A door panel assembly 200 is provided on the front of the outer shell 101. A cabinet door locking assembly 300 is provided on the back of the door panel assembly 200. The outer shell 101 is rotatably connected to the door panel assembly 200 through a shaft center 102. An electrical protection mechanism is provided inside the outer shell 101. A heat dissipation mechanism penetrates through the top of the outer shell 101. Ventilation mechanisms are provided on both sides of the lower end of the outer shell 101. Support mechanisms are also provided on both sides of the lower end of the outer shell 101. The cabinet door is locked tightly by the cabinet door locking assembly 300 to prevent the cabinet door 201 from being accidentally opened. The internal electrical components are separated by the electrical protection structure to prevent accidents caused by mutual influence of the electrical components. The heat dissipation mechanism dissipates heat from the inside of the cabinet body 100 to ensure the normal operation of the electrical components. The ventilation mechanism can ensure the air circulation inside the cabinet body 100 and improve the heat dissipation effect. The support mechanism can improve the stability of the device and prevent the device from shaking and damaging the components inside the cabinet.

[0033] In one embodiment, as Figure 3 shown, the electrical protection mechanism includes partition boards 103, perforations 104, electrical components 105, and connecting wires 106. A plurality of partition boards 103 are provided inside the outer shell 101. Perforations 104 penetrate through the partition boards 103. An electrical component 105 is provided between two adjacent partition boards 103. The electrical components 105 are connected to each other through connecting wires 106. The partition boards 103 are used to isolate adjacent electrical components 105. By providing perforations 104 on the partition boards 103, entanglement between the connecting wires 106 can be avoided, ensuring the normal operation of the electrical components 105.

[0034] In one embodiment, as Figure 4 shown, the heat dissipation mechanism includes a protection frame 107, fans 108, and heat dissipation openings 109. Two fans 108 are provided at the bottom of the protection frame 107. The fans 108 penetrate through the top of the outer shell 101. A plurality of heat dissipation openings 109 are provided at the top of the protection frame 107. The inside of the cabinet body 100 is dissipated heat by the fans 108 to prevent accidents caused by overheating of the electrical components 105.

[0035] In one embodiment, as Figure 5 shown, the ventilation mechanism includes ventilation openings 110 and shielding plates 111. Three groups of ventilation openings 110 penetrate through both sides of the lower end of the outer shell 101.

The lock rod mechanism includes a locking rod 303, a fixing plate 304, a return spring 305 and a limiting block 306. The upper end of the locking rod 303 is rotatably connected to the second rotating rod 302. The lower end of the locking rod 303 is provided with the limiting block 306. A return spring 305 is disposed around the lower end of the locking rod 303 at a position above the limiting block 306. A fixing plate 304 is provided on the surface of the cabinet door 201 at a position above the return spring 305. The locking rod 303 penetrates through the fixing plate 304, and the locking rod 303 is slidably connected to the fixing plate 304. A groove 117 matching the locking rod 303 is provided on the inner surface of the outer shell 101 corresponding to the position of the locking rod 303. During use, turn the handle 202 to move the upper and lower locking rods 303 towards the first rotating rod 301. After closing the door panel assembly 200, release the handle 202. Under the action of the return spring 305, the locking rod 303 enters the groove 117 to complete the locking of the cabinet door.

[0039] The above embodiment discloses a PLC control cabinet with a protection function. By providing through holes 104 in the cabinet, while separating the electrical components 105, the connecting wires 106 connecting the electrical components 105 pass through different through holes 104 in sequence, preventing the connecting wires 106 from winding around each other and affecting the normal operation of the electrical components 105. The fan 108 is used to dissipate heat from the electronic components in the cabinet, maintaining a dry and cool environment in the cabinet. The dust shield 111 provided above the ventilation opening 110 can reduce the dust entering the cabinet. The shock absorber 115 can prevent the components in the cabinet from being damaged due to the shaking of the device. When closing the cabinet door 201, insert the locking rod 303 into the groove 117 to lock the cabinet door 201, preventing the cabinet door 201 from being accidentally opened and affecting the normal operation of the components in the cabinet.
