Description

Technical Field

[0001] The invention relates to the technical field of information security equipment, and in particular to a magnetic repulsion unlocking USB port lock and a USB port. Background Art

[0002] The USB port is an interface for information exchange between computers and external devices, through which files in the computer memory can be accessed, modified, and copied. The use of existing USB ports has the following problems: First, the USB interfaces of existing computers are exposed when they leave the factory, and external devices can be connected to the computer at will, which poses a risk of leakage of important data; second, in industries involving network information security, such as substations and power grid intranet environments, once viruses or criminals invade the intranet environment, it will threaten production safety and even cause power grid accidents, posing a greater information security risk; third, the existing USB port locks have simple structures and are mostly non-detachable and cannot be reused. After locking, if they need to be used, they need to be removed violently, which can easily damage the USB port; fourth, the existing USB port locks have complex structures. Although they can be disassembled, they are large in size and expensive in cost. After locking, the protruding part of the lock is long and can easily break under external force. In summary, the existing USB ports and USB locks are not conducive to the encryption and unlocking of USB ports, and are not conducive to the information security management of special industries. Summary of the invention

[0003] In order to solve the above problems, the present invention aims to provide a magnetic repulsion unlocking USB port lock and a USB port, which are locked by the port lock and the USB port, and unlocked by an unlocking key, which is convenient, practical, safe, fast and reusable.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A magnetic repulsion unlocking USB port lock comprises a magnetic key, a metal shell and a structural cavity located in the metal shell, wherein a locking device is arranged in the structural cavity, one end of the locking device is movably connected to one end of the structural cavity through a first spring, a first permanent magnet is fixed to the other end of the locking device, a locking port and an unlocking port cooperating with the locking device are arranged on the upper part of the structural cavity, and the magnetic key generates a same-sex repulsive force by cooperating closely with the first permanent magnet to drive the locking device from the locking port to the unlocking port for unlocking the USB port.

[0006] Furthermore, the locking device includes a hollow slider, a second spring and a locking wedge. The hollow slider is provided with a space allowing the second spring and the locking wedge to move freely up and down, and the locking wedge is connected to the bottom of the hollow slider through the second spring. When the locking device reaches the locking port, the locking wedge protrudes out of the locking port, and when the locking device reaches the unlocking port, the locking wedge is limited and flush with the unlocking port.

[0007] Furthermore, it also includes a fixing buckle, which is fixed on the locking wedge to limit the locking wedge to prevent it from turning over.

[0008] Furthermore, a limiting opening is provided on the upper portion of the hollow sliding block to allow the locking wedge to move up and down a certain distance, and the fixing buckle is larger than the limiting opening to prevent the locking wedge from falling off and turning over.

[0009] Furthermore, arc surfaces are provided on the opposite sides of the locking opening and the inclined surface of the locking wedge to facilitate the descending and recovery of the locking wedge during the unlocking process.

[0010] Furthermore, when the locking device reaches the locking opening or the unlocking opening, the first spring and the second spring are both in a compressed state.

[0011] Furthermore, the metal shell is a ferromagnetic metal shell used to generate attraction with the first permanent magnet and the magnetic key.

[0012] Furthermore, the magnetic key includes a key ring and a second permanent magnet with a switchable magnetic direction fixed on the key ring.

[0013] In order to achieve the above object, the present invention further provides a USB port, which cooperates with the above magnetic repulsion unlocking USB port lock.

[0014] Furthermore, the USB port includes a USB shell and a plastic platform inside the USB port for placing and fixing a USB power supply and a serial port. The USB shell is provided with at least one locking port, and the locking port cooperates with a locking wedge for locking. The plug-in interface between the plastic platform and the USB port corresponds to and matches the magnetic repulsion unlocking USB port lock; when the magnetic repulsion unlocking USB port lock is inserted into the plug-in interface, the surface of the magnetic repulsion unlocking USB port lock is recessed in the outer surface of the USB port.

[0015] Beneficial effects: The present invention solves the problem that the USB port of the computer in the "intranet environment" of the substation is exposed, important data is easily leaked, viruses or criminals are easy to invade the intranet environment, and "illegal external connection" information is illegal. After the USB is locked, the surface of the present invention is sunken into the surface of the computer, so that it cannot be forcibly unlocked by external force when it is locked without destroying the normal information interaction function of the USB. When the USB interaction function needs to be restarted, the present invention can be easily unlocked with a special key without violent disassembly, and the lock can still be reused after unlocking. The present invention is small in size and simple in structure and production process, and therefore has a high value of promotion and utilization. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0023] Example 1

[0024] See also Figure 1-4 A magnetic repulsion unlocking USB port lock, comprising a magnetic key 3, a metal shell 1 and a structural cavity 2 located in the metal shell 1, wherein a locking device is provided in the structural cavity 2, one end of the locking device is movably connected to one end in the structural cavity 2 through a first spring 4, and a first permanent magnet 5 is fixed to the other end of the locking device, and a lock port 20 and an unlocking port 21 cooperating with the locking device are provided on the upper part of the structural cavity 2, wherein the magnetic key 3 generates a same-sex repulsive force by cooperating closely with the first permanent magnet 5 to drive the locking device from the lock port 20 to the unlocking port 21 for unlocking the USB port.

