[0002] In traditional electrical box designs, the support structure is mostly horizontally arranged, such as the common sliding window or flip-up support structure. While this type of structure has good stability, it is difficult to meet the requirements for the opening angle and direction of the door, as well as the utilization of internal space, in some space-constrained applications. In addition, existing support structures occupy a large amount of space in the height direction, making it difficult to adapt to the modern trend of miniaturization and thinning of electrical boxes. Utility Model Content

[0003] The main purpose of this utility model is to propose an electrical box support structure, which aims to improve applicability and suitability for use in confined spaces.

[0004] To achieve the above objectives, this utility model proposes an electrical box support structure, comprising: Frame assembly for mounting on a mounting surface where an electrical box is located; The cover is movably connected to the frame assembly; A linkage component, one end of which is connected to the frame component and the other end of which is connected to the cover, is capable of driving the cover to move laterally away from or cover the frame component, thereby moving the cover away from or covering the electrical box; and The cover has a first position and a second position. In the first position, the cover is stacked on the frame assembly. In the second position, the cover is parallel to and offset from the mounting surface of the frame assembly.

[0005] In one embodiment, the frame component includes a first frame, a second frame, a third frame, and a fourth frame that are interconnected. The first frame and the third frame extend along a first direction, and the second frame and the fourth frame extend along a second direction. The first direction and the second direction intersect each other. The linkage component includes a first link, a second link, and a third link. One end of the first link is movably connected to the first frame, and the other end of the first link is movably connected to the cover. One end of the second link is movably connected to the third frame, and the other end of the second link is movably connected to the cover. The third link is movably connected to the second frame and the third link is movably connected to the cover. The first link, the second link, and the third link drive the cover to move away from or cover the frame assembly along the lateral direction.

[0006] In one embodiment, the first link, the second link, the third link, and the cover are configured to form a parallelogram structure.

[0007] In one embodiment, the third link includes a first connecting portion, a second connecting portion, and a third connecting portion. The first connecting portion extends along the second direction and is disposed on the second frame. One end of the second connecting portion and the third connecting portion is disposed opposite to the first connecting portion. The other end of the second connecting portion and the third connecting portion is movably connected to the cover.

[0008] In one embodiment, the second connecting portion, the third connecting portion, the first connecting rod, and the second connecting rod are of equal length.

[0009] In one embodiment, the electrical box support structure further includes a hinge assembly, wherein the first connecting rod and the first frame are hingedly connected by the hinge assembly, the second connecting rod and the third frame are hingedly connected by the hinge assembly, the first connecting part and the second frame are hingedly connected by the hinge assembly, the second connecting part and the cover are hingedly connected by the hinge assembly, and the third connecting part and the cover are hingedly connected by the hinge assembly.

[0010] In one embodiment, the hinge assembly is configured as a hinge structure.

[0011] In one embodiment, the electrical box support structure further includes a magnetic attraction component, in which the frame assembly and the cover are attracted together by the magnetic attraction component when in the first position.

[0012] In one embodiment, the cover includes a first support body, a second support body, a third support body, and a fourth support body connected in sequence; The magnetic suction assembly includes a first magnetic suction element, a second magnetic suction element, a third magnetic suction element, and a fourth magnetic suction element. The first magnetic suction element is located at the connection between the first support body and the second support body. The second magnetic suction element is located at the connection between the second support body and the third support body. The third magnetic suction element is located at the connection between the third support body and the fourth support body. The fourth magnetic suction element is located at the connection between the fourth support body and the first support body.

[0013] In one embodiment, the electrical box support structure further includes a gasket located between the magnetic assembly and the cover.

[0014] This utility model presents an electrical box support structure. Its core feature lies in the use of a linkage component to drive the cover to slide and switch between two specific positions, achieving efficient protection and convenient operation of the electrical box. The frame assembly is fixedly installed on a wall, cabinet, or other mounting surface to support and position the entire structure. The cover is movably connected to the frame assembly to cover or open the electrical box. One end of the linkage component is connected to the frame assembly, and the other end is connected to the cover, enabling the cover to move laterally (parallel to the mounting surface but laterally), moving it from a first position covering the electrical box to a second position further away from the box for easier operation. In the first position, the cover overlaps the frame assembly, completely covering the front of the electrical box, providing dustproof, waterproof, and protective functions. In the second position, the cover remains parallel to the mounting surface and is offset from the frame assembly, not obstructing the operating area of ​​the electrical box, facilitating maintenance or wiring. Compared to traditional electrical box structures that use a hinged flip-open mechanism, which often results in the cover not fully fitting against the wall, leading to noticeable gaps after hanging artwork, protrusions from the wall, and negatively impacting the decorative effect, this invention eliminates exposed hinges or pivots. It adopts a lateral sliding opening method, significantly improving overall concealment and aesthetics. Through a sliding structure without exposed rotating parts, the cover is flush with the wall when closed, greatly reducing visual obtrusion and perfectly meeting the needs of concealed indoor installation. It is particularly suitable for embedded electrical boxes in residential and commercial spaces where decorative appeal is paramount. Attached Figure Description

[0022] This utility model proposes an electrical box support structure.

