Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet with layered cable management channels. Background Technology

[0002] Distribution cabinets are an indispensable component of power systems, primarily responsible for accurately distributing electrical energy to various devices or areas that require power. They play a crucial role in power systems, ensuring the stable and safe transmission of electrical energy.

[0003] The existing power distribution cabinets still have some shortcomings in actual use: 1. Traditional distribution cabinets often use cable ties, cable trays, and other methods to fix cables. These methods have problems such as insecure fixing and difficulty in disassembly. When it is necessary to replace or adjust the position of cables, a lot of manpower and resources are often required. In addition, these fixing methods are difficult to adapt to different specifications and quantities of cables, which limits the versatility and expandability of distribution cabinets.

[0004] 2. Once the wiring harness layout of a traditional distribution cabinet is determined, it is difficult to make adjustments. With the upgrading of power equipment and the increase in the number of cables, the original wiring harness layout may not be able to meet the new requirements, leading to problems such as cable crossing and confusion, which further increases the difficulty of maintenance and operational risks. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of traditional power distribution cabinets, which often use cable ties, cable trays and other methods to fix cables. These methods are not secure and are difficult to disassemble. With the upgrading of power equipment and the increase in the number of cables, the original wire harness layout may not be able to meet the new requirements, resulting in the problem of cables crossing and messing up. Once the wire harness layout of the traditional power distribution cabinet is determined, it is difficult to adjust it. Therefore, a power distribution cabinet with layered cable trays is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A power distribution cabinet with layered cable management channels includes a power distribution cabinet body. Two vertical rods are fixedly installed on one side of the inner wall of the power distribution cabinet body by bolts. A horizontal rod is provided between the two vertical rods. A horizontal plate is fixedly installed on one side of the power distribution cabinet body by bolts, and the horizontal plate is located below the horizontal rod. An outer ring is provided on one side of the horizontal plate, and an inner ring slides through the outer ring.

[0007] In one possible design, multiple mating grooves are provided on the same side of both vertical bars, and mating blocks are provided at both ends of the horizontal bar. The mating blocks are inserted into the mating grooves and engage downwards.

[0008] In one possible design, the crossbar has multiple arc-shaped grooves and multiple locking grooves, and the arc-shaped grooves and locking grooves are connected. The connecting wire passes through the arc-shaped grooves and enters the locking grooves for placement.

[0009] In one possible design, the inner wall of one side of the horizontal plate is provided with a plurality of first slots, a nut is fixedly connected to one side of the outer ring, a lead screw is internally threaded to the nut, a movable plate is fixedly connected to one end of the lead screw, a locking strip is fixedly connected to one side of the movable plate, and the movable plate slides inside the horizontal plate and engages with the first slots through the locking strip. When the nut is rotated, the locking strip is released from the engagement with the first slots, allowing the movable plate to slide and adjust inside the horizontal plate.

[0010] In one possible design, the outer ring has grooves at its top and bottom, and the inner ring slides between the two grooves. Both ends of the inner ring are rotatably connected to rotating shafts, and both ends of the rotating shafts are connected to the two grooves. The outer walls of the two rotating shafts are fixedly fitted with locking blocks. Both ends of the locking blocks are fixedly connected to the inner ring with torsion springs, and the torsion springs are fitted on the outer walls of the rotating shafts. The inner ring has two limiting grooves, and the outer walls of the two rotating shafts are fixedly connected with limiting plates, which rotate within the limiting grooves.

[0011] In one possible design, the top of the outer ring is provided with two through slots, and two rotating shafts pass through the two through slots to the top of the outer ring.

[0012] In one possible design, the outer wall of the outer ring is provided with a plurality of second slots, and two locking blocks engage with the corresponding second slots.

[0013] In this application, after the main body of the distribution cabinet is installed in its location, the connecting wires are threaded into the main body of the distribution cabinet. According to the unified planning of the device connecting wires, multiple connecting wires are grouped together to form a wire harness, which is then uniformly passed through the inner and outer rings of the plug-in mating mechanism. Then, the bundled connecting wires are passed one by one through the corresponding locking slots to connect with the relevant devices. When the connecting wires pass through the inner and outer rings of the plug-in mating mechanism, the inner ring is pushed to slide within the outer ring according to the number of bundled connecting wires, causing the inner and outer rings to bind the wire harness. As the inner ring slides and binds within the outer ring, the locking blocks at both ends of the inner ring slide on the second locking slot, thereby engaging the locking blocks with the second locking slot. When it is necessary to expand the ring formed by the inner and outer rings, the mechanism is rotated... A rotating shaft drives the locking block to rotate, releasing the locking block from the second locking slot. The rotation of the shaft also causes the torsion spring to twist, simultaneously causing the limiting plate to rotate within the limiting slot. At this point, the inner ring can be pulled out, sliding between the two grooves. When the inner and outer rings expand to a certain extent, the rotation of the shaft is released. The torsion of the torsion spring causes the locking block to engage in the second locking slot, and the limiting plate rotates within the limiting slot, forming a blocking limit. A single connecting wire passes through the arc-shaped groove in the crossbar and enters the locking groove, thus limiting the connecting wire. Simultaneously, the height of the crossbar on the two vertical bars can be adjusted by engaging the mating blocks in the corresponding mating grooves on the vertical bars.

[0014] Beneficial effects: In this utility model, the power distribution cabinet with layered cable management channels can accommodate single connecting wires through arc-shaped grooves and locking grooves. At the same time, the horizontal bar can be adjusted on the two vertical bars, making it more flexible to use. The height adjustment can also coordinate the direction of the connecting wires and electrical components, making the direction of the connecting wires more regular and orderly. In this utility model, the power distribution cabinet with layered cable management channels has a sliding plug-in connection between the inner and outer rings. With the help of a self-locking mechanism composed of a rotating shaft, a locking block, and a torsion spring, the diameter of the cable harness can be infinitely adjusted to meet the fixing requirements of cable harnesses of different specifications. The design of rotating the rotating shaft to release the locking makes the cable harness expansion operation without additional tools, making the operation more convenient. This invention utilizes innovative combinations such as mechanical self-locking, layered limiting, and modular design to achieve standardized, adjustable, and intelligent cable management while maintaining structural compactness. It is particularly suitable for complex cabling scenarios such as data centers and industrial automation. Attached Figure Description
