[0002] As a kind of modern intelligent electronic equipment integrating numerical calculation, logic calculation and storage memory function, computer plays a core role in the daily work of government, enterprise and individual. With the deepening of informatization, the data value stored in computer is increasingly prominent, and data security protection becomes the top priority. In prior art, computer host is usually equipped with several universal serial bus (USB) interfaces or other data interfaces, for connecting keyboard, mouse, printer and other peripherals or carrying out data transmission. However, these open interfaces are also the main source of data leakage, and if there is no effective physical protection, unauthorized personnel can insert mobile storage device to copy confidential files at will, or damage system security by implanting malicious hardware.

[0003] The existing computer interface security device usually adopts closed cover plate or integral protection box structure, and prevents the interface from being abused by physical shielding. For example, a computer interface security device capable of preventing computer data from being stolen, Chinese patent CN202120281571.2, although the scheme can play a dustproof and theftproof role when computer is idle, it has a significant technical defect: protection and use cannot be considered. When the user needs to connect mouse, keyboard or authorized data line, the protection cover must be completely opened or removed, resulting in complete exposure of the interface. At this time, if a criminal removes the data line of the peripheral device being used and inserts illegal equipment, or performs illegal operation on the adjacent idle interface, the original protection device will be useless. In addition, some existing devices are welded or designed in integral linkage mode, which cannot be operated independently for single interface, and once damaged, it is extremely difficult to maintain, greatly reducing the flexibility of use and the reliability of protection. Therefore, it is necessary to improve the existing technology to solve the problem that the existing computer interface protection device cannot achieve closed protection in the use state of the interface.

Compared with the prior art, the utility model has the following remarkable beneficial effects: first, each data interface is equipped with an independent protection cover, realizing independent protection of the partition. When a certain interface needs to be used and the corresponding protection cover is opened, the protection cover of other interfaces can remain in the closed and locked state, without interfering with each other, and the fine management level of protection is improved. Secondly, the slot design in the middle of the protection cover is a key innovation, which allows the data line to pass through, and at the same time, by using the size difference between the data connector and the data line, the inner side wall can abut and limit the data connector from being pulled out when the protection cover is closed. This makes the interface connect the external device for normal work, and its physical connection state (anti-illegal removal and replacement) is effectively locked, completely eliminating the security blind area of the traditional scheme "exposed when used".

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0023] The existing computer interface protection technology usually adopts a whole cover plate structure, which has significant technical limitations: when any one data interface of the computer needs to be used, the whole cover plate must be completely opened, resulting in the remaining idle interfaces being exposed in an unprotected environment at the same time. More importantly, in the use state of the data interface inserting an external device (such as a mouse, a keyboard or a U disk), due to the obstruction of the data line or the connector, the whole cover plate cannot be closed and locked, so that the interface loses physical protection during data transmission, and security incidents caused by illegal removal of devices or insertion of illegal storage media are likely to occur.

[0024] Based on this, in order to improve the problems in the related art, the present application provides a protective device for computer data protection, such as Figures 1 to 6As shown: the device is applied to the computer host 100 provided with multiple data interfaces 110, comprising: a mounting assembly 300 fixedly installed on the computer host 100; a protective cover assembly 400 comprising multiple protective covers 410 corresponding to the number of data interfaces 110; the rear end of each protective cover 410 is rotationally connected with the mounting assembly 300, so that the protective cover 410 can be independently flipped open or closed relative to the computer host 100; the middle part of each protective cover 410 is provided with a slot 411 extending through in the closing direction of the protective cover 410, and the slot 411 extends from the front end edge of the protective cover 410 to the center; and a locking assembly 500, the locking assembly 500 comprises a lock hook 510 arranged at the front end of the protective cover 410 and a lock box 520 fixedly installed on the panel of the computer host 100, and the lock box 520 is provided with a locking mechanism 530; when the protective cover 410 is in the closed state, the lock hook 510 cooperates with the lock box 520 and is locked by the locking mechanism 530.

[0025] Among them, the mounting assembly 300 serves as a base and is fixed to the data interface area of the computer host 100 by a mechanical connection mode. The protective cover assembly 400 is designed independently in a split type, and each data interface 110 is equipped with an independent protective cover 410, so that the operation state of a single interface will not affect the protection state of the adjacent interface. The slot 411 is a long narrow gap on the protective cover 410 body, and its extension direction is consistent with the length direction of the protective cover 410, forming a channel for the data line 210 to pass through. The locking assembly 500 limits the opening degree of freedom of the protective cover 410 after closing by mechanical engagement of the lock hook 510 and the lock box 520.

