Description

Technical Field

[0001] This utility model relates to the field of distribution boxes, and in particular to a compact wall-mounted distribution box. Background Technology

[0002] As the core device for power distribution, line protection and equipment control in low-voltage power distribution systems, distribution boxes are widely used in various places such as residential buildings, commercial buildings, industrial plants and public facilities. With the increasingly compact space in modern buildings, especially in space-constrained areas such as apartments, corridors, stairwells and equipment rooms, higher requirements are placed on the miniaturization, efficiency and flexible installation of power distribution equipment.

[0003] Traditional distribution boxes mostly adopt vertical or embedded structures, which are usually large in size and require independent installation space or wall grooves. This not only occupies valuable building area but also increases the difficulty of civil construction and installation time. In addition, the unreasonable internal structure design of some distribution boxes further exacerbates the problem of wasted space. The mounting rails or brackets for internal components such as circuit breakers are mostly fixed in layout, and the arrangement lacks compactness. This causes the depth or height of the box to exceed the actual needs, often resulting in a "top-heavy" appearance, underutilization of vertical space, or empty areas in the middle. It is difficult to meet the application needs of small spaces, low headroom environments, or wall-mounted installation conditions.

[0004] Therefore, a compact wall-mounted distribution box needs to be designed. Utility Model Content

[0005] To overcome the shortcomings of traditional distribution boxes, such as large footprint and loose internal layout, this utility model provides a compact wall-mounted distribution box.

[0006] The technical solution is as follows: A compact wall-mounted distribution box includes a distribution box body, a cabinet door, a handle, a first bolt, a mounting plate, a lifting plate, guide blocks, mounting plates, a second bolt, and a terminal block. The distribution box body has multiple inlet and outlet holes on its upper and lower sides. A rotating cabinet door is located on the front of the distribution box body, with a handle on the left side of the door. The left side of the cabinet door is threadedly connected to the distribution box body by a first bolt. Two mounting plates are fixed to both the left and right sides of the distribution box body. A lifting plate is fixed to the top rear side of the distribution box body. Guide blocks are installed on both the left and right sides inside the distribution box body, and these guide blocks are arranged vertically. Each guide block has multiple equally spaced threaded slots. Multiple mounting plates are located between two guide blocks, and the mounting plates are threadedly connected to the guide blocks by the second bolt. A terminal block is installed on the lower side inside the distribution box body.

[0007] As an improvement to the above solution, it also includes a connecting rod and cable management clips. The connecting rod is fixedly connected to the lower part of the distribution box. The connecting rod is located above the terminal block. Multiple cable management clips are slidably provided on the rear side of the connecting rod. The cable management clips are located below the mounting plate.

[0008] As an improvement to the above solution, it also includes cooling fans and warning signs. Two cooling fans are installed inside the rear of the distribution box, and a warning sign is provided in the middle of the front side of the cabinet door.

[0009] As an improvement to the above solution, rubber gaskets are also included, with rubber gaskets installed inside the inlet and outlet holes of the distribution box.

[0010] As an improvement to the above solution, multiple ventilation holes are provided at the bottom of the cabinet door.

[0011] As an improvement to the above solution, the overall thickness of the distribution box should not exceed 120 mm.

[0012] Beneficial effects:

[0013] 1. This utility model adopts a vertically arranged guide block and adjustable mounting plate structure. The electrical components can be freely adjusted in the vertical direction as needed to achieve a compact arrangement, avoid waste of vertical space, and improve the utilization rate of the internal space of the box.

[0014] 2. This utility model significantly reduces the space occupied by the equipment by designing the distribution box as an ultra-thin structure with an overall thickness of no more than 120 mm. At the same time, it supports both wall-mounted and suspended installation methods through the mounting holes on the left and right sides and the hanging holes on the top. The installation is flexible, adaptable to various site conditions, and reduces civil construction costs and installation cycle. Attached Figure Description

