Description
Technical Field
The invention relates to the technical field of lock cylinders, in particular to a blade anti-theft lock cylinder.
Background
The lock is an article which people cannot leave in daily life, and people use the lock to store important articles all the time since ancient times, so that own property cannot be stolen by others. The core anti-theft part of the lock is the lock core, and the performance of the lock core directly influences the anti-theft performance of the whole lockset. At present, lock cylinders are various in types, and the traditional mechanical spring locks and blade lock cylinders are circulated in the market for many years, so that unlocking tools developed by the traditional mechanical spring locks and blade lock cylinders are visible everywhere, and the performance of the lock cylinders can not meet the anti-theft requirements.
In recent years, manufacturers have developed a number of lock cylinders with good performance against this phenomenon. The most representative structure is a side column lock cylinder, in particular a blade side column lock cylinder, and the blade side column lock cylinder has the advantage that the key quantity is much higher than that of a marble side column lock cylinder with the same lock cylinder length. The original blade side column lock cylinder is provided with only one blade in a lock cylinder blade groove (blade storage bin), and is added into two or three blades later, wherein the blade spring acting force of the blade side column lock cylinder is reasonably designed on the oppositely-installed blades, and the other blades moving one blade can move simultaneously, wherein the three blades are more representatively provided with a structure sharing one blade spring, but the structure also has the defects that only two blades are acted by the blade spring when unlocking, and the rest blades are in a springless state, so that the springless blades are very easy to open each other, the technical opening prevention performance is influenced, and the structure has certain quality and potential safety hazard.
