Description

Technical Field

[0001] This application relates to the technical field of power socket accessories, and in particular to a power socket with a USB interface. Background Technology

[0002] In today's rapidly developing technological world, electronic devices have become deeply integrated into people's daily lives, serving as indispensable partners for work, entertainment, and study. Traditional power sockets can only meet the needs of plugging in ordinary power cords, but with the widespread use of USB charging devices, a single charging interface can no longer meet the diverse power usage scenarios. Against this backdrop, power sockets with USB interfaces have emerged, which can simultaneously accommodate USB data cables and ordinary power cords, providing great convenience for people using electronic devices.

[0003] In related technologies, a power socket includes a housing, a cover detachably mounted on the housing, and an electrical component located inside the housing. The electrical component includes several socket cores and terminals. The outer surface of the cover has several socket holes for connecting ordinary power plugs and USB connectors for connecting USB data cables. Different socket cores correspond to the socket holes and USB connectors, respectively. The terminals are used to connect power cords to the socket cores, transmitting power from the power cords to the socket cores, thereby powering the connected devices.

[0004] In the aforementioned technologies, when power sockets are installed on factory walls, screws are typically used for fixing. The screws are passed through the pre-drilled holes in the casing and then screwed into the holes in the wall. However, factory environments are complex, and equipment heights vary, resulting in different plug and cable lengths. Sometimes, the equipment plug cannot reach the socket because the cable is too short. Since the equipment is heavy and difficult to move, the socket can only be moved. However, the screws are tightly attached to the wall, and the screws are small. Workers need to use special tools to disassemble them, making the process cumbersome and time-consuming, which seriously affects work efficiency and leaves room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a power socket with a USB interface, which solves the problem of cumbersome and time-consuming screw removal when the socket needs to be moved in the above-mentioned related technologies.

[0006] The power socket with a USB interface provided in this application adopts the following technical solution:

[0007] A power socket with a USB interface includes a housing, a cover detachably mounted on the housing, and electrical components located inside the housing. The outer surface of the cover has several first sockets for connecting a standard power plug and several second sockets for connecting a USB data cable. The housing has a base plate fixedly mounted on a wall. Two symmetrical guide protrusions are fixedly mounted on the outer periphery of the cover near the base plate. Two limiting strips are fixedly mounted side-by-side on the base plate in a vertical direction. Limiting grooves are formed on the sides of the two limiting strips that are close to each other, allowing the guide protrusions to be inserted and slid. A height-adjustable support plate is located below the housing. Several support blocks are fixedly mounted on the side of the support plate near the base plate. Several locking grooves are evenly formed on the base plate in a vertical direction for the support blocks to be inserted. The support plate supports the lower side of the housing after the support blocks are inserted into the locking grooves.

[0008] By adopting the above technical solution, when factory equipment has varying heights, resulting in different plug and cable lengths, and situations arise where the equipment plug cannot reach the socket due to the cable being too short, there is no need to painstakingly remove screws fixed to the wall with tools to move the socket as in the traditional method. Simply slide the housing along the limiting groove to easily adjust the socket's vertical position, bringing it closer to the equipment plug. At the same time, according to the adjusted position, insert the support block of the support plate into the corresponding height locking groove, and the support plate will firmly support the lower side of the housing, ensuring the stability of the socket installation. The operation is convenient and efficient, greatly improving the flexibility and convenience of socket use in factory and other scenarios.

[0009] Optionally, the side edge of the support block away from the base plate is a guide slope.

[0010] By adopting the above technical solution, the guide slope can guide the support block into the locking groove during the process of inserting the support block into the groove, making the support block enter the groove more smoothly and reducing the difficulty of insertion. Even if the operator's force direction is slightly off, the insertion action can be completed smoothly with the help of the guide slope, thus improving the installation efficiency.

[0011] Optionally, the limiting groove is fixed with an elastic element that limits the sliding state of the guide protrusion, and the outer peripheral surface of the housing is provided with a plurality of positioning grooves corresponding to the locking groove; the elastic element can be inserted into and removed from the positioning groove during the sliding process of the housing, and the support plate supports the lower side of the housing when the elastic element is inserted into the positioning groove.

