By adding a marble lock cylinder, the key amount of the blade lock can be significantly improved, the mutual opening rate can be reduced, and the safety of the blade lock can be improved, assuming that the key amount of the marble lock cylinder is M1, the key amount of the blade lock is M2, and the key amount of the blade lock after adding the marble lock cylinder is M1 × M2 When the inserted key has the corresponding correct blade tooth and the marble tooth, the key can be freely rotated to open the marble lock core and the blade lock, thereby opening the main locking tongue, and the blade lock structure of the invention passes through the blade lock Combined with the marble lock core, the two coding techniques of blade coding and marble coding are used to improve the difficulty of key imitation and technology opening, and increase the safety of the lock. The marble lock cylinders are all prior art.

As a further improvement and supplement to the technical solution, the present invention also adopts the following technical measures.

The marble lock cylinder comprises a lock core sleeve and a lockable core shaft which is freely rotatable therein, and the lock core sleeve has an open mounting hole sleeve on the lower cover positioning column extending from the lower cover, and the upper cover and the lock core sleeve are arranged The positioning hole is fixed by a screw, and the lock core sleeve and the lock core shaft have a plurality of through holes extending in the radial direction and an adjacent marble assembly is built therein, and the marble assembly includes a radial through hole which is externally mounted in the lock core sleeve. The sealing marble, the spring of the marble, the middle marble and the extremely poor marble installed in the radial through hole of the lock core shaft have an axial key hole in the center of the lock core shaft. The combination of a plurality of extremely different types of marbles can greatly increase the key amount of the marble lock cylinder, reduce the mutual opening rate, and improve the overall safety of the lock body. The blade teeth on the key for unlocking match the blades, and the marble teeth and the extremely poor marble components match.

The lock cylinder shaft face is provided with a connecting baffle at one end of the lower cover, and an end face of the other end axially extends to form a stopper, and the connecting baffle has an axial key hole corresponding to the lock core shaft. When the lock cylinder shaft is rotated when unlocking, the stopper at one end of the lock cylinder shaft and the connecting bracket installed at the other end respectively intersect with the blade key holes of the upper and lower covers, blocking most of the gaps outside the key inserted in the center, and blocking Any tool insertion is illegally turned on, and the anti-technology opening effect is better. The blade keyholes on both sides of the lock can be blocked for easy installation, and there is no need to consider the left and right when loading the lock.