[0023] Reference Figures 1 to 5In this embodiment of the utility model, an electrical box support structure includes: Frame assembly 10, for mounting on a mounting surface where an electrical box is located; The cover 20 is movably connected to the frame assembly 10; A linkage component 30, one end of which is connected to the frame assembly 10 and the other end of which is connected to the cover 20, is capable of driving the cover 20 to move laterally away from or cover the frame assembly 10, so that the cover 20 moves away from or covers the electrical box; and The cover 20 has a first position and a second position. In the first position, the cover 20 is stacked on the frame assembly 10. In the second position, the cover 20 is parallel to and offset from the mounting surface of the frame assembly 10.

[0024] This utility model discloses an electrical box support structure including a frame assembly 10. The frame assembly 10 is installed on a mounting surface where the electrical box is located. The mounting surface can be, but is not limited to, a wall or cabinet. The frame assembly 10 provides support and positioning. A cover 20 is movably connected to the frame assembly 10 and can be in two key positions. In the first position, the cover 20 is stacked on top of the frame assembly 10, covering the electrical box. In the second position, the plane of the cover 20 is parallel to but offset from the plane of the frame assembly 10, exposing the electrical box. A linkage assembly 30 connects the mechanical transmission components between the frame assembly 10 and the cover 20, driving the cover 20 to move laterally, switching between the first and second positions. When open, the cover 20 does not occupy the front space but is offset, making it suitable for use in confined spaces. Simultaneously, the cover does not obstruct the front of the electrical box, facilitating maintenance. When closed, the cover 20 is stacked on top of the frame assembly 10, providing protection and ensuring the overall structural stability and sealing. It can be used in various electrical box scenarios such as distribution boxes and control boxes, facilitating maintenance and protecting internal components. It is understood that the lateral direction refers to the direction consistent with the opening and closing direction of the cover 20 relative to the frame assembly 10, a horizontal direction parallel to the mounting surface of the frame assembly 10 and perpendicular to the closing direction of the cover 20. The cover does not flip back and forth or flip up and down. Through this lateral movement, the cover 20 can switch from the first position to the second position without flipping or lifting, thereby avoiding occupying extra space, improving operational convenience and structural stability, and enabling the cover 20 to complete the opening and closing operation of the electrical box without changing the vertical spatial layout. Furthermore, when the user needs to open the electrical box, the linkage component 30 drives the cover 20 to move along this lateral direction, so that it is offset from the frame assembly 10 and does not obstruct the electrical box; when closing the electrical box, the linkage component 30 drives the cover 20 to move in the opposite direction, so that it is stacked on top of the frame assembly 10 again to achieve sealing and protection. The design of this structure aims to create an electrical box protective device that is easy to open and close, flexible in operation, and has good sealing performance. The cover 20 opens by lateral movement (rather than flipping), which is a significant improvement over traditional electrical box structures that use a hinge to flip open. Traditional hinge structures often result in the cover not fully fitting against the wall, leading to noticeable gaps after hanging pictures, protrusions from the wall, and negatively impacting the decorative effect. This invention eliminates exposed hinges or hinges, adopting a lateral sliding opening method, significantly improving overall concealment and aesthetics. The sliding structure without exposed rotating parts ensures the cover is flush with the wall when closed, greatly reducing visual obtrusion and perfectly meeting the needs of concealed indoor installation. It is particularly suitable for embedded electrical boxes in residential and commercial spaces where decorative aesthetics are paramount. The linkage component 30 enables automatic or manual lateral movement of the cover 20, allowing the electrical box to be opened without complete disassembly, facilitating maintenance. When switching between the two positions, the cover 20 remains parallel to the mounting surface, avoiding stress concentration or deformation risks caused by tilting.

[0025] Reference Figures 1 to 5 In this embodiment of the present invention, the frame component 10 includes a first frame 11, a second frame 12, a third frame 13 and a fourth frame 14 that are connected to each other. The first frame 11 and the third frame 13 extend along a first direction, and the second frame 12 and the fourth frame 14 extend along a second direction. The first direction and the second direction intersect each other. The linkage component 30 includes a first link 31, a second link 32, and a third link 33. One end of the first link 31 is movably connected to the first frame 11, and the other end of the first link 31 is movably connected to the cover 20. One end of the second link 32 is movably connected to the third frame 13, and the other end of the second link 32 is movably connected to the cover 20. The third link 33 is movably connected to the second frame 12 and the cover 20. The first link 31, the second link 32 and the third link 33 drive the cover 20 to move away from or cover the frame assembly 10 in the lateral direction.

