DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1:

[0042] The present invention discloses a USB hub for docking multiple certificate interfaces, comprising a storage portion and a docking portion. The storage portion is used to store several groups of USB certificates or U disks. It should be noted that when an enterprise handles various businesses, it will use USB certificates from different banks. The storage portion can store USB certificates from different banks together to prevent the USB certificates from being lost and facilitate the management of USB certificates. The storage portion can be a box or a bag. For example, when it is a bag, a cushion pad is filled inside the bag, and the cushion pad is set as a sponge pad, which is fixed on the inner wall of the box or the bag. A sealing tape is set at the opening of the bag, such as Figure 13 and Figure 14As shown in the figure, an automatic air extraction mechanism 3 is provided on the bag. The automatic air extraction mechanism 3 includes a cylinder 31. End caps 33 are slidably connected to both ends of the cylinder 31. A first one-way valve 32 is installed at the middle position on the side of the cylinder 31. The first one-way valve 32 conveys the air in the bag into the cylinder 31. A second one-way valve 34 is installed on the end cap 33. The second one-way valve 34 conveys the air in the cylinder 31 into the external environment. A spring is provided between the two end caps 33. When in use, the end caps 33 at both ends of the cylinder 31 are pressed simultaneously. The end caps 33 can squeeze the air in the cylinder 31, so that the air in the cylinder 31 is discharged to the external environment through the second one-way valve 34. When the end caps 33 at both ends of the cylinder 31 are released, the spring acts on the inner side surface of the end cap 33, pushing the end cap 33, so that the two end caps 33 move towards both ends of the cylinder 31 respectively. During this process, a negative pressure is formed in the inner cavity of the cylinder 31, and the air in the bag can enter the cylinder 31 through the first one-way valve 32. Then, the end caps 33 at both ends of the cylinder 31 are pressed again, and after repeating several times, the air pressure in the bag can be reduced, so that the bag is closely attached to the USB certificate, realizing the fixation of the position of the USB certificate, preventing the USB certificate from loosening, ensuring good connection between the USB certificate and the docking part, and not easy to loosen. The automatic air extraction mechanism 3 can also be replaced by an air extraction valve. The user can extract the air in the bag from the air extraction valve through a syringe, reducing the air pressure in the bag, and centrally storing the USB certificates of different banks together; The docking part is used to control the connection method between several groups of USB certificates or USB flash drives and the PC terminal, that is, the storage part is connected to the PC terminal through the docking part, usually using a USB port. The storage part can establish a data connection with the USB port on the PC terminal through the docking part. The connection methods include establishing a data link and disconnecting the data link;

[0043] The docking part can be connected to several groups of USB certificates or USB flash drives stored inside the storage part respectively using cables. For different USB certificates or USB flash drives on the docking part, corresponding switches are installed. When in use, the corresponding switch of the USB certificate or USB flash drive can be turned on, so that the USB certificate or USB flash drive will establish a data link with the PC terminal through the docking part, and the staff can perform corresponding operations on the USB certificate or USB flash drive. When it is necessary to replace the USB certificate or USB flash drive, turn off the current switch and turn on the switch corresponding to the USB certificate or USB flash drive to be replaced, so that the non-plugging and unplugging replacement of the USB certificate or USB flash drive is realized, reducing the plugging and unplugging frequency between the USB certificate or USB flash drive and the PC terminal, protecting the connection ports between the USB certificate or USB flash drive and the PC terminal. In addition, it should be noted that the storage part can protect the USB certificate or USB flash drive, ensuring that the USB certificate or USB flash drive will not be subject to external mechanical collisions, improving the security of the USB certificate or USB flash drive.

