Description

Technical Field

[0001] The present invention relates to the technical field of computer network security devices, and specifically relates to a computer network security device. Background Art

[0002] Computer network security devices are usually physically composed of network connection devices and transmission media such as network cards, hubs, switches, routers, network cables, and RJ45 connectors. Network devices also include devices such as repeaters, bridges, routers, gateways, firewalls, and switches. In an enterprise, switches are an important part of enterprise network devices.

[0003] Currently, during the use of existing computer network security devices, it is necessary to regularly check the connection status of the lines and the operation status of the cooling fans. However, computer network security devices are usually placed in the corners of computer equipment. Therefore, it is somewhat inconvenient to regularly check the fans and the line connections.

[0019] 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.

[0020] Embodiment 1: Please refer to Figures 1 - 3 , Figure 5 , Figure 6 and Figure 10 , the present invention provides a technical solution: a computer network security device, including a network security device body 1, a fan self-check mechanism 2 is arranged on the right side of the network security device body 1, and a line self-check mechanism 3 is arranged in front of the network security device body 1; The fan self-check mechanism 2 includes a fan self-check unit 21. The fan self-check unit 21 is arranged on the right side of the network security device body 1, and the fan self-check unit 21 can check the operation of the fan.

[0021] As a further limitation of the fan self-check mechanism 2 of the present invention, the fan self-check unit 21 includes a rectangular box 2102. The left side surface of the rectangular box 2102 is fixedly connected to the right side surface of the network security device body 1. A cooling fan 2106 is fixedly connected to the front surface of the rectangular box 2102. A first ventilation pipe 2105 is fixedly communicated with the front surface of the cooling fan 2106. A rectangular box 2107 and an exhaust box 2101 are fixedly connected to the right side surface of the network security device body 1. The back surface of the rectangular box 2107 is fixedly connected to the front surface of the exhaust box 2101. One end of the first ventilation pipe 2105 close to the rectangular box 2107 is fixedly communicated with the back surface of the rectangular box 2107. A second ventilation pipe 2108 is fixedly communicated with the upper surface of the rectangular box 2107 and the upper surface of the exhaust box 2101. A T-shaped limiting block 2115 is fixedly connected to the inner top wall of the rectangular box 2107. A baffle 2116 is arranged outside the T-shaped limiting block 2115. The baffle 2116 is arranged inside the rectangular box 2107. A T-shaped sliding groove 2117 is opened on the upper surface of the baffle 2116. The outer surface of the T-shaped limiting block 2115 is slidably connected to the inside of the T-shaped sliding groove 2117. A first return spring 2110 is fixedly connected to the inner top wall of the exhaust box 2101. The bottom end of the first return spring 2110 is fixedly connected to a lifting block 2112. First air leakage ports 2111 are opened on the right side surface and the upper surface of the lifting block 2112, and the two first air leakage ports 2111 are communicated with each other. The outer surface of the lifting block 2112 is slidably connected to the inside of the exhaust box 2101. A warning flag 2103 is fixedly connected to the upper surface of the lifting block 2112. A second air leakage port 2104 is opened on the right side surface of the exhaust box 2101. By arranging the fan self-check unit 21, the fan self-check unit 21 can self-check the operation of the cooling fan 2106 in the network security device body 1, and can timely transmit the information that the cooling fan 2106 stops running to the outside world. This not only eliminates the regular self-check work of workers, but also avoids the problem that the temperature inside the network security device body 1 is too high due to the long-term shutdown of the cooling fan 2106.

[0022] Please refer to Figure 2 and Figure 5 , a plurality of identical air inlets 2122 are opened on the left side surface of the network security device body 1, and a plurality of identical air outlets 2118 are opened on the right side surface of the network security device body 1. Each air outlet 2118 is arranged in the inner cavity of the rectangular box 2102. By arranging the air inlets 2122, the air inlets 2122 can guide the outside air into the inside of the network security device body 1, and the existence of the air outlets 2118 can guide the heat generated when the internal electronic components of the network security device body 1 operate out.

[0023] Please refer to Figure 2 Figure 2 , on the left side of the network security device body 1, two groups of first circular card slots 2120 are provided. The number of each group of first circular card slots 2120 is two. Inside each first circular card slot 2120, a first circular card block 2121 is clamped. The left ends of the two groups of first circular card blocks 2121 are fixedly connected together with a dust-proof plate 2119. By providing the first circular card slots 2120, the first circular card blocks 2121 and the dust-proof plate 2119, the dust-proof plate 2119 can be used to filter the gas about to enter the air inlet 2122, preventing dust from entering the inside of the network security device body 1. Moreover, the existence of the first circular card blocks 2121 and the first circular card slots 2120 can facilitate the removal of the dust-proof plate 2119 to clean the dust on the surface of the dust-proof plate 2119.

