Description

Technical Field

[0001] This utility model relates to the field of USB interface security technology, and more specifically, to a physical locking device for the USB interface of an office computer. Background Technology

[0002] With the rapid development of information technology, data breaches occur frequently. USB interfaces, as a common interface for connecting computers and other devices to external devices, are often used for data transmission and have become one of the important channels for information leakage. In some specific places, such as corporate offices, school computer rooms, and government agencies, strict management of device use is required. In order to prevent employees or students from using USB interfaces to connect external devices at will and to avoid equipment failure, system crashes, and other problems caused by the use of unauthorized devices, USB interface locking devices have emerged. However, traditional locking devices without a recovery design cannot automatically rebound to expose the interface at the moment of unlocking after the interface locking device is unlocked. Instead, the cover will fall onto the interface surface, and the user needs to flip it upwards to insert the cable or USB flash drive into the USB interface.

[0003] A search revealed that publication number CN114741340A discloses a USB interface isolation device, relating to the field of USB interface security technology. It includes a housing, a USB plug and a USB interface mounted on the housing, with the USB plug connected to a USB connector. It also includes a controller, a gating circuit, a locking mechanism, and an identification / unlocking device mounted on the housing. The gating circuit is electrically connected between the USB plug and the USB interface. The controller's control terminal is electrically connected to the control terminal of the gating circuit and controls the gating circuit to turn on or off, causing the USB plug and USB interface to connect or disconnect accordingly. The identification / unlocking device is electrically connected to and communicates with the controller. Through the housing, the USB plug on the housing, the USB interface, the controller, the gating circuit, the locking mechanism, and the identification / unlocking device, it achieves good USB interface security. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] The existing locking device without a flip cover restoration design is in a partially closed state after the user opens it. In addition, the locking device is designed to be relatively narrow because it needs to be installed on the side of the narrow computer. When opening it, the user can only flip the upper cover upward with their fingernail through the gap between the upper and lower flip cover slots to expose the computer's USB port.

[0005] Therefore, a physical locking device for the USB interface of office computers is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a physical locking device for the USB interface of an office computer to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a physical locking device for a USB interface of an office computer, comprising a recovery component, a connecting component, a locking mechanism, and a housing component. The recovery component is mounted on the side of the housing component, and the connecting component is mounted on the inner diameter surface of the recovery component. The locking mechanism is mounted on the upper part of the inner wall of the housing component.

[0008] Preferably, the recovery component includes a first lotus leaf, a second lotus leaf, and a torque spring, with the second lotus leaf placed below the first lotus leaf and the torque spring placed on the side of the second lotus leaf.

[0009] Preferably, the connecting assembly includes a threaded rod, a nut, and a locking washer, wherein the nut is mounted on the outer diameter surface of the threaded rod, and the locking washer is placed on the side of the nut.

[0010] Preferably, the locking mechanism includes a fixing component, a lock cylinder component, and a locking pin component, wherein the lock cylinder component is mounted on the side of the fixing component, and the locking pin component is placed on the side of the lock cylinder component away from the fixing component.

[0011] Preferably, the fixing component includes a latch, a first connecting plate, a second connecting plate, and a first restoring spring. The first connecting plate is installed on the side of the latch, and the second connecting plate is installed on the side of the first connecting plate away from the latch. The first restoring spring is placed below the first connecting plate.

[0012] Preferably, the lock cylinder assembly includes a lock cylinder post, a key slot and a first lock post, and the lock cylinder post has a key slot carved into its side wall, and the first lock post is placed on the side of the key slot.

[0013] Preferably, the locking post assembly includes a second locking post, a second restoring spring, and a fixing post, wherein the second restoring spring is installed on the side of the second locking post, and the fixing post is installed on the side of the second restoring spring away from the second locking post.

[0014] Preferably, the housing assembly includes an upper flip cover, a lower flip-out slot, and a lock hole, with the lower flip-out slot placed below the upper flip cover and the lock hole being formed in the side wall of the lower flip-out slot.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with existing technologies, this physical locking device for the USB interface of office computers uses a recovery component. When the user opens the locking device, the recovery component can quickly separate the upper cover and the lower slot of the shell component. After the upper cover of the shell component is opened, it will rebound upward under the action of the torque spring of the recovery component, so that the interface is directly exposed, without the need for the user to separate the shell component from both sides.

[0017] 2. Compared with existing technologies, this physical locking device for the USB interface of an office computer locks the upper cover and lower slot of the outer shell assembly through a locking mechanism. Without a key matching the key slot in the lock cylinder, the outer shell assembly cannot be opened by itself, thus ensuring the security of the locking mechanism. When the user needs to use the interface, they need to insert a key matching the locking mechanism into the key slot of the lock cylinder. At this time, the first locking pin of the lock cylinder assembly will change its position in the lock cylinder due to the groove on the key, thereby pushing the locking pin assembly to lock the second locking pin of the lock cylinder assembly and retracting it from the lock cylinder assembly. When the locking pin assembly retracts the locked second locking pin, the key can be turned normally. When the user turns the key, the lock cylinder assembly rotates, and the lock cylinder will pull the first connecting plate of the fixing assembly to rotate with the lock cylinder assembly. When the first connecting plate rotates, it will cause one side of the second connecting plate to swing, while the other side will cause the bolt to move horizontally, causing the bolt to be pulled out of the keyhole, thus separating the upper cover and lower slot of the outer shell assembly.