[0044] Embodiment 2:

[0045] AsFigures 1-5 As shown, the difference from the embodiment 1 is that the storage box adopts the arrangement of a box body 1 and a box cover 2, the box body 1 is provided with a main storage slot 11, and the box cover 2 is provided with a secondary storage slot 21, and both the main storage slot 11 and the secondary storage slot 21 are used to store USB certificates or U disks;

[0046] It should be noted that the box body 1 and the box cover 2 cooperate with each other to realize the storage of multiple USB certificates or U disks, and the stored USB certificates or U disks are protected, and the main storage slot 11 and the auxiliary storage slot 21 respectively opened on the box body 1 and the box cover 2 can be used to place USB certificates or U disks respectively, so that when in use, after the box cover 2 is opened, the USB certificates or U disks will be neatly distributed in the main storage slot 11 and the auxiliary storage slot 21, which is convenient for the staff to use different USB certificates or U disks, and a corrugated spacer can be set inside the main storage slot 11 to fix the inserted USB certificate or U disk.

[0047] like Figures 1-5 As shown, the docking portion includes a line collection port 12 and an external line 16. When in use, the external line 16 is directly connected to the PC terminal. The number of the line collection port 12 is set to be several. Figure 1 and Figure 2 For example, the number of the USB ports is seven, so that the box body 1 and the box cover 2 can store seven different USB certificates or U disks at the same time. The line collection port 12 is arranged in the main storage slot 11, and is used to connect the USB certificate or U disk. The external line 16 is arranged at one end of the box body 1, and is used to connect the PC terminal to realize the data connection between the USB certificate or U disk and the PC terminal. The output end of the external line 16 can adopt a USB interface or a type-C interface or other commonly used interfaces. The external line 16 can also adopt one or a combination of any of them. A control button 13 is arranged on the top surface of the box body 1, and the line collection port 12 is connected to the external line 16 through the control button 13;

[0048] It should be noted that after the USB certificate or U disk is connected to the hub port 12, it can be connected to the external line 16 through the control button 13, and the external line 16 is directly connected to the PC terminal, so the USB certificate or U disk can be connected to the PC terminal. When in use, the control button 13 corresponding to the USB certificate or U disk can be turned on, so that the USB certificate or U disk will be connected to the PC terminal through the hub port 12 and the external line 16. When the staff needs to switch the USB certificate or U disk, they only need to turn on the control button 13 corresponding to the USB certificate or U disk, so that the switching of the USB certificate or U disk is realized, which is very convenient for the staff's daily work.

[0049] Embodiment 3:

[0050] like Figure 1 ,Figure 7 and Figure 8 As shown, a physical partition mechanism 14 is provided on one side of the top surface of the box body 1. Before using the USB certificate or U disk inside the box body 1 and the box cover 2, the physical partition mechanism 14 can physically isolate the connection between the USB certificate or U disk and the external line 16. In this way, when an unauthorized person uses the USB certificate or U disk inside the box body 1 and the box cover 2, even if the unauthorized person connects the external line 16 to the PC terminal, the PC terminal cannot read the USB certificate or U disk inside the box body 1 and the box cover 2 through the external line 16, so that the security of the USB certificate or U disk inside the box body 1 and the box cover 2 can be ensured; the physical partition mechanism 14 includes a driver 141, the output end of the driver 141 is connected to a movable terminal 143, and a movable slot 142 matching the movable terminal 143 is provided on the top surface of the box body 1 near the movable terminal 143. Figure 7 and Figure 8 The mobile slot 142 in the embodiment is open. In actual operation, a sealing cover needs to be provided on the top surface of the mobile slot 142 to seal the top surface of the mobile slot 142, so that a sealed cavity can be formed on one side of the mobile terminal 143. The driver 141 can drive the mobile terminal 143 to make the mobile terminal 143 slide freely in the mobile slot 142. One end of the mobile terminal 143 is connected to the line collection port 12, so that the USB certificate or U disk connected to the line collection port 12 is connected to the mobile terminal 143. The side wall of the mobile slot 142 is provided with a docking port matching the mobile terminal 143, and the docking port is connected to the control button 13. When the mobile terminal 143 is out of contact with the docking port, the USB certificate or U disk is physically separated from the control button 13. When the mobile terminal 143 is in contact with the docking port, the USB certificate or U disk is connected to the control button 13.

