Abstract

The utility model relates to a keyless safety anti-theft system which is provided with a mechanical coded lock (6) and a lock bolt (8). One side of the mechanical coded lock (6) is provided with an electronic coded lock with a lock tongue (5). The utility model adopts the structure in which the electronic coded lock is interlocked with the mechanical coded lock; the total secret key capacity is more than 10< 15 >, which improves the security of the anti-theft system. Additionally, the double alarm of whistle and language on the spot is adopted in an alarm device.

Description

No key dual-safety anti-theft system

The utility model belongs to key-free lock.

Present various types of safety cabinet is more, and the coded number of the mechanical cylinder lock on the cabinet, mechanical code lock or general electronic lock is that the key capacity is all smaller.Chinese patent 2083615U has proposed a kind of combination type electric mechanical safety lock.This patent has increased the confidentiality and the reliability of safety cabinet like this with the dead bolt of electronic lock lock machine tool cylinder lock.But this lock still needs key, the possibility that has key loss and be replicated, and the key capacity of this patent is not high, easily opens.

The purpose of this utility model provides a kind of no key, dual fail-safe, the burglary-resisting system that the key capacity is high.

Main feature of the present utility model is the electronic password lock that a tongue with lock (5) is arranged in a side of keyless mechanical code lock (6).

The utility model has adopted the structure of electronic password lock and keyless mechanical code lock interlocking, and overall key capacity is more than 1015, and the safety warning device of having strengthened burglary-resisting system greatly adopts on-the-spot siren and the dual warning of external language.Be specially adapted to family, hotel.

Fig. 1 is the burglary-resisting system structure chart.

1 is line bag, the 2nd among the figure, electromagnet, the 3rd, lock, the 4th, guide rail, the 5th, dead bolt, the 6th, mechanical code lock rotating disk, the 7th, cabinet door, the 8th, locking bolt.

Fig. 2 is warning system cabinet figure.

Double insurance of the present utility model is to realize like this, see Fig. 1, correct unblank or close lock cipher to make electronic lock provide the pulse signal in 2 seconds, this signal is received on the line bag 1, the electromagnetic field of line packet generation and electromagnet 2 interaction pulling locks 3 slide in guide rail 4, have only when mechanical code lock and open, and dead bolt (5) just can turn back in the open slot of mechanical code lock rotating disk 6, locking bolt 8 withdraws from doorframe, and Men Caineng opens.Otherwise dead bolt (5) heads on the rotating disk of mechanical code lock.

Dual warning function of the present utility model is to realize like this.The error code alarm signal tilts and the vibration alarming signal is received two silicon controlleds respectively and controlled and extremely go up, the one tunnel be onsite alarming one tunnel for taking alarm outward, onsite alarming is in no electricity and puts the state of keeping under the normal condition.Two controllable silicon conductings simultaneously when alarm signal is arranged, two sound sources are sent alarm signal simultaneously, and external warning circuit also has the break alarm function, has strengthened the safety of safety cabinet and door.

Electronic lock has partly adopted a special chip to install outage password holding circuit additional, the power of alterating and direct current automatic switch-over circuit, and circuit block diagram is seen Fig. 2.
