[0030] like Figure 1-10 As shown in the figure, the power distribution cabinet is described in detail:

[0031] A power distribution cabinet comprises a back plate 101 with extension plates 102 at both left and right ends, end plates 106 at both upper and lower ends of the back plate 101, middle tubes 104 at the front ends of the two extension plates 102, end tubes 203 coaxially rotating at the upper and lower ends of the middle tube 104, and the two coaxial end tubes 203 and the middle tube 104 penetrate the side shaft 103, side plates 201 are fixed on the two coaxial end tubes 203, front plates 202 are vertically fixed on the front ends of the two side plates 201, limiting columns 107 are vertically fixed at the four corners of the back plate 101, and a mounting frame 301 for mounting electrical components is slid through the four limiting columns 107, and L-shaped plates 204 are fixed on the four end tubes 203. When the front plate 202 is opened, the L-shaped plate 204 will rotate with the front plate 202 around the side shaft 103 to push the mounting frame 301 forward.

[0032] When the power distribution cabinet is closed, the two front panels 202 are aligned at the front end and press against the front end of the limit column 107. At the same time, the two side panels 201 are arranged in parallel with the two extension panels 102 to form a closure on the side. Thus, the back panel 101, the two extension panels 102, the two side panels 201, the two front panels 202 and the two end panels 106 form a cabinet body to protect the electrical components on the installation frame 301.

[0033] When opening, both front panels 202 are provided with pull plates. By pulling the two pull plates forward, the two front panels 202 drive the two side panels 201 to rotate with the two side shafts 103 as axes, so that the front end of the cabinet is opened while the front parts of both sides of the cabinet are also opened, thereby expanding the opening space of the cabinet. At the same time, the L-shaped plate 204 is driven by the side panel 201 to rotate with the side shaft 103 as axis, and the installation frame 301 is pushed forward on the four limit columns 107, thereby forming the installation frame 301 driving the electrical components to move toward the front end opening, so that the electrical components are in the wide space at the front end opening of the cabinet, which is convenient for maintenance personnel to operate and improves the maintenance and detection efficiency.

[0034] Further:

[0035] The front ends of the limiting columns 107 are all provided with springs 302 , and the four springs 302 are all pressed backwards against the mounting frame 301 .

[0036] The installation frame 301 is pushed backward by the elastic force of the spring 302. When the pull plate is released, the installation frame 301 will automatically move backward and push the side plate 201 to rotate through the L-shaped plate 204, thereby realizing automatic closing of the cabinet.

[0037] like Figure 5-7 As shown:

[0038] A C-shaped plate 303 is fixedly extended backwards on the rear end surface of the installation frame 301 , and the four L-shaped plates 204 are slidably connected to the two C-shaped plates 303 respectively.

[0039] By setting the C-shaped plate 303, when the L-shaped plate 204 rotates, it slides on the C-shaped plate 303 and pushes the installation frame 301 to move forward, thereby preventing the L-shaped plate 204 from contacting the electrical components on the installation frame 301 and causing damage to the electrical components;

[0040] Moreover, through the setting of the C-shaped plate 303, when the cabinet is closed, the installation frame 301 is positioned by pressing the L-shaped plate 204 with the rear end of the C-shaped plate 303, so that a reserved space is formed between the installation frame 301 and the back plate 101 to place the cables without worrying about being scratched by the L-shaped plate 204.

[0041] Further:

[0042] Both ends of the two C-shaped plates 303 are provided with limiting edges 305 , and the four L-shaped plates 204 are provided with through slots 205 .

[0043] By setting the limiting edge 305, when the L-shaped plate 204 slides to the end of the rear end of the C-shaped plate 303, it is blocked by the limiting edge 305, thereby stopping the sliding, preventing the L-shaped plate 204 from sliding over the C-shaped plate 303 and becoming inconvenient to rotate. At the same time, by setting the through slot 205, when the C-shaped plate 303 is pressed against the L-shaped plate 204, the limiting edge 305 is inserted into the through slot 205.