[0051] When the physical partition mechanism 14 is used, if the authorized personnel first connect the external line 16 to the PC terminal, and then turn on the driver 141. The output end of the driver 141 will drive the movable terminal 143, so that the movable terminal 143 can slide freely in the movable slot 142 and finally connect to the docking port. In this way, the USB certificate or U disk will establish a connection with the control button 13 through the movable terminal 143, and the control button 13 is directly connected to the external line 16, and the external line 16 is connected to the PC terminal, so that the USB certificate or U disk is connected to the PC terminal. The authorized personnel can use the PC terminal and the USB certificate or U disk to complete the company's tasks;

[0052] If it is an unauthorized person, the unauthorized person will use the USB certificate or USB flash drive inside the box body 1 and the box cover 2. However, since the drive 141 cannot be normally opened at this time, the USB certificate or USB flash drive and the control button 13 will be physically separated, and the PC terminal cannot read the USB certificate or USB flash drive inside the box body 1 and the box cover 2 through the external line 16, which can ensure the security of the USB certificate or USB flash drive inside the box body 1 and the box cover 2.

[0053] As Figure 6 and Figure 7 shown, a safety lock card 15 is fixed at the middle position of the top surface of the box body 1, and a pneumatic lock 23 is fixedly connected to the bottom surface of the box cover 2 near the safety lock card 15. A safety lock tongue 231 matching the safety lock card 15 is inserted into the pneumatic lock 23.

[0054] It should be noted that since the safety lock tongue 231 matching the safety lock card 15 is inserted into the pneumatic lock 23, when the box body 1 and the box cover 2 are closed, the safety lock tongue 231 can extend out of the pneumatic lock 23 and be stuck in the safety lock card 15, thus realizing the locking of the box body 1 and the box cover 2 and ensuring that the box body 1 and the box cover 2 can safely protect the USB certificate or USB flash drive.

[0055] As Figure 9 shown, a lock tongue groove 233 matching the safety lock tongue 231 is provided in the inner cavity of the pneumatic lock 23. The side of the moving terminal 143 away from the docking port is a sealed cavity. The lock tongue groove 233 is hermetically connected to the sealed cavity through a channel. When the moving terminal 143 moves, the moving terminal 143 is used to adjust the air pressure in the lock tongue groove 233.

[0056] It should be noted that a second docking hole 232 is provided on the bottom surface of the box cover 2, and the second docking hole 232 communicates with the lock tongue groove 233. A first docking hole 144 is provided on the top surface of the box body 1 corresponding to the position of the second docking hole 232, and the first docking hole 144 communicates with the sealing cavity. When the box body 1 and the box cover 2 are closed, the first docking hole 144 and the second docking hole 232 will just be docked, or the first docking hole 144 and the second docking hole 232 are directly connected by an air pipe to ensure the sealing between the lock tongue groove 233 and the sealing cavity. In this way, the lock tongue groove 233 can be connected to the sealing cavity. When the moving terminal 143 moves towards the docking port end, the moving terminal 143 will increase the volume of the sealing cavity and reduce the air pressure in the sealing cavity. Since the lock tongue groove 233 is connected to the sealing cavity, the air in the lock tongue groove 233 can enter the sealing cavity to balance the air pressure. When the air pressure in the lock tongue groove 233 decreases, the air pressure outside the safety lock tongue 231 will be greater than the internal air pressure. In this way, the safety lock tongue 231 will retract into the lock tongue groove 233 under the action of the air pressure difference and disengage from the safety lock catch 15, that is, the automatic unlocking of the box body 1 and the box cover 2 is realized. At this time, the box cover 2 can be freely opened, and the staff can perform business operations on the USB certificate or USB flash drive inside the box body 1 and the box cover 2. Since the movement of the moving terminal 143 towards the docking port end necessarily corresponds to the operation of the authorized personnel, the box body 1 and the box cover 2 will only be automatically unlocked when used by the authorized personnel. When used by unauthorized personnel, on the one hand, it is impossible to connect to the USB certificate or USB flash drive inside the box body 1 and the box cover 2 through the external line 16. On the other hand, the cooperation between the safety lock catch 15 and the safety lock tongue 231 locks the box body 1 and the box cover 2, and unauthorized personnel cannot open the box body 1 and the box cover 2 to obtain the USB certificate or USB flash drive inside the box body 1 and the box cover 2;

