[0004] When an existing computer is invaded by a virus, a common situation is that the central processing unit and the hard disk drive will run at an abnormally high speed.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 to 9, the present invention provides a technical solution: a computer network security intelligent protection device, including a chassis housing and a network cable end 29 plugged into a network interface, and further including a cooling fan for cooling the central processor and the hard disk. A base 1 is fixedly connected to the chassis housing, and a network blocking structure for performing a network disconnection operation according to abnormal temperature changes is provided on the base 1;

[0038] The network blocking structure includes a guiding column 4 slidably penetrating through the base 1. An L-shaped turning column 19 fixedly connected to the guiding column 4 and moving horizontally synchronously therewith is provided. One end of the guiding column 4 away from the base 1 is provided with a sliding rheostat 20 electrically connected in series with the cooling fan, and the guiding column 4 is fixedly connected to a resistance sliding piece 201 integrally formed on the sliding rheostat 20;

[0039] The L-shaped turning column 19 is provided with a pressing and separating assembly for separating the network cable end 29 from the network interface, and the base 1 is provided with a dosing assembly for driving the guiding column 4 to move intermittently in the horizontal direction according to temperature changes.

[0040] As Figure 1 , Figure 2 and Figure 3 shown, after the computer is invaded by a virus, when the virus may replicate, spread in the background or communicate with an external server, a large amount of computing resources and storage operations are usually required, which may cause the temperature inside the chassis housing to rise abnormally. Therefore, the dosing assembly is driven by the temperature change inside the chassis housing.

[0041] At the same time, when the dosing assembly operates, it can drive the guiding column 4 and the L-shaped turning column 19 fixedly arranged thereon to move synchronously in the horizontal direction. Among them, when the guiding column 4 moves in the horizontal direction, it can drive the resistance sliding piece 201 to move synchronously, thereby changing the resistance value of the series circuit where the cooling fan is located. Among them, the resistance value of this series circuit decreases, thereby increasing the output power of the cooling fan to improve the heat dissipation effect on components such as the central processor and the hard disk.

[0042] Among them, when the output power of the cooling fan increases, if the temperature inside the chassis housing continues to rise, it indicates at this time that the increase in the temperature inside the chassis housing is not caused by normal use, but by the abnormal high-speed operation of the central processor and the hard disk drive caused by virus invasion. Furthermore, at this time, the guiding column 4 can continue to move in the horizontal direction, thereby driving the pressing and separating assembly to operate through the horizontal movement process of the guiding column 4.

[0043] Meanwhile, when the pressure-separating component is operating, it can separate the network cable end 29 fixedly plugged into the network interface, thereby cutting off the network of the computer device. Among them, some viruses usually need to communicate with external servers or other infected devices through the network to achieve self-propagation or receive instructions. The network-disconnection operation can cut off these communication channels and prevent the further spread of the virus. Moreover, the virus may download other malicious software from the Internet or update its own code. The network-disconnection operation can prevent the virus from downloading new malicious components and reduce its harm.

[0044] Therefore, when the temperature inside the chassis housing rises, the output power of the cooling fan inside the chassis housing can be increased first to improve the heat dissipation effect. However, if the temperature rises abnormally due to virus intrusion, at this time, the pressure-separating component can be driven to operate, thereby cutting off the network connection, preventing important data and personal information from being stolen and leaked, reducing the risk of data leakage, and buying time for subsequent security processing.

[0045] In a relatively preferred embodiment, the discretionary component includes a limit post 2 provided on a base 1, and a horizontal post groove 3 for the horizontal sliding of the limit post 2 is provided on the base 1. An end panel 14 is fixedly connected to the limit post 2, and both the end panel 14 and the limit post 2 are slidably sleeved on a guiding post 4;

[0046] A positioning block 15 is provided on the base 1 and a horizontal sliding groove 16 for the horizontal sliding of the positioning block 15 is provided. A primary temperature memory alloy 18 and a secondary temperature memory alloy 17 are respectively provided on both horizontal sides of the positioning block 15. Both ends of the secondary temperature memory alloy 17 are fixedly connected to the end panel 14 and the positioning block 15 respectively, and both ends of the primary temperature memory alloy 18 are fixedly connected to the inner wall of the base 1 and the positioning block 15 respectively.

[0047] A conical ring 6 is fixedly sleeved on the guiding post 4, and a coaxial spring 5 is sleeved outside the guiding post 4. Both ends of the coaxial spring 5 are fixedly connected to the limit post 2 and the conical ring 6 respectively;

[0048] The conical ring 6 includes an integrally formed conical surface and a right-angled surface, and the conical surface faces the side of the limit post 2. A blocking component for restricting the horizontal movement of the conical ring 6 and the guiding post 4 is provided on the base 1.

