected, so that when the user rotates the external part 22, the built-in part 22 can move together with the external part 22. When the external part 22 enters the storage slot 12, the space occupied by the built-in part 21 in the accommodating cavity 11 in the thickness direction of the outer shell 10 becomes smaller.

[0025] In some embodiments, the housing 10 is further provided with a through-hole (not shown), the storage groove 12 and the receiving cavity 11 are connected through the through-hole, and the external part 22 and the internal part 21 of the rotating plug 20 are connected through the through-hole.

[0026] In some embodiments, the knot and Figure 1 and Figure 2 As shown, the outer casing 10 includes a nested top shell assembly 14 and a bottom cover 15, which together form an accommodating cavity 11. The top shell assembly 14 and the bottom cover 15 are movable relative to each other along the thickness direction of the outer casing 10. The inner part 21 is rotatably connected to the bottom cover 15, and the storage slot 12 is provided on the bottom cover 15. When the rotating plug 20 is switched from the storage state to the use state, the end of the inner part 21 away from the outer part 22 abuts against the top shell assembly 14, causing the top shell assembly 14 to move away from the bottom cover 15 relative to the bottom cover 15. When the rotating plug 20 is switched from the use state to the storage state, the end of the inner part 21 away from the outer part 22 moves towards the bottom cover 15, causing the inner part 21 and the bottom cover 15 to fold, thereby reducing the space occupied by the inner part 21 in the accommodating cavity 11 in the thickness direction of the outer casing 10.

[0027] Specifically, the bottom cover 15 is movably inserted into the top shell assembly 14. During use, one hand can grasp the top shell assembly 14 while the other hand rotates the rotating plug 20 to switch it from a retracted state to a usable state. During this process, the outer portion 22 of the rotating plug 20 extends out of the storage slot 12 for connection to an external power socket. The inner portion 21 of the rotating plug 20, away from the outer portion 22, abuts against the top shell assembly 14 and tends to push the top shell assembly 14 away from the bottom cover 15. The bottom cover 15, rotatably connected to the inner portion 21, moves away from the top cover 16 under the reaction force, thereby causing the outer shell 10 to unfold along its thickness direction. In other words, rotating the rotating plug 20 can trigger the unfolding of the outer shell 10 along its thickness direction, making operation more convenient. When the rotating plug 20 is successfully switched to the usable state, the outer shell 10 is fully unfolded along its thickness direction. When not in use, the rotating plug 20 is rotated in the reverse direction to switch it from the active state to the retracted state. During this process, the outer part 22 of the rotating plug 20 retracts into the storage slot 12, and the inner part 21 of the rotating plug 20 moves away from the outer part 22 towards the bottom cover 15, causing the inner part 21 and the bottom cover 15 to fold together. This reduces the space occupied by the inner part 21 in the accommodating cavity 11 in the thickness direction of the outer shell 10, thereby pushing the bottom cover 15 towards the top shell assembly 14, causing the outer shell 10 to fold along the thickness direction. When the rotating plug 20 is successfully switched to the retracted state, the outer shell 10 is completely folded along the thickness direction.

[0028] Of course, in some other embodiments, the bottom cover 15 can also be movably fitted onto the top shell assembly 14. In this case, one hand can grasp the bottom cover 15 and the other hand can rotate the rotating plug 20 to switch the rotating plug 20 from the storage state to the use state. During this process, the outer part 22 of the rotating plug 20 extends out of the storage slot 12, and the inner part 21 of the rotating plug 20 abuts against the top shell assembly 14 away from the outer part 22 and directly pushes the top shell assembly 14 to move away from the bottom cover 15, thereby causing the outer shell 10 to unfold along the thickness direction.

[0029] In some embodiments, combined with Figure 7 and Figure 9As shown, the power strip device also includes a support frame 30 and a rotating leg 40. Both the support frame 30 and the rotating leg 40 are disposed within the receiving cavity 11. The end of the internal part 21 away from the external part 22, the support frame 30, the rotating leg 40, and the bottom cover 15 are sequentially rotatably connected. When the rotating plug 20 is switched from the storage state to the use state, the support frame 30 abuts against the top shell assembly 14, causing the top shell assembly 14 to move away from the bottom cover 15 relative to it, or causing the bottom cover 15 to move away from the top shell assembly 14 under the drive of a reaction force. When the rotating plug 20 is switched from the use state to the storage state, the internal part 21 drives the support frame 30 to move closer to the bottom cover 15, so that the internal part 21, the support frame 30, and the rotating leg 40 are all folded with the bottom cover 15.

