In order to better understand the technical scheme of the invention, the working process and the working principle of the invention are further explained below by taking the safe as an example as follows:

in the working process and the working principle, the panel 1 can be understood as the cabinet door of the safe,

when the safe is used, a key is firstly inserted into a lock hole of the spring lock 3 and is rotated by 90 degrees, the rotary lock tongue 6 is abutted against a door frame plate of the safe, the safe is locked, and the key is taken out;

specifically, when the operator rotates the timing knob 2 clockwise during time setting, the separating sleeve 25 is combined with the wheel axle of the movable gear 26, and the separating sleeve 25 drives the movable gear 26 to rotate together to the time setting position;

because the movable gear 26 and the idle gear 45 are in a meshed connection state, when the movable gear 26 rotates, the idle gear 45 is driven to rotate simultaneously, and because the retaining gear 37 of the spring 50, the idle gear 45 and the retaining stop piece 46 share one shaft, the spring 50 is properly tightened during coaxial rotation, energy is stored, the retaining stop piece 46 also rotates along with the shaft, and because the retaining gear 37 is movable, the retaining gear 37 does not have transmission capacity during coaxial rotation.

In the process, the conductive contact piece 10 is in contact with the conductive contact rod 8 to be powered on, the power supply P3 outputs electricity, the motor 7 is powered on, the motor runs, and the gear set assembly rotates.

After the lock core 5 is clamped, the timing knob 2 is rotated anticlockwise to return to the original position, in the resetting process, the knob shaft 24 and the separating sleeve 25 rotate, the separating sleeve 25 and the wheel shaft of the movable gear 26 are in a separated state, the movable gear is kept at a time setting position,

after the timing knob 2 returns to the original position, because the movable gear 26 does not reset, the pushing block 28 is not in contact with the guide block 30, the pin head of the second pin 29 pushes the second pin 29 under the action of the spring force, the pin head of the second pin 29 is inserted into the pin hole of the knob shaft 24, so that the knob shaft 24 is clamped, the knob shaft 24 can only rotate after the movable gear 26 resets, at the moment, the lock cylinder 5 and the knob shaft 24 are both clamped by the pins, and the panel 1 cannot be opened by external force.

And (4) connecting the steps: after the motor 7 runs, the motor output shaft 9 drives the gear E43 to rotate, and simultaneously transmits the rotation to the dual gear D42, the dual gear C41, the dual gear B40, the dual gear A38 and finally the rotation to the stopping gear 37, the wedge-shaped bulge 47 of the stopping gear 37 clamps the stopping baffle 46, and as the adjusting spring 51 is coaxial with the stopping baffle 46, the adjusting spring 51 slowly relaxes under the reverse torque force action of the stopping gear 37, the kinetic energy is released, and the coaxial idle gear 45 simultaneously rotates in the reverse direction.

The idle wheel 45 rotates reversely to drive the movable gear 26 to rotate reversely at the same time until the set time is up, the original position is returned, the pushing block 28 is contacted with the guide block 30, the pushing block 28 pushes the guide block 30 to move backwards, the pin head of the second pin 29 exits from the pin hole, and the timing knob 2 can rotate freely as being separated from the pin control;

and (3) synchronization: because the idler gear 45 rotates reversely, the driven gear 16 meshed with the idler gear also rotates reversely at the same time until the set time is up, when the movable retainer ring 13 is matched with the notch 271, the pin head of the movable pin 32 exits the pin hole of the lock cylinder sleeve 4, and the lock cylinder can rotate freely after a key is inserted.

And (3) synchronization: as the pin head of the movable pin 32 exits the pin hole of the lock cylinder sleeve 4, the conductive contact piece 10 is separated from the conductive contact rod 8, the power supply is cut off, the motor stops working, and the gear also stops rotating.

So far: the lock core 4 and the timing knob 2 are clamped by each internal bolt mechanism along with the rotation of the timing knob 2, the starting of the one-way motor 7 and the locking of the lock core and the timing knob assembly, so that the lock core and the timing knob assembly can not be opened by any external force, and can be controlled externally along with the withdrawing of each internal bolt mechanism.

Aiming at the hidden trouble brought by the existing product, the invention combines advantages and disadvantages, breaks the concept of the traditional lock function, adopts a brand-new unlocking idea, adds an internal bolt mechanism on the basis of the common lock function, sets a time unlocking mode at regular time, realizes the internal first unlocking only through internal mechanical motion in a set time period, then the external can be unlocked through a key, and the external can not be forcibly unlocked and pried to open through technical unlocking in work, thoroughly solves the unsafe factors brought by the existing lock, and better ensures property safety.
