The working principle is as follows:

the working principle of the main body part 1 is as follows:

when the lock is closed, the bolt 102 is manually pulled, the bolt 102 drives the bolt 103 to move, the bolt 103 extends out to be locked, when the bolt 103 moves, the bolt 103 drives the two connecting rods a104 to move upwards through the inclined groove, and the connecting rods a104 drive the power output device to work and simultaneously be locked; and the lock can be closed, and the lock can be opened only through a newly generated password when the lock is opened.

When the connecting rod a104 drives the power transmission device to work, the operation conditions of the components inside the code part 2 are as follows: the connecting rod a104 firstly drives the rotating shaft 221 to rotate through the telescopic rod 222, the rotating shaft 221 drives the special-shaped cam to rotate, and when the special-shaped cam rotates, the cylindrical cam 230 drives the blocking piece to rotate for a certain angle through the limiting groove b224, so that the elastic piece b225 is positioned at the lower end of the pressing piece; meanwhile, the bayonet b233 clamps the protrusion on the limit plate 212, so that the limit plate 212 overcomes the pulling force of the rack 213 to drive the rack 213 to move, and the rack 213 is meshed with the gear 220; and bayonet a232 is blocked with the projection on the positioning plate 215, so that the whole lock is blocked and the lock cannot be opened.

When the lock is unlocked, a corresponding password is input, the button 208 is pressed, the button 208 drives the limiting block 207 to move downwards, the limiting block 207 drives the conductive column b205 to move downwards, the conductive column b205 drives the corresponding elastic sheet c227 to move downwards through the connecting rod b206, when the conductive column b moves, the protrusion of the elastic sheet c227 is clamped with the inclined plane protrusion at one end of the elastic sheet b225, and when the button 208 is released, the elastic sheet c227 cannot reset;

when the password is correctly input, the bump 228 under the elastic piece c227 presses the shielding plate 219 to move the shielding plate 219 downward, the shielding plate 219 presses the positioning plate 215 to move downward, at this time, the protrusion on the positioning plate 215 is bounced off from the detent a232, the cylindrical cam 230 is reset due to the pulling force generated by the tension spring b234, and then the rotating shaft 221 is driven to rotate, the rotating shaft 221 drives the telescopic rod 222 to move, and the telescopic rod 222 drives the connecting rod a104 to move, so as to unlock;

when the cylindrical cam 230 is reset, the bayonet pin b233 is separated from the protrusion on the limiting plate 212, the limiting plate 212 is reset due to the pulling force of the tension spring a214, the rack 213 drives the gear 220 to rotate, after the resetting of the limiting plate 212 is completed, the rack 213 is not meshed with the gear 220, the gear 220 drives the rotor 218 to continue to rotate and slowly stop due to inertia, that is, the rotor 218 stops at a random position, that is, the shielding plate 219 stops at a random position, so that the randomness of the next unlocking password is realized;

when the password is generated, the shielding plate 219 will block between the infrared emitter a216 and the infrared emitter b229, so that the sensor 210 is closed, at this time, the sensor 210 will send the position of the sensor 210 in the closed state to the processor 211, and after the processor 211 recognizes the position, the obtained four-digit password is sent to the receiving end through the internet, so as to unlock the lock in the next time.