[0026] The technical scheme realizes the independent protection of the data interface and the locking protection in the use state through the cooperation of the independently arranged protective cover 410 and the slot 411. The slot 411 takes advantage of the size difference between the data line 210 and the data connector to allow the data line 210 to pass out while blocking the connector. When connecting external devices, the protective cover 410 can still be closed, and due to the locking cooperation of the lock hook 510 and the lock box 520, the protective cover 410 physically suppresses the internal data connector, preventing it from being pulled out. This structure ensures the normal connection of the data line 210 while blocking the physical contact of the interface, thereby maintaining the same level of physical security protection as when the device is idle during device use. Compared with the traditional technology, this design effectively eliminates the physical security blind spot during data transmission, and improves the anti-theft and anti-damage ability of the computer terminal in complex environments.

[0027] Optionally, in some embodiments, as Figure 6As shown, the inner part of the protective cover 410 is formed with a receiving cavity 412, the height of which is adapted to the height of the data connector 200 inserted into the data interface 110, the width of the slot 411 is set to be adapted to the diameter of the data line 210 at the tail of the data connector 200, and the width of the slot 411 is smaller than the minimum lateral dimension of the data connector 200; when the protective cover 410 is in the closed state and the data connector 200 is inserted into the data interface 110, the inner side wall of the protective cover 410 abuts against the end of the data connector 200 to limit the displacement of the data connector 200 in the pulling-out direction, and the data line 210 at the tail of the data connector 200 passes out through the slot 411.

[0028] The receiving cavity 412 is a space formed by the inner wall of the protective cover 410 and the panel of the computer host 100, and the spatial dimension is set according to the physical specifications of the standard USB connector or other data connectors. The width dimension of the slot 411 constitutes a physical screening mechanism, which is designed to be greater than the diameter of the commonly used data line 210 but smaller than the width of the data connector 200. When the protective cover 410 is closed, the data connector 200 is located in the receiving cavity 412, and the solid structures on both sides of the slot 411 form a stop surface. If the data connector 200 is subjected to an outward pulling force, the end thereof will mechanically interfere with the inner side wall of the protective cover 410, thereby preventing displacement.

[0029] This embodiment prevents the data connector 200 from being illegally pulled out by using the mechanical interference principle through precise size matching. The protective cover 410 is not only a shielding component but also a force receiving component that directly opposes the pulling-out force. This design effectively prevents malicious personnel from removing critical peripherals such as an encrypted dongle, a special keyboard or mouse, or from attacking through plugging and unplugging actions without damaging the device. By enclosing the connector in the receiving cavity 412 and using the limiting action of the slot 411, a firm physical defense line is constructed.

[0030] Optionally, in some embodiments, as shown in Figure 3 and Figure 4 The mounting assembly 300 includes a mounting seat 310 provided with a plurality of connection ears 320 corresponding to the protective covers 410 one by one, and each connection ear 320 is provided with an axle hole 321; the rear end of the protective cover 410 is provided with a connection shaft 420 which is rotatably arranged in the axle hole 321.

[0031] The mounting seat 310 is usually in a strip structure, and the connection ears 320 are arranged at equal intervals along the length direction thereof. The connection ear 320 and the connection shaft 420 at the rear end of the protective cover 410 constitute a hinge pair, which limits the rotational movement of the protective cover 410 only in the plane perpendicular to the panel of the host. This one-to-one connection structure ensures the independence of the movement of each protective cover 410.

[0032] This embodiment provides a stable rotation fulcrum and movement trajectory restriction for the protective cover 410, ensuring smooth opening and closing and accurate alignment. The independent hinge design ensures that damage or repair of a single cover will not affect the entire device, facilitating future maintenance. The fitting precision between the connecting lug 320 and the connecting shaft 420 directly affects the user experience; a good fit prevents the cover from wobbling from side to side.

[0033] As an alternative embodiment, those skilled in the art can also add high-damping grease or set damping pads at the mating point between the connecting shaft 420 and the shaft hole 321, so that the protective cover 410 has the function of hovering at any angle, preventing the cover from accidentally slipping and pinching hands under the action of gravity, and at the same time avoiding the cover shaking and affecting operation after opening. In addition, a torsion spring can also be integrated into the connecting structure to give the protective cover 410 an automatic spring-opening or closing tendency to adapt to different usage scenarios.

[0034] Alternatively, in some embodiments, such as Figures 3 to 5 As shown, the lock box 520 has a locking slot 521 adapted to the lock hook 510. The locking mechanism 530 includes a lock shaft 531 rotatably installed inside the lock box 520 and a lock cylinder 533 for driving the lock shaft 531 to rotate. The lock shaft 531 has a plurality of latches 532 that correspond one-to-one with the position of the lock hook 510. One end of the lock cylinder 533 extends to the outside of the lock box 520 and has a keyhole 534. When the protective cover 410 is in the closed state, the lock hook 510 extends into the locking slot 521. By rotating the lock cylinder 533, the lock shaft 531 is driven to rotate, which can make the latches 532 engage with the corresponding lock hooks 510 to lock or disengage to unlock.

