Title:
BLADE COMBINATION OF LOCK CYLINDER
Document Type and Number:
WIPO Patent Application WO/2018/130230
Kind Code:
A1
Abstract:
A blade combination of a lock cylinder, comprising two or more blades (1), all the blades (1) being provided in the same trough-shaped cavity; the blade combination further comprises a linkage sheet spring (2), the linkage sheet spring (2) being able to act on all the blades (1) of said combination at the same time, each of the blades (1) being provided with a wavelike track (104) which fits the linkage sheet spring (2), the linkage sheet spring (2) being able to act on the wavelike tracks (104) on all the blades (1) at the same time, such that when a certain blade is triggered by an unlocking tool, the linkage sheet spring (2) is necessarily driven to move or rotate together with said blade, and further drives the other blades to move or rotate together. In addition, the blade combination can also be provided with an anti-trigger blade (3) which cannot be driven by a key, and which is also provided with an identical wavelike track (104) that interacts with the linkage sheet spring (2), thereby bringing an interference to the unlocking action of an attacker, increasing the difficulty of technical unlocking.
