Description

Technical Field

[0001] The present invention relates to the technical field of network detection, and in particular to a network detection device. Background Art

[0002] With the rapid development of information technology, the Internet has penetrated deeper and deeper into all aspects of people's lives and work, and network security issues have become increasingly prominent. Network detection devices play a vital role in ensuring network security. Through various functional modules, such as power modules, antenna modules, database modules and detection modules, they work together to monitor network security in real time, promptly detect and prevent abnormal intrusion behaviors, and maintain the stability and security of the network system. In the actual application scenarios of network detection devices, the stable connection between the network cable and the device is a key link to ensure the normal functioning of the detection function.

[0003] Traditionally, a fixing clip is simply installed on the housing of the device to fix the network cable. Once installed, the fixing clip is in a fixed position and lacks the ability to flexibly respond to changes in the force on the network cable. In daily network use environments, the network cable may be subjected to different degrees of tension due to factors such as inadvertent pulling by people walking, dragging of peripheral equipment, or aging and shrinkage of the network cable itself. When encountering a small tension, the conventional fixing clip can barely maintain the connection between the network cable and the terminal. However, once subjected to a large tension, the fixing clip cannot buffer or transfer the sudden strong tension, causing the tension to act almost entirely directly on the terminal. In this case, the terminal is easily forcibly pulled out of the wiring hole of the device, which causes physical damage to the connection position between the terminal and the wiring hole, which may cause deformation and wear of the metal contacts, or even internal circuit breakage, greatly increasing the maintenance cost and replacement difficulty. On the other hand, once the network cable is accidentally detached, the detection device instantly loses the network data collection capability corresponding to the line, and the network detection work is forced to be interrupted, and the network status cannot be monitored in real time and comprehensively, resulting in a significant reduction in the detection effect. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that most of the network cables are fixed by simply installing a fixing clip on the housing of the device, which lacks the ability to flexibly cope with changes in the stress of the network cable, and to propose a network detection device.

[0011] Preferably, a second protective mechanism is also provided on the rectangular shell. When the first protective mechanism squeezes the network cable downward, the second protective mechanism squeezes the network cable upward synchronously so that the network cable in the rectangular shell is arranged in a Z shape. The second protective mechanism includes a gear meshing with the first rack. The gear is rotatably connected to the rectangular shell through a rotating shaft. The outer surface of the gear is meshed with a second rack. A connecting rod is fixed on the second rack. The connecting rod is slidably connected to the inner wall of the rectangular shell.

[0013] Preferably, an auxiliary mechanism is provided in the fixed shell 1, and the auxiliary mechanism is used to enhance the clamping force of the elastic clamp 2 on the network cable.

[0014] Preferably, the outer surfaces of the second elastic clip and the third elastic clip are both provided with openings, and the network cable slides in the openings.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When the network cable is subjected to a pulling force greater than zero and less than the first threshold, the sliding mechanism can function effectively. The spring sleeved on the crossbar can utilize its own elastic deformation to provide a buffer space for the moving block, so that it can slide flexibly along the crossbar and absorb the slight pulling force from the network cable, thus preventing the pulling force from being directly transmitted to the terminal. This preliminarily ensures that the terminal is not affected by small pulling forces, maintains the stability of the connection between the network cable and the device, reduces the risk of loosening or damage of the terminal due to daily small pulling, and ensures that the network detection work is carried out continuously and stably.

[0016] 2. When the network cable encounters a pulling force greater than the second threshold, the protection mechanism responds quickly. The arc block and the lifting block cooperate precisely through the locking rod and the locking hole. Combined with the telescopic part, the strong pulling force originally concentrated on the terminal is cleverly transferred to other parts of the network cable to prevent the terminal from being pulled out of the wiring hole due to excessive pulling force, thereby protecting the integrity of the connection between the terminal and the wiring hole, reducing the probability of metal contact damage, line breakage and other faults, reducing maintenance costs, and ensuring that the network detection device does not interrupt data collection due to accidental detachment of the network cable, thereby maintaining the continuity of the detection work.

