Description

Technical Field

[0001] This utility model relates to the field of key replenishment device technology, specifically a portable quantum key replenishment device. Background Technology

[0002] With the rapid development of quantum communication technology, the application scenarios of quantum secure networks based on quantum key distribution are constantly expanding, and the demand for portable quantum key replenishment devices is also increasing. Since the data interface of existing quantum key replenishment devices is mostly USB interface, in actual use, the interface mismatch often occurs. At this time, it is necessary to use an adapter to convert different data interfaces.

[0003] The patent with publication number CN202221793992.4 describes a portable quantum key replenishment device. This device uses a sliding rod that slides inside a groove, causing a connecting rod to slide on one side of the storage component. The connecting rod can extend and retract inside the socket, allowing the communication data interface to be retracted into the quantum key replenishment device, thus preventing electrostatic damage to the interface. This also provides other protection for the communication data interface, extending the device's lifespan. Furthermore, a rotating rod that rotates inside a fixed block rotates the adapter and communication interface to one side of the housing. Finally, the connecting rod is used to connect and transmit data between the adapter and the communication interface. This allows for easy switching of the communication data interface based on the interface, improving usability and the practicality of the quantum key replenishment device.

[0004] The patent CN202221793992.4 includes three adapters. Although the initial intention was to adapt to the interface requirements of different devices and improve versatility, it has revealed serious problems in practical applications. The front ends of these adapters are on the same plane. When one of the adapters is used to connect to a device, the unused adapter will inevitably abut against the outer wall of the device. This not only makes the connection operation difficult, but also makes it impossible to complete the connection in some cases where the device interface is in a special position or space is limited. This greatly limits the scope of use of the device. Therefore, a portable quantum key replenishment device is proposed to address the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0030] Please see Figure 1-7 This utility model provides a technical solution:

[0031] A portable quantum key replenishment device includes a housing 1, a connection base assembly 2 fixedly connected to one side of the top of the housing 1, an end-conversion assembly 3 mounted above the connection base assembly 2, and a conversion feedback assembly 4 for cooperating with the end-conversion assembly 3 fixedly connected to the front end of the housing 1. The connection base assembly 2 includes a base 21, a reset spring 22 fixedly connected to the bottom of the inner side of the base 21, a three-segment rotating sleeve 23 fixedly connected to the top of the reset spring 22, and a triangular prism positioning shaft 24 fixedly connected to the center of the inner side of the base 21. A positioning head 25 is fixedly connected to the center of the top of the triangular prism positioning shaft 24; the end conversion assembly 3 includes a central disk 31, an adapter arm 32 is fixedly connected to the outer side of the central disk 31, a magnetic block 33 is fixedly connected to the lower surface of the adapter arm 32, an adapter port 34 is fixedly connected to the bottom end of the adapter arm 32, and port locking mechanisms 35 are fixedly connected to both sides of the rear end of the adapter port 34; a three-section rotating sleeve 23 is rotatably disposed inside the central disk 31, and the center of the inner side of the central disk 31 slides in cooperation with the outer side of the triangular prism positioning shaft 24.

[0032] As a further implementation of this solution, the port locking mechanism 35 includes a locking block 351. The back of the locking block 351 is provided with a guide groove 352 and a locking hole 353. The locking hole 353 is located at the center of the back of the locking block 351, and the guide groove 352 is located above the locking hole 353. The inner side of the guide groove 352 is connected to the inner side of the locking hole 353. This design reduces the operational error rate and enhances the stability of the connection.

[0033] As a further implementation of this solution, the conversion feedback component 4 includes a mounting bracket 41. There are two mounting brackets 41, which are fixedly installed on both sides of the front end of the inner wall of the outer casing 1. The two mounting brackets 41 are parallel to each other. A spring telescopic rod 42 is fixedly connected to the center of the front end face of the mounting bracket 41. The included angle between the spring telescopic rod 42 and the mounting bracket 41 is 90°. A feedback pin 43 is fixedly connected to the telescopic end of the spring telescopic rod 42. The surface of the feedback pin 43 is painted with red paint. The red feedback pin 43 serves as a visual feedback indicator. Its bright red color makes it easy for operators to quickly observe the conversion status of the conversion port 34 in various environments, thereby improving operational efficiency and accuracy.