[0044] like Figure 7 ,9-10 as shown:

[0045] It also includes a crossbeam plate 501, and a plurality of mounting holes 304 are symmetrically arranged on the left and right side plates of the mounting frame 301. Both ends of the crossbeam plate 501 are provided with sleeves 502, and both sleeves 502 are provided with mounting shafts 503. The two mounting shafts 503 are respectively inserted into two symmetrical mounting holes 304.

[0046] A notch is provided at the edge of the mounting hole 304 , and a clamping plate 504 corresponding to the notch is provided at the rear end of the mounting shaft 503 .

[0047] The crossbeam plate 501 is provided for installing electrical components, so that the number of crossbeam plates 501 can be increased or decreased according to actual needs. When installing or removing the crossbeam plate 501, the installation shaft 503 is rotated so that the installation shaft 503 drives the clamping plate 504 to rotate to a position corresponding to the notch on the installation hole 304, and the installation shaft 503 is installed or removed from the installation hole 304 to achieve installation or removal. After the installation is completed, the installation shaft 503 is rotated again to misalign the clamping plate 504 with the notch to achieve installation locking of the crossbeam plate 501.

[0048] like Figure 4-6 ,8 as shown:

[0049] A locking frame 105 is provided on the end plate 106 at the upper end, and two sliders 401 slide in the locking frame 105. Locking plates 402 are rotated at the front ends of the two sliders 401, and the two locking plates 402 automatically fall into the through holes in the locking frame 105 away from the ends of the sliders 401. An adjusting bidirectional screw 403 is rotated horizontally through the locking frame 105, and the two sliders 401 are respectively threadedly connected to the two ends of the adjusting bidirectional screw 403, and L-shaped locking plates 206 are fixed to the upper ends of the two front plates 202.

[0050] By rotating and adjusting the bidirectional screw rod 403, the two sliders 401 can be driven to move closer or farther away at the same time. When the two sliders 401 are close to each other, the locking plates 402 on the two sliders 401 away from the sliders 401 will be affected by their own gravity and automatically fall into the through hole in the locking frame 105 until they enter the cabinet and are inserted into the gap between the L-shaped locking plate 206 and the front plate 202 to lock the front plate 202. When the two sliders 401 are away from each other, the locking plates 402 on the two sliders 401 away from the sliders 401 will be affected by the edge of the through hole in the locking frame 105 and gradually slide into the locking frame 105 to release the lock on the front plate 202.

[0051] At the same time, special wrench twisting grooves can be provided at both ends of the adjusting bidirectional screw 403 to prevent non-professionals from opening the cabinet.

[0052] Further:

[0053] A plurality of hoses Ⅰ 108 communicating with the outside are connected between the extension plate 102 and the back plate 101;

[0054] When wind blows from the rear end or the left and right ends, the wind will enter the hose I 108 through the holes on the back plate 101 or the extension plate 102, thereby dissipating heat inside the cabinet and improving the heat dissipation efficiency of the cabinet.

[0055] Similarly, a plurality of hoses II 207 communicating with the outside are connected between the front plate 202 and the corresponding side plates 201 .

[0056] When wind blows from the front or left and right ends, the wind will enter the hose II 207 through the holes on the front plate 202 or the side plate 201, thereby dissipating heat inside the cabinet and improving the heat dissipation efficiency of the cabinet.

[0057] Furthermore, since hose I 108 and hose II 207 are both made of soft materials, they will automatically fall down and can also be placed on electrical components to better dissipate heat from the electrical components.

[0058] Further:

[0059] By fixing a support frame 109 at the end plate 106 at the lower end corresponding to the extension plate 102, the main load-bearing portion of the end plate 106 is located at the corresponding extension plate 102, thereby preventing the end plate 106 at the front end of the extension plate 102 from being deformed due to force and affecting the cabinet switch.