[0017] 3. When the protection mechanism 1 is in action, the protection mechanism 2 will operate synchronously. With the linkage of the rack 1, gear, rack 2 and other components, the network cable in the rectangular shell can be arranged in a Z shape. By changing the force form of the network cable, the tension on the network cable is dispersed to avoid stress concentration at a certain point, further improving the ability of the network cable to resist pulling, enhancing the stability of the connection between the network cable and the device, making network data transmission more reliable, ensuring that the network detection device can obtain network data in real time and accurately, and improving the overall detection effect.

[0018] 4. The auxiliary mechanism in the fixed shell 1 can dynamically adjust the clamping force of the elastic clamp 2 on the network cable. When the device is subjected to external forces such as the pulling of the network cable, the pressure change is transmitted through the hose 2 connected between the fixed tube and the airbag. The airbag is inflated in time to push the elastic clamp 2 to fit the network cable more closely, preventing the network cable from loosening and slipping during the force-bearing process, thereby strengthening the fixing effect of the network cable and ensuring again that the network cable and the device always maintain a stable connection under complex force environments, providing a solid guarantee for the stable operation of the network detection device.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Embodiment 1, refer to Figure 1-Figure 8 A network detection device includes a box shell 1, a card board 11 is fixed in the box shell 1, a support frame 12 is fixed on the top of the card board 11, a power module 13, an antenna module 14 and a database module 15 are installed on the front of the support frame 12 from top to bottom, a detection module 17 and a protection module 18 are installed on the card board 11, transmission modules 16 are installed on both sides of the detection module 17, and a network terminal is formed by two transmission modules 16, a wiring hole 110 is installed on the box shell 1, a terminal 111 is inserted in the wiring hole 110, a network cable 112 is electrically connected to the terminal 111, and the end of the network cable 112 away from the terminal 111 is connected to an external network, and a box door 19 is rotatable on the box shell 1.

[0023] The network detection device further includes: a sliding mechanism disposed on the housing 1, and when the pulling force on the network cable 112 is greater than zero and less than a first threshold, the sliding mechanism is used to provide preliminary protection for the terminal 111. For example, when a pet such as a cat or dog pulls and plays with the network cable 112, the pulling force is less than 1 Newton, which can be considered to be small.

[0024] The network detection device further includes: a protection mechanism 1 installed on the sliding mechanism, when the pulling force is greater than the second threshold value, it can be considered that the pulling force is large, and the protection mechanism 1 is used to transfer the pulling force received by the terminal 111 to the network cable 112. The first threshold value can be equal to the second threshold value, and the first threshold value can also be less than the second threshold value. For example, when the network cable 112 is accidentally tripped, the pulling force is greater than 1 Newton, which can be considered to be large.

[0025] Furthermore, the sliding mechanism includes an L-shaped frame 21 fixed on the box shell 1, a cross bar 22 is fixed between the L-shaped frame 21 and the box shell 1, a moving block 23 is slidably provided on the outer surface of the cross bar 22, a spring 24 is sleeved on the outer surface of the cross bar 22, two ends of the spring 24 are respectively fixedly connected to the L-shaped frame 21 and the moving block 23, a rectangular shell 25 is fixed to the top of the moving block 23, a spring 26 is fixed to the inner wall of the rectangular shell 25, a mounting block 27 is fixed to the end of the spring 26 away from the rectangular shell 25, and an elastic clip 28 is fixed to the side of the mounting block 27 close to the network cable 112.

[0026] During detection, the external network terminal 111 is inserted into the wiring hole 110 through the network cable 112, and the detection device is connected to the external network. A network terminal can be formed through the two transmission modules 16, and a detection system is formed in conjunction with the antenna module 14, the database module 15, the detection module 17 and the protection module 18. It can detect network information while realizing network transmission, so that network attack information can be directly intercepted during network transmission, thereby ensuring the security of network communication and reducing user losses. This is a prior art, so it will not be elaborated here.

