Gear transmission safe lock emergency opening mechanism

Abstract

The invention discloses an emergency unlocking mechanism for a gear transmission type safe box lock, comprising a gear which is coaxially connected on an emergency lock as well as a guide rack which is meshed with the gear, wherein an electromagnet free of an emergency plectrum is fixed on the guide rack; the guide rack can move along the stretching direction of a core of the electromagnet; the electromagnet is provided with a core shockproof locking mechanism; a locking plate is arranged behind a door sheet of a safe box, is connected with a bolt, and is arranged on the side face of the part of the core extending out of the electromagnet; and when the core moves downward, the locking plate can enable the bolt to advance or retreat under the drive of a knob push rod. The electromagnet provided with the core shockproof locking mechanism is used, the emergency plectrum is canceled, and a method of adopting a gear and rack mechanism to enable the electromagnet to integrally sink is adopted to realize emergency unlocking, so that the condition that the safe box can not be unlocked by shifting the emergency plectrum from the outer side is avoided, and thus the safety is increased.

Description

technical field [0001] The invention relates to a safe lock, in particular to an emergency opening mechanism of a gear transmission type safe lock. Background technique [0002] As far as the existing technology is concerned, electronic safes use electromagnets (also known as electromagnetic valves, electromagnetic coils, solenoids, etc.) ) output door opening signal input is correct, the electromagnet will pull in, and the iron core will retract. At this time, it is the so-called door opening state. The mechanical mechanism that cooperates with the electromagnet can open the door through the rotation of the knob or the cross lock or the blade lock. The electronic safe is equipped with an emergency lock at the same time. In the case of invalid password or power shortage, you need to use the emergency key to open the electromagnet. [0003] Common electromagnets include a new type of electromagnet with an iron core anti-shock locking mechanism, and an emergency pick is desig...

AI Technical Summary

Problems solved by technology

[0003] Common electromagnets include a new type of electromagnet with an iron core anti-shock locking mechanism, and an emergency pick is designed to cover the return spring of the iron core. At present, this kind of emergency opening method is to turn the lock tongue pick by turning the emergency key. , Toggle the emergency paddle on the electromagnet to press down the iron core to achieve, as long as a small hole or gap is destroyed on the safe door panel, or by destroying the electronic lock panel, through the installation hole of the door panel, it can be locked from the outside of the safe door panel. Insert a thin steel wire or a similar fiddle tool, hook it to the position above the electromagnet, and pull down the emergency paddle on the electromagnet coil to open the electromagnet, thereby illegally opening the safe, which has a safety defect
