When unlocking, the effective unlocking part of the key 3 is a fixed twisting key tooth 20 and a group of movable unlocking key teeth 19, one movable unlocking key tooth 19 can unlock one set of locking units 16, and after all the locking units 16 are unlocked, the inner lock cylinder 2 can rotate relative to the outer lock cylinder 1; the hand applies torque to the key twist handle 17 to rotate the key twist handle 17, and then the fixed twist key bit 20 is rotated through the key transmission rod 18, and the fixed twist key bit 20 is inserted into the inner lock cylinder fixed twist key bit insertion groove 9, so that the fixed twist key bit 20 further drives the inner lock cylinder 2 to rotate, and at the moment, the inner lock cylinder 2 can rotate relative to the outer lock cylinder 1.
The invention is further illustrated by the following examples.
When locking, the following four conditions should be satisfied:
condition one: in each set of locking units 16: under the action of the inner lock cylinder upper lock ball spring 11 and the inner lock cylinder anti-theft ball spring 15, ball heads of the inner lock cylinder upper lock ball 10 and the inner lock cylinder anti-theft ball 14 extend into the inner lock cylinder movable unlocking key tooth inserting groove 8, and the outer lock cylinder upper lock ball 12 partially extends into the inner lock cylinder upper lock ball groove 7 under the action of the outer lock cylinder upper lock ball spring 13;
condition II: the inner lock cylinder locking pins 10 of different lock cylinder locking units 16 are positioned in different opening directions of the inner lock cylinder movable unlocking key tooth inserting groove 8 (the drawing is simple and convenient, so all the inner lock cylinder locking pins 10 in the drawing are positioned in the same opening direction of the inner lock cylinder movable unlocking key tooth inserting groove 8), and the safety performance of the lockset can be improved by changing the number of sets (3-10 sets) of the lock cylinder locking units 16 and increasing the opening directions (2-10) of the inner lock cylinder movable unlocking key tooth inserting groove 8;
and (3) a third condition: in general, the lockset is provided with 6 sets of locking units 16, the number of the openings of the movable unlocking key teeth inserting grooves 8 of the inner lock cylinder of each set of locking units 16 is 6, and four tens of thousands of types (6 are arranged in the lockset encryption mode 6 ) Possibly; if the lockset is provided with 10 sets of locking units 16, the number of the openings of the movable unlocking key teeth inserting grooves 8 of the inner lock cylinder of each set of locking units 16 is 10, the lockset has three hundred million encryption modes (10 10 ) Possibly, the lockset has extremely strong encryption performance;
condition four: the magnitude relation of stiffness coefficients of the inner lock cylinder upper lock ball spring 11, the outer lock cylinder upper lock ball spring 13 and the inner lock cylinder anti-theft ball spring 15 is adjusted, so that the force for inserting the key 3 when the inner lock cylinder upper lock ball 10 and the inner lock cylinder anti-theft ball 14 are stirred is equivalent, and the inner lock cylinder upper lock ball 10 and the inner lock cylinder anti-theft ball 14 are difficult to judge by simply depending on the force of inserting the key 3.
When unlocking, the following six conditions should be satisfied:
condition one: in the process of inserting the key 3 into the inner lock cylinder movable unlocking key bit inserting groove 8 and the inner lock cylinder fixed twisting key bit inserting groove 9, the fixed twisting key bit 20 and the movable unlocking key bit 19 are ensured to be inserted in sequence according to the direction (the unlocking direction of a lock), the movable unlocking key bit acting end 21 of the movable unlocking key bit 19 plays a role of stirring the head of the lock cylinder 10 on the inner lock cylinder when unlocking (if the inserting direction is wrong, the movable unlocking key bit acting end 21 stirs the inner lock cylinder anti-theft cylinder 14), and the fixed twisting key bit 20 is fixedly connected with the key torsion handle 17 through the key transmission rod 18 or is in an integrated structure;
condition II: the width of the movable unlocking key teeth 19 is equal to the width of the set of locking units 16, so that the movable unlocking key teeth 19 can unlock only one set of locking units 16;
and (3) a third condition: when the insertion direction of the movable unlocking key bit 19 is correct, the locking unit 16 is under the action of the movable unlocking key bit action end 21 of the key 3, the outer lock cylinder locking pin 12 completely exits the inner lock cylinder locking pin groove 7, and the inner lock cylinder locking pin 10 cannot enter the outer lock cylinder locking pin groove 5 (by strictly controlling the size of related components);
condition four: when the insertion direction of the movable unlocking key bit 19 is wrong, the locking unit 16 stretches into the outer lock cylinder anti-theft ball groove 4 at the ball tail of the inner lock cylinder anti-theft ball 14 under the action of the movable unlocking key bit action end 21 of the key 3, so as to play an additional locking role, and at the moment, the inner lock cylinder anti-theft ball 14 and the outer lock cylinder locking ball 12 together play a locking role in the locking unit 16;
condition five: when all the outer lock core locking pins 12 of the locking unit 16 are completely withdrawn from the inner lock core locking pin grooves 7 (namely, when the mechanical password input is completely correct), the inner lock core 2 can rotate relative to the outer lock core 1, and the lock can be opened, but as long as one set of outer lock core locking pins 12 of the locking unit 16 are not withdrawn from the inner lock core locking pin grooves 7 (namely, the mechanical password input part is wrong), the lock can not be opened;
condition six: when unlocking, a hand applies torque to the key torsion handle 17 to enable the key torsion handle 17 to rotate, the fixed torsion key teeth 20 are rotated through the key transmission rod 18, and the fixed torsion key teeth 20 are inserted into the inner lock cylinder fixed torsion key teeth insertion grooves 9, so that the fixed torsion key teeth 20 further drive the inner lock cylinder 2 to rotate, and at the moment, the inner lock cylinder 2 can rotate relative to the outer lock cylinder 1.
The position of the action end 21 of the movable unlocking key bit is correct to determine whether unlocking can be carried out or not, and the inner lock cylinder 2 can only rotate after unlocking (otherwise, the inner lock cylinder is blocked by the upper lock cylinder pins 12 of the outer lock cylinder or the tail part of the anti-theft pins 14 of the inner lock cylinder stretches into the anti-theft pin groove 4 of the outer lock cylinder to block the inner lock cylinder 2), namely the position of the action end 21 of the movable unlocking key bit is equivalent to a password; before the key 3 is inserted into the inner lock cylinder 2, the position of the action end 21 of the movable unlocking key tooth can rotate, after the key 3 is inserted into the inner lock cylinder 2, the position of the action end 21 of the movable unlocking key tooth is restrained by the inner wall of the lock cylinder, so that the position is fixed and can not rotate any more, and the action end 21 of the movable unlocking key tooth can play a role in stirring the marble 10 of the inner lock cylinder or the marble 14 of the inner lock cylinder.
Because the unlocking key teeth of the matched key are the movable key teeth, whether the unlocking is completely dependent on whether the insertion direction of each key tooth is completely correct or not, after the key 3 is successfully taken out after the unlocking, the movable unlocking key teeth 19 can randomly rotate to disturb the sequence by simply swinging the key 3, so that even if the key is picked up by other people after the key is lost, the other people still cannot open the lockset under the condition that the correct insertion direction of each key tooth is not known, and the lockset has higher safety.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
