Summary of the invention

To be that a kind of thief of design or the craftsman that unblanks are extremely difficult learn the multilayer anti-theft lock that unlocking technique is opened by own to the purpose of this utility model.

The utility model multilayer anti-theft lock comprises: the internal layer lock core, and the middle level lock core, outer lock body, the middle level lock core can be one deck, or two layers, or three layers, at least one deck.

The internal layer lock core comprises: inner core-body, inner core submissile pin, inner core submissile pin are that a plurality of little pellets shot from a slingshot are formed by stacking, inner core anticreep chute, inner core power transmission shaft, inner core lockhole.

The middle level lock core comprises: middle core body, and SMIS bullet pin, SMIS holds moving axis, the anti-slip slotted eye of SMIS, SMIS power transmission shaft, SMIS pin-and-hole, SMIS sheath.

The lock ectosome comprises: lock body, lock body bullet pin, lock body bullet snap, the anti-core hole of trying to shirk responsibility, anticreep sliding pin, locking kickoff mechanism (common lock has), lock body opening (putting pin, spring, lead sealing).

The advantage of the utility model multilayer anti-theft lock is: the theftproof performance of theftproof performance lock commonly used improves greatly, locksmith and thief can draw out the internal layer lock core, middle level (if a plurality of middle level) is difficult to draw, middle level and lock ectosome let alone draw out, the confidentiality of the lock core of Zeng Jiaing and strick precaution are opened the door by the thief and are stolen the chance of thing crime like this, guarantee the person of resident family and the safety of property.

Antitheft being achieved in that with key of multilayer anti-theft lock inserted in the 1 internal layer lock core hole, push the SMIS bullet pin 8 of inner core submissile pin 4 middle level lock cores, lock body bullet pin 12, lock body spring 13 is moving together, after inner core-body 3 rotates 45 °, inner core-body 3 walls are accepted a SMIS bullet pin 8 and are blocked middle core body bullet pin-and-hole 21, and inner core-body turning cylinder 6 holds moving axis 9 contacts with middle core body simultaneously.Mate as key, then SMIS bullet pin 8 is in the state of freeing with lock body bullet pin 12, be rotated further key 1, inner core-body power transmission shaft 6 drive SMIS hold moving axis and in core body 7 continue rotation, middle core body power transmission shaft 11 rotates the locking kickoff mechanism 19 that drives in the lock body simultaneously and moves to finish and unblank.

Do not match as key 1, then SMIS bullet pin 8 is in the lock state with lock body bullet pin 12, SMIS bullet pin 8 enters lock body bullet pin-and-hole 22, core body 7 is rotated further in stopping, turning cylinder 11 in then can't making on the core body is rotated further, thereby making contracts decides kickoff mechanism 19 and can not finish and free action, and lock is not just opened.
