One-to-many electronic key and anti-theft lock matched with same

Abstract

The invention provides a one-to-many electronic key and an anti-theft lock matched the same, and belongs to the technical field of electromechanical products. The anti-theft lock comprises a lock cylinder, and the electronic key comprises a cylinder-shaped plug and a locking mechanism disposed in the plug. The locking mechanism comprises a magnetic coil, the lock cylinder comprises an insertion cylinder, and the plug can be inserted in the insertion cylinder. The plug is provided with a plurality of rotating drums, and two wiring contacts are arranged on the outer peripheral surface of each rotating drum. The inner wall of the insertion cylinder is provided with annular control areas corresponding to the rotating drums in a one-to-one correspondence mode. When the key and the lock cylinderare matched, the two wiring contacts on each rotating drum are connected to two conduction contacts on the corresponding control area; two shorting contacts on each set of dummy contacts are respectively connected to two ends of the magnetic coil; when any dummy contact corresponds to the wiring contact, the magnetic coil is in a short circuit state or an open state; each rotating drum is connected to a stem in the rotating mode. The advantage of unlocking the lock in one-to-many mode can be achieved.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and relates to a one-to-many electronic key and an anti-theft lock matched with it. Background technique [0002] Lock is a tool product that people often come into contact with in daily life. It is widely used in all walks of life. With the gradual improvement of people's quality of life, there are more and more locks and keys in the family. It is very inconvenient to lose the key. , It is also very inconvenient to have too many keys. If all the locks in a cluster (such as a family, a hotel, etc.) can be opened with one key, the convenience and practicality of life will be greatly improved. [0003] Existing locks are realized through mechanical structures, and there are also electronic locks, such as fingerprint locks, etc. The existing mechanical locks block the door frame and the door body through the deadbolt, and the thief destroys the door body where the lock cylinder is located...
