Description

Technical Field

[0001] This invention relates to the field of electrical connection device technology, and in particular to an embedded socket with a bidirectional flip cover and adjustable depth. Background Technology

[0002] Recessed sockets are widely used in modern office desks, conference tables, bedside tables, cabinets, and other furniture due to their neat appearance, space-saving design, and ease of integration. These sockets typically require mounting holes to be made in the desktop or panel to embed the socket body, and a hinged cover is installed on the surface to conceal the socket when not in use, achieving dust prevention, safety, and aesthetics.

[0003] With the diversification of usage scenarios and the improvement of user needs, traditional recessed sockets have gradually shown the following two shortcomings in terms of structural design and function:

[0004] Firstly, regarding cover design, early products mostly featured a unidirectional flip-up structure, facilitating operation only for users on one side. To meet the needs of central desktop installation for use by users on both sides, receptacles capable of bidirectional flip-up opening have emerged on the market. However, existing bidirectional flip-up cover technology often faces a dilemma: some products employ complex bidirectional hinges or pivot mechanisms, resulting in numerous components, high costs, complex assembly, and poor long-term reliability; other designs, while allowing the cover to flip freely to both sides, lack an effective damping control mechanism, leading to abrupt and excessively fast opening or closing movements, easily generating impact noise, and posing a potential risk of pinching users' fingers. A few products that attempt to integrate damping functions often have bulky structures or struggle to provide continuous and uniform damping force in both forward and backward flipping directions, resulting in uneven cover movement and a poor user experience.

[0005] Secondly, regarding the installation and compatibility of the socket itself, the installation cavity depth of existing recessed sockets is mostly a fixed design. With the diversification of electronic devices, the size and shape of their power adapters or plugs vary greatly. A fixed installation depth makes it difficult to accommodate all plugs: when the cavity is too deep, smaller plugs are difficult to remove after insertion, and excessive exposure of some plug metal prongs poses a safety hazard; when the cavity is too shallow, larger plugs may protrude from the opening surface, preventing the cover from closing completely, affecting aesthetics and compromising dustproof function. Patent CN207398772U discloses a cable management box for a conference table, but its box has a fixed depth, which also fails to solve the aforementioned compatibility problem.

[0006] In summary, existing embedded sockets still need a comprehensive solution that is simple in structure, reliable, and cost-controllable in addressing two core user experience issues: how to achieve smooth, quiet, and safe bidirectional flipping of the cover, and how to flexibly adjust the socket installation depth to accommodate plugs of different sizes. Summary of the Invention

[0007] To address the aforementioned problems, the present invention aims to provide an embedded socket that simultaneously solves the following two key issues:

[0008] 1. Damping control problem of bidirectional flip cover: Solve the problem that existing bidirectional flip covers lack effective damping when opening or closing, resulting in abrupt action, high noise, risk of pinching injury, and some damping structures are complex, bulky, or have uneven bidirectional damping.

[0009] 2. The problem of non-adjustable socket installation depth: Solve the limitation that the existing recessed socket has a fixed inner cavity depth, which makes it difficult to adapt to power plugs of different sizes, and easily leads to inconvenience in plugging or the cover not being able to close.

[0018] Preferably, inside the top opening of the main frame, at the front and rear edges of the cover plate when it is closed, brush assemblies are respectively provided; the brush assemblies are used to provide operating space for fingers to insert and operate the cover plate and to prevent dust.

[0019] Preferably, the base support is constructed as a "U"-shaped support or a "V"-shaped support, and has two installation states: forward and reverse. When installed forward, the opening of the base support faces upward and can slide and be positioned longitudinally along the main frame. When installed in reverse, the opening of the base support faces downward.

[0020] Preferably, the main frame includes side supports disposed on opposite sides, and the two side supports extend downwards to form legs, and the base support can be installed on the legs in either the forward or reverse installation state.

[0028] Compared with the prior art, the present invention has the following significant advantages:

[0029] 1. Achieves a superior bi-directional flipping operation experience: Through the coordinated work of the left and right sides and the installation of flipping adjustment modules facing opposite directions, combined with damping gears and linkage transmission, the cover plate ensures uniform, smooth, and adjustable damping force in both flipping directions and throughout the entire opening and closing process. This design effectively eliminates impact noise and the risk of pinching fingers, greatly improving operational safety, comfort, and product quality.

[0030] 2. It possesses powerful and flexible depth adjustment capabilities: By switching the "positive / negative" installation orientation of the base bracket, and combining it with the adjustable rack (or groove) to achieve stepless / stepped sliding positioning in the longitudinal direction, users can conveniently and precisely adjust the effective depth of the socket cavity according to different plug sizes. This fundamentally solves the common problems of fixed-depth sockets where "the plug protrudes and the cover cannot be closed" or "the cavity is too deep, making insertion and removal inconvenient," significantly expanding the product's versatility and practicality.

[0031] 3. Achieving a highly integrated and reliable structural design: The complex bidirectional damping tilting mechanism and multi-mode depth adjustment mechanism are cleverly integrated into a compact main frame. The tilting module is symmetrical and modular, and the adjustment mechanism is easy to operate and reliably locked. The overall structure achieves complex high-end functions while ensuring ease of production, reliable assembly, and good cost control.

[0032] 4. Enhanced functional details and usage scenarios: The brush assembly design balances dust prevention and ease of operation; the bottom power outlet provides an additional power source; and the modular design of the base bracket facilitates the installation and replacement of the socket itself. These details enable this product to better meet the high standards of aesthetics, safety, convenience, and flexibility required in various scenarios such as offices, meetings, and homes.

[0051] like Figure 1-5 As shown, this embodiment proposes an embedded socket with a bidirectional flip cover and adjustable depth, including a main frame 1 for embedding in a table hole in a tabletop. The top of the main frame 1 is provided with a top frame 102 with a top opening 10. A cover 19, which can be flipped open bidirectionally forward and backward, is rotatably disposed in the top opening 10. A flip adjustment module is provided on the left and right sides inside the top opening 10. Each flip adjustment module includes a damper disposed on the main frame 1 and a transmission component connected between the damper and the cover 19. The flip adjustment modules on both sides are configured such that when the cover plate 19 flips forward, the transmission component on one side rotates with the cover plate 19 and drives the damper on that side to provide resistance, while the transmission component on the other side rotates relative to the cover plate 19; when the cover plate 19 flips backward, the above-mentioned driving and relative rotation relationship between the transmission components on both sides and the cover plate 19 is reversed, so that the flip damping of the cover plate 19 is always provided by the flip adjustment module on one side, whether it flips forward or backward.

[0052] For ease of understanding, the following explains some key terms in this embodiment:

[0053] The main frame 1 is designed to be fitted into the table hole in the tabletop, providing structural support and fixation for the entire embedded socket.

[0054] The top frame 102 is located on top of the main frame 1 and has a top opening 10 that provides space for the installation and flipping of the cover plate 19.

[0055] The cover 19 is rotatably disposed in the top opening 10 and can be flipped open in both directions, forward and backward, to cover or expose the interior of the socket.

