[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] See also Figures 1 to 8As shown, the present invention provides a distribution box, including a box body 1, in which an adjustment component and a supporting member 3 are provided. The supporting member 3 divides the box body 1 into at least two installation spaces. The adjustment component can adjust the height position of the supporting member 3 in the box body 1 to adjust the size of the installation space.

[0030] In the above technical solution, the enclosure 1 houses electrical equipment and its wiring, while also providing a mounting base for components such as the adjustment assembly and support member 3. The adjustment assembly powers the lifting and lowering motion of support member 3, which, within enclosure 1, primarily supports electrical equipment such as switches, providing a reliable mounting platform. Support member 3 divides enclosure 1 into at least two mounting spaces. When support member 3 carries fewer devices or a smaller device, the adjustment assembly drives support member 3 upward, freeing up space beneath support member 3 for mounting other electrical equipment.

[0031] The distribution box provided by the present invention is equipped with an adjustment component that cooperates with the supporting member 3, so that the supporting member 3 can move up and down in the distribution box according to the size and number of equipment carried thereon, and flexibly adjust the ratio of the upper and lower installation spaces of the supporting member 3, thereby improving the adaptability and flexibility of the spatial layout of the distribution box and significantly reducing space waste.

[0032] In one embodiment of the present invention, the adjustment assembly includes a telescopic rod 21, a support portion 11 is provided in the box body 1, one end of the telescopic rod 21 is connected to the top plate of the box body 1, and the other end is connected to the support portion 11, and the supporting member 3 is provided on the support portion 11. The telescopic rod 21 can drive the support portion 11 to move up and down.

[0033] In the above technical solution, the telescopic rod 21 connects the top plate of the box body 1 and the support part 11, and the telescopic rod 21 is driven by a driving device such as a motor, a hydraulic cylinder, or a pneumatic cylinder to perform telescopic movement, so that the support part 11 and the supporting member 3 thereon can be raised and lowered in the box body 1, thereby providing the distribution box with the ability to dynamically adjust the spatial layout, improving the flexibility and adaptability of the distribution box, optimizing the layout of the equipment, and improving space utilization.

[0034] In one embodiment of the present invention, the supporting member 3 includes a sliding tray 32 . The sliding tray 32 includes a mounting seat 321 and a tray 322 . The mounting seat 321 is disposed on the support portion 11 , and the tray 322 is slidably disposed on the mounting seat 321 .

[0035] In the above technical solution, the sliding tray 32 comprises a mounting base 321 and a tray 322. The mounting base 321 is fixed to the support portion 11, providing a stable mounting base and accurate sliding guide for the tray 322. The combination of the mounting base 321 and the support portion 11 ensures the stability and safety of the sliding tray 32 during lifting or sliding adjustment, preventing accidental shaking or falling of the equipment during movement. The tray 322 is the load-bearing portion of the sliding tray 32 and is directly used to place and secure various devices, such as switches and power modules. A sliding connection is designed between its bottom and the mounting base 321, allowing the tray 322 to slide back and forth, allowing electrical equipment to be flexibly extended and retracted. Using the sliding tray 32 as the support member 3 to support electrical equipment such as switches, during installation, disassembly, and maintenance, the electrical equipment can be extended from the enclosure by simply pulling out the sliding tray 32. This provides operators with a larger space for equipment maintenance, improving convenience.

[0036] In one embodiment of the present invention, the sliding tray 32 is made of carbon structural steel, the sliding rail on the mounting seat 321 is 200 mm long, the sliding rail is 45 mm wide, and the withdrawable length is 200 mm. When fully extended, the total length of the sliding tray 32 is 400 mm, and an anti-collision rubber pad is provided at the end of the sliding rail.

