Description
Technical field
The present invention relates to a kind of cylinder lock.
Background technology
The key great majority of the cylinder lock coupling of using at present all are pointed tooths, this key bit changes little, the number of teeth is few, poor stability, a utility model patent that title is " cylinder lock " of applicant's application, the patent No. is 200720177460.7, user's teeth key, and key bit changes greatly, the number of teeth is many, so the safety of lock improves greatly when using, take 10 teeth keys as example, general key tooth depth is 5-6mm, facewidth 4mm, each height of tooth changes at 0.4-0.5mm, and per tooth height change minimum has 10 times, and one group of different key has 1,000,000,000 at least; Special key tooth depth 10mm or make the double cog key, one group of key can have 10,000,000,000,000 at least, so just stop a key and opened the phenomenon of a plurality of locks, but, because the principle of unblanking of this lock is key bit to be pushed pellet and moves to lockset position of coupler, technology unlocking also can open it, and the safety problem of lock is also said and can not be guaranteed.
Summary of the invention
The purpose of this invention is to provide a kind of can not technology unlocking, Follow-up type spring lock that technical security is good.
The objective of the invention is to be realized by following mode:
Follow-up type spring lock, comprise lock core and lock tube, one group of marble hole is arranged at lock core top, pellet is contained in the marble hole, a cavity is arranged in the lock core, it is characterized in that: described cavity left side is the movable axle sleeve of column type opening near lock tube one end, the right side of cavity is a rectangular interdigitated electrode structure guide-track groove, pellet loose slot under relative being in interdigitated electrode structure guide-track groove below, the interdigitated electrode structure guide rail embeds in the interdigitated electrode structure guide-track groove, one group of top flat one end is packed in the movable axle sleeve of column type opening, the other end inserts in the broach of interdigitated electrode structure guide rail, this group top flat is arranged in parallel, the top of interdigitated electrode structure guide rail is a plane, the face that forms with broach meets at right angles, each top flat is fixed return spring on the top of inserting nose of comb, namely going up return spring places under the interdigitated electrode structure guide rail top and the terminal superjacent air space of top flat, lower pellet group sheet below upper return spring with stretch into below the top flat of interdigitated electrode structure guide rail, the end that is top flat is pressed on the lower pellet group sheet, lower pellet group sheet is an integral body, the top of lower pellet group sheet is highly not wait concavo-convex alternate square tooth, 2 to 3 downward column type disjunctor pellets are arranged at the bottom of lower pellet group sheet, lower marble hole is arranged on the lock tube, column type disjunctor pellet on the lower pellet group sheet passes the lower marble hole on the lock core, insert in the lock tube lower marble hole, in the lock tube lower marble hole, bottom-up lower return spring is housed successively, little pellet and lower pellet group sheet column type disjunctor pellet.
The top flat that described this group is arranged in parallel, the top of each top flat all are stub axles, and this stub axle inserts in opening movable moving axis cover, and the end of top flat inserts in the broach of interdigitated electrode structure guide rail, and top flat quantity equates with upper and lower marble amount, and the pellet shape is cylindrical.
The key side of the being tooth of Follow-up type spring lock of the present invention, the number of teeth amount of the tooth of key and lower pellet group sheet, just all identical, differ for convex-concave at the key axle, each jog represents a tooth, concavo-convex position on the key is corresponding with pellet, each tooth of key is set on the circular shaft, spindle nose band point or band eye, every key is wanted the long tooth of 4～5 millimeters of two height at least, this long tooth both had been the power tooth of rotational lock core, when unblanking, behind key turns 90 degree, key bit promotes interdigitated electrode structure guide rail rotational lock core, and lock is namely opened.The number of teeth of every key, namely the concavo-convex number of teeth has 6 at least.
Advantage of the present invention is:
Common spring lock is that key bit pushes pellet and moves to lockset position of coupler, and pellet is outwards mobile, and it can force pellet to move.Follow-up type spring lock is opposite with common spring lock, and pellet moves inward when unblanking.Top flat under the pushing of key bit, the pellet that pushes top (or outwards) upwards (or outwards) mobile, unclamp simultaneously the bottom pellet group of (or inwardly), inwardly follow-up is mobile under the promotion of spring for bottom pellet group, arrives simultaneously lockset position of coupler.The bottom pellet can not be forced mobile.The end of each top flat has a return spring in guide rail inside, be pressed on the lower pellet gear piece.When technology unlocking is provoked a top flat when moving up, even the top pellet reaches lockset position of coupler, unclamp top flat after, the top flat self-return.It is motionless for bottom disjunctor billiards plate.Want to unblank, all top flats must reach lockset position of coupler simultaneously, so the present invention has stopped the possibility of technology unlocking, but the safety that improves lockset.
