[0023] Example 3: Please refer to Figure 3 , Figure 7 and Figure 8, this embodiment further explains other embodiments. The cleaning mechanism shown in the figure includes a baffle 24 slidably mounted on the bottom of the cabinet 1. A cavity is provided at the bottom of the cabinet 1 for the baffle 24 to limit the sliding movement. Two symmetrically distributed guide rods 38 are fixedly mounted on the bottom of the cabinet 1. The guide rods 38 slide through the baffle 24 to provide guidance and support for the movement of the baffle 24. A plurality of equidistantly distributed sealing plates 25 are slidably mounted on the top of the baffle 24. A sliding cavity is provided at the top of the baffle 24 for the sealing plate 25 to limit the sliding movement. Two symmetrically distributed support rods 26 are fixedly mounted on the top of the sealing plate 25. The support rods 26 slide through the baffle 24. A limit plate 27 is fixedly mounted between the two support rods 26. Two symmetrically distributed first tension springs 28 are fixedly mounted between the top of the limit plate 27 and the bottom of the baffle 24. A first cleaning hole is provided at the bottom of the cabinet 1 for the sealing plate 25 to limit the insertion. The left side of the first cleaning hole is connected to the left side of the sealing plate 25. The left side is a sloped structure, so that when the baffle 24 drives the sealing plate 25 to move, the sealing plate 25 can move along the slope of the first cleaning hole, so that the sealing plate 25 can be received in the sliding cavity of the baffle 24. A second cleaning hole corresponding to the first cleaning hole is provided on the top of the baffle 24. When the first cleaning hole of the cabinet 1 is aligned with the second cleaning hole on the baffle 24, the staff can discharge the dust in the cabinet 1 downward from the first cleaning hole and the second cleaning hole, thereby improving the convenience of dust cleaning. A driven rod 29 is fixedly installed at the bottom of the positioning block 8 located at the bottom of the mounting plate 3, and a driven gear 30 is fixedly installed at the bottom end of the driven rod 29. When the mounting plate 3 swings, the driven rod 29 can be driven to rotate by the positioning block 8. The driven gear 30 is located in the cavity of the cabinet 1. A rack 31 matching with the driven gear 30 is provided on the outer side of the baffle 24, so that when the driven rod 29 rotates, the rack 31 can be driven to move by the driven gear 30 to realize the movement of the baffle 24.

[0024] Working principle: first, the staff opens the cabinet door 2, and drives the two buckle plates 13 to rotate with the sleeve rod 12 as the fulcrum through the pull rod 15, so that the buckle plate 13 is away from the mounting plate 3, and uses the rebound force of the arc spring 11 to make the arc spring 11 push the mounting plate 3 to move, and the mounting plate 3 drives the positioning block 8 to rotate along the inner side of the U-shaped plate 9, so that the mounting plate 3 swings to the outside of the cabinet 1 and contacts with the limit spring plate 34. Then, the staff inserts the electrical equipment into the equipment slot 7 of the positioning plate 6, so that the bottom of the electrical equipment contacts with the two brackets 16 under the equipment slot 7. The two brackets 16 support the bottom of the electrical equipment. The staff can fix the electrical equipment in the bolt mounting holes of the equipment slot 7 by bolts, and install multiple electrical equipment in other equipment slots 7 in turn. Subsequently, the staff pushes the mounting plate 3 to swing, so that the mounting plate 3 is received in the cabinet 1. When the mounting plate 3 contacts the inclined surfaces of the two buckle plates 13, the mounting plate 3 pushes the buckle plate 13 to rotate along the outer side of the sleeve rod 12 and contacts with the limit spring plate 34. When the mounting plate 3 is away from the inclined surface of the pinch plate 13, the rebound force of the coil spring 14 is used to make the pinch plate 13 stuck on the outer side of the mounting plate 3, so that the mounting plate 3 is fixed on the inner side of the cabinet 1, and the installation of the electrical equipment is realized. At the same time, the mounting plate 3 drives the transmission rod 20 to swing synchronously, so that the second bevel gear 23 on the transmission rod 20 moves along the second bevel gear 23 on the positioning frame 22, so that the second bevel gear 23 drives the transmission rod 20 to rotate, and the transmission rod 20 drives the corresponding rotating rod 17 to rotate through the first bevel gear 21, and the rotating rod 17 drives the remaining rotating rods 17 to rotate synchronously through the synchronous belt, and the rotating rod 17 drives the moving block 18 to move along the outer side of the bracket 16 through the outer thread on its outer side, so that the moving block 18 drives the rubber block 35 on the abutment plate 19 to contact the outer side of the electrical equipment, and the elasticity of the second tension spring 37 is used to make the rubber block 35 elastically clamp the electrical equipment to prevent the electrical equipment from loosening, thereby improving the firmness of the installation of the electrical equipment, thereby achieving the effect of facilitating installation and installation protection; When the electrical equipment needs to be disassembled for maintenance, the staff opens the cabinet door 2 and swings the mounting plate 3 to the outside of the cabinet body 1. At this time, the side of the mounting plate 3 away from the electrical equipment is on the outside of the cabinet door 2, which is convenient for the staff to disassemble the bolts of the electrical equipment through the back of the mounting plate 3. In addition, the two brackets 16 can provide support for the bottom of the electrical equipment to prevent the electrical equipment from falling during disassembly, thereby improving the convenience of disassembly and maintenance of the electrical equipment. At the same time, the positioning block 8 of the mounting plate 3 drives the driven rod 29 to rotate synchronously, so that the driven rod 29 drives the driven gear 30 to rotate, and the driven gear 30 drives the gear 30 to rotate through the rack 31. The plate 24 moves along the bottom of the two cabinets 1, so that the baffle 24 drives the sealing plate 25 to move synchronously, and the inclined surface on the left side of the sealing plate 25 moves along the inclined surface of the first cleaning hole of the cabinet 1. The sealing plate 25 can move downward along the sliding cavity of the baffle 24 and push the support rod 26 to move. The support rod 26 stretches the first tension spring 28 through the limit plate 27, so that the second cleaning hole on the baffle 24 is aligned with the first cleaning hole of the cabinet 1. The staff can discharge the dust inside the cabinet 1 from the first cleaning hole and the second cleaning hole to facilitate the cleaning of the dust in the cabinet 1, thereby achieving the effect of facilitating disassembly, maintenance and dust cleaning.
