Description

Technical Field

[0001] The utility model relates to the field of network security equipment, in particular to a portable network security isolation device. Background Art

[0002] With the acceleration of digital transformation, network security protection has become a core requirement for ensuring data security. As a key device for achieving physical isolation, portable network security isolation devices are widely used in mobile office, on-site data collection and other scenarios. By cutting off the direct connection between different network environments, they effectively prevent data leakage and network attacks, and provide reliable protection for sensitive information.

[0003] Existing portable network security isolation devices are usually composed of a device body and a data interface. The device body integrates a core processing module, and the data interface is used to connect external devices or networks. When in use, the user connects the external device to the device body through the data interface, and uses the security isolation technology inside the device to achieve isolation between different network environments, thereby ensuring the security of data transmission. The advantage of this type of device is that it has basic network isolation functions, can prevent network attacks and data leakage to a certain extent, and provide users with a relatively safe data transmission environment. Moreover, its portable feature allows users to use it conveniently in different locations, meeting the needs of mobile office and on-site operations; such as a portable network security isolation device with Chinese patent publication number CN220653377U.

[0004] However, the data interfaces of most portable network security isolation devices on the market are directly exposed to the air. Because they have relatively many interfaces, some interfaces are often not used in actual use. At this time, they are easily affected by the external environment when in use. Specifically, dust and other floating objects in the air can easily enter the unused interfaces and remain inside them. A large amount of residual accumulation over a long period of time can easily affect the subsequent connection line plugs, and the plugs will be unplugged when carrying, which makes the interfaces directly exposed and easy for dust and other debris to enter. In order to ensure that the interfaces can still be used smoothly after long-term use, it is urgently needed to improve the existing portable network security isolation devices. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a portable network security isolation device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable network security isolation device, comprising a device body and multiple groups of interfaces, wherein the multiple groups of interfaces are all arranged on a group of outer walls of the device body;

[0007] A protective frame is slidably mounted on the outer wall of the interface of the device body. One end of the protective frame is provided with an opening, and a frame door is movably mounted at the end of the protective frame where the opening is provided.

[0008] Protrusions are mounted on the inner wall of the protective frame, and positioning grooves are formed at the ends of the protrusions. A positioning block corresponding to the positioning groove is movably mounted on the outer wall of the device body for fixing the position of the protective frame. An elastic member for driving the positioning block is provided inside the device body. An unlocking assembly for releasing the positioning of the positioning block is provided on the protective frame.

[0009] By adopting the above technical solution, the slidable and fixed functions of the protective frame are realized. The interface can be exposed during use and covered in time after use, effectively preventing dust and sundries from entering the unused interface, ensuring the long-term stable use of the interface, and also preventing users from accidentally knocking against the connector, improving the safety of the connector during the use of the device.

[0010] Further, a plurality of groups of protective plates are mounted on the outer wall of the device body on one side of the interface, and the distance between the outer wall of the protective plate and the frame door is greater than the distance between the interface it protects and the frame door.

[0011] By adopting the above technical solution, the protective plates can support and limit the connector when connecting the circuit, preventing the connector from falling off due to extrusion and pulling when the circuit enters the protective frame, and further improving the stability and reliability of data transmission during the use of the device.

[0012] Further, the outer end of the protective plate protrudes from the device body, and the distance between the outer end of the protective plate and the inner wall of the protective frame is 15 - 20 mm.

[0013] By adopting the above technical solution, it can not only ensure the support and limiting effect of the protective plate on the connector, but also not affect the normal sliding of the protective frame and the overall protection performance due to too large or too small a distance, optimizing the protection function of the protective plate and enhancing the practicability of the device.

[0014] Further, the cross-section of the protective frame is designed in a "C" shape. When the protective frame is fixed, the protective frame will cover a plurality of groups of interfaces.

[0015] By adopting the above technical solution, during daily use and carrying, it can effectively block external pollutants such as dust and sundries, greatly reducing the erosion of the external environment on the interface, protecting the interface, extending the service life of the interface, and ensuring the long-term stable operation of the device.

[0016] Further, the side corner of the positioning block away from the frame door is designed with an oblique angle, and the side corner of the protrusion close to the frame door is designed with an oblique angle. During the process of the protrusion sliding towards the positioning block following the protective frame, the oblique angle at the end of the protrusion will contact the oblique angle at the end of the positioning block.

[0017] By adopting the above technical solution, the positioning block can smoothly enter the inside of the device body under the push of the protrusion, which facilitates the sliding operation of the protection frame and ensures the accuracy and stability of the positioning, ensuring that the protection frame can be reliably fixed in a suitable position to protect the interface.

[0018] Furthermore, the width of the positioning block is smaller than the width of the positioning groove, and the side wall of the positioning block is in contact with the outer wall of the positioning groove on one side close to the frame door, and the opening corners of the end of the positioning groove are all designed to be beveled.

[0019] By adopting the above technical solution, the positioning block is prevented from shaking in the positioning groove, which further ensures that the protection frame is firmly positioned, so that the protection frame will not be displaced when protecting the interface, thereby improving the reliability of device protection.