[0056] The flip adjustment module is the core mechanism for realizing the bidirectional flip damping of the cover plate 19. Each module contains a damper and a transmission component.

[0057] A damper, which is disposed on the main frame 1, is used to provide controlled resistance during the flipping of the cover plate 19 to slow down the flipping speed.

[0058] The transmission component, which is connected between the damper and the cover plate 19, is responsible for transmitting the flipping motion of the cover plate 19 to the damper, or allowing relative rotation under certain conditions.

[0059] Specifically, the embedded socket in this embodiment includes a main frame 1, which is used to be embedded in a table hole in a tabletop. A top frame 102 with a top opening 10 is provided on the top of the main frame 1. A cover plate 19 is rotatably disposed in the top opening 10 and can be flipped open in both forward and backward directions. Further, a flip adjustment module is provided on the left and right sides inside the top opening 10. These flip adjustment modules can be respectively installed on the inner walls of the left and right sides of the top opening 10, for example, by fixing the base of the module to the inner wall of the top frame 102 with screws. Each flip adjustment module includes a damper disposed on the main frame 1 and a transmission component connecting the damper and the cover plate 19. The damper can be a friction damper, providing resistance through the contact between a friction plate and a rotating shaft. It can also be a pneumatic damper, generating resistance through the movement of a piston within a cylinder. The damper can be directly fixed to the inner wall of the main frame 1. The transmission component can be a connecting rod, with one end connected to the damper and the other end connected to the cover plate 19.

[0060] The flip adjustment modules on both sides are configured such that when the cover plate 19 flips forward, the transmission component on one side rotates with the cover plate 19 and drives the damper on that side to provide resistance, while the transmission component on the other side rotates relative to the cover plate 19; when the cover plate 19 flips backward, the above-mentioned driving and relative rotation relationship between the transmission components on both sides and the cover plate 19 is reversed, so that the flip damping of the cover plate 19 is always provided by the flip adjustment module on one side, whether it flips forward or backward.

[0061] Therefore, the embedded socket with a bidirectional flip cover of this application, by setting flip adjustment modules on the left and right sides inside the top opening 10 and configuring their driving and relative rotation relationships, ensures that the flip damping of the cover 19 is always provided by the flip adjustment module on one side, regardless of whether it flips forward or backward. This design solves the problems of complex structure and lack of effective damping in existing bidirectional flip covers, avoids the lack of smoothness in the opening or closing action of the cover, the generation of impact noise, and the risk of pinching fingers, while taking into account production costs and assembly convenience, providing users with a smooth and controlled operating experience.

[0062] In the specific implementation plan, the tilt adjustment modules on both sides have identical structures, but their installation orientation on the main frame 1 is opposite in the front-to-back direction. Specifically, "the tilt adjustment modules on both sides have identical structures" means that all components constituting the left and right tilt adjustment modules, including dampers, transmission components, and their connection methods, are completely identical in design, size, materials, and function. For example, a standardized, modular design can be adopted, making all parts interchangeable, with the dampers and transmission components on both sides produced from the same batch and having the same specifications and performance. Alternatively, the internal structure, external dimensions, and connection interface with the main frame 1 of the module are consistent, with orientation adjustment only required during installation. This design effectively simplifies the production process, reduces the number of parts, and decreases inventory, thereby improving production efficiency and product consistency.

[0063] Meanwhile, the phrase "the two modules are installed in opposite directions on the main frame 1" means that although the two modules themselves have the same structure, when installed on the main frame 1, their internal driving or damping directions relative to the flipping axis of the cover plate 19 or the front-back direction of the main frame 1 are opposite. For example, if one module provides damping when the cover plate 19 flips forward, then the other module with the same structure has its damping direction reversed during installation, so that it provides damping when the cover plate 19 flips backward. This can be achieved through the symmetrical design of the module itself, or by rotating it 180 degrees during installation. Alternatively, it can be assumed that there is a one-way mechanism inside the module. By installing the two modules in a mirror-symmetrical manner, it can be ensured that when the cover plate 19 flips in one direction, the one-way mechanism of one module is activated, and when the cover plate 19 flips in the other direction, the one-way mechanism of the other module is activated.

[0064] Through the above technical solution, since the flip adjustment modules on both sides have the same structure, the manufacturing and assembly process of the product is greatly simplified, production costs are reduced, and the demand for component diversity is decreased, thereby improving production efficiency and product consistency. Simultaneously, by configuring these two structurally identical modules on the main frame 1 with opposite mounting orientations, it is ensured that regardless of whether the cover 19 flips forward or backward, stable and consistent flipping damping can be provided by one side's flip adjustment module. While maintaining the bidirectional flipping damping effect of the cover 19, the reliability and long-term stability of the system are significantly improved, providing users with a smooth and controlled opening and closing experience, effectively avoiding impact noise and potential pinching risks caused by the cover 19's abrupt movements and excessive speed. Overall, this application optimizes the structural design while ensuring functionality, achieving a balance between cost-effectiveness and user experience.

[0065] In the specific embodiment shown, the damper is a damping gear 203, and the transmission component is a connecting rod 204. The first end of the connecting rod 204 is provided with an arc-shaped toothed plate 221, which meshes with the damping gear 203. The second end of the connecting rod 204 is movably hinged to the cover plate 19. Specifically, the damping gear 203 is a gear mechanism capable of providing rotational resistance. It typically contains a damping medium, such as high-viscosity silicone oil or special grease. The rotation of the gear drives the medium to flow or rub, thereby generating a stable damping force. The damping gear 203 can adopt various structural forms; for example, it can be a sealed gearbox filled with damping fluid. The damping gear 203 is a gear specifically designed to produce a damping effect, its core being the dissipation of energy through the viscosity of the internal fluid, thereby providing smooth motion resistance. This damping gear 203 can be designed as a sealed cavity precisely filled with a damping fluid with specific viscosity characteristics. When the gears rotate, the damping fluid inside the cavity experiences shearing action, generating resistance related to the rotational speed, thereby effectively controlling the movement of the cover plate 19. This design ensures smooth and controllable resistance during the flipping of the cover plate 19, preventing the cover plate 19 from moving too quickly or too sharply. Alternatively, the damping gear 203 can consist of multiple meshing gears, with at least one gear or its mating cavity filled with damping fluid. Resistance is generated through the relative motion between the gears and the viscosity of the damping fluid. Furthermore, a planetary gear structure can be used, immersing planetary gears or a sun gear in damping fluid, utilizing the relative motion between the gears and the viscosity of the damping fluid to provide the required damping force. All these designs aim to ensure that the damping force is uniform and controllable during gear rotation.

