The slides 2221 correspond to the slide rails 12, and a bell mouth 2222 is provided at one end of the slide 2221 and a "C"-shaped slide groove 2223 is opened on the inner side. A permanent magnetic lock block 2224 is inserted into the outer side of one group of the slides 2221. The permanent magnetic lock block 2224 corresponds to the electromagnetic switch 14. When the electromagnetic switch 14 is started, the permanent magnetic lock block 2224 is attracted by the strong magnetism generated by the electromagnet 1411 and can be clamped between the locking blocks 1412. The cooperation of the "C"-shaped slide groove 2223 and the slide rail 12 improves the sliding stability of the chassis drawer 22; the spring sheet design of the movable block 213 ensures the reliability of the connection and the convenience of operation.

[0048] It is particularly disclosed that a group of inner sides of the side vertical plate 222 located on the rear side are provided with a second card strip 2225 and an air outlet fan 2226. The second card strip 2225 corresponds to the fixed card block 214. The air outlet fan 2226 and the air intake fan 2212 are connected to the processor. The air outlet fan 2226 and the air intake fan 2212 cooperate to dissipate heat for the industrial control chassis.

[0049] It should be particularly emphasized that a temperature sensor 2227 is provided on the inner side of the side panel 222, and the temperature sensor 2227 is connected to the processor. The temperature sensor 2227 is located on the inner side of the exhaust fan 2226. The temperature sensor 2227 is used to monitor the temperature inside the chassis in real time, and provide a basis for heat dissipation control. The temperature sensor 2227 monitors the temperature inside the chassis in real time, and the processor dynamically adjusts the power of the intake fan 2212 and the exhaust fan 2226 according to the temperature changes, thereby reducing energy consumption while ensuring the heat dissipation effect.

[0050] Example 2:

[0051] According to the attached Figure 1-10 As shown, it includes a fixing sleeve 1, a box body 2 and a processor. The box body 2 is located inside the fixing sleeve 1. The fixing sleeve 1 is provided with a sleeve shell 11. A sensing block 13 and an electromagnetic switch 14 are provided on one side of the sleeve shell 11. The box body 2 includes a chassis cover 21 and a chassis drawer 22. A card slot 212 is provided on the chassis cover 21, and a movable card block 213 is inserted into the inner side of the card slot 212; the chassis drawer 22 is located below the chassis cover 21, and a proximity switch 2214 and a permanent magnetic lock block 2224 corresponding to the sensing block 13 and the electromagnetic switch 14 are provided on the chassis drawer 22; the proximity switch 2214 and the electromagnetic switch 14 are both connected to the processor. The proximity switch 2214 is used to detect whether the chassis drawer 22 is open, and the electromagnetic switch 14 is used to lock the chassis drawer 22. When the power is off, the electromagnetic switch 14 will remain locked, so that the chassis drawer 22 cannot be opened, so as to protect the safety of the equipment.

[0052] It should be particularly emphasized that the processor controls the industrial computer chassis, and the temperature sensor 2227 is used to detect the ambient temperature inside the chassis. The temperature sensor 2227 controls the output power of the intake fan 2212 and the exhaust fan 2226 according to the ambient temperature inside the chassis. The processor can control the opening of the electromagnetic switch 14 while detecting the proximity switch 2214. When the electromagnetic switch 14 is normally turned on under the control of the processor, the box body 2 can be pulled out normally when the proximity switch 2214 is turned on. When the electromagnetic switch 14 is abnormally turned on, an alarm is issued to the system when the box body 2 is pulled out.

[0053] The specific working principle is that the processor sends instructions to control the electromagnetic switch 14 to turn on, and the electromagnet 1411 generates a magnetic field to attract the permanent magnetic lock block 2224, causing the permanent magnetic lock block 2224 to disengage from the locking block 1412. At this time, the chassis drawer 22 can be pulled out along the slide rail 12 using the pull handle 2211. To remove the chassis cover 21, pull the pull hole 211 upward, so that the movable block 213 overcomes the elastic force of the first spring piece 2131 and the second spring piece 2132 and disengages from the first clamping strip 2213. At the same time, the fixed block 214 disengages from the second clamping strip 2225, and the chassis cover 21 can be removed.

[0054] Temperature sensor 2227 monitors the ambient temperature inside the chassis in real time and transmits the temperature data to the processor. When the temperature data received by the processor exceeds a preset threshold, the output power of intake fan 2212 and exhaust fan 2226 is controlled according to the temperature. The higher the temperature, the faster the speed of intake fan 2212 and exhaust fan 2226, which speeds up air circulation and enhances heat dissipation. When the temperature drops to a normal range, the processor controls the speed of intake fan 2212 and exhaust fan 2226 to reduce energy consumption.

[0055] Under normal circumstances, the electromagnetic switch 14 can only be opened normally after an authorized operator sends an instruction through the processor. At this time, the proximity switch 2214 detects the chassis drawer 22 opening signal, and the chassis drawer 22 can be pulled out normally for maintenance operations. If the electromagnetic switch 14 is opened abnormally without the authorization of the processor, after the proximity switch 2214 detects the chassis drawer 22 opening signal, the processor will immediately send an alarm to the system to remind relevant personnel to pay attention to prevent unauthorized operations from causing data leakage and other security issues. When the device is powered off, the electromagnet 1411 loses its magnetism, causing the permanent magnetic lock block 2224 to be adsorbed on the surface of the electromagnet 1411, so that the electromagnetic switch 14 remains in a locked state, thereby improving the safety of the device.

[0056] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.

The easily disassembled and maintainable embedded industrial computer chassis according to claim 8, characterized in that: The processor controls the industrial computer chassis, the temperature sensor (2227) is used to detect the ambient temperature in the chassis, and the temperature sensor (2227) controls the output power of the air intake fan (2212) and the air outlet fan (2226) according to the ambient temperature in the chassis. The processor can control the opening of the electromagnetic switch (14) while detecting the proximity switch (2214). When the electromagnetic switch (14) is normally opened under the control of the processor, the box body (2) can be normally pulled out when the proximity switch (2214) is opened. When the electromagnetic switch (14) is abnormally opened, an alarm is issued to the system when the box body (2) is pulled out.