[0020] Furthermore, the unlocking assembly is an unlocking block slidably mounted on the protective frame and slidably connected to the positioning groove, and the outer end of the unlocking block is located outside the protective frame, and the other end is attached to the end of the positioning block, and the width of the unlocking block is greater than the width of the positioning block.

[0021] By adopting the above technical solution, the user can easily release the engagement between the positioning block and the positioning groove by pressing the outer end of the unlocking block, thereby realizing the free sliding of the protective frame. The operation is simple and convenient, which improves the convenience of user use and makes it convenient for the user to open or close the protective frame at any time to use or protect the interface.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model discloses a sliding protective frame and a frame door, so that the interface can be exposed when the device is in use, and can be covered in time after use, so as to avoid the interface being directly exposed to the air, prevent dust and debris from entering the unused interface, reduce the impact on the subsequent connection line plug, and ensure the long-term and stable use of the interface. At the same time, the protective frame will cover and protect the connector to prevent the user from accidentally knocking the connector, thereby further improving the safety of the connector when the device is in use. At the same time, through the provision of the protective plate, when connecting the line, the connector is supported and restricted, so as to prevent the connector from falling off due to squeezing or pulling when the line enters the protective frame.

[0024] When the utility model needs to be carried subsequently, the protection frame can be reset, the positioning block is snapped into the positioning groove under the action of the spring, the protection frame is fixed, the frame door is automatically closed or can be closed manually, and magnets at the frame door and the opening of the protection frame attract each other, effectively blocking external dust from entering the protection frame, protecting the interface, and making it convenient to carry.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The utility model focuses on solving the problem that the data interface of the existing portable network security isolation device is easily affected by the external environment. Through the careful design and layout of each component, the dual improvement of protection performance and ease of use is achieved.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] A portable network security isolation device, such as Figure 1 - Figure 7 As shown, it is mainly composed of a device body 1 and multiple groups of interfaces 2; the device body 1 is the basic carrier of the entire device, integrating the core processing module, responsible for data processing and transmission security isolation;

[0037] The multiple groups of interfaces 2 are arranged on a group of outer walls of the device body 1, which are key channels for connecting external devices or networks and undertake the important task of data input and output; at the same time, the protection frame 3 is slidably installed on the outer wall of the device body 1 where the interfaces 2 are arranged, and effectively protects the interfaces 2 by sliding itself;

[0038] Specifically, the protective frame 3 is designed with a "C"-shaped cross-section, which can completely wrap and block multiple groups of interfaces 2; during daily use and carrying, it can effectively block external pollutants such as dust and debris, greatly reducing the erosion of the external environment on the interfaces 2, protecting the interfaces 2 from oxidation and corrosion, extending the service life of the interfaces 2, ensuring the long-term stable operation of the device, and at the same time preventing users from accidentally touching the connectors, resulting in the disconnection or even damage of the connectors.

[0039] In the present utility model, the frame door 4 is movably installed at the end of the protective frame 3 where there is an opening. During the sliding process of the protective frame 3, the frame door 4 can be opened and closed automatically or manually, further enhancing the protection effect on the interfaces 2;

[0040] Exemplarily, the convex blocks 5 provided on the inner wall of the protective frame 3 and the positioning blocks 7 on the outer wall of the device body 1 cooperate with each other to achieve the precise positioning of the protective frame 3;

[0041] Specifically, the positioning groove 6 at the end of the convex block 5 provides an accurate card slot for the positioning block 7. When the protective frame 3 slides to a suitable position, the positioning block 7 is accurately snapped into the positioning groove 6 under the action of the elastic member in the device body 1, firmly fixing the protective frame 3 to ensure that the protective frame 3 will not slide randomly during use and stably protect the interfaces 2;

[0042] In some examples, the elastic member can be a spring 8, and its two ends are respectively connected to the positioning block 7 and the device body 1.

[0043] Of course, in other examples, the elastic member can also be an elastic rod or other tools with elasticity that can reset the positioning block 7.

[0044] At the same time, the chamfer design at the corner of the positioning block 7 away from the frame door 4 and the corner of the convex block 5 close to the frame door 4 plays a key role during the reset process of the protective frame 3; when the protective frame 3 slides, the chamfer at the end of the convex block 5 contacts the chamfer at the end of the positioning block 7. This chamfer design enables the positioning block 7 to smoothly enter the interior of the device body 1 under the push of the convex block 5, facilitating the sliding operation of the protective frame 3, and at the same time ensuring the accuracy and stability of the positioning;

[0045] It should be noted that the width of the positioning block 7 in the present utility model is smaller than the width of the positioning groove 6, and the side wall of the positioning block 7 is attached to the outer wall of the positioning groove 6 close to the frame door 4. The opening corner at the end of the positioning groove 6 is chamfered. These detailed designs further optimize the positioning structure, prevent the positioning block 7 from shaking in the positioning groove 6, and ensure the firm positioning of the protective frame 3.