[0030] Specifically, the bottom cover 15 is movably inserted into the top shell assembly 14. In use, one hand grasps the top shell assembly 14, and the other hand rotates the rotating plug 20 to switch the rotating plug 20 from the storage state to the use state. During this process, the external part 22 of the rotating plug 20 extends out of the storage slot 12, and the internal part 21 of the rotating plug 20 causes the support frame 30 to abut against the top shell assembly 14 and tends to push the top shell assembly 14 away from the bottom cover 15. The bottom cover 15, which is rotatably connected to the internal part 21, moves away from the top shell assembly 14 under the drive of the reaction force, thereby causing the outer shell 10 to unfold along the thickness direction. When not in use, rotate the rotating plug 20 in the reverse direction to switch the rotating plug 20 from the use state to the storage state. During this process, the external part 22 of the rotating plug 20 is put into the storage slot 12, and the internal part 21 of the rotating plug 20 drives the support frame 30 to move towards the bottom cover 15, so that the internal part 21, the support frame 30 and the rotating foot 40 are all folded with the bottom cover 15, so as to reduce the space occupied by the internal part 21, the support frame 30 and the rotating foot 40 in the thickness direction of the outer shell 10 in the accommodating cavity 11, thereby pushing the bottom cover 15 towards the top shell assembly 14, so that the outer shell 10 is folded along the thickness direction.

[0031] Specifically, when the support frame 30 abuts against the top shell assembly 14 and tends to push the top shell assembly 14 to move away from the bottom cover 15, the reaction force from the top shell assembly 14 on the support frame 30 will be transmitted to the built-in part 21 of the rotary plug 20 and then to the bottom cover 15. On the other hand, it will be transmitted to the rotating leg 40 and then to the bottom cover 15. In other words, multiple points of force can be formed on the bottom cover 15 to stably push the bottom cover 15 to move away from the top shell assembly 14. Compared to the built-in part 21 directly abutting against the top shell assembly 14, by providing a support frame 30 between the built-in part 21 and the top shell assembly 14, and having the support frame 30 abut against the top shell assembly 14, the rotary plug 20 can be protected, reducing wear on the rotary plug 20. In addition, when the outer shell 10 is fully unfolded along the thickness direction, the support frame 30, the rotating support leg 40 and the built-in part 21 can work together to support the top shell assembly 14 and the bottom cover 15, which can better maintain the shape of the outer shell 10 after unfolding, prevent the outer shell 10 from folding at will, and ensure the normal use of the product.

[0032] Of course, in some other embodiments, the bottom cover 15 can also be movably fitted onto the top shell assembly 14. In this case, one hand can grasp the bottom cover 15 and the other hand can rotate the rotating plug 20 to switch the rotating plug 20 from the storage state to the use state. During this process, the outer part 22 of the rotating plug 20 extends out of the storage slot 12, and the inner part 21 of the rotating plug 20 causes the support frame 30 to abut against the top shell assembly 14. The support frame 30 directly pushes the top shell assembly 14 to move away from the bottom cover 15, thereby causing the outer shell 10 to unfold along the thickness direction.

[0033] In some embodiments, the line connecting one end of the built-in part 21 rotatably connected to the support frame 30 and the end of the built-in part 21 rotatably connected to the bottom cover 15 is the first connecting line; the line connecting one end of the support frame 30 rotatably connected to the built-in part 21 and the end of the support frame 30 rotatably connected to the rotating leg 40 is the second connecting line; and the line connecting one end of the rotating leg 40 rotatably connected to the support frame 30 and the end of the rotating leg 40 rotatably connected to the bottom cover 15 is the third connecting line. Both the first and third connecting lines are perpendicular to the second connecting line, and the second connecting line is parallel to the top shell assembly 14 and the bottom cover 15. When the outer shell 10 is fully unfolded along its thickness direction, both the first and third connecting lines are perpendicular to the second connecting line, and the second connecting line is parallel to the top shell assembly 14 and the bottom cover 15. That is, the first, second, and third connecting lines, together with the bottom cover 15, can form a rectangular frame, thereby stably supporting the top shell assembly 14 and the bottom cover 15, better maintaining the shape of the unfolded outer shell 10, preventing the outer shell 10 from folding arbitrarily, and ensuring the normal use of the product.

