[0012] Beneficial effects of the present invention:

[0013] (1) The ring network distribution cabinet of the present invention is easy to inspect and maintain. The protective structure can effectively prevent pedestrians or lighter vehicles from hitting and bumping the distribution cabinet and causing damage to the internal electrical components. It can also effectively prevent rainwater and debris from entering the distribution cabinet in rainy and windy weather and causing certain damage to the electrical components. The heat dissipation structure can effectively dissipate the heat in the outdoor distribution cabinet quickly, so as to prevent the electrical components from being damaged by overheating. That is: when the operator rotates the first rocker fixedly connected to one end of the distribution cabinet by a bearing, the first rocker will rotate, and the rotation of the first rocker will drive the first gear ring fixed on the outer wall, thereby driving the first rack meshed with it, so that the first rack slides on the first slide groove on the second protective plate, thereby driving the rotating block meshed with it at the other end, so that the rotating block slides out of the fixed groove inside the second protective plate, so that the operator can open the first protective plate and the second protective plate to inspect and maintain the interior of the distribution cabinet. The power distribution cabinet can be opened very conveniently by slightly turning the first rocker, and the first protective plate and the second protective plate can also well protect the electrical components inside the power distribution cabinet, preventing pedestrians or some lighter vehicles from colliding with it and causing damage to the electrical components. When the power distribution cabinet is placed outdoors for a long time and exposed to sunlight, the operator can rotate the second rocker fixedly connected to the power distribution cabinet through a bearing, which can drive the first sprocket fixedly connected to the other end of the second rocker, so that the first sprocket transmits force to the second sprocket through the chain, thereby driving the first fixed shaft fixedly connected to the second sprocket, and then the first bevel gear at the other end of the first fixed shaft rotates, so that the first bevel gear drives the second bevel gear meshed with it, thereby driving the fan fixedly connected to one end of the second bevel gear, causing the fan to rotate, so that the operator can make the fan rotate faster by using the different sizes of the first sprocket and the second sprocket, so that the hot air inside the power distribution cabinet can be blown away quickly, preventing the electrical components from being damaged by overheating.

[0014] (2) The ring network distribution cabinet of the present invention is easy to inspect and maintain. The wiring structure can store and protect the wiring connected to the electrical components, so that the operator can easily retract and release the wiring when repairing the electrical components. The fixing structure can fix the electrical components inside the distribution cabinet, making the operation convenient during inspection or installation. That is, the operator can take out the wiring connected to the electrical components from the wiring outlet slot opened at one end of the distribution cabinet, and then put the wiring into the wiring box through the wiring inlet slot opened at one end of the wiring box, and then take it out from between the fixed tube and the wiring box. The operator can turn the first knob so that the first knob drives the third bevel gear fixedly connected to the other end of the first screw, so that the third bevel gear drives the fourth bevel gear meshed with it, and the fourth bevel gear drives the fourth bevel gear threadedly connected to it. The internal thread block allows the internal thread block to rise or fall, which in turn allows the fixed tube to rise or fall, so that the wires can be well resisted, so that when the other end of the wire is pulled, the wire will also return when it returns to its position, so that the wires can be well stored and released, so that during maintenance, the operator can well dismantle and repair the machine, and then the operator places the electric meter or other electrical components between the two mounting frames, and then the operator turns the handle to drive the second screw fixed to it, so that the second screw drives the mounting frame threadedly connected to it, because the two ends of the second screw are reverse thread structures, so it will drive the two mounting frames to move toward the auxiliary frame, so that the rubber plate installed at one end of the auxiliary frame fixed on the mounting frame will clamp the device, so that it can well clamp the electrical components while also being well removed for replacement and repair.

[0015] (3) The present invention describes a ring network distribution cabinet that is easy to inspect and maintain. Through the adjustment structure, the operator can well flip the electrical components in a small range so that the electrical components can be well installed and removed between the electrical components and the circuit. Through the rotation structure, the electrical components can be well adjusted in a large range of angles, thereby facilitating the repair and installation of the electrical components and making it more convenient for the operator to inspect and maintain. That is, the operator can drive the third screw by turning the second knob to make the second rack slide, thereby driving the second gear ring engaged with it to make the slide tube rotate, and the slide tube drives the mounting frame to rotate, so that the operator can well flip the electrical components by turning the second knob for better repair. When the operator needs to pull out the electrical component, the operator first pulls the pin so that the pin contacts the fixed arm in a conflicting state, so that the fixed arm and the fixed frame rotate, and the first tooth block contacts the second tooth block, so that the fixed arm can be well limited, so that after the fixed arm is pulled, there is also a certain fixing effect between the fixed arm and the fixed frame, making it more convenient for the operator to repair.

The operator can turn the first knob 44 so that the first knob 44 drives the third bevel gear 45 fixedly connected to the other end of the first screw 46, so that the third bevel gear 45 drives the third bevel gear 45 connected to it. The meshed fourth bevel gear 47 drives the internal thread block 48 threadedly connected thereto, so that the internal thread block 48 rises or falls, causing the fixed tube 49 to rise or fall, so that the wires can be well resisted, so that when the other end of the wire is pulled, the wire will also return when it returns to its original position, so that the wires can be well stored and released, so that during maintenance, the operator can well dismantle and repair the machine, and then the operator places the electric meter or other electrical components between the two mounting brackets 54, and then the operator turns the handle 57 to drive the second screw 56 fixedly connected thereto, so that the second screw 56 drives the mounting bracket 54 threadedly connected thereto, because the two ends of the second screw 56 are mutually reverse threaded structures,Therefore, the two mounting frames 54 will be driven to move toward the auxiliary frame 55, so that the rubber plate 59 installed at one end of the auxiliary frame 55 fixed on the mounting frame 54 will clamp the device, so that the electrical components can be well clamped and can also be well removed for replacement and repair. In addition, the operator turns the second knob 61 to drive the third screw 62, so that the second rack 63 slides, thereby driving the second gear ring 65 engaged therewith to rotate the slide tube 52, so that the slide tube 56 drives the mounting frame 54 to rotate, so that the operator can rotate the third screw 62 to rotate the second rack 63. The second turn button 61 can be used to flip the electrical component for better repair. When the operator needs to pull out the electrical component, the operator first pulls the latch 76, so that the latch 76 contacts the interference state of the fixed arm 51, causing the fixed arm 51 and the fixing frame 71 to rotate. The first tooth block 73 will interfere with the second tooth block 74, thereby effectively limiting the fixed arm 51. After pulling the fixed arm 51, the fixed arm 51 and the fixing frame 71 also have a certain fixing effect, making it more convenient for the operator to repair.
