Description

Technical Field

[0001] This invention relates to the field of network security monitoring devices, and in particular to a network security monitoring device with anti-vandalism function. Background Technology

[0002] Network monitoring is the monitoring and control of computers within a local area network (LAN). Networks and the Internet not only serve as a communication bridge within enterprises but also as an important channel for enterprises to conduct various business transactions with external parties. Network monitoring products are mainly divided into two types: monitoring software and monitoring hardware. Through network monitoring devices, network information can be monitored in real time, which can effectively ensure people's correct use of the Internet.

[0003] Chinese patent document CN214799504U discloses a network security monitoring device with anti-vandalism function, including a base plate, controller, auxiliary components, monitoring device body, protective mechanism, power cord, guide frame, buffer spring and suction cup. The device incorporates a protective mechanism within the base plate, where a force-bearing plate can drive a fan to move up and down, improving the airflow and heat dissipation of the monitoring device body. The force-bearing plate also provides protection for the monitoring device body, preventing damage from external forces and extending its lifespan. Furthermore, when the force-bearing plate is subjected to external pressure, the buffer bladder expands, providing secondary protection for the monitoring device body. The auxiliary components are located at the upper part of the base plate, and the clamps on both sides of the base plate facilitate the fixing and disassembly of the monitoring device body, saving time and facilitating maintenance. However, in actual use, when the device is impacted, the buffer bladder requires a certain amount of time to expand, causing the monitoring device body to be impacted first. Additionally, if the device falls, the impact force may be significant, potentially causing the monitoring device body to detach from the protective structure and damage it. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, by setting a limiting device and a positioning device, when the network security monitoring device body needs to be placed into the inner cavity of the outer shell for protection, the network security monitoring device body is placed on the upper end of the support plate and the support plate is driven to move downward. The support plate squeezes the hydraulic device to send hydraulic oil into the inner cavity of the limiting device, so that the limiting device fixes the network security monitoring device body. In addition, during the downward movement of the support plate, the positioning device will also drive the network security monitoring device body to fix the network security monitoring device body, which improves the reliability of the device. At the same time, when the outer surface of the outer shell is subjected to a certain impact, the limiting device and the positioning device will play a certain buffering role for the network security monitoring device body, avoiding damage to the network security monitoring device body due to excessive impact force, and improving the service life of the network security monitoring device.

[0017] 2. In this invention, by setting a fixing device, when the support plate moves downward, the elastic steel strip bends and becomes elastic. At the same time, the positioning rope will be wound up under the action of the positioning mechanism. When the support plate moves to the corresponding position, no more force is applied to the support plate. At this time, the positioning rope cannot be extended under the action of the positioning mechanism, so that the positioning rope, through the connecting plate, prevents the two elastic steel strips from returning to a state of distance, thereby preventing the support plate from moving upward. When it is necessary to remove the network security monitoring device body, the pull rod is pulled, so that the pull rod drives the positioning mechanism to move through the pull plate, so that the positioning mechanism no longer restricts the positioning rope. At this time, the elastic steel strip will push the support plate upward through the connecting plate, which improves the stability of the device. Attached Figure Description

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1

[0033] like Figure 1 - Figure 9As shown, this embodiment discloses a network security monitoring device with anti-vandalism function, including a housing 1. A connection hole 11 is provided on one side of the outer surface of the housing 1. Slide grooves 12 are provided on all four sides of the inner cavity surface of the housing 1. Two dust covers 2 are provided at the upper end of the housing 1. Two buckling mechanisms 21 are provided at the upper middle of the two dust covers 2. The network security monitoring device body 3 is provided in the middle of the inner cavity of the housing 1. A support plate 4 is provided at the lower end of the network security monitoring device body 3. Slide plates 41 that are slidably connected to the inner cavity surface of the slide grooves 12 are provided on all four sides of the outer surface of the support plate 4. Limiting devices 5 are provided at the upper middle of the four slide plates 41. A hydraulic device 6 is provided at the lower middle of the support plate 4. Positioning devices 7 are provided at the four corners of the upper end of the support plate 4.

[0034] Specifically, the buckling mechanism 21 is existing technology and can fix the two dust covers 2. When the network security monitoring device body 3 is placed in the middle of the inner cavity of the outer shell 1, the two dust covers 2 can be put together and fixed by the two buckling mechanisms 21 to prevent more dust from entering the inner cavity of the outer shell 1.

