Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, specifically to a power distribution cabinet with a scalable architecture. Background Technology

[0002] Distribution cabinets are the most common electrical equipment, mainly including power distribution cabinets, lighting distribution cabinets, metering cabinets, etc. Circuit components such as switches and meters are generally installed inside the cabinet. Due to the relatively small space inside the cabinet, the installation of equipment and wiring are relatively complicated, especially in the later maintenance process, which brings a lot of inconvenience to the operators.

[0003] In the prior art, Chinese patent publication number "CN208045989U" discloses an expandable power distribution cabinet. When expansion is not needed, the baffle and folding plate can be hidden inside the cabinet. When expansion is needed, the movable panel and files can be pushed out, and then the folding plate and baffle can be firmly connected with bolts using positioning strips. The operation is simple and convenient, and the expansion effect is good, which solves the problem that existing power distribution cabinets cannot expand space.

[0004] As described above, the combination of baffles and folding plates enables the expansion of the distribution cabinet's space. However, in this scheme, the baffles and folding plates can only achieve spatial expansion in one direction, which limits the space. Furthermore, the folding plates and baffles need to be connected by spirals, which increases the difficulty of assembly and disassembly and reduces work efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a scalable power distribution cabinet, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A scalable power distribution cabinet includes a base plate and a top plate. A front side plate, a rear side plate, a left side plate, and a right side plate are provided between the base plate and the top plate. A connecting component is provided on both the base plate and the top plate. An upper expansion plate and a lower expansion plate are provided on the connecting component. Four upper slots are provided on the upper expansion plate, and a lower slot is provided on the lower expansion plate.

[0008] Upper locking blocks are fixedly installed on the upper surfaces of the front side plate, rear side plate, left side plate, and right side plate, and lower locking blocks are fixedly installed on the lower surfaces of the front side plate, rear side plate, left side plate, and right side plate.

[0009] Extension components are provided on the front side panel, rear side panel, left side panel and right side panel;

[0011] Preferably, the connecting assembly includes bearings fixedly mounted on the upper and lower expansion plates, a connecting shaft fixedly mounted on the bearings, symmetrically arranged hinges fixedly mounted on the side end faces of the upper and lower expansion plates, and the four corners of the upper and lower expansion plates being set as planes.

[0012] Preferably, the upper expansion plate is divided into four upper flip plates, and the lower expansion plate is divided into four lower flip plates. The four upper flip plates and the four lower flip plates are shaped as equilateral triangles. The upper surface of each upper flip plate has symmetrically arranged upper half slots, and the lower surface of each lower flip plate has symmetrically arranged lower half slots.

[0013] Preferably, the four upper slots are respectively disposed on the four upper flip plates, and the four lower slots are respectively disposed on the four lower flip plates. The upper expansion plate is fixedly installed on the base plate by a connecting shaft, and the lower expansion plate is fixedly installed on the top plate by a connecting shaft. The upper card block is embedded in the lower half slot, and the lower card block is embedded in the upper half slot.

[0014] Preferably, the extension component includes a first storage slot formed on the front and rear side panels and a second storage slot on the left and right side panels, wherein a first extension plate is slidably installed inside the first storage slot and a second extension plate is slidably installed inside the second storage slot.

[0015] Preferably, the first extension plate and the second extension plate have different lengths, the first extension plate is located inside the second extension plate, and the end faces of the first extension plate and the second extension plate are in contact.

[0016] Preferably, the stabilizing component includes four adjustment slots on the base plate, and a front stabilizing plate, a rear stabilizing plate, a left stabilizing plate and a right stabilizing plate are slidably installed inside the four adjustment slots respectively. Each of the front stabilizing plate, the rear stabilizing plate, the left stabilizing plate and the right stabilizing plate has a threaded fixed hole.

[0017] Preferably, each of the four adjustment slots has a first threaded hole and a second threaded hole at its inner bottom. A fastening bolt is threaded onto the first threaded hole. A first support plate is fixedly installed on both the front and rear stabilizing plates, and a second support plate is fixedly installed on both the left and right stabilizing plates.

[0018] This invention provides a scalable power distribution cabinet. Compared with the prior art, it has the following advantages:

[0019] 1. This invention divides the original integrated power distribution cabinet into a base plate, top plate, front side plate, rear side plate, left side plate, and right side plate. By using four upper slots on the upper expansion plate to be fitted with the lower slots of the front side plate, rear side plate, left side plate, and right side plate, and four lower slots on the lower expansion plate to be fitted with the upper slots of the front side plate, rear side plate, left side plate, and right side plate, the power distribution cabinet can be assembled and disassembled quickly without complicated tools or time, thus improving work efficiency.

[0020] 2. In this invention, four upper flip-up plates on the upper expansion plate are unfolded, and four lower flip-up plates on the lower expansion plate are unfolded. Then, the first extension plates on the front and rear side plates are pulled out from the first storage slot, and the second extension plates on the left and right side plates are pulled out from the second storage slot. The upper slots on the upper flip-up plates are respectively embedded with the lower slots on the front, rear, left, and right side plates, and the lower slots on the lower flip-up plates are respectively embedded with the upper slots on the front, rear, left, and right side plates, thereby realizing the installation of the power distribution cabinet and increasing the usable space of the power distribution cabinet.

