Description

Technical Field

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

[0002] Modular distribution cabinets are widely used in power systems, industrial control, and other fields. They typically contain modular brackets for mounting electrical components such as circuit breakers, relays, and control modules. In existing technology, traditional modular brackets generally use a fixed installation structure, secured to the cabinet body with bolts through pre-drilled connection holes. This fixed connection method results in non-adjustable bracket installation positions and layer spacing, leading to a lack of flexibility in the internal space layout of the distribution cabinet. In practical applications, due to the varying sizes and installation requirements of different electrical modules, fixed modular brackets often struggle to accommodate multiple module specifications. For example, when installing smaller modules, the brackets cannot be adjusted adaptively, resulting in reduced space utilization and wasted space; while installing larger modules may be impossible due to insufficient bracket spacing, affecting the expandability and compatibility of the distribution cabinet. Furthermore, during later maintenance or upgrades, if adjustments to the module layout are needed, the fixed bracket structure often requires re-drilling or replacing the brackets, increasing modification costs and construction difficulty.

[0031] Reference Figures 1 to 6According to a first aspect embodiment of the present invention, a modular low-voltage distribution cabinet includes a cabinet body 100, a first partition 200, multiple module supports 300, and an adjustment structure 400. The cabinet body 100 has a receiving cavity. The first partition 200 is vertically disposed in the receiving cavity and divides the receiving cavity into a first receiving cavity 110 and a second receiving cavity 120. The first receiving cavity 110 and the second receiving cavity 120 are arranged along the width direction of the cabinet body 100. The multiple module supports 300 are spaced apart in the first receiving cavity 110 in the vertical direction. The adjustment structure 400 includes an adjustment guide rail 410 and a sliding component 420. The adjustment guide rail 410 extends in the vertical direction and is disposed on the side wall of the first receiving cavity 110. The sliding component 420 is disposed on the module support 300 and is detachably disposed on the adjustment guide rail 410. The sliding component 420 can slide along the adjustment guide rail 410 to adjust its position. The first cavity 110 is used for wiring, and the module bracket 300 in the second cavity 120 can be slidably adjusted by the sliding component 420 and the adjusting guide rail 410. This allows multiple module brackets 300 to be slidably adjusted in the vertical direction to accommodate different modules according to their size, resulting in strong compatibility and maximizing space utilization to accommodate more modules.

[0032] Specifically, the module bracket 300 is used to support electrical modules, including circuit breakers, instrument units, frequency converters, and other modules. The first partition 200 can divide the receiving cavity of the cabinet 100 into a second cavity 120 and a first cavity 110. The first cavity 110 can be used for wiring, while the second cavity 120 is used to install various modules. The module bracket 300 can be set in pairs or as a whole. The adjusting rail is located on the side wall of the second cavity 120, and one or more can be set. The side of the module bracket 300 is provided with a sliding component 420. It can be detachably connected to the adjustment rail, and its position can be adjusted by sliding after connection. In actual use, if modules of different sizes are needed, multiple module brackets 300 can be slidably adjusted to several spaces with smaller floor heights and several spaces with larger floor heights, and the corresponding size modules can be installed. This can make full use of the internal space of the cabinet 100. In the prior art, the module brackets 300 are fixed. After installing small modules, a lot of space will be wasted. When installing large modules, some module brackets 300 need to be disassembled before they can be installed, resulting in low space utilization. This embodiment can solve the problem of low space utilization.

[0033] Reference Figures 3 to 5According to some embodiments of this utility model, the adjusting guide rail 410 is provided with a guide groove 411, which extends along the extending direction of the adjusting guide rail 410. The guide groove 411 is divided into an inner groove portion 4111 and an outer groove portion 4112 from the inside to the outside. The two inner sidewalls of the outer groove portion 4112 are provided with first guide surfaces 4112a that approach each other in a direction from the outside to the inside. The sliding component 420 can cooperate with the first guide surface 4112a and be engaged in the inner groove portion 4111. Specifically, the first guide surface 4112a can be provided as an inclined surface or an arc surface. The first guide surface 4112a can guide the sliding component 420 to be engaged in the inner groove portion 4111, which facilitates the installation of the module bracket 300. The specific structure of the sliding component 420 is not specifically limited here.

[0034] Reference Figure 5 According to some embodiments of this utility model, the sliding component 420 includes a base 421, two sliders 422, and an elastic element 423. The base 421 is used to connect with the module bracket 300. The two sliders 422 are slidably disposed on opposite sides of the base 421, and the two sliders 422 can slide towards each other or away from each other. An elastic element 423 is provided between the two sliders 422, and the elastic element 423 can drive the two sliders 422 to slide away from each other. Specifically, the sliders 422 and the base 421 can be connected by a sliding structure, which is not specifically limited here. When the sliding component 420 is installed in the guide groove 411, the sliders 422 can abut against the corresponding first guide surface 4112a. The first guide surface 4112a can drive the two sliders 422 to approach each other and compress the elastic element 423. After being inserted into the inner groove 4111, the elastic element 423 can drive the two sliders 422 to spring back away from each other, thereby being inserted into the inner groove 4111, making installation convenient and quick.