[0020] Example: A compact wall-mounted distribution box, such as Figure 1 , Figure 2 and Figure 4 As shown, the distribution box includes a distribution box body 1, a cabinet door 2, a handle 3, a first bolt 4, a mounting hole plate 5, a lifting hole plate 6, a guide block 7, a mounting plate 8, a second bolt 9, and a terminal block 10. The overall thickness of the distribution box body 1 does not exceed 120 mm. The distribution box body 1 has multiple inlet and outlet holes on its upper and lower sides. The front of the distribution box body 1 has a rotating cabinet door 2. A handle 3 is installed on the left side of the cabinet door 2. The left side of the cabinet door 2 is threadedly connected to the distribution box body 1 by a first bolt 4. Two mounting hole plates 5 are fixed to both the left and right sides of the distribution box body 1. A lifting hole plate 6 is fixed to the top and rear side of the distribution box body 1. Guide blocks 7 are installed on both the left and right sides inside the distribution box body 1. The guide blocks 7 are arranged vertically and have multiple equally spaced threaded slots. Multiple mounting plates 8 are provided between two guide blocks 7, and the mounting plates 8 are threadedly connected to the guide blocks 7 by second bolts 9. A terminal block 10 is installed on the lower side inside the distribution box body 1.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, it also includes a connecting rod 11 and a cable management clamp 12. The connecting rod 11 is fixedly connected to the lower part of the distribution box 1. The connecting rod 11 is located above the terminal block 10. Multiple cable management clamps 12 are slidably provided on the rear side of the connecting rod 11. The cable management clamps 12 are located below the mounting plate 8.

[0022] like Figure 1 and Figure 4 As shown, it also includes a cooling fan 13 and a warning sign 14. Two cooling fans 13 are installed inside the rear side of the distribution box 1, and a warning sign 14 is provided in the middle of the front side of the cabinet door 2.

[0023] like Figure 1 and Figure 2 As shown, it also includes rubber gaskets 101. The inlet and outlet holes on the distribution box 1 are equipped with rubber gaskets 101, which effectively protect the cable insulation layer, prevent wear and leakage, and at the same time have dustproof, moisture-proof and sealing functions, improving the safety of equipment operation and environmental adaptability.

[0024] like Figure 1As shown, the lower part of the cabinet door 2 has multiple ventilation holes, which together with the cooling fan 13 form an efficient air convection channel to promptly dissipate heat from the cabinet, prevent components from aging or malfunctioning due to excessive temperature rise, and ensure long-term stable operation of the system.

[0025] In actual use, the user fixes the distribution box 1 to the wall using multiple mounting holes 5 on the left and right sides and expansion bolts. Alternatively, it can be suspended using the hanging holes 6 on the rear top of the box. This allows for ceiling or high-altitude installations, adapting to different site conditions. The cabinet door 2 is connected to the front of the distribution box 1 via hinges. After closing, it is locked to the distribution box 1 by the first bolt 4 to ensure safe operation. The left side of the cabinet door 2 has a handle 3 for easy opening and maintenance. Multiple ventilation holes are provided at the bottom of the cabinet door 2, which, together with the two cooling fans 13 installed on the rear side inside the distribution box 1, form a front-to-back convection cooling duct, effectively reducing the temperature inside the box and ensuring the stable operation of components such as circuit breakers and contactors.

[0026] When installing electronic components, users can adjust the height of the mounting plate 8 vertically in the guide block 7 according to the actual component size and installation requirements, and lock it in the corresponding threaded slot with the second bolt 9. This allows for flexible configuration of the installation height of electrical components such as circuit breakers, relays, and contactors, avoiding the space waste caused by traditional fixed guide rails and maximizing the use of the vertical space inside the enclosure. In addition, if users have expansion or function adjustment needs in the future, they only need to loosen the second bolt 9 and move the mounting plate 8 located below upwards to reserve sufficient installation space at the bottom of the enclosure without replacing the enclosure, making maintenance more convenient.

[0027] The lower side of the inside of the distribution box 1 is equipped with a terminal block 10 for centralized connection of incoming and outgoing cables. To facilitate cable management, a connecting rod 11 is provided above the terminal block 10, and multiple cable clips 12 are slidably installed on the rear side. The position can be freely adjusted according to the number and direction of the cables to achieve orderly grouping and fixing of multiple wires, prevent tangling and crossing, and improve wiring standardization and maintenance efficiency. Furthermore, the incoming and outgoing cables are introduced and led out through the inlet and outlet holes on the upper and lower sides of the distribution box 1. Each hole is equipped with a rubber gasket 101, which can protect the cable sheath from scratches by the metal edge and also play a role in sealing, dustproofing and moisture-proofing, thereby improving the protection level. In addition, a warning sign 14 is provided in the middle of the front side of the cabinet door 2 to indicate the safety information of "high voltage danger" and "do not touch", enhance the safety awareness of non-operators, and comply with the requirements of electrical equipment safety specifications.
