Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical equipment installation technology, and in particular to an assembled distribution box device. Background Technology
[0002] Distribution boxes are enclosed or semi-enclosed metal cabinets in power systems used to centrally install switching equipment, measuring instruments, protective electrical appliances, and auxiliary components. Their core function is to distribute, monitor, control, and protect low-voltage circuits. As a key component of building electrical, industrial automation, and infrastructure power supply systems, distribution boxes not only ensure the safe operation of internal components but also directly affect the stability and reliability of the entire power system.
[0003] Chinese utility model patent CN220022019U discloses a modular distribution box device. It achieves convenient assembly, disassembly, and transportation of individual boxes through structures such as connecting rings, connecting grooves, and fixing blocks and grooves, and enhances local stability with the help of rubber rings. However, this solution does not provide an effective lateral or longitudinal assembly connection structure between multiple distribution boxes. This results in each box being independent and lacking overall coordination when multiple similar distribution boxes are installed side-by-side or transported together. This makes them highly susceptible to relative displacement or even tipping due to external vibrations, handling bumps, or uneven ground. Utility Model Content
[0004] The purpose of this invention is to provide a modular distribution box device that solves the problem that existing solutions do not have an effective horizontal or vertical assembly connection structure between multiple distribution boxes. This results in each box being independent and lacking overall linkage when multiple similar distribution boxes are installed side by side or transported together, making them prone to relative displacement or even tipping over due to external vibration, handling bumps, or uneven ground.
[0005] To achieve the above objectives, this utility model provides an assembled distribution box device, comprising several distribution boxes. Each distribution box has two docking plates on one side and two mounting cylinders on the other side, each corresponding to a docking plate. The top and bottom ends of the docking plates are connected to limit cylinders. An entry groove is formed on one side of each limit cylinder. Sliding grooves are formed at both ends of each mounting cylinder. A sliding rod is slidably connected inside each sliding groove. One end of the sliding rod is connected to the inner bottom of the sliding groove through an elastic structure, and the other end is connected to a docking block. A bevel is formed on one side of each docking block.
[0006] A fixing plate is connected between the two docking plates, and the fixing plate is bolted to the side wall of the distribution box.
[0007] The mounting cylinder has side grooves at the top and bottom of both sides that communicate with the interior of the sliding groove. A pressing rod is slidably connected inside the side groove, and one end of the pressing rod is connected to an adjacent sliding rod.
[0008] The two mounting cylinders are connected by a mounting plate. A mating sleeve is fixedly connected to the center of one side of the mounting plate, and a mating post adapted to the mating sleeve is fixedly connected to the center of one side of the fixing plate.
[0009] The limiting cylinder has an inclined surface one on one side that matches the inclined surface two, and the internal dimension of the limiting cylinder is larger than the dimension of the docking block.
[0010] The elastic structure includes a return spring, one end of which is connected to the end of the sliding rod, and the other end is connected to the inner wall of the sliding groove.
[0011] This utility model discloses a modular distribution box device. By setting docking plates and mounting cylinders on both sides of each distribution box, and cooperating with limiting cylinders, entry grooves, sliding grooves, sliding rods, elastic structures, and docking blocks with inclined surfaces to form a self-locking quick-assembly mechanism, it realizes a quick and stable mechanical connection between adjacent distribution boxes, significantly improving the overall rigidity and anti-overturning ability of the multi-box assembly. During transportation or on-site installation, the assembled distribution box group forms a unified force-bearing unit, effectively resisting external forces such as vibration, bumps, or uneven ground, preventing box slippage, collision, or overturning, thereby protecting the safety of internal electrical components and avoiding the risk of loose wiring or short circuits caused by box deformation.

Detailed Implementation
[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] Example 1 Please see Figure 1-5 As shown, an assembly-type distribution box device in this embodiment includes several distribution boxes 1. Each distribution box 1 has two docking plates 2 on one side and two mounting cylinders 3 on the other side, with positions corresponding to the docking plates 2. The top and bottom ends of the docking plates 2 are connected to limit cylinders 8. An entry groove 6 is opened on one side of the limit cylinder 8. Sliding grooves 12 are opened at both ends of the mounting cylinders 3. A sliding rod 17 is slidably connected inside each sliding groove 12. One end of the sliding rod 17 is connected to the inner bottom of the sliding groove 12 through an elastic structure, and the other end is connected to a docking block 9. An inclined surface 14 is opened on one side of the docking block 9.