[0024] The specific implementation of this embodiment is as follows: When the network security device body 1 is working, the cooling fan 2106 will run, and the heat generated by the internal electronic devices of the network security device body 1 will be taken out through the air outlet 2118. And the outside air will enter the inside of the network security device body 1 through the air inlet 2122. After the cooling fan 2106 takes out the heat inside the network security device body 1, the heat will enter the inside of the rectangular box 2107 through the first ventilation pipe 2105 along with the air. And the air entering the inside of the rectangular box 2107 will enter the inside of the fastening unit 22 through the third ventilation pipe 2206 again. When there is enough air inside the fastening unit 22, the air pressure inside the fastening unit 22 will increase. Therefore, the fastening unit 22 will pull the baffle 2116 to move horizontally. At this time, the baffle 2116 is not below the second ventilation pipe 2108, and the air pressure inside the fastening unit 22 is greater than the outside. Therefore, the air that enters the inside of the rectangular box 2107 again will not flow towards the fastening unit 22. Instead, it will move upward and enter the inside of the exhaust box 2101 through the second ventilation pipe 2108. Finally, it will enter the inside of the lifting block 2112 through the first air release port 2111 opened on the upper surface of the lifting block 2112. At this time, the first air release port 2111 opened on the right side of the lifting block 2112 is blocked by the inner wall of the exhaust box 2101. Therefore, the gas inside the lifting block 2112 cannot flow outwards. As the gas continues to enter, the air pressure inside the exhaust box 2101 will slowly be higher than the outside. When the pressure of the exhaust box 2101 is greater than the elastic potential energy of the first return spring 2110, it will push the lifting block 2112 to move downward. During the downward movement of the lifting block 2112, it will drive the warning flag 2103 to move downward together until it is lower than the uppermost part of the network security device body 1. When the first air release port 2111 opened on the right side of the lifting block 2112 coincides with the second air release port 2104 opened on the right side of the exhaust box 2101, the gas inside the lifting block 2112 will escape outwards. When the cooling fan 2106 stops running, without the continuous entry of gas, the lifting block 2112 will move upward under the action of the first return spring 2110, thereby driving the warning flag 2103 to move upward synchronously. Thus, a warning signal can be sent to the outside world.

[0025] Embodiment 2: Please refer to Figures 1 - 4 and Figure 6 This invention provides a technical solution: A computer network security device. This invention makes corresponding improvements to the technical problems mentioned in the background technology. The fan self-check mechanism 2 includes a fastening unit 22. The fastening unit 22 is arranged in front of the network security device body 1. The fastening unit 22 and the fan self-check unit 21 cooperate with each other, and the fan can be used to provide fastening power for the fastening unit 22.

[0026] As a further limitation of the fan self-check mechanism 2 of the present invention, the fastening unit 22 includes a first supercharging box 2204. The back surface of the first supercharging box 2204 is fixedly connected to the front surface of the network security device body 1. The right side surface of the first supercharging box 2204 and the front surface of the rectangular box 2107 are fixedly communicated with a third ventilation pipe 2206. Two second return springs 2211 are fixedly connected to the inner top wall of the first supercharging box 2204. The bottom ends of the two second return springs 2211 are fixedly connected to a lifting plate 2212. The upper surface of the lifting plate 2212 is fixedly connected to a lifting shaft 2209. The top end of the lifting shaft 2209 penetrates through the first supercharging box 2204 and extends above the first supercharging box 2204. The outer surface of the lifting shaft 2209 is slidably connected to the inside of the first supercharging box 2204. A rotating shaft 2210 is rotatably connected to the inner wall of the network security device body 1. A rotating plate 2205 is fixedly connected to the outer surface of the rotating shaft 2210. A transmission rope 2216 is fixedly connected to the right side surface of the rotating plate 2205. The end of the transmission rope 2216 close to the baffle 2116 penetrates through the rectangular box 2107 and extends into the inside of the rectangular box 2107. The end of the transmission rope 2216 close to the baffle 2116 is fixedly connected to the front surface of the baffle 2116. The left side surface of the first supercharging box 2204 is fixedly communicated with a second supercharging box 2201. The back surface of the second supercharging box 2201 is fixedly connected to the front surface of the network security device body 1. An extrusion block 2213 is slidably connected to the inside of the second supercharging box 2201. A fixed rubber pad 2214 is fixedly connected to the inner wall of the second supercharging box 2201. A folding rubber pad 2215 is fixedly connected to the outer surface of the fixed rubber pad 2214. The right side surface of the folding rubber pad 2215 is in contact with the inner wall of the second supercharging box 2201. By providing the fastening unit 22, the fastening unit 22 can utilize the wind generated during the operation of the cooling fan 2106 in the network security device body 1 to further reinforce the lines connected to the network security device body 1, making the lines less likely to fall off the network security device body 1.