[0034] In some embodiments, such as Figure 7As shown, the rotating support 40 includes a first rotating support 41 and a second rotating support 42. The support frame 30 includes a connecting rod 31, a first support rod 32, and a second support rod 33. The connecting rod 31 is rotatably connected to the built-in part 21 of the rotating plug 20. The opposite ends of the connecting rod 31 are respectively fixedly connected to one end of the first support rod 32 and one end of the second support rod 33. One end of the first rotating support 41 is rotatably connected to the end of the first support rod 32 away from the connecting rod 31. The other end of the first rotating support 41 is rotatably connected to the bottom cover 15. One end of the second rotating support 42 is rotatably connected to the end of the second support rod 33 away from the connecting rod 31. The other end of the second rotating support 42 is rotatably connected to the bottom cover 15.

[0035] In use, hold the top shell assembly 14 with one hand and rotate the rotating plug 20 with the other hand to switch the rotating plug 20 from the storage state to the use state. During this process, the outer part 22 of the rotating plug 20 extends out of the storage slot 12, and the inner part 21 of the rotating plug 20 causes the connecting rod 31, the first support rod 32, and the second support rod 33 to abut against the top shell assembly 14, and tend to push the connecting rod 31, the first support rod 32, and the second support rod 33 in a direction away from the bottom cover 15. The connecting rod 31 receives a reaction force from the top shell assembly 14. The force applied is transmitted to the built-in portion 21 of the rotary plug 20, and then to the bottom cover 15. The reaction force from the top shell assembly 14 on the first support rod 32 is transmitted to the first rotating leg 41, and then to the bottom cover 15. The reaction force from the top shell assembly 14 on the second support rod 33 is transmitted to the second rotating leg 42, and then to the bottom cover 15. This creates multiple points of force application on the bottom cover 15, stably pushing the bottom cover 15 away from the top shell assembly 14. When the outer shell 10 is fully unfolded along its thickness direction, the connecting rod 31, the first support rod 32, the second support rod 33, the first rotating leg 41, the second rotating leg 42, and the built-in portion 21 of the rotary plug 20 work together to support the top shell assembly 14 and the bottom cover 15, better maintaining the shape of the unfolded outer shell 10, preventing the outer shell 10 from folding arbitrarily, and ensuring normal product use.

[0036] The number of the first rotating support leg 41 and the second rotating support leg 42 is not limited. For example, the number of the first rotating support leg 41 and the second rotating support leg 42 shown in the figure are both two. In some other embodiments, the number of the first rotating support leg 41 and the second rotating support leg 42 can be one, three, four or more.

[0037] In some embodiments, combined with Figure 7 and Figure 8As shown, the power strip device also includes a first threaded fastener 51 and a second threaded fastener 52. The first threaded fastener 51 passes through the first support rod 32 and is threadedly connected to the end of the first rotating leg 41 away from the bottom cover 15. The first threaded fastener 51 is in a state of not being fully tightened, so that the first support rod 32 and the first rotating leg 41 can rotate relative to each other. The second threaded fastener 52 passes through the second support rod 33 and is threadedly connected to the end of the second rotating leg 42 away from the bottom cover 15. The second threaded fastener 52 is in a state of not being fully tightened, so that the second support rod 33 and the second rotating leg 42 can rotate relative to each other. In some other embodiments, the first rotating leg 41 and the first support rod 32 can be connected by a pivot to achieve a rotatable connection, and the second rotating leg 42 and the second support rod 33 can also be connected by a pivot to achieve a rotatable connection.

