[0036] like Figures 4-5 The installation mechanism 2 includes a base plate 21, which is used to connect various components. A cover plate 22 is fixedly connected to the front of the base plate 21, which is used to cooperate with the base plate 21. A screw 23 is rotatably connected through the middle of the base plate 21, which is used to cooperate with the sliding of the slider 24. A slider 24 is threadedly connected through the outside of the screw 23, which is used to cooperate with the adjustment of the position of the support rod 25. The left and right sides of the front side of the slider 24 are rotatably connected to the support rod 25. The upper end of the support rod 25 is connected to the slider 24. The lower end of the support rod 25 is movably connected to the connecting plate 26, which is used to cooperate with the clamping plate 27 to move. The two connecting plates 26 are fixedly connected to the clamping plate 27 on the side away from each other, which is used to cooperate with the installation of the cabinet 1. The two clamping plates 27 are fixedly connected to the side close to each other, which is used to cooperate with the fixing sleeve 11 to cooperate with the fixing of the cabinet 1.

[0037] Furthermore, mounting plates 211 are fixedly connected to the upper and lower sides and left and right sides of the outer wall of the base plate 21, which can provide bolt fixation to cooperate with the fixing of the mounting mechanism 2. A sliding groove 212 is opened in the middle of the front side of the base plate 21, which is used to cooperate with the movement of the slider 24. The slider 24 is slidably connected to the sliding groove 212. A sliding opening 214 is opened in the lower part of the sliding groove 212, which is used to cooperate with the connection and movement of the connecting plate 26. The connecting plate 26 is slidably connected to the sliding opening 214. The middle of the sliding groove 212 and the sliding opening 214 are connected together. A limiting groove 213 is provided to cooperate with the connection of the limiting block 241. An auxiliary groove 221 is provided in the middle of the rear side of the cover plate 22 to cooperate with the movement and use of the support rod 25. An auxiliary opening 222 is provided at the lower part of the auxiliary groove 221 to cooperate with the use of the connecting plate 26. The limiting block 241 is fixedly connected to the rear side of the slider 24 to cooperate with the connection of the slider 24 and can limit the movement direction of the slider 24 to a certain extent. The limiting block 241 and the limiting groove 213 are slidably connected.

[0038] Please see Figures 6-7 The left and right sides of the cabinet 1 are fixedly connected with fixing sleeves 11, which are used to fix the fixing block 28. The fixing block 28 is movably connected to the fixing sleeve 11. The lower left and right sides of the cabinet 1 are provided with heat dissipation vents 12, which are used for heat dissipation of the grid-connected cabinet. The front and rear parts of the heat dissipation vents 12 are provided with positioning grooves 13, which are used to cooperate with the installation of dustproof plate 4.

[0039] Furthermore, the dustproof panel 4 has grooves 41 on both the upper and lower parts of its side near the cabinet 1, which are used to pull the dustproof panel 4. The grooves are located between the two mounting blocks 33. Positioning strips 42 are fixedly connected to the front and rear parts of the side of the dustproof panel 4 near the cabinet 1, which are used to position the dustproof panel 4 during installation. The positioning strips 42 are movably connected to the positioning grooves 13. The limiting component 3 includes a housing 31, which is used to connect the various components. The housing 31 is fixedly connected to the cabinet 1, and a connecting rod is slidably connected inside the housing 31. When the dustproof plate 4 is installed, a certain distance is left between the upper and lower sides of the connecting strip 32 and the connecting strip 32, so that the workers can insert their hands or tools into the pull groove 41. The front and rear parts of the connecting strip 32 near the dustproof plate 4 are fixedly connected to the front and rear parts. The side of the mounting block 33 near the dustproof plate 4 is set as a semi-cylindrical shape to facilitate the disassembly and assembly of the dustproof plate 4. The connecting strip 32 and the outer shell 31 are fixedly connected to a spring 34, and there are multiple springs, which are used to cooperate with the movement and reset of the connecting strip 32.

[0040] Working principle: When using the cabinet 1, firstly, fix multiple mounting plates 211 to the wall or mounting bracket with bolts. Then, place the cabinet 1 in front of the cover plate 22. Then, rotate the screw 23 with a tool to make it drive the slider 24 to slide. Since one end of the support rod 25 is connected to the slider 24 and the other end is movably connected to the connecting plate 26, when the slider 24 moves, it will drive the two support rods 25 to move. The connecting plate 26 connected to the support rod 25 will be driven to slide in the sliding opening 214. The two connecting plates 26 will drive the clamping plate 27 fixed to them to move closer to each other, so that the fixing block 28 is inserted into the fixing sleeve 11, thereby fixing the cabinet 1 to the mounting mechanism 2.

[0041] When the dust cover 4 needs to be cleaned or replaced, the worker first inserts their fingers or tools into the pull grooves 41 on the upper and lower sides of the dust cover 4, and then pulls the dust cover 4 away from the cabinet 1. At this time, the upper and lower sides of the dust cover 4 will push the mounting block 33, and the mounting block 33 will drive the connecting strip 32 to move into the outer shell 31 and squeeze the spring 34 until the dust cover 4 drives the positioning strip 42 out of the positioning groove 13 and the dust cover 4 is completely separated from the cabinet 1. During installation, align the positioning strip 42 with the positioning groove 13, and then push the dust cover 4 towards the cabinet 1. At this time, the dust cover 4 will push the mounting block 33, and the mounting block 33 will push the connecting strip 32 again. When the positioning strip 42 is fully inserted into the positioning groove 13, the mounting block 33 will lose the force applied by the dust cover 4, and the spring 34 will return to its original position, thereby fixing the dust cover 4 in place.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