[0066] The connecting rod 204, as a transmission component, primarily functions to transmit the flipping motion of the cover plate 19 to the damping gear 203 and, in the opposite direction, to transmit damping force. The connecting rod 204 is typically a rod-shaped member with a certain rigidity, with connecting structures designed at both ends. The connecting rod 204 can be made of metal materials such as steel or aluminum alloy to ensure sufficient strength and rigidity; it can also be made of high-strength engineering plastics to achieve lightweighting and cost reduction. Its specific shape and dimensions can be optimized according to the internal space of the socket and transmission requirements. The first end of the connecting rod 204 is provided with an arc-shaped toothed plate 221. The arc-shaped toothed plate 221 is a key structure at the first end of the connecting rod 204, having an arc-shaped profile and teeth along the arc. This arc-shaped toothed plate 221 matches the tooth profile of the damping gear 203, forming a meshing transmission relationship. The arc-shaped toothed plate 221 can be an integrally formed structure on the connecting rod 204, or it can be a separately manufactured component fixed to the end of the connecting rod 204. Its tooth design must ensure that the arc-shaped toothed plate 221 and the damping gear 203 maintain a smooth and reliable meshing throughout the entire flipping stroke of the cover plate 19, thereby effectively converting the rotation of the cover plate 19 into the rotation of the damping gear 203 and transmitting the damping force.

[0067] The second end of the connecting rod 204 is movably hinged to the cover plate 19. This movable hinge means that the two are connected through a rotatable connection point, allowing the connecting rod 204 to rotate freely relative to the cover plate 19 within a certain angle range. For example, the hinge can be achieved by a pin passing through a hole at the end of the connecting rod 204 and a corresponding connecting seat on the cover plate 19; or a ball joint hinge or other structure can be used to provide more flexible rotational freedom. This movable hinge is key to achieving bidirectional tilting damping. It allows the connecting rod 204 on one side to drive the damping gear 203 when the cover plate 19 tilts in one direction, while the connecting rod 204 on the other side can rotate relative to the cover plate 19 without driving its damping gear 203, thus ensuring that damping is provided only by the tilting adjustment module on one side.

[0068] Through the above technical solution, the damper is specifically defined as a damping gear 203, and the transmission component is specifically defined as a connecting rod 204. The first end of the connecting rod 204 is designed to have an arc-shaped toothed plate 221 that meshes with the damping gear 203, and the second end of the connecting rod 204 is movably hinged to the cover plate 19. This application effectively solves the problems of unstable damping effect, complex structure, and increased assembly difficulty. Specifically, the damping gear 203, as a damper, provides uniform and controllable rotational damping through its gear structure, ensuring smooth and stable operation of the cover plate 19 during opening and closing, avoiding noise and potential pinching risks caused by abrupt movements. The connecting rod 204, as a transmission component, achieves efficient and reliable transmission between the movement of the cover plate 19 and the action of the damper through the precise meshing of its arc-shaped toothed plate 221 with the damping gear 203. More importantly, the hinged design of the second end of the connecting rod 204 and the cover plate 19 cleverly complements the bidirectional flipping characteristics of the cover plate 19. When the cover plate 19 flips forward, one side of the connecting rod 204 rotates with the cover plate 19, driving the damping gear 203 on that side to provide resistance, while the other side's connecting rod 204 rotates relative to the cover plate 19 without driving its damping gear 203. When the cover plate 19 flips backward, the driving and relative rotation relationships between the two connecting rods 204 and the cover plate 19 are reversed. This mechanism ensures that the cover plate 19 always receives smooth flipping damping from the flipping adjustment module on one side, regardless of whether it flips forward or backward. This simplifies the overall mechanism design, reduces manufacturing costs and assembly difficulty, and significantly improves user experience and product reliability.

[0069] Furthermore, this application proposes that the damping gear 203 is configured to provide damping force during both the opening and closing of the cover plate 19. The internal damping mechanism of the damping gear 203 can be designed to generate damping force during both forward and reverse rotation. The meshing relationship between the damping gear 203 and the arc-shaped toothed plate 221 of the connecting rod 204 can also be designed to maintain effective contact and transmit damping force throughout the entire opening and closing stroke of the cover plate 19. This means that the tooth profile and length of the arc-shaped toothed plate 221 are sufficient to cover all the meshing angles required by the damping gear 203 during the movement of the cover plate 19, ensuring the continuity of the damping effect. Through the above technical solution, the damping gear 203 can continuously apply damping force to the movement of the cover plate 19, regardless of whether the cover plate 19 is in the open or closed state. When the user opens the cover 19, the damping gear 203 provides smooth resistance to prevent the cover 19 from popping open quickly. When the user closes the cover 19, the damping gear 203 also provides resistance, effectively slowing down the closing speed of the cover 19, avoiding the impact noise caused by the cover 19 closing quickly due to gravity or inertia, and significantly reducing the risk of pinching fingers. Combined with the configuration of the two-sided flip adjustment module in the above solution, that is, regardless of whether the cover 19 flips forward or backward, the flip damping is always provided by one side of the flip adjustment module. This application ensures that a uniform and controlled damping effect can be obtained in any flipping direction (forward or backward) and any movement stage (opening or closing) of the cover 19, greatly improving the smoothness, safety and comfort of the user experience.

[0070] like Figure 2-4 As shown, this application further proposes a cover 20 fixed to the side wall of the top opening 10, with the damping gear 203 housed inside the cover 20; the upper end of the cover 20 is provided with an opening 202 and a hinge seat 201 located next to the opening 202, the first end of the connecting rod 204 is rotatably connected to the hinge seat 201, and the arc-shaped toothed plate 221 passes through the opening 202 and meshes with the damping gear 203; when the cover plate 19 is opened to the maximum angle, a portion of the arc-shaped toothed plate 221 rotates out of the opening 202 along with the connecting rod 204.

[0071] Specifically, the enclosure 20 is a structural component used to cover or enclose internal parts. Its concept is to provide a physical barrier to protect sensitive internal components from external environmental factors such as dust, liquids, and mechanical impacts. The enclosure 20 can be made of various materials, such as engineering plastics, metal alloys, or composite materials, depending on factors such as required strength, wear resistance, corrosion resistance, and cost. Its shape and size are typically designed according to the components to be protected and their range of motion to ensure adequate protection and structural compactness. The damping gear 203 is housed within the enclosure 20 to effectively isolate and protect it. This configuration prevents external dust, debris, or other contaminants from entering the meshing area of ​​the damping gear 203 or the internal damping fluid, thereby avoiding accelerated wear, decreased damping performance, or mechanical jamming caused by contamination. Simultaneously, the enclosure 20 also provides a degree of mechanical protection for the damping gear 203, reducing the risk of damage from external impacts or accidental contact.