[0026] The frame assembly 10 forms the foundation of the entire bracket, used to fix the electrical box and provide support. The frame assembly 10 includes four interconnected frames: the first frame 11 and the third frame 13 extend along a first direction, and the second frame 12 and the fourth frame 14 extend along a second direction. These two directions intersect (can be perpendicular), thus forming an approximately rectangular or square mounting area. This four-sided frame structure provides good structural stability and installation adaptability, suitable for the installation needs of electrical boxes of different sizes. It can be understood that when the electrical box is mounted on a vertical wall, the first direction can be understood as the horizontal direction, i.e., the left-right direction. The second direction can be understood as the vertical direction, i.e., the up-down direction, which is one of the most common application scenarios. In some special cases, such as when the electrical box is designed with a longitudinal layout or when the influence of gravity needs to be specially considered, the first direction can also be set as the vertical direction, i.e., the up-down direction. This means that the first frame 11 and the third frame 13 will extend along the up-down direction, while the second frame 12 and the fourth frame 14 will extend along the left-right direction. The linkage component 30 is the key part for realizing the translation of the cover 20. It includes three links: the first link 31 connects the first frame 11 and the cover 20; the second link 32 connects the third frame 13 and the cover 20; and the third link 33 connects the second frame 12 and the cover 20. These links are all movable, meaning they can rotate or swing freely within a certain range. When the user operates the linkage component (either manually or electrically), these three links work together to move the cover 20 along a set lateral direction. The combined action of multiple links ensures that the cover remains balanced throughout the movement, preventing swaying or tilting. This multi-point linkage design provides better stability and safety for the cover's operation than a single hinge structure. In this embodiment, the electrical box is installed on a vertical wall, so the lateral direction is horizontal, specifically the direction of left-right movement along the mounting surface. The first direction can be considered horizontal, i.e., left-right. The second direction is vertical, i.e., up-down. For example, when a user needs to open the electrical box, the linkage component 30 drives the cover 20 to move in the horizontal direction, so that it is offset from the frame component 10 and does not obstruct the electrical box; when the electrical box is closed, the linkage component 30 drives the cover 20 to move in the opposite direction, so that it is stacked on top of the frame component 10 to achieve sealing protection.

[0027] Reference Figures 1 to 5 In this embodiment of the present invention, the first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the cover 20 are configured to form a parallelogram structure.

[0028] The parallelogram structure design allows the cover 20 to slide out laterally instead of rotating. This saves space in front, making it suitable for confined or densely populated areas, avoiding collision risks, and preventing it from hitting equipment or people when opening. Once fully open, the cover 20 exposes the entire front of the electrical box for easy maintenance. In the parallelogram mechanism, the cover 20 remains parallel to its initial position throughout the entire movement. As the cover slides from the closed to the open state, it remains parallel to the mounting surface (such as a wall), without tilting, shaking, or angle changes, improving the overall structure's sealing, dustproof, and waterproof performance, making it safer and more reliable. Multiple support points distribute the force, reducing the load on a single hinge or guide rail. By adjusting the length of each link or the position of the connection point, the movement path of the cover can be controlled. Compared to a sliding rail guide, the linkage mechanism relies less on metal sliding, reducing the risk of wear. In this embodiment, the thickness of the first link 31 and the second link 32 is preferably 3mm.

[0029] Reference Figures 1 to 5 In this embodiment of the present invention, the third connecting rod 33 includes a first connecting part 331, a second connecting part 332 and a third connecting part 333. The first connecting part 331 extends along the second direction and is disposed on the second frame 12. One end of the second connecting part 332 and the third connecting part 333 is disposed opposite to the first connecting part 331. The other end of the second connecting part 332 and the third connecting part 333 is movably connected to the cover 20.

[0030] The third link 33, as an important component of the linkage assembly 30, is responsible for transmitting torque and moving the cover 20. Adopting a three-part combined structure, the first connecting part 331 serves as the main beam, providing basic support. It is simultaneously connected to the cover 20 through two connecting parts (the second connecting part 332 and the third connecting part 333), forming a dual-support system. This system disperses the force, making the cover 20 more evenly stressed, preventing deflection or instability during sliding, improving the smoothness of operation, and reducing vibration or abnormal noise. In this embodiment, the thickness of the first connecting part 331, the second connecting part 332, and the third connecting part 333 is preferably 2mm.

