Abstract
Description
Technical Field
[0001] The present invention belongs to the field of information communication technology, and in particular relates to a universal serial physical locking device. Background Art
[0002] Considering factors such as information security and virus threats, many companies and enterprises usually do not allow employees to connect external USB flash drives or other USB devices to their computers at will. At present, in most cases, it is only possible to educate computer users on safety awareness. Since the USB interface on the computer is exposed and easy to plug and unplug, some people still make mistakes due to neglect or forgetfulness, and it is impossible to achieve a good disabling effect. The existing technology prevents the USB port from being accidentally plugged into other devices by sealing the port with a sticky tape with a warning slogan, or blocking the port with a baffle with a warning slogan. The universal serial interface (USB port) physically isolated from network devices cannot effectively prevent the measures from being mistakenly connected to external network devices. The existing technology only serves as a reminder, the blocking object can be moved at will, there is no forced locking effect, there is uncertainty in the management of the universal serial interface, and the absolute information security of the port cannot be guaranteed. Summary of the invention
[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a universal serial physical locking device which is easy to install, portable to operate, durable and has good confidentiality effect.

[0005] A limiting groove is arranged inside the clamping block, and a limiting block is arranged outside the top head.
[0006] The top head and the clamping block are both designed with inclined surfaces, and a pad is arranged on the left side of the top head.
[0007] A convex block is arranged on the left side of the lock head, and a concave seat is arranged on the right side of the unlocker, and the concave seat and the convex block cooperate with each other.
[0008] A shifting block is arranged on the outer side of the screw rod, and anti-skid patterns are arranged on the surface of the shifting block.
[0009] A reset mechanism is arranged inside the shift block, and the reset mechanism comprises a baffle and a spring. The baffle is fixed to the outside of the ejector pin, and a spring is arranged between the baffle and the shift block.
[0010] A button is fixedly arranged on the outer end of the ejector pin.
[0011] A hinge shaft is arranged outside the unlocker, and an upper protective cover and a lower protective cover are arranged on the upper and lower sides of the hinge shaft respectively.
[0012] The lower sides of the upper protective cover and the lower protective cover are both provided with hanging buckles.
[0013] The beneficial effects of the present invention are as follows: when the device is in use and the plug-in port needs to be locked, the lock head is docked with the unlocker, the screw rod is rotated to make the screw rod enter the interior of the connecting tube, and then the lock head and the unlocker are temporarily fixed, and the lock head is sent into the interior of the plug-in port through the unlocker to make the lock head contact with the bottom of the plug-in end head, at this time the top head retracts into the interior of the shell, and the top head squeezes the card block to the outside of the outlet groove, and the card block is clamped in the end groove of the plug-in port, and then the screw rod is rotated to disengage the screw rod from the connecting tube, and the unlocker can be removed, at this time the lock head blocks the plug-in port, Under the action of the card block, the lock cannot be pulled out forcibly, and the plug-in port can be well protected. When the lock needs to be taken out, the unlocker is aligned with the lock, and under the action of the protrusion and the recess, the effect of quick alignment can be achieved. The screw is rotated to enter the connecting cylinder, and then the ejector is pressed to push the ejector head outward. During the movement of the ejector head, the card block is driven to be recovered into the shell. At this time, the card block releases the restriction on the end slot, and the lock can be pulled out through the unlocker, thereby releasing the restriction on the plug-in port. The present invention has the advantages of easy installation, portable operation, durability and good confidentiality. BRIEF DESCRIPTION OF THE DRAWINGS