[0037] In the above technical solution, carbon structural steel offers excellent strength and rigidity, while also being low-cost and easy to process. Choosing this material for the sliding tray 32 ensures that the tray remains stable and resists deformation even when supporting equipment of a certain weight, while also facilitating manufacturing and maintenance. The slide rail dimensions are designed with practical needs and ease of use in mind. The 200mm slide rail length ensures sufficient space for equipment to be pulled out for easy maintenance and inspection, while the 45mm width provides ample lateral support to prevent equipment from shaking during sliding, enhancing stability. The sliding tray 32 can be pulled out 200mm, and its total length when fully extended is 400mm. This design allows maintenance personnel to fully pull the tray out of the enclosure, facilitating equipment installation, replacement, and cleaning without occupying excessive external space. Anti-collision pads are located at the ends of the slide rails to reduce the impact of the tray against the enclosure during closing, effectively reducing operating noise. The friction generated by the contact between the anti-collision pads and the tray 322 prevents the tray 322 from sliding out in the event of an accident, enhancing safety.

[0038] In one embodiment of the present invention, the support portion 11 is provided with wiring holes 5 , and a plurality of wiring holes 5 are arranged in an array on the support portion 11 .

[0039] In the above technical solution, by providing a branching hole 5 on the support portion 11, the power lines, signal lines and optical fiber lines can be effectively physically isolated and classified. At the same time, the branching holes 5 on the support portion 11 are connected to the installation spaces respectively located above and below the support portion 11, ensuring that the cables can pass through the support portion 11 and enter different installation spaces for signal or power transmission. Each cable can be led out through an independent branching hole 5 to avoid contact and entanglement between cables, thereby reducing electromagnetic interference and ensuring the communication quality and power supply stability of each system or device. The precise positioning and reasonable distribution of the branching holes 5 help to optimize the spatial layout inside the box 1. It not only ensures that the cables can be neatly led out from the support portion 11, but also provides the necessary space for the lifting and sliding of the support member 3, avoiding interference between the support member 3 and the cables during the lifting movement.

[0040] In one embodiment of the present invention, the mounting base 321 includes a first fixing plate 323 located on both sides of the mounting base 321, and a second fixing plate 324 is provided on both sides of the tray 322 corresponding to the first fixing plate 323. Fixing holes 325 are provided on the first fixing plate 323 and the second fixing plate 324. A fixing portion 326 is provided on the mounting base 321, and the fixing portion 326 can be snap-fitted with the fixing hole 325 to lock the relative position of the first fixing plate 323 and the second fixing plate 324.

[0041] In the above technical solution, the relative position between the first fixing plate 323 and the second fixing plate 324 is locked by the engagement of the fixing hole 325 and the fixing portion 326, so that the sliding tray 32 remains stable, ensuring that the sliding tray 32 remains stable during use or lifting, avoiding sliding of the tray 322 or displacement of the equipment due to uneven weight of the equipment or vibration during lifting and lowering, thereby protecting the equipment in the box from damage.

[0042] In one embodiment of the present invention, the adjustment assembly includes a driving device and a connecting rod 24. A slide rail 23 is provided on the connecting rod 24, and the slide rail 23 extends in a vertical direction. A slider is provided on the supporting member 3, and the slider is slidably connected to the slide rail 23. The driving device can drive the slider to move up and down along the slide rail 23.

[0043] In the above technical solution, the driving device usually includes an electric motor, a cylinder or a manual screw lifting mechanism, which is responsible for providing power for the slider to move up and down along the slide rail 23. The connecting rod 24 not only serves as a carrier for the slide rail 23, but also plays a role in connecting the top plate of the box body 1 and the supporting member 3. The slide rail 23 is arranged in the vertical direction on the connecting rod 24, providing guidance and constraints for the slider, ensuring the linearity and stability of the supporting member 3 in the up and down movement. Through the control of the driving device, the slider can perform precise lifting and lowering movements along the slide rail 23, thereby adjusting the position of the supporting member 3 inside the box body 1, so that maintenance personnel can adjust the internal space of the box body according to the equipment installation situation.

