Description

Electronic password lock

Technical field

The utility model relates to a kind of lock, especially relates to a kind of to the isostructural improvement of electronic password lock.

Background technology

At present, coded lock comprise lock a door, lock body and the control lock bolt is opened or the password part of locking states, have only by pressing cipher chips input proper password, can open lockset by rotary latch, if the input incorrect cipher, coded lock is in blocking and can not opens.Its weak point is: in case after non-obligee knew password, the input password also can be opened lockset, need to change password.And existing key-type mechanical puzzle lock can not change password when not dismantling lockset, uses inconvenience.Pin tumbler lock body has and can only use key could open the characteristic of lockset by the people that obligee and obligee authorize, be desirable to provide the key that a kind of obligee of having only invests the symbol right, the coded lock that could open when using key operated mechanical cylinder lock and importing proper password simultaneously, and be not dismantle lockset just can change the coded lock of opening password, simultaneously, need user's memory cipher, be interfered easily, theftproof performance is relatively poor.

The patent of existing people's application, " electronic lock breech lock (patent No. is 91207571.6) " by name, this patent disclosure a kind of electromagnet that utilizes low-voltage current control that electronic lock provides to be fixed in the lock housing whether magnetize, be contained in another lock housing the magnet piece in the dead bolt and produce suction or repulsion with burying, make locking bolt realize automatic open and close lock function.Though these product have Electronic Controlization, make structure simpler, it is more reliable to work, operate more convenient,, the security and anti-theft poor-performing.

Someone's patent of applying for again, " spoonful multipurpose electronic lock (patent No. is 96246464.3) " by name, a kind of spoonful multipurpose electronic lock, it is made up of lock body, dead bolt, latch hook, lock core and key.Be characterized in that key is made up of control circuit, spoon core (several password memories), spoon head, battery, lock core by the slotting key in lock core column, the lock core column, in the key contact, back, contact control circuit, lock core column below pin key, lever, equidistantly the permanent magnet on ring, electromagnet, the lever is formed.Some spoon cores in the key of this lock can be corresponding open some locks, realized that a key opens the function of many locks, more safe and reliable, use more convenient, still, complex structure, manufacturing cost is higher, easy-maintaining is not recycled.

Summary of the invention

The utility model mainly is to solve existing in prior technology to need user's memory cipher, is interfered the technical problem of the relatively poor grade of theftproof performance easily.

The utility model has also solved the existing in prior technology complex structure simultaneously, and manufacturing cost is higher, not the technical problem recycled etc. of easy-maintaining.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: electronic password lock, it comprises lock body and key, be provided with key and lock core in the described lock body, and in described key, be provided with some contacts, described contact is connected with the lock core control circuit, it is corresponding with described contact to be provided with contact in the described key, and described contact is connected with power supply.Helping the user does not need memory cipher, and has the effect of password, has improved theftproof performance; Simultaneously simple in structure, manufacturing cost is low, the production efficiency height; Maintenance is recycled easily.

As preferably, described lock core control circuit is: the two poles of the earth of electronic transformer input are connected with 1 contact being provided with in the described key respectively at least; One of described electronic transformer output extremely directly is connected with 1 contact being provided with in the described key at least, another of described electronic transformer output extremely directly is connected with electromagnet, and at least 1 contact that is provided with in the described key directly is connected with electromagnet.When key inserts key, the lock core control circuit will have current flowing, under the effect of electronic transformer, make electromagnet produce magnetic, and magnetized electromagnet will attract the dead bolt that is connected with lock core, thereby play the purpose of unblanking.

As preferably, described contact is at least 4, and the number of described contact is corresponding with the number of described contact.Help forming password, improved theftproof performance, help the simplification of manufacturing process again, reduce manufacturing cost.

As preferably, have at least 2 contacts to be connected with the two poles that is provided with in the described key respectively in the described contact, have at least 2 contacts to be connected in the described other contact by lead.2 contacts are connected the two poles of the earth of power supply, when key inserts key, power supply are provided for the lock core control circuit.

As preferably, the contact that connects described power supply is corresponding with the contact that connects electronic transformer input the two poles of the earth; The contact that lead connects is corresponding with the contact that described electronic transformer circuit of output terminal is connected.When key inserts key, form complete loop for the lock core control circuit.The electronic transformer circuit of output terminal forms complete loop by the contact that lead connects, and helps improving theftproof performance.

Therefore, the utlity model has rational in infrastructurely, manufacture craft is simple, and cost of production is low; Circuit is arranged in the lock body, is difficult for destroyed, safe and reliable, easy to use; Electronic lock and mechanical lock function are bound organically in one, and the password kind between lock and the key is many, characteristics such as the security and anti-theft performance is good.
