[0041] As a specific technical solution of this embodiment, connecting plates 33 are fixedly provided on both sides of the fingerprint lock upper plate 31, and connecting holes 21 are opened inside the connecting plates 33. The connecting plates 33 are fixedly connected to the upper box body 2 by rivet bolts, and a sponge pad is fixedly provided inside the upper box body 2.

[0042] In this embodiment, the connection hole 21 inside the connection plate 33 is fixedly connected to the interior of the upper box body 2 with rivet bolts, and the sponge pad wraps around the fingerprint lock assembly 3.

[0043] As a specific technical solution of this embodiment, a connection groove 311 is opened on the front of the fingerprint lock upper plate 31, and the interior of the connection groove 311 is movably connected to the surface of the socket 38. A battery 35 is arranged on the top of the fingerprint lock lower plate 34, and the motor 395 and the fingerprint recognition device 36 are electrically connected to the battery 35.

[0044] In this embodiment, the battery 35 uses a No. 5 dry cell battery 35 , and an external 5-6V backup power supply can also be connected through the socket 38 . The battery 35 is used to power the motor 395 , the lighting lamp 341 and the fingerprint recognition device 36 .

[0045] As a specific technical solution of this embodiment, a lighting lamp 341 is arranged on the top of the fingerprint lock lower plate 34, and the lighting lamp 341 is electrically connected to the battery 35. A sponge pad is fixedly arranged on the bottom surface of the inner wall of the lower box body 11, and a fixing hole 15 is opened at the bottom of the lower box body 11, and a resin pad glue is arranged inside the fixing hole 15.

[0046] In this embodiment, the fixing hole 15 can be filled with resin pad glue and sealed to make the bottom of the lower box body 11 airtight. At this time, it is practical to cooperate with the safety lock. The resin pad glue can also be removed and fixed to the desktop or wall with bolts, or it can be fixed to the fixing frame 5. When the lock body 391 touches the travel switch 399, the lighting lamp 341 turns on to illuminate the interior of the lower box body 11. When the upper box body 2 and the lower box body 11 are closed, the lighting lamp 341 goes out.

[0047] When in use, the fingerprint is identified by the fingerprint recognition device 36. After the fingerprint verification is successful, the motor 395 drives the eccentric wheel 396 to rotate, and the eccentric wheel 396 pushes the lock body 391 to move horizontally to the left. When the groove 3911 hits the travel switch 399, the locking block 398 moves from the oblique mouth 37 to the inside of the limit groove and is deflected upward by the torsion spring rebound to hit the right side of the inner wall of the limit groove, so that the lock body 391 is fixed and cannot be reset. At the same time, the lock body 391 drives the first claw 393 and the second claw 394 to disengage from the engagement with the groove 18. At this time, under the action of the torsion spring body 44, the upper hinge 41 drives the upper box body 2 to automatically flip over, and when the travel switch 399 is touched, the lighting lamp 341 is turned on, so that the interior of the lower box body 11 is illuminated, which is convenient for the user to find items. Within 0-1 second after the travel switch 399 is touched, the motor 3 The rotation of 95 drives the eccentric wheel 396 to reset (opposite to the rotation direction of pushing the card lock body 391, rotating 180 degrees). When the upper box body 2 and the lower box body 11 are closed, the protrusion 19 inside the rightmost card slot 18 abuts against the locking block 398, so that the locking block 398 abuts against the limit groove. The part of the limit groove deflects downward and abuts against the oblique opening 37, and slides along the oblique opening 37 to the bottom of the fingerprint lock lower plate 34. At this time, the card lock body 391 is free from the restriction of the locking block 398, and the spring 392 rebounds and abuts the card lock body 391 to move to the right, so that the card lock body 391 drives the first claw 393 and the second claw 394 to engage and lock with the two card slots 18 respectively, thereby fastening the upper box body 2 and the lower box body 11. The spring 392 cooperates with the torsion spring to make the card lock body 391 slowly return to its position, thereby deriving the upper box body 2 and the lower box body 11 of the silent switch, and the operation of the device is completed through the above.

[0048] In summary, the biometric fingerprint safe, by setting the lower box component 1, the upper box body 2, the fingerprint lock component 3 and the automatic flip cover component 4, the device fingerprint unlocking, quick and safe, the fixing belt 13 and the sponge pad better protect the placed items, the lower box body 11 and the upper box body 2 have good sealing after closing, the locking component 39 is simple to operate and has strong maneuverability. It can replace the mechanical lock of the transmission, and is not only used in the field of safes, but also applicable to all fields using traditional lock structures, and has broad application prospects.
