Description
Technical field
The present invention relates to lockset, particularly relate to a kind of anti-twisted anti-prizing type lock with idle running defencive function.
Background technology
Because the lifting of illegal unlocking technique as change the lock core of all kinds of locksets with reamer kind tool strand, just can make lockset opened by illegal under the situation without the lockset original key.Various tops lock, turning-bolt lock and pendulum lock etc. are realized the lockset that opens and closes through rotating torque arbitrarily; Under the destruction of the unlawful violence that receives reamer kind tool strand torque; Can be destroyed and open nearly all inevitably; Wherein, even more serious and general by illegal situation of opening for the turning-bolt lock tool.
In order to solve this technological deficiency, the lockset of multiple idle running protection class has appearred on the market, overcome the problem that existing lockset is illegally opened and destroyed by the twist of reamer kind tool with this.
For example China 99235433.1; 200420071147.1 and No. 200510033242.1 patents; All disclose commentaries on classics tongue or pendulum and locked the lockset of type with idle running defencive function; Turning set in the middle of lockset in these three patent documents all adds between externally lock shell and the lock core, and on this centre turning set, be provided for realizing the locking bolt of lock function; Through transforming the pin fixed structure of the inner pellet shot from a slingshot of lock core; Having when key operated, by pellet shot from a slingshot between lock core and the middle turning set and pin fixed structure the two is being combined as a whole, when key rotation lock core; The two can lock the shell rotation together relatively, and the locking bolt in the middle of can driving on the turning set is realized unblanking.And when receiving the unlawful violence twist, lock core then relatively in the middle of turning set idle running, in the middle of illegally the power of twisting can't drive turning set and on locking bolt realize opening and closing function, can avoid illegal strand sled violence damage tapered end and unblank.
In the prior art; Also be useful on the idle running protection lock body structure of top lock; When normally opening with key, can rotational lock core make dead bolt overhanging or in contract realizing opening and closing function, but when receiving powerful twist violence; Promptly relative its outside lock shell of lock core dallies, and avoids by illegal unlatching with this.
