Special professional lockset

Abstract

The invention discloses a lockset, in particular to a special professional lockset, which comprises a shell, wherein a main lock core, a main lock tongue, a main lock tongue drive mechanism, a main lock tongue limiting mechanism and a control circuit of the main lock tongue limiting mechanism are arranged inside the shell. The main lock core drives the main lock tongue to move through the main lock tongue drive mechanism so as to realize the opening and the locking of a door, and the main lock tongue limiting mechanism is connected onto the control circuit and limits or allows the movement ofthe lock tongue. The lockset has a simple structure, high reliability, high security performance and low cost; and the mechanical lock is matched with the electronic lock, so the special professionallockset has a double insurance function and is suitable for being popularized in finance and other special industries.

Description

technical field [0001] The invention relates to a lock, in particular to a special professional lock with double insurance functions. Background technique [0002] Currently used locksets include mechanical locks and electronic locks, and there are also a few locksets with electromechanical integration. The above-mentioned locks generally use a single control device, and the opening and closing of the locks are all controlled by a single control, so that the locks are very likely to be stolen when they are in use, which is not conducive to the use of doors in some special industries. For example, bank cash area safety door, vault door, banknote adding room protective door, ATM protective box door, prison door, etc. Because the safety requirements for locks on these doors are particularly high, ordinary locks cannot meet the requirements at all, and traditional mechanical locks must have multiple insurance functions, their structure is complex, bulky, and it is not easy to u...

AI Technical Summary

Problems solved by technology

The above-mentioned locks generally use a single control device, and the opening and closing of the locks are all controlled by a single control, so that the locks are very likely to be stolen when they are in use, which is not conducive to the use of doors in some special industries. For example, bank cash area safety door, vault door, cash deposit room protective door, ATM protective box door, prison door, etc.

Because the safety requirements for locks on these doors are particularly high, ordinary locks cannot meet the requirements at all, and traditional mechanical locks must have multiple insurance functions, their structure is complex, bulky, and it is not easy to use on small doors; Electronic locks are generally controlled by a motor. When the motor is damaged, the electronic lock cannot work normally, which is not conducive to its use and promotion; and the existing locks with electromechanical integration are still immature, especially the locks with multiple insurance functions. Therefore, a lock with high safety performance is required to meet the requirements for locks in the above-mentioned special fields.