[0027] Considering that in the prior art, after the terminal 111 is inserted into the wiring hole 110, a fixing clip is simply installed on the housing of the device to fix the network cable 112. Once subjected to a large tensile force, the fixing clip cannot buffer or transfer the sudden strong tensile force, causing the tensile force to act almost entirely directly on the terminal 111. In this case, the terminal 111 is easily forcibly pulled out of the wiring hole 110 of the device, causing damage to the device and affecting the detection effect. The following improvements are now made: When inserting the terminal 111 into the wiring hole 110, the network cable 112 can be passed through the elastic clip 1 28 first, and the elastic clip 1 28 can well clamp the network cable 112 through the mounting block 27 by using the squeezing force of the spring 26. It should be noted that if Figure 2As shown, a certain distance needs to be reserved for the network cable 112, so that when subjected to tension, the rectangular shell 25 can move a certain distance, and the terminal 111 will not be subjected to tension. After the network cable 112 is clamped by the elastic clamp 28, when the network cable 112 is subjected to a small tension, the network cable 112 will drive the rectangular shell 25 and the moving block 23 to slide backward on the outer surface of the cross bar 22, and squeeze the spring 24. The spring 24 can use its own elastic deformation to provide a buffer space for the moving block 23, so that it can slide flexibly along the cross bar 22 and absorb the slight tension transmitted from the network cable 112.

[0028] A further benefit of adopting the above method is that it can prevent the pulling force from being directly transmitted to the terminal 111, preliminarily ensure that the terminal 111 is not affected by small pulling forces, maintain the stability of the connection between the network and the device, reduce the risk of the terminal 111 loosening or being damaged due to daily small pulling, and ensure that the network detection work is carried out continuously and stably.

[0029] Example 2, refer to Figure 1-Figure 8 A network detection device includes a box shell 1, a card board 11 is fixed in the box shell 1, a support frame 12 is fixed on the top of the card board 11, a power module 13, an antenna module 14 and a database module 15 are installed on the front of the support frame 12 from top to bottom, a detection module 17 and a protection module 18 are installed on the card board 11, transmission modules 16 are installed on both sides of the detection module 17, and a network terminal is formed by two transmission modules 16, a wiring hole 110 is installed on the box shell 1, a terminal 111 is inserted in the wiring hole 110, a network cable 112 is electrically connected to the terminal 111, and the end of the network cable 112 away from the terminal 111 is connected to an external network, and a box door 19 is rotatable on the box shell 1.

[0030] The network detection device further includes: a sliding mechanism disposed on the housing 1 , and when the pulling force applied to the network cable 112 is small, the sliding mechanism is used to provide preliminary protection for the terminal 111 .

[0031] The network detection device further includes: a protection mechanism 1 installed on the sliding mechanism, and when the pulling force is large, the protection mechanism 1 is used to transfer the pulling force exerted on the terminal 111 to the network cable 112 .

[0032] Furthermore, the protection mechanism 1 includes an arc block 31 fixed at the bottom of the moving block 23, a lifting block 32 is provided above the L-shaped frame 21, a locking rod 33 is fixed to the top of the lifting block 32, a locking hole 34 is opened in the middle of the arc surface of the arc block 31, the locking rod 33 is slidably connected to the locking hole 34, and a telescopic part is provided between the L-shaped frame 21 and the lifting block 32.

[0033] Furthermore, the telescopic part includes a liquid storage cylinder 351 fixed on the top of the L-shaped frame 21, a sliding rod 352 is fixed to the bottom of the lifting block 32, a piston disk 353 is fixed to the bottom end of the sliding rod 352, the sliding rod 352 and the piston disk 353 both slide in the liquid storage cylinder 351, a spring 354 is sleeved on the outer surface of the sliding rod 352, and the two ends of the spring 354 are respectively fixedly connected to the liquid storage cylinder 351 and the lifting block 32, and an extrusion part is arranged on the rectangular shell 25.

