Safety lock and key thereof

Abstract

The invention discloses a safety lock and a key thereof. The safety lock comprises a lock body and a lock cylinder, wherein the lock cylinder is provided with a key hole; both sides of the key hole in the lock cylinder are provided with at least one normally closed elastic conductive contact set; an insulating layer is arranged between the conductive contacts and the lock cylinder; the lock body is provided with an electromagnetic bolt device which is matched with a corresponding bolt hole in the lock cylinder; and each conductive contact set is connected with the electromagnetic bolt device through a control circuit. The body of the key matched with the safety lock is provided with an insulating part which corresponds to at least one of the conductive contact sets in the lock cylinder ofthe safety lock. The safety lock is provided with two independent locking mechanisms, namely a mechanical lock and an electronic lock, and the number of the code digits of the lock is permutated and combined according to the cooperation relationship between the spring sets / conductive contact sets and the insulating part of the key; and therefore, the safety lock has a great amount of code digits as compared with a common spring lock, thereby greatly lowering the mutual unlocking rate of the locks. Thus, the invention has better anti-theft performance and higher safety.

Description

technical field [0001] The invention belongs to locks, in particular to a safety lock and a key thereof. Background technique [0002] At present, representative locks include tumbler locks, magnetic locks and electronic locks. Although magnetic locks have high precision, they are easy to demagnetize and gradually withdraw from the market. Electronic locks, although they are modern technology products, are expensive. , and the input method is insufficient, but it is easier to be cracked. Compared with the locks used on the market, most of them are old-fashioned pin locks. The movement of the core, and then the mechanical linkage, controls the movement of the lock bolt. The precision is not high, and it is easy to be cracked by proprietary tools. Contents of the invention [0003] The purpose of the present invention is to provide a safety lock and a key with better anti-theft performance. [0004] The technical solution for realizing the purpose of the present invention ...
