[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a modular installation structure of a power distribution cabinet, including three connection cabinets 1, the bottoms of the three connection cabinets 1 are all fixedly connected with a first connection plate 2, the outer wall of one of the three first connection plates 2 is movably sleeved with a support cabinet 3, the tops of the three connection cabinets 1 are all provided with a first connection groove 4, the inner wall of one of the three first connection grooves 4 is movably inserted with a second connection plate 5, the top of the second connection plate 5 is fixedly connected with a rain cover 6, the outer walls of the three connection cabinets 1 and the support cabinet 3 are all fixedly installed with a group of fixing blocks 7, one side of the outer wall of the four groups of fixing blocks 7 is provided with an installation groove 8, the inner wall of the four groups of installation grooves 8 is fixedly connected with a reset spring 9, and the four groups of reset springs 9 are fixedly connected to the inner wall of the four groups of reset springs 9. The outer wall of the positioning spring 9 is fixedly connected with a trapezoidal block 10, the outer wall of the three connecting cabinets 1 and the rainproof cover 6 is fixedly installed with a group of card plates 11, one side of the outer wall of the four groups of card plates 11 is provided with a limiting groove 12, the bottom of the four groups of card plates 11 is provided with a card slot 13, and the four groups of fixed blocks 7 are movably inserted inside the four groups of card slots 13, one side of the outer wall of the three connecting cabinets 1 is fixedly installed with a group of hinges 14, the rotating ends of the three groups of hinges 14 are fixedly connected with cabinet doors 15, the tops of the three cabinet doors 15 are provided with second connecting grooves 16, the bottoms of the three cabinet doors 15 are fixedly connected with a first receiving plate 17, and a handle 18 is fixedly installed on one side of the outer wall of one of the three cabinet doors 15.

[0024] The effect achieved by the entire embodiment 1 is that the distribution cabinet adopts a modular installation design, and its structure is mainly divided into a connecting cabinet 1, a supporting cabinet 3 and a rainproof cover 6. The first connecting plate 2 cooperates with the embedding groove opened on the top of the supporting cabinet 3, so that the connecting cabinet 1 can easily achieve initial and stable docking with the supporting cabinet 3. At the same time, the three first connecting plates 2 and the three first connecting grooves 4 cooperate closely, ensuring that the three connecting cabinets 1 can be initially and tightly connected. In addition, the cooperation between the second connecting plate 5 and the first connecting groove 4 enables the connecting cabinet 1 and the rainproof cover 6 to be initially and firmly connected, effectively enhancing the rainproof performance of the distribution cabinet. Fixed blocks 7 and card boards 11 are also used between the connecting cabinet 1, the supporting cabinet 3 and the rainproof cover 6 to strengthen the fixation to ensure the close combination of the components. When the fixed block 7 is inserted into the card slot 13 at the bottom of the card plate 11, the card slot 13 The inner surface wall will squeeze the inclined surface of the trapezoidal block 10, causing it to shrink into the installation groove 8 and squeeze the reset spring 9. When the fixing block 7 is completely inserted into the interior of the slot 13, one side of the outer wall of the trapezoidal block 10 corresponds exactly to the position of the limiting groove 12. Under the elastic force of the reset spring 9, the trapezoidal block 10 will pop out and be inserted into the limiting groove 12, thereby realizing a fastening connection between the cabinet bodies, and through the cooperation of the second connecting groove 16 and the first receiving plate 17, the three cabinet doors 15 can be tightly connected, further enhancing the sealing of the distribution cabinet. In this way, the assembly process of the distribution cabinet is greatly simplified, which greatly facilitates the transportation of the distribution cabinet, while ensuring the stability and reliability of the overall structure, and the height of the distribution cabinet can be adjusted by increasing or decreasing the number of connected cabinet bodies 1 according to actual use requirements, thereby meeting the height requirements in different application scenarios.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, a group of fixing frames 19 are fixedly installed on the inner walls of the three connected cabinets 1, a third connecting groove 20 is opened on the top of the three groups of fixing frames 19, and a second receiving plate 21 is fixedly connected to the bottom of the three groups of fixing frames 19. Multiple groups of fixing grooves 22 are opened on one side of the outer walls of the three groups of fixing frames 19, and six groups of fixing bolts 23 are movably inserted into the inner walls of the multiple groups of fixing grooves 22. Among the six groups of fixing bolts 23, mounting plates 24 are movably sleeved between the outer walls of three groups, and nuts 25 are threadedly connected to the outer walls of the six groups of fixing bolts 23. Among the six groups of fixing bolts 23, the outer walls are movably sleeved with partitions 26.