[0034] Furthermore, the extrusion member includes a hose 361 connected to the liquid storage cylinder 351, a mounting frame 362 is fixed on the rectangular shell 25, a fixed cylinder 363 is fixed to the bottom of the mounting frame 362, one end of the hose 361 away from the liquid storage cylinder 351 is connected to the fixed cylinder 363, a piston disk 2 360 is sliding in the fixed cylinder 363, a lifting rod 364 is fixed to the bottom of the piston disk 2 360, the lifting rod 364 is slidably connected to the fixed cylinder 363, a rack 365 is fixed to the bottom of the lifting rod 364, a spring 4 366 is sleeved on the outer surface of the lifting rod 364, and the two ends of the spring 4 366 are respectively fixedly connected to the piston disk 2 360 and the fixed cylinder 363.

[0035] Furthermore, the extrusion piece also includes an L-shaped rod 367 fixed on the rack 1 365, the L-shaped rod 367 is slidably connected to the inner wall of the rectangular shell 25, a fixed block 1 368 is fixed to the end of the L-shaped rod 367 away from the rack 1 365, an elastic clip 2 369 is fixed to the bottom of the fixed block 1 368, a fixed shell 1 3610 is fixed to the bottom wall of the rectangular shell 25, and the elastic clip 2 369 slides in the fixed shell 1 3610.

[0036] Considering that when the tension is large, the network cable 112 is only clamped by the elastic clip 28, the clamping force is not enough, causing the network cable 112 to slide directly in the elastic clip 28, so that the tension is still transmitted to the terminal 111, thereby causing the terminal 111 to be damaged. The following improvements are now made: The arc block 31 is connected to the moving block 23. When the moving block 23 slides backward, the arc block 31 is also driven to slide together. When the arc block 31 slides to contact the locking rod 33, a downward pressure is generated on the locking rod 33. Since the sliding rod 352 slides in the liquid storage cylinder 351, the sliding rod 352 is driven to slide downward in the liquid storage cylinder 351, squeezing the spring three 354 until the locking rod 33 is inserted into the locking hole 34, locking the arc block 31 and the moving block 23. When the sliding rod 352 moves downward, it also drives the piston plate 1 353 to move downward in the liquid storage cylinder 351, thereby pressing the liquid in the liquid storage cylinder 351. The liquid is squeezed so that it enters the fixed cylinder 363 through the hose 1 361. Since the piston disc 2 360 slides in the fixed cylinder 363, when the liquid enters the mounting frame 362, the piston disc 2 360 is squeezed by the liquid and moves downward, thereby driving the lifting rod 364 and the rack 1 365 to move downward, squeezing the spring 4 366. The rack 1 365 in turn drives the L-shaped rod 367, the fixed block 1 368 and the elastic clip 2 369 to move downward, thereby bending the network cable 112. The network cable 112 can be moved into the fixed shell 1 3610 through the elastic clip 2 369 to compress the network cable 112.

[0037] A further advantage of adopting the above method is that the strong pulling force originally concentrated on the terminal 111 can be cleverly transferred to other parts of the network cable 112, preventing the terminal 111 from being pulled out of the wiring hole 110 due to excessive pulling force, protecting the integrity of the connection between the terminal 111 and the wiring hole 110, reducing the probability of metal contact damage, line breakage and other faults, reducing maintenance costs, ensuring that the network detection device does not interrupt data collection due to accidental detachment of the network cable 112, and maintaining the continuity of the detection work.

[0038] Example 3, refer to Figure 1-Figure 8 A network detection device includes a box shell 1, a card board 11 is fixed in the box shell 1, a support frame 12 is fixed on the top of the card board 11, a power module 13, an antenna module 14 and a database module 15 are installed on the front of the support frame 12 from top to bottom, a detection module 17 and a protection module 18 are installed on the card board 11, transmission modules 16 are installed on both sides of the detection module 17, and a network terminal is formed by two transmission modules 16, a wiring hole 110 is installed on the box shell 1, a terminal 111 is inserted in the wiring hole 110, a network cable 112 is electrically connected to the terminal 111, and the end of the network cable 112 away from the terminal 111 is connected to an external network, and a box door 19 is rotatable on the box shell 1.

[0039] The network detection device further includes: a sliding mechanism disposed on the housing 1, and when the pulling force on the network cable 112 is small, the sliding mechanism is used to provide preliminary protection for the terminal 111; The network detection device further includes: a protection mechanism 1 installed on the sliding mechanism, and when the pulling force is large, the protection mechanism 1 is used to transfer the pulling force exerted on the terminal 111 to the network cable 112 .