[0035] Reference Figure 5 According to some embodiments of this utility model, the base 421 includes a base 4211 and a connecting frame 4212. The connecting frame 4212 is disposed on the side of the base 4211 facing the cabinet 100. The connecting frame 4212 is provided with a sliding hole 4212a extending along the width direction of the guide groove 411. The slider 422 is slidably connected to the sliding hole 4212a, and an elastic element 423 is disposed in the sliding hole 4212a, with one end abutting against one slider 422 and the other end abutting against another slider 422. Specifically, the elastic element 423 can be a spring. The spring can be installed in the slider 422 first, and then the two sliders 422 are respectively inserted into both ends of the slider 422. It is understood that there is a limiting structure between the sliding hole 4212a and the slider 422. The limiting structure can prevent the slider 422 from disengaging from the sliding hole 4212a. The specific structure is not described in detail here. The two sliders 422 can be driven by one elastic element 423, which can save parts, reduce manufacturing costs, and facilitate assembly.

[0036] Reference Figure 5According to some embodiments of this utility model, the slider 422 is provided with a second guide surface 4221 for disassembly. The second guide surface 4221 is close to one side of the module bracket 300 and is used to cooperate with the guide groove 411, so that the two sliders 422 approach each other and are disassembled from the guide groove 411. Specifically, the second guide surface 4221 is inclined towards the side wall of the cabinet 100 in the direction from the outer side to the inner side of the slider 422. When it is necessary to disassemble the module bracket 300, the module bracket 300 can be pulled out by force. In the actual disassembly process, the sliding component 420 moves with force in the direction away from the adjustment track. At this time, the second guide surface 4221 cooperates with the guide groove 411 and guides the two sliders 422 to slide towards each other. Finally, the slider 422 can slide to disengage from the guide groove 411. Since the module bracket 300 only bears the force in the vertical direction, while the disassembly requires the application of a lateral force, the above structure can both ensure that the normal use of the module bracket 300 is not affected and facilitate the disassembly of the module bracket 300.

[0037] Reference Figure 5 According to some embodiments of this utility model, the inner groove 4111 is configured as a T-shaped groove to facilitate engagement with the sliding component 420.

[0038] Reference Figure 5 and Figure 6 According to some embodiments of this utility model, the adjusting guide rail 410 includes a first guide rail seat 412 and a second guide rail seat 413 connected along its thickness direction. The sidewall of the guide groove 411 is disposed on the second guide rail seat 413. The first guide rail seat 412 forms the bottom wall of the guide groove 411. The first guide rail seat 412 and the second guide rail seat 413 are connected by fasteners 414, which can press the slider 422 into the guide groove 411 and lock it in place. Specifically, the first guide rail seat 412 can be configured as a flat plate, and the second guide rail seat 413 is provided with a through hole in the inner sidewall structure of the guide groove 411. When the second guide rail seat 413 covers the first guide rail seat 412, it can cooperate to form the guide groove 411. Fastener 414 can be a bolt. The first guide rail seat 412 can have a threaded hole, and the second guide rail seat 413 can have a through hole corresponding to the threaded hole. The bolt can be inserted into the through hole and threadedly connected to the threaded hole. When fastener 414 is loosened, the bottom wall of guide groove 411 moves away from the second guide rail seat 413, the groove space expands, and sliding component 420 can slide freely along guide groove 411. As fastener 414 is gradually tightened, the bottom wall of guide groove 411 approaches and presses slider 422 into guide groove 411. By adjusting the tightening force of fastener 414, damping can be formed between slider 422 and guide groove 411 to facilitate position adjustment. After position adjustment, fastener 414 can be further tightened, at which point slider 422 can be locked in guide groove 411, and module bracket 300 can be positioned.

[0039] Reference Figure 3According to some embodiments of this utility model, the cabinet 100 is provided with a plurality of first mounting portions 130 arranged at intervals along the front-back direction. The adjusting guide rail 410 can be installed on the corresponding first mounting portion 130 to adjust the front-back position of the module bracket 300. Specifically, the first mounting portion 130 can be provided as a mounting hole, and a plurality of mounting holes can be preset. The adjusting guide rail 410 can be connected to the mounting hole at the desired position through fasteners 414 to adjust the front-back position of the module bracket 300.

[0040] According to some embodiments of this utility model, the module bracket 300 is provided with a plurality of second mounting portions arranged at intervals along the front and rear. The sliding component 420 can be mounted on the corresponding second mounting portion to adjust the front and rear position of the module bracket 300. Specifically, the second mounting portion can also be provided as mounting holes, with a plurality of mounting holes arranged at intervals along the front and rear direction of the module bracket 300. The sliding component 420 can be connected to the required mounting hole by a fastener 414, thereby adjusting the front and rear position of the module bracket 300.

[0041] Reference Figure 1 According to some embodiments of this utility model, it also includes a panel 140, which is disposed on the front side of the second cavity 120. The panel 140 is provided with a plurality of clearance holes 141 for instrument exposure. Specifically, the panel 140 can close the second cavity 120 to protect the wiring, and can also reserve clearance holes 141 for instrument display.