[0025] As attached Figures 1 to 4 The physical locking device for the USB interface of the office computer shown includes a restoration component 1, a connecting component 2, a locking mechanism 3, and a housing component 4. The restoration component 1 is installed on the side of the housing component 4, the connecting component 2 is installed on the inner diameter surface of the restoration component 1, and the locking mechanism 3 is installed on the upper inner wall of the housing component 4.

[0026] Specifically: When users have urgent business to attend to and the files on their office computers are confidential, they can use the material locking device to lock the interface on the surface of the office computer. Before using the locking device, users need to install the locking device on the surface of the computer interface. When using the locking device, the user needs to close the housing assembly 4. During the closing process, the housing assembly 4 will rotate 90 degrees around the connecting assembly 2. When the housing assembly 4 is closed, the locking mechanism 3 will be inserted into the housing assembly 4 to protect the computer interface. When the user needs to use the interface, they need to use the key that matches the locking mechanism 3 to open the housing assembly by turning it. The housing assembly will then rebound upwards under the action of the restoring assembly 1, directly exposing the interface without the user needing to separate the two sides of the housing assembly.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, the recovery component 1 includes a first lotus leaf 5, a second lotus leaf 6, and a torque spring 7. The second lotus leaf 6 is placed below the first lotus leaf 5, and the torque spring 7 is placed on the side of the second lotus leaf 6. When the user opens the outer shell assembly, the torque spring 7 of the recovery component 1 will quickly spring the outer shell assembly open through elastic force. The recovery component 1 connects the upper and lower sides of the outer shell assembly through the first lotus leaf 5 and the second lotus leaf 6.

[0030] In a preferred embodiment, the connecting assembly 2 includes a threaded rod 8, a nut 9, and a locking washer 10. The nut 9 is mounted on the outer diameter surface of the threaded rod 8, and the locking washer 10 is placed on the side of the nut 9. When the user needs to disassemble the resetting assembly 1, he / she needs to use a small screwdriver to turn the nut 9 so that it rotates on the outer diameter surface of the threaded rod 8 and moves to the side closest to the threaded rod 8. After the nut 9 is unscrewed, the user only needs to remove the locking washer 10 and the nut 9 together to separate the resetting assembly 1.

[0031] In a preferred embodiment, the locking mechanism 3 includes a fixing component 11, a lock cylinder component 12, and a locking pin component 13. The lock cylinder component 12 is mounted on the side of the fixing component 11, and the connection between the fixing component 11 and the lock cylinder component 12 is a hinge connection. The locking pin component 13 is placed on the side of the lock cylinder component 12 away from the fixing component 11. When the user needs to open the locking mechanism 3 with a key, the user needs to insert the key into the lock cylinder component 12, causing the part of the locking pin component 13 inserted into the lock cylinder component 12 to be pulled out. Then, by turning the key, the lock cylinder component 12 is rotated. During the rotation of the lock cylinder component 12, the locking pin component 13 is pulled to move horizontally, thereby allowing the outer shell component to be opened.

[0032] In a preferred embodiment, the fixing assembly 11 includes a latch 14, a first connecting plate 15, a second connecting plate 16, and a first restoring spring 17. The first connecting plate 15 is mounted on the side of the latch 14, and the second connecting plate 16 is mounted on the side of the first connecting plate 15 away from the latch 14. The latch 14 and the first connecting plate 15 are hinged together, and the second connecting plate 16 and the first connecting plate 15 are also hinged together. The first restoring spring 17 is placed below the second connecting plate 16 and the first connecting plate 15. The second connecting plate 16 and the lock cylinder assembly 12 are hinged together. When the user turns the lock cylinder assembly 12 with the key, the first connecting plate 15 of the fixing assembly 11 will rotate with the lock cylinder assembly 12. When the first connecting plate 15 rotates, it will cause one side of the second connecting plate 16 to swing, and the other side will cause the bolt 14 to move horizontally. When the user pulls the key out of the lock cylinder assembly 12, the bolt 14 will be pushed out of the outer shell assembly again by the first return spring 17. At this time, the bolt 14 will pull the lock cylinder assembly 12 back to its original position through the first connecting plate 15 and the second connecting plate 16.

