[0002] In power supply systems, distribution boxes are the control centers that direct the rational allocation of electrical energy among various components in power supply lines. They are the control links that reliably receive power from upstream sources and correctly feed out load power. They are used for the rational allocation of electrical energy, facilitate the opening and closing of circuits, have a high level of safety protection, and can intuitively display the conduction status of circuits. A Chinese patent discloses a distribution box that is easy to install, application number: CN202421007016.0. It uses lifting wheels to raise and lower the lifting plate used to support the distribution box, so that when the distribution box needs to be inspected or installed, the operation is simple and quick. However, current distribution boxes not only fail to effectively accommodate the size deviations of electronic components and have low space utilization, resulting in unnecessary redundant volume, but also require staff to adjust, inspect, and maintain the electronic components inside the box due to cable constraints. This not only affects operational convenience but also compromises safety. Furthermore, the cables cannot be effectively managed, easily becoming tangled and affecting safety, or easily loosened and detached due to pulling, affecting operational stability.

[0014] Compared with the prior art, the advantages of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use; 1. Equipped with a partitioning guide mechanism, which uses screws, corner blocks, threaded rings, slide rods, spacers, and extension plates to form a dynamic partitioning structure, it not only enables flexible partitioning of the internal space of the distribution box, but also allows for stepless adjustment of the gaps between spacers according to the actual size of the installed electronic components. This significantly improves the compatibility and adaptability of the distribution box and electronic components, maximizing the utilization of the internal space of the box frame. It effectively reduces the ineffective redundant space generated inside the distribution box during the installation of electronic components, allowing the distribution box to accommodate the same number and size of electronic components in a smaller volume, effectively optimizing the space ratio of the distribution box, and making the use and installation of the distribution box more flexible and convenient. In addition, the limiting effect of guide rods, caps, clamps, compression springs, and threaded rings not only effectively improves the stability and convenience of the partitioning work, but also can be used with tension springs and bolts to facilitate the dynamic storage and installation of electronic components. During use, electronic components can be easily put into and taken out of the distribution box, simultaneously improving the convenience and safety of electronic component control, inspection, and maintenance. Equipped with perforated plates, angle rollers, vertical rods, suspension seats, compression springs, horizontal rods, sliders, suspension rollers, threaded rings, and springs for limiting and guiding, a dynamic constraint structure can be formed to achieve flexible cable storage. This not only removes the restriction of cables on electronic components and compensates for cable length deviations caused by displacement during the removal of the spacer, but also allows electronic components to be freely removed from the distribution box during use. This enables external control and maintenance without affecting the connection stability and continuous operation of electronic components. Furthermore, it provides dynamic cable limiting, ensuring that the cables remain taut during the control and maintenance of electronic components, preventing tangling and disarray during component displacement. It also actively releases the bundled cables when subjected to external disturbances. Combined with the limiting effect of air cushions, it effectively prevents cable connections from loosening and falling off due to external pulling, ensuring operational stability and safety. With the guiding effect of guide rings and ball bearings, it effectively reduces the friction of the cables during displacement compensation, making the flexible storage operation smoother and reducing cable wear.

