Assembling lock core and assembling lock

Abstract

The present invention discloses a combined lock barrel. It includes first lock barrel, second lock barrel and driving mechanism, the described first lock barrel and second lock barrel are mutually independent; the described second lock barrel can be used for locking and controlling the described first lock barrel; when the described first lock barrel is locked / controlled by second lock barrel, the described first lock barrel can not drive the described driving mechanism to open the lock body; and when the first lock barrel is released by said second lock barrel, the described first lock barrel can be used for driving said driving mechanism to open said lock. Besides, said invention also provides a kind of combined lock.

Description

technical field [0001] The invention relates to a combined lock cylinder and a combined lock. Background technique [0002] At present, most widely used locks adopt a single lock core structure. After the matching key is inserted into the lock core, the lock core can rotate with the key to drive the transmission mechanism to move to open and close the lock body. Because this lock cylinder adopts single lock cylinder structure, it is easy to be opened by illegal users, so safety is difficult to be guaranteed. [0003] In the prior art, there is also a lock body with a double lock cylinder structure. During use, the same key is used to align the stop pin twice to realize the opening and closing of the lock body. See the specific structure figure 1 and specific instructions below. [0004] Application number is 89214724.5, and the Chinese utility model patent that utility model title is " double-core concealed lock cylinder and key " discloses a kind of double-core conceal...

AI Technical Summary

Problems solved by technology

Although the lock core described in this patent has improved the security of the existing lock core to a certain extent, because the two lock cores are "sequentially fitted into one body", the required processing accuracy is higher than that of the lock head of a single lock core.

And because the same key must be used, the security is relatively poor
