Simultaneously, the cam 221 on the lock tongue 22 pushes the movable frame 13 to move a certain distance along the movable frame guide post 10, so that the positioning teeth 162 and the step teeth 161 on the coding frame 7 are separated from the limitation of the step hooks 41 and the positioning hooks 42, and the coding frame 7 returns to the position under the action of the coding frame spring.
When the other end of the lock tongue control board 11 is limited by the limiting piece 24, any key 3 can be pressed again, the coding frame 7 and the movable frame 13 move for a certain distance along the movable frame guide post 10, so that the positioning teeth 162 and the step teeth 161 on the coding frame 7 are separated from the limitation of the step hooks 41 and the positioning hooks 42, the coding frame 7 returns to the proper position under the action of the coding frame spring, and any key can be pressed for a plurality of times, thereby achieving the peep-proof effect. When the door is opened, the lock mechanism props against the lock tongue 22 to enable the lock tongue 22 to rotate leftwards for a certain angle, and the door is opened. When the lock tongue 22 rotates through an angle, the limiting piece 24 is deformed under the action of the cam 221, the limiting piece 24 releases the limitation on the lock tongue control plate 11, and the lock tongue control plate 11 is reset.
When the wrong key 3 is pressed, the key column 17 is propped against the coding block 15, and the coding block 15 is fixed on the coding frame 7 through the coding block locking plate 8 at ordinary times, so that the coding block 15 drives the coding frame 7 to move a distance. At this time, the positioning teeth 162 and 161 on the code frame 7 are separated from the limitation of the step hook 41 and the positioning hook 42, the code frame 7 returns to the original position under the action of the code frame spring, the code frame 7 cannot move downwards step by pressing the wrong code, and the lock cannot be opened.
The embodiment can also press any key for a plurality of times before pressing the correct password so as to achieve the peep-proof effect. The embodiment can also press any key for several times before and after pressing the correct password, so as to achieve better peep-proof effect.
During code changing, a code changing key matched with a code changing shaft 191 is inserted into the back of the coded lock, a certain angle is moved clockwise, firstly, a code block locking plate shifting knob 1912 shifts the code block locking plate to move, the limit on the code block is released, then a pull plate shifting plate 1911 is cleared, a slope on two sides of the pull plate is cleared to jack up the clear plate, the clear plate presses the code block to move together for a certain distance, the code block returns to the original position, the code changing key is loosened, the code changing shaft returns to the original position under the action of a code changing shaft torsion spring, a new code can be input at the moment, the stepping action is the same as unlocking, the code block can move for a certain distance when a key column presses the code block every time, after the input is completed, the code block locking plate shifting knob 1912 shifts the other side of the code block locking plate, and the code block locking plate moves to lock the code block. And (3) loosening the code changing key, and returning the code changing shaft to the original position under the action of the code changing shaft torsion spring to complete the code changing.
When the number of the coded bits is adjusted, the coded lock bottom plate is opened, the unlocking plate 23 is loosened, the coded frame 7 is moved to the number of bits required by users, the unlocking plate 23 is shifted to the unlocking position, and the unlocking plate 23 is screwed tightly. The fixed bottom plate can be used by pressing any key to return to zero.
The embodiment also provides an intelligent mechanical key coded lock, which comprises the lock cylinder.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