[0038] In some embodiments, combined with Figure 7 and Figure 8 As shown, the bottom cover 15 has a first support base 151 and a second support base 152 on the side facing the accommodating cavity 11. The first support base 151 has a first connecting post 1511, and the end of the first rotating leg 41 away from the first support rod 32 is rotatably sleeved on the first connecting post 1511 to achieve a rotatable connection between the first rotating leg 41 and the bottom cover 15. The second support base 152 has a second connecting post 1521, and the end of the second rotating leg 42 away from the second support rod 33 is rotatably sleeved on the second connecting post 1521 to achieve a rotatable connection between the second rotating leg 42 and the bottom cover 15. In some other embodiments, the first rotating leg 41 and the first support base 151 can be connected by screws, with the screws not fully tightened, so that the first rotating leg 41 and the first support base 151 can rotate relative to each other. The second rotating leg 42 and the second support base 152 can also be connected by screws, with the screws not fully tightened, so that the second rotating leg 42 and the second support base 152 can rotate relative to each other.

[0039] In some embodiments, such as Figure 10 As shown, a first magnetic element 61 is fixedly installed on the top shell assembly 14, such as... Figure 8As shown, a second magnetic chuck 62 is fixedly installed on the bottom cover 15. When the outer shell 10 is fully folded along the thickness direction, the first magnetic chuck 61 and the second magnetic chuck 62 are magnetically connected. By providing the first magnetic chuck 61 on the top shell assembly 14 and the second magnetic chuck 62 on the bottom cover 15, when the outer shell 10 is fully folded along the thickness direction, the first magnetic chuck 61 and the second magnetic chuck 62 are magnetically connected, thereby fixing the top shell assembly 14 and the bottom cover 15, maintaining the shape of the outer shell 10 after it is fully folded, and preventing the outer shell 10 from unfolding arbitrarily. In addition, during the folding of the outer shell 10 along the thickness direction, when the distance between the first magnetic chuck 61 and the second magnetic chuck 62 decreases to a certain value, the top shell assembly 14 and the bottom cover 15 can automatically move towards each other under the attraction between the first magnetic chuck 61 and the second magnetic chuck 62 to fold, making the operation easier and less strenuous. Specifically, the top shell assembly 14 is provided with a first fixing groove, and the first magnetic member 61 is fixed in the first fixing groove; the bottom cover 15 is provided with a second fixing groove, and the second magnetic member 62 is fixed in the second fixing groove.

[0040] In some embodiments, combined with Figure 1 and Figure 2 As shown, the top shell assembly 14 includes a top cover 16 and a middle frame 17. The middle frame 17 is at least partially inserted into the top cover 16, and the middle frame 17 and the top cover 16 are movable relative to each other along the thickness direction of the outer shell 10. The bottom cover 15 is at least partially inserted into the middle frame 17, and the bottom cover 15 and the middle frame 17 are movable relative to each other along the thickness direction of the outer shell 10. The thickness of the outer shell 10 when fully unfolded is determined by the size of the rotating plug 20. Assuming that the thickness of the top cover 16, the bottom cover 15, and the middle frame 17 are the same, only the two-layer folding structure composed of the top cover 16 and the bottom cover 15 can reduce the thickness of the outer shell 10 to a maximum of half of its original thickness. The three-layer folding structure composed of the top cover 16, the middle frame 17, and the bottom cover 15 can further compress the thickness of the outer shell 10, reducing the thickness of the outer shell 10 to a maximum of one-third of its original thickness, making the outer shell 10 thinner and easier to store. In some embodiments, the number of middle frames 17 can be two, three or more, and multiple middle frames 17 are nested and connected in sequence. Each pair of adjacent middle frames 17 can move relative to each other along the thickness direction of the outer shell 10. When there are two middle frames 17, the top cover 16, the bottom cover 15 and the two middle frames 17 form a four-layer folding structure, which can reduce the thickness of the outer shell 10 to one-quarter of the original thickness. When there are three middle frames 17, the top cover 16, the bottom cover 15 and the three middle frames 17 form a five-layer folding structure, which can reduce the thickness of the outer shell 10 to one-fifth of the original thickness. And so on. When there are n middle frames 17, the top cover 16, the bottom cover 15 and the n middle frames 17 form an (n+2)-layer folding structure, which can reduce the thickness of the outer shell 10 to one-(n+2)th of the original thickness.