[0021] When using this modular distribution box equipment, the operator assembles two adjacent distribution boxes 1, aligning two mating plates 2 on one side of one distribution box 1 with the corresponding mounting cylinders 3 on the other distribution box 1. Then, the two distribution boxes 1 are pushed closer together, causing the mating plates 2 to insert into the corresponding mounting cylinders 3. During this process, the limiting cylinders 8 connected to the top and bottom of the mating plates 2 enter the sliding groove 12 area at both ends of the mounting cylinder 3. The entry groove 6 on one side of the limiting cylinder 8 contacts the mating block 9 within the sliding groove 12. Because one side of the mating block 9 has a second inclined surface 14, as the limiting cylinder 8 continues to advance, the second inclined surface 14 is squeezed by the outer wall of the limiting cylinder 8, causing the mating block 9 to move into the sliding groove 12, thereby pushing the mating plate 9 into the sliding groove 12. The connecting sliding rod 17 compresses the elastic structure, causing the docking block 9 to temporarily retract. When the limiting cylinder 8 fully enters the sliding groove 12, the entry groove 6 is just aligned with the docking block 9. At this time, the elastic structure releases its elastic force, pushing the sliding rod 17 to reset outward, so that the docking block 9 is embedded in the entry groove 6, thereby locking the limiting cylinder 8 in the mounting cylinder 3, achieving a firm connection between the two distribution boxes 1. Multiple distribution boxes 1 can be assembled into a whole structure in this way, forming a lateral linkage during transportation or installation, avoiding independent shaking. When disassembling, simply press the docking block 9 to overcome the resistance of the elastic structure and make it disengage from the entry groove 6, and the adjacent distribution boxes 1 can be easily separated. The entire assembly process does not require additional bolts or tools, and the operation is simple and the connection is reliable.
[0022] Example 2 Please see Figure 1-5 As shown in this embodiment, a modular distribution box device has a fixing plate 4 connecting the two docking plates 2. The fixing plate 4 is bolted to the side wall of the distribution box 1. Specifically, by connecting the two docking plates 2 with the fixing plate 4 and bolting the fixing plate 4 to the side wall of the distribution box 1, the two docking plates 2 form an integral support structure under stress by the fixing plate 4, avoiding deformation or loosening of a single docking plate 2 due to local stress concentration. During the assembly process, the parallelism and positional stability of the docking plates 2 are maintained, thereby enhancing the rigidity of the docking structure, improving the reliability of the splicing, and enhancing the long-term durability.
[0023] A mounting plate 10 is connected between the two mounting cylinders 3. A mating sleeve 11 is fixedly connected to the center of one side of the mounting plate 10. A mating post 5 that matches the mating sleeve 11 is fixedly connected to the center of one side of the fixing plate 4. Specifically, by setting up a mounting plate 10 connecting the two mounting cylinders 3, a mating sleeve 11 fixedly connected to the center of one side of the mounting plate 10, and a mating post 5 fixedly connected to the center of one side of the fixing plate 4, when the two distribution boxes 1 are spliced, the mating post 5 is simultaneously inserted into the mating sleeve 11, forming a central positioning and auxiliary load-bearing structure. This not only guides the mating plate 2 and the mounting cylinder 3 to be accurately aligned, but also shares part of the lateral load, thereby improving the assembly accuracy, enhancing the overall connection strength, and preventing misalignment and displacement.
[0024] Example 3 Please see Figure 1-5 As shown in this embodiment, a modular distribution box device has side grooves 13 on both sides of the top and bottom of the mounting cylinder 3, which communicate with the interior of the sliding groove 12. A pressing rod 16 is slidably connected inside the side groove 13, and one end of the pressing rod 16 is connected to the adjacent sliding rod 17. Specifically, by setting up side grooves 13 on both sides of the mounting cylinder 3, which communicate with the interior of the sliding groove 12, and a pressing rod 16 slidably connected inside the side groove 13, with one end of the pressing rod 16 connected to the adjacent sliding rod 17, the operator can press the pressing rod 16 from the outside of the distribution box 1 during disassembly. The pressing rod 16 pushes the sliding rod 17 to move inward against the resistance of the return spring 15, so that the docking block 9 disengages from the groove 6. Quick unlocking can be achieved without the aid of tools, achieving the effect of facilitating manual disassembly, improving maintenance convenience and operational safety.
