Description

Technical Field

[0001] The utility model belongs to the technical field of lock cores, and particularly relates to a floating bead lock core. Background Art

[0002] The anti-theft ability of the existing lock core is mainly reflected by the cooperation between the bullet mechanism and the key tooth pattern part. Experienced illegal lock pickers can use tools to replace the key, resulting in insufficient anti-theft ability. Increasing the number of tooth pattern matching points is one way to improve the anti-theft ability of the lock core. However, due to the limited length of the lock core, it is impossible to effectively increase the number of single-row bullet mechanisms. If bullet mechanisms with different angles are set, since there is only a single bead installation part on the lock shell and the rest of the lock shell is a thin-wall structure, due to the limitation of the structural space, it is not conducive to the design, production, and installation of the pin mechanism.

[0003] Therefore, designing a lock core that is conducive to processing, production, and assembly, can increase the number of tooth pattern matching points, and has different directions is a problem that needs to be solved by the staff in this field. Summary of the Utility Model
