[0002] The distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection. Since multiple groups of equipment need to be installed inside the high and low voltage distribution box, they need to be installed in layers using partitions. Different equipment has different heights, so the position of the partitions needs to be reasonably planned.

[0003] After searching, the utility model patent with publication number CN219918083U discloses a multi-compartment high and low voltage distribution box that is easy to adjust, including a cabinet, the front of which is hinged with a door by hinges, and the inner cavity of the cabinet is provided with multiple groups of partitions from top to bottom. The utility model drives the worm wheel to rotate through the worm, and then the worm wheel drives the gear to rotate through the rotating shaft, so that the gear moves up and down in the tooth groove on the surface of the fixed rod, thereby adjusting the partition up and down. The worm and the worm wheel have a self-locking function. Only when the worm is rotated can the worm wheel move up and down on the surface of the fixed rod, which improves the safety of the device.

[0004] However, in actual applications, the device cannot adjust the number of partitions. When the electronic components are large in size, multiple partitions will be stacked together, wasting space. When disassembling or repairing electronic components, it is necessary to go deep into the cabinet, where the operating space is small and inconvenient. Utility Model Content

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 3 As shown, a multi-compartment high and low voltage distribution box that is easy to adjust includes a box body 1, a box door 2 is installed at the front end of the box body 1, and a plurality of partitions 3 are movably arranged inside. Limiting columns 4 are fixedly connected at the four corners of the bottom of the box body 1, and fixing columns 5 are symmetrically fixedly connected on both sides of the inside. Gaps are provided between the tops of the limiting columns 4 and the fixing columns 5 and the top surface of the box body 1, and L-shaped plates 10 that match the limiting columns 4 are fixedly connected to the four corners of the bottom of the partition 3, and the L-shaped plate 10 is clamped on the outside of the limiting columns 4, and a rack 6 is installed on one side of the fixing column 5. Slots that match the limiting columns 4 and the fixing columns 5 are opened on both sides of the partition 3, and a positioning component is provided at the lower part of the partition 3.

[0024] There is a gap between the top of the limiting column 4 and the fixing column 5 and the top surface of the box body 1, so that when the partition 3 moves to the top of the limiting column 4, the partition 3 can be taken out from the box body 1. Similarly, a new partition 3 can be installed into the box body 1 through the gap, so that the number of partitions 3 can be adaptively adjusted according to usage requirements. The L-shaped plate 10 cooperates with the limiting column 4 so that the partition 3 can only move in the vertical direction to prevent the partition 3 from tilting.

[0025] like Figure 3 , Figure 4 and Figure 5As shown, the positioning assembly includes a protective shell 11 of a cross-shaped structure, a screw rod 12 is installed through the front end of the protective shell 11, one end of the screw rod 12 is fixedly connected to a hand wheel 13, and the other end is rotatably installed with a trapezoidal block 14 inside the protective shell 11, a nut threadedly connected to the screw rod 12 is fixedly connected to the front end of the protective shell 11, two fixing plates 15 are symmetrically fixed inside the protective shell 11, and connecting rods 16 are penetrated on both sides, one end of the connecting rod 16 is fixedly connected to a positioning block 17, and the other end is fixedly connected to a limiting plate 18 inside the protective shell 11, One side of the positioning block 17 is provided with teeth meshing with the rack 6, and the bottom of the partition 3 is fixedly connected to a limit frame 21 sleeved on the outside of the positioning block 17, one side of the limit plate 18 is fixedly connected to a rectangular column 19 penetrating through the fixed plate 15, and the other side is provided with a spring 20 sleeved on the outside of the connecting rod 16, one end of the rectangular column 19 is an inclined surface, and the inclined surface abuts against the side surface of the trapezoidal block 14, the inner upper part of the protective shell 11 is fixedly connected to a limit strip 22, and the top surface of the trapezoidal block 14 is provided with a limit groove adapted to the limit strip 22.

[0026] The screw rod 12 is rotated by the hand wheel 13, so that the screw rod 12 drives the trapezoidal block 14 to move forward, and the trapezoidal block 14 squeezes the rectangular columns 19 on both sides outward, prompting the limit plate 18 to drive the connecting rod 16 and the positioning block 17 to move outward, and the limit plate 18 squeezes the spring 20, and stops when the teeth on the positioning block 17 mesh with the rack 6, so as to fix the partition 3. When the partition 3 needs to be moved, the hand wheel 13 is rotated in the opposite direction, so that the trapezoidal block 14 moves backward, and the positioning block 17 is separated from the rack 6 under the action of the spring 20, and the partition 3 can be moved up and down along the limit column 4.

[0027] like Figure 2 and Figure 4 As shown, two I-shaped guide rails 7 are fixedly connected to the top of the partition 3, and a mounting plate 8 for mounting electronic components is provided above the guide rails 7. Positioning strips 9 adapted to the guide rails 7 are fixedly connected to the bottom of the mounting plate 8 on both sides of the guide rails 7. Through holes corresponding to the positions are opened on both sides of the mounting plate 8 and the front end of the partition 3, and positioning pins 23 are installed in the through holes. A lower ear plate 24 is fixedly connected to the top of the front end of the partition 3, and an upper ear plate 25 corresponding to the position of the lower ear plate 24 is fixedly connected to the lower part of the rear end of the mounting plate 8.

[0028] When disassembling or overhauling the electronic components on the mounting plate 8, remove the positioning pin 23, and move the mounting plate 8 outward along the guide rail 7, so that some of the electronic components are moved to the outside of the box body 1, which is convenient for disassembly or overhaul. When the upper ear plate 25 abuts against the lower ear plate 24, it stops. At this time, 2 / 3 of the mounting plate 8 is located outside the box body 1, which can provide sufficient space for disassembly or overhaul. The lower ear plate 24 can limit the distance that the mounting plate 8 moves outward. After disassembly or overhaul is completed, push the mounting plate 8 backward so that the center lines of the through holes on the mounting plate 8 and the partition 3 coincide, and insert the positioning pin 23 in the through hole to fix the mounting plate 8.

[0029] In specific use, the installation and removal of the partition 3 can be achieved through the gap between the top of the limiting column 4 and the fixing column 5 and the top surface of the box body 1, and the number of partitions 3 can be adjusted according to the use requirements. The position of the two positioning blocks 17 can be adjusted by turning the hand wheel 13. When the teeth on the positioning block 17 are engaged with the rack, the partition 3 can be fixed. When the positioning block 17 is separated from the rack 6, the position of the partition 3 can be adjusted. Remove the positioning pin 23 and move the mounting plate 8 outward along the guide rail 7, so that some electronic components are moved to the outside of the box body 1, which is convenient for disassembly or maintenance.
