Description

Theft-proof safety cylinder lock

The utility model is a kind of novel pellet shot from a slingshot insurance theftproof lock, is the lock that a kind of vi have high safety, daily life are used.

The cylinder lock set of existing production and use, particularly padlock are because also there are many defectives in the technical pattern imperfection.Existing cylinder lock is made up of lock body, lock core, pellet shot from a slingshot and spring etc., and its principle is to be in diverse location by lock spring and the short pellet shot from a slingshot that differs of this two group leader of lock core marble under spring action.When closed, lock spring inserts between lock body and the lock core under the effect of spring, plays the purpose of fixed lock core; And when opening, key inserts in the lock core hole, acts on lock core marble by the deep mixed roller seating space of key, and the lock body edge is got back on the lock spring top that is inserted between lock body and lock core, thereby makes lock core rotate the purpose that reaches unlatching.Because the lock spring and the lock core marble equal diameters of existing cylinder lock so as long as use a kind of special key, just the pellet shot from a slingshot between lock body and lock core all can be expressed in the lock body, can reach the purpose of unblanking by rotary locking cylinder equally.Thereby broken one key left fixing of a lock.Made the safety lock non insurance.Therefore must transform existing cylinder lock set,, accomplish that really a lock can only be opened by a key, with the person of guaranteeing the country and people masses and the safety of property to remedy the defective of existing cylinder lock.

Task of the present utility model provides a kind of lock of vi have high safety, is a kind of novel pellet shot from a slingshot insurance theftproof lock.

To achieve these goals, solution of the present utility model is: be made up of lock body, lock core, pellet shot from a slingshot and spring etc., it is characterized in that: take forelocking method, the stop bolt pin that between the lock marble hole of existing cylinder lock and hole, adds a cylindrical or square column type, its two ends and lock body are riveted tightly, and intersect vertically with lock marble hole, lock spring is processed into 2/3 large semicircle cylindricality, and its diameter is identical with lock core marble.

The utlity model has following advantage: 1, vi have high safety except that first wife's key, with other mechanical means (not containing destructiveness), all can not reach the purpose of unblanking; 2, simple in structure, processing and easy to use; 3, be applicable to the improved novel anti-theft lockset of various cylinder locks.
