Abstract

The utility model relates to an electric alarm lock device which is triggered by making use of the vibration sensing and is composed of a minor box body, a lock head, an alarm circuit and a loud-speaker, etc. A vibrating sensing part is primarily composed of a metal clip with two pieces of arc sheet metal, and a small permanent magnet steel hammer. The standby condition and the reposition of a vibration sensor are controlled by frapping or loosening a reposition rope which is driven by the rotation of a straight shaft connected with a lock core when the lock is unlocked and locked. The utility model has the advantages of small size, portability, agile design, easy concealmen, high sensitivity; in addition, the utility model not only can be used for generally guarding against theft and giving an alarm, but also can be used as a surveillance alarm in the vibratory and tilting situations which are not allowed.

Description

The vibration-type electronic alarm lock

The utility model relates to a kind of electronic warning locking device that utilizes vibration-sensing to trigger.

Warning device of the prior art mainly contains following several control mode: (one) breakpoint formula; (2) induction type; (3) light-operated; (4) contact, though the warning device of these forms is used in people's work and life widely, but still exist certain limitation and shortcoming to some extent, if any laying the time be subjected to limitation of field condition, expose easily, the complex structure that has, cost an arm and a leg etc., need us to come further to improve and replenish.

The purpose of this utility model is exactly a kind of novel electronic alarm lock of developing for the deficiency that overcomes prior art that utilizes vibration-sensing to trigger.

The purpose of this utility model realizes by the following technical solutions, it will trigger and report to the police and partly be lumped together dexterously with the mechanical lock of using always, by a less box body, tapered end, warning circuit, compositions such as loudspeaker, it is characterized in that: the lock core support is fixed on the interior dividing plate of box body, on lock core, be connected with a d-axis, the other end of d-axis is equipped with sheave, when using key rotation lock core, d-axis and sheave will rotate simultaneously, also be fixed with the shock sensor positioning bolt on the dividing plate, spring is housed on the positioning bolt, the skin of spring is an insulation sleeve, be embedded with the metal flexible cord on the insulation sleeve, outer contact with two arc metal plates composition metal clip shape shock sensors, the arc surface of two arc metal plates constitutes the annulus quoit relatively, it in the circular ring metal circle the little steel hammer of a permanent magnet, little steel hammer links to each other hanging on insulation sleeve with the metal flexible cord, with also be drilled with an aperture on the d-axis that lock core links to each other, be fixed with one and control the rope that resets, the control rope that resets passes the locating ring that is fixed on box body bottom and links to each other with the lower end of the little steel hammer of permanent magnet, and the little steel hammer of the installation site of locating ring and permanent magnet is on same vertical center line.

The top of shock sensor positioning bolt is one and regulates bolt, the threaded portion of regulating bolt matches with the screw on two arc metal plate tops, it can regulate the opening and closing of arc metal plate, changes the size in annulus quoit aperture, reaches the purpose of regulating the vibrations trigger sensitivity.

Be distributed with screw hole on sheave, can load onto the control rope of one or more suitable length, the control rope passes from the through wires hole of box body side, constitutes multiple spot control.

The electronic alarm circuit of alarming lock is by a typical astable circuit and sawtooth-wave circuit and loudspeaker, compositions such as battery, three circumscription sockets and function switch in circuit, have been set up, the user can place changeover switch corresponding one grade as required, connect outside source, can obtain just that break alarm, children's are reported urine, newspaper rain, water is opened and function such as daybreak alarm.

According to vibration-type electronic alarm lock of the present utility model, for people's work and life provide a kind of novelty, practical warning device, compare with existing other kind alarm, it is little that it has a volume, being easy to carry, it is hidden to be easy to, be provided with flexibly, advantages such as the amplitude of accommodation is big, and is sensitive reliable, part is combined as a whole dexterously with mechanical lock because it will be reported to the police, the important objects of can packing into inside, after reporting to the police, have only with the key of unblanking and just can remove, otherwise chimes of doom will ceaselessly ring, bring great threat for the theft crime, in burglar alarm, have bigger practical value.

Except that being used for general burglar alarm, also can be used for not allowing shaking significantly and the occasion that tilts is made monitor alarm and used.