[0040] Furthermore, a second protective mechanism is provided on the rectangular shell 25. When the first protective mechanism squeezes the network cable 112 downward, the second protective mechanism simultaneously squeezes the network cable 112 upward so that the network cable 112 located in the rectangular shell 25 is arranged in a Z shape. The second protective mechanism includes a gear 41 meshing with the first rack 365. The gear 41 is rotatably connected to the rectangular shell 25 through a rotating shaft. The outer surface of the gear 41 is meshed with a second rack 42. A connecting rod 43 is fixed on the second rack 42. The connecting rod 43 is slidably connected to the inner wall of the rectangular shell 25. A fixing block 2 44 is fixed to one end of the connecting rod 43 away from the second rack 42. An elastic clip 3 45 is fixed to the top of the second fixing block 44. A fixing shell 2 46 is fixed to the top wall of the rectangular shell 25.

[0041] Furthermore, the second protection mechanism also includes a limit bar 47 fixed to the bottom of the mounting frame 362 , a limit block 48 is slidably disposed on the outer surface of the limit bar 47 , and a fixing rod 49 is fixed between the limit block 48 and the second rack 42 .

[0042] Furthermore, an auxiliary mechanism is provided in the fixed shell 3610, and the auxiliary mechanism is used to enhance the clamping force of the elastic clamp 369 on the network cable 112. The auxiliary mechanism includes an airbag 51 fixed in the fixed shell 3610, and a hose 52 is connected between the fixed tube 363 and the airbag 51.

[0043] Preferably, the outer surfaces of the second elastic clip 369 and the third elastic clip 45 are both provided with openings, and the network cable 112 slides in the openings.

[0044] Since the gear 41 is meshed with the rack 1 365, when the rack 1 365 moves downward, it will drive the gear 41 to rotate, and the gear 41 will drive the rack 2 42 to move upward, and the rack 2 42 will drive the connecting rod 43 to move upward, and the connecting rod 43 will drive the fixed block 2 44 and the elastic clip 3 45 to move upward together, so that the elastic clip 3 45 drives the other part of the network cable 112 to be inserted into the fixed shell 2 46, and the rack 2 42 can be limited by sliding the limit block 48 on the outer surface of the limit bar 47, thereby improving the stability of the rack 2 42 when moving.

[0045] A further advantage of adopting the above method is that with the linkage of components such as rack 1 365, gear 41, and rack 2 42, the network cable 112 located in the rectangular shell 25 can be arranged in a Z shape, and the tension on the network cable 112 can be dispersed by changing the force form of the network cable 112 to avoid stress concentration at a certain point, thereby further improving the ability of the network cable 112 to resist pulling, enhancing the stability of the connection between the network cable 112 and the device, making network data transmission more reliable, ensuring that the network detection device can obtain network data in real time and accurately, and improving the overall detection effect.

[0046] It should be noted that the outer surfaces of the elastic clip 2 369 and the elastic clip 3 45 are both provided with openings, which makes it easy to remove the network cable 112, and when the terminal 111 is inserted into the wiring hole 110, the network cable 112 must also be passed through the elastic clip 2 369 and the elastic clip 3 45. This not only makes it convenient for the elastic clip 2 369 and the elastic clip 3 45 to drive the network cable 112 to bend, but also when subjected to a smaller pulling force, in conjunction with the setting of the elastic clip 1 28, it is easier to pull the rectangular shell 25.

[0047] When the piston disc 2 360 moves downward due to the squeeze of the liquid, it will also squeeze the gas in the fixed cylinder 363, causing the gas to enter the airbag 51 through the hose 2 52, causing the airbag 51 to expand, thereby pushing the elastic clamp 2 369 to fit the network cable 112 more closely, preventing the network cable 112 from loosening and slipping during the force application process, thereby strengthening the fixing effect of the network cable 112, and once again ensuring that the network cable 112 and the device always maintain a firm connection under complex force environments, providing a solid guarantee for the stable operation of the network detection device.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
