Abstract

The utility model relates to an alarm type thief resistant lock. The radial hole of a lock bladder matched with the lock box is filled with a marble, and the outside end of the marble closely abuts against the keyswitch of delaying alarm circuit. The delaying alarm circuit has a delaying circuit or a counter circuit to make the warning device not work momentarily. If meeting the unlocking of stealing property, the inserting time for the key is prolonged or a plurality of keys insert the lock without opening the lock; the two conditions both can cause alarm.

Description

A kind of alarming type anti-stealing lock

Technical field

The utility model relates to lock, the particularly a kind of lock that can report to the police when unnormal unlocking.

Background technology

Existing alarming type anti-stealing lock can send warning when destructivenesses such as being knocked, turn round sled is opened.Often theft unblanks not use strong destructive mode, pulls out the lane and be to use utensil such as master key to insert in the keyhole.Do to open as long as there are a variety of locksets of time enough all may be pulled out.

Summary of the invention

The purpose of the utility model is to provide a kind of theftproof lock that can report to the police automatically by unnormal unlocking the time.

Theftproof lock described in the utility model comprises rotating lock gall in the dress lock box, is equipped with movably pellet shot from a slingshot in the radial hole that lock gall and lock box are complementary, and the outer end of pellet shot from a slingshot is near the key switch that delays warning circuit.

Delaying to report to the police can be delayed alarm, also can be to calculate to report to the police.Be that key switch passes through delay circuit IC sheet or counting circuit IC sheet and sounding or luminous electric linking to each other of telltale.

Alarming type anti-stealing lock described in the utility model, because pellet shot from a slingshot is directly near key switch, insert key in the keyhole and just can promote pellet shot from a slingshot compressing key switch, delay warning circuit and connect, warning circuit is not warned immediately, if normally unblank, a slotting key just should be finished in the time that delay circuit is set and unblank, and extracts key.If improper unblanking can not perhaps use multiple key repeatedly to insert the key runin at the time drawback lock of setting behind the insertion key, then timing or counting circuit will be connected the utensil warning of warning of luminous or sounding.

Description of drawings

The cross-sectional schematic of the described alarming type anti-stealing lock of Fig. 1.

The specific embodiment

Lock gall 7 is contained in the lock box 1 rotatable, and the rotation of lock gall 7 can be stirred dead bolt 4 telescopic movings.Be equipped with pellet shot from a slingshot 9 in the radial hole that lock gall 7 and lock box 1 are complementary, the outer end of pellet shot from a slingshot 9 is near key switch 8.Key switch 8 can only link to each other with telltale 3 electricity by delay circuit 2 or counting circuit 6 (IC sheet), key switch 8 also can link to each other with telltale 3 electricity by delay circuit 2 in parallel, counting circuit 6, the telltale 3 that accompanying drawing provides is buzzers, and telltale also can be luminous utensil certainly.

The accompanying drawing that present embodiment provides is that lock core 7, battery 5, circuit 2, telltale 3 all are contained in the lock box 1.Certainly introduce external power supply, also telltale 3 can be contained in the appropriate location outside the lock box 1.

Claims

1, a kind of alarming type anti-stealing lock, comprise and be contained in rotary lock gall (7) in the lock box (1), be equipped with movably pellet shot from a slingshot (9) in the radial hole that lock gall (7) and lock box (1) are complementary, it is characterized in that: the outer end of pellet shot from a slingshot (9) is near the key switch that delays warning circuit (8).

2, the described alarming type anti-stealing lock of claim 1 is characterized in that: key switch (8) links to each other with telltale (3) electricity by delay circuit (2) or counting circuit (6).