[0031] Reference Figures 1 to 5 In this embodiment of the present invention, the lengths of the second connecting part 332, the third connecting part 333, the first connecting rod 31, and the second connecting rod 32 are equal.

[0032] The second connecting part 332 and the third connecting part 333 form two support points. The first connecting rod 31 and the second connecting rod 32 are respectively connected to different parts of the frame assembly 10. The four connecting rods are of equal length, forming a parallelogram structure with equal sides. The cover 20 will not tilt or flip when moving and will always remain in a horizontal state. When the four connecting rods are of equal length and the structure is symmetrical, the cover 20 will not shift, jam, or shake, making operation smoother.

[0033] Reference Figures 1 to 5 In this embodiment of the present invention, the electrical box support structure further includes a hinge assembly 40. The first connecting rod 31 and the first frame 11 are hingedly connected through the hinge assembly 40. The second connecting rod 32 and the third frame 13 are hingedly connected through the hinge assembly 40. The first connecting part 331 and the second frame 12 are hingedly connected through the hinge assembly 40. The second connecting part 332 and the cover 20 are hingedly connected through the hinge assembly 40. The third connecting part 333 and the cover 20 are hingedly connected through the hinge assembly 40.

[0034] All hinged connections mentioned in this solution can use the same type of hinge assembly 40. This is to ensure that all connection points have the same kinematic characteristics, avoid frictional differences or inconsistent rotational resistance between different structures, improve the coordination and synchronization of the entire linkage system, and make it easier to control the attitude and trajectory of the cover during the entire sliding process. Each hinge assembly 40 provides these components with a limited degree of rotational freedom, allowing the cover to slide smoothly along a predetermined trajectory.

[0035] Reference Figures 1 to 5 In this embodiment of the present invention, the hinge assembly 40 is configured as a hinge structure.

[0036] Hinges are a mature and widely used type of hinge, characterized by their simple structure and easy installation. For applications like electrical box brackets that require frequent switching, hinges provide sufficient strength and stability. In this embodiment, the total thickness of the hinge structure is controlled to within 1mm to meet the requirements of a lightweight and thin design for the electrical box bracket structure.

[0037] Reference Figures 1 to 5 In this embodiment of the utility model, the electrical box bracket structure further includes a magnetic attraction component 50. In the first position, the frame component 10 and the cover 20 are attracted together by the magnetic attraction component 50.

[0038] The cover 20 does not rely on gravity or mechanical latches to keep it closed, but instead uses magnetic attraction to actively attach it to the frame assembly 10. This improves the stability and sealing of the cover 20 when closed, preventing the cover from being accidentally opened due to vibration, wind or external force.

[0039] Reference Figures 1 to 5 In this embodiment of the present invention, the cover 20 includes a first support body 21, a second support body 22, a third support body 23, and a fourth support body 24 connected in sequence. The magnetic attraction assembly 50 includes a first magnetic attraction member 51, a second magnetic attraction member 52, a third magnetic attraction member 53, and a fourth magnetic attraction member 54. The first magnetic attraction member 51 is located at the connection between the first support body 21 and the second support body 22. The second magnetic attraction member 52 is located at the connection between the second support body 22 and the third support body 23. The third magnetic attraction member 53 is located at the connection between the third support body 23 and the fourth support body 24. The fourth magnetic attraction member 54 is located at the connection between the fourth support body 24 and the first support body 21.

[0040] The cover 20 is designed as a ring or rectangular structure composed of multiple support bodies, with magnetic attachments installed between every two adjacent support bodies. This creates a multi-point uniform magnetic attraction between the cover 20 and the frame assembly 10. When the cover is closed, these four magnetic attachments adsorb onto the corresponding metal parts or magnetic mating parts of the frame assembly, achieving 360° circumferential magnetic fixation. This improves the stability and sealing performance of the cover 20 when closed. Every corner is firmly attracted, preventing dust and moisture from seeping in due to loosening in any part. This enhances the overall protective performance of the structure.

[0041] Reference Figures 1 to 5 In this embodiment of the utility model, the electrical box bracket structure further includes a gasket 60, which is located between the magnetic suction assembly 50 and the cover 20.

[0042] A gasket 60 is disposed between the magnetic absorbing assembly 50 and the cover 20 to form a buffer isolation layer between them. This gasket 60 not only reduces rigid contact wear between the magnetic absorbing assembly 50 and the cover 20, but also enhances the stability of the magnetic absorbing assembly 50 during installation and improves the sealing performance and electrical safety of the overall structure. In this embodiment, the gasket 60 can be a sponge.

[0043] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
