Computer safety locking device based on fingerprint identification

Abstract

The invention relates to the technical field of computer safety, and discloses a computer safety locking device based on fingerprint identification, the computer safety locking device comprises a case and a rear cover, a mounting groove is formed in the case wall of the case, an electromagnet is fixedly mounted on the inner wall of the mounting groove, a blocking plate is fixedly mounted on the outer wall of the rear cover, and a positioning plate is fixedly mounted on the outer wall of the blocking plate; and a locking groove is formed in the positioning plate. When the blocking plate on the rear cover is clamped into the machine box, the positioning plate pushes the stand column upwards through the arc face of the top of the positioning plate and enables the stand column to be located above the positioning plate, the stand column moves upwards to drive the top plate to move upwards, the top plate moves upwards to trigger the microswitch on the inner wall of the installation groove, and the microswitch is triggered to enable the electromagnet to be electrified through the controller. And the electromagnet is electrified to outwards push the locking rod by utilizing magnetism, so that the locking rod extends out of the inner groove and is inserted into the locking groove in the positioning plate, and therefore, the positions of the rear cover and the blocking plate are locked by inserting the locking rod into the locking groove, and the rear cover and the blocking plate are prevented from being separated from the case.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a computer security locking device based on fingerprint identification. Background technique [0002] Computer is one of the electronic devices that people use in their life and work. Related components inside the computer, such as motherboards, CPUs, and graphics cards, are relatively expensive, and criminals often disassemble the main chassis to steal important internal components to make profits. Therefore, we need corresponding computer safety locking devices to lock the main chassis to prevent theft from happening. [0003] The Chinese patent announcement number is: CN110297528B invention patent, which discloses a computer security locking device based on fingerprint identification, including a chassis, a fixed block, a horizontal plate, a horizontal bar and an electric telescopic rod, and the left side of the chassis is provided with a The back board, the upper ...