[0012] By adopting the above technical solution, when the housing is pushed to slide along the limiting groove, the elastic element inside the limiting groove will sequentially contact the positioning groove on the housing as the housing moves. When the elastic element engages with the positioning groove, a distinct locking sensation is generated. This feedback allows the user to accurately perceive the socket's positioning position, facilitating adjustment to the ideal height.

[0013] Optionally, the inner wall of the limiting groove is provided with an installation cavity for inserting an elastic element. The elastic element includes a spring and a positioning protrusion. One end of the spring presses one side of the positioning protrusion so that a part of the positioning protrusion protrudes out of the opening of the installation cavity. The protruding part of the positioning protrusion is an arc surface, and the arc length corresponding to the arc surface of the protruding part is a minor arc.

[0014] By adopting the above technical solution, when the housing is pushed to slide, the inferior arc surface of the positioning protrusion contacts the positioning groove. The inferior arc design makes the contact surface transition naturally. During the sliding process, it can reduce frictional resistance, allowing the user to easily push the housing, and also produce clear and appropriate sticking feedback.

[0015] Optionally, a rotating plate is provided on the upper side of the base plate above the housing, and one side of the rotating plate is rotatably connected to the upper side of the base plate; the rotating plate can rotate to two states, vertically upward and horizontal, and then be fixed; when the rotating plate is in the horizontal state, a storage groove is provided on the bottom surface, and a protective curtain is provided on the outside of the base plate, with one edge of the protective curtain fixedly connected to the inner wall of the storage groove; when the rotating plate is in the horizontal state, the protective curtain can be unfolded downward from the storage groove to protect the outside of the housing.

[0016] By adopting the above technical solution, when the protective curtain is not in use, the rotating plate stands upright, without occupying extra space and maintaining an overall clean look; when protection is needed, the rotating plate is turned to a horizontal position, at which point the protective curtain in the storage slot can be unfolded downwards to cover the outside of the casing, effectively preventing dust, water stains, etc. from entering the socket, avoiding damage to the socket or causing safety hazards due to environmental factors, and extending the service life of the socket.

[0017] Optionally, an arc-shaped cover plate is fixed on the edge of the protective curtain away from the rotating plate; when the protective curtain is placed into the storage slot, the arc-shaped cover plate can be detachably installed at the opening edge of the storage slot; when the protective curtain is unfolded in a vertically downward direction, the arc-shaped cover plate drives the protective curtain to unfold vertically downward.

[0018] By adopting the above technical solution, an arc-shaped cover plate is set on the protective curtain. When it is stored in the storage slot, it can be detachably installed at the edge of the opening of the storage slot. This design makes the protective curtain stable in the stored state and will not accidentally slip out due to slight external touch, thus ensuring the neatness of the storage. When the protective curtain needs to be used, the arc-shaped cover plate plays a key role. As it moves downward, it can drive the protective curtain to unfold vertically and smoothly in the vertical direction, so that the protective curtain can accurately and completely cover the shell and form an effective protective barrier.

[0019] Optionally, a plurality of fixing blocks are fixedly provided on the rotating plate, and a plurality of positioning blocks are fixedly provided on the outer peripheral surface of the arc-shaped cover plate near the rotating plate. The positioning blocks are provided with fixing grooves for the fixing blocks to be inserted into; the fixing blocks can be inserted into the fixing grooves when the protective curtain is placed into the storage slot.

[0020] By adopting the above technical solution, when the protective curtain is placed into the storage slot, the fixing block is precisely inserted into the fixing groove. This locking structure can firmly fix the protective curtain in the storage slot, effectively preventing the protective curtain from falling out on its own due to external vibration, shaking or accidental touch, and ensuring the stability of the storage state.

[0021] Optionally, a pull ring is fixed on the outer peripheral surface of the arc-shaped cover plate away from the fixing block.

