Description

A modular nested LCP cabinet that is easy to assemble and disassemble Technical Field

[0001] This utility model relates to the field of LCP cabinet installation technology, and in particular to a modular nested LCP cabinet that is easy to assemble and disassemble. Background Technology

[0002] LCP cabinets are key equipment used in the industrial field for power distribution, equipment control and automation system management. Their core function is to achieve centralized control and protection of motors, lighting systems, production line equipment and other electrical components by integrating circuit breakers, contactors, relays, PLCs, frequency converters and other electrical components.

[0003] Existing LCP cabinets have fixed rear panel connections and contain a large number of components and terminals, resulting in limited operating space for component installation. Therefore, an LCP cabinet with easily removable rear panel is needed to expand the operating space for staff. In addition, dust filters at the ventilation openings accumulate dust over time, and a large amount of dust can affect heat dissipation efficiency. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a modular nested LCP cabinet that is easy to assemble and disassemble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular nested LCP cabinet that is easy to assemble and disassemble includes a base, two side plates fixedly mounted on the base, a top plate fixedly mounted on the two side plates, sliders fixedly connected to each side plate, a rear baffle slidably connected to the two sliders, multiple connecting blocks fixedly mounted on the two side plates, multiple slots on each connecting block, mounting blocks slidably connected to each slot, threaded rods threadedly connected to each mounting block, threaded rods rotatably connected to the slots, and threaded rods connected to each other via a belt drive assembly, mounting openings matching the mounting blocks on the rear baffle, each mounting block slidably connected to the mounting opening, and cleaning components mounted on each of the two side plates.

[0007] Preferably, the cleaning assembly includes a vent on the side plate, a dustproof net is fixedly installed inside the vent, two support plates are fixedly installed on the side plate, and the two support plates are respectively installed at the upper and lower ends of the dustproof net. The two support plates are rotatably mounted with a threaded rod, and the threaded rod is threadedly connected to a cleaning block. A control mechanism for controlling the rotation of the threaded rod is installed on the rear baffle.

[0008] Preferably, the control mechanism includes a rack fixedly mounted on the rear baffle, a rotating shaft rotatably connected to the side plate, a spur gear fixedly mounted on one end of the rotating shaft, the spur gear meshing with the rack, a bevel gear one fixedly mounted on the other end of the spur gear, and a bevel gear two fixedly mounted on one end of the threaded rod two, the bevel gear one meshing with the bevel gear two.

[0009] Preferably, a knob is fixedly installed on one end of one of the threaded rods, and a rubber sleeve is threaded onto the knob.

[0010] Preferably, the mounting block is square-shaped and the slot is also square-shaped, with the mounting block matching the slot.

[0011] Preferably, the two support plates are jointly fixedly mounted with a slide rod, and the cleaning block is slidably connected to the slide rod.

[0012] 1. Compared with the prior art, the beneficial effects of this utility model are: by sliding the rear baffle on the slider, the rear baffle can be easily disassembled by sliding it out of the slider. At the same time, the threaded rod drives the mounting block to slide into the mounting opening, which can stabilize the rear baffle and prevent it from shaking. During disassembly, the threaded rod can be easily loosened by rotating it in the opposite direction. The convenient installation and disassembly of the rear baffle allows the staff to operate from behind the LCP cabinet, greatly expanding the operating space.

[0013] 2. When sliding down through the rear baffle, the rack drives the spur gear to rotate, and with the cooperation of bevel gear one and bevel gear two, it drives the threaded rod two to rotate, so that the cleaning block can clean the dust screen, which can prevent a large amount of dust from adhering to the dust screen and ensure heat dissipation efficiency.

[0020] Referring to Figures 1-5, a modular nested LCP cabinet that is easy to assemble and disassemble includes a base 1. Two side plates 2 are fixedly installed on the base 1. A top plate is fixedly installed on both side plates 2. A slider 3 is fixedly connected to each side plate 2. A rear baffle 4 is slidably connected to both sliders 3. Multiple connecting blocks 5 are fixedly installed on both side plates 2. Multiple slots are opened on the connecting blocks 5. Mounting blocks 6 are slidably connected to each slot. The mounting blocks 6 are always slidably connected to the slots and will not leave the slots. Threaded rods 7 are threadedly connected to the mounting blocks 6. Threaded rods 7 are rotatably connected to the slots. Threaded rods 7 are connected to each other through a belt drive assembly 8. The belt drive assembly 8 consists of two pulleys and a belt body. Mounting openings 9 that match the mounting blocks 6 are opened on the rear baffle 4. Each mounting block 6 is slidably connected to the mounting opening 9. Cleaning components are installed on both side plates 2.

