Description

A kind of safety anti-theft door and key thereof

Technical field

The utility model belongs to lockset, is specifically related to a kind of safety anti-theft door and key thereof.

Background technology

Current, the representational lockset that uses in the security door comprises several big classes such as cylinder lock, magnetic lock and electronic lock, though magnetic lock precision height, easily demagnetization is withdrawn from the market gradually; And electronic lock though be the modern science and technology product, costs an arm and a leg, and input mode deficiency, easily be cracked all the better, the lockset of Shi Yonging is old-fashioned cylinder lock on the contrary mostly more on the market, and the processing technology of cylinder lock is being updated, antitheft grade improves constantly, but it is to rely on traditional pellet shot from a slingshot to move the action of controlling lock core, and then mechanical linkage, the action of control dead bolt, precision is not high, and very easy broken proprietary instrument cracks.In addition, link complex structure between locking bolt in the security door door leaf and the lockset by mechanical device.

The utility model content

The purpose of this utility model is to provide better safety anti-theft door of a kind of theftproof performance and key thereof.

The technical scheme that realizes the utility model purpose is: safety anti-theft door comprises doorframe, be hinged on door leaf on the doorframe, be located at the lockset on the door leaf, and lockset comprises tapered end, by the dead bolt of tapered end control; Tapered end comprises lock body and the lock core of being located in the lock body, is provided with the pellet shot from a slingshot group in lock body and the lock core, and lock core is provided with keyhole, and the both sides that are positioned at keyhole in described lock core are provided with at least one group of normally closed elastic conduction contact, are provided with insulating layer between conductive contact and the lock core; Described lock body is provided with keyhole corresponding on electromagnetic bolt device and the lock core and matches, and perhaps lockset is provided with protuberance on electromagnetic bolt device and the lock core or corresponding keyhole matches; In addition, match being provided with lockhole corresponding on electromagnetic bolt device and the door leaf on the doorframe, perhaps match being provided with lockhole corresponding on electromagnetic bolt device and the doorframe on the door leaf; The described conductive contact of respectively organizing is connected with described each electromagnetic bolt device by a control circuit.

The utility model comprises also and the supporting key of described safety lock that key comprises the body of establishing tartar, on described body, be provided with described safety lock lock core in respectively organize at least one group of insulation division that conductive contact is corresponding in the conductive contact.

Insulation division on the described key body is to establish through hole on body, and fill insulant constitutes in this through hole, or in the body both sides insulating layer formation is set.

The utility model is to increase by a cover electromagnetic lock pin device on the standard machinery ball lock head, at doorframe or door leaf the electromagnetic lock pin device is set simultaneously, makes tapered end have pellet shot from a slingshot and electromagnetic lock pin device two cover locking mechanisms simultaneously.Its operating principle is, after key inserts lock core, tartar on the key body makes respectively to be organized pellet shot from a slingshot and is in and makes lock core relative to position that lock body rotates, because the electromagnetic lock pin device is with the lock core stop bit, lock core still can not rotate and unblank, at this moment the insulation division on the key body disconnects the normally closed conductive contact of original conducting generation one signal of telecommunication and changes into data signal, detect this data signal and preset password compares by control circuit, conducting electromagnetic lock pin device, the electromagnetic lock pin device is opened, lock core can rotate, and the electromagnetic lock pin device on doorframe or the door leaf is opened.

Conductive contact on the lock core can be provided with as required and organize more, is located at different positions, and supporting with it insulation division on the key then can make up arbitrarily, to form different password combination.

Because tapered end of the present utility model has two and overlaps independently locking mechanism, it is the combination of mechanical lock and electronic lock, the password number of lock carries out permutation and combination by pellet shot from a slingshot group and conductive contact group and on the key insulation division matching relationship, therefore have than the common spring lock many password numbers are arranged, can significantly reduce the mutual opening rate of lock, simultaneously in the small space of lock core, there is not instrument can crack this lockset simultaneously, and the electromagnetic lock pin device that can utilize matched key to control simultaneously on doorframe or the door leaf opens or locking, therefore the utlity model has better theftproof and safety.In addition, the locking bolt in security door door leaf or the doorframe adopts automatically controlled, and does not need mechanical linkage between the lockset, and is simple in structure.

Below in conjunction with drawings and Examples the utility model is described further.