[0022] By adopting the above technical solution, when the protective curtain stored in the storage slot needs to be unfolded, the user only needs to hold the pull ring and pull it down to easily drive the arc-shaped cover and the protective curtain to unfold vertically in the vertical direction, without having to painstakingly find the position of the arc-shaped cover or use other complicated operations.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When factory equipment has varying heights, resulting in different plug and cable lengths, and situations arise where the equipment plug cannot reach the socket due to the cable being too short, there is no need to painstakingly remove the screws fixed to the wall with tools to move the socket as in the traditional method. Simply slide the housing along the limiting groove to easily adjust the socket's vertical position and bring it closer to the equipment plug. At the same time, according to the adjusted position, insert the support block of the support plate into the corresponding height locking groove. The support plate will then firmly support the lower side of the housing, ensuring the stability of the socket installation. The operation is convenient and efficient, greatly improving the flexibility and convenience of socket use in factory and other scenarios.

[0025] 2. When the protective curtain is not in use, the rotating plate stands upright, taking up no extra space and maintaining an overall clean look. When protection is needed, the rotating plate is turned to a horizontal position, at which point the protective curtain in the storage slot can be unfolded downwards to cover the outside of the casing, effectively preventing dust, water stains, etc. from entering the socket, avoiding damage to the socket or causing safety hazards due to environmental factors, and extending the service life of the socket.

[0036] The present application will be further described in detail below with reference to all the accompanying drawings.

[0037] Example:

[0038] Reference Figure 1 A power socket with a USB interface includes a housing 1, a cover 11 removably mounted on the housing 1, and an electrical component 12 located inside the housing 1 (see...). Figure 5 The outer side of the cover 11 has several first sockets 13 for connecting a common power plug and second sockets 14 for connecting a USB data cable.

[0039] In everyday use, when users need to charge electrical devices with standard plugs, they can simply insert the plug into the first socket 13 to easily transfer power and quickly restore the device's charge. If they need to charge electronic devices with USB interfaces such as mobile phones and tablets, there is no need to find an adapter. They can simply insert the USB data cable into the second socket 14 to quickly establish a charging connection. The operation is simple and efficient.

[0040] Reference Figure 2 , Figure 3 and Figure 4 The shell 1 has a base plate 2 located on the wall along the vertical direction. The outer periphery of the shell cover 11 has two symmetrical guide protrusions 111 integrally injection molded. The base plate 2 has two limiting strips 21 installed by welding. The limiting strips 21 are installed side by side along the vertical direction on the base plate 2. The two limiting strips 21 have limiting grooves 211 on their sides that are close to each other, allowing the guide protrusions 111 to be inserted and slide.

[0041] A support plate 3 is provided on the base plate 2, located below the housing 1. Two support blocks 31 are integrally formed on the side of the support plate 3 near the base plate 2. The side edge of the support block away from the base plate is a guide slope 311. Several locking grooves 22 are evenly opened on the base plate 2 in the vertical direction for the support blocks 31 to be inserted. The support plate 3 can support the lower side of the housing 1 after the support blocks 31 are inserted into the locking grooves 22.

[0042] Both the housing 1 and the cover 11 are made of plastic. When the installation position of the socket needs to be changed, the user can push the housing 1 so that it slides in the limiting groove 211 of the base plate 2 through the guide protrusion 111 to adjust the position. At the same time, the support plate 3 can also flexibly change the installation point according to the new installation position to continue to provide effective support for the housing 1 and prevent it from falling.

[0043] Reference Figure 5 and Figure 6 An elastic element 4 is fixedly installed inside the limiting groove 211 to limit the sliding state of the guide protrusion 111, and several locking grooves 22 are formed on the outer peripheral surface of the guide protrusion 111 (see...). Figure 4 The corresponding positioning groove 1111;

[0044] The inner wall of the limiting slide groove 211 is provided with an installation cavity 2111 for the elastic element 4 to be inserted. The elastic element 4 includes a spring 41 and a positioning protrusion 42. One end of the spring 41 presses one side of the positioning protrusion 42 so that a part of the positioning protrusion 42 protrudes out of the opening of the installation cavity 2111. The protruding part of the positioning protrusion 42 is an arc surface, and the arc length corresponding to the arc surface of the protruding part is a minor arc.

