Abstract

The invention relates to a universal pickproof and anti-theft pin tumbler lock core, which belongs to a core component matched with finished product locks with various structures, different appearances and different purposes and consists of a lock core, a lock bolt, a lock spring, a pin tumbler, a spring and the like. Various cases or panels are made to be matched with the lock core to be used according to different requirements, a key hole position of the lock core is outwards exposed, a lock cannot be unlocked through inserting a slot type screwdriver or a hard object into a key hole and freely rotating the slot type screwdriver or the hard object by 360 degrees, and the anti-theft performance is good.

Description

General pick-proof and anti-theft lock cylinder

Affiliated technical field

The present invention relates to a kind of lock, particularly general pick-proof and anti-theft lock cylinder.

Background technology

Present known domestic market, the kind of lock is a lot, what wherein the most frequently used people were the most familiar is cylinder lock, although profile is different, structure, purposes have nothing in common with each other, and their common drawback is: insert in the keyhole with Flathead screwdriver or hard objects, firmly rotation, pellet shot from a slingshot is cut off at once, and lock is opened, and loses the function of lock.

Summary of the invention

In order to overcome present domestic market particularly bicycle, electric motor car etc., lock is very general by the stolen phenomenon of sled, car, also has in all kinds of larceny cases, and is most relevant with cylinder lock, the invention provides a kind of improved, general, pick-proof, anti-theft spring lock core.

The technical solution adopted for the present invention to solve the technical problems is:

General pick-proof and anti-theft lock cylinder is made up of lock core, dead bolt, snap, pellet shot from a slingshot, spring, is the general designation that is matched in a core component in various structures, different profile, the different purposes finished product lock.Its composition:

1. lock core is columniform, in keyhole is arranged, above the flank of tooth one side, beat the aperture of several degree of depth unanimities, the pellet shot from a slingshot of the length of packing in hole unanimity, the pellet shot from a slingshot end face flushes with the lock core cylindrical, does not protrude not recessed.

2. the dead bolt inner chamber is hollow cylindrical, end be equipped with unblank, the linkage of locking, on dead bolt one side and the corresponding position of lock core, beat same aperture, adorn series of combination pellet shot from a slingshot different in size in the hole.

3. in a side of tubular snap (or corresponding construction), and beat same aperture on lock core, the dead bolt same position, pellet shot from a slingshot, the spring of dress length unanimity in the hole.The lock core dead bolt of packing into, dead bolt reinstalls assembly in the snap (or corresponding construction).Pellet shot from a slingshot, spring location are radially arranged, have housing face-plate topped outward, expose the keyhole position.

The invention has the beneficial effects as follows:

1. under normal circumstances, lock core, dead bolt, snap relative position are stablized regular.When outer human Flathead screwdriver or hard objects insertion lockhole, revolve three-sixth turn arbitrarily and unblank to have nothing to do, lock is not opened.Have only owner to insert lockhole with key, because the key flank of tooth is deep mixed, releasing pellet shot from a slingshot length also differs, enter in the corresponding hole of dead bolt, the short pellet shot from a slingshot that differs of the corresponding one by one dead bolt borough chief of pin that picture is different in size one by one, pellet shot from a slingshot in the dead bolt is just released equal with outer round surface, dead bolt, snap are separated, lock core, dead bolt fuse.When key rotated, dead bolt rotated synchronously, and the terminal linkage of dead bolt is unblanked.During locking, counter the turning 90 degrees of key extracted, and the spring tension in the snap promotes pellet shot from a slingshot and enters in the dead bolt respective aperture, and snap, dead bolt fuse again, and pellet shot from a slingshot resets once again in the lock core, and the theftproof performance spy is good.

2. general pick-proof and anti-theft lock core is the core component in the finished product lock, can be matched in the lock of various profiles, various structures, realizes that easily standardization, generalization, the seriation of lock industry produced in enormous quantities, reduces cost, ensures the quality of products.

The specific embodiment

In actual production, guarantee lock core (interior), dead bolt (in), concentricity, the aperture unanimity of snap punching, form with the special fixture time processing, or precision concentric with the mould assurance, same footpath, to one group of Kong Eryan, successively pellet shot from a slingshot, the spring of packing into and combine for lock core, dead bolt, snap respectively removes the lock core keyhole position and exposes, and all the other have shell topped.

Claims

1. general pick-proof and anti-theft lock cylinder is the core component that is matched in the different purposes finished products locks of the different profiles of various structures, and lock core is columniform, in keyhole is arranged, above the flank of tooth one side, beat the aperture of several degree of depth unanimities, adorn the pellet shot from a slingshot of length unanimity in the hole; Dead bolt is hollow cylindrical, and end is equipped with that band is unblanked, the linkage of locking, on dead bolt one side and lock core correspondence position, beats same aperture, adorns series of combination pellet shot from a slingshot different in size in the hole; A side and lock core, dead bolt at tubular snap (or corresponding construction) are beaten same aperture on the corresponding position, shoot son, spring in the hole, it is characterized in that: the lock core dead bolt of packing into, the dead bolt snap of packing into has shell (or panel) topped outward.

2. general pick-proof and anti-theft lock cylinder according to claim 1 is characterized in that: during locking, dead bolt, snap fuse, and lock core can freely rotate.
