a flash memory device

Abstract

The invention discloses a flash memory device which includes a USB flash disk and a locking mechanism. The flash memory device is characterized in that the locking mechanism is provided with a lock cylinder mechanism therein; the lock cylinder mechanism includes an upper sealing plate, a lower sealing plate, a U-shaped tube, top blocks, springs, connecting bridges, spring placing holes, push-out keys and mold cores; the upper sealing plate is provided with the lower sealing plate thereon; the symmetrical mold cores matching each other are disposed in the middle of the upper sealing plate and the lower sealing plate respectively; two ends of the U-shaped tube penetrate respectively through two sides of the sealing plates to rotate cooperatively; the two ends of the U-shaped tube penetrate into the mold cores; the two ends of the U-shaped tube are provided with the first and second top blocks; two ends of the interior of the mold cores are provided with the spring placing holes; one end of each spring is mounted in the corresponding spring placing hole; the other end of each spring is connected to one end of the corresponding connecting bridge; and the other end of each connecting bridge is provided with the corresponding push-out key.

Description

technical field [0001] The present invention relates to a flash memory device. Background technique [0002] U-disk, the full name of USB flash drive, the English name "USB flash disk". It is a miniature high-capacity mobile storage product that uses a USB interface and does not require a physical drive. It is connected to a computer through a USB interface to achieve plug-and-play. The name of the U disk originated from a new type of storage device produced by Netac Technology, named "U disk", which is connected with a USB interface. After the U disk is connected to the USB interface of the computer, the data of the U disk can be exchanged with the computer. Since Netac has registered patents for equipment with similar technologies produced later, they can no longer be called "USB disks", but are renamed "U disks" with homophonic sounds. Later, the name U disk was widely known because of its simplicity and ease of remembering, and it was one of the mobile storage devices...

Problems solved by technology

However, the anti-theft and privacy protection of the U disk is still insufficient. There may be important files or privacy in the U disk. In order to prevent theft, an anti-theft lock must be added on the original basis.
