Abstract

The invention discloses a mechanical delay anti-theft lock, comprising a protective sleeve, a lock core provided with a crisscross keyhole in the middle part and a clamp spring arranged at the tail end of the lock core. The mechanical delay anti-theft lock is characterized by further comprising a spring bolt, a keyhole sealing device, a mechanical delay mechanism and a lock core locking mechanism which is correspondingly arranged at the tail end of the lock core and used for secondarily locking the lock core; the spring bolt is arranged at the tail end of the lock core by means of the clamp spring; and a long slotted hole with an open end is arranged at the lower part of the spring bolt. The mechanical delay anti-theft lock has the advantages that: if the key inserted into the keyhole is not the right key corresponding to the lock, an ejector rod cannot be pulled out with the removal of the key when the key is pulled out, and the lock core locking mechanism is in a locking state all the time; and only the right key is inserted into the keyhole, the ejector rod is reset, and the lock can be unlocked again, therefore the security performance of a pin tumbler lock is largely improved.

Description

A kind of mechanical delay anti-theft lock

Technical field

The present invention relates to a kind of lockset, particularly a kind of mechanical delay anti-theft lock.

Background technology

Cylinder lock is a kind of lockset of extensive use, and its structure comprises lock body, sheath, lock core, pellet and spring; Its principle is to use the pellet of multiple differing heights to pin lock core, and when insert key in keyhole time, tooth on the key can be pushed to identical height by each pellet, and lock core is just decontroled, and twisting key makes lock core rotation, and realization is unblanked; Because its principle of unblanking is simple, in the situation that there is no key, also there is multiple method of unblanking, when the craftsman that unblanks in the less situation of marble amount only need use safety pin, pellet top to same height can be opened, even when marble amount is more, a kind of master key of circulation also can be opened within a certain period of time easily in the market; So cylinder lock antitheft, becomes lockset industry and is badly in need of the difficult problem solving.
