Abstract
The invention discloses a lock core. The lock core comprises a lock shell, a lock pin (5) and a lock key (1), wherein the lock shell is formed by positioning and fixedly connecting a lock shell outer baffle (2), an upper lock shell (3) and a lower lock shell (4); the lock pin (5) is matched with the lock shell in a straight-line sliding mode; a return spring (12) is connected between the lock pin (5) and the lock shell; a plurality of billiards with the centers on the same straight line and with the same diameter and insurance billiard holes are formed in the upper lock shell (3) and are used for mounting an upper billiard (6), an insurance billiard (8), a billiard spring (9) and an insurance billiard spring (10); a V-shaped groove is formed on the lower lock shell (4) and used for positioning a conical part at the front end of a lower billiard (7) and inserting the key; an insert hole is formed in the lock shell outer baffle (2) and used for inserting the key; billiard holes corresponding to the lock shell billiard holes and with the same diameter as that of the lock shell billiard holes are formed in the lock pin (5) and used for mounting the lower billiard (7); a step (1) for pushing the lock pin (5) is arranged on the key (1); the contact surfaces of the upper billiard (6), the insurance billiard (8), the lower billiard (7) and the lock pin (5) are planes; and the elastic force of the insurance billiard spring (10) is larger than that of the billiard spring (9). The lock core can guarantee normal unlocking or locking, has high burglar-proof performance, and is convenient to use and quick in unlocking.
Description
Technical field
The present invention relates to the mechanical lock field, specifically is a kind of lock core.
Background technology
Anti-theft lock in the market is the elastic force cylinder lock mostly, and screw key is opened lockset behind the insertion key.
But there is following shortcoming in the lock core of above prior art:
1, owing to be that screw key is unblanked, key is torsional deformation easily in use, even fractures, and old man, not too convenient when child opens is also easily through the unlatching of strong destruction property;
2, owing to be that rotation is unblanked, pellet shot from a slingshot needs chamfering, thereby influences precision, reduces theftproof performance;
3, owing to there not being safeties, as long as, lose anti-theft feature just technical unlocking can rotate lockset after starting lock core.
Summary of the invention
The technical problem that the present invention will solve is, provides a kind of can the assurance normally to open or pin, and theftproof performance is good, and is easy to use, open lock core efficiently.
Technical scheme of the present invention is; A kind of lock core of following structure is provided; Lock shell outer baffle (2), the shell of locking (3), lock shell (4) positioning and fixing down and connect to form the lock shell; The shell (3) of locking have a plurality ofly be centered close on the same straight line, pellet shot from a slingshot and insurance pellet shot from a slingshot hole that diameter is identical, be used to install pellet shot from a slingshot (6), insurance pellet shot from a slingshot (8), marble spring (9), insurance marble spring (10), have the V-type groove on the following lock shell (4); Be used for pellet shot from a slingshot (7) nose circle wimble fraction location and insertion key down; Have jack on the lock shell outer baffle (2), be used to insert key, pellet shot from a slingshot hole line of centres vertical plane, V-type groove center line vertical plane and keyhole central vertical face are positioned on the same vertical plane; Lock pin (5) cooperates with lock shell linear slide, between back-moving spring (12) connection is arranged, have on the lock pin (5) with to lock shell pellet shot from a slingshot hole site corresponding, the pellet shot from a slingshot hole that diameter is identical is used to install down pellet shot from a slingshot (7); Key (1) is provided with the step (101) that is used to promote lock pin (5); Last pellet shot from a slingshot (6), insurance pellet shot from a slingshot (8) are the plane with the contact surface of following pellet shot from a slingshot (7), lock pin (5), make that the unlatching precision of lock core is brought up to pellet shot from a slingshot (6), pellet shot from a slingshot (7), insurance pellet shot from a slingshot (8) must be in same plane with lock pin (5) and last pellet shot from a slingshot (6), the contact surface that insures pellet shot from a slingshot (8) down; Insurance pellet shot from a slingshot (8), go up pellet shot from a slingshot (6) bottom with when the last plane parallel of lock pin (5); There is big elastic force poor between insurance marble spring (10) and the marble spring (9); Insurance marble spring (10) elastic force is greater than marble spring (9) elastic force; Can when technical opening, there be big elastic force that insurance pellet shot from a slingshot (8) can be sticked in the pellet shot from a slingshot hole of lock pin (5), effectively prevents technical unlocking;
After adopting above structure, the present invention compares than prior art, has the following advantages:
1, owing to adopt direct-push, insert key after, one push away and not only can open lockset and can also take advantage of a situation and push the door open inward, do not spend screw key, the back key bullet backward of loosing one's grip can be taken advantage of a situation and taken off key, and is convenient, fast, effectively prevented simultaneously through the unlatching of strong destruction property;
2, because the pellet shot from a slingshot contact surface is the plane, make the big raising of unlatching precision of lock, strengthen theftproof performance.
3, because the band safeties make that difficulty improves greatly in the technical opening process, strengthen theftproof performance.
