Specific embodiment
To overcome defect present in existing lockset, meets real needs, design a kind of combined lock core pick-proof lock (such as Fig. 1
~Fig. 4), including shell 1, by screw connection the mounting base 7 in shell 1 and by screw connection it is upper in mounting base 7
It covers, is provided with the rotation lock core 10 that the first lock core 6, the second lock core 8 and top are fixedly connected with locking bolt pull rod 9 in mounting base 7, even
The first lock core 6 for being connected to the first lock core marble 5 and the rotation lock core 10 for being connected with rotation lock core marble 12 are located at the upper of mounting base 7
Lower two sides, the lower section of rotation lock core 10 are fixed with the drive rod 18 that control locking bolt pull rod 9 rotates, stretch out the first lock core 6 of upper cover
It is provided with keyhole on the second lock core 8, flexible lock core track 13 and holding are provided in shell 1 in flexible lock core track 13
On flexible lock core 2, the flexible lock core pellet 3 that can be moved forward and backward and fixed flexible lock core pellet 3 are provided on flexible lock core 2
The tightening device 16 set, flexible lock core pellet 3 can be in close contact with the first lock core marble 5 and rotation lock core marble 12, the first lock
Core 6 is connected with the linkage mechanism 4 that can be in contact with tightening device 16, and linkage mechanism 4 passes through the rotation realization pair with the first lock core 6
The control of tightening device 16, the lower part of the second lock core 8 are fixedly connected with flexible lock core push rod 14, the end of flexible lock core push rod 14
Equipped with the groove 15 for being clamped flexible lock core 2 and for the bayonet mount 17 of fixed conveyor bar 18, the shell of 10 downside of lock core is rotated
The protrusion 11 of restricted 2 sliding distance of flexible lock core is set on body 1；The end of the linkage mechanism 4 is provided with U-lag, tightening
Device 16 is placed in U-lag, and the U-lag of fore-aft travel is in close contact by front inner wall or rear side inner wall and tightening device 16；
Locking bolt pull rod resetting apparatus is provided between the locking bolt pull rod 9 and mounting base 7；The flexible lock core pellet 3 by spring with
Flexible lock core 2 connects.
The working principle of the invention: four lock cores being arranged including two exposed lock cores and two built-in lock cores, the
There are the lockholes to insert key for one lock core 6 and the two exposed lock cores of the second lock core 8.The active lock that can be slided in orbit
Lock core marble 3 on core 2 can upper and lower fore-aft travel, the fore-aft travel of lock core marble 3 has spring, pellet toward extrapolation, activity
Lock core 2 has tightening device 16 above to control the fore-aft travel of lock core marble 3, when the lockhole of the first lock core 6 is inserted into key, key
The number of teeth height of spoon passes through the first lock core marble 5 and is transmitted on flexible lock core 2 that (i.e. the mechanical signal of key passes to flexible lock core
On 2).When the first lock core key rotates clockwise, inner wall pushes tightening dress on rear side of the U-type groove of 4 end of linkage mechanism
16 are set, lock core marble 3 is tightened fixation, and lock core marble 3 replicates the number of teeth height of the first lock core key；When the first lock core is to the inverse time
When needle direction rotates, the U-type groove front inner wall of 4 end of linkage mechanism pulls tightening device 16, and tightening device 16 is resetted, unclamped.
Second lock core 8 is by the mobile flexible lock core 2 of the flexible lock core push rod 14 of end, and lock core marble 3 is by the information of the first lock core key
The lock core marble 12 of rotation lock core 10 is passed to, the biography on bayonet mount 17 and the second lock core 8 that the second lock core 8 passes through end
The torsion of second lock core key is passed to the second lock core 8 by lever 18, rotates the second lock core 8, unlatching or locking for lock.
During unlocking, the first lock core key is inserted into the lockhole of the first lock core 6, and after rotating tightening, the first lock core key
The number of teeth height be transmitted to flexible lock core pellet 3 and be stored on flexible lock core pellet 3；Again to the lockhole of the second lock core 8 of insertion
The second lock core key of interior insertion causes protrusion 11 when certain angle rotationally clockwise to block work due to the presence of protrusion 11
Movable lock core push rod 14 and can not rotate, flexible lock core pellet 3 is contacted with the lock core marble 12 of rotation lock core 10 at this time, and will be movable
Pellet height on lock core marble 3 passes to the lock core marble 12 of rotation lock core 10, while drive rod 18 is located at bayonet mount
Right above 17 bayonets formed；Finally the second lock core key is brought up and is lifted, drive rod 18 is made to be connected to bayonet mount
In 17 bayonets formed, and again rotationally clockwise, rotation lock core 10 is opened, and rotation lock core 10 drives 9 turns of locking bolt pull rod
Dynamic, lockset is opened.Locking process is the inverse process of above-mentioned unlocking process.
Beneficial effects of the present invention: being arranged flexible lock core and rotation lock core inside lock body, and outside can not be seen, can be effective
Pick-proof；Lock core separately disposes, the pellet of two lock cores is kept apart for flexible lock core and rotation, can effectively prevent violence unlocking and skill
Art is unlocked.
Simply changing and replacing for those ordinary skill in the art is all within protection scope of the present invention.
