In other embodiments, the trigger 133 may be located on the door panel 4 and the control switch 6 may be located on the bolt head arm 13.

In this embodiment, the operation principle and the use process of the door lock mechanism of the safe are as follows.

Taking fig. 4 as an initial state, at this time, the box body 5 and the door panel 4 are in a locked state, the second guide portion 42 is close to one side of the second guide hole 312 far from the bolt head 14, the first guide portion 41 is close to one side of the first guide hole 132 far from the bolt head 14, the first eccentric pin 121 is located on the right side of the main turntable 11 and close to one end of the first strip-shaped hole 131, and the second eccentric pin 351 is located on the right side of the emergency turntable 35 and close to the upper end of the second strip-shaped hole 311.

When the door panel 4 needs to be opened in a normal state, a user finger acts on the main password input portion 22 (in this embodiment, the finger presses the fingerprint acquisition device), the main controller 21 detects that the control switch 6 is in an un-triggered state (that is, the control switch 6 and the trigger portion 133 are away from each other at this time, the door panel 4 is in a closed state), the main controller 21 compares a fingerprint acquired by the fingerprint acquisition device with a fingerprint texture input in advance, and if the fingerprint acquired by the fingerprint acquisition device and the fingerprint texture input in advance are successfully matched, the main controller 21 commands the main motor 11 to perform an opening action. Then, the main motor 11 drives the main rotating disk 12 to rotate, the first eccentric pin 121 of the main rotating disk 12 slides in the first strip-shaped hole 131 and drives the bolt head arm 13 to transversely slide, and the bolt head 14 on the bolt head arm 13 transversely retracts, so that the box body 5 and the door panel 4 are unlocked. The process of fig. 4 to 8 is a process of unlocking the door panel 4 and the cabinet 5 by acting on the main code input part 22 in a normal state, in which the position of the main motor 11 with respect to the door panel 4 is not changed.

When the door panel 4 needs to be closed in a normal state, similarly, a finger of a user acts on the main password input portion 22 (in this embodiment, the finger presses the fingerprint collector), at this time, the main controller 21 may not compare the collected fingerprint with the fingerprint texture recorded in advance, the main controller 21 detects that the control switch 6 is in a trigger state (that is, the control switch 6 abuts against the trigger portion 133 at this time, and the door panel 4 is in an open state), then, the main controller 21 controls the main motor 11 to start, the main motor 11 drives the main rotating disc 12 to rotate, the first eccentric pin 121 of the main rotating disc 12 slides in the first strip-shaped hole 131 and drives the bolt head arm 13 to slide transversely, and the bolt head 14 on the bolt head arm 13 extends transversely along with the first strip-shaped hole, so that the box body 5 and the door panel 4 are locked. The process of fig. 8 to 4 is a process of gradually locking the door panel 4 and the cabinet 5 by acting on the main code input part 22 in a normal state in which the position of the main motor 11 with respect to the door panel 4 is not changed.

When needing emergent unblock door plant 4, for example when main motor 11 condition such as break down, and can't unblock box 5 and door plant 4, can come emergent unblock through starting emergent motor 34, specifically be: an emergency power supply such as a charger is inserted through an emergency interface 36, after the emergency power supply is connected, an emergency password input part 32 (a password input keyboard in the embodiment) on an operation panel is lighted, and 0-9 is displayed, the position of a star and a #, after a user inputs a keyboard password, an emergency controller 33 compares the input keyboard password with the stored keyboard password, if the comparison is successful, the emergency controller 33 controls an emergency motor 34 to start, the emergency motor 34 drives an emergency turntable 35 to rotate, a second eccentric pin 351 of the emergency turntable 35 slides in a second strip-shaped hole 311 and drives an emergency sliding plate 31 to slide transversely, the transverse sliding of the emergency sliding plate 31 drives a main motor 11 on the emergency sliding plate 31 to slide transversely together, and because the main motor 11, the main turntable 12, a bolt head arm 13 and a bolt head 14 are static relative to the emergency sliding plate 31, the emergency sliding plate 31 slides transversely, finally, the bolt head 14 also slides transversely and retracts transversely, so that the box body 5 and the door panel 4 are unlocked.

When the emergency motor 34 is not started, the second eccentric pin 351 is close to the first end of the second strip-shaped hole 311 (i.e. the top inner wall of the second strip-shaped hole 311, see fig. 5), see fig. 5, and at this time, the direction of the connecting line of the rotation center 352 of the emergency rotary disk 35 and the center of the second eccentric pin 351 is parallel to the sliding direction of the emergency sliding plate 31. After the emergency motor 34 is started, as shown in fig. 5, the emergency turntable 35 starts to rotate clockwise, the second eccentric pin 351 gradually moves downward, after the second eccentric pin 351 moves to abut against the second end 311b of the second strip-shaped hole 311 (see fig. 9, that is, the bottom inner wall of the second strip-shaped hole 311 as seen in fig. 5), the emergency turntable 35 continues to rotate clockwise, the second eccentric pin 351 continues to move upward, when the second eccentric pin 351 moves to abut against the first end of the second strip-shaped hole 311 (see fig. 5, that is, the top inner wall of the second strip-shaped hole 311), the emergency controller 33 stops the emergency motor 34 after detecting a corresponding change state of the current and voltage, and at this time, as shown in fig. 7, the extending direction of a connecting line between the rotation center 352 of the emergency turntable 35 and the center of the second eccentric pin 351 is consistent with the sliding direction of the emergency sliding plate 31. The processes of fig. 4 to 6 and the processes of fig. 5 to 7 are all processes of unlocking the door panel 4 and the cabinet 5 by acting on the emergency password input part 32 in the emergency state, in which the position of the main motor 11 with respect to the door panel 4 is changed.

The activation of the emergency motor 34 can also be used to lock the box 5 and the door panel 4 if the main motor 11 is temporarily not repaired, in particular: after the user presses the door closing key at the emergency password input part 32, the emergency controller 33 controls the emergency motor 34 to start, the emergency motor 34 drives the emergency rotary disc 35 to rotate, the second eccentric pin 351 of the emergency rotary disc 35 slides in the second strip-shaped hole 311 and drives the emergency slide plate 31 to slide transversely, the transverse sliding of the emergency slide plate 31 drives the main motor 11 on the emergency slide plate 31 to slide transversely together, and similarly, because the main motor 11, the main rotary disc 12, the bolt head arm 13 and the bolt head 14 are static relative to the emergency slide plate 31 at the moment, when the emergency slide plate 31 slides transversely, the bolt head 14 finally slides transversely and extends transversely, so that the box body 5 and the door panel 4 are locked. The processes of fig. 6 to 4 and the processes of fig. 7 to 5 are processes in which the door panel 4 and the cabinet 5 are gradually locked by acting on the emergency code input part 32 in the emergency state, and in which the position of the main motor 11 with respect to the door panel 4 is changed. Thus, when the main lock 2 breaks down, even if the main lock 2 is not maintained, the door plate 4 and the box body 5 can be locked through the emergency lock 3, so that the normal use of the safe case is ensured, and the service cycle of the safe case is prolonged.