[0049] As Figure 1 、 Figure 2 、 Figure 5 and Figure 6 shown, when the temperature inside the chassis housing rises and exceeds the temperature threshold of the secondary temperature memory alloy 17, the secondary temperature memory alloy 17 can be driven to undergo an elongation deformation. Among them, the positioning block 15 is at the end final position of the horizontal sliding groove 16. When the secondary temperature memory alloy 17 elongates, the end panel 14 can be driven to move horizontally.

[0050] Among them, the end panel 14 is fixed with the limit column 2, and a isotropic spring 5 is provided between the limit column 2 and the conical ring 6. When the end panel 14 moves horizontally, the guide column 4 can be driven by the isotropic spring 5 to move horizontally synchronously until the conical ring 6 fixedly mounted on the guide column 4 is restricted by the blocking component and cannot continue to move horizontally. During this process, the horizontal movement distance of the conical ring 6 is limited, but the guide column 4 can still move a certain distance during the elongation deformation of the secondary temperature memory alloy 17, thereby driving the resistance slider 201 at the end of the guide column 4 to move horizontally to change the resistance value of the series circuit where the heat dissipation fan is located, thereby achieving the purpose of increasing the output power of the heat dissipation fan.

[0051] At the same time, if the temperature inside the chassis shell continues to rise to the deformation threshold of the main temperature memory alloy 18, it indicates that the device is running at high speed due to virus invasion, and then the main temperature memory alloy 18 undergoes elongation deformation to drive the end panel 14 to continue to move horizontally, wherein, during the horizontal movement of the end panel 14 and the guide column 4, the conical ring 6 is first restricted by the blocking component and cannot continue to move horizontally, and the isotropic spring 5 gradually undergoes compression deformation, but as the end panel 14 and the limit column 2 continue to move, the conical ring 6 releases the restriction of the blocking component, and then the isotropic spring 5 can quickly restore the deformation, and driven by the isotropic spring 5, the guide column 4 and the L-shaped bend column 19 move rapidly in the horizontal direction for a certain distance, thereby driving the compression component to run through the horizontal movement process of the L-shaped bend column 19 to disconnect the network of the computer device.

[0052] Furthermore, the blocking assembly includes a yielding column 7 arranged on the base 1, and a vertical yielding groove 8 is provided on the base 1 for the yielding column 7 to be slidably connected in the vertical direction, the top of the vertical yielding groove 8 is connected through the middle of the horizontal column groove 3, and a return spring 9 is fixedly connected to the yielding column 7, and one end of the return spring 9 away from the yielding column 7 is fixedly connected to the base 1;

[0053] The top of the said yielding column 7 comprises an integrally formed pointed step portion 10, and the pointed step portion 10 is in sliding contact with the conical ring 6, and the said base 1 is provided with a pressing component for releasing the restriction of the horizontal position of the conical ring 6 by the yielding column 7;

[0054] The pressing assembly includes an angled blocking pin 11 fixedly connected to the end panel 14, the angled blocking pin 11 and the limiting column 2 are arranged in parallel, and a micro-porous groove 12 for the angled blocking pin 11 to slide horizontally is opened on the base 1, and the micro-porous groove 12 is connected with the vertical giving way groove 8;

[0055] The position of the yielding column 7 corresponding to the micro-hole groove 12 is provided with an oblique through groove 13 which is in sliding contact with the oblique angle blocking pin 11 .

[0056] like Figure 1, Figure 2 , Figure 4 and Figure 5 As shown, when the secondary temperature memory alloy 17 undergoes elongation deformation, it can drive the end panel 14, the guide column 4 and the conical ring 6 fixedly mounted on the guide column 4 to move horizontally synchronously until the conical ring 6 collides with the pointed step 10, and then the conical ring 6 and the guide column 4 are restricted from continuing to move horizontally due to the obstruction of the pointed step 10. When the end panel 14 and the limit column 2 continue to move horizontally, the conical ring 6 and the guide column 4 will not continue to move horizontally with the limit column 2, but will drive the isotropic spring 5 to undergo compression deformation.

[0057] At the same time, when the end panel 14 moves horizontally, it can drive the bevel resistance pin 11 to slide in the microporous groove 12, but the elongation deformation of the secondary temperature memory alloy 17 will not drive the bevel resistance pin 11 to contact the oblique through groove 13. When the primary temperature memory alloy 18 undergoes elongation deformation as the temperature continues to rise, it can drive the bevel resistance pin 11 to continue to move on the microporous groove 12 until the end of the bevel resistance pin 11 contacts the oblique through groove 13 and slides against the oblique through groove 13.

[0058] At the same time, the oblique through groove 13 on the yield column 7 can move downward under the compression of the oblique blocking pin 11, thereby driving the reset spring 9 to undergo compression deformation. At this time, the yield column 7 drives the pointed step portion 10 to move downward and return to the vertical yield groove 8, thereby releasing the restriction on the conical ring 6. At this time, the conical ring 6 can move rapidly in the horizontal direction under the elastic potential energy of the same-position spring 5, thereby driving the guide column 4 and the L-shaped crook column 19 to move horizontally synchronously, so as to drive the pressure-sub assembly to operate through the horizontal movement of the L-shaped crook column 19.

