Description

Small power consumption motor-driven antidrilling door lock controlled by pellet switch

The utility model belongs to daily necessities, the anti-drilling door lock of a kind of micro energy consumption pellet shot from a slingshot switch control motor-driven.

Door lock is one of requisite articles for use in people's actual life, and dual fail-safe, three insurances, coded lock etc. are of a great variety.Yet present existing various door locks, great majority all are that lock core and lock body all are one, in case lock core is destroyed, is easy to open the door and registers one's residence, theftproof performance is very poor, by retrieval patent documentation and consult interrelated data and still find no and the same or analogous record of the utility model.

The purpose of this utility model provides a kind of lock body and separates setting with lock core, and anti-boring device is set on the lock core, the anti-drilling door lock of micro energy consumption pellet shot from a slingshot switch control motor-driven simple in structure, that theftproof performance is good.

The utility model is realized as follows:

The anti-drilling door lock of micro energy consumption pellet shot from a slingshot switch control motor-driven, mainly by dead bolt 1, dead bolt guide pin bushing 2, moving guide pin bushing 5 is decided guide pin bushing 6, lock rod head 8, motor 9, locking bar 10, banking pin 13, lock core 15 compositions such as grade, lock body separates setting with lock core 15, is fixed with to decide guide pin bushing 6 and dead bolt guide pin bushing 2 on lock body base 14, at the left end of deciding guide pin bushing 6 lock rod head 8 and guide pin bushing 5 is housed, locking bar 10 and dead bolt 1, spring 3 is housed on the locking bar 10, shift fork place at moving guide pin bushing 5 right-hand members is provided with gauge tap 4 accordingly, and motor 9 is housed below dead bolt guide pin bushing 2, on the axle of motor 9 cam 11 is housed, left end at cam 11 is provided with banking pin 13, and spring 12 is equipped with in the lower end of banking pin 13; The right-hand member of lock core 15 is equipped with anti-drilling cap seat 16, and anti-drilling cap 17 is housed in the anti-drilling cap seat 16, dials the bar place at lock core 15 left ends and is provided with toggle switch 18 accordingly, links to each other with lead respectively between gauge tap 4, motor 9, toggle switch 18 and battery pack 20.Closely arrange full steel ball in the inner casing of lock body base 14 and the cavity between the shell.The steel ball of insert on the anti-drilling cap 17, the middle part is provided with the flat hole that key is passed through.

The utility model has the advantages that simple in structurely, open flexiblely that theftproof performance is good, lock core is difficult for drilled bad, and lock core separates with lock body, can prevent effectively that dead bolt from being prized, and energy consumption is little.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of lock body base of the present utility model.

Introduce most preferred embodiment of the present utility model with reference to the accompanying drawings in detail:

As shown in the figure, the utility model is when implementing, dead bolt 1 and locking bar 10 can adopt the dead bolt and the locking bar of existing door lock, the lock body base need increase the shell of a flange, the full one deck steel ball of filling row between shell and backplate, when with brill lock body position, steel ball can be held drill bit and rotate to avoid piercing the destruction lock body with drill bit, thereby play tamper-proof effect, the anti-drilling cap 17 of insert will guarantee and can relatively rotate with anti-drilling cap seat 16 on the lock core 15, anti-drilling cap 17 and lock core 15 relative sides are provided with to contain receives the slideway of steel ball, when when bore boring lock core, hard hat 17 is held drill bit, and steel ball rolled on the surface of lock core 15 anti-drilling cap 17 was rotated with drill bit this moment, can prevent effectively that drill bit from piercing lock core, be provided with one with the corresponding position of keyhole on the door shell 19 and can make key turns circular hole easily.Operating principle of the present utility model is when opening the door, key injected that lock core rotates and drive and dial bar and rotate and make toggle switch 18 closures, circuit is connected starter motor 9, motor drives cam 11 and rotates and stir that banking pin 13 moves downward and moving guide pin bushing 5 breaks away from when rotating, promoting locking bar 10 this moment under the effect of compression spring 3 moves to left and drives dead bolt 1 and withdraw from the dead bolt hole 21 door is opened, when locking bar 10 moves to left, moving guide pin bushing 5 upper shift forks are stirred gauge tap 4 and are opened and make down circuitry, motor 9 quits work, 0.5 can finish the breakdown action of door in second, therefore the electric energy that consumes is very little, and a Battery pack approximately can use about 1 year.
