Creative combination of lock cylinder magnetic anti-theft shield rotary plate and magnetic head key for obtaining thousands of codes

Abstract

The invention relates to a creative combination of a lock cylinder magnetic anti-theft shield rotary plate and a magnetic head key of any automobile-used lock, door lock, safe lock or safe box lock for obtaining thousands of codes. The conventional lock cylinder magnetic anti-theft shield of the automobile-used lock, the door lock, the safe lock or the safe box lock usually has only four magnetic marbles, and only 24 codes at most; and the lock cylinder magnetic anti-theft shield, which has 6 magnetic marbles, only has 180 codes. The lock cylinder magnetic anti-theft shield, which is researched and designed by the invention, has thousands of codes matched with the combination of the magnetic marbles, the rotary plate and the magnetic head key, so as to effectively reduce the mutual unlocking rate of lock cylinder magnetic anti-theft shields. Moreover, a magnetic blocking plate and a magnetic fixing seat are assembled, fixed, and in interference fit with a key handle through a column-shaped positioning column groove, so as to facilitate mounting and production and greatly reduce the manufacturing cost.

Description

technical field [0001] What the present invention relates to is that various vehicle locks, door locks, safe locks and lock core magnetic anti-theft shield rotating plates and magnetic head keys of safe locks are combined to form thousands of codes. Background technique [0002] There are usually only four magnetic marbles in the lock cylinder magnetic anti-theft shield of various car locks, door locks, safe locks and safe locks, and the effective codes are only 24 at most; the door lock cylinder with six magnetic pins is magnetic The anti-theft shield has only 180 effective codes. The steering lock anti-theft device for motorcycles and mopeds "GB17353-1998" requires no less than 1,000 key combinations for the locking system. As for the key combination codes for other vehicle locks, door locks, safe locks and safe locks Ask for more. Therefore existing various vehicle locks, door locks, safe locks and the combined coding quantity of the lock cylinder magnetic anti-theft sh...

AI Technical Summary

Problems solved by technology

Therefore, the number of combination codes of the lock core magnetic anti-theft shields of existing various car locks, door locks, safe locks and safe locks is too small, the mutual opening rate is very high, and the safety performance is very low.

At the same time, the axis of the magnetic pin and the axis of the lock cylinder are arranged in the same direction as the axis of the lock core. The magnetic pin sealing baffle of the magnetic head key of the lock cylinder magnetic anti-theft shield is pasted on the end of the key handle by adhesive technology, and it is easy to fall off after being exposed to the sun or used for a long time.