[0041] In some embodiments, such as Figure 2 As shown, the top cover 16 includes a top plate 161 and a first side panel 162 surrounding the top plate 161, and the bottom cover 15 includes a bottom plate 153 and a second side panel 154 surrounding the bottom plate 153. The bottom plate 153 and the top plate 161 are parallel and opposite to each other. The middle frame 17 is at least partially inserted into the first side panel 162, and the second side panel 154 is at least partially inserted into the middle frame 17. The second side panel 154 has a first side panel 162 on the side near the top plate 161 and facing the middle frame 17. A first snap-fit ​​protrusion 155 is provided on the side of the middle frame 17 near the bottom plate 153 and facing the second side panel 154. A second snap-fit ​​protrusion 171 is provided on the side of the second snap-fit ​​protrusion 171 facing the top plate 161. A third snap-fit ​​protrusion 172 is provided on the side of the middle frame 17 near the top plate 161 and facing the second side panel 154. The third snap-fit ​​protrusion 172 is provided on the side of the middle frame 17 near the top plate 161.

[0042] When in use, one hand can hold the top cover 16 and the other hand can rotate the rotating plug 20 to switch the rotating plug 20 from the storage state to the use state. During this process, the external part 22 of the rotating plug 20 extends out of the storage slot 12, and the internal part 21 of the rotating plug 20 abuts against the top plate 161 of the top cover 16 and tends to push the top cover 16 away from the bottom cover 15. The bottom cover 15, which is rotatably connected to the internal part 21, will move away from the top cover 16 under the reaction force. When the first snap-fit ​​protrusion 155 on the second side plate 154 of the bottom cover 15 is engaged with the second snap-fit ​​protrusion 171 of the middle frame 17 facing the top plate 161, the bottom cover 15 can drive the middle frame 17 to move away from the top cover 16 together, thereby realizing the three-layer unfolding of the outer shell 10. When not in use, rotate the rotating plug 20 in the reverse direction to switch it from the use state to the storage state. During this process, the outer part 22 of the rotating plug 20 is retracted into the storage slot 12, and the inner part 21 of the rotating plug 20 moves away from the outer part 22 towards the bottom cover 15, causing the inner part 21 to fold with the bottom plate 153 of the bottom cover 15. Then, the bottom cover 15 can be pressed to move it towards the top cover 16. When the third snap-fit ​​protrusion 172 of the middle frame 17 is engaged with the second side panel 154 of the bottom cover 15 near the top plate 161, the bottom cover 15 can drive the middle frame 17 to move towards the top cover 16. Finally, the bottom cover 15 is retracted into the middle frame 17, and the middle frame 17 is retracted into the top cover 16, realizing the three-layer folding of the outer shell 10.

[0043] Specifically, the first magnetic suction component 61 is fixedly mounted on the top plate 161 of the top cover 16, and the second magnetic suction component 62, the first support base 151 and the second support base 152 are all fixedly mounted on the bottom plate 153 of the bottom cover 15. Of course, the first support base 151 and the second support base 152 can also be fixed to the two opposite inner side walls of the second side panel 154 respectively.

[0044] In some embodiments, such as Figure 2 As shown, the second side panel 154 has a slot 156 at one end near the top panel 161, and the third snap-fit ​​protrusion 172 snaps into the slot 156. Compared to the third snap-fit ​​protrusion 172 being directly snapped onto the end face of the second side panel 154 near the top cover 16, by opening the slot 156 in the second side panel 154, the third snap-fit ​​structure can be snapped into the slot 156, which can increase the overlap between the middle frame 17 and the bottom cover 15 when folded, thereby further reducing the thickness of the outer shell 10 after folding.

