Abstract

The utility model relates to an electronic anti-theft door lock, belonging to the field of making locks. The utility model is composed of a lock head, a lock body, a key, and an electric alarm. Two special spring holes are arranged in the lock head, wherein, the inner wall of one spring subsidiary hole is provided with an insulation jacket, which causes a spring and a reset spring to completely insulate from the lock head, and a conducting wire is led out of the reset spring; the lower half part of the other spring hole is provided with an insulation jacket, the lowest spring of the hole is made into a step shape, a contact spring is arranged in the insulation jacket, and one conducting wire is led out of the insulation jacket; two holes form two circuit switches. The tooth corresponding to the position of the completely insulating spring hole of the key is stuck with an insulating sheet. The electronic anti-theft door lock has dual anti-theft functions, namely, the functions of sending alarm and locking a core sheet lock.

Description

Electronic anti-theft door lock

The utility model is a kind of electronic anti-theft door lock, belongs to the lockmaking field.

At present, the kind of door lock is a lot of on the market, but with regard to its essence, is still the lock of traditional form, has just made some change thats in form.Its antitheft effect there is no great raising.

For a kind of door lock of safety and reliability is provided, the utility model spy has proposed a kind of electronic anti-theft door lock.

Electronic anti-theft door lock of the present utility model is made up of tapered end, lock body, key and electronic alarm; In tapered end except that normal pellet shot from a slingshot hole and pellet shot from a slingshot, have two special pellet shot from a slingshot holes in addition, one of them pellet shot from a slingshot hole inwall is equipped with insulation sleeve, and wherein pellet shot from a slingshot and return spring and tapered end are insulated fully, draw a lead from return spring, insulation materials is also wrapped in the lock core periphery of this pellet shot from a slingshot hole correspondence; The latter half in another pellet shot from a slingshot hole is equipped with insulation sleeve, and it is one stepped that this hole is formed, and a pellet shot from a slingshot is also made stairstepping below this Kongzui, and return spring is stuck on the insulation sleeve, a contact spring is housed in insulation sleeve and draws a lead; Side at tapered end is equipped with a self-locking device; Return spring with contact spring on the lead of drawing be combined into a line and be connected on the electromagnet coil on the self-locking device, on the device that receives the report for police service then, lock body and tapered end are communicated with another utmost point of alarm by lead as another utmost point; Key is stained with insulating trip on the tooth corresponding to the place, pellet shot from a slingshot hole of insulating fully.

This electronic anti-theft door lock has dual anti-theft feature, promptly reports to the police and the lock core auto-lock function.When inserting the key naked layer of lock core, key will be connected alarm and self-locking device as conductor.When the key that inserts lock core is isolator, when corresponding tooth with ladder pellet shot from a slingshot hole is long, can makes the ladder pellet shot from a slingshot and contact the spring contact, be communicated with alarm and self-locking device; When key bit is too short, can't open door lock.Thereby can play good antitheft effect.