[0021] 3. In this invention, when it is necessary to expand the space of the power distribution cabinet, the assembled power distribution cabinet is disassembled, and then the upper expansion plate and the lower expansion plate are kept in place with the connecting shaft as the center, so that the bottom plate and the top plate are rotated forty-five degrees. The bottom plate and the top plate after rotation are used to enhance the stability of the upper flip plate and the lower flip plate.

[0022] 4. In this invention, when the space of the distribution cabinet is increased, the front, rear, left, and right stabilizing plates are adjusted in position within the four adjustment slots by rotating the fastening bolts. This adjusts the threaded holes on the front, rear, left, and right stabilizing plates from the original position of the first threaded hole to the position of the second threaded hole. Then, the fastening bolts are rotated again to fix the front, rear, left, and right stabilizing plates. The stability of the distribution cabinet is ensured by the cooperation of the first and second support plates on the front, rear, left, and right stabilizing plates. Attached Figure Description

The bottom plate 1 and the top plate 2 are in the same vertical direction, and the front side panel 3, rear side panel 4, left side panel 5 and right side panel 6 are located between the bottom plate 1 and the top plate 2. At the same time, a cabinet door can be installed on one of the side panels of the front side panel 3, rear side panel 4, left side panel 5 and right side panel 6 according to the needs of the personnel. Since the structure of the cabinet door is a technology well known to those skilled in the art, it will not be described in detail here.

[0035] In this embodiment, the original integrated power distribution cabinet is divided into a base plate 1, a top plate 2, a front side plate 3, a rear side plate 4, a left side plate 5, and a right side plate 6. The four upper slots 9 on the upper extension plate 7 are respectively fitted with the lower slots 12 of the front side plate 3, the rear side plate 4, the left side plate 5, and the right side plate 6, and the four lower slots 10 on the lower extension plate 8 are respectively fitted with the upper slots 11 of the front side plate 3, the rear side plate 4, the left side plate 5, and the right side plate 6. This allows for the rapid assembly of the power distribution cabinet without the need for complicated tools or time, enabling quick assembly or disassembly of the power distribution cabinet and improving work efficiency.

[0036] The connecting assembly includes bearings 13 fixedly mounted on the upper extension plate 7 and the lower extension plate 8, a connecting shaft 14 fixedly mounted on the bearings 13, hinges 15 symmetrically arranged fixedly mounted on the side end faces of the upper extension plate 7 and the lower extension plate 8, the four corners of the upper extension plate 7 and the lower extension plate 8 are all set as planes 16, the upper extension plate 7 is divided into four upper flip plates 17, the lower extension plate 8 is divided into four lower flip plates 18, the four upper flip plates 17 and the four lower flip plates 18 are shaped as equilateral triangles, the upper end face of the upper flip plate 17 is provided with symmetrically arranged upper half slots 19, and the lower end face of the lower flip plate 18 is provided with symmetrically arranged lower half slots 20.

[0037] Four upper slots 9 are respectively set on four upper flip plates 17, and four lower slots 10 are respectively set on four lower flip plates 18. The upper extension plate 7 is fixedly installed on the base plate 1 through the connecting shaft 14, and the lower extension plate 8 is fixedly installed on the top plate 2 through the connecting shaft 14. The upper locking block 11 is embedded in the lower half slot 20, and the lower locking block 12 is embedded in the upper half slot 19. The extension assembly includes a first storage slot 21 opened on the front side plate 3 and the rear side plate 4, and a second storage slot 22 opened on the left side plate 5 and the right side plate 6. A first extension plate 23 is slidably installed inside the first storage slot 21, and a second extension plate 24 is slidably installed inside the second storage slot 22. The lengths of the first extension plate 23 and the second extension plate 24 are different. The position of the first extension plate 23 is inside the second extension plate 24. The end faces of the first extension plate 23 and the second extension plate 24 are in contact. The cooperation of the first extension plate 23 and the second extension plate 24 forms a new side plate. The volume of this side plate is much larger than that of the original side plate.

[0038] In this embodiment, when it is necessary to expand the space of the power distribution cabinet, the assembled power distribution cabinet is disassembled. Then, with the connecting shaft 14 as the center, the positions of the upper expansion plate 7 and the lower expansion plate 8 are kept unchanged, thereby rotating the bottom plate 1 and the top plate 2 by 45 degrees. Then, the four upper flip plates 17 on the upper expansion plate 7 are unfolded, and the four lower flip plates 18 on the lower expansion plate 8 are unfolded. Then, the first extension plates 23 on the front side plate 3 and the rear side plate 4 are pulled out from the first storage slot 21, and the second extension plates 24 on the left side plate 5 and the right side plate 6 are pulled out from the second storage slot 22. Then, the upper slots 9 on the upper flip plates 17 are respectively fitted with the lower slots 12 on the front side plate 3, the rear side plate 4, the left side plate 5 and the right side plate 6, and the lower slots 10 on the lower flip plates 18 are respectively fitted with the upper slots 11 on the front side plate 3, the rear side plate 4, the left side plate 5 and the right side plate 6, thereby realizing the installation of the power distribution cabinet and increasing the usable space of the power distribution cabinet.

