Abstract
The utility model relates to a special-shaped cylinder lock, which comprises a lock body (1), a lock core (2), and a key hole (12). The utility model is characterized in that the inner part of a cylinder hole (3) in the lock core (2) is provided with a spring (4) and a special-shaped cylinder (6) with a control slot (5); the inner part of the lock core (2) is provided with a through slot (7) which is vertical to the cylinder hole (3), and the inner part of the through slot (7) is provided with a movable control sheet (8) and a control spring (11); the lock body (1) is provided with an arc hole (9) at the point corresponding to the through slot (7). The utility model can prevent various technical unlocking means opening, and can also prevent various technical unlocking means from tentatively unlocking a cylinder in each cylinder hole. The utility model has the advantages of easy manufacture, good practical performance, high safety, and low cost. The utility model can be used in various occasions which use locks.
Description
The utility model relates to a kind of lockset, particularly a kind of special-shaped cylinder lock.
The present various ball lock heads that use, its structure all is by lock body, lock core, and is made up of many pellet shot from a slingshot groups that lock core marble, lock core marble hole, lock spring, lock marble hole and lock body spring are constituted.The pellet shot from a slingshot group can be one group, also can be many groups, and every group can have many to pellet shot from a slingshot.But operating principle all is identical, and when promptly shutting, lock spring embeds in the lock core marble hole under the effect of lock body spring, and lock core can not freely be rotated.When opening lock, key is inserted lock core, key bit jack-up lock core marble ejects lock core to the lock spring that embeds lock core marble hole just by lock core marble, and the turn key just can drive the lock core rotation again, and lock is opened.Owing to always there is certain clearance between pellet shot from a slingshot and the pellet shot from a slingshot hole, earlier lock core is applied a torsion, make the aperture of every pair of pellet shot from a slingshot produce certain dislocation, and make lock core marble and lock spring produce certain inclination, then each lock core marble is depressed one by one, make by the lock spring of skew and withdraw from lock core marble hole, when pressure disappears, because the effect of lock body spring, lock spring will recover normal condition and upspring to the lock core direction, and the dislocation that produce owing to the aperture this moment, lock spring is withstood by the lock core marble aperture, forms self-locking.When lock spring withdraws from lock core marble hole and by self-locking, the torsion that applies is rotational lock core then, and lock is opened one by one.That is to say,, can adopt the technical unlocking means, the pellet shot from a slingshot in each pellet shot from a slingshot hole is done exploratory unlatching handle the ball lock head of said structure no matter which kind of structure pellet shot from a slingshot is.These class technical unlocking means are very big to the security threat of present various cylinder locks.
The purpose of this utility model is: provide a kind of and not only can prevent various technical unlocking means unlatchings, and can prevent to adopt the technical unlocking means that the pellet shot from a slingshot in each pellet shot from a slingshot hole is made the ball lock head that exploratory unlatching is handled.
Formation of the present utility model: it comprises lock body (1), lock core (2) and keyhole (12); It is characterized in that: one or more pellet shot from a slingshot hole (3) is arranged in the lock core (2), be fixed with spring (4) in the pellet shot from a slingshot hole (3) and the special-shaped pellet shot from a slingshot (6) of being with control flume (5) is housed, have in the lock core (2) and the vertical groove (7) of special-shaped pellet shot from a slingshot (6) in pellet shot from a slingshot hole (3), mobilizable control strip (8) and control spring (11) are housed in the groove (7); The position of going up corresponding groove (7) at lock body (1) has arcuate socket (9).
In the above-mentioned special-shaped cylinder lock, on the described special-shaped pellet shot from a slingshot (6) an empty groove (10) can be arranged.
Compared with the prior art, the utility model is owing to adopt pellet shot from a slingshot in the lock core and the arcuate socket on the lock body is controlled control strip, thereby realize the unlatching and the locking of cylinder lock are controlled, not only can prevent various technical unlocking means unlatchings, and can prevent to adopt the technical unlocking means that the pellet shot from a slingshot in each pellet shot from a slingshot hole is done exploratory unlatching processing.Have the processing of being easy to, Practical Performance is good, high safety, and lower-cost characteristics can be widely used in various with the lock occasion.
Below in conjunction with accompanying drawing the utility model specific embodiment is described in further detail.
Fig. 1 is an organigram of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to view;
Embodiment: formation of the present utility model comprises lock body (1), lock core (2) and the keyhole (12) that general cylinder lock all has; Be characterized in: lock body does not have the pellet shot from a slingshot hole in (1), one or more pellet shot from a slingshot hole (3) is only arranged in lock core (2), be fixed with spring (4) in the pellet shot from a slingshot hole (3) and the special-shaped pellet shot from a slingshot (6) of being with control flume (5) is housed, have in the lock core (2) and the vertical groove (7) of special-shaped pellet shot from a slingshot (6) in pellet shot from a slingshot hole (3), mobilizable control strip (8) and control spring (11) are housed in the groove (7); The position of going up corresponding groove (7) at lock body (1) has arcuate socket (9).
In the above-mentioned special-shaped cylinder lock, on the described special-shaped pellet shot from a slingshot (6) an empty groove (10) can be arranged.
When the utility model is opened, key bit corresponding in the keyhole (1 2) is with special-shaped pellet shot from a slingshot (6) jack-up, control flume (5) on the abnormity pellet shot from a slingshot (6) just in time aligns with control strip (8), this moment turn lock core (2), control strip (8) moves to control flume (5) direction under the effect of the arcuate socket (9) on the lock body (1), withdraw from locking, tapered end is opened.During locking, need lock core (2) is screwed to control flume (5), control strip (8), arcuate socket (9) positions aligning, under the effect of control spring (11), control strip (8) moves to arcuate socket (9) direction, withdraws from control flume (5), stretches into arcuate socket (9).Withdraw from key this moment, is subjected to the effect of spring (4), and special-shaped pellet shot from a slingshot (6) moves downward and enters blocking, i.e. the described state of Fig. 1.Because special-shaped pellet shot from a slingshot (6) in the employing lock core (2) and the arcuate socket (9) on the lock body (1) are controlled control strip (8), thereby realize the unlatching and the locking of cylinder lock are controlled.Must handle all special-shaped pellets shot from a slingshot (6) simultaneously during unlatching, can't do exploratory unlatching to the special-shaped pellet shot from a slingshot (6) in each pellet shot from a slingshot hole with the technical unlocking means and handle.Therefore not only can prevent various technical unlocking means unlatchings, and can prevent to adopt the technical unlocking means that the pellet shot from a slingshot in each pellet shot from a slingshot hole is done exploratory unlatching processing.Empty groove (10) on abnormity pellet shot from a slingshot (6) can increase the judgement difficulty to control flume (5) position, when the pellet shot from a slingshot number more for a long time, will be difficult to judge true and false control flume.