[0057] When the staff finishes the business operation, the box body 1 and the box cover 2 can be closed. At this time, the moving terminal 143 needs to be separated from the docking port, that is, the moving terminal 143 moves towards the end away from the docking port. At this time, the moving terminal 143 will compress the air in the sealing cavity, increasing the air pressure in the sealing cavity. The air in the sealing cavity can enter the lock tongue groove 233. At this time, the air pressure outside the safety lock tongue 231 will be less than the internal air pressure. In this way, the safety lock tongue 231 will protrude from the lock tongue groove 233 under the action of the air pressure difference and cooperate with the safety lock catch 15 to lock the box body 1 and the box cover 2 again, realizing the automatic locking of the box body 1 and the box cover 2.

[0058] Such as Figure 10As shown, an elastic button 234 is inserted into the end face of the pneumatic lock 23. The outer end of the elastic button 234 is arc-shaped. In this way, when the box body 1 and the box cover 2 are closed, the end face of the safety lock catch 15 on the box body 1 can squeeze the elastic button 234, causing the elastic button 234 to move towards the inner end. A pressure block 235 is fixedly connected to the inner end of the elastic button 234. An automatic lock tongue 236 is provided on the side surface of the pressure block 235. A groove matching the automatic lock tongue 236 is formed at a position on the side surface of the safety lock tongue 231 close to the automatic lock tongue 236.

[0059] It should be noted that a spring is provided at one end of the automatic lock tongue 236 away from the safety lock tongue 231. This spring can transmit elastic force to the automatic lock tongue 236. When the box body 1 and the box cover 2 are in a closed state, the end face of the safety lock catch 15 on the box body 1 will squeeze the elastic button 234, causing the elastic button 234 to move towards the inner end. Inclined surfaces are provided at the intersections of the pressure block 235 and the automatic lock tongue 236. In this way, when the pressure block 235 moves, the pressure block 235 can squeeze the automatic lock tongue 236 through the inclined surface, causing the automatic lock tongue 236 to overcome the elastic force of the spring and move away from the groove on the side surface of the safety lock tongue 231. At this time, the safety lock tongue 231 can move freely, and the safety lock tongue 231 will extend out of the lock tongue groove 233 and cooperate with the safety lock catch 15.

[0060] It should be noted that when the authorized person opens the box body 1 and the box cover 2, the safety lock tongue 231 first retracts into the lock tongue groove 233, disengages from the safety lock catch 15, releases the lock between the box body 1 and the box cover 2, and enables the box body 1 and the box cover 2 to be freely opened. After the box body 1 and the box cover 2 are opened, the elastic force of the spring acts on the automatic lock tongue 236, causing the automatic lock tongue 236 to move towards the side of the safety lock tongue 231 and snap into the groove on the side of the safety lock tongue 231, achieving the locking of the groove on the side of the safety lock tongue 231 and ensuring that the authorized person can freely close the box body 1 and the box cover 2. When the authorized person completes the banking operation, they will first control the moving terminal 143 to disengage from the docking port, that is, the moving terminal 143 moves towards the end away from the docking port. At this time, the moving terminal 143 compresses the air in the sealing cavity, increasing the air pressure in the sealing cavity. The air in the sealing cavity can then enter the lock tongue groove 233. At this time, the automatic lock tongue 236 locks the safety lock tongue 231, so the lock tongue groove 233 is in a high-pressure state. When the authorized person closes the box body 1 and the box cover 2, the end face of the safety lock catch 15 on the box body 1 presses the elastic button 234, causing the elastic button 234 to move towards the inner end. There are inclined surfaces at the intersections of the pressure block 235 and the automatic lock tongue 236. In this way, when the pressure block 235 moves, the pressure block 235 can squeeze the automatic lock tongue 236 through the inclined surface, causing the automatic lock tongue 236 to overcome the elastic force of the spring and move away from the groove on the side of the safety lock tongue 231. At this time, the safety lock tongue 231 can move freely, and the high-pressure air in the lock tongue groove 233 will act on the inner end of the safety lock tongue 231, causing the safety lock tongue 231 to extend out of the lock tongue groove 233 and cooperate with the safety lock catch 15 to lock the box body 1 and the box cover 2.