[0072] An opening 202 is provided at the upper end of the cover 20 to allow the arc-shaped toothed plate 221 on the connecting rod 204 to pass through and mesh with the internal damping gear 203, thereby transmitting motion and damping force. The shape and size of the opening 202 need to be precisely designed to minimize the opening area while ensuring smooth movement of the arc-shaped toothed plate 221, thus maintaining the protective function of the cover 20. The hinge seat 201 located next to the opening 202 is a structure that provides rotational support. It usually has a shaft hole or bearing inside so that the first end of the connecting rod 204 can be stably and with low friction rotated. The setting of the hinge seat 201 ensures the accuracy and stability of the movement of the connecting rod 204. The rotational connection between the first end of the connecting rod 204 and the hinge seat 201 is the key to realizing the swinging motion of the connecting rod 204. This connection method allows the connecting rod 204 to rotate within a limited angle around the hinge seat 201, thereby converting the flipping motion of the cover plate 19 into the oscillation of the arc-shaped toothed plate 221, which in turn drives the damping gear 203. The rotating connection can be achieved through various methods such as pins, bolts and bushings, or integrated shafts, aiming to ensure smooth movement, reliability, and low frictional loss. The arc-shaped toothed plate 221, passing through the opening 202 of the cover 20, meshes with the damping gear 203, and is the core link in the transmission of damping force. The tooth profile of the arc-shaped toothed plate 221 matches the tooth profile of the damping gear 203, ensuring that the damping gear 203 can be driven to rotate smoothly and continuously when the connecting rod 204 oscillates. This meshing relationship transmits the flipping torque of the cover plate 19 to the damping gear 203 through the connecting rod 204 and the arc-shaped toothed plate 221. The damping gear 203 provides controlled damping force, thereby achieving the smooth opening or closing of the cover plate 19.

[0073] Furthermore, when the cover 19 is opened to its maximum angle, a portion of the arc-shaped toothed plate 221 rotates out of the opening 202 along with the connecting rod 204. This technical feature aims to optimize the range of motion of the mechanism and avoid interference. When the cover 19 is fully opened to its maximum tilting angle, the connecting rod 204 swings to its limit position. At this time, a portion of the arc-shaped toothed plate 221 rotates out of the opening 202 of the cover 20, meaning it is no longer completely inside the opening 202. This design ensures that when the cover 19 reaches its maximum opening angle, the arc-shaped toothed plate 221 will not jam or collide with the edge of the opening 202, thereby ensuring the smooth tilting motion of the cover 19 and preventing damage to the mechanism.

[0074] Through the above technical solution, a cover 20 fixed to the side wall of the top opening 10 is introduced, and the damping gear 203 is housed inside it, effectively solving the problems of dust pollution and mechanical damage caused by the damping gear 203 being exposed to the outside. The cover 20 provides a closed and protected environment for the damping gear 203, significantly reducing the risk of external contaminants entering the damping mechanism, thereby extending the service life of the damping gear 203 and ensuring its long-term stable damping performance. The design of the opening 202 and hinge seat 201 at the upper end of the cover 20, and the first end of the connecting rod 204 rotatably connected to the hinge seat 201, allows the arc-shaped toothed plate 221 to accurately pass through the opening 202 and mesh with the damping gear 203, realizing the effective linkage between the flipping movement of the cover plate 19 and the rotation of the damping gear 203. This structure provides protection while maintaining the normal function of the damping mechanism. Furthermore, when the cover 19 is opened to its maximum angle, a section of the arc-shaped toothed plate 221 rotates out of the opening 202 along with the connecting rod 204. This cleverly avoids interference between the arc-shaped toothed plate 221 and the edge of the opening 202 of the cover 20 at the extreme position, ensuring that the cover 19 maintains smooth and unhindered movement throughout the entire flipping stroke, including at the maximum opening angle. This not only improves the user experience but also avoids wear or damage to the mechanism caused by interference. Combining the above technical solutions, regardless of whether the cover 19 flips forward or backward, it is always provided with smooth damping by the flipping adjustment module on one side. The damping gear 203 provides damping force during opening and closing, and the protection of the cover 20 ensures that the entire damping mechanism maintains high reliability and long service life even in harsh environments, thus providing users with a safer, smoother, and more durable bi-directional flipping cover experience.

[0075] like Figure 2As shown in Figures 4 and 5, U-shaped connecting seats 191 are provided on both sides of the lower end face of the cover plate 19; the second end of the connecting rod 204 is hinged to the end of the U-shaped connecting seat 191; when the cover plate 19 does not rotate relative to the connecting rod 204, the main body of the connecting rod 204 is embedded in the U-shaped groove of the U-shaped connecting seat 191. Specifically, U-shaped connecting seats 191 are provided on both sides of the lower end face of the cover plate 19. The U-shaped connecting seat 191 is a structural component with a U-shaped cross-section, whose main function is to provide a stable mounting base for the hinge of the connecting rod 204 and to provide an embedding space for the main body of the connecting rod 204. The U-shaped connecting seat 191 can be integrally formed with the cover plate 19, for example, through injection molding or compression molding processes, thereby ensuring the integrity and strength of the connection. In addition, the U-shaped connecting seat 191 can also be an independent component, which is firmly fixed to both sides of the lower end face of the cover plate 19 by means of screws, rivets, welding or bonding. This method is beneficial for modular production and subsequent maintenance.

[0076] The second end of the connecting rod 204 is hinged to the end of the U-shaped connecting seat 191. A hinge is a connection method that allows two components to rotate relative to each other around a common axis, ensuring that the connecting rod 204 can rotate flexibly during the flipping of the cover plate 19, while maintaining the reliability of the connection to achieve a bidirectional flipping function. The second end of the connecting rod 204 may have holes aligned with corresponding holes on the end of the U-shaped connecting seat 191. A pin or bolt is used to pass through these holes for connection, and it can be fixed using snap rings, nuts, or riveting to prevent detachment. Alternatively, the second end of the connecting rod 204 can be designed as a ball head or ball socket structure, cooperating with the corresponding ball socket or ball head structure on the end of the U-shaped connecting seat 191 to form a ball hinge connection. This connection method, in addition to rotational freedom, may also provide a certain degree of swing freedom to accommodate more complex motion trajectories.

[0077] When the cover plate 19 does not rotate relative to the connecting rod 204, the main body of the connecting rod 204 is embedded in the U-shaped groove of the U-shaped connecting seat 191. "Embedding" refers to one component being accommodated or wrapped by the specific structure of another component, thereby restricting its movement or providing support. The U-shaped groove is a recess inside the U-shaped connecting seat 191. The size and shape of the U-shaped groove of the U-shaped connecting seat 191 are closely matched with the outer shape of the main body of the connecting rod 204. When the cover plate 19 is in a stable state of being fully open or closed, the main body of the connecting rod 204 can be tightly wrapped by the U-shaped groove, eliminating gaps. In addition, the inner wall of the U-shaped groove can also be provided with an elastic pad or a limiting structure. When the main body of the connecting rod 204 is embedded therein, the elastic pad can provide a certain preload, further eliminating gaps and absorbing vibrations, while the limiting structure can prevent the connecting rod 204 from shaking unnecessarily in the non-rotating state.