[0027] Please refer to Figure 4 , a first exhaust pipe 2208 is fixedly communicated with the front surface of the first supercharging box 2204. A first threaded cap 2203 is threadedly connected to the outer surface of the first exhaust pipe 2208. A second exhaust pipe 2207 is fixedly communicated with the upper surface of the second supercharging box 2201. A second threaded cap 2202 is threadedly connected to the outer surface of the second exhaust pipe 2207. By providing the first exhaust pipe 2208 and the second exhaust pipe 2207, the gas inside the first supercharging box 2204 and the second supercharging box 2201 can be discharged respectively when the device is not in use, and the presence of the first threaded cap 2203 and the second threaded cap 2202 can ensure that the gas inside the first supercharging box 2204 and the second supercharging box 2201 will not overflow outward during the operation of the device.

[0028] Please refer to Figure 5and Figure 6 , a limiting frame 2109 is fixedly connected to the right side surface of the network security device body 1. Two first limiting shafts 2113 are rotatably connected to the inner wall of the limiting frame 2109. The outer surface of each first limiting shaft 2113 is in contact with the outer surface of the transmission rope 2216. By providing the first limiting shaft 2113, the first limiting shaft 2113 can be used to limit the left and right position directions of the transmission rope 2216.

[0029] Please refer to Figure 6 , a second limiting shaft 2114 is rotatably connected to the inner wall of the limiting frame 2109. The outer surface of the second limiting shaft 2114 is in contact with the outer surface of the transmission rope 2216. By using the second limiting shaft 2114, the lowest position of the transmission rope 2216 can be limited, and the rotation characteristic of the second limiting shaft 2114 can reduce the friction force when the transmission rope 2216 is pulled.

[0030] The specific implementation manner of this embodiment is as follows: When the gas generated during the operation of the cooling fan 2106 enters the interior of the first pressurizing tank 2204 through the third ventilation pipe 2206, the gas will first blow the folding rubber pad 2215 to fold, so that the gas can enter the interior of the second pressurizing tank 2201. It should be understood here that the fixed rubber pad 2214 is fixed on the inner wall of the second pressurizing tank 2201, while the folding rubber pad 2215 is fixed on the fixed rubber pad 2214. Therefore, there is no connection relationship between the folding rubber pad 2215 and the second pressurizing tank 2201. So when the folding rubber pad 2215 is blown by the gas, it will fold towards the interior of the second pressurizing tank 2201. At this time, the folding rubber pad 2215 will not block the communication port between the second pressurizing tank 2201 and the first pressurizing tank 2204. Thus, the gas can enter the interior of the second pressurizing tank 2201. As the gas in the second pressurizing tank 2201 continues to enter, the air pressure inside the second pressurizing tank 2201 will be higher than the outside, so as to push the extrusion block 2213 to move, enabling the extrusion block 2213 to contact the right side surface of the first transmission gear 306 and apply a thrust to the first transmission gear 306. Moreover, a layer of rubber covers the surface of the extrusion block 2213 that contacts the first transmission gear 306. Therefore, the friction between the first transmission gear 306 and the extrusion block 2213 can be increased, and the power received when the first transmission gear 306 rotates can be increased. It should be understood here that if the wires connected to the network security device body 1 want to move, they must drive the first transmission gear 306 to rotate. Therefore, applying a thrust to the first transmission gear 306 can indirectly fasten the connected wires, so that when the wires accidentally fall, they will be subjected to a greater pulling force and are more difficult to accidentally fall. When the air pressure inside the second pressurizing tank 2201 is too high, it will be more difficult for the gas inside the first pressurizing tank 2204 to push the folding rubber pad 2215 to open and enter the interior of the second pressurizing tank 2201. Therefore, the gas will gradually accumulate in the first pressurizing tank 2204. When the air pressure inside the first pressurizing tank 2204 is too high, it will push the lifting plate 2212 and the lifting shaft 2209 to move upward. Thus, the lifting shaft 2209 can be used to push the rotating plate 2205 to rotate around the center of the rotating shaft 2210. And when the rotating plate 2205 rotates, it will pull the transmission rope 2216. By using the transmission rope 2216, the baffle 2116 can be pulled forward. At this time, the baffle 2116 will no longer block the air from entering the second ventilation pipe 2108, and thus further flow to the fan self-check unit 21. It should be understood here that since the baffle 2116 no longer blocks the air from entering the second ventilation pipe 2108, the air pressure inside the first pressurizing tank 2204 will decrease to some extent. The air pressure received by the lifting plate 2212 and the lifting shaft 2209 will also be less than the elastic force of the second return spring 2211 itself. Therefore, the second return spring 2211 will push the lifting plate 2212 to reset downward, and the rotating plate 2205 will also reset under its own gravity.However, at this time, the baffle 2116 will not receive any power. Even if the rotating plate 2205 resets, it cannot push the baffle 2116 to reset through the transmission rope 2216, and the gas can still enter the fan self-check unit 21 through the second ventilation pipe 2108. In addition, the rotating plate 2205 is divided into two parts by the rotating shaft 2210, and the area of the right half of the rotating plate 2205 is significantly larger than that of the left half. However, the density of the left half of the rotating plate 2205 is relatively high. Therefore, it can reset by the weight of its own left half. When the staff wants to reset the baffle 2116, they only need to stand up the network security device body 1 and use gravity to make it reset.