[0035] In order to activate the limit device 5 and limit the network security monitoring device body 3, such as... Figure 4 As shown, the hydraulic device 6 includes a hydraulic frame 61 fixedly connected to the middle of the lower surface of the inner cavity of the outer shell 1. A piston 62 is provided in the middle of the inner cavity of the hydraulic frame 61. Four connecting pipes 63 are evenly arranged on the outer surface of the hydraulic frame 61. Each of the four connecting pipes 63 has a telescopic pipe 64 fixedly connected to the inner wall of the slide plate 41 at its upper end, and the upper end of the telescopic pipe 64 extends to the upper part of the slide plate 41.

[0036] Specifically, when the network security monitoring device body 3 needs to be placed into the inner cavity of the outer shell 1 for protection, the network security monitoring device body 3 is placed on the upper end of the support plate 4 and the network security monitoring device body 3 is pressed, which causes the network security monitoring device body 3 to drive the support plate 4 to move downward. When the support plate 4 moves downward, it will drive the piston 62 to move downward, which will cause the piston 62 to squeeze the hydraulic oil in the lower part of the inner cavity of the hydraulic frame 61, so that the hydraulic oil in the inner cavity of the hydraulic frame 61 flows into the telescopic tube 64 through the four connecting pipes 63, and then the hydraulic oil in the telescopic tube 64 enters the inner cavity of the limiting device 5.

[0037] Furthermore, when the support plate 4 moves upward, since the wall of the telescopic tube 64 is folded, the telescopic tube 64 will also extend when the support plate 4 moves upward, so that the upper end of the telescopic tube 64 is always connected to the outer surface of the limiting device 5.

[0038] To limit the network security monitoring device body 3, and to provide cushioning when the outer surfaces of the four sides of the outer casing 1 are impacted, such as... Figure 5- Figure 6 As shown, the limiting device 5 includes a fixed frame 51 fixedly connected to the upper end of the slide plate 41. A push rod 52 is provided in the middle of the inner cavity of the fixed frame 51, and the end of the push rod 52 away from the telescopic tube 64 extends to the outside of the fixed frame 51. A connecting rod 53 is provided in the middle of the inner cavity of the push rod 52, and the end of the connecting rod 53 away from the telescopic tube 64 extends to the outside of the push rod 52. Two springs 54 fixedly connected to the inner cavity surface of the push rod 52 are provided on the side of the outer surface of the connecting rod 53 near the telescopic tube 64. A fixing plate 55 is provided on the side of the outer surface of the connecting rod 53 away from the telescopic tube 64. Rubber particles 56 are arranged in an array on the side of the outer surface of the fixing plate 55 away from the telescopic tube 64.

[0039] Furthermore, the lower end of the fixed frame 51, away from the body 3 of the network security monitoring device, is fixedly connected to the upper part of the outer surface of the telescopic tube 64, and the inner cavity of the fixed frame 51 is connected to the inner cavity of the telescopic tube 64.

[0040] Specifically, when the hydraulic oil in the inner cavity of the hydraulic frame 61 enters the inner cavity of the fixed frame 51 away from the network security monitoring device body 3 through the telescopic tube 64, the hydraulic oil will push the push rod 52 to move towards the side closer to the network security monitoring device body 3. Under the action of the spring 54, the push rod 52 will push the connecting rod 53 and the fixed plate 55 to move towards the side closer to the network security monitoring device body 3.

[0041] Furthermore, during the downward movement of the network security monitoring device body 3, the outer surface of the fixing plate 55 may come into contact with the outer surface of the network security monitoring device body 3. However, the network security monitoring device body 3 will continue to move downward, causing the hydraulic oil in the telescopic tube 64 to continue entering the inner cavity of the fixing frame 51 to push the push rod 52 to move. At this time, since the connecting rod 53, which is fixedly connected to the fixing plate 55, no longer moves, the push rod 52 will squeeze the spring 54, causing the spring 54 to compress. The elastic force of the spring 54 will increase the force at the connection between the outer surface of the fixing plate 55 and the outer surface of the network security monitoring device body 3. When the network security monitoring device body 3 moves downward to the corresponding position, the four limiting devices 5 will fix the network security monitoring device body 3 to the upper middle part of the support plate 4.

[0042] Furthermore, the rubber particles 56 arrayed on the outer surface of the fixing plate 55 are used to increase the friction between the outer surface of the fixing plate 55 and the outer surface of the network security monitoring device body 3.