[0059] It should be noted that when the temperature inside the chassis shell is normal, the primary temperature memory alloy 18 and the secondary temperature memory alloy 17 can be restored to their initial states in turn, thereby driving the end panel 14 to return to its initial position. During this process, the integrally formed conical surface on the conical ring 6 can be squeezed into contact with the pointed step 10, and then squeeze the pointed step 10 again, so as to drive the conical ring 6 to pass smoothly through the position of the pointed step 10, thereby ensuring that the conical ring 6 can return to its initial position, and the vertical give way groove 8 can restore its deformation when the conical ring 6 passes the position of the pointed step 10, so that when the temperature rises abnormally again in the future, it can respond quickly again, and when the temperature initially rises, it can drive the pointed step 10 to restrict the conical ring 6 again.

[0060] On the basis of the embodiment of the component for dividing, the component for pressing and dividing includes an extension plate 21 fixedly connected to the L-shaped turning post 19. A rectangular groove for the extension plate 21 to slide through is formed in the chassis housing. Two pressing plates 28 that move synchronously towards or away from each other in the vertical direction are provided on the extension plate 21. The two pressing plates 28 jointly clamp and fix the end of the network cable 29, and after the two pressing plates 28 are in pressing contact with the end of the network cable 29, they move in the horizontal direction.

[0061] An installation rod 25 is fixedly connected to the chassis housing. Two vertical plates 24 arranged opposite to each other are provided on the installation rod 25. A first groove for the two vertical plates 24 to be slidably connected in the vertical direction is formed in the installation rod 25. Connecting blocks 27 are provided on both of the two vertical plates 24. A connecting rod 26 is rotatably fixed at one end on the side of the vertical plate 24 facing the connecting block 27 towards the connecting block 27, and the other end of the connecting rod 26 is rotatably fixed on the connecting block 27. A fixed connection is provided between the connecting block 27 and the pressing plate 28.

[0062] A positioning pin 23 is fixedly connected to the side of the vertical plate 24 facing the extension plate 21. A V-shaped positioning groove 22 for the positioning pin 23 to be slidably connected is formed in the extension plate 21. The V-shaped positioning groove 22 includes a horizontally grooved portion and an inclined grooved portion that are integrally formed and connected through.

[0063] As Figure 1 、 Figure 7 、 Figure 8 and Figure 9 shown, when the secondary temperature memory alloy 17 undergoes an elongation deformation to drive the extension column 4, the L-shaped turning post 19, and the extension plate 21 fixedly arranged between the L-shaped turning post 19 to move in the horizontal direction, at this time, the positioning pin 23 slides in the horizontally grooved portion integrally formed in the V-shaped positioning groove 22, and thus the horizontal height of the two vertical plates 24 will not be changed. When the primary temperature memory alloy 18 undergoes an elongation deformation, the L-shaped turning post 19 and the extension plate 21 continue to move in the horizontal direction, thereby driving the positioning pin 23 to slide in the inclined grooved portion integrally formed on the V-shaped positioning groove 22, so as to achieve the purpose of reducing the distance between the two vertical plates 24 by changing the horizontal height of the positioning pin 23.

[0064] Meanwhile, when the two vertical plates 24 move towards each other, it can drive the pressing plate 28 arranged on the connecting block 27 to be in pressing contact with the end of the network cable 29, thereby driving the two pressing plates 28 to complete the clamping and fixing process of the end of the network cable 29. At the same time, as the distance between the two vertical plates 24 is further reduced, and the pressing plate 28 has already been in contact with the end of the network cable 29, the pressing plate 28 cannot continue to move synchronously with the vertical plate 24. At this time, the height change of the vertical plate 24 can drive the connecting rod 26 to deflect, so as to drive the two pressing plates 28 to press the pressing plate 28 and push the end of the network cable 29 to move horizontally along with the pressing plate 28, thereby separating the end of the network cable 29 from the network interface, and thus achieving the purpose of disconnecting the network.

[0065] It should be noted that a torsion spring for driving the connecting block 27 to return to its initial deflected state is provided on the vertical plate 24. This torsion spring is an existing device and a well-known technical means in the art, so it is not illustrated. Thus, under the action of this torsion spring, when the distance between the two vertical plates 24 initially decreases, the pressing plate 28 provided thereon can be driven to correspond to the network cable end 29. When the two pressing plates 28 complete the clamping and fixing of the network cable end 29, as the distance between the two vertical plates 24 further decreases, the purpose of driving the connecting rod 26 to deflect and push the network cable end 29 away from the network interface can be achieved.

[0066] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