[0031] Embodiment 3: Please refer to Figures 1 - 4 and Figures 6 - 9 , the present invention provides a technical solution: a computer network security device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The line self-check mechanism 3 cooperates with the fan self-check mechanism 2, and the line self-check mechanism 3 can self-check the connection status of the lines installed on the network security device body 1.

[0032] As a further limitation of the circuit self-checking mechanism 3 of the present invention, the circuit self-checking mechanism 3 includes two groups of rectangular blocks 305, and the number of each group of rectangular blocks 305 is two. The back surface of each rectangular block 305 is fixedly connected to the front surface of the network security device body 1. A long shaft 301 is rotatably connected to the inner wall of each group of rectangular blocks 305. The right end of one of the long shafts 301 is fixedly connected to a first transmission gear 306. The right side surface of the first transmission gear 306 is in contact with the left side surface of the extrusion block 2213. A first rectangular plate 312 and a second rectangular plate 313 are respectively fixedly connected to the front surface of the network security device body 1. A first rotating shaft 309 is rotatably connected to the inner wall of the first rectangular plate 312. A steering gear 307 is fixedly connected to the outer surface of the first rotating shaft 309. The outer surface of the steering gear 307 meshes with the outer surface of the first transmission gear 306. A second rotating shaft 310 is rotatably connected to the inner wall of the second rectangular plate 313. A second transmission gear 308 is fixedly connected to the outer surface of the second rotating shaft 310. The outer surface of the second transmission gear 308 meshes with the outer surface of the steering gear 307. A rotating plate 311 is fixedly connected to the outer surface of the second rotating shaft 310. A short shaft 314 is rotatably connected to the inner wall of the second rectangular plate 313. A warning plate 304 is fixedly connected to the outer surface of the short shaft 314. A rectangular card slot 315 is opened on the right side surface of the second rectangular plate 313. A first fixing frame 303 and a second fixing frame 302 are respectively arranged in front of the network security device body 1. The upper surface of the first fixing frame 303 and the bottom surface of the second fixing frame 302 are respectively in contact with the outer surfaces of the two long shafts 301. Two second circular clamping blocks 319 are fixedly connected to the bottom surface of the first fixing frame 303. Two second circular card slots 316 are opened on the upper surface of the second fixing frame 302. The outer surface of each second circular clamping block 319 is clamped inside the second circular card slot 316. By setting the circuit self-checking mechanism 3, the circuit self-checking mechanism 3 can be used to self-check the looseness of the circuit. By setting the fan self-checking unit 21, the fastening unit 22 and the circuit self-checking mechanism 3, the problem that workers need to regularly check the operation of the cooling fan 2106 and the connection state of the circuit in the network security device body 1 can be effectively avoided.

[0033] Two third circular card slots 318 are opened on the front surface of the network security device body 1. Two semi-circular clamping blocks 317 are fixedly connected to the back surfaces of the first fixing frame 303 and the second fixing frame 302. The outer surface of each semi-circular clamping block 317 is clamped inside the third circular card slot 318. By setting the third circular card slot 318 and the semi-circular clamping block 317, the first fixing frame 303 and the second fixing frame 302 can be fixed on the front surface of the network security device body 1.

