Abstract

The invention discloses a breakage-proof core-changing dual-clutch anti-theft lock which comprises a lock and a key matched with each other, wherein the key is composed of a key handle (29) and a key bit (30); the key handle (29) is connected with the key bit (30); the lock comprises a lock body (33), a lock cylinder (34) and lock protective devices (35); the lock cylinder (34) is mounted in a lock cylinder mounting hole of the lock body (33); the lock protective devices (35) are mounted at the two ends of the lock cylinder (34) and are symmetrically fixed through screws (36). According to the invention, the breakage-proof difficulty is increased, the technical opening is avoided, and 100 % theft prevention is realized.

Description

technical field [0001] The invention relates to an anti-theft lock, in particular to an anti-destructive core-changing double-clutch anti-theft lock. Background technique [0002] As we all know, the anti-theft locks have A-level, B-level, super-B-level, and C-level anti-theft locks. A-level anti-theft lock means that the lock cannot be opened technically within one minute; B-level anti-theft lock means that the lock cannot be technically opened within five minutes; super B-level anti-theft lock means that the lock cannot be opened within 30 minutes; C-level anti-theft lock Lock means that the lock cannot be opened within 270 minutes. Among them, the A-level anti-theft lock has a row of pins, the B-level lock has a double row of pins, and the super B-level lock has a double row of pins and a curved groove. At present, there are very few locks that cannot be opened by technology. The so-called super B-level can only prolong the opening time. Existing anti-theft locks not o...
