Description

A computer multifunctional expansion device

technical field

The utility model relates to the technical field of computer accessories, in particular to a computer multifunctional expansion device.

Background technique

There are many interfaces on the back of the desktop computer, and these interfaces usually have only one, which has certain limitations in use. The memory card for storing data is one of our commonly used storage devices, and is widely used in mobile phones, digital cameras, portable computers, MP3 and On other digital products, but desktop computers generally do not have special equipment that can read these memory cards, and can only read the data in the memory card with the help of an external card reader, which is very inconvenient to use; in addition, the USB interface is used as a commonly used data transmission interface , the interface on the panel of the host computer cannot meet our needs. If you want to use other USB interfaces, you must use the USB interface on the back of the host computer, which is very inconvenient to use; The network connector cannot be shared. It is very inconvenient if the desktop computer needs to be connected to a projector. There is only one VGA port on the back of the desktop computer, which has been connected to the monitor and cannot be connected to the projector.

Therefore, in view of the above situation, a kind of computer multi-functional expansion device with simple structure, easy to use, easy to read memory card, and multiple USB interfaces, network cable interfaces and VGA interfaces can be conveniently used is designed by the inventor. problems faced.
