Description

Domestic electronic cipher control lockset security insurance pin

Technical field the utility model relates to a kind of anti-theft device.

The history of background technology lockset is very long, promptly produces wooden lockset in several thousand in the past.Along with the development of society and the raising of productivity, people have created the lockset of unlike material, different performance, different purposes gradually.But, once had with existing lock structure too simply, people are easy to pry open lockset, and its anti-theft effect is relatively poor, all brings potential safety hazard for people's life, work, property etc.

The summary of the invention the purpose of this utility model provides a kind ofly unblanks and installs the domestic electronic cipher control lockset security insurance pin of insurance function to lockset additional by electronic cipher.

The utility model mainly comprises lock housing, lock pin, lock core and lockhole, at the movable installing connecting rods in bottom, lock housing front, in lock pin, offer slot, and offer jack at the positive corresponding slot of lock housing, the corresponding jack position of connecting rod is installed the metal safety plug, and safety plug sees through in the slot of jack insertion lock pin; At lock housing front outside mounting bracket, between support and the lock housing electromagnet is installed, electromagnet is corresponding with the safety plug position, and with connecting rod between be connected by spring; Electromagnet is connected with the electronic cipher circuit, and the button of electronic cipher circuit is arranged on rack surface; Offer open-work in the corresponding lockhole of rack surface position.

When the head of a family unblanks, correctly press password, cryptochannel work, electromagnet produces magnetic, and the safety plug that is fixed on the connecting rod is attracted and extracts out, and delays time 15 seconds, and this time can supply to unblank, and safety plug resets after 15 seconds.When the stranger unblanks, use master key to unblank, even lock core rotates, lock pin also can't be drawn back, door lock is not opened; If think decryption, buttons such as nearly 20 numerals, symbol are arranged on the keyboard, also inconvenience cracks at short notice,

Compared with the prior art, the beneficial effects of the utility model are: by install the safety plug of electronic cipher control additional on lockset, stop any behavior in other people the random inlet chamber, avoid safety problems such as property is lost, personnel's injury.Be fit to be installed on the various security door door locks, make simple, convenient and practical.

The specific embodiment is in elevation of the present utility model shown in Figure 1, mainly comprise lock housing 1, lock pin 2, lock core and lockhole 3, at the movable installing connecting rods 4 in bottom, lock housing front, in lock pin, offer slot, and offer jack at the positive corresponding slot of lock housing, the corresponding jack position of connecting rod is installed metal safety plug 5, and safety plug sees through in the slot of jack insertion lock pin; At lock housing front outside mounting bracket 6, electromagnet 7 is installed between support and the lock housing, electromagnet is corresponding with the safety plug position, and with connecting rod between be connected by spring 8; Electromagnet is connected with the electronic cipher circuit, and the button of electronic cipher circuit is arranged on rack surface; Offer open-work in the corresponding lockhole of rack surface position.

Be described further below in conjunction with Fig. 3 and Fig. 4.

1, the household unblanks: press S3, S4, S5 in order respectively, the electric charge on the C1 is delivered on the C3 through C2, and the base potential of BG1 is raise, conducting, and the 2 pin current potentials of IC reduce, 3 pin output high level, J adhesive.Electromagnet produces magnetic, and the safety plug that is fixed on the connecting rod is attracted and extracts out.Be 15 seconds the discharge time of C3, and this time can supply to unblank, and safety plug resets after 15 seconds.

2, the stranger unblanks: (1) does not press S3, S4, S5 in order, and electric charge just can't be delivered on the C3, and cryptochannel can't be straightened one out and eased out his anxiety.(2) as long as press S1, S2, the electric charge on the C1 just is released, and needs one minute time charging, and in this time, even correctly press password, circuit also can't be straightened one out and eased out his anxiety; (3) as long as press S6, S7, S8, S9, the electric charge on the C6 just is released, and needs one minute time charging, in this time, the base potential of BG2 raises, and D1 is passed through in conducting, the base stage of BG1 is in electronegative potential, even correctly press password, circuit also can't be straightened one out and eased out his anxiety.