[0035] The locking shaft 531 inside the lock box 520 serves as the main transmission shaft, running through the areas corresponding to all data interfaces 110. The latches 532 are fixed to the locking shaft 531 and rotate synchronously with it. This is a linkage control structure, where a single lock cylinder 533 controls the rotation angle of the entire locking shaft 531, thereby driving all latches 532 to simultaneously enter or exit the locking position.

[0036] This embodiment achieves unified management of multiple independent protective covers 410 through a centralized drive and multi-point execution mechanical linkage mechanism. Management personnel only need to operate one keyhole to lock all closed covers, eliminating the need to lock each interface individually, significantly improving management efficiency. Simultaneously, this mechanism allows locking operations when some covers are open and others are closed; closed covers are locked, while open covers require the key to be rotated again to lock after subsequent closure. This design simplifies maintenance processes while ensuring independent physical space isolation for each interface. As an alternative embodiment, those skilled in the art can also use a spring-loaded self-locking latch structure, combined with the cam release mechanism of the locking shaft 531, so that when the protective cover 410 is closed, the locking hook 510 directly pushes open the latch 532 and automatically engages for locking. Only when opening does it require rotating the key to drive the locking shaft 531 to open the latch 532, further simplifying the locking process and achieving convenient "close and lock simultaneously" operation.

[0037] Alternatively, in some embodiments, such as Figure 4 and Figure 5 The latch 532 shown protrudes outward along the radial direction of the locking shaft 531. The latch 532 is fixedly connected to the locking shaft 531 or integrally formed. The shape of the locking hook 510 is adapted to the latch 532.

[0038] The radially protruding design of the latch 532 is intended to increase the locking lever arm and contact area. The locking hook 510 is typically designed as an L-shaped or U-shaped structure with barbs, interlocking with the protrusion of the latch 532. One-piece molding or rigid connection ensures that the latch 532 will not slip relative to the locking shaft 531 when under load.

[0039] This embodiment enhances the locking mechanism's resistance to damage. When external force is applied to pry open the protective cover 410, the force is transmitted to the latch 532 through the hook 510. The radially protruding solid structure can withstand large shear forces and bending moments, ensuring that the locking state does not fail. This high-strength interlocking structure constitutes the last line of defense at the physical level.

[0040] Alternatively, in some embodiments, such as Figure 4 As shown, both the mounting component 300 and the lock box 520 have bolt holes 340. The mounting component 300 and the lock box 520 are fixed to the surface of the computer host 100 chassis by bolts passing through the bolt holes 340.

[0041] The bolt holes 340 are typically located inside the mounting assembly 300 and the lock box 520, or in areas covered by the protective cover 410, to increase the difficulty of disassembly. The bolts rigidly connect the device body to the computer host 100, making it part of the chassis.

[0042] This embodiment solves the problem of disassembly prevention of the protective device itself through mechanical fastening, preventing the device from being removed as a whole. Simply locking the cover is not enough; if the entire device can be easily removed, protection is meaningless. By using bolts for fixing, combined with the use of anti-theft bolts, such as internal pentagonal bolts with post or Torx bolts, physical security is further enhanced. This constructs a complete physical security boundary, making the protective device an integral part of the host chassis.

[0043] The working principle of the protection device for computer data protection in this application embodiment is as follows:

[0044] During installation, fix the mounting component 300 and the lock box 520 to the upper and lower sides of the data interface area of ​​the computer host 100 respectively, ensuring that each protective cover 410 corresponds to one data interface 110.

[0045] In normal protection mode, all protective covers 410 are in the closed position, and the lock hooks 510 are inserted into the locking slots 521 of the lock box 520. By rotating the lock cylinder 533 with the key, the lock shaft 531 is driven to rotate all the latches 532 to the locked position, hooking the lock hooks 510, thus achieving closed protection for all interfaces.

[0046] When using the interface, insert the key and rotate it in the opposite direction to unlock, then flip open the corresponding protective cover 410 and insert the peripheral data connector 200 into the data interface 110. Next, straighten the data cable 210 and pass it through the slot 411 at the front end of the protective cover 410, then close the protective cover 410 again. At this point, the data connector 200 is enclosed within the receiving cavity 412. Rotate the key again to lock, and the protective cover 410 will be locked. Because the width of the slot 411 is smaller than that of the connector 200, the connector cannot be pulled out, thus achieving anti-theft and anti-drop protection during use, while other unused interfaces remain closed and locked.

[0047] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