[0045] During the sliding process, the positioning protrusion 42 will sequentially contact each positioning groove 1111 as the housing 1 moves; when the positioning protrusion 42 is engaged in the positioning groove 1111, a certain locking sensation will be generated. This locking sensation can ensure precise engagement and positioning. Moreover, the arc-shaped design allows the positioning protrusion 42 to be disengaged from the positioning groove 1111 with only slight force when it contacts the positioning groove 1111, so the position of the housing 1 can be changed at any time; support plate 3 (see Figure 4 When the positioning protrusion 42 is engaged in the positioning groove 1111, it can support the lower side of the housing 1. The two work together to achieve both sliding and limiting.

[0046] Reference Figure 7 and Figure 8 The housing 1 is provided with a rotating plate 5 located on the upper side of the base plate 2, and one side of the rotating plate 5 is rotatably connected to the upper side of the base plate 2; wherein when the rotating plate 5 is rotated to the vertical upward state, it can be fixed to the wall with bolts, and when the rotating plate 5 is rotated to the horizontal state, it can abut against the side of the limiting strip 21.

[0047] When the rotating plate 5 is in a horizontal state, a storage groove 51 is provided on the bottom surface. A protective curtain 52 is provided on the outside of the bottom plate 2. One side edge of the protective curtain 52 is fixedly connected to the inner wall of the storage groove 51. After the user rotates the rotating plate 5 to a horizontal state, the protective curtain 52 can be taken out from the storage groove 51 and unfolded downwards. At this time, the outer surface of the shell 1 can be protected to prevent dust and other impurities from entering the shell 1 from the first socket 13 and the second socket 14.

[0048] Reference Figure 7 and Figure 8 An arc-shaped cover plate 53 is fixedly installed on the edge of the protective curtain 52 away from the rotating plate 5, and a pull ring 531 is fixedly installed on the side of the arc-shaped cover plate 53 away from the rotating plate 5. In daily use, the user can use the pull ring 531 to drive the arc-shaped cover plate 53 to insert the protective curtain 52 into the storage slot 51. At this time, the arc-shaped cover plate 53 can block the opening of the storage slot 51. When the protective curtain 52 is unfolded in a vertically downward direction, due to the gravity of the arc-shaped cover plate 53, the user can use the pull ring 531 to drive the protective curtain 52 to quickly unfold vertically downward.

[0049] Reference Figure 7 and Figure 8Several fixing blocks 54 are fixedly installed on the rotating plate 5; two positioning blocks 532 are integrally formed on the outer circumference of the arc-shaped cover plate 53, and the positioning blocks 532 are provided with fixing grooves 5321 for the fixing blocks 54 to be inserted; when the protective curtain 52 needs to be stored, the pull ring 531 drives the arc-shaped cover plate 53 to place the protective curtain 52 into the storage groove 51, and the fixing blocks 54 can be inserted into the fixing grooves 5321. At this time, the arc-shaped cover plate 53 can prevent external dust and other impurities from entering the storage groove 51.

[0050] The implementation principle of this application embodiment is as follows:

[0051] When the user needs to adjust the position of the socket, simply push the housing 1 gently, and the guide protrusion 111 will slide smoothly along the limiting groove 211 on the base plate 2. During this process, the positioning protrusion 42 of the elastic element 4 moves with the housing 1 and makes precise contact with the positioning groove 1111 in sequence. When it is engaged, it will bring a clear sense of engagement and achieve precise positioning. Its unique arc design also allows the positioning protrusion 42 to easily disengage from the positioning groove 1111, making it convenient to change the position at any time. At the same time, the support plate 3 can flexibly change the installation point according to the new position to provide stable support for the socket.

[0052] When the socket is not in use, the user can rotate the rotating plate 5 to a horizontal position. The pull ring 531 will drive the arc-shaped cover plate 53 to unfold the protective curtain 52 from the storage slot 51, which can prevent dust and other impurities from entering the first socket 13 and the second socket 14. When the protective curtain 52 needs to be stored, the user can use the pull ring 531 to drive the arc-shaped cover plate 53 to insert the protective curtain 52 into the storage slot 51. At this time, when the fixing block 54 is inserted into the fixing groove 5321, the protective curtain 52 can be further secured. When the rotating plate 5 is rotated to a vertical position, it can also be fixed to the wall with bolts, saving space.