[0061] As Figure 6 shown, the side wall of the secondary storage groove 21 is provided with a track groove 211, and several groups of adjusting columns 22 are arranged inside the secondary storage groove 21. Limiting plates 221 are fixedly connected to both sides of the adjusting column 22. It should be noted that track sliders matching the track groove 211 are fixedly connected to both ends of the adjusting column 22, so as to ensure that the adjusting column 22 can freely slide along the track direction in the track groove 211. When a USB certificate or a USB flash drive is placed in the secondary storage groove 21, the position of the adjusting column 22 can be adjusted according to the width of the USB certificate or the USB flash drive, so that the adjusting column 22 is stuck on the side of the USB certificate or the USB flash drive, and the limiting plate 221 fixedly connected to the side of the adjusting column 22 can be stuck on the front of the USB certificate or the USB flash drive, restricting the USB certificate or the USB flash drive in the secondary storage groove 21 and ensuring the stability of the USB certificate or the USB flash drive. A fastening bolt can be threadedly connected to the front of the adjusting column 22. After the position of the adjusting column 22 is determined, by rotating the fastening bolt, the fastening bolt is pressed against the surface of the secondary storage groove 21, and the position of the adjusting column 22 is fixed through friction.

[0062] As Figure 11As shown in the figure, an electromagnet 145 is provided inside the driver 141. One end of the moving terminal 143 close to the electromagnet 145 is fixedly connected to a permanent magnet 147. A return spring 146 is fixedly connected between the electromagnet 145 and the permanent magnet 147. When an authorized person turns on the circuit of the electromagnet 145, the electromagnet 145 will generate a magnetic field, and the magnetic pole of the electromagnet 145 is the same as that of the permanent magnet 147. In this way, a repulsive force will be generated between the electromagnet 145 and the permanent magnet 147, and this repulsive force can overcome the elastic force of the return spring 146, causing the moving terminal 143 to move towards the end away from the electromagnet 145.

[0063] The circuit connection command of the electromagnet 145 can set a key to improve the security of the USB certificate or USB flash drive.

[0064] The driver 141 can also be replaced by a linear driver. The output end of the linear driver is connected to the moving terminal 143. When an authorized person needs to use the USB certificate or USB flash drive, the linear driver can be turned on through the PC terminal. In this way, the linear driver will drive the moving terminal 143, causing the moving terminal 143 to move towards the docking port, unlocking the box body 1 and the box cover 2 and connecting the USB certificate or USB flash drive to the PC terminal at the same time.

[0065] As Figure 6 and Figure 7 shown in the figure, a rotating sleeve 17 is fixedly connected to the back of the box body 1, and a rotating seat 24 is fixedly connected to the back of the box cover 2 near the rotating sleeve 17. Rotating shafts 241 matching the rotating sleeve 17 are fixedly connected to both ends of the rotating seat 24. A torsion spring is nested on the side of the rotating shaft 241. It should be noted that the box body 1 is connected to the rotating shaft 241 through the rotating sleeve 17. When the box body 1 and the box cover 2 are unlocked, the torsion spring on the side of the rotating shaft 241 will apply a torque force to the rotating sleeve 17, causing the box cover 2 to automatically rotate and open.

[0066] Embodiment 4:

[0067] As Figure 12 shown in the figure, a microcontroller is provided on the storage part, and an operating program is loaded on the microcontroller. When the microcontroller is connected to the PC terminal, the operating program automatically generates a control interface on the PC terminal. The control interface generates virtual buttons corresponding one by one based on the control buttons 13. It should be noted that the USB certificate or USB flash drive inside the storage part is directly connected to the microcontroller, and the virtual buttons generated by the control interface can directly control the microcontroller. By controlling the microcontroller, the connection between the USB certificate or USB flash drive and the PC terminal can be controlled. The control interface generates a start button based on the physical partition mechanism 14. The start button sets an API key. Only after an authorized person inputs the API key can the microcontroller be controlled through the start button, and the microcontroller controls to open the physical partition mechanism 14.