[0015] 2. Equipped with a composite locking mechanism, the enclosure can be modularly assembled using a combination of grid plates, pads, guards, top cover, base, rear seat, and junction box. This allows for dynamic limit maintenance of the enclosure frame and more flexible combination of frames. It enables free assembly of single-frame, double-frame, and even multi-frame enclosures according to actual needs, facilitating convenient, efficient, and stable expansion and control of the overall capacity of the distribution box. This meets the diverse capacity requirements of different power supply and distribution operations. The sealing plate's limiting and blocking function isolates the enclosure frame, ensuring its relative independence while allowing unimpeded flow between frames for overall linkage. This makes the internal space of the distribution box more diverse and richer in its functional zoning. Combined with a zoning guide mechanism to partition the internal space of the enclosure frame, it can more fully and efficiently meet the space requirements of electronic components, expanding the effective adaptability of the distribution box. By combining the base pad, plug plate, and bottom cavity, a gravity conversion and elastic buffer structure can be constructed. Combined with the limiting and locking effects of the insertion rod, return spring, push plate, horizontal cavity, connecting hole, socket, vertical box, support rod, sliding plug, threaded cylinder, connecting rod, pin, piston, and ear plate, gravity can be transformed into connection stress between the components of the distribution box, synchronously limiting and fixing each component, achieving interlocking of limit positions between components. This not only effectively improves the overall stability and force balance of the distribution box, but also further disperses and transforms disturbance forces such as ground vibrations during the use of the distribution box, expanding the force-bearing surface of the distribution box. It can also compensate for displacement caused by vibration, preventing loose connections, reducing disturbance impacts, improving the balance of the distribution box, and ensuring the stability of its internal electronic components and cable connections. Synchronous limiting can be achieved through the cooperation of bends, connecting valves, and conduits.

[0016] In summary, this distribution box not only provides stepless partitioning of its internal components, effectively accommodating dimensional deviations of electronic components, improving compatibility and space utilization, and optimizing space ratio, but also removes the constraints of cables on electronic components, achieving dynamic constraint on cables. This allows for external adjustment and maintenance of electronic components while preventing cables from becoming tangled and twisted, and avoiding rigid pulling on cables, thus ensuring connection stability and safety in maintenance and use. Furthermore, the overall capacity of the distribution box can be easily expanded, broadening its applicability. Gravity allows for dynamic interlocking between components, reducing vibration disturbances and ensuring the balance and stability of the distribution box. Attached Figure Description

[0022] The working principle and usage process of this invention: In actual use, this distribution box first selects the corresponding number of box frames 1 and partitions 205 according to actual needs, based on the number and size of the electronic components to be installed and the capacity of a single box frame 1, and matches the corresponding number of supporting components, and then assembles and installs them to form the main body of the distribution box. During the assembly and installation of the various components of the distribution box, the base 306 is first placed stably on the ground. After the rear seat 307 is engaged with the box frame 1, the box frame 1 is aligned with the base 306 and the box frame 1 is fitted onto the base 306. During this process, under the elastic compression of the return spring 313, the plug rod 311 will retract into the horizontal cavity 32. At this time, the rear seat 307 can be pressed down synchronously with the box frame 1. The bottom end of the rear seat 307 will also be embedded in the gap between the vertical box 314 and the base 306. Under the limiting action of the vertical box 314, the socket 34 will be aligned with the plug rod 311. Next, align the pad 303 with the box frame 1 and snap it into the box frame 1. Then, selective installation can be carried out according to the actual capacity requirements. When the capacity of a single box frame 1 can meet the requirements, the top cover 305 can be directly aligned with the pad 303 and snapped onto the top of the pad 303. After the grid plate 301 and the sealing plate 302 are sequentially snapped onto the side wall of the box frame 1, the assembly of the single box frame 1 distribution box is completed. When the capacity of a single box frame 1 cannot meet the demand, after the installation of the pad 303 is completed, the grid plate 301 is installed on the two side walls of the box frame 1 in sequence. Here, it is optional to install the sealing plate 302 on the outer side of the grid plate 301 to isolate the connection between the two box frames 1, or it is