Description

Technical Field

[0001] This utility model relates to the field of wall-mounted distribution box technology, and more specifically, to a modular split wall-mounted distribution box. Background Technology

[0002] Currently, the widely used wall-mounted electrical distribution boxes in buildings generally adopt a structure that combines an integrally embedded box frame with internal functional units. This structure has significant shortcomings: First, the functional units are often tightly bound to the outer door panel. When the panel is opened for maintenance or repair, the small inner doors and inner protective panels used to protect specific areas immediately lose their protective function, failing to achieve true zoned isolation and protection, thus posing a safety hazard. Second, when it is necessary to add or replace functional units later, due to structural limitations, it is usually necessary to remove the entire panel along with the internal units. This is not only cumbersome to construct, but also renders the original small inner doors and inner protective panels unusable, wasting resources and affecting expansion flexibility.

[0003] Furthermore, the production and on-site installation processes of existing distribution boxes are highly coupled, making it difficult to achieve independent manufacturing and step-by-step construction of the frame, functional units, and panels. This results in low on-site installation efficiency, especially when wall construction and electrical installation are not synchronized. The functional units and panels embedded in the frame are easily contaminated or damaged. At the same time, this integrated structure severely restricts the feasibility of dynamically adjusting the internal configuration of the box according to needs later. Therefore, in order to address the above technical problems, a modular split-type wall-mounted distribution box is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a modular split-type wall-mounted distribution box. The pre-embedded frame is installed independently in the wall first, the functional unit has an adjustable small door and a protective plate to form an independent protective area, and the split panel is assembled last. The three can be manufactured separately and constructed in stages. When expanding, only the corresponding functional units and panel modules are added or deleted without interfering with the existing structure, so as to realize dynamic expansion and precise maintenance.

[0005] This utility model is achieved through the following technical solution:

[0006] A modular, split-type wall-mounted distribution box includes a split-type mounting panel, functional units, and a pre-embedded box frame. The split-type mounting panel consists of a protective door and a door frame. One side of the door frame is fixedly connected to a mounting lug, and an adjustable mounting hole is provided on the outside of the mounting lug. The lower side of the pre-embedded box frame has inlet and outlet holes. The main body of the functional unit is composed of a unit frame body. Component mounting plates are fixedly connected to both sides of the unit frame body. A small inner door is rotatably connected to the inner side of the unit frame body, and an inner protective plate is fixedly connected to the inner side of the unit frame body.

[0007] Preferably, the protective door is fixedly connected to the outside with a door handle.

[0008] Preferably, the external threaded connection of the pre-embedded box frame is provided with mounting bolts.

[0009] Preferably, the main body of the unit frame has unit frame mounting holes and adjustable panel mounting holes on its exterior.

[0010] Preferably, the number of mounting holes in the unit frame and the adjustable mounting holes in the panel are several groups arranged symmetrically.

[0011] The technical solution of this utility model has at least the following beneficial effects:

[0012] This utility model proposes a modular, split-type wall-mounted distribution box. By designing the pre-embedded frame, functional units, and panels as independent modules, it achieves phased construction and flexible adjustment. The pre-embedded frame can be installed in the wall first, and the functional units and panels can be assembled later as needed, avoiding mutual interference during the installation of traditional distribution boxes. Secondly, each functional unit has its own independent small inner door and inner protective panel. During maintenance or expansion, only the specific unit needs to be operated without affecting the protective functions of other areas, which improves safety and reduces resource waste. Finally, with the modular design, later expansion or renovation only requires adding or removing the corresponding functional units and panels, without the need for overall demolition, significantly improving construction efficiency and renovation flexibility, while reducing maintenance costs. This design is particularly suitable for building electrical engineering projects that require frequent adjustments or phased construction. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6 This utility model proposes a modular split-type wall-mounted distribution box, including a split-type mounting panel 1, a functional unit 2, and a pre-embedded box frame 3. The split-type mounting panel 1 consists of a protective door 4 and a door frame 5. A mounting ear 6 is fixedly connected to one side of the door frame 5. An adjustable mounting hole 7 is opened on the outside of the mounting ear 6. An inlet / outlet hole 10 is opened on the lower side of the pre-embedded box frame 3. The main body of the functional unit 2 is composed of a unit frame body 11. Component mounting plates 12 are fixedly connected to both sides of the unit frame body 11. A small inner door 15 is rotatably connected to the inner side of the unit frame body 11. An inner protective plate 16 is fixedly connected to the inner side of the unit frame body 11.

