A pulley 35 is fixedly connected to the surface of each plug block 34. A placement plate 36 is movably connected to the surface of each plug block 34. A pulley 37 is fixedly connected to the bottom of the placement plate 36. A plug rod 38 is inserted into the interior of each slider 32. A heat dissipation and dust prevention structure 4 is provided on the surface of the housing 1, including a heat dissipation vent 41. A mounting bracket 42 is fixedly connected to the inner wall of the heat dissipation vent 41. A fan 43 is fixedly connected to the surface of the mounting bracket 42. A dustproof mesh 44 is bolted to the outer surface of the heat dissipation vent 41, and a dustproof net 44 is bolted to the inner surface of the heat dissipation vent 41. It has a dustproof net 45 and an adjustment structure 3. The position of the slider 32 on the vertical rod 31 is adjusted and fixed by the insertion rod 38. The spacing of multiple sets of placement plates 36 can be freely adjusted as needed. The insertion block 34 and the slider 32 are inserted into each other through the square groove 2. After the equipment is installed on the placement plate 36, when maintenance is needed, the placement plate 36 can be pulled out directly through the pulley 1 35 and pulley 2 37, which is convenient for maintenance of the equipment on the placement plate 36. It is easy to use. A heat dissipation and dustproof structure 4 is set up. The lower set of fans 43 draws air into the box 1, and the upper set of fans 43 blows air out of the box 1. The equipment inside the box 1 is cooled by active heat dissipation. At the same time, dust is filtered by dustproof net 1 44 and dustproof net 2 45. When there is too much dust, the bolts can be removed and the dustproof net can be replaced directly. The active heat dissipation method increases the heat dissipation efficiency and prevents dust from entering.

[0024] Furthermore, the inner wall of the housing 1 is provided with four sets of square grooves, and four sets of vertical rods 31 are fixedly connected to the inner wall of the four sets of square grooves. The slider 32 is slidably connected in the square groove. The surface of the vertical rod 31 is provided with multiple sets of circular grooves from top to bottom. The surface of the slider 32 is provided with circular grooves. The insertion rod 38 is inserted into the circular grooves and circular grooves. The position of the slider 32 on the vertical rod 31 is adjusted and the position is fixed by the insertion rod 38. The spacing of multiple sets of placement plates 36 can be freely adjusted as needed.

[0025] Furthermore, two sets of sliders 32, baffles 33, plug blocks 34, pulley one 35, pulley two 37 and two sets of plug rods 38 constitute an adjustment assembly. Two sets of adjustment assemblies are symmetrically arranged about the box 1. The two sets of adjustment assemblies and a set of placement plates 36 constitute a loading assembly. Three loading assemblies are arranged from top to bottom. The positions of the sliders 32 on both sides on the vertical rod 31 are adjusted and fixed by the plug rods 38, thereby adjusting the spacing of the three loading assemblies.

[0026] Furthermore, the surface of the plug-in block 34 is provided with two sets of square grooves, and the slider 32 is movably connected in the square grooves. The cross sections of the baffle 33 and the plug-in block 34 are both triangular. The inclined surfaces of the baffle 33 and the plug-in block 34 are in contact. The plug-in block 34 and the slider 32 are plugged into each other through the square grooves. The baffle 33 and the plug-in block 34 abut against each other under the action of gravity, and the plug-in block 34 is installed on the slider 32, thereby installing the equipment on the placement plate 36.

[0027] Furthermore, the top of the plug-in block 34 is provided with a sliding groove 1, and the bottom of the placement plate 36 is provided with a sliding groove 2. The first pulley 35 is slidably connected in the sliding groove 2, and the second pulley 37 is slidably connected in the sliding groove 1.

The fan blade is driven to rotate by the motor to actively dissipate heat from the inside of the cabinet 1.

[0029] Furthermore, the blades of the two sets of fans 43 rotate in opposite directions. The lower set of fans 43 draws air into the housing 1, while the upper set of fans 43 blows air out of the housing 1.

[0030] Working principle: During installation, adjust the position of slider 32 on vertical rod 31 according to the size and quantity of equipment, and fix the position through insertion rod 38. Then adjust the spacing of multiple sets of placement plates 36. Insert block 34 and slider 32 are inserted into each other through square groove 2. Baffle 33 and insertion block 34 abut against each other under the action of gravity, install insertion block 34 on slider 32, and then install equipment on placement plate 36. When maintenance is required, placement plate 36 can be pulled out directly through pulley 1 35 and pulley 2 37 to facilitate maintenance of equipment on placement plate 36. The motor drives the fan blades to rotate, actively cooling the inside of the box 1. The lower set of fans 43 draws air into the box 1, and the upper set of fans 43 blows air out of the box 1. At the same time, dust is filtered through dust screen 1 44 and dust screen 2 45. When there is too much dust, the bolts can be removed directly to replace the dust screen.