[0026] The effect achieved by the entire embodiment 2 is that after the connecting cabinet 1 is assembled, the two adjacent second receiving plates 21 will be accurately inserted into the corresponding two third connecting grooves 20, so that the connection between the two adjacent connecting cabinets 1 is more stable and the structural stability of the entire distribution cabinet is effectively improved. At the same time, in order to meet the installation requirements of electrical components of different sizes, the staff can easily loosen the nut 25 and adjust the position of the fixing bolt 23, thereby conveniently adjusting the position of the mounting plate 24 and the partition 26, so that the distribution cabinet can meet the actual installation requirements of electrical components of different sizes, thereby improving the applicability and flexibility of the distribution cabinet. In addition, according to actual needs, the staff can also adapt to different numbers of electrical components by increasing or decreasing the number of mounting plates 24 and partitions 26. This method not only optimizes the internal space utilization of the distribution cabinet, but also improves the installation efficiency and layout rationality of electrical components.

[0027] Working principle: When using the power distribution cabinet, the overall structure is divided into three parts: multiple connecting cabinets 1, supporting cabinets 3 and rainproof covers 6 through modular design, which greatly facilitates the transportation process of the power distribution cabinet. During installation, first, the first connecting plate 2 is accurately inserted into the embedding groove on the top of the supporting cabinet 3 to achieve the initial and stable docking between the connecting cabinet 1 and the supporting cabinet 3. Subsequently, the multiple first connecting plates 2 are respectively inserted into the interior of the multiple first connecting grooves 4 to achieve the initial connection between the multiple connecting cabinets 1 to form an overall structure. At the same time, the multiple first receiving plates 17 are respectively accurately inserted into the corresponding second connecting grooves 16 to ensure the tight connection between the multiple cabinet doors 15, thereby enhancing the sealing and safety of the power distribution cabinet. Next, the second connecting plate 5 is inserted into the adjacent first connecting grooves 4 to achieve the initial connection between the connecting cabinet 1 and the rainproof cover 6, thereby enhancing the rainproof performance of the power distribution cabinet. During the docking process, the multiple fixing blocks 7 are respectively accurately inserted into the corresponding card slots 13. When the fixing blocks 7 are fully inserted into the card slots 13, the inner walls of the card slots 13 will squeeze the ladder. The inclined surface of the trapezoidal block 10 causes it to shrink into the installation groove 8 and squeeze the reset spring 9. As the fixing block 7 is fully inserted, the trapezoidal block 10 pops up under the elastic force of the reset spring 9 and is accurately inserted into the limit groove 12, thereby firmly connecting the adjacent cabinets, realizing a fastening connection between multiple connected cabinets 1, the supporting cabinet 3 and the rain cover 6, and improving the overall stability of the distribution cabinet. After the assembly of multiple connected cabinets 1 is completed, the adjacent second receiving plate 21 will be accurately inserted into the interior of the third connecting groove 20, thereby enhancing the stability between the two adjacent connected cabinets 1. At this time, the staff can flexibly adjust the position of the mounting plate 24 and the partition 26 by adjusting the fixing bolts 23 and the nuts 25, so as to adapt to the installation requirements of electrical components of different sizes. At the same time, the number of mounting plates 24 and partitions 26 can be increased or decreased as needed, which can optimize space utilization, thereby improving installation efficiency and layout rationality. This modular design simplifies the assembly process and improves the stability and practicality of the distribution cabinet. At the same time, its excellent flexibility and customizability meet the needs of different application scenarios.
