Description

Theftproof lock and key system thereof

Technical field

The present invention relates to a kind of theftproof lock and key system thereof, particularly Suo keyhole does not expose but is built-in.

Background technology

As everyone knows, various vehicle anti-thefts, house door, window is antitheft, the safety cabinet case is antitheft etc. relates to the person, safeguarding of assets aspect, and lock is a common tool.But because existing mechanical lock lockhole (keyhole) exposes, therefore enough operating spaces are provided, making existing lockset be easy to be inserted lockhole by reamer or screwdriver twists bad core and opens lockset or by technical operation, as tinsel instrument or so-called unlocked by universal key.For fear of since lockhole expose the defective of being brought, in Chinese CN 2526413Y patent disclosure a kind of " theftproof lock and key thereof ", this technology provides a kind of theftproof lock and the key thereof that just can open behind the lockhole that hide.But this formerly technology do not solve the root problem that lockhole exposes, simultaneously, its structure is also complicated, is not easy to manufacture.

Summary of the invention

Main purpose of the present invention provides a kind of theftproof lock and key system thereof, and this system can not expose the lockhole (keyhole) of lockset, but is equivalent to be within the lock body, reduces the operating space of row robber person destruction or skilled unlocking.

For the purpose that realizes that the present invention can not expose the lockhole (keyhole) of lockset, adopt following technical scheme: a kind of theftproof lock and key system thereof, it is characterized in that, the keyhole of theftproof lock is in lock body, key handle becomes L shaped shape with the key bit handle so that the unlatching of lock, and core adopts top lock or turning-bolt lock (market is on sale).

Particularly, can to adopt core be that the mode of top lock or turning-bolt lock realizes in lock of the present invention system;

First kind of mode be with top lock keyhole in the plane that is installed in the lock supporter, rather than with the mounting means of conventional core like that with keyhole towards being installed in and the perpendicular direction in plane of locking supporter (being the surface of keyhole) at the lock supporter.At lock-out state, top lock dead bolt is pushed out and enters in the dead bolt hole; In opening, in the lock housing of lock dead bolt withdrawal top, top lock.

The second way be will push up equally the lock keyhole in the plane that is installed in the lock supporter, rather than with the mounting means of conventional core like that with keyhole towards the perpendicular direction in plane that is installed in Yu lock supporter.At lock-out state, lock dead bolt in top is pushed out, and the dead bolt that is pushed out promotes indirect dead bolt again and enters and reach the locking purpose in the dead bolt hole; In opening, in the lock housing of lock dead bolt withdrawal top, top lock, under the effect of spring, dead bolt is return in the lock supporter indirectly.The advantage of using indirect dead bolt is that indirect dead bolt is born the stressed load between dead bolt and the dead bolt hole, and core does not bear consequent external force, guarantees that core is not fragile.

The third mode be with the turning-bolt lock keyhole in the plane that is installed in the lock supporter, rather than with the mounting means of conventional core like that with keyhole towards the perpendicular direction in plane that is installed in Yu lock supporter.At lock-out state, the turning-bolt lock dead bolt is pushed out; In opening, in its dead bolt withdrawal lock housing.

The 4th kind of mode be equally with the turning-bolt lock keyhole in the plane that is installed in the lock supporter, rather than with the mounting means of conventional core like that with keyhole towards the perpendicular direction in plane that is installed in Yu lock supporter.At lock-out state, dead bolt is pushed out, and the dead bolt that is pushed out promotes indirect dead bolt again and reaches the locking purpose; In opening, in the dead bolt withdrawal lock supporter, under the effect of spring, dead bolt is return in the lock supporter indirectly.

The 5th kind of mode be will push up equally lock or turning-bolt lock keyhole in the plane that is installed in the lock supporter, rather than with the mounting means of conventional core like that with keyhole towards the perpendicular direction in plane that is installed in Yu lock supporter.At lock-out state, dead bolt is pushed out, and reaches the locking purpose; In opening, in the lock housing of top lock dead bolt withdrawal lock or in the supporter of lock.But the structure that is lockable is a U type bar or a chain structure, promptly realizes the U-shape lock that is mainly used in Vehicle locking or the chain lock of common indication.

The 6th kind of mode be will push up equally lock or turning-bolt lock keyhole in the plane that is installed in the lock supporter, rather than with the mounting means of conventional core like that with keyhole towards the perpendicular direction in plane that is installed in Yu lock supporter.At lock-out state, dead bolt is pushed out, and the dead bolt that is pushed out promotes indirect dead bolt again and reaches the locking purpose; In opening, in the lock housing that top lock dead bolt withdrawal is locked or in the supporter of lock, under the effect of spring, dead bolt is return in the lock supporter indirectly.But the structure that is lockable is a U type bar or a chain structure, promptly realizes the U-shape lock that is mainly used in Vehicle locking or the chain lock of common indication.

In order to make lock of the present invention be convenient to open, key is preferably made the L type or is further had the structure of bent angle, is difficult for running into the supporter of lock when key turns is unblanked.

Major advantage of the present invention is the inside of keyhole in lock integral body, plays the effect of hiding keyhole, promptly not directly towards the opener.Therefore, making modes such as reamer or screwdriver or technical operation does not have enough operating spaces to reach the purpose of destroying core easily because of the obstruction of lock body, thereby reaches the purpose of illegal unlatching lock.

Below in conjunction with accompanying drawing theftproof lock of the present invention is described in further detail.