[0043] Furthermore, when one of the four outer surfaces of the outer casing 1 is impacted, the spring 54 can provide a certain degree of cushioning.

[0044] To further secure the network security monitoring device body 3 at different heights, and to provide some cushioning in the event of a fall with the outer casing 1 impacting downwards, such as... Figure 7 - Figure 8 As shown, the positioning device 7 includes a positioning block 71 fixedly connected to the upper end of the support plate 4. A limiting mechanism 72 is provided at the upper end of the positioning block 71. A connecting block 73 is provided in the middle of the side of the outer surface of the limiting mechanism 72 away from the network security monitoring device body 3. A telescopic rod 74 is provided at the end of the connecting block 73 away from the network security monitoring device body 3 and rotatably connected to the lower surface of the inner cavity of the outer shell 1. A fixing handle 75 is provided on the upper part of the side of the outer surface of the limiting mechanism 72 close to the network security monitoring device body 3.

[0045] Specifically, when it is necessary to remove the network security monitoring device body 3 from the inner cavity of the outer shell 1, the support plate 4 will move upward into the inner cavity of the outer shell 1. Since the telescopic rod 74 is relatively short, after the support plate 4 drives the positioning block 71 and the limiting mechanism 72 to move upward a certain distance, the telescopic rod 74 will pull the limiting mechanism 72 to rotate through the connecting block 73. This will cause the limiting mechanism 72 to rotate relative to the positioning block 71 to the side away from the network security monitoring device body 3. This will cause the limiting mechanism 72 to drive the fixing handle 75 to rotate. After the four fixing handles 75 have moved 90 degrees, the network security monitoring device body 3 can be put in or taken out.

[0046] Furthermore, when the network security monitoring device body 3 needs to be placed into the inner cavity of the outer shell 1, the telescopic rod 74 will retract as the support plate 4 moves downward. After the telescopic rod 74 has retracted, since the support plate 4 will continue to move downward, the telescopic rod 74 will push the limiting mechanism 72 to rotate towards the side closer to the network security monitoring device body 3 through the connecting block 73. This will cause the lower end of the limiting mechanism 72 to re-contact the upper end of the positioning block 71. At this time, the fixing handle 75 of the four positioning devices 7 will fix the network security monitoring device body 3 again.

[0047] In order to provide some cushioning for the network security monitoring device body 3 when it falls and the outer casing 1 collides downwards, such as... Figure 8As shown, the limiting mechanism 72 includes a connecting frame 721 that is rotatably connected to the side of the outer surface of the positioning block 71 away from the network security monitoring device body 3. A limiting frame 722 is provided in the middle of the inner cavity of the connecting frame 721. Two limiting blocks 723 are evenly arranged on the inner surface of the limiting frame 722. A support rod 724 is provided at the lower end of the limiting frame 722. A spring 725 that is fixedly connected to the lower surface of the inner cavity of the connecting frame 721 is wound around the outer surface of the support rod 724. The upper end of the spring 725 is fixedly connected to the lower end of the limiting frame 722. A positioning member 726 is provided in the middle of the inner cavity of the limiting frame 722.

[0048] In order to fix the main body 3 of the network security monitoring device at different heights, such as Figure 9 As shown, the positioning component 726 includes a second positioning block 7261 fixedly connected to the side of the outer surface of the fixed handle 75 away from the main body 3 of the network security monitoring device. Positioning slots 7262 are provided on both sides of the lower part of the outer surface of the second positioning block 7261. A trapezoidal block 7263 adapted to the first limiting block 723 is provided on the side of the inner cavity of the two positioning slots 7262 that is far apart from each other. A spring 7264 that is close to each other is provided on the side of the two trapezoidal blocks 7263 that is close to each other. A connecting rope 7266 fixedly connected to the side of the outer surface of the two trapezoidal blocks 7263 that is close to each other is provided in the middle of the inner cavity of the two springs 7264. A pressure rod 7265 fixedly connected to the two connecting ropes 7266 is provided in the middle of the second positioning block 7261.