optional not to install the sealing plate 302 to allow the box frames 1 to communicate with each other. Then repeat the above steps to install the two box frames 1 side by side, and make the protective frame 304 simultaneously cover the two side by side pads 303 and install it on the two side by side pads 303. When the capacity of two box frames 1 is sufficient to meet the requirements, the two top covers 305 can be directly aligned with the pads 303, and they can be sequentially clipped onto the tops of the two parallel pads 303. Then, each connecting rod 318 can be rotated sequentially so that its end is connected to the corresponding threaded sleeve 325 on the guard 304, thus completing the assembly of the double box frame 1 distribution box. If the capacity still cannot meet the demand, you can choose to continue to add box frames 1. After the installation of the protective frame 304 is completed, insert two pads 303 into the top of the protective frame 304. At this time, the protective frame 304 will simultaneously frame four pads 303. Then, align the two box frames 1 with the pads 303 at the top of the protective frame 304 and engage the two box frames 1 with the pads 303 at the top of the protective frame 304 in sequence. The aforementioned steps can then be repeated to assemble the grid plate 301, sealing plate 302, pad 303, guard frame 304, and rear seat 307 in sequence, thus completing the assembly of the double-layer or even multi-layer box frame 1. During this process, the threaded sleeves 325 on the adjacent guard frames 304 are connected in sequence through the corresponding number of connecting rods 318. Finally, the two top covers 305 are aligned with the top pad 303 and are sequentially snapped onto the top of the two parallel pads 303 on the top layer, thus completing the assembly of the multi-layer box frame 1 distribution box body. In the aforementioned process, when assembling the single-frame 1 distribution box and the double-frame 1 distribution box, that is, when it is not necessary to assemble the second layer or even more layers of the box frame 1, the conduit 323 can be directly connected to the connecting valve 322. When it is necessary to assemble the second layer or even more layers of the box frame 1, it is necessary to use external connectors and pipes to connect each connecting valve 322 to the conduit 323 in sequence. After completing the connection work between the connecting valve 322 and the conduit 323, hydraulic fluid is injected into the on / off valve 35. Hydraulic fluid will flow through the on / off valve 35 into the bottom cavity 31. With the connection of the connecting hole 33, the hydraulic fluid will flow into the horizontal cavity 32, which will squeeze the push plate 312, overcome the resistance of the return spring 313, and push the insertion rod 311 to insert it into the insertion port 34. With the connection of the bend pipe 319, the hydraulic fluid will flow into the vertical box 314, which will press the sliding plug 316, causing the sliding plug 316 to drag the support rod 315. Furthermore, under the linkage of the threaded cylinder 317, connecting rod 318 and threaded sleeve 325, the guard 304 will be synchronously dragged, which will press the pad 303, making it more stably engaged with the box frame 1. Then, the hydraulic fluid will be injected into the conduit 323 and injected into the chamber where the piston 321 is located through the connecting valve 322. Under its pressure, the piston 321 pushes the pin 320, so that the pin 320 is inserted into the ear plate 324. Then, under the hydraulic action of the hydraulic fluid, through the aforementioned process, the components are locked together. At the same time, the hydraulic fluid will also press against the bottom pad 309, and the bottom pad 309 will slide relative to the base 306, making the base 306 rise. During the subsequent use of the distribution box, as electronic components are installed, the weight of the electronic components and the distribution box itself will be applied to the hydraulic fluid. Furthermore, under the transmission action of the hydraulic fluid, it will be converted into the limiting and locking force of each component, making the components more stably locked. At the same time, when the distribution box is disturbed by external forces such as ground vibration, the disturbance force will also act on the hydraulic fluid, and under the transmission action of the hydraulic fluid, it will be gradually dispersed with the flow of the hydraulic fluid, converting it into locking force, expanding the action area, and improving the balance and stability of the distribution box. After completing the aforementioned work, the threaded ring 203 can be aligned with the screw 201, the screw 201 can be held and the threaded ring 203 can be rotated to install the spacer 205 on the screw 201. According to the number of spacers 205 required for a single box frame 1, the corresponding number of spacers 205 can be installed on the screw 201 in sequence. Then, the clamp 224 can be installed on the end of the screw 201, the spacer 205 can be sent into the box frame 1, and the clamp cap 223 can be pressed. After the clamp 224 is aligned with the clamp cap 223, the clamp cap 223 can be released. Under the pressure of the compression spring 225, the clamp cap 223 will lock the clamp 