Problems solved by technology

Some jobs in these companies need to use intranet computers and ordinary computers at the same time, and some files need to be frequently exchanged from the two computers. Every time the data is copied, the intranet U disk must be pulled out between the two computers. After a certain number of times, the interface between the intranet U disk and the computer is easy to cause damage. At the same time, repeated plugging and unplugging of the intranet U disk also affects office efficiency.

Abstract

The invention provides a device for fast switch of USB equipment between an intranet computer and a common computer. The device is characterized by comprising a key unit, an indicator light unit and a connecting and converting unit. By the adoption of the device, security authenticated equipment including intranet USB flash disks and printers and scanners with USB interfaces can be used by staff conveniently between the intranet computer and the common computer, damage to the USB interfaces caused by frequent insertion and extraction of USB equipment can be avoided, and office efficiency is improved. Meanwhile, due to the fact that equipment including printers and scanners can be shared by two computers, office cost can be reduced greatly.

Description

technical field [0001] The invention relates to a USB device fast switching device, in particular to a USB device fast switching device between an intranet computer and a common computer. Background technique [0002] For the sake of information security, some companies do not allow intranet computers to connect to the Internet. If intranet computers exchange data with ordinary computers, they can only exchange data through a security-certified encrypted intranet U disk (or mobile hard disk). copy. Some jobs in these companies need to use intranet computers and ordinary computers at the same time, and some files need to be frequently exchanged from the two computers. Every time the data is copied, the intranet U disk must be pulled out between the two computers. After a certain number of times of use, the interface between the intranet U disk and the computer is easy to cause damage. At the same time, multiple times of unplugging and inserting the intranet U disk also affec...
