Intelligent burglar-proof lock of safety box

Abstract

The invention discloses an intelligent burglar-proof lock of a safety box, which comprises a key, a lock body, and a panel, wherein the lock is internally provided with a lock cylinder, a main control chip, an electromagnet assembly, an audio alarm and a work power supply, and the key is provide with an IC (integrated circuit) card circuit storing a password, a conductive contact, and a mechanical contact; the lock cylinder is internally provided with a conductive spring and a mechanical spring which are corresponding to the conductive contact and the mechanical contact of the key; the main control chip is internally provided with a CPU (central processing unit) memory which is provided with a password memory for comparing with the password output by the IC card and an unlocking program controller; and the input end of the main control chip is connected with a keyboard for inputting the password, the output end of the main control chip is connected with an unlocking electromagnet assembly and a liquid crystal display screen for displaying the working state of the lock body, and the input end of the main control chip is also connected with a detection circuit for detecting the unlocking working state of an electromagnet. In the invention, an emergency unlocking lock cylinder of an original electronic safety box is removed, a normal unlocking lock cylinder is integrated with the emergency unlocking lock cylinder into a whole, and an emergency IC card password key is added in case of forgetting the password, thereby improving the safety factor of the electronic safety box.

Description

technical field [0001] The electromechanical integrated lockset involved in the present invention is simple and convenient to operate, has a higher safety factor, and is an electronic combination lock that replaces the existing safe. Background technique [0002] my country updated the national standard GB10409-2001 on anti-theft safes in 2001. So far, the locks of electronic combination lock safes have not changed significantly. For a long time, plum blossom keys with low cost have been used as emergency unlocking devices. The electronic combination lock in the safe and the emergency plum key have become the standard configuration of every safe. [0003] As shown in Figure 8, it is the internal structural diagram of the small safe combination lock with the largest sales volume on the market, including a main control board 37, a liquid crystal display 25, an input button 26, an emergency lock cylinder 41, an emergency lock cylinder connecting rod 39, an electromagnetic Iron ...

Problems solved by technology

CN101187272A proposes a mechanical and electronic combination lock controlled by a single-chip microcomputer. Although it proposes that a password and a password memory corresponding to the preset password of the single-chip microcomputer are provided on the key, and corresponding contacts are set on the periphery of the key hole of the lock cylinder, it cannot be used for On the safe, especially it cannot be used for emergency unlocking, its power supply and signal circuit structure is complicated, and it is not suitable for the security combination lock
