Generally, when a key is inserted into the key cavity 13 from the key opening 75, so that the key bit jacks up the locking block 12, the connecting rod 54 drives the locking slide block 52 to move upwards, so that the locking opening 53 moves upwards, so that the locking opening 53 is aligned and communicated with the locking slide cavity 56, when each locking opening 53 is aligned and communicated with the locking slide cavity 56, the rope winding motor 77 is started, the rope winding shaft 80 is driven to rotate, the second rope winding wheel 79 is driven to rotate, the third rope 78 is pulled, the pulling slide block 44 is driven to move rightwards, the pulling slide block 44 passes through the locking opening 53 and the locking slide cavity 56 to move rightwards, until the pulling slide block 44 drives the second clamping block 19 upwards, so that the upper end of the second clamping block 19 enters the second clamping groove 16, the key is rotated, so that the lock cylinder 14 is driven to rotate, the rotating friction wheel 17 is driven, and the friction sliding plate 37 is driven to move, thereby pushing the second latch 19 into or out of the door frame, thereby achieving locking and unlocking;
when the wrong key is used, the key cannot enable each locking block 12 to move upwards to the correct position, so that each locking port 53 cannot be communicated with the locking sliding cavity 56 in an aligned mode, and therefore the second clamping block 19 cannot move upwards into the second clamping groove 16, so that when the key is rotated, the key cannot drive the rotating friction wheel 17 to rotate, and cannot enable the friction sliding plate 37 to move to lock a door and unlock a door, at the moment, the motor electromagnet 70 is electrified, so that the motor fixing plate 68 is sucked to the right, the rotating motor 29 is driven to move to the right, the driving shaft 20 is driven to move to the right, the rotating block 33 is driven to move to the right, the sliding clamping column 72 is squeezed into the clamping column sliding cavity 74, the clamping column spring 73 is compressed, the lock cylinder 14 is driven to move to the right, and the key is moved to the whole inside the lock cylinder cavity 11;
the rotation motor 29 is then activated, bringing about the rotation of the drive shaft 20, bringing about the rotation of the rotation block 33 by friction, thereby bringing about the rotation of the rotation connection shaft 26, and consequently the rotation of the lock cylinder 14 to the rear, and simultaneously the displacement of the slider 18 and the lifting block 45, when the rotating block 33 rotates ninety degrees, the sliding clamping column 72 enters the rotating clamping groove 71 under the action of the clamping column spring 73, thereby limiting the rotation of the rotating block 33, the key cavity 13 is opposite to the containing cavity 42, the driving shaft 20 continues to rotate, the first rope winding wheel 21 is carried to rotate, thereby winding up the first pulling rope 30, and thus lifting the lifting block 45 upward, thereby carrying the rotating slider 47 upward, so that the lock slider 52 is carried upward by the second drawing wire 46, so that the lock block 12 is carried upward by the connecting rod 54, so that the locking block 12 does not lock the key and the twitch slide 44 is returned to its original position by the elastic pull cord 55;
meanwhile, the fixture electromagnet 65 is powered off, the first fixture 62 enters the first fixture groove 64 under the action of the fixture spring 61, the driving shaft 20 drives the driving bevel gear 32 to rotate, the driven bevel gear 28 is driven to rotate, the threaded shaft 25 is driven to rotate, the threaded sleeve 23 is driven to move backwards, the ejector block 22 is driven to move backwards, the key is extruded out and falls into the containing cavity 42, the motor rotates reversely, the motor electromagnet 70 is powered off after the ejector block 22 and the locking block 12 recover to the original positions, the motor fixing plate 68 drives the rotating motor 29 to recover to the original positions, the sliding fixture column 72 is separated from the rotating fixture groove 71, the driving shaft 20 drives the lock cylinder 14 to recover to the original positions, then the rotating motor 29 stops, and the owner can take out the containing box 40 from the inside after opening the door, so that the wrong key is taken out;
when someone picks the lock, after the lock is not picked in a short time, the motor electromagnet 70 is electrified, the lock cylinder 14 moves rightwards, and therefore the lock cylinder is locked in the lock cylinder cavity 11, and the lock cylinder cannot be picked.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