[0044] In one embodiment of the present invention, the adjustment assembly includes a connecting rod 24, one end of which is connected to the top plate of the box body 1, and a plurality of first mounting holes 25 are arranged at intervals on the connecting rod 24. A second mounting hole 26 is provided on the supporting member 3. The second mounting hole 26 is connected to the first mounting hole 25 by a bolt to lock the height position of the supporting member 3. The second mounting hole 26 can cooperate with different first mounting holes 25 to adjust the height position of the supporting member 3.

[0045] In the above technical solution, the connecting rod 24 is used to connect the top plate of the box body 1 and the supporting member 3. The multiple first mounting holes 25 arranged at intervals on the connecting rod 24 constitute the basis for height adjustment. Each hole position represents a specific height option. The user can select the appropriate hole position according to actual needs to adjust the height of the supporting member 3. By adjusting which first mounting hole 25 the second mounting hole 26 is aligned with and fixing it with bolts, the position of the supporting member 3 in the box body 1 can be flexibly changed to meet the installation height requirements of different equipment. Since the height of the supporting member 3 can be adjusted by selecting different first mounting holes 25, this means that in subsequent maintenance or when the equipment needs to be expanded, the height of the existing supporting member can be easily adjusted, or new supporting members can be added to adapt to the installation requirements of the newly added equipment, saving time and cost.

[0046] In one embodiment of the present invention, a mounting strip 4 is further provided in the box body 1 . The mounting strip 4 is provided on the inner wall of the box body 1 and can move up and down in the vertical direction.

[0047] In the above technical solution, the mounting bead 4 is used to secure electrical equipment such as optical modems and power conversion modules. By pressing the electrical equipment against the side walls of the box, the mounting bead 4 can be used to secure the electrical equipment. The mounting bead 4 can be raised and lowered vertically, allowing for more efficient space management within the box 1 and a rational layout of various types of equipment. By positioning the mounting bead 4 in the lower installation space and coordinating it with the height adjustment of the support member 3, the ratio of the upper and lower spaces, as well as the installation positions of the electrical equipment within each space, can be finely adjusted, thereby further improving space utilization.

[0048] In one embodiment of the present invention, at least one of the top plate and the bottom plate of the box body 1 is further provided with a wiring hole 5 , and a plurality of wiring holes 5 are arranged at intervals.

[0049] In the above technical solution, the cable breakout holes 5 on the distribution box connect the interior and exterior of the box, allowing cables to be routed from the box to external devices. Multiple, spaced-apart cable breakout holes 5 are primarily used to manage and categorize different types of cables, preventing crosstalk and confusion, and facilitating identification and maintenance. Furthermore, by physically isolating different types of cables, particularly separating power cables from signal cables and fiber optic cables, the impact of electromagnetic interference generated by power cables on other cables can be significantly reduced, ensuring clear and stable communication signals and improving overall system performance.

[0050] In one embodiment of the present invention, the interval between two adjacent branching holes 5 is 140 mm to 150 mm, and the diameter of the branching holes 5 is 4 mm to 50 mm.

[0051] In the above technical solution, the spacing of 140mm to 150mm can effectively reduce the possibility of electromagnetic interference between different cables, especially when power cables and other sensitive cables such as signal cables and optical fiber cables need to be led out of the box. The appropriate distance can significantly reduce electromagnetic interference and ensure communication quality. The diameter range is from 4mm to 50mm, which means that the branch hole 5 can accommodate cables of different diameters, such as thin signal cables and thicker power cables. This allows maintenance personnel or installers to select the appropriate branch hole for wiring according to the type and diameter of the cable, improves the versatility of the branch hole 5, and realizes the classification and physical isolation of cables.

[0052] In one embodiment of the present invention, a dust plug is provided on the branching hole 5 , which allows the cable to pass through and wraps the cable to prevent dust from entering the box 1 .