[0034] As a further implementation of this solution, the adapter arm 32 is arranged in an "L" shape. The three adapter arms 32 are equidistantly arranged in a circular pattern around the central axis of the central disk 31. The magnetic block 33 is located above the outer shell 1. The magnetic block 33 and the outer shell 1 are magnetically attracted to each other. When the adapter port 34 is not adjusted, the adapter arm 32 can be firmly fixed above the outer shell 1.

[0035] As a further implementation of this solution, there is a gap between the inner side of the three-section rotating sleeve 23 and the outer side of the triangular prism positioning shaft 24. The triangular prism positioning shaft 24 and the base 21 are located on the same central axis. The three corner areas at the top of the triangular prism positioning shaft 24 are provided with circular grooves 26. During the process of the center plate 31 falling and resetting, even if there is a certain angular deviation, the positioning head 25 and the circular groove 26 can reduce the friction of the center plate 31 groove contact and guide it to return to its position smoothly. The stable tension provided by the reset spring 22 ensures that the center plate 31 can quickly and accurately return to its initial position, preparing for the next conversion of the adapter port 34.

[0036] As a further implementation of this solution, a connecting seat 5 is slidably connected to the bottom of the inner side of the outer shell 1, and a push telescopic rod 6 is fixedly connected to the rear end of the inner wall of the outer shell 1. The telescopic end of the push telescopic rod 6 is fixedly connected to the rear end of the connecting seat 5. A quantum key storage body 7 is fixedly connected to one side of the top of the connecting seat 5. A conductive plug 8 is electrically connected to the connecting end of the quantum key storage body 7. The front end of the conductive plug 8 is inserted into the rear end of the adapter port 34. An operating handle 9 is fixedly connected to the middle of the top of the connecting seat 5. The operating handle 9 is slidably connected to the outer shell 1. Sloping grooves 10 are provided in both corner areas of the front end of the outer shell 1. The sloping grooves 10 can prevent the outer shell 1 from interfering with the conversion operation of the adapter port 34.

[0037] Workflow: When the adapter port 34 in the adapter assembly 3 needs to be changed, the operator pulls the center plate 31 upwards. As the center plate 31 moves, it simultaneously moves the three equidistant adapter arms 32 and the adapter port 34 in the horizontal direction. When the center plate 31 moves above the triangular prism positioning shaft 24, the adapter port 34 to be transferred is rotated to the front of the housing 1 via the center plate 31. Then, the center plate 31 is released. Because the triangular prism positioning shaft 24 is triangular in shape, it ensures precise positioning of the center plate 31 with each rotation. The positioning head 25 has a spherical structure, and the three corner areas of the top of the triangular prism positioning shaft 24 are all provided with circular grooves 26. This allows the spherical positioning head 25 and the circular grooves 26 to reduce the error rate of the center disk 31 during its downward movement when the center disk 31 falls, enabling the center disk 31 to be accurately reset to the appropriate position of the triangular prism positioning shaft 24. During this process, the reset spring 22 provides a three-section rotating sleeve 23 to provide stable tension for the reset of the center disk 31. As the adapter arm 32 drives the adapter port 34 to move downward, the adapter port 34... The port locking mechanism 35 will fully contact the conversion feedback component 4. The telescopic end of the spring telescopic rod 42 is responsible for providing elastic force to the feedback pin 43. After it moves to the appropriate position, the feedback pin 43 will be embedded in the guide groove 352 of the locking block 351 under the action of the spring telescopic rod 42. The guide groove 352 is responsible for providing a moving connection for the feedback pin 43. The operator can observe the exposure of the red feedback pin 43 through the locking hole 353 to obtain feedback information that the port conversion port 34 has been successfully converted, thus confirming that the conversion port 34 has been successfully converted. The operator releases the operating handle 9. At this time, pushing the telescopic rod 6 will push the connecting seat 5 forward. The quantum key storage body 7, which is fixedly connected to one side of the top of the connecting seat 5, and the conductive plug 8, which is electrically connected to its connecting end, will be inserted into the rear end of the target conversion port 34 as the connecting seat 5 moves forward. Because the rear end of the conversion port 34 and the front end of the conductive plug 8 are plugged in, the connection between the adapter and the internal circuit is completed, realizing the connection conversion operation of the entire portable quantum key replenishment device, so as to adapt to the interface requirements of different devices.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
