Description

Technical Field

[0001] This invention relates to the field of power distribution cabinets, and in particular to a modular low-voltage power distribution cabinet. Background Technology

[0002] Modular low-voltage switchgear is an electrical device used for power distribution, control, and protection. It typically integrates electrical components such as circuit breakers, contactors, relays, and meters into standardized modules, which are then assembled using a unified interface and structure. This type of switchgear features a compact structure, flexible configuration, and ease of expansion and maintenance, and is widely used in industrial, commercial, and residential power distribution systems. Its modular design not only facilitates mass production and rapid assembly but also improves system maintainability and reliability. However, in practical applications, traditional modular low-voltage distribution cabinets still have significant shortcomings. While commonly used distribution cabinets employ a modular layout, the spacing between electrical component modules is usually fixed and small, lacking an effective spacing adjustment mechanism. This problem mainly stems from the simple structure of the mounting racks within the cabinet and the rigid module positioning method, resulting in limited operating space and a cumbersome installation process when installing or replacing modules of different sizes. Furthermore, during maintenance, the narrow module gaps make it difficult for personnel to directly observe internal wiring, component status, and potential hazards, and testing instruments and tools cannot be easily inserted, severely impacting maintenance efficiency and accuracy. In the long run, this deficiency not only increases maintenance costs and safety risks but also reduces the overall practicality of the distribution cabinet and the user experience, hindering its further application in efficient and intelligent power distribution scenarios.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the present invention provides a technical solution: a modular low-voltage distribution cabinet, including a distribution cabinet body 1, an adjustment component 2 disposed inside the distribution cabinet body 1; a moving component 3 disposed inside the distribution cabinet body 1; and an installation component 4 disposed inside the distribution cabinet body 1. The adjustment component 2 includes four limiting frames 201 fixedly connected to the inner side wall of the distribution cabinet body 1, the four limiting frames 201 being located on the inner side walls of both sides of the distribution cabinet body 1, and the four limiting frames 201 being divided into two groups, symmetrically distributed about the horizontal symmetrical surface of the distribution cabinet body 1. The four limiting frames 201 are slidably connected to a movable frame 202 on their inner sidewalls. A fixed rod 205 is fixedly connected to the inner sidewall of the movable frame 202. Several fixed rods 205 are arranged in a linear array along the inner sidewall of the movable frame 202. Taking one fixed rod 205 as an example, two movable blocks 206 are slidably connected to its outer sidewall. The two movable blocks 206 are located at opposite ends of the fixed rod 205. An adjusting rod 209 is slidably connected to the outer sidewall of the fixed rod 205. Multiple adjusting rods 209 are provided, arranged in a linear array on the outer wall of the fixed rod 205. A guide rod 203 is rotatably connected to the inner top of the main body 1. Two guide rods 203 are provided, each with a guide groove 204 at its bottom. Columns 207 are rotatably connected to the inner walls of two moving blocks 206, with one end of each column 207 located inside the guide grooves 204. A connecting rod 211 is rotatably connected to the end of each adjusting rod 209 away from the fixed rod 205. Multiple connecting rods 211 are provided with… Multiple connecting rods 211 are divided into multiple groups, and each group of connecting rods 211 is interconnected. Several connecting rods 211 are interconnected to form a scissor fork assembly. Taking one group as an example, this group consists of two connecting rods 211 arranged in a cross shape, and both connecting rods 211 are rotatably connected to the outer wall of the adjusting rod 209. The outer walls of the two moving blocks 206 are provided with limiting grooves 208. One end of each connecting rod 211 in this group is located inside the limiting groove 208. The outer wall of the fixed rod 205 is fitted with a support spring 210, which is located between the adjusting rod 209 and the moving block 206. In use, the two guide rods 203 are rotated about their respective connection points with the inner wall of the main body 1 of the distribution cabinet, so that the two guide rods 203 are distributed in a trumpet shape. When the moving frame 202 is moved, the moving frame 202 drives the column 207 to move synchronously. When the moving frame 202 moves away from the interior of the main body 1 of the distribution cabinet, the two guide rods 203 are distributed in a trumpet shape. At this time, the movement of the moving frame 202 drives the column 207 to move synchronously. One end of the two columns 207 is located inside the two guide grooves 204, so when the columns 207 move, they are guided by the two guide rods 203 and gradually move away from each other. At this time, the two columns 207 drive the two moving blocks 206 to move synchronously, so that the two moving blocks 206 gradually move away from the outer wall of the fixed rod 205. The two ends of the scissor fork structure formed by the interconnected connecting rods 211 are located inside the two limiting grooves 208. When the two moving blocks 206 move away from each other, the scissor fork structure formed by the connecting rods 211 is gradually stretched. Since a set of connecting rods 211 is rotatably connected to the outer wall of the adjusting rod 209, the outer wall of the scissor fork structure is provided with multiple adjusting rods 209. Multiple support springs 210 are located between multiple sets of spaced adjusting rods 209. As the two moving blocks 206 move away from each other, the scissor fork group formed by multiple connecting rods 211 will be stretched. This will further increase the distance between the multiple adjusting rods 209, thereby increasing the distance between the electrical components set on the adjusting rods 209. This makes it easier for the operator to observe the gaps between the electrical components and avoid potential hazards between the electrical components.