[0039] A stabilizing assembly is provided on the base plate 1. The stabilizing assembly includes four adjusting slots 25 on the base plate 1. A front stabilizing plate 26, a rear stabilizing plate 27, a left stabilizing plate 38, and a right stabilizing plate 29 are slidably installed inside the four adjusting slots 25, respectively. Each of the four adjusting slots 25 has a threaded hole 30. A first threaded hole 31 and a second threaded hole 32 are provided at the bottom of each of the four adjusting slots 25. A fastening bolt 33 is threaded onto the first threaded hole 31. A first support plate 34 is fixedly installed on the front stabilizing plate 26 and the rear stabilizing plate 27. A second support plate 35 is fixedly installed on the left stabilizing plate 38 and the right stabilizing plate 29. The ground of the first support plate 34 and the second support plate 35 is at the same level 16 as the ground of the base plate 1, ensuring that the first support plate 34 and the second support plate 35 are stable.

[0040] In this embodiment, after the space of the distribution cabinet is increased, the front stabilizing plate 26, rear stabilizing plate 27, left stabilizing plate 38 and right stabilizing plate 29 are adjusted in the four adjustment slots 25 by rotating the fastening bolt 33. This adjusts the threaded holes 30 on the front stabilizing plate 26, rear stabilizing plate 27, left stabilizing plate 38 and right stabilizing plate 29 from the original position of the first threaded hole 31 to the position of the second threaded hole 32. Then, the fastening bolt 33 is rotated again to fix the front stabilizing plate 26, rear stabilizing plate 27, left stabilizing plate 38 and right stabilizing plate 29. The stability of the distribution cabinet is ensured by the cooperation of the first support plate 34 and the second support plate 35 on the front stabilizing plate 26, rear stabilizing plate 27, left stabilizing plate 38 and right stabilizing plate 29.

[0041] Working principle:

[0042] The installation principle of the power distribution cabinet is as follows: The original integrated power distribution cabinet is divided into a base plate 1, a top plate 2, a front side plate 3, a rear side plate 4, a left side plate 5, and a right side plate 6. The four upper slots 9 on the upper extension plate 7 are respectively inserted into the lower slots 12 of the front side plate 3, the rear side plate 4, the left side plate 5, and the right side plate 6, and the four lower slots 10 on the lower extension plate 8 are respectively inserted into the upper slots 11 of the front side plate 3, the rear side plate 4, the left side plate 5, and the right side plate 6. This allows for the rapid assembly of the power distribution cabinet without the need for complicated tools or time. The assembly or disassembly of the power distribution cabinet can be completed quickly, improving work efficiency.

[0043] The principle of the power distribution cabinet with expanded space: unfold the four upper flip-up plates 17 on the upper expansion plate 7, and unfold the four lower flip-up plates 18 on the lower expansion plate 8. Then, pull out the first extension plates 23 on the front side plate 3 and the rear side plate 4 from the first storage slot 21, and pull out the second extension plates 24 on the left side plate 5 and the right side plate 6 from the second storage slot 22. Then, use the upper slots 9 on the upper flip-up plates 17 to fit into the lower slots 12 of the front side plate 3, the rear side plate 4, the left side plate 5 and the right side plate 6 respectively, and use the lower slots 10 on the lower flip-up plates 18 to fit into the upper slots 11 of the front side plate 3, the rear side plate 4, the left side plate 5 and the right side plate 6 respectively, so as to realize the installation of the power distribution cabinet and increase the usable space of the power distribution cabinet.

[0044] When it is necessary to expand the space of the power distribution cabinet, the assembled power distribution cabinet is disassembled. Then, with the connecting shaft 14 as the center, the positions of the upper expansion plate 7 and the lower expansion plate 8 are kept still, thereby rotating the bottom plate 1 and the top plate 2 by 45 degrees. The rotation of the bottom plate 1 and the top plate 2 is used to enhance the stability of the upper flip plate 17 and the lower flip plate 18.

[0045] After the space of the distribution cabinet is increased, the front stabilizing plate 26, rear stabilizing plate 27, left stabilizing plate 38 and right stabilizing plate 29 are adjusted in the four adjustment slots 25 by rotating the fastening bolt 33. The threaded holes 30 on the front stabilizing plate 26, rear stabilizing plate 27, left stabilizing plate 38 and right stabilizing plate 29 are adjusted from the original position of the first threaded hole 31 to the position of the second threaded hole 32. Then, the fastening bolt 33 is rotated again to complete the fixation of the front stabilizing plate 26, rear stabilizing plate 27, left stabilizing plate 38 and right stabilizing plate 29. The stability of the distribution cabinet is ensured by the cooperation of the first support plate 34 and the second support plate 35 on the front stabilizing plate 26, rear stabilizing plate 27, left stabilizing plate 38 and right stabilizing plate 29.
