[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] like Figures 1 to 5 As shown, the utility model provides a power distribution cabinet for computer room construction, including:

[0026] U-shaped plate 1, the inner surface of the U-shaped plate 1 is movably connected with a movable plate 2, the number of movable plates 2 is two, the inner sides of the two movable plates 2 are fixedly connected with springs 3, the other end of the spring 3 is fixedly connected to the inner wall of the U-shaped plate 1, and the middle part of the back of the U-shaped plate 1 is fixedly connected with a rectangular box 4;

[0027] An expansion mechanism, the expansion mechanism is arranged inside the rectangular box 4;

[0028] Among them, the expansion mechanism includes a driving motor 5, which is fixedly installed inside the rectangular box 4. The other end of the output shaft of the driving motor 5 is fixedly sleeved with a rotating shaft 6. The outer surface of the rotating shaft 6 is fixedly sleeved with a protrusion 7. The outer surface of the protrusion 7 is movably connected to the inner surface of the U-shaped plate 1. The protrusion 7 rotates and squeezes to push the two movable plates 2 to move away from each other.

[0029] When the driving motor 5 is running, the rotating shaft 6 will drive the protrusion 7 to rotate. When the protrusion 7 rotates until the two movable plates 2 are in contact, it will squeeze and push the two movable plates 2 to move away from each other, thereby achieving the purpose of expanding the volume of the distribution cabinet.

[0030] The inner sides of the two movable plates 2 are both provided with heat dissipation holes 8 , and the heat dissipation holes 8 are rectangular in appearance.

[0031] The design of the heat dissipation holes 8 serves to dissipate heat from the electronic components inside the U-shaped plate 1 .

[0032] Among them, dustproof plates 9 located outside the heat dissipation holes 8 are movably installed inside the two movable plates 2, and the number of dustproof plates 9 is two. The tops of the outer sides of the two dustproof plates 9 are fixedly connected with first handles 15.

[0033] The dustproof plate 9 can be disassembled by pulling the first handle 15 outward.

[0034] Among them, the interior of the two movable plates 2 is provided with a slide groove 10 located above the dustproof plate 9, and the outer sides of the two movable plates 2 are fixedly connected with a pneumatic cylinder 11 located above the dustproof plate 9. The front end of the pneumatic cylinder 11 is fixedly connected with a round rod 12, and the outer surface of the round rod 12 is movably connected to the inner surface of the slide groove 10. The inner side of the round rod 12 passes through the slide groove 10 and extends to the interior of the slide groove 10 and is movably connected with a rotating block 13. The internal movably sleeve of the rotating block 13 is a round shaft 14, which is fixedly installed in the interior of the slide groove 10. The rotating block 13 rotates to release the fixing effect on the dustproof plate 9.

[0035] When the pneumatic cylinder 11 is running, it will pull the round rod 12 to move backward, thereby causing the rotating block 13 to rotate around the round shaft 14. When the rotating block 13 rotates to the top of the dustproof plate 9, the fixing effect of the dustproof plate 9 will be released. At this time, the first handle 15 is pulled outward to achieve the removal of the dustproof plate 9.

[0036] The front sides of the two movable panels 2 are both hinged with rectangular doors 16 , and the number of the rectangular doors 16 is two. The back sides of the two rectangular doors 16 are both movably connected to the front side of the U-shaped panel 1 .

[0037] The design of the rectangular door 16 serves to seal and protect the U-shaped plate 1 .

[0038] The front sides of the two rectangular doors 16 are both fixedly connected with second handles 17 , and the outer surface of the second handles 17 is rough.

[0039] The rough design of the outer surface of the second handle 17 makes it easier for the operator to hold the second handle 17 better.

[0040] There are four springs 3 , the four springs 3 have the same size, and the four springs 3 are symmetrical with respect to the center of the U-shaped plate 1 .

[0041] The design of four springs 3 has a better reset effect on the two movable plates 2.

[0042] The working principle and use process of this utility model:

[0043] When repairing the electronic components on both sides of the U-shaped plate 1, the operator first pulls the rectangular door 16 to open the second handle 17, and then starts the drive motor 5, which will cause the rotating shaft 6 to drive the protrusion 7 to rotate. When the protrusion 7 rotates to contact the two movable plates 2, it will squeeze and push the two movable plates 2 to move toward each other, thereby expanding the volume of the distribution cabinet, thereby facilitating the operator to repair the electronic components on both sides of the U-shaped plate 1. When the repair is completed, the drive motor 5 is started again to drive the protrusion 7 to reset. At this time, the two movable plates 2 are driven to move toward each other and reset under the elastic recovery action of the spring 3.

[0044] When the dustproof plate 9 is replaced, the pneumatic cylinder 11 is started, which will pull the round rod 12 to move backward, thereby causing the rotating block 13 and the round shaft 14 to rotate as the axis. When the rotating block 13 rotates to the top of the dustproof plate 9, the fixing effect of the dustproof plate 9 will be released. At this time, the dustproof plate 9 can be disassembled by pulling the first handle 15 outward, thereby facilitating the disassembly and replacement of the dustproof plate 9.