[0034] The specific implementation of this embodiment is as follows: When it is necessary to install a circuit in the network security device body 1, the first fixing frame 303 and the second fixing frame 302 can be removed. Then, place the connector of the circuit between the first fixing frame 303 and the second fixing frame 302. Then, the second circular clamping block 319 fixed to the bottom surface of the first fixing frame 303 is clamped inside the second circular clamping groove 316 opened on the upper surface of the second fixing frame 302, whereby the circuit can be fixed. Subsequently, the semi-circular clamping blocks 317 fixed to the back surface of the first fixing frame 303 and the semi-circular clamping blocks 317 fixed to the back surface of the second fixing frame 302 are uniformly clamped inside the third circular clamping groove 318. When the semi-circular clamping block 317 is clamped inside the third circular clamping groove 318, the circuit between the first fixing frame 303 and the second fixing frame 302 will also be smoothly inserted into the interface of the network security device body 1. During this process, since the first fixing frame 303 and the second fixing frame 302 are in contact with the long shaft 301, the first fixing frame 303 and the second fixing frame 302 will push the long shaft 301 to rotate, and at the same time, drive the first transmission gear 306 to rotate. It should be understood here that a layer of rubber is covered on the surface of the long shaft 301 to increase the friction between the long shaft 301 and the first fixing frame 303 and the second fixing frame 302. Therefore, when the first fixing frame 303 and the second fixing frame 302 move, they will drive the long shaft 301 and the first transmission gear 306 to rotate by using the rubber covered on the surface of the long shaft 301. Note that at this time, the circuit is in the just-connected state, so the network security device body 1 is not running, and thus the fan self-check mechanism 2 is not running either. Similarly, the extrusion block 2213 will not apply pressure to the first transmission gear 306, so the first transmission gear 306 can rotate very easily. Subsequently, control the network security device body 1 to run, and the heat dissipation fan 2106 of the network security device body 1 will also rotate. Thereby, the extrusion block 2213 structure in the fastening unit 22 can be used to apply pressure to the first transmission gear 306, increasing the power received when the first transmission gear 306 rotates, thereby limiting the first fixing frame 303 and the second fixing frame 302 and increasing the power received when the circuit becomes loose. When the circuit still becomes loose due to a large amount of power, it will drive the first fixing frame 303 and the second fixing frame 302 to move forward a certain distance towards the network security device body 1. This process will drive the long shaft 301 to rotate, thereby driving the first transmission gear 306 to rotate. The first transmission gear 306 will drive the steering gear 307 to rotate by using the meshing relationship between the two. Moreover, the number of teeth on the surface of the first transmission gear 306 is twice the number of teeth on the surface of the steering gear 307. Therefore, no matter how many degrees the first transmission gear 306 rotates, the steering gear 307 will rotate twice the number of degrees. In addition, the steering gear 307 will synchronously drive the second transmission gear 308 and the second rotating shaft 310 to rotate, thereby driving the rotating plate 311 to rotate.The protruding circular block fixed to the back of the rotating plate 311 will squeeze the warning plate 304 to rotate around the center of the short shaft 314 when rotating. It should be understood here that the warning plate 304 is divided into left and right parts by the short shaft 314. The protruding circular block on the back of the rotating plate 311 will only contact the right half of the warning plate 304 when rotating. As the rotating plate 311 continues to rotate, the right half of the warning plate 304 will be clamped inside the rectangular card slot 315, enabling the warning plate 304 to stand for a long time. It should be ensured here that when the warning plate 304 is clamped inside the rectangular card slot 315, the surface of the warning plate 304 is in contact with the inner wall of the first rectangular plate 312. However, at this time, the warning plate 304 is subject to the thrust of the rotating plate 311, and the thrust of the rotating plate 311 is greater than the frictional force between the warning plate 304 and the first rectangular plate 312. Therefore, the warning plate 304 can be pushed to be clamped in the rectangular card slot 315. When the rotating plate 311 no longer contacts the warning plate 304, the warning plate 304 is only subject to the frictional force with the first rectangular plate 312 at this time. Therefore, under the action of the frictional force, the warning plate 304 can be ensured to stand for a long time. It should be understood here that it is not that the warning plate 304 standing completely upright represents that the circuit has a loosening problem, but that when the warning plate 304 moves upward a certain distance out of the network security device body 1, it represents that the circuit has a loosening problem. From this, it can be understood that the more the warning plate 304 exposes the network security device body 1, the more serious the circuit loosening problem is.