[0078] Through the above technical solution, this application optimizes the connection structure between the cover plate 19 and the connecting rod 204, effectively solving the problem of unstable connection. Specifically, U-shaped connecting seats 191 are provided on both sides of the lower end face of the cover plate 19, providing a stable installation foundation for the connecting rod 204 and avoiding overall shaking caused by weak connection points. The second end of the connecting rod 204 is hinged to the end of the U-shaped connecting seat 191, ensuring that the hinge point can rotate flexibly to adapt to bidirectional movement during the flipping process of the cover plate 19, while maintaining the reliability of the connection. More importantly, when the cover plate 19 does not rotate relative to the connecting rod 204, the main body of the connecting rod 204 is embedded in the U-shaped groove of the U-shaped connecting seat 191. Utilizing the wrapping characteristics of the U-shaped groove, the gap at the connection point is eliminated, and the mechanical locking effect is enhanced, thereby preventing the cover plate 19 from loosening or making abnormal noises in a static state. This design significantly improves the stability and quietness of the cover 19 operation, allowing users to experience a smooth and reliable operation when opening, closing, or leaving the cover 19 stationary, thereby enhancing the overall quality of the product and user satisfaction.

[0079] like Figure 1-3 As shown, brush assemblies 30 are respectively provided inside the top opening 10 of the main frame 1 at the front and rear edges of the cover plate 19 when it is closed. Specifically, the inside of the top opening 10 of the main frame 1 refers to the inner area of ​​the opening formed by the top edge of the main frame 1. This area provides support and limitation for the cover plate 19 and serves as a reference for installing other components. The front and rear edges of the cover plate 19 when it is closed refer to the areas where its front and rear sides meet or are adjacent to the edge of the top opening 10 when the cover plate 19 is fully closed. These areas are where dust is most likely to enter and where users most frequently come into contact with the cover plate during operation. The brush assembly 30 is a flexible structure made of a flexible material and typically contains multiple fine bristles to fill gaps, provide cushioning, or provide friction. The bristle assembly 30 can be implemented in various ways. For example, it can be a pre-formed strip of bristles that is fixed to the inner wall of the top opening 10 by means of adhesive, snap-fit, or screws. Alternatively, the bristle assembly 30 can be a flexible protrusion structure that is directly injection molded or integrally formed on the corresponding position of the main frame 1, with a texture or branching similar to bristles on its surface. Or, it can be a sealing strip with an elastomer and a bristle-like structure on its surface.

[0080] The bristle assembly 30 provides an operating space for fingers to insert and operate on the cover plate 19. This is achieved by the sufficient flexibility and elasticity of the bristles of the bristle assembly 30. When the user needs to open the cover plate 19, their fingers can easily be inserted into the gap between the cover plate 19 and the main frame 1. The bristles deform, providing a space for the fingers to enter, thus facilitating the user to apply force to open the cover plate 19. This design avoids the need for additional operating grooves, maintaining the flatness and aesthetics of the socket surface. Simultaneously, the bristle assembly 30 also serves a dustproof function. The densely arranged bristles of the bristle assembly 30 form a physical barrier, effectively filling the tiny gap between the cover plate 19 and the edge of the top opening 10. When the cover plate 19 is closed, the bristles are in close contact with the edge of the cover plate 19, forming an effective seal, thereby preventing external dust, debris, and other foreign objects from entering the socket through the gaps, protecting the cleanliness and normal operation of the internal electrical components.

[0081] Through the above technical solution, this application effectively solves the problems of dust prevention and ease of operation when the cover 19 is closed by setting a bristle assembly 30 inside the top opening 10 of the main frame 1 and at the front and rear edges of the cover 19 when it is closed. Specifically, the specific position of the bristle assembly 30 ensures that it is directly located in the core area of ​​the closed area of ​​the cover 19, making it easy to cover critical gaps. Its flexible structure utilizes the elasticity and compressibility of the bristles, allowing users to easily insert their fingers and apply force to open the cover 19 without the need for additional operating grooves, solving the problem of insufficient operating space and greatly improving the convenience of user operation. At the same time, the dense arrangement of the bristles forms an effective physical barrier, which can effectively prevent external dust from seeping into the socket from the edges, keeping the inside clean, thereby extending the service life of the socket and reducing maintenance needs. Overall, this solution improves the user experience while also enhancing the protective performance and reliability of the device.

[0082] The following example will provide a more detailed explanation of the above technical solution:

[0083] In a modern conference room, a recessed power outlet needs to be installed in the center of a large conference table so that conference participants can conveniently use power or data interfaces from either side of the table. Traditional single-direction flip-out outlets cannot meet the needs of users on both sides operating simultaneously, while some existing two-way flip-out outlets have problems such as abrupt and rapid opening and closing of the cover, noise generation, and even the risk of pinching fingers, or overly complex structures and high costs.

[0084] To address these issues, this technical solution provides an embedded socket with a bi-directional flip-up cover. The main frame 1 of the socket is precisely fitted into a pre-drilled hole in the conference table. The top of the main frame 1 has a top frame 102 with a top opening 10. A cover 19 is installed within this top opening 10, which can be flipped open bi-directionally, forward and backward. The core of this socket lies in its unique flip-up adjustment module. A flip-up adjustment module is located on both the left and right sides inside the top opening 10. These two flip-up adjustment modules have identical structures, but their mounting orientation on the main frame 1 is opposite in the front-back direction. This ingenious installation method is key to achieving bi-directional damping.

[0085] Taking one of the tilting adjustment modules as an example, it includes a damper mounted on the main frame 1. Specifically, the damper is a damping gear 203 filled with damping fluid, which ensures smooth damping force during the opening and closing of the cover plate 19. The module also includes a transmission component connecting the damping gear 203 and the cover plate 19. Specifically, the transmission component is a connecting rod 204. The first end of the connecting rod 204 is provided with an arc-shaped toothed plate 221, which meshes with the damping gear 203. The second end of the connecting rod 204 is movably hinged to the cover plate 19. U-shaped connecting seats 191 are provided on both sides of the lower end face of the cover plate 19, and the second end of the connecting rod 204 is hinged to the end of the U-shaped connecting seat 191. When the cover plate 19 does not rotate relative to the connecting rod 204, the main body of the connecting rod 204 is embedded in the U-shaped groove of the U-shaped connecting seat 191, forming a tight connection.

[0086] To protect the damping gear 203 and ensure its stable operation, a cover 20 is also included, which is fixed to the side wall of the top opening 10. The damping gear 203 is housed inside the cover 20. The upper end of the cover 20 has an opening 202 and a hinge seat 201 located next to the opening 202. The first end of the connecting rod 204 is rotatably connected to the hinge seat 201. The arc-shaped toothed plate 221 passes through the opening 202 and meshes with the damping gear 203. When the cover 19 is opened to its maximum angle, a section of the arc-shaped toothed plate 221 will rotate out of the opening 202 with the connecting rod 204 to accommodate the flipping stroke of the cover 19.

[0087] Now, let's explain in detail how it works:

[0088] When a user needs to open cover 19 from the front of the conference table, they flip cover 19 forward. At this time, the connecting rod 204 of the flip adjustment module on the left side of cover 19 rotates with cover 19, and its arc-shaped toothed plate 221 continuously engages with the damping gear 203 on that side, thereby driving the damping gear 203 to provide damping force. This allows cover 19 to open smoothly and slowly, avoiding the impact and noise caused by rapid flipping. At the same time, the connecting rod 204 of the flip adjustment module on the right side of cover 19 will rotate relative to cover 19, that is, the arc-shaped toothed plate 221 of the connecting rod 204 will disengage from its corresponding damping gear 203 or will not generate effective drive, so the damping gear 203 on that side will not provide damping force.