[0021] Through the slider 3 on the side plate 2, the rear baffle 4 can slide directly from the top onto the base 1 to complete the initial installation. Then, by rotating the knob 19, the threaded rod 7 is rotated. As the threaded rod 7 rotates, it can drive another threaded rod 7 to rotate through the belt drive assembly 8. This causes the two threaded rods 7 to drive the two mounting blocks 6 to slide in the slots, so that the two mounting blocks 6 enter the two mounting ports 9. After completion, the baffle 4 is stable.

[0022] The cleaning assembly includes a vent on the side plate 2, a dustproof net 10 fixedly installed inside the vent, two support plates 11 fixedly installed on the side plate 2, and the two support plates 11 are respectively installed at the upper and lower ends of the dustproof net 10. The two support plates 11 are rotatably mounted with a threaded rod 12, and the threaded rod 12 is threadedly connected to a cleaning block 13. A control mechanism for controlling the rotation of the threaded rod 12 is installed on the rear baffle 4.

[0023] The rotation of the threaded rod 12 can drive the cleaning block 13 to slide, thereby enabling the cleaning block 13 to clean the dust on the dustproof net 10 and effectively prevent dust accumulation.

[0024] The control mechanism includes a rack 16 fixedly mounted on the rear baffle 4, a rotating shaft 14 rotatably connected to the side plate 2, a spur gear 15 fixedly mounted on one end of the rotating shaft 14, the spur gear 15 meshing with the rack 16, the distance between the connecting block 5 and the rear baffle 4 is sufficient, the rack 16 will not contact the connecting block 5 when it descends, and there will be no work interference, the other end of the spur gear 15 is fixedly mounted with a bevel gear 17, and a bevel gear 18 is fixedly mounted on one end of the threaded rod 12, the bevel gear 17 meshing with the bevel gear 18;

[0025] When the rear baffle 4 is installed by sliding down or removed by lifting up, the rack 16 on it drives the meshing spur gear 15 to rotate, which in turn drives the rotating shaft 14 to rotate. This causes the rotating shaft 14 to drive the bevel gear 17 to rotate, and then drives the meshing bevel gear 18 to rotate, which in turn drives the threaded rod 12 fixedly installed on the bevel gear 18 to rotate.

[0026] A knob 19 is fixedly installed on one end of one of the threaded rods 7. A rubber sleeve is fitted on the threaded part of the knob 19. The threaded rod 7 can be rotated quickly by rotating the knob 19. After long-term use, the rubber sleeve on the knob 19 needs to be replaced. The rubber sleeve on the threaded part can be quickly replaced by the staff. The mounting block 6 is square in shape and the groove is also square in shape. The mounting block 6 matches the groove and can slide stably in the groove without shaking. The two support plates 11 are fixedly installed with a slide rod 20. The cleaning block 13 is slidably connected to the slide rod 20. The slide rod 20 has a limiting and stabilizing function and can prevent the cleaning block 13 from shaking when moving.

[0027] In this utility model, the working principle is as follows: the rear baffle 4 can slide directly from the top onto the base 1 via the slider 3 on the side plate 2 to complete the initial installation. Then, by rotating the knob 19, the threaded rod 7 is rotated. Due to the rotation of the threaded rod 7, the other threaded rod 7 can be rotated through the belt drive assembly 8. This causes the two threaded rods 7 to slide the two mounting blocks 6 in the slots, allowing the two mounting blocks 6 to enter the two mounting ports 9. After the baffle 4 is completed, it is stable. When the rear baffle 4 slides down for installation or rises for disassembly, the rack 16 on it drives the meshing spur gear 15 to rotate. This drives the rotating shaft 14 to rotate, which in turn drives the bevel gear 17 to rotate and the meshing bevel gear 18 to rotate. This causes the threaded rod 12, which is fixedly mounted on the bevel gear 18, to rotate. The rotation of the threaded rod 12 causes the cleaning block 13 to slide, allowing the cleaning block 13 to clean the dust on the dustproof net 10, effectively preventing dust accumulation.
