Lock core capable of quickly changing lock key and method for quickly changing lock key of lock core

Abstract

The invention provides a lock cylinder capable of rapidly transforming keys, as well as a method for rapidly transforming keys of the lock cylinder. A movable lock core and an adjusting block are arranged in a lock case; the adjusting block is selectively fixed by a fastening piece in the lock case; a plurality of lock bead sets are arranged in the lock case; a plurality of clutch sets are arranged in the lock core; and tooth position plates of the clutch sets are controlled by the adjusting block to clutch corresponding tooth position blocks. When the lock cylinder transforms keys, a user only needs to use a first key to rotate the lock core and the adjusting block, so as to ensure that: after the adjusting block is fixed, by means of the axial movement of lock core reset, the tooth position plates of the clutch sets are driven by a guide part of the adjusting block to make radial movement and to separate from or engage the tooth position blocks; after the first key is pulled out, a second key is inserted to rotate the lock core and the adjusting block, which leads the tooth position plates to engage the tooth position blocks again and resets a tooth position state according to the second key. Therefore, the lock cylinder can rapidly transform the keys through convenient operation without the assistance of other tools.

Description

technical field [0001] The invention relates to a lock core capable of quickly changing keys and a method for quickly changing keys with the lock core. Background technique [0002] The lock cores in traditional locks adopt a structural design in which a set of lock cores corresponds to a single specific key. Therefore, when changing keys, the entire set of lock cores or locks must be replaced together because the original lock cores can no longer be used, resulting in Consumers are unnecessary to waste, and there are disadvantages such as high replacement costs. [0003] For the disadvantage that the traditional lock core does not have the function of changing the key, some people have further designed the lock core structure with the function of changing the key. At present, the lock core with the function of changing the key is known, such as the US 2005 / 0011242 "REKEYABLE LOCK ASSEMBLY" patent application As disclosed in the case, it mainly installs a lock core and a sl...

Problems solved by technology

[0004] However, although the above-mentioned design of the lock core structure can provide a configuration that can change the original structure to meet the new key and achieve the purpose of changing the key, however, the lock core needs to be replaced by the old key and the new key in the operation process of changing the key. In addition, it is necessary to use a tool to assist in releasing the meshing state of the tooth piece and the lock ball before changing the configuration of the lock core. Because this tool is not a part of the lock core, the user must use this additional tool when changing the key , to complete the replacement of old and new keys, which is inconvenient to operate
