Description

Anti-theft lock with double-mortise

Technical field

The utility model relates to lockset, especially a kind of anti-theft lock with double-mortise that is widely used in occasions such as family, public institution.

Background technology

Traditional lock generally is the monolock cored structure.This monolock cored structure as long as make lock core be subjected to enough power, makes the hoodle dislocation, just lock can be opened.Therefore the lockset anti-theft capability of this monolock cored structure is relatively poor.

Summary of the invention

The purpose of this utility model is at the relatively poor problem of the lockset anti-theft capability of monolock cored structure, provides a kind of anti-theft capability strong anti-theft lock with double-mortise.

Anti-theft lock with double-mortise described in the utility model comprises tapered end, lock body, outer lock core, internal cylinder, hoodle, flat pearl, spring and key.Lock body and tapered end are connected.Outer lock core is loaded in the macropore of lock body, is rotating with lock body.Internal cylinder is loaded in the blind hole of outer lock core, is rotating with outer lock core.Be equipped with longitudinally the hoodle hole of arranging on lock body, outer lock core, the internal cylinder, and the hoodle hole on the lock body, outer lock core, internal cylinder is corresponding one by one, diameter is identical.The center of internal cylinder is provided with keyhole.Flat pearl of adorning in the hoodle hole on hoodle hole on lock body, outer lock core, the internal cylinder and lock body, outer lock core, the internal cylinder and hoodle can be respectively rows.Two also symmetrical rows.In the hoodle hole on lock body, outer lock core, the internal cylinder flat pearl and hoodle are housed.Flat pearl is loaded in the hoodle hole of lock body, and spring is equipped with in its outside, and by the stopper shutoff.Hoodle is loaded on flat pearl inboard.

When opening lockset, key is inserted keyhole, rotate internal cylinder, hoodle hole on lock body, outer lock core, the internal cylinder radially is on same the straight line, and key can promote hoodle, flat pearl moves outward, makes flat pearl withdraw from outer lock core, outer lock core rotates, and the dead bolt that just can drive tapered end is opened.Key is extracted keyhole, and flat pearl promotes to move up into internal cylinder in the hoodle under spring action, and flat simultaneously pearl inserts outer lock core, and outer lock core can not rotate, and lockset is in the lock state.When lockset is in the lock state, move up into internal cylinder in the hoodle, internal cylinder can arbitrarily be rotated, can not exert all one's strength to hoodle, be impossible so utilize the hoodle dislocation to unblank, therefore, the utlity model has extremely strong anti-theft capability.
