[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 and 3 -4, an embodiment of the utility model: a high and low voltage switch cabinet, including a cabinet body 1, a symmetrical slide rail 2 is fixedly connected to one side of the inner wall of the cabinet body 1, a sliding plate 3 is slidably connected to the outer wall of the two slide rails 2, a plurality of sliding blocks 4 are slidably connected inside the sliding plate 3, a fixing bolt 5 is threadedly connected inside the slide rail 2 and the sliding plate 3, a limit plate 6 is fixedly connected directly below the slide rail 2, a plurality of clamping blocks 7 are fixedly connected to the outer wall of the limit plate 6, one side of the outer wall of the limit plate 6 is in contact with one side of the outer wall of the classification nameplate 8, a symmetrical buckle 9 is fixedly connected to the outer wall of the classification nameplate 8, the buckle 9 is clamped and connected with the clamping block 7, and the classification nameplate 8 is fixedly connected to the outer wall. A spring 10 is fixedly connected to one side of the outer wall of the nameplate 8, and a stabilizing block 11 is fixedly connected to one end of the spring 10. The outer wall of the stabilizing block 11 is slidably connected to the inner wall of the limiting plate 6. The inner wall of the cabinet 1 is slidably connected to the mounting plate 12, and a wire management component 13 is arranged on the upper surface of the mounting plate 12; the wire management component 13 includes a winding roller 1301, the winding roller 1301 is slidably connected to the upper surface of the mounting plate 12, the lower surface of the winding roller 1301 is fixedly connected to a limiting bolt 1302, the limiting bolt 1302 is slidably connected to the inner wall of the mounting plate 12, and the outer wall of the limiting bolt 1302 is threadedly connected to a butterfly nut 1303;

[0026] Specifically, by installing the electronic components on the outer walls of multiple sliding blocks 4 respectively, it is convenient for the staff to adjust the height by sliding the sliding plate 3 to meet the needs of arranging different wire harnesses. In order to better fix the sliding plate 3, the fixing bolt 5 is passed through the sliding plate 3 and installed inside the slide rail 2. In this way, the staff can easily fix the sliding plate 3, making it more stable when arranging the wire harness. Next, the wire harness is placed in the groove of the limit plate 6. Then the classification nameplate 8 is driven and engaged on the outer wall of the card block 7 to fix the wire harness. The reaction force of the spring 10 pushes the stabilizing block 11 to resist the wire harness, thereby achieving the effect of classifying and arranging the wire harness. In this way, the wire harness can be orderly arranged according to its type, purpose, etc. In addition, for the excess wire harness, it can be wound on the outer wall of the winding roller 1301. The butterfly nut 1303 can fix the position of the winding roller 1301 to prevent it from displacement. This method can effectively prevent the wire harness from falling off due to pulling, and further improve the effect of wire harness arrangement.

[0027] Reference Figure 1-2A plurality of support rods 14 are fixedly connected to the upper surface of the cabinet 1, and a top plate 15 is fixedly connected to the upper surface of the plurality of support rods 14; a symmetrical fan 16 is arranged inside the cabinet 1, and a dust cover 17 is slidably connected to the outer wall of the fan 16, and the lower surface of the dust cover 17 is fixedly connected to the upper surface of the cabinet 1;

[0028] Specifically, by starting the fan 16, the heat inside the cabinet 1 can be effectively discharged to prevent the cabinet 1 from overheating, thereby protecting the electronic components inside the cabinet 1 from damage. At the same time, the design of the dust cover 17 is also indispensable. It can effectively block impurities such as dust and insects from entering the cabinet 1, protecting the electronic components from pollution and damage. This design is particularly important for cabinets 1 used in harsh environments. It can ensure that the interior of the cabinet 1 is always kept clean and extend the service life of the electronic components. In addition, the design of the top plate 15 also takes safety into consideration. It can effectively prevent falling objects from high altitude from damaging the fan 16, thereby affecting the normal use of the cabinet 1. This design fully takes into account various potential safety risks, reduces the impact of external factors on the cabinet 1 by adding the top plate 15, and improves the reliability and safety of the cabinet 1.