[0022] The protective door 4 is externally fixedly connected with a door handle 8, and the pre-embedded box frame 3 is externally threadedly connected with mounting bolts 9.

[0023] The main body 11 of the unit frame has unit frame mounting holes 13 and adjustable panel mounting holes 14 on its exterior. There are several sets of unit frame mounting holes 13 and adjustable panel mounting holes 14, which are arranged symmetrically.

[0024] The working principle of a modular, split-type wall-mounted distribution box based on an embodiment is as follows: This modular, split-type wall-mounted distribution box operates based on its three-level modular structure and step-by-step installation design, achieving efficient construction, dynamic expansion, and comprehensive protection. Its core workflow is as follows:

[0025] The pre-embedded box frame 3 serves as the basic structure. During the wall construction phase, it is independently embedded into the wall hole. The pre-set functional unit 2 mounting bolts 9 and upper and lower inlet and outlet holes 10 inside provide physical interfaces for subsequent installation. After the frame is fixed with quick-drying cement, it forms a stable installation base and pre-embeds wiring pipes to prepare for electrical connection. This stage only involves the frame body and does not require consideration of the assembly of functional unit 2 and panel.

[0026] Modular functional unit 2, as the electrical core, is installed independently after the frame is fixed. The main body of functional unit 2—the unit frame body 11—has its own component mounting plate 12, realizing the modular integration of electrical components. The small inner doors 15 and inner protective plates 16 fixed on both sides form a closed protective unit. The depth can be flexibly adjusted according to the internal components. During installation, the unit is embedded into the pre-embedded frame and fastened by the bolts and nuts reserved in the frame. The key point is that the small inner doors 15 and inner protective plates 16 are always installed or removed synchronously with functional unit 2, ensuring that the internal protective structure is always independent and effective when operating any unit, avoiding the problem of lack of protection when expanding the capacity of traditional enclosures.

[0027] The split-type mounting panel 1 is assembled last, completing the external encapsulation and user interaction. The panel consists of a door frame 5 and a hinged protective door 4. The mounting ears 6 on both sides of the door frame 5 are connected to the side frame of the functional unit 2 through adjustable mounting holes 7, and the horizontal adjustment is achieved by bolts to adapt to uneven wall surfaces. The protective door 4 is opened and closed by an external door handle 8. The independent installation mechanism of the panel ensures that its disassembly and assembly do not affect the internal functional unit 2 and protective structure, facilitating local maintenance or replacement.

[0028] The expansion and maintenance mechanism embodies the core advantages: when capacity needs to be increased, only a new functional unit 2 needs to be added within the pre-embedded frame, and its built-in small inner door 15 / inner protective plate 16 immediately forms an independent protection zone; after the new unit is installed, only the panel frame module of the corresponding area needs to be adjusted or replaced, without the need for complete dismantling. Similarly, maintenance of any functional unit 2 (such as a circuit breaker module) only requires disassembling the unit and its corresponding panel, without affecting the operation of adjacent units.

[0029] In summary, this design, through a three-level separation architecture of pre-embedded frame fixed base, independent integrated protection of functional unit 2, and flexible panel adaptation and encapsulation, combined with adjustable mounting holes 7 and modular interfaces, realizes the core working principle of decoupling installation process, binding protection unit to functional module, and precise positioning for expansion and maintenance, and completely solves the problems of step-by-step installation lack of protection, poor expandability and low construction efficiency of traditional distribution boxes.
