[0009] Preferably, a pull bracket is provided on the front side of the lower end of the back plate, and the pull bracket is connected to the back plate. The pull bracket is used to pull the back plate to move back and forth.

[0010] Preferably, a fan is installed inside the upper part of the cabinet, and a dust cover is installed above the fan and connected to the cabinet. The fan is used to generate airflow to dissipate heat inside the cabinet.

[0011] Preferably, air inlet slots are provided on both sides of the exterior of the cabinet, and the air inlet slots are integrally formed with the cabinet, and the air inlet slots are used for air entry.

[0012] Preferably, the air inlet slot is provided with a dustproof net inside, and a rainproof shell is provided outside the dustproof net. The dustproof net is used to intercept dust.

[0013] Preferably, the upper end of the cabinet is provided with a top cover, and the top cover is connected to the cabinet through a bracket. The top cover is used to protect the cabinet from rain when it is used outdoors.

[0014] Preferably, a base block is provided at each of the four corners of the lower end of the cabinet, and an adjusting screw is installed at the lower end of the base block through a threaded connection. An adjusting base is provided at the lower end of the adjusting screw, and the adjusting screw makes it easy to raise and lower the adjusting base.

[0015] Compared with the prior art, the present invention provides a power distribution switch cabinet with the following advantages:

[0016] This invention solves the problems mentioned in the background art by setting a track rod structure on the back plate and using a limiting block structure to lock and unlock the back plate, so that the back plate can move back and forth outside the track rod, thereby facilitating the disassembly and assembly of equipment outside the back plate.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] This utility model provides a technical solution, a power distribution switchgear; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 ,include:

[0023] Cabinet 1, with a back panel 6 inside the cabinet 1. Each of the four corners of the back panel 6 is equipped with a track rod 5, and the track rod 5 is connected to the cabinet 1. The back panel 6 is slidably connected to the track rod 5.

[0024] A fixing block 8 is provided on one side of the upper end of the back plate 6 and is connected to the cabinet 1. A return spring 9 is provided on one side of the upper end of the back plate 6. A limit block 11 is provided at the lower end of the return spring 9. An insertion hole adapted to the limit block 11 is provided at the upper end of the inside of the fixing block 8. A fixing plate 10 is provided on the front side of the upper end of the back plate 6 and the limit block 11 is slidably connected to the fixing plate 10.

[0025] Side doors 18 are located on both sides inside the cabinet 1 and are rotatably connected to the cabinet 1. A door panel 19 is rotatably installed on the front end of the cabinet 1.

[0026] Please see Figure 3 A pull bracket 7 is provided on the front side of the lower end of the back plate 6, and the pull bracket 7 is connected to the back plate 6. The pull bracket 7 is used to pull the back plate 6 to move back and forth.

[0027] Please see Figure 1 and Figure 2 A fan 3 is installed inside the upper part of the cabinet 1. A dust cover 4 is installed on the upper part of the fan 3 and is connected to the cabinet 1. The fan 3 is used to generate airflow to dissipate heat inside the cabinet 1.

[0028] Please see Figure 1 and Figure 2 Air inlet slots 12 are provided on both sides of the exterior of the cabinet 1, and the air inlet slots 12 are integrally formed with the cabinet 1. The air inlet slots 12 are used for air entry.

[0029] Please see Figure 1 and Figure 2 The air inlet slot 12 is equipped with a dustproof net 13 inside, and a rainproof shell 14 is provided outside the dustproof net 13. The dustproof net 13 is used to intercept dust.

[0030] Please see Figure 1 and Figure 2 The cabinet 1 is provided with a top cover 2 at the top, and the top cover 2 is connected to the cabinet 1 by a bracket. The top cover 2 is used to protect the cabinet 1 from rain when it is used outdoors.

[0031] Please see Figure 1 and Figure 2 Each of the four corners of the lower end of the cabinet 1 is provided with a base block 15. The lower end of the base block 15 is fitted with an adjusting screw 16 through a threaded connection. The lower end of the adjusting screw 16 is provided with an adjusting base plate 17. The adjusting screw 16 makes it easy to raise and lower the adjusting base plate 17.

[0032] This solution: When it is necessary to disassemble or assemble the equipment on the upper part of the back panel 6, pull the limiting block 11 upward to disengage it from the fixing block 8, thereby removing the fixation of the back panel 6. Then, pull the back panel 6 forward by the pull bracket 7. When the back panel 6 moves to the front end of the cabinet 1, open the side door 18 to disassemble or assemble the equipment at both ends of the back panel 6. When the cabinet 1 is in use, start the fan 3 to generate an upward airflow, which allows the air outside the cabinet 1 to enter the cabinet 1 through the dustproof net 13 and then be discharged from the top of the cabinet 1, thereby dissipating heat from the inside of the cabinet 1.
