20150152666 | Lock Core with Different Thicknesses of Lock Plates - A lock core with different thicknesses of lock plates. The lock core has different lock plates with at least two different thicknesses and specifications. The lock plates are arranged in a core body of the lock core so as to greatly increase the permutation/combination number of the security code and reduce the possibility of repetition of the same unlocking code. Also, this increases the difficulty of finding the correct unlocking positions of the respective lock plates, enhancing the security offered by the device. | 06-04-2015 |