[0053] In the above technical solution, the dust plug fits tightly between the cable and the branch hole 5, forming a physical barrier that effectively prevents dust and impurities from entering the box, maintaining a clean environment inside the box and extending the service life of the device. While wrapping the cable, the dust plug also provides a certain degree of protection, preventing the cable from rubbing against the inner wall of the branch hole 5 when passing through the branch hole 5, causing wear or damage, thereby ensuring the integrity of the cable and the quality of signal transmission.

[0054] In one embodiment of the present invention, a detachable wire trough 6 is provided in the box 1, and the wire trough 6 includes a power wire trough and an optical fiber wire trough. One of the power wire trough and the optical fiber wire trough is provided on the side wall of the box 1, and the other is provided on the bottom plate of the box 1.

[0055] In the above technical solution, the cable trough 6 provides a dedicated channel for the cables, making the layout of the cables in the box 1 orderly and standardized. The presence of the power cable trough and the optical fiber cable trough ensures the reasonable separation of different cables and reduces the risk of signal interference. The location of the cable trough 6 allows maintenance personnel to locate the required cables more quickly and accurately when performing line inspections or equipment adjustments, reducing maintenance difficulty and time. By providing a detachable cable trough 6, the line layout has good compatibility and scalability, can adapt to the cable management of existing equipment, and also facilitates the addition of equipment and expansion of lines in the future, without limiting the use function of the box due to the fixed position of the cable trough.

[0056] In one embodiment of the present invention, the distribution box is further provided with first heat dissipation holes 7 , which are evenly distributed on both sides of the box body and include louver-type heat dissipation holes.

[0057] In the above technical solution, by evenly distributing the first cooling holes 7 on both sides of the box, natural convection air is generated, promoting the exhaust of hot air inside the box and introducing fresh air, achieving excellent heat dissipation. This eliminates the need for additional electric fans or air conditioning systems, reducing energy consumption and operating costs. The use of louvered cooling holes as the first cooling holes 7 maintains good ventilation while effectively blocking the intrusion of external dust and moisture, improving the equipment's protection level and the cleanliness of the operating environment.

[0058] In one embodiment of the present invention, the supporting member 3 is provided with second heat dissipation holes 8 , and a plurality of second heat dissipation holes 8 are arranged in a matrix on the supporting member 3 .

[0059] In the above technical solution, the support member 3 is generally used to carry and fix key electronic equipment such as switches and power conversion modules, which generate a large amount of heat during operation. By providing second heat dissipation holes 8 thereon, local heat dissipation around these devices can be enhanced in a targeted manner to prevent the equipment from overheating. The second heat dissipation holes 8 arranged in a matrix can ensure uniform air circulation on the surface of the support member 3, thereby improving heat dissipation efficiency. Compared with active heat dissipation systems such as fans, the naturally ventilated second heat dissipation holes 8 can achieve heat dissipation purposes with lower energy consumption and lower noise, creating a more environmentally friendly and quiet communication room environment.

[0060] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: the box body 1 is used to accommodate electrical equipment and its circuits, and at the same time provides an installation base for components such as the adjustment assembly and the support member 3. The adjustment assembly is used to provide power for the lifting movement of the support member 3. The support member 3 is mainly used to support electrical equipment such as switches in the box body 1, providing a reliable installation platform for the electrical equipment. The support member 3 divides the box body 1 into at least two installation spaces. When the support member 3 carries fewer devices or the height of the carried devices is small, the adjustment assembly drives the support member 3 to rise, thereby making more space below the support member 3 for installing other electrical equipment. The distribution box provided by the present invention, by providing an adjustment assembly to cooperate with the support member 3, enables the support member 3 to move up and down in the distribution box according to the size and number of the equipment carried on it, flexibly adjusts the ratio of the upper and lower installation spaces of the support member 3, improves the adaptability and flexibility of the distribution box space layout, and significantly reduces space waste.