[0049] Specifically, during the process of fixing the network security monitoring device body 3 with the fixing handle 75, due to the different heights of different network security monitoring device bodies 3, the lower end of the fixing handle 75 may not contact the upper end of the network security monitoring device body 3, which is not conducive to fixing the network security monitoring device body 3. Therefore, the positioning member 726 can be pressed to move downward. During the downward movement of the positioning member 726, the inclined surface on the trapezoidal block 7263 will contact the outer surface of the limiting block 723 and cause the trapezoidal block 7263 to compress the spring 7264. The limiting block 723 will not obstruct the movement of the positioning member 726. When the outer surface of the fixing handle 75 contacts the upper end of the network security monitoring device body 3, the trapezoidal block 7263 will enter the gap between the two limiting blocks 723 under the push of the spring 7264. At this time, since the upper end of the trapezoidal block 7263 contacts the lower end of one of the limiting blocks 723, the limiting block 723 will restrict the positioning member 726 to move upward through the trapezoidal block 7263, thereby fixing the network security monitoring device body 3 with the spring 725.

[0050] Furthermore, when the height of the network security monitoring device body 3 is too high, the pressure rod 7265 can be used to move the trapezoidal blocks 7263 on both sides closer to each other via the connecting rope 7266. At the same time, the spring 7264 will be compressed, causing the trapezoidal blocks 7263 to retract into the inner cavity of the positioning groove 7262. At this time, the positioning member 726 can be pushed upward, thereby fixing the handle 75 to fix the network security monitoring device body 3 at different heights. When the positioning member 726 moves to the corresponding position, it no longer applies force to the pressure rod 7265. At this time, the spring 7264 will push the trapezoidal blocks 7263 back to the original position. At the same time, the trapezoidal blocks 7263 will drive the pressure rod 7265 back to the original position via the connecting rope 7266.

[0051] Furthermore, when the positioning component 726 is pressed down, the support rod 724 will press against the limiting frame 722, preventing the limiting frame 722 from moving downward and compressing the spring 725. When the outer shell 1 is upside down and collides with an object, the spring 725 will pull the positioning component 726 under its own elasticity, preventing the positioning component 726 from moving quickly toward the connecting frame 721. This allows the fixing handle 75 to provide a certain buffering effect on the network security monitoring device body 3, preventing the network security monitoring device body 3 from being damaged by excessive impact.

[0052] In summary, the specific implementation method is as follows: When the network security monitoring device body 3 needs to be placed into the inner cavity of the outer shell 1 for protection, the network security monitoring device body 3 is placed on the upper end of the support plate 4 and the support plate 4 is driven to move downward, so that the support plate 4 squeezes the hydraulic device 6 to enter the inner cavity of the limiting device 5, so that the limiting device 5 fixes the network security monitoring device body 3. In addition, during the downward movement of the support plate 4, the positioning device 7 will also be driven to fix the network security monitoring device body 3, which improves the reliability of the device. At the same time, when the outer surface of the outer shell 1 is subjected to a certain impact, the limiting device 5 and the positioning device 7 will play a certain buffering role for the network security monitoring device body 3, preventing the network security monitoring device body 3 from being damaged by excessive impact force.

[0053] Example 2

[0054] This embodiment further improves upon Embodiment 1 by modifying the support plate 4, such as... Figure 10 - Figure 12 As shown, fixing devices 8 are provided on both sides of the lower end of the support plate 4.

[0055] In order to fix the support plate 4 to the fixing device 8, and in turn, to limit the limiting device 5 via the hydraulic device 6, and simultaneously limit the positioning device 7, the limiting device 5 and the positioning device 7 are used to fix the network security monitoring device body 3. Figure 10 As shown, the fixing device 8 includes a support block 81 fixedly connected to the lower surface of the inner cavity of the outer shell 1. Elastic steel bars 82 are provided on both sides of the upper end of the support block 81. A connecting plate 84 fixedly connected to the lower end of the support plate 4 is provided at the upper end of the two elastic steel bars 82. A positioning rope 85 is provided in the middle of the lower end of the connecting plate 84. A positioning mechanism 83 is provided in the middle of the two elastic steel bars 82. A pull rod 86 slidably connected to the inner wall of the outer shell 1 is provided on the side of the positioning mechanism 83 away from the support block 81. The end of the pull rod 86 away from the support block 81 extends to the outside of the outer shell 1. A pull plate 861 is provided on the outer surface of the pull rod 86 near the support block 81.