[0028] like Figure 1 , Figure 2 , Figure 3As shown, a fixing block 220 is fixedly connected to the top of the main body 1 of the distribution cabinet. A first threaded rod 219 is rotatably connected to the top of the fixing block 220. A motor 217 is fixedly connected to the top of the main body 1 of the distribution cabinet. The motor 217 is connected to an external power supply. The output end of the motor 217 is fixedly connected to one end of the first threaded rod 219. A rotating rod 221 is rotatably connected to the top of the fixing block 220. There are two rotating rods 221, which are located at opposite ends of the fixing block 220. Taking one of the rotating rods 221 as an example, a connecting post 218 is fixedly connected to the bottom of the end of the rotating rod 221 away from the fixing block 220. The end of the connecting post 218 away from the rotating rod 221 is fixedly connected to the top of the guide rod 203. A threaded sleeve 222 is threadedly connected to the outer wall of the first threaded rod 219. A push rod 223 is fixedly connected to the outer wall of the threaded sleeve 222. There are two moving rods 223. The two pushing rods 223 are located at both ends of the threaded sleeve 222. The two pushing rods 223 are slidably connected to the top of the two rotating rods 221. In use, the operator starts the motor 217. Driven by the motor 217, the first threaded rod 219 rotates, thereby driving the threaded sleeve 222 to move along the first threaded rod 219. When the threaded sleeve 222 moves, it will drive the two pushing rods 223 to move synchronously. Since the two pushing rods 223 are slidably connected to the two rotating rods 221, when the two pushing rods 223 move synchronously with the threaded sleeve 222, it will drive the angle between the two rotating rods 221 to change. Thus, through the two connecting posts 218, the two rotating rods 221 drive the two guide rods 203 to rotate, thereby adjusting the angle between the two guide rods 203.

[0029] like Figure 3 , Figure 5As shown, the inner wall of the movable frame 202 has a cavity 212. There are two cavities 212, located in the upper and lower parts of the movable frame 202 respectively. Taking one cavity 212 as an example, a limit rod 214 is fixedly connected to the inner wall of the movable frame 202. The limit rod 214 is located inside the cavity 212. A return spring 215 is fixedly connected to the inner wall of the movable frame 202. A cylinder 213 is fixedly connected to the end of the return spring 215 away from the inner wall of the movable frame 202. The cylinder 213 is located inside the cavity 212, and its outer wall is in contact with the inner wall of the movable frame 202. The inner wall is slidably connected to the outer wall of the limiting rod 214. The end of the cylinder 213 away from the return spring 215 is located inside the limiting frame 201. In use, the two return springs 215 use their own elasticity to abut one end of the two cylinders 213, so that the ends of the two cylinders 213 close to the two limiting frames 201 are respectively located inside the two limiting frames 201. Then, the two limiting frames 201 support the moving frame 202. The operator can retract the two cylinders 213, so that the two cylinders 213 are returned to the inside of the moving frame 202, thereby releasing the support of the limiting frame 201 on the moving frame 202.

[0030] like Figure 5 As shown, a gripping block 216 is fixedly connected to the outer wall of the cylinder 213. The number and position of the gripping blocks 216 correspond to the number and position of the cylinder 213, so that the operator can adjust the cylinder 213. A tray is provided on the bottom outer wall of the moving frame 202 for placing tools.

[0031] like Figure 1 , Figure 6 As shown, the movable component 3 includes a connecting block 301 fixedly connected to the bottom of the movable frame 202. The connecting block 301 is located at the bottom center of the movable frame 202. A support ring 302 is fixedly connected to the inner bottom of the power distribution cabinet body 1. A second threaded rod 303 is rotatably connected to the inner side wall of the support ring 302. The end of the second threaded rod 303 away from the support ring 302 is rotatably connected to the inner side wall of the power distribution cabinet body 1. The second threaded rod 303 is threadedly connected to the connecting block 301. When the operator rotates the second threaded rod 303, the second threaded rod 303 drives the connecting block 301 to move, thereby driving the movable frame 202 to move synchronously.

[0032] like Figure 1 , Figure 6As shown, a mounting bracket 305 is fixedly connected to the inner bottom of the main body 1 of the distribution cabinet. The mounting bracket 305 is located above the support ring 302. A drive bevel gear 306 is rotatably connected to the inner top of the mounting bracket 305. A driven bevel gear 304 is fixedly connected to one end of the second threaded rod 303 near the support ring 302. The driven bevel gear 304 meshes with the drive bevel gear 306. A rotating disk 307 is fixedly connected to the top of the drive bevel gear 306. When the operator rotates, the rotating disk 307 can be rotated to drive the drive bevel gear 306 to rotate synchronously. Furthermore, the drive bevel gear 306 meshes with the driven bevel gear 304 to drive the driven bevel gear 304 to rotate synchronously, so that the operator can rotate the second threaded rod 303 and improve the operator's operating space.

