Novel magnetic mechanical anti-theft lock

Abstract

The invention provides a novel magnetic mechanical anti-theft lock which comprises a wafer type key, a lock core rotor and a lock shell, and the wafer type key comprises a wafer; at least six magnetic blocks are arranged in the wafer, and the lock core rotor is a T-shaped cylinder on the appearance, and matches with the lock shell in a contacting way; a second magnetic spring blind hole and a magnetic spring are arranged in the position where the lock core rotor corresponds to the magnetic blocks, and the magnetic spring and the corresponding magnetic block are mutually repellent in terms of magnetism; an iron spring is respectively arranged in the position where the lock shell corresponds to the magnetic spring, and part of the iron spring convexly extends to the blind hole of the second magnetic spring; the bottom of the iron spring is also connected with a return spring, and the lock core fixing hole accommodates the narrow part of the lock core rotor. As the lock core of the lock has no key hole, destruction by tools such as a bolt driver, a screwdriver and the like can be prevented; besides, the key of the lock can not be easily duplicated, and the lock has multiple anti-theft functions, elegant appearance, strong invisibility and higher security.

Description

【Technical field】 [0001] The utility invention relates to an anti-theft lock, in particular to a novel magnetic mechanical anti-theft lock which is not easily damaged. 【Background technique】 [0002] The tumbler lock is currently the most widely used mechanical lock. However, most of the tumbler locks in circulation in the world are mainly made of copper pins, iron pins or magnetic pins. Most of the pins are matched with the same material properties. Its disadvantage is that it is easy to use a master key to move the pins on the lock cylinder to make the pins be pushed away from the blocking position to unlock in an instant, while the lock core mainly composed of magnetic pins may cause the lock to be unable to be opened or the lock to be used due to the demagnetization of the pins. All keys can be opened, and the exposure of the keyhole also provides convenience for thieves to directly destroy the lock cylinder to a large extent. 【Content of invention】 [0003] The techn...