[0089] Conversely, when the user needs to open the cover 19 from behind the conference table, they flip the cover 19 backward. At this time, the drive and relative rotation relationship of the two flip adjustment modules will be reversed. The connecting rod 204 of the rear flip adjustment module, which originally rotated relative to the cover 19, will now rotate with the cover 19 and drive its damping gear 203 to provide damping force. The connecting rod 204 of the front flip adjustment module will rotate relative to the cover 19 and will not provide damping.

[0090] Through this ingenious configuration, regardless of whether the cover 19 flips forward or backward, the flipping damping is always provided by the flipping adjustment module on one side. This design avoids the complexity of two-way hinges or pivot mechanisms in existing technologies and also solves the problems of insufficient or uneven damping. Compared with the simple free-flipping cover in existing technologies, the cover 19 in this solution operates smoothly and in a controlled manner when opening and closing, significantly improving the user experience, reducing impact noise, and effectively avoiding the risk of pinching fingers.

[0091] Furthermore, to further enhance the user experience and dustproof effect, brush components 30 are respectively provided inside the top opening 10 of the main frame 1 at the front and rear edges when the cover plate 19 is closed. These brush components 30 not only provide users with operating space to insert their fingers to operate the cover plate 19, but also effectively prevent dust and keep the inside of the socket clean.

[0092] This technical solution achieves a stable and controlled damping effect for the cover plate 19 during bidirectional flipping by using two simple, oppositely oriented flipping adjustment modules. This effectively solves many problems existing in the current bidirectional flipping cover plate, while also taking into account production cost and ease of assembly.

[0093] like Figure 6-13As shown, this embodiment also includes a base bracket 2 for fixing the socket body 9. The base bracket 2 is detachably connected to the main frame 1. The core of this solution is that the base bracket 2 is detachably connected to the main frame 1, and can adjust the installation height of the socket body 9 by changing the installation orientation or sliding and positioning it longitudinally along the main frame, or a combination thereof, thereby changing the depth of the socket cavity to accommodate plugs of different sizes. The base bracket 2 is constructed as a 'U' or 'V' shaped bracket and has two basic states: forward installation and reverse installation. Forward installation means that the base bracket 2 is connected to the main frame 1 with its opening facing upward; reverse installation means that the base bracket 2 is connected to the main frame 1 with its opening facing downward. By switching between these two installation states, a large adjustment of the installation height of the socket body 9 can be achieved.

[0094] exist Figure 1 In several other embodiments shown in 6-9, the main frame 1 includes side supports 101 disposed on opposite sides, and a top frame 102 connecting the side supports 101 on both sides; the main frame 1 is used to be fitted into the table hole of the tabletop. In this embodiment, the top frame 102 has a top opening 10 directly above the base support 2, and a cover plate 19 is rotatably disposed in the top opening 10. The cover plate 19 can adopt any flip-up structure, thereby realizing adjustment between the closed and open states.

[0095] In the specific design, the main frame 1 can be fixed to the table hole by clamping, with attachments... Figure 2 and 7 In the main frame 1, a positioning rack 11 is provided on the support leg, and a clamping component 12 is provided on the positioning rack 11. After the clamping component 12 moves longitudinally into place on the positioning rack 11, it can be tightened based on the screw in the clamping component 12 to cooperate with the retaining ring on the upper edge of the main frame 1 to clamp the upper and lower sides of the table hole and achieve a fixed connection.

[0096] In this embodiment, the base bracket 2 is installed relative to the main frame 1 in at least the following ways:

[0097] The first installation method is as follows: Figure 6 and 7 As shown: The base bracket 2 is installed in the front at the lower end of the main frame 1. The "U"-shaped opening or V-shaped opening of the base bracket 2 faces upward and can slide and be positioned longitudinally along the main frame 1.

[0098] In the first installation method, the base bracket 2 is installed at the lower end of the main frame 1 and can slide and be positioned longitudinally along the base bracket 2, thereby adjusting the distance between the socket body 9 on the base bracket 2 and the top opening 10 of the main frame 1. The technical solution of this application achieves adjustment of the distance between the socket body 9 and the top opening 10 of the main frame 1 through the longitudinal sliding and positioning of the base bracket 2. This design allows the depth of the socket cavity to be adjusted as needed, thereby accommodating plugs of different sizes and improving the versatility and ease of use of the socket. Compared with the prior art, the technical solution of this application solves the problem that the fixed cavity depth cannot adapt to different plugs, avoiding inconvenience in plug insertion and power access or the inability to close the cover, demonstrating significant practicality and innovation.

[0099] In the above scheme, the longitudinal sliding and positioning of the base support 2 can be achieved in various ways. For example, the base support 2 can be designed with a slide rail structure, which engages with a groove on the main frame 1, allowing the base support 2 to slide longitudinally along the groove. Furthermore, positioning holes can be provided on the slide rail, and the base support 2 can be positioned by inserting a positioning pin or tightening a positioning screw. Specifically, the sliding and positioning of the base support 2 can also be achieved through a gear and rack mechanism, with a rack on the base support 2 and a gear on the main frame 1. Rotating the gear drives the rack to move, thereby achieving the sliding and positioning of the base support 2. As a preferred embodiment, the sliding and positioning of the base support 2 can also be achieved through a hydraulic or pneumatic drive device, precisely adjusting the position of the base support 2 by controlling the input and output of hydraulic or pneumatic pressure.

[0100] In a specific implementation, at least two opposite side walls or four corners of the main frame 1 are provided with downwardly extending legs 13, i.e., legs 13 extend downwardly from both sides of the two side supports 101. The base support 2 is longitudinally movably mounted on the legs 13 and can be positioned. The legs 13 can be constructed in various ways, for example, made of metal or plastic materials, and fixed to the main frame 1 by welding, bolting, or snap-fitting. The shape of the legs 13 can be straight, L-shaped, or other suitable shapes to ensure that the base support 2 can slide longitudinally. The longitudinal movement of the base support 2 can be achieved by structures such as slide rails, grooves, or rollers, while the positioning function can be achieved by locking mechanisms, snap-fitting, or magnetic devices. In the above scheme, the base support 2 is longitudinally movably mounted on the legs 13, allowing the base support 2 to slide longitudinally along the legs 13 and be fixed in the desired position by the positioning function. This design allows the socket body 9 on the base bracket 2 to be adjusted relative to the top opening 10 of the main frame 1, thereby accommodating power plugs of different sizes and solving the problem that the depth of the fixed box cavity cannot accommodate different plugs. Compared with the prior art, this application achieves flexible adjustment of the socket body 9 through the cooperation of the support leg 13 and the base bracket 2, improving the applicability and ease of use of the recessed socket.

