Mechanical-lock USB (universal serial bus) flask disk

Abstract

The invention discloses a mechanical-lock USB (universal serial bus) flask disk. The mechanical-lock USB flask disk comprises a USB flask disk body (1) with a storage circuit and a cover body (2), and the mechanical-lock USB flask disk also comprises a mechanical lock which is arranged in the USB flask disk body (1), wherein the mechanical lock consists of a lock body (4), a digital wheel (5) and a lock column (6), the digital wheel (5) is fixed on the lock body (4), and the lock body (4) is connected with the lock column (6); the cover body (2) is fixedly provided with a convex member (3), and the USB flask disk body (1) is provided with an open slot (7) which is used for the convex member (3) to insert; the lock body (4) controls the lock column (6) to stretch out when the digital wheel (5) rotates to a password, and the lock column (6) locks the convex member (3) which is inserted into the open slot (7). By adopting the mechanical-lock USB flask disk, the cover body can be opened when the digital wheel rotates to the password; moreover, when the password is incorrect, the cover body cannot be opened, the USB flask disk can be locked when not in use, and the application safety of the USB flask disk can be greatly improved.

Description

Technical field [0001] The invention relates to a U disk, in particular to a U disk with a lock, and belongs to the technical field of storage media. Background technique [0002] With the continuous development of informatization, data information becomes more and more important. For data information in electronic form, storage media, such as mobile hard drives, U disks, etc., are often used when saving or copying. The U disk is a common small storage medium. It is a micro high-capacity mobile storage product that uses a USB interface and does not require a physical drive. It is connected to the computer through the USB interface to achieve plug and play. The traditional U disk includes a U disk body and a cover. The cover is covered on the U disk body. The U disk body has its own storage circuit so that data can be stored or retrieved. Such a U disk is small in size and light in structure. It is very convenient to use and carry. However, such a USB flash drive lacks security...

AI Technical Summary

Problems solved by technology

However, such U disks lack consideration in safety, because traditional U disks can be plugged into computers for use after opening the cover, and if the U disk is lost and there is important data information in the U disk, it will be lost immediately after being picked up by others. The stored data can be seen, resulting in the leakage of data information, which threatens the storage security of the U disk, that is, the traditional U disk itself does not have encryption, and the U disk cannot be locked when it is not in use, and the security is not good. high
