Electronic spring mechanical lock core double-control safety box

Abstract

The invention relates to an electronic spring mechanical lock core double-control safety box which comprises a lock body, a lock core and a matching key, wherein a mechanical spring and a main control board circuit which are connected with the lock core are arranged in the lock body; the periphery of the lock core is also provided with an electromagnetic spring which is perpendicular to a central axis of the lock core; an electromagnetic coil at the periphery of the electromagnetic spring is connected with the main control board circuit; the main control circuit comprises a single chip microcomputer chip, a data memory and a polarity converting circuit of the electromagnetic coil; the single chip microcomputer chip is used for controlling the polarity converting force of the electromagnetic coil to drive the electromagnetic spring to adsorb or separate from the mechanical lock core; an electromagnet linking mechanism in the safety box has the improvement that the electromagnetic coil drives the electromagnetic spring to move in the lock body for directly controlling the rotation of the lock core; the lock core and the electromagnetic spring for controlling unlocking are tightly combined for reducing the space volume of the lock body in the safety box, and the invention has the advantages of high seal performance, high shock resistance and stable and reliable work; the power consumption of the invention is only one tenth that of a safety box adopting an electromagnet assembly, and the service life of a cell is prolonged; and an emergency unlocking core of the safety box is removed, and a safety system and a security level of the safety box are improved.

Description

technical field [0001] The invention relates to a safe lock, in particular to an electronic and mechanical dual-control safe lock. 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. standard configuration. [0003] As shown in Figure 7, 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 assembly 33, electromagnet connecting piece 40, main dead bolt interlocking bar 31, main lock cylinder 38 etc., these parts are all installed on the safe door. The main lock cylinder 38 is a rotary bolt lock cylinder, which is connected to the deadbolt toggle lever 32 by the transmission rod 27, an...

Problems solved by technology

[0004] The electromagnet usually bounces up by the spring elasticity, because the body is exposed, it is easy to get stuck due to impurities, and is unreliable; at the same time, the electromagnet is easily vibrated by external force and shakes up and down. Opportunity to unlock, there are hidden dangers of illegal unlocking, unsafe

In addition, the electromagnet consumes a lot of power, the working current is not less than 300mA, and the working life of the battery is short