[0101] In combination Figure 10-12 In the specific embodiment shown, each leg 13 of the main frame 1 is equipped with a longitudinally arranged adjusting rack 14. The base support 2 is provided with positioning teeth 21 and a control component for driving the positioning teeth 21 forward and backward. When the base support 2 slides on the leg 13, the positioning teeth 21 move relative to the adjusting rack 14 and engage with it based on the control of the control component. The adjusting rack 14 is a toothed structure longitudinally arranged on the leg 13, used to provide precise guidance and positioning reference. The positioning teeth 21 are toothed structures arranged on the base support 2, capable of engaging with the adjusting rack 14, thereby achieving precise positioning of the base support 2 during sliding. The control component includes a drive mechanism and a reset mechanism. The drive mechanism drives the positioning teeth 21 forward and backward, and the reset mechanism resets the positioning teeth 21 when they disengage from the adjusting rack 14. Specifically, when the base bracket 2 slides on the support leg 13, the positioning tooth 21 is driven to move forward and backward by the control component, causing the positioning tooth 21 to engage or disengage with the adjusting rack 14, thereby achieving precise positioning and fixation of the base bracket 2. Thus, the base bracket 2 can achieve precise positioning and fixation during sliding, solving the technical problem of the base bracket 2 being unable to achieve precise positioning and fixation during sliding. Compared with the prior art, this application achieves precise positioning and fixation of the base bracket 2 during sliding through the mutual cooperation of the adjusting rack 14, the positioning tooth 21, and the control component, improving the practicality and reliability of the embedded socket.

[0102] exist Figure 11-13 In the specific embodiment shown, the base support 2 is constructed as an upward-opening "U" or "V" shaped support. The input end of the control component protrudes from the bottom or side of the base support 2, and the positioning teeth 21 are arranged on the top of the "U" or "V" shaped base support 2. The top of the "U" or "V" shaped base support 2 is longitudinally slidably mounted on the support leg 13. Pressing the input end of the control component controls the forward and backward movement of the positioning teeth 21. Specifically, the input end of the control component can be designed as a button or lever, protruding from the bottom or side of the base support 2 for easy user operation. The positioning teeth 21 can be designed as serrated or rack-shaped, arranged on the top of the "U" or "V" shaped base support, so that when the base support 2 slides longitudinally, the positioning teeth 21 can effectively engage with the adjusting rack 14 to achieve precise positioning. The design of the input end of the control component and the position of the positioning teeth 21 allows the positioning teeth 21 to be directly driven forward and backward when the control component is pressed, simplifying the operation steps and improving the convenience of operation. This design not only optimizes the structure of the base bracket 2, but also improves its stability and reliability during use.

[0103] like Figure 11 and 12As shown, the control assembly includes a control button 22 embedded in the base bracket 2, an elastic component for resetting the control button 22, and a drive rod 23 connected to the control button 22. The control button 22 protrudes from the bottom surface of the base bracket 2, and the drive rod 23 is located within the side wall of the base bracket 2. The lower end of the drive rod 23 slides in a wedge-shaped inclined surface with the side of the control button 22, and a positioning tooth 21 is provided on the upper end of the drive rod 23. Specifically, the control button 22 can be designed as a button or a toggle, and its protruding part facilitates user pressing or toggling. The elastic component can be a spring or an elastic sheet to ensure that the control button 22 can automatically reset after operation. The lower end of the drive rod 23 slides in a wedge-shaped inclined surface with the side of the control button 22, a design that allows the drive rod 23 to accurately respond to the operation of the control button 22. The positioning tooth 21 can be designed as a sawtooth or a rack to engage or disengage with the adjusting rack 14. In a preferred embodiment, the upper end of the drive rod 23 can be provided with multiple positioning teeth 21 to increase the accuracy and stability of positioning. Thus, this technical solution achieves precise control of the positioning teeth 21 through the cooperation of the control button 22, the elastic component, and the drive rod 23. The control button 22 is embedded in the base bracket 2 for easy user operation and to reduce external interference. The elastic component ensures that the control button 22 automatically resets after operation, improving ease of use and reliability. The drive rod 23 and the control button 22 slide together via a wedge-shaped inclined surface. This design allows the drive rod 23 to accurately respond to the operation of the control button 22, thereby achieving precise control of the positioning teeth 21. The positioning teeth 21 are located at the upper end of the drive rod 23. Through the movement of the drive rod 23, the positioning teeth 21 can engage or disengage with the adjusting rack 14, realizing the positioning and adjustment of the base bracket 2. In actual use, the control button 22 moves longitudinally under external pressure or after the external force is removed, and slides against the wedge-shaped inclined surface at the lower end of the drive rod 23 through its side, thereby driving the drive rod 23 and its positioning teeth 21 to move laterally forward and backward. Compared with the prior art, this technical solution has the advantages of simple operation, accurate positioning, and high reliability.

[0104] In addition to the installation methods described above, this solution also provides a second installation method, such as... Figure 8As shown: The base bracket 2 is installed in reverse at the lower end of the main frame 1, with the "U"-shaped or V-shaped opening of the base bracket 2 facing downwards. At this time, with the "U"-shaped or V-shaped opening of the base bracket 2 facing downwards, the socket body 9 is fixed to the top or side surface of the base bracket 2. Specifically, the "U"-shaped structure design of the base bracket 2 allows it to be installed upside down on the support leg 13, with the "U"-shaped or V-shaped opening facing downwards. This design allows the socket body 9 to be securely fixed to the top surface of the base bracket 2. Compared with the prior art, this application significantly improves the installation height of the socket body 9 by installing the "U"-shaped base bracket 2 upside down, which is suitable for situations where the socket cavity depth requirement is shallow and exceeds the sliding adjustment range. This design not only improves the installation stability of the socket body 9 but also simplifies the installation and adjustment process, possessing high practicality and innovation.

[0105] In addition to the installation methods mentioned above, this solution also provides a third installation method, such as... Figure 9-11 The main frame 1 has longitudinally provided grooves 15 on the legs 13 extending downwards from at least the rear side wall or the two rear corners, and the base support 2 has sliding columns 25. The sliding columns 25 of the base support 2 can slide into or out of the grooves 15 on the legs 13 and can slide longitudinally along the grooves 15. Specifically, the grooves 15 can be designed as straight lines or curves to adapt to different sliding requirements. The sliding columns 25 can be cylindrical, square, or other geometric shapes to ensure the accuracy and stability of the fit with the grooves 15. The depth and width of the grooves 15 can be precisely designed according to the dimensions of the sliding columns 25 to prevent jamming or loosening during sliding. In addition, the materials of the grooves 15 and the sliding columns 25 can be selected as wear-resistant and corrosion-resistant metals or plastics to extend their service life. Thus, this technical solution realizes the longitudinal sliding adjustment of the base support 2 on the legs 13 of the main frame 1 through the cooperation of the grooves 15 and the sliding columns 25. This design makes the sliding of the base support 2 more stable and precise, and facilitates user adjustment according to actual needs. Compared with existing technologies, this solution not only solves the technical problem of sliding adjustment between the base bracket 2 and the main frame 1 in the embedded socket, but also improves the flexibility of adjustment and the convenience of operation.