[0033] In a preferred embodiment, the lock cylinder assembly 12 includes a lock cylinder pin 18, a key slot 19, and a first lock pin 20. The key slot 19 is carved into the side wall of the lock cylinder pin 18, and the first lock pin 20 is placed on the side of the key slot 19. When the user inserts the key into the key slot 19 of the lock cylinder pin 18, the first lock pin 20 will change its position in the lock cylinder pin 18 due to the groove on the key, thereby pushing the locking pin assembly 13 to lock the part of the lock cylinder assembly 12 and retract it from the lock cylinder assembly 12. When the locking pin assembly 13 retracts the locked part, the key can be turned normally.

[0034] In a preferred embodiment, the locking post assembly 13 includes a second locking post 21, a second restoring spring 22, and a fixing post 23. The second restoring spring 22 is mounted on the side of the second locking post 21. The second locking post 21 and the second restoring spring 22 are interference-fitted. The second restoring spring 22 and the fixing post 23 are also interference-fitted. The fixing post 23 is mounted on the side of the second restoring spring 22 away from the second locking post 21. When the user inserts the key into the lock cylinder assembly 12, the second locking post 21 of the locking post assembly 13 will be pressed back into the locking post assembly 13 from the lock cylinder assembly 12. When the user pulls out the key, the second restoring spring 22 will push the second locking post 21 back into the lock cylinder assembly 12. The fixing post 23 can fix the second restoring spring 22.

[0035] In a preferred embodiment, the housing assembly 4 includes an upper flip cover 24, a lower flip groove 25, and a lock hole 26. The lower flip groove 25 is placed below the upper flip cover 24, and the lock hole 26 is carved into the side wall of the lower flip groove 25. When the user uses a key to open the locking mechanism 3, the latch 14 will be pulled out from the lock hole 26, thereby separating the upper flip cover 24 and the lower flip groove 25 of the housing assembly.

[0036] The working process of this utility model is as follows: First, when the user has an urgent matter to handle and the files on the office computer are confidential, they can use the material locking device to lock the interface on the surface of the office computer. Before using the locking device, the user needs to install the locking device on the surface of the computer interface in advance. When using the locking device, the user needs to close the housing assembly 4. During the closing process of the housing assembly 4, the housing assembly 4 will rotate 90 degrees around the connecting assembly 2. When the housing assembly 4 is closed, the locking tongue 14 of the fixing assembly 11 will be inserted into the housing assembly 4 to protect the computer interface. When the user needs to use the interface, they need to insert the key matching the locking mechanism 3 into the key slot 19 of the lock cylinder 18. At this time, the first locking pin 20 of the lock cylinder assembly 12 will change its position in the lock cylinder pin 18 due to the groove on the key, thereby pushing the locking pin assembly 13 to lock the second locking pin 21 of the lock cylinder assembly 12 and retracting from the lock cylinder assembly 12. When the locking pin assembly 13 retracts the locked second locking pin 21, the key can be turned normally. When the user turns the key to make the lock cylinder assembly 12 rotate, the lock cylinder pin 18 will pull the first connecting plate 15 of the fixing assembly 11 to rotate with the lock cylinder assembly 12. When the first connecting plate 15 rotates, it will cause one side of the second connecting plate 16 to swing, and the other side will cause the bolt 14 to move horizontally, so that the bolt 14 is pulled out of the key hole 26, thereby separating the upper flip cover 24 and the lower flip groove block 25 of the outer shell assembly.

[0037] When the user removes the key from the lock cylinder assembly 12, the bolt 14 will emerge from the outer shell assembly again under the push of the first return spring 17. At this time, the bolt 14 will pull the lock cylinder post 18 of the lock cylinder assembly 12 back to its original position through the first connecting plate 15 and the second connecting plate 16. When the lock cylinder post 18 returns to its original position, the second return spring 22 fixed above the fixing post 23 will push the second locking post 21 back into the lock cylinder post 18, thereby relocking the lock cylinder assembly 12. The upper flip cover 24 of the outer shell assembly and the first leaf 5 of the return assembly 1 are connected by bolts, and the lower flip groove block 25 and the second leaf 6 are connected by bolts. Therefore, when the upper flip cover 24 of the outer shell assembly is opened, it will rebound upward under the action of the torque spring 7 of the return assembly 1, so that the interface is directly exposed, without the need for the user to separate the two sides of the outer shell assembly.

[0038] When the locking mechanism 3 of the outer casing assembly is damaged, or when it is difficult to unlock due to lack of internal lubrication, the user needs to disassemble the upper cover 24 from the locking device and then carefully inspect the internal locking mechanism 3. During the process of removing the upper cover 24, a small screwdriver is needed to turn the nut 9, causing it to rotate on the outer diameter surface of the threaded rod 8 and move to the side closest to the threaded rod 8. After the nut 9 is unscrewed, the user only needs to remove the anti-loosening washer 10 and the nut 9 together to separate the upper cover 24 from the locking device. The above is the working principle of the physical locking device of the USB interface of the office computer.
