Abstract
Provided is a theft-proof lock, comprising a lock housing, a fixed lock core, a movable lock core, a return spring and a hoodle. A boss is disposed on the movable lock core. A step indenting inwardly is disposed on the fixed lock core corresponding to the boss. The end face of the movable lock core is in the shape of a polygonal structure. When a key is inserted in the theft-proof lock, the movable lock core can move longitudinally, enabling the lock core and a drive portion to be in a non-contact form, and the lock core will not be linked to the drive portion even under the situation of picking. Before the movable lock core moves longitudinally, the lock housing can lock the movable lock core, and the movable lock core cannot be rotated by force, enhancing the pick-proof performance. The theft-proof lock is good in pick-proof performance.
Description
Technical field
The utility model relates to lockset, specifically is a kind of theftproof lock.
Background technology
The lock of prior art generally comprises lock housing, fixed lock core, flexible lock core, back-moving spring and hoodle, after key inserts, hoodle loses locking action, flexible lock core can rotate in fixed lock core, the said fixing lock core is directly to link to each other with running part, therefore utilizes instrument to rotate flexible lock core by force and can pry open lockset.Above-mentioned lockset exists structural defective.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned lockset, proposes the good theftproof lock of a kind of pick-proof performance.
The purpose of this utility model solves by following technical solution: a kind of theftproof lock, it comprises lock housing, fixed lock core, flexible lock core, back-moving spring and hoodle, it is characterized in that projection is arranged on the flexible lock core, the step that indent is arranged on the fixed lock core corresponding to above-mentioned projection, the end face of flexible lock core is polygonized structure.
Theftproof lock of the present utility model, owing on the flexible lock core projection is arranged, corresponding to above-mentioned projection, the step that indent is arranged on the fixed lock core, after key inserts, flexible lock core can be done longitudinally to move, so that lock core and running part are made the noncontact form, even picking lock and running part do not link yet by force; Because the end face of flexible lock core is polygonized structure, before flexible lock core did not vertically move, lock housing can be pinned flexible lock core, can't rotate flexible lock core by force, had strengthened the performance of pick-proof simultaneously.The key tail end of above-mentioned pick-proof lock is provided with a groove, and lock housing is spacing when vertically moving the back rotation to avoid flexible lock core.Pick-proof lock of the present utility model has the good characteristics of pick-proof performance.
Description of drawings
Fig. 1 is the structural representation of theftproof lock of the present utility model.
Fig. 2 is the structural formula intention of the side of theftproof lock of the present utility model.