[0106] In the specific design, the slide groove 15 on the support leg 13 includes a longitudinally arranged main slide 151 and an inlet channel 152 communicating with the bottom of the main slide 151. A suspension groove 153 is constructed directly below the main slide 151, and the inlet channel 152 avoids the suspension groove 153. The sliding column 25 of the base bracket 2 can be engaged in the suspension groove 153. When the front end of the base bracket 2 disengages from the front support leg 13, the base bracket 2 rotates around the sliding column 25 as its axis, leaving a bottom power outlet between the front end of the base bracket 2 and the main frame 1. The main slide 151 is a longitudinally arranged channel, allowing the sliding column 25 of the base bracket 2 to slide longitudinally within it. The inlet channel 152 communicates with the bottom of the main slide 151 and is used to guide the sliding column 25 into the suspension groove 153. The suspension groove 153 is located directly below the main slide rail 151. The design of the guide channel 152 avoids the suspension groove 153, ensuring that the sliding post 25 can smoothly engage with the suspension groove 153. After the sliding post 25 of the base bracket 2 engages with the suspension groove 153, the front end of the base bracket 2 disengages from the front support leg 13, and the base bracket 2 flips around the sliding post 25 as its axis, thereby forming a bottom power outlet between the front end of the base bracket 2 and the main frame 1. Specifically, the sliding post 25 can enter the suspension groove 153 through the guide channel 152 and be fixed within the suspension groove 153, ensuring the stability of the base bracket 2 during the flipping process. As a preferred embodiment, the guide channel 152 can be designed as an inclined channel so that the sliding post 25 can more easily enter the suspension groove 153. In addition, the depth and shape of the suspension groove 153 can be optimized according to the size of the sliding post 25 to ensure that the sliding post 25 can be firmly engaged within it. Therefore, the technical solution of this application, by setting a main slide rail 151, an inlet channel 152, and a suspension groove 153 on the support leg 13, allows the sliding column 25 of the base bracket 2 to slide longitudinally within the main slide rail 151 and enter the suspension groove 153 through the inlet channel 152. When the front end of the base bracket 2 disengages from the front support leg 13, the base bracket 2 rotates around the sliding column 25 as its axis, thereby forming a bottom power outlet between the front end of the base bracket 2 and the main frame 1. This design allows the embedded socket to draw power not only from the top opening 10 but also from below the desktop through the bottom power outlet, meeting the needs of different users. Compared with the prior art, the technical solution of this application, through a simple structural design, achieves diversified power draw methods and improves the practicality and flexibility of the embedded socket.

[0107] In addition, such as Figure 11-13As shown, the base support 2 includes a base body 26 and adjustable frames 27 detachably fixed to both sides of the base body 26. The control components and positioning teeth 21 are both located within the adjustable frames 27. The base body 26 is longitudinally movable on the support legs 13 based on the adjustable frames 27 on both sides and can be positioned. Specifically, the detachable connection between the base body 26 and the adjustable frames 27 can be achieved through bolts, clips, or other mechanical connections, facilitating maintenance and replacement. Therefore, this technical solution simplifies the structure of the base support 2 and improves the convenience and stability of adjustment by integrating the control components and positioning teeth 21 within the adjustable frames 27. The detachable connection between the base body 26 and the adjustable frames 27 not only facilitates maintenance and replacement but also allows for the replacement of different styles of base bodies 26 as needed, further enhancing the practicality and reliability of the product. Furthermore, the above solution states that the control button 22 is located on the adjustable frames 27, and it actually protrudes from the bottom surface of the adjustable frames 27 of the base support 2. Compared with existing technologies, this solution solves the technical problems of complex structure and inconvenient adjustment of the base support 2 during longitudinal movement and positioning, and has significant technical advantages.

[0108] In the specific design, the base body 26 is constructed in a U-shape or V-shape with the opening facing upwards. For example... Figure 6 and 7 As shown in Figures 11 and 12, a strip-shaped hole 261 is provided on the side wall and / or bottom surface of the base body 26, and the bottom of the socket body 9 is fixedly connected to the strip-shaped hole 261 on the side wall or bottom surface of the base body 26. In this design, the design of the strip-shaped hole 261 allows the bottom of the socket body 9 to be connected to the base body 26 by bolts or other fasteners, thereby achieving a stable fixation. The length and width of the strip-shaped hole 261 can be adjusted according to the size of the socket body 9 to accommodate different models of socket bodies 9. Figure 13In another embodiment shown, a mounting opening 262 is provided on the side wall and / or bottom surface of the base body 26. The socket body 9 is embedded in the mounting opening 262, with the edge of the socket body 9 engaging with the edge of the mounting opening 262. The rear end of the socket body 9 passes through the mounting opening 262 and is located on the outside of the base body 26. In this embodiment, the design of the mounting opening 262 allows the socket body 9 to be embedded in the base body 26, and the edge of the socket body 9 engages with the edge of the mounting opening 262, ensuring that the socket body 9 will not loosen after installation. The rear end of the socket body 9 passes through the mounting opening 262 and is located on the outside of the base body 26, facilitating the disassembly and replacement of the socket body 9. Thus, the technical solution of this application solves the problem of fixing and installing the socket body 9 and the base body 26 in an embedded socket through the design of the "U" or "V" shaped structure, the strip hole 261, and the mounting opening 262 of the base body 26. This solution can adapt to socket bodies 9 of different sizes and models, and ensures their stability and detachability. Compared with the prior art, the technical solution of this application has greater flexibility and adaptability, can meet a variety of usage needs, and simplifies the installation and disassembly process, thus improving ease of use.

[0109] To meet users' power consumption habits or adapt to their usage environment, the above-mentioned recessed sockets offer the following four installation methods:

[0110] Installation method one, such as Figure 6 and 7 The base body 26 is mounted on the support leg 13 of the main frame 1. In this configuration, the "U" or "V" shaped opening of the base body 26 faces upward, and its height can be adjusted based on the adjusting rack 14 to meet different socket cavity depth requirements.

[0111] Installation method two, such as Figure 8 When the required socket cavity depth is shallow and exceeds the sliding adjustment range of installation method one, the "U"-shaped structure design of the base bracket 2 allows it to be installed upside down on the support leg 13 with the "U"-shaped opening facing downwards. This design enables the socket body 9 to be securely fixed to the top surface of the base bracket 2. Compared with the prior art, this application significantly improves the installation height of the socket body 9 by installing the "U"-shaped base bracket 2 upside down.

[0112] Installation method three, such as Figure 9 When you want to use it as an under-table socket, the sliding post 25 of the base bracket 2 enters the hanging groove 153, so that the front end of the base bracket 2 is separated from the front support leg 13. The base bracket 2 rotates around the sliding post 25 as the axis, thereby forming a bottom power outlet between the front end of the base bracket 2 and the main frame 1.
