Abstract

The utility model relates to an electronic anti-theft alarm lock, particularly an electronic anti-theft alarm lock which can lock a locked object with other objects together. The utility model is characterized in that a mechanical lock composed of more than two lock rings and the locking rings are composed of one part of an electronic alarm circuit. The utility model which is especially suitable for bicycles, motorcycles and the padlocks of travel bags is the replacing product of soft locks and bicycle locks.

Description

Electronic anti-theft alarm lock

The utility model relates to a kind of electronic anti-theft alarming lock, particularly the electronic anti-theft alarming lock that locked object body and other object can be locked together.

The electronic alarm lock of selling all loses the form that locked object sports association can be locked on other object at information publication, on the market.More on the Chinese patent communique for the kind of electronic anti-theft alarming lock, but concentrate on door lock or padlock class, be not reported about having the alarming lock of two above lock ring shapes.

Electronic alarm in lock housing constitutes the utility model by mechanical lock and device, it is characterized in that having at least the lock ring that can constitute closed hoop more than two with lock body, all lock rings all are the component parts of electronic alarm circuit, and to have a lock ring at least be length greater than the toughness of 20cm, conductive rope or chain.One end of the lock ring more than two is fixedly connected on the lock body, the other end can insert in the lock ring patchhole on the lock body, and with the lock ring patchhole in the contact point that is provided with constitute the pair of contact of electronic circuit, in keyhole, be provided with the microswitch of electronic alarm, electronic alarm is by circuits for triggering, alarm signal produces circuit, power amplifier and sounding original paper to be formed, and circuits for triggering are made of a gate at least, and the input of each gate all can be provided with a pair of triggering contact.

Mechanical lock in the lock body is partly the same with traditional mechanical lock, constitute by lock cylinder and its linkage, the number of its linkage is identical with the lock ring number, all can pin lock ring, or the movable end of opening two above lock rings simultaneously, the microswitch that the lock cylinder place is provided with, when lock is in locked position, microswitch is in closed position, after key inserts, during position that lock is in out, microswitch is in the position of disconnection, and set lock ring all is section leads of counterlogic door input circuit in the circuits for triggering in the electronic alarm circuit.When lock was in locked position, the switch of warning circuit was in closed position, circuit working, and when any one lock ring is disconnected, the work of circuits for triggering action circuit by power amplifier and sounding original paper, produces the acoustic signal of reporting to the police.

Advantage of the present utility model is that it not only can pin object, and can lock together by other object, no matter and any one lock ring when destroyed, all send alarm signal, be a kind of well antitheft device.

Accompanying drawing 1 is the utility model structural representation

Accompanying drawing 2 is the utility model lock body internal construction schematic diagram

Accompanying drawing 3 is the utility model warning circuit schematic diagram

Below in conjunction with embodiment the utility model is further described.

Lock body shell by rigidity form 2 half by the riveted joint cylindricality or the cuboid that form, and be provided with the lock core position, lock ring fixed point and patchhole, mechanical lock part is by lock core, cam, connecting rod, lock pin, spring are set up by traditional locks, and will be arranged on lock body inside based on the warning circuit of circuit board, wherein the contact of the input of two gates joins with the fixed end of two lock rings and the contact of lock ring patchhole respectively in the circuits for triggering, makes its lock ring constitute the path of gate input.Microswitch is arranged on the top of lock core keyhole, also just can back down switch when key inserts when putting in place, perhaps is arranged on the lock core hole circumference, when lock core rotates, can open switch, and sounding original paper battery all is contained in the lock body shell.

(1) is that lock body shell (2) is a lock ring in the accompanying drawing, and (3) are the lock ring patchhole, and (4) are key, and (5) are sounding original paper hole, and (6) are circuit board, and (7) are battery, and (8) are the sounding original paper, and (9) are cam, and (10) are linkage; F1, F2, F3 are two input NAND gates in the circuit, available CD4011; D1-D3 can be with 1, N4148; CW9561 is the warning music-integrating block, K switch and lock core interlock, and K disconnects when opening lock with key, and A1, B1, A2, B2, A3, B3 are two terminations of lock ring (body).

Claims

1, a kind of electronic anti-theft alarming lock, it mainly is made of mechanical lock and the electronic alarm that is contained in the lock housing, it is characterized in that it has at least two energy and lock body to constitute the lock ring of closed hoop, and all lock rings all are the ingredients of electronic alarm circuit.

2, electronic safety lock according to claim 1, to it is characterized in that having at least a lock ring be length greater than the toughness of 20cm, and conductive rope or chain.

3, electronic safety lock according to claim 1 is characterized in that an end of lock ring is fixedly connected on the lock body, and the contact point that is provided with in the lock ring patchhole on the lock body and the other end of lock ring constitute the pair of contact of electronic circuit.

4, electronic safety lock according to claim 1 is characterized in that being provided with the microswitch of electronic alarm in keyhole.

5, electronic safety lock according to claim 1 is characterized in that electronic alarm produces circuit, power amplifier and sounding original paper by circuits for triggering, alarm signal and forms.

6, electronic safety lock according to claim 5 is characterized in that circuits for triggering are made of a gate at least, and the input of gate is provided with a pair of triggering contact.