[0045] In some embodiments, combined with Figure 5 and Figure 6 As shown, a fixing post 163 is provided on the side of the top plate 161 facing the bottom plate 153. An anti-detachment structure 70 is provided at the end of the fixing post 163 away from the top plate 161. A fixing sleeve 157 is provided on the side of the bottom plate 153 facing the top plate 161. A first anti-detachment protrusion 158 is provided on the inner side of the end of the fixing sleeve 157 near the top plate 161. The plug-in device also includes a connecting sleeve 80. The connecting sleeve 80 is axially movably sleeved on the fixing post 163 and inserted into the fixing sleeve 157. A second anti-detachment protrusion 81 is provided on the outer side of the end of the connecting sleeve 80 away from the top plate 161. The first anti-detachment protrusion 158 is used to lock onto the side of the second anti-detachment protrusion 81 facing the top plate 161. A third anti-detachment protrusion 82 is provided on the inner side of the end of the connecting sleeve 80 near the top plate 161. The third anti-detachment protrusion 82 is used to lock onto the side of the anti-detachment structure 70 facing the top plate 161.

[0046] During the unfolding of the outer casing 10 along the thickness direction, when the bottom cover 15 moves away from the top cover 16 until the first anti-detachment protrusion 158 of the fixing sleeve 157 is engaged with the side of the second anti-detachment protrusion 81 of the connecting sleeve 80 facing the top plate 161, the bottom cover 15 can drive the connecting sleeve 80 to move away from the top cover 16 together until the third anti-detachment protrusion 82 of the connecting sleeve 80 is engaged with the side of the anti-detachment structure 70 on the fixing post 163 facing the top plate 161, the bottom cover 15 and the middle frame 17 cannot move further away from the top cover 16, thereby preventing the bottom cover 15 from falling off. At this time, the outer casing 10 is in a fully unfolded state along the thickness direction.

[0047] In some embodiments, such as Figure 5As shown, the fixing post 163 is provided with a threaded hole 1631. The anti-detachment structure 70 includes a third threaded fastener 71, which includes a head and a rod connected together. The rod extends into the threaded hole 1631 and is threadedly connected to the threaded hole 1631. The third anti-detachment protrusion 82 is used to lock onto the side of the head facing the top plate 161. The third threaded fastener 71 enables a detachable connection between the top cover 16 and the bottom cover 15. The bottom cover 15 can be disassembled by removing the third threaded fastener 71.

[0048] In some embodiments, such as Figure 5 As shown, the anti-detachment structure 70 also includes a washer 72, which is sleeved on the rod of the third threaded fastener 71. The head of the third threaded fastener 71 presses and fixes the washer 72 to the connecting post. The third anti-detachment protrusion 82 is used to lock onto the side of the washer 72 facing the top plate 161.

[0049] In some embodiments, combined with Figure 5 and Figure 6 As shown, a fourth locking protrusion 83 is provided on the outer side of the end of the connecting sleeve 80 near the top plate 161, and a first anti-detachment protrusion 158 is used to lock onto the side of the fourth locking protrusion 83 facing away from the top plate 161. During the folding of the outer shell 10 along the thickness direction, when the bottom cover 15 moves toward the top cover 16 until the first anti-detachment protrusion 158 of the fixing sleeve 157 locks onto the side of the fourth locking protrusion 83 of the connecting sleeve 80 facing away from the top plate 161, the bottom cover 15 can drive the connecting sleeve 80 to move toward the top cover 16 together, thereby resetting the connecting sleeve 80.

[0050] In some embodiments, the number of fixing posts 163, fixing sleeves 157 and connecting sleeves 80 can be multiple, and the number of the three is the same. The multiple fixing posts 163 are respectively connected to the multiple fixing posts 163 through the multiple connecting sleeves 80.

[0051] In some embodiments, combined with Figure 1 and Figure 2 As shown, the rotary plug 20 includes multiple pins, all of which are rotatably connected to the housing 10.