[0025] One side of the limiting cylinder 8 is provided with an inclined surface 7 that is adapted to the inclined surface 14. The internal size of the limiting cylinder 8 is larger than the size of the docking block 9. Specifically, by providing an inclined surface 7 that is adapted to the inclined surface 14 on one side of the limiting cylinder 8 and setting the internal size of the limiting cylinder 8 to be larger than the size of the docking block 9, the inclined surface 7 and the inclined surface 14 cooperate with each other during the docking process, so that the limiting cylinder 8 can more smoothly squeeze the docking block 9 to retract when it is pushed forward. At the same time, sufficient space is reserved to ensure that the docking block 9 can be fully embedded into the groove 6, avoiding jamming or interference. This achieves the effects of optimizing assembly smoothness, improving the reliability of self-locking action, and reducing wear.
[0026] The elastic structure includes a return spring 15. One end of the return spring 15 is connected to the end of the sliding rod 17, and the other end is connected to the inner wall of the sliding groove 12. Specifically, by including the return spring 15 in the elastic structure, with one end of the return spring 15 connected to the end of the sliding rod 17 and the other end connected to the inner wall of the sliding groove 12, after the docking block 9 is pushed into the sliding groove 12 by the limiting cylinder 8, the return spring 15 provides a stable elastic force to automatically reset it and embed it into the groove 6 to achieve locking. When disassembling, it can be pressed and compressed to release it, thus achieving the effect of ensuring that the self-locking function is stable and reliable, responsive, and does not fail during long-term use.
[0027] When using this modular distribution box equipment, the operator connects two adjacent distribution boxes 1. Two docking plates 2 on one side of one distribution box 1 are aligned with two mounting cylinders 3 on the corresponding side of the other distribution box 1. The two docking plates 2 are connected as one unit by a fixing plate 4, which is bolted to the side wall of the distribution box 1 to ensure the overall rigidity of the docking plates 2. Simultaneously, the two mounting cylinders 3 are connected by a mounting plate 10. A docking sleeve 11 is located at the center of the mounting plate 10, while a matching docking post 5 is located at the center of the fixing plate 4. When the two distribution boxes 1 approach each other, the docking post 5 first inserts into the docking sleeve 11 for initial positioning and center guidance. Then, the docking plate 2 enters the mounting cylinder 3, and the limiting cylinders 8 connected to its top and bottom slide into the sliding grooves 12 at both ends of the mounting cylinder 3. One side of the limiting cylinder 8 has an inclined surface 7 and an entry groove 6, while the sliding groove 12 contains a sliding rod 17. One end of the sliding rod 17 is connected to the docking block 9, and the other... One end is connected to the inner wall of the sliding groove 12 via a return spring 15. The outer side of the docking block 9 is provided with a second inclined surface 14 that matches the first inclined surface 7. During the pushing process, the first inclined surface 7 and the second inclined surface 14 contact and squeeze each other, causing the docking block 9 to drive the sliding rod 17 to overcome the elastic force of the return spring 15 and retract into the sliding groove 12. When the limiting cylinder 8 is fully in place, the inlet groove 6 is just aligned with the docking block 9. The return spring 15 pushes the sliding rod 17 to reset, so that the docking block 9 is embedded in the inlet groove 6 to achieve self-locking. At this time, the limiting cylinder 8 is firmly locked in the mounting cylinder 3, and because the internal size of the limiting cylinder 8 is larger than the size of the docking block 9, it ensures smooth embedding without interference. If disassembly is required, the operator can press the pressing rod 16 from the outside of the distribution box 1 through the side groove 13. The pressing rod 16 is connected to the sliding rod 17, pushing the docking block 9 out of the inlet groove 6, so that the two distribution boxes 1 can be easily separated. The entire assembly process does not require bolts or tools, and relies on mechanical self-locking and elastic reset to achieve quick connection and disassembly.
[0028] This modular distribution box system, through the coordinated operation of all the aforementioned structures, systematically solves the problem of displacement, tipping, and even damage during transportation or installation caused by the independent placement of multiple distribution boxes and the lack of an effective assembly structure in existing technologies. Specifically, the integrated design of the fixing plate 4 and the docking plate 2 improves the uniformity of force distribution and structural stability; the docking column 5 and the docking sleeve 11 form a central positioning pair, guiding precise alignment and sharing the lateral load; the inclined surface 7 on the limiting cylinder 8 cooperates with the inclined surface 14 on the docking block 9 to achieve smooth entry, entering the groove 6 and forming a reliable lock with the docking block 9; the return spring 15 provides stable elasticity to ensure sensitive and reliable self-locking action; the sliding rod 17 guides the movement within the sliding groove 12 to ensure the linear movement of the docking block 9; the side groove 13 and the pressing rod 16 allow disassembly to be completed outside the box without removing the cover or using tools.
[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