[0056] Specifically, when the support plate 4 moves downward, the elastic steel strip 82 bends and becomes elastic. At the same time, the positioning rope 85 is wound up under the action of the positioning mechanism 83. When the support plate 4 moves to the corresponding position, no more force is applied to the support plate 4. At this time, the positioning rope 85 cannot extend under the action of the positioning mechanism 83, so that the positioning rope 85 prevents the two elastic steel strips 82 from returning to a state of separation through the connecting plate 84. When it is necessary to remove the network security monitoring device body 3, the pull rod 86 is pulled, so that the pull rod 86 drives the positioning mechanism 83 to move through the pull plate 861, so that the positioning mechanism 83 no longer restricts the positioning rope 85. At this time, the elastic steel strip 82 will push the support plate 4 upward through the connecting plate 84.

[0057] In order to fix the support plate 4, such as Figure 11 - Figure 12As shown, the positioning mechanism 83 includes a transmission rod 831. A support plate 832 is provided on the outer surface of the transmission rod 831 away from the support block 81. A support frame 8321, which is fixedly connected to the lower surface of the inner cavity of the outer shell 1, is provided on the lower part of the outer surface of the support plate 832. A winding wheel 833 is provided on the outer surface of the transmission rod 831 near the support block 81. A torsion spring 834, which is fixedly connected to the outer surface of the transmission rod 831, is provided on the inner cavity of the support plate 832 away from the support block 81. A ratchet 835 is provided on the inner cavity of the support plate 832 near the support block 81. Limiting blocks 836 are provided on both sides of the inner cavity surface of 835. On the outer surface of the two limiting blocks 836, which are far apart from each other, springs 837 are fixedly connected to the inner cavity surface of the support plate 832. Connecting ropes 838 are provided in the middle of the inner cavity of the two springs 837, which are fixedly connected to the outer surface of the two limiting blocks 836 respectively. The ends of the two connecting ropes 838 that are far apart from each other extend to the outside of the support plate 832. The ends of the two connecting ropes 838 that are far away from the support block 81 are fixedly connected to the outer surface of the pull plate 861 on the side close to the support block 81.

[0058] Specifically, when the support plate 4 moves downward, the torsion spring 834 will drive the transmission rod 831 to rotate, which in turn causes the transmission rod 831 to drive the winding wheel 833 to rotate and wind up the positioning rope 85. At this time, since the arc surface on the second limit block 836 is in contact with the arc surface of the ratchet 835, it will not hinder the ratchet 835 from rotating with the transmission rod 831. The third spring 837 will ensure that the surface of the second limit block 836 is always in contact with the surface of the ratchet 835.

[0059] Furthermore, when the support plate 4 moves downward to the corresponding position, the two elastic steel bars 82 will tend to drive the positioning rope 85 upward. However, at this time, since the plane on the limit block 836 contacts the plane on the ratchet 835, the limit block 836 restricts the ratchet 835 from rotating, which in turn restricts the transmission rod 831 from rotating, thus preventing the positioning rope 85 from extending.

[0060] Furthermore, when it is necessary to remove the network security monitoring device body 3 from the inner cavity of the support plate 4, pull the lever 86, causing the lever 86 to drive the two connecting ropes 838 to move through the pull plate 861. In turn, the two connecting ropes 838 drive the two limiting blocks 836 to move away from the ratchet 835. When the two limiting blocks 836 move to the corresponding positions, they no longer restrict the rotation of the ratchet 835. This allows the elastic steel bar 82 to extend the positioning rope 85 through the connecting plate 84. While the positioning rope 85 is extending, it will drive the transmission rod 831 to rotate through the winding wheel 833. This will cause the transmission rod 831 to rotate the torsion spring 834, causing the torsion spring 834 to wind up and generate elasticity, so that the positioning rope 85 can be wound up when the support plate 4 moves downward again.

[0061] In summary, the specific implementation method is as follows: When the support plate 4 moves downward, the elastic steel strip 82 bends and becomes elastic. At the same time, the positioning rope 85 is wound up under the action of the positioning mechanism 83. When the support plate 4 moves to the corresponding position, no force is applied to the support plate 4. At this time, the positioning rope 85 cannot extend under the action of the positioning mechanism 83, so that the positioning rope 85 prevents the two elastic steel strips 82 from returning to a state of separation through the connecting plate 84, thereby preventing the support plate 4 from moving upward. When it is necessary to remove the network security monitoring device body 3, the pull rod 86 is pulled, so that the pull rod 86 drives the positioning mechanism 83 to move through the pull plate 861, so that the positioning mechanism 83 no longer restricts the positioning rope 85. At this time, the elastic steel strip 82 will push the support plate 4 upward through the connecting plate 84, which improves the reliability of the device.
