[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example

[0034] like Figure 1-5 As shown, compared with the lock mechanism of the safe deposit box disclosed in Chinese patent document CN 218881873 U, the technical solution of the lock mechanism of this embodiment reduces the return spring and increases the large shaft sleeve and the small shaft sleeve. The transmission mechanism can also be changed, and the photoelectric switch is replaced by a spring.

[0035] The usage process is as follows:

[0036] like Figure 1-5As shown, information is transmitted to the chip through any method such as fingerprints and password keys, and the chip controls the electric motor 7 to realize the forward rotation of the electric motor 7. The plastic rocker arm 9 is connected through the motor rotating shaft. The plastic rocker arm 9 is fixed on the rotating shaft of the electric motor 7 with screws. When the electric motor 7 rotates forward, the plastic rocker arm 9 is driven to rotate clockwise. After a certain angle, the surface A03 of the plastic rocker arm 9 collides with the surface A04 of the rotating disk 8, driving the rotating disk 8 to rotate clockwise. The left and right sides of the rotating disk 8 are respectively connected to one end of the connecting rod 11 with rivets 20. When the rotating disk 8 rotates clockwise, it drives the connecting rod 11 contracts inwardly, and the other end of the connecting rod 11 is connected to the threaded pin 12 with a locking nut 13. The threaded pin 12 is fixed to the sliding buckle 4 by pressure riveting. When the connecting rod 11 contracts inwardly, it drives the sliding buckle 4 to move inward, thereby releasing the door lock buckle to open the door. The waist-round hole surface B03 of the sliding buckle 4 contacts the surface B04 of the small shaft sleeve 6. The small shaft sleeve 6 is fixed to the pressure riveted stud 14 with a washer screw 5. The pressure riveted stud 14 is fixed to the mechanism base 1 by pressure riveting, so that the sliding buckle 4 can only slide left and right in the waist-round hole B03, and the small shaft sleeve 6 plays a role of rolling lubrication. The rotating disk 8 rotates clockwise, and when the convex edge of the surface A05 of the rotating disk 8 passes through the photoelectric sensor, i.e., the surface A06, of the photoelectric X-circuit board 2, the photoelectric circuit board 2 receives a blocking signal, and then the electric motor 7 is realized through the chip to rotate counterclockwise for a certain angle and then stop. When the rotating disk 8 rotates, the surface A08 of the rotating disk 8 collides with the surface A07 of the spring 10 and compresses the spring 10. The spring 10 is fixed to the riveted stud 14 with a washer screw 5. The riveted stud 14 is riveted to the rotating disk 8. When the spring 10 is compressed, the rotating disk 8 is driven to rotate counterclockwise, thereby driving the connecting rod 11 to extend and retract outward, moving the sliding buckle 4 outward, thereby resetting the sliding buckle 4. When the door panel is pressed down, the surface B01 of the door lock buckle and the B02 of the sliding buckle 4 collide, causing the sliding buckle 4 to move inward, driving the connecting rod 11 to contract inward, thereby causing the rotating disk 8 to rotate clockwise. Because the electric motor 7 is not started, the plastic swing arm 9 does not move, thereby compressing the spring 10. When the door lock buckle is buckled into the sliding buckle 4, the spring 10 releases the pressure, driving the rotating disk 8 to rotate counterclockwise, thereby driving the connecting rod 11 to extend and retract outward, thereby driving the sliding buckle 4 to move outward, so that the sliding buckle 4 buckles the door lock buckle. The large shaft sleeve 16 is limited on the pressure riveting stud 4 with a washer screw 13. The pressure riveting stud 4 is riveted on the mechanism base 2. The large shaft sleeve 3 rotates on the pressure riveting stud 14. When the lock buckle is pressed down, the surface B05 of the large shaft sleeve 3 collides with the surface B01 of the door lock buckle. Because the large shaft sleeve 3 can rotate, it plays a guiding auxiliary role.