The second threaded connector 102 passes through the inner part 241 of the zero electrode plug 24 and connects to one end of the outer part 242 of the zero electrode, and is then threadedly connected to the fixed bracket 90. The second threaded connector 102 is in a state of not being fully tightened, so that the zero electrode plug 24 can rotate relative to the fixed bracket 90. The inner part 251 of the ground electrode plug 25 connects to one end of the outer part 252 of the ground electrode and is rotatably connected to the fixed bracket 90 through the first rotating shaft 110. Specifically, both ends of the first rotating shaft 110 are fixedly connected to the fixed bracket 90, and the ground electrode built-in part 251 of the ground electrode pin 25 is rotatably sleeved on the first rotating shaft 110. Of course, both ends of the first rotating shaft 110 can also be rotatably connected to the fixed bracket 90, and the ground electrode built-in part 251 can be fixedly sleeved 157 on the first rotating shaft 110 or integrally formed with the first rotating shaft 110.

[0054] In addition, multiple pins of the rotary plug 20 are rotatably connected to the support frame 30. Specifically, the power strip device also includes a third threaded connector 103, a fourth threaded connector 104, and a second rotating shaft 120. The third threaded connector 103 passes through the end of the fire electrode internal portion 231 of the fire electrode pin 23 away from the fire electrode external portion 232 and is threadedly connected to the support frame 30. The third threaded connector 103 is in a state of not being fully tightened so that the fire electrode pin 23 can rotate relative to the support frame 30. The fourth threaded connector 104 passes through the end of the zero electrode internal portion 241 of the zero electrode pin 24 away from the zero electrode external portion 242 and is threadedly connected to the support frame 30.

[0055] More specifically, two first fixing seats 311 are fixedly provided on one side of the connecting rod 31 of the support frame 30. The two first fixing seats 311 are spaced apart along the length of the connecting rod 31.

[0056] In some embodiments, such as Figure 1 As shown, the socket hole 13 is located on the top shell assembly 14, specifically on the top cover 16 of the top shell assembly 14, in conjunction with... Figure 8 and Figure 10As shown, the power strip device also includes a first conductive component 130 and a second conductive component 140. The first conductive component 130 is fixedly disposed on the side of the top shell assembly 14 facing the receiving cavity 11. An external plug can pass through the socket hole 13 and be electrically connected to the first conductive component 130. The second conductive component 140 is fixedly disposed on the bottom cover 15. The rotating plug 20 is electrically connected to the second conductive component 140, and the second conductive component 140 is electrically connected to the first conductive component 130. In use, the external part 22 of the rotating plug 20, which is in use, is plugged into an external power socket, and the plug of the appliance is inserted into the socket hole 13 of the outer shell 10. Thus, the current from the external power supply can be transmitted to the appliance in sequence through the rotating plug 20, the second conductive component 140, and the first conductive component 130, thereby supplying power to the appliance.

[0057] In some embodiments, such as Figure 10 As shown, a mounting bracket 150 is fixedly mounted on the side of the top cover 16 of the top shell assembly 14 facing the accommodating cavity 11.

[0058] Specifically, the first fixing groove for fixing the first magnetic suction member 61 is provided in the mounting bracket 150, and the mounting bracket 150 can be fixed to the top cover 16 by screws. The fire electrode conductive copper sheet 141, the zero electrode conductive copper sheet 142, and the ground electrode conductive copper sheet 143 can be fixed to the fixing bracket 90 by screws. The first threaded connector 101 passes through the fire electrode conductive copper sheet 141 and the fire electrode built-in part 231 of the fire electrode pin 23 and is threadedly connected to the fixing bracket 90. The second threaded connector 102 passes through the zero electrode conductive copper sheet 142 and the zero electrode built-in part 241 of the zero electrode pin 24 and is threadedly connected to the fixing bracket 90. The first rotating shaft 110 passes through the ground electrode conductive copper sheet 143.

[0059] In some embodiments, the rotary plug 20 can also be a two-prong plug. Compared with the three-prong plug embodiment, this embodiment reduces the ground pin 25 and the linkage mechanism for the ground pin 25. The linkage mechanism includes a first rotating shaft 110 for connecting the ground pin 25 and the fixed bracket 90 and a second rotating shaft 120 for connecting the ground pin 25 and the support frame 30. In addition, the ground conductive copper sheet 143, the ground wire 180, the ground copper sleeve 133 and the third storage slot 123 for storing the ground pin 25 are also reduced. However, the principle of folding and unfolding the outer shell 10 is the same in both embodiments.

[0060] It should be noted that 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 scope of protection of this application.
