Abstract

The invention relates to a coded anti-theft lock which comprises a lock cylinder and a key, wherein the lock cylinder comprises an outer lock cylinder and an inner lock cylinder; the outer lock cylinder comprises a coding disk, an outer lock body, an outer lock barrel and an outer pin tumbler mechanism; the inner lock cylinder comprises an inner lock barrel, an inner lock body and an inner pin tumbler mechanism; when locking, a key hole is sealed by the coding plate of the coding disk, so the key can not be inserted into the inner lock barrel from the outer lock barrel; the coding disk is locked by the pin tumbler of the pin tumbler mechanism, so the coding disk can not rotate freely, the key or a master key is blocked by the coding plate of the coding disk from being inserted into the inner lock barrel to improve the anti-theft performance; and when unlocking, the pin tumbler mechanism is opened by the key, so the coding disk can rotate, the coding disk is rotated according to the code position of the key hole of the coding plate, so the key hole of the coding plate is aligned with the key hole of the outer lock barrel and the inner lock barrel, and the key can be inserted into the inner lock barrel from the outer lock barrel to unlock the anti-theft lock.