[0029] Reference Figure 1-2 5. A mounting frame 19 is fitted on one side of the outer wall of the cabinet 1, and a dust screen 20 is fixedly connected inside the mounting frame 19; a limit rod 21 is fixedly connected inside the mounting frame 19, and a spring 22 is sleeved on the outer wall of the limit rod 21; both ends of the spring 22 are fixedly connected with a shift block 23, and a protrusion 24 is fixedly connected to the outer wall of the shift block 23. The outer wall of the shift block 23 is slidably connected to the inside of the mounting frame 19, and the protrusion 24 is snap-connected to the inside of the cabinet 1; a hollow plate 18 is fixedly connected to the upper part of the inner wall of the cabinet 1, and the hollow plate 18 is arranged directly below the fan 16, and the dust cover 17 is arranged directly below the top plate 15;

[0030] Specifically, the heat inside the cabinet 1 is extracted through the fan 16, so that it can be exchanged with the outside air to achieve the purpose of cooling. In the process of air intake, it can be filtered through the dustproof net 20 inside the installation frame 19 to effectively prevent dust from entering the cabinet 1. Such a design not only ensures the entry of fresh air, but also avoids the invasion of dust, so that the inside of the cabinet 1 always maintains a clean and hygienic environment. However, after long-term use, a large amount of dust will inevitably adhere to the surface of the dustproof net 20, affecting its filtering effect. At this time, the dustproof net 20 needs to be cleaned. In order to complete this task conveniently and quickly, by pressing the dial block 23, it slides on the outer wall of the limit rod 21. When the dial block 23 slides to a certain position, it will squeeze the spring 22, causing the spring 22 to deform. As the spring 22 deforms, the protrusion 24 will be separated from the inside of the cabinet 1. At this time, the dustproof net 20 can be easily removed for cleaning. After cleaning, follow the reverse steps to install it back to its original position.

[0031] Working principle: When it is necessary to organize the wiring harness inside the high and low voltage switch cabinet, the electronic components are respectively installed on the outer walls of multiple sliding blocks 4, and the height is adjusted by sliding the sliding plate 3. The fixing bolts 5 are passed through the sliding plate 3 and installed inside the slide rail 2, so as to facilitate the fixing of the sliding plate 3. At this time, the wiring harness is placed in the groove of the limit plate 6, and the classification nameplate 8 drives the buckle 9 to engage with the outer wall of the card block 7 to fix the wiring harness. The reaction force of the spring 10 pushes the stabilizing block 11 to resist the wiring harness, so as to achieve the effect of classifying and arranging the wiring harness. The excess wiring harness is wound around the outer wall of the winding roller 1301 to prevent it from falling off by pulling the wiring harness. The butterfly nut 1303 can fix the position of the winding roller 1301 to prevent displacement. Multiple sets of wire management components 13 can be installed according to usage requirements. At this time, the heat inside the cabinet 1 is discharged from the inside of the cabinet 1 by starting the fan 16, thereby preventing the cabinet 1 from overheating and causing damage to the electronic components inside the cabinet 1. The dust cover 17 can block dust and insects from entering the inside of the cabinet 1, and the top plate 15 can prevent falling objects from high altitude from damaging the fan 16 and affecting the use effect. While the heat inside the cabinet 1 is extracted out of the cabinet 1 by the fan 16, the dust can be filtered through the dust net 20 inside the installation frame 19 to allow fresh air to enter the inside of the cabinet 1 for cooling. After long-term use, a large amount of dust will adhere to the surface of the dust net 20, affecting its use. At this time, by pressing the shift block 23 to slide on the outer wall of the limit rod 21 and then squeezing the spring 22, the protrusion 24 is separated from the inside of the cabinet 1, thereby achieving the effect of quickly installing and removing the dust net 20 for cleaning.
