Problems solved by technology
[0003] However, during the use of existing fingerprint combination locks, after people identify their fingerprints, traces of people's fingerprints will remain on the fingerprint touch screen. If criminals use these residual traces, they may forge fingerprints and enter the laboratory. Cause serious consequences. In addition, for some medical and chemical laboratories, some bacteria or even viruses may remain after people are injured after doing experiments inside. When people check in and out of the laboratory, bacteria may remain in the On the fingerprint touch screen, if a large number of people come in and out, cross-infection is prone to occur, and there are certain security risks. Therefore, it is necessary to design a security system for scientific research laboratories using fingerprint password locks to solve the above problems

The invention discloses a safety system of the fingerprint coded lock for the scientific research laboratory, which comprises a mounting block. A mounting groove is formed in the side wall of the mounting block, and a fingerprint touch screen is arranged in the mounting groove; an erasing mechanism for erasing fingerprints is arranged on the mounting block, the erasing mechanism comprises a placement cavity formed in the mounting block, and the inner wall of the placement cavity is elastically connected with a permanent magnet plate through a plurality of pressure springs; the permanent magnetplate extends into the mounting groove and is fixedly connected with a moving block, a placement groove is formed in the side wall of the moving block, and the fingerprint touch screen is fixedly connected with the inner wall of the placement groove; and a fixing cavity is formed in the mounting block, a magnetic strip is fixedly connected to the inner wall of the fixing cavity, and a wire frameis fixedly inserted into the side wall of the magnetic strip. Dust on the fingerprint touch screen can be erased, fingerprint traces remaining on the fingerprint touch screen are prevented from beingutilized by lawbreakers, bacteria can also be prevented from remaining on the fingerprint touch screen, and the cross infection phenomenon is prevented.
Description
technical field [0001] The invention relates to the technical field related to coded locks, in particular to a security system for fingerprint coded locks used in scientific research laboratories. Background technique [0002] In some important scientific research laboratories, there are a large number of important experimental instruments and a lot of confidential test data. In order to prevent criminals or idlers from entering the laboratory, the door of the general laboratory will use fingerprint password The lock is used for identification, and only professionals who have recorded fingerprints can enter the laboratory. [0003] However, during the use of existing fingerprint combination locks, after people identify their fingerprints, traces of people's fingerprints will remain on the fingerprint touch screen. If criminals use these residual traces, they may forge fingerprints and enter the laboratory. Cause serious consequences. In addition, for some medical and chemic...