[0037] When the electronic device fails, insert the key into the mechanical lock 16, and the mechanical lock 16 is fixed to the mechanism base 1 with a nut. Turn the key to drive the lock tongue 15 to rotate clockwise. The lock tongue 15 is fixed to the lock core of the mechanical lock 16 with a nut. The surface A02 of the lock tongue 15 is stuck in the slot of the rotating disk 8. When the lock tongue 15 is rotated, the lock tongue surface A02 collides with the surface A01 of the rotating disk 8, thereby driving the rotating disk 8 to rotate clockwise together. The left and right sides of the rotating disk 8 are respectively connected to one end of the connecting rod 11 with rivets 20. When the rotating disk 8 rotates clockwise, the connecting rod 11 is driven to retract inward. The other end of the connecting rod 11 is connected to the threaded pin 12 with a locking nut 13. The threaded pin 12 is fixed to the sliding buckle 4 by pressure riveting. When the connecting rod 11 retracts inward, it drives the sliding buckle 4. The movable buckle 4 moves inward, thereby releasing the door lock buckle to open the door, and the waist-round hole surface B03 of the sliding buckle 4 contacts the surface B04 of the small sleeve 6. The small sleeve 6 is fixed on the riveted stud 14 with a washer screw 5. The riveted stud 14 is riveted and fixed on the mechanism base 1, so that the sliding buckle 4 can only slide left and right in the waist-round hole B03, and the small sleeve 6 plays a rolling lubrication role. When the rotating disk 8 rotates, the surface A08 of the rotating disk 8 collides with the surface A07 of the spring 10 and compresses the spring 10. At this time, the spring 10 slides to the top of the surface A08 of the plastic swing arm 9 due to the compression surface A07, and the sliding buckle 4 cannot be automatically reset. Therefore, after each use of the mechanical lock, it must be reset when the electronic equipment is restored, and the key or fingerprint is used once with the correct password. Example

[0038] like Figure 6-9 As shown, compared with the lock mechanism of the safe deposit box disclosed in Chinese patent document CN 218881873 U, the technical solution of the lock mechanism of this embodiment adds a large shaft sleeve and a small shaft sleeve.

[0039] The usage process is as follows:

[0040] like Figure 6-9As shown, information is transmitted to the chip by fingerprint, and the chip controls the electric motor 16 to realize the forward rotation of the electric motor 16. The plastic rocker arm 15 is connected through the motor rotating shaft, and the plastic rocker arm 15 is fixed on the rotating shaft of the electric motor 16 with screws. When the electric motor 16 rotates forward, it drives the plastic rocker arm 15 to rotate clockwise. After a certain angle, the surface C02 of the plastic rocker arm 15 collides with the surface C01 of the small rotating disk 14, driving the small rotating disk 14 to rotate clockwise. The convex edge of the surface C04 of the small rotating disk 14 passes through the sensor of the photoelectric switch 10, that is, the surface C05, so that the photoelectric switch 10 receives a blocking signal, and then the electric motor 16 stops running through the chip. The small rotating disk 14 is fixed with a riveting shaft 13 in the form of a riveting shaft. One end of the connecting rod 9 is fixed to the riveting shaft 13 with a retaining ring. When the small rotating disk 14 rotates clockwise, it drives the riveting shaft 13 to rotate, thereby driving the small connecting rod 9 to retract inward. The other end of the small connecting rod 9 is connected to the spring pin 2 with an axis retaining ring. The spring pin 2 is fixed to the small sliding buckle 8 by riveting. When the small connecting rod 9 retracts inward, it drives the small sliding buckle 8 to move inward, thereby releasing the door lock buckle to open the door. The waist round hole surface D04 and surface D07 of the small sliding buckle 8 are in contact with the surface D05 and surface D08 of the small shaft sleeve 3 respectively. The small shaft sleeve 3 is fixed to the riveting stud 4 with a washer screw 7. The riveting stud 4 is fixed to the mechanism base 1 by riveting, so that the small sliding buckle 8 can only slide left and right in the waist round hole, and the small shaft sleeve 3 plays a rolling lubrication role. The spring pin 2 on the small sliding buckle 8 and another spring pin 2 are riveted and fixed on the mechanism base 1. The two spring pins 2 are connected by a spring 5. When the small sliding buckle 8 contracts inward, the spring 5 is stretched. When the small connecting rod 9 stops contracting, the spring 5 contracts due to elastic force and pulls the small sliding buckle 8 outward, thereby resetting the small sliding buckle 8. When closing the door, the door lock buckle is pressed on the surface D03 of the small sliding buckle 8. The small sliding buckle 8 shrinks inward due to the pressure of the door lock buckle, and the spring 5 is stretched, so that the door lock buckle is pressed onto the base 1. The spring 5 shrinks due to the elastic force and pulls the small sliding buckle 8 outward, so that the small sliding buckle 8 is reset, thereby buckling the door lock buckle. The large sleeve 3 is limited on the riveting stud 4 with a washer screw 7. The riveting stud 4 is riveted to the base 1 of the mechanism. The large sleeve 3 rotates on the riveting stud 4. When the lock buckle is pressed down, the surface D01 of the large sleeve 3 collides with the surface of the door lock buckle. Since the large sleeve 3 is rotatable, it plays a guiding auxiliary role.