[0046] In some examples, the unlocking assembly is composed of an unlocking block 9 slidably installed on the protective frame 3;

[0047] Among them, the outer end of the unlocking block 9 is located outside the protective frame 3, which is convenient for user operation; the other end is in contact with the end of the positioning block 7, and the width of the unlocking block 9 is greater than the width of the positioning block 7; when the protective frame 3 needs to be slid, the user presses the outer end of the unlocking block 9, and the unlocking block 9 pushes the positioning block 7 inward, so that the positioning block 7 overcomes the elastic force of the elastic member and slides toward the inside of the device body 1, thereby releasing the engagement between the positioning block 7 and the positioning groove 6, realizing the free sliding of the protective frame 3, and the operation is simple and convenient, which improves the convenience of user use.

[0048] Of course, in other examples, the unlocking component can also be an automated unlocker, specifically a miniature electric push rod, a miniature cylinder, or the like, which can realize a tool for pushing the positioning block 7 into the device body 1, and this is not directly and completely restricted in the present invention.

[0049] In the present invention, multiple sets of protective plates 21 are installed on the outer wall of the device body 1 on one side of the interface 2, which provide additional protection for the interface 2;

[0050] Specifically, the distance between the outer wall of the protective plate 21 and the frame door 4 is greater than the distance between the interface 2 it protects and the frame door 4, and the outer end of the protective plate 21 protrudes from the device body 1, and the distance between the outer end and the inner wall of the protective frame 3 is 15-20mm, ensuring that the line can pass through the distance between the protective plate 21 and the protective frame 3, avoiding the setting of the protective plate 21 causing the line to be unable to connect; when connecting the line, the outer wall of the connector contacts the protective plate 21 to support and restrict the connector; in this way, during the sliding process of the protective frame 3, even if the line is squeezed, the protective plate 21 can effectively prevent the connector from falling off, thereby ensuring the stability of data transmission.

[0051] The working principle of the utility model is as follows: when the device is needed, the device body 1 is first placed on the work surface, and then the outer end of the unlocking block 9 is pressed so that the end thereof pushes the positioning block 7 to slide into the inside of the device body 1. During this process, the positioning block 7 squeezes the spring 8, causing the spring 8 to be in a compressed state until the positioning block 7 completely enters the device body 1. At the same time, because the width of the unlocking block 9 is greater than that of the positioning block 7, the unlocking block 9 will not enter the device body 1, ensuring that the subsequent protective frame 3 can slide smoothly.

[0052] Then the user pushes the protection frame 3 until all the interfaces 2 are exposed. During this process, the inner wall of the frame door 4 is in contact with the side wall of the device body 1, so that the frame door 4 will open automatically. The user then fully opens the frame door 4. At this time, the user can connect the connectors such as the data cable and the network cable to the interface 2, and then push the protection frame 3 in the opposite direction to make the protection frame 3 start to slide to its original position. During this process, the protection frame 3 will contact the data cable, the network cable and other lines, causing them to bend, so that these lines will enter the protection frame 3 until the protection frame 3 is reset. At this time, the connector and the interface 2 will be shielded by the protection frame 3, effectively reducing the impact of the external environment on the interface 2;

[0053] Furthermore, when the connector is installed, the outer wall of the connector will contact the protective plate 21. It should be noted that the spacing between the protective plate 21 and the corresponding interface 2 is determined according to the actual connector width, ensuring that the side wall of the connector will contact the corresponding protective plate 21 after installation, so that when the line contacts the protective frame 3, the protective plate 21 will support and restrict the connector to prevent the connector from falling off when the line enters the protective frame 3;

[0054] When the device is used, it will improve network security. At the same time, because the protection frame 3 protects the line and the connector, it will also effectively prevent the user from accidentally bumping into the connector, further improving the safety of the connector when the device is in use;

[0055] When the device needs to be carried, first expose the interface 2 according to the above operation, then unplug the connector, and then reset the protection frame 3. During the reset of the protection frame 3, the bevel of the protrusion 5 will contact the bevel of the positioning block 7. Since the protection frame 3 has not been reset to the corresponding position at this time, it is still sliding, causing the positioning block 7 to enter the inside of the device body 1 under the action of the bevel of the protrusion 5. When the protection frame 3 is completely reset, the position of the positioning block 7 will correspond to the positioning groove 6. The positioning block 7 will enter the positioning groove 6 under the action of the spring 8, and the position of the protection frame 3 is restricted. The protective frame 3 cannot continue to slide. At this time, the user can lift the device body 1 through the handle on the outer wall of the protective frame 3 to carry it. At this time, the outer wall of the device body 1 where the interface 2 is opened is in an upward state, so that the frame door 4 will automatically close. If it does not close automatically, the user manually closes it. Because magnetically attractive magnets are provided on the outer wall of the frame door 4 and the outer wall of the protective frame 3 where the opening is set, the position of the frame door 4 after closing is restricted by the magnet, causing the opening of the protective frame 3 to be closed, thereby reducing the risk of a large amount of external dust entering the protective frame 3 when carrying the device and affecting the subsequent use of the interface 2.

[0056] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