224, thus completing the installation of the spacer 205. Then, rotate bolt 221 to disengage it from corner block 202, releasing the restriction on partition 205. Under the elastic pull of tension spring 207, extension plate 206 will slide along slide rod 204 and push partition 205 out of box frame 1. Then, external cable guide connection and related electronic component installation can be carried out. The external cable is sequentially threaded into the junction box 308, and pulled so that it passes through the guide ring 219 on the corresponding suspension seat 211, passes over the top of the suspension roller 215, passes through the gap between the two corner rollers 209 on the side near the junction box 308 into the air cushion 218 on the perforated plate 208, and passes out through the gap between the two corner rollers 209 on the other side of the perforated plate 208, thus completing the traction and guidance of the external cable. Then, the corresponding electronic components can be installed on the spacer 205. Here, the threaded ring 203 can be rotated to drive the spacer 205 to rise and fall. The gap between the spacers 205 can be steplessly adjusted according to the size of the actual installed electronic components, and the internal space of the box frame 1 can be divided accordingly to fit the size of the electronic components and maximize the use of the internal space of the box frame 1. Next, the external cable can be connected to the electronic components, and then air is injected into the air cushion 218 to lock the cable on the inside of the air cushion 218, completing the guiding connection of the external cable and the installation of related electronic components. Then, the partition 205 is pushed into the box frame 1, reset, and the bolt 221 is rotated to connect with the corner block 202 to limit the partition 205. The box door 11 is then closed to start the power supply and distribution work. During the subsequent use of the distribution box, open the box door 11, turn the bolt 221 to release the limit on the partition 205, and the partition 205 will automatically pop out of the box frame 1 under the pull of the tension spring 207, which can improve the convenience and safety of later control and maintenance work. During the process of the partition 205 popping out of the box frame 1, under the limiting and holding of the air cushion 218, the cable will remain stationary relative to the extension plate 206 to avoid the cable end being pulled, thus ensuring the connection stability between the cable and the electronic components. Correspondingly, as the partition 205 is pulled out, the cable will be pulled. At this time, the cable will press the suspension roller 215, so that it overcomes the tension of the spring 217 and drives the slider 214 to approach the suspension seat 211. The suspension seat 211 will also overcome the elasticity of the compression spring 212 under the pressure of the cable and slide down to approach the perforated plate 208, shortening the cable length contained between the perforated plate 208 and the suspension seat 211, thus compensating for the displacement during the popping process of the partition 205. During the cable traction and installation process, the threaded ring 216 can be rotated to move along the crossbar 213. Under the drag of the spring 217, the slider 214 will move synchronously along the crossbar 213, adjusting the distance between the suspension roller 215 and the suspension seat 211. This allows for adjustment of the cable length contained between the perforated plate 208 and the suspension seat 211 to accommodate the displacement deviation during the ejection process of the spacer 205, and simultaneously control the tension of the spring 217 during the ejection process of the spacer 205, limiting the tensile force on the cable during this process. When the spacer 205 is reset, as the spacer 205 is pushed into the box frame 1, the slider 214 will also slide along the crossbar 213 to reset under the pull of the spring 217, so that the suspension roller 215 moves away from the suspension seat 211. Under the elastic pressure of the compression spring 212, the suspension seat 211 will reset and rise, moving away from the perforated plate 208, increasing the length of the cable contained between the perforated plate 208 and the suspension seat 211, collecting the cable released during the process of pushing the spacer 205 in, keeping the cable taut, avoiding the cable from being scattered and tangled, and ensuring its working stability. During this process, the rotation of the suspension roller 215 and the rolling of the ball bearing 220 can effectively reduce the friction of the cable during displacement, reduce cable wear, and make the aforementioned process smoother. Similarly, in subsequent use, when the cable is pulled to the outside of the distribution box by external force, under the limiting and holding of the air cushion 218, the cable end will remain stationary relative to the extension plate 206. The cable will press the suspension roller 215 and the suspension seat 211, causing them to displace and preferentially release the cable contained between the perforated plate 208 and the suspension seat 211, avoiding the cable end being pulled and ensuring the connection stability between the cable and electronic components.