[0041] When the electronic device fails, insert the key into the mechanical lock 11, the mechanical lock 11 is fixed to the mechanism base 1 with a nut, turn the key, drive the lock tongue 12 to rotate clockwise, the lock tongue 12 is fixed to the lock core of the mechanical lock 11 with a nut, the surface C03 of the lock tongue 12 is stuck in the slot of the small rotating disk 14, when the lock tongue 12 is rotated, the lock tongue surface C03 collides with the surface C01 of the small rotating disk 14, thereby driving the small rotating disk 14 to rotate clockwise together, the small rotating disk 14 is fixed with a riveting shaft 13 in the form of a riveting, one end of the small connecting rod 9 is fixed to the riveting shaft 13 with a retaining ring, and the small rotating disk 14 drives the riveting shaft 13 to rotate clockwise when the small rotating disk 14 rotates clockwise. The rivet shaft 13 rotates, thereby driving the small connecting rod 9 to retract inward. The other end of the small connecting rod 9 is connected to the spring pin 2 with a shaft retaining ring. The spring pin 2 is fixed to the small sliding buckle 8 by riveting. When the small connecting rod 9 retracts inward, it drives the small sliding buckle 8 to move inward, thereby releasing the door lock buckle to open the door. The waist round hole surface D04 and surface D07 of the small sliding buckle 8 are in contact with the surface D05 and surface D08 of the small shaft sleeve 3 respectively. The small shaft sleeve 3 is fixed to the riveted stud 4 with a washer screw 7. The riveted stud 4 is fixed to the mechanism base 1 by riveting, so that the small sliding buckle 8 can only slide left and right in the waist round hole, and the small shaft sleeve 3 plays a role of rolling lubrication. The spring pin 2 on the small sliding buckle 8 and another spring pin 2 are riveted and fixed on the mechanism base 1. The two spring pins 2 are connected by a spring 5. When the small sliding buckle 8 contracts inward, the spring 5 is stretched. When the small connecting rod 9 stops contracting, the spring 5 contracts due to elastic force and pulls the small sliding buckle 8 outward, thereby resetting the small sliding buckle 8. When closing the door, the door lock buckle is pressed on the surface D03 of the small sliding buckle 8. The small sliding buckle 8 shrinks inward due to the pressure of the door lock buckle, and the spring 5 is stretched, so that the door lock buckle is pressed onto the base 1. The spring 5 shrinks due to the elastic force and pulls the small sliding buckle 8 outward, so that the small sliding buckle 8 is reset, thereby buckling the door lock buckle. The large sleeve 3 is limited on the riveting stud 4 with a washer screw 7. The riveting stud 4 is riveted to the base 1 of the mechanism. The large sleeve 3 rotates on the riveting stud 4. When the lock buckle is pressed down, the surface D01 of the large sleeve 3 collides with the surface of the door lock buckle. Since the large sleeve 3 is rotatable, it plays a guiding auxiliary role.
