Description

Technical Field

[0001] This utility model relates to the field of network security technology, specifically to an industrial control network security isolation device with a protective mechanism. Background Technology

[0002] Network security refers to the protection of the hardware, software, and data of a network system from damage, alteration, or disclosure due to accidental or malicious causes, ensuring the continuous, reliable, and normal operation of the system and uninterrupted network services.

[0003] Currently, both industrial and enterprise users install network security isolation devices to ensure network security during daily operations. The most common network security device is the network isolation device (WAN device). This device physically isolates and blocks all network connections that could potentially attack the internal network, preventing external attackers from directly intruding, attacking, or damaging the internal network, thus protecting the security of internal hosts. While existing WAN devices offer network security protection, they still have significant shortcomings in practical use, such as:

[0004] Network gateways serve to protect network security, but they lack their own protective mechanisms. Furthermore, individual network gateway devices range in price from tens of thousands to hundreds of thousands of yuan, making them precision equipment. Damage to them can result in high maintenance costs. For example, network gateways have numerous exposed interfaces. While connected interfaces provide effective protection, unconnected interfaces, due to prolonged exposure and the complexities of factory environments, accumulate excessive lint and impurities, making them prone to damage.

[0005] Therefore, an industrial control network security isolation device with protective mechanisms is now being designed to address such shortcomings. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an industrial control network security isolation device with a protective mechanism, solving the problem that existing network security isolation devices lack a protective mechanism.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an industrial control network security isolation device with a protective mechanism, comprising an outer protective frame and a network gate body, wherein an inner protective frame is provided on the inner side of the outer protective frame, and the network gate body is installed on the inner side of the inner protective frame. Both sides of the rear part of the inner cavity of the inner protective frame are rotatably connected to a horizontal rotating rod through openings. A diamond-shaped pressure strip is fixedly connected to the surface of the horizontal rotating rod, and the diamond-shaped pressure strip is in contact with the network gate body.

[0008] Preferably, the surface of the outer protective frame is provided with a rectangular socket for use with the gate body, and a plurality of rectangular sockets are provided. Both sides of the bottom of the inner cavity of the outer protective frame are provided with docking bottom openings.

[0009] Preferably, sliding frames are fixedly connected to both sides of the bottom of the inner protective frame, and the sliding frames are located inside the docking bottom opening. A sliding block is slidably installed on the inner side of the sliding frame, and a supporting bottom frame is fixedly connected to the bottom of the sliding block.

[0010] Preferably, the inner side of the rectangular socket is provided with a sealing groove that extends to the bottom of the outer protective frame, a sealing baffle is slidably installed on the inner side of the sealing groove, and a positioning slot extending to the rear is provided on the surface of the sealing baffle.

[0011] Preferably, a curved frame is fixedly connected between the bottoms of the two supporting base frames, and a plug-in block is fixedly connected to the surface of the curved frame for use with the positioning slot and the sealing baffle, and a plurality of plug-in blocks are provided.

[0012] Beneficial effects

[0013] This invention provides an industrial control network security isolation device with a protective mechanism. Compared with existing technologies, it has the following advantages:

[0014] (1) The industrial control network security isolation device with protective mechanism is used by setting an inner protective frame inside the outer protective frame and setting the network gate body inside the inner protective frame, and using diamond pressure strips. After the network gate body is installed inside the inner protective frame, the rotating diamond pressure strips can squeeze and fix the network gate body to ensure stability during use. At the same time, the outer and inner protective frames wrap the network gate body, which can effectively protect it and prevent heavy objects from directly hitting the network gate body in daily use, thus improving the safety of the network gate body itself.

[0015] (2) The industrial control network security isolation device with protective mechanism has a sealing baffle installed on the inside of the rectangular socket and a positioning slot opened on the surface of the sealing baffle. It is used in conjunction with a bent frame and plug-in blocks. The structure can use the back-and-forth moving support base frame to engage with the bottom of the outer protective frame, thereby fixing the inner protective frame inside the outer protective frame. At the same time, the plug-in blocks can be inserted into the inside of the positioning slot to position the opened sealing baffle. Meanwhile, the remaining plug-in blocks are positioned by sealing the bottom of the sealing baffle, effectively protecting the security of the remaining interfaces of the network gate body.