[0033] like Figure 7 , Figure 8 and Figure 9 As shown, the mounting assembly 4 includes a mounting plate 401 fixedly connected to one end of the adjusting rod 209. A fixing box 402 is fixedly connected to the outer wall of the mounting plate 401. The outer wall of the fixing box 402 is provided with several fixing holes to facilitate the operator to fix electrical components. A guide rail 403 is fixedly connected to the inner wall of the fixing box 402. A first clamping arm 404 is slidably connected to the fixing box 402 through the guide rail 403. A second clamping arm 406 is slidably connected to the fixing box 402 through the guide rail 403. A sliding groove 405 is opened on the outer wall of the first clamping arm 404. The second clamping arm 406 is slidably connected to the first clamping arm 404 through the sliding groove 405. The first clamping arm 404 and the second clamping arm 406 are centrally symmetrically distributed.

[0034] like Figure 7 , Figure 8 and Figure 9 As shown, a first gear 407 is rotatably connected to the outer wall of the adjusting rod 209, and a second gear 408 is rotatably connected to the outer wall of the adjusting rod 209. The first gear 407 and the second gear 408 are fixedly connected. The inner wall of the first clamping arm 404 is provided with teeth, and the second clamping arm 406 is provided with teeth that are centrally symmetrical with the first clamping arm 404. The first clamping arm 404 meshes with the first gear 407 through the teeth, so that when the first gear 407 rotates, it will drive the first clamping arm 404 and the second clamping arm 406 to move relative to each other.

[0035] like Figure 7 , Figure 8 and Figure 9As shown, guide posts 410 are slidably connected to the inner wall of mounting plate 401. There are two guide posts 410. The bottom of the guide posts 410 is fixedly connected to a base plate 409. The two guide posts 410 are symmetrically distributed with respect to the vertical symmetrical surface of the base plate 409. A drive frame 411 is fixedly connected to the top of the base plate 409. The inner wall of the drive frame 411 is provided with teeth. The drive frame 411 meshes with the second gear 408 through the teeth. A spring 412 is fixedly connected to the top of the base plate 409. The end of the spring 412 away from the base plate 409 is fixedly connected to the bottom of the mounting plate 401. In use, the operator places the electrical components on top of the base plate 409. At this time, the base plate 409 moves towards the bottom of the main body 1 of the distribution cabinet due to the weight of the electrical components. The base plate 409 drives the drive frame 411 to move synchronously. The teeth set on the inner side wall of the drive frame 411 drive the second gear 408 to rotate. At the same time, the second gear 408 drives the first gear 407 to rotate synchronously. Since the first clamping arm 404 and the second clamping arm 406 are respectively engaged with the first gear 407, when the first gear 407 rotates with the second gear 408, it will drive the first clamping arm 404 and the second clamping arm 406 to move relative to each other, thereby initially limiting the electrical components so that the operator's hands can be freed to install and fix the electrical components.

[0036] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, during use, the operator starts the motor 217. Driven by the motor 217, the first threaded rod 219 rotates, thereby causing the threaded sleeve 222 to move along the first threaded rod 219. When the threaded sleeve 222 moves, it will drive the two push rods 223 to move synchronously. Since the two push rods 223 are slidably connected to the two rotating rods 221 respectively, when the two push rods 223 move synchronously with the threaded sleeve 222, they will cause the angle between the two rotating rods 221 to change, thereby changing the angle between the two connecting posts 222. 18. Two rotating rods 221 drive two guide rods 203 to rotate, thereby adjusting the angle between the two guide rods 203. When the moving frame 202 moves, it drives the uprights 207 to move synchronously. When the moving frame 202 moves away from the interior of the main body 1 of the distribution cabinet, because the two guide rods 203 are arranged in a trumpet shape, the movement of the moving frame 202 drives the uprights 207 to move synchronously. One end of each upright is located inside a guide groove 204. Therefore, when the uprights 207... During movement, guided by the two guide rods 203, the two columns 207 gradually move away from each other. At this time, the two columns 207 drive the two moving blocks 206 to move synchronously, so that the two moving blocks 206 gradually move away from the outer wall of the fixed rod 205. At the same time, the two ends of the scissor fork structure formed by the interconnection of several connecting rods 211 are respectively located inside the two limiting grooves 208. When the two moving blocks 206 move away from each other, they drive the scissor fork structure formed by the connecting rods 211 to gradually stretch. Since a set of connecting rods 211 is rotatably connected to the outer wall of the adjusting rod 209, the outer wall of the scissor fork structure is provided with multiple adjusting rods 209, and multiple support springs 210 are respectively located between multiple sets of spaced adjusting rods 209. Thus, when the two moving blocks 206 gradually move away from each other, they will drive the scissor fork group formed by multiple connecting rods 211 to stretch, which will further drive the distance between multiple adjusting rods 209 to gradually increase. This will increase the distance between the electrical components set on the adjusting rods 209, so that the operator can observe the gaps between the electrical components and avoid potential hazards between the electrical components.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
