Anti-theft double-system linking lockset device
The invention relates to an anti-theft double-system linking lockset device, in particular to two lock systems being different in structure, adopting correlatively controlled systems and being controlled by one key. The anti-theft double-system linking lockset device comprises a lock body (6), a lock core (2), lockset poking teeth (7) and a key (1). The lock systems, namely an independent blade lock system and an independent spring lock system, are arranged in the lock core in a staggered manner, so as to realize correlative matching and step control of the two lock systems, and further improve the safety of the lockset device. A blade group and a spring group are arranged in a staggered manner at an interval; a correlating pillar is arranged to realize linkage control of the lock systems through the stroke of the key; the secret key grade difference of a blade and a spring is as large as possible, for example, for a safe-guard door lock core of the shortest specification, the diameter of the spring is set to be 2 mm or above, and the secret key grade difference of the spring is set to be 0.8 mm or above, or the thickness of the blade is set to be 1.5 mm or above, and the secret key grade difference of the blade is set to be 2 mm or above, wherein the grade difference values are both higher than like single-body blade lock/spring lock on the market.