[0025] The port lock of this embodiment can complete the USB security locking process by extending it into the USB port. By utilizing the principle of mutual repulsion between like magnets, the magnetic key of this embodiment drives the first permanent magnet on the locking device through magnetic force to reach the unlocking port to complete the unlocking of the USB port. This is convenient, fast and reusable.

[0026] In a specific example, the locking device includes a hollow slider 6, a second spring 7, and a locking wedge 8. A space is provided in the hollow slider 6 to allow the second spring 7 and the locking wedge 8 to move freely up and down. The locking wedge 8 is connected to the bottom of the hollow slider 6 through the second spring 7. When the locking device reaches the locking port 20, the locking wedge 8 protrudes out of the locking port 20. When the locking device reaches the unlocking port 21, the locking wedge 8 is limited and flush with the unlocking port 21.

[0027] The locking device of this embodiment is reasonably and cleverly designed. The locking wedge can move up and down and left and right through the cooperation of the second spring and the hollow slider, thereby completing the locking and unlocking of the USB port.

[0028] In a specific example, it also includes a fixing buckle 9, which is fixed on the locking wedge 8 to limit the locking wedge 8 to prevent it from flipping over. The upper part of the hollow slider 6 is provided with a limiting opening that allows the locking wedge 8 to move up and down a certain distance. The fixing buckle 9 is larger than the limiting opening and is used to prevent the locking wedge 8 from falling off and flipping over.

[0029] It should be noted that a limit opening is provided on the upper part of the hollow slider of the present embodiment for allowing the locking wedge to move up and down a certain distance. In order to prevent the locking wedge from flipping over during the movement of the hollow slider, the locking stability of the locking wedge is achieved by cooperating with the fixed buckle and the limit opening. In addition, the port lock of the present embodiment, when not unlocked, can also better lock the USB interface when pulled out by external force to prevent flipping and causing the port lock to be pulled out.

[0030] In a specific example, an arc surface is provided on the opposite side of the locking opening 21 and the inclined surface of the locking wedge 8 to facilitate the descending and recovery of the locking wedge 8 during the unlocking process.

[0031] The arc surface of this embodiment reduces the contact friction force of the locking wedge 8 during the unlocking process, thereby better unlocking the USB port.

[0032] In a specific example, when the locking device reaches the locking port 20 or the unlocking port 21 , the first spring 4 and the second spring 7 are both in a compressed state.

[0033] During the locking and unlocking processes of this embodiment, the first spring and the second spring are both in a compressed state, which increases the pressing force between the vertical surface of the locking wedge and the locking and unlocking openings, thereby making the locking and unlocking states of the port lock of this embodiment more stable and firm.

[0034] In a specific example, the metal shell 1 is a ferromagnetic metal shell for generating attraction with the first permanent magnet 5 and the magnetic key 3 .

[0035] The ferromagnetic metal shell of this embodiment generates an attractive force with the first permanent magnet, and works together with the spring to further strengthen the locking force of the locking device; in addition, after using the magnetic key to unlock, the direction of the magnetic key is changed to pull the port lock out through the ferromagnetic metal shell and the attractive magnetic force of the first permanent magnet, thereby unlocking the USB port.

[0036] In a specific example, the magnetic key 3 includes a key ring 30 and a second permanent magnet 31 fixed on the key ring 30 and capable of switching magnetic directions.

[0037] The magnetic key of this embodiment can change the magnetic direction through the second permanent magnet, thereby generating repulsive force and attractive force.

[0038] Example 2

[0039] See also Figure 1 , Figure 4 : This embodiment also discloses a USB port, which cooperates with the above-mentioned magnetic repulsion unlocking USB port lock.

[0040] In a specific example, the USB port includes a USB shell 10 and a plastic platform 11 in the USB port for placing and fixing a USB power source and a serial port. The USB shell 10 is provided with at least one locking port 100, and the locking port 100 cooperates with a locking wedge 8 for locking. The plug-in port 12 between the plastic platform 11 and the USB port corresponds to and matches the magnetic repulsion unlocking USB port lock; when the magnetic repulsion unlocking USB port lock is inserted into the plug-in port 12, the surface of the magnetic repulsion unlocking USB port lock is recessed from the outer surface of the USB port.

[0041] The surface of the port lock of the present embodiment is recessed in the outer plane of the computer's USB port, so that it is not easy to forcefully unlock the port lock by external force when the port lock is in the locked state. In addition, the USB port of the present embodiment can be provided with a plurality of locking openings, preferably two, so the corresponding USB port lock can also be provided with two locking wedges used in conjunction with each other to improve the locking stability.

[0042] In a specific implementation, the locking process is as follows: the USB port lock is directly inserted into the USB port of the computer, and the locking wedge is then stuck in the locking port of the USB port under the action of the second spring. Figure 3 As shown. The port lock surface is recessed into the outer surface of the computer USB port, and the USB is locked;

[0043] Unlocking process: stick the magnetic key to the outer surface of the port lock. The like magnetic poles repel each other, and the thrust generated is greater than the thrust of the spring. The hollow slider moves to the right under the push of the magnetic force and finally gets stuck at the unlocking port (such as Figure 4As shown), the magnetic key converts the magnetic direction to be attracted to the ferromagnetic housing and generates attraction with the first permanent magnet, so as to pull out the USB port lock and unlock it;

[0044] Port lock reset: Use a sharp object to press the unlocking port. Under the push of the first spring and the pull of the first permanent magnet, the port lock is released. Figure 4 Return to Figure 3 state.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
