Description
The utility model relates to a kind of alarm anti-theft lock, particularly relates to a kind of alarm anti-theft lock with audio frequency warning structure.
Alarm anti-theft lock major part of the prior art is to reach theftproof performance by improving lock core structure, has plenty of the double lock tongue of employing structure, has plenty of the identification of increasing (key) device, have plenty of and locking the increase sensing element, also having some is to adopt a series of control circuit and warning circuit, therefore on frame for movement and circuit structure, all seem quite complicated, make complex manufacturing, production debugging is loaded down with trivial details, poor reliability, and most electric control lock all will consume a large amount of electric energy when the state of alert, cause use cost to increase, very uneconomical, and above anti-theft alarm lock function of use all seems single.
The purpose of this utility model is to avoid weak point of the prior art and provides a kind of and have antitheft effect, can serve as the calling doorbell, and is simple in structure, is convenient to produce, cost is low, reliability height, little power consumption, alarm anti-theft lock easy to use.
The purpose of this utility model can reach by following measure: alarm anti-theft lock includes tapered end parts harmony alarm frequently, constitute but also be provided with door chain and switching control mechanism, door chain one end is connected with the lock pin of tapered end parts, the other end is connected with the control member of switching control mechanism on being located at audible alarm.During use tapered end parts harmony frequency alarm is contained in respectively on door or the frame, just be on the alert after the locking, in case when having the people to push, door is hitched by door chain, only can push open and limit about 4 centimetres narrow slit, simultaneously because the control member of door chain Drawing switch controlling organization is pressed to switch, make switch conduction alarm sounds sound, this moment, owner can observe messenger by narrow slit, being that lock core that the friend then opens the tapered end parts is extracted the lock pin that is connected with door chain and opened the door and welcome the guest in, is that the thief is then frightened away by chimes of doom, indoor nobody the time, chimes of doom can cause neighbours or passerby's attention, and the deterrence robber can't continue crime.
The purpose of this utility model can also reach by following measure: the switching control mechanism of alarm anti-theft lock can be by the slide fastener as control member, guide with slideway, be installed in the switch moving plate on the audible alarm base and be fixed on switch stator formation on this base, slide fastener is packed into, and guide is interior also can be moved along the slideway of guide, also be connected with an end of door chain by its cuff link, guide is fixed on the base of audible alarm by connector, switch moving plate and switch stator are formed switch, be arranged between guide and the base and be positioned under the slideway, its contact is positioned at the vertical side of slideway, and switch moving plate and switch stator electrically connect with the loop of audible alarm respectively.The effect of guide is to allow slide fastener move in its slideway, the pulling slide fastener can the depress switch moving plate when door chain is tightened up, make the contact of its contact and the switch stator turn-on power that joins make audible alarm send chimes of doom, the position-limiting action of slideway end can not unclamp door chain simultaneously, door also just can not open, and prevents from that the robber from stretching into hand to unclamp door chain behind the door; The switch that switch moving plate and switch stator are formed is positioned at below the slideway of guide, its structure as shown in Figure 2, when slide fastener is pulled to ways-end because of the tension force to door chain of pushing, must the depress switch moving plate and connect power supply.
The purpose of this utility model can also reach by following measure: the tapered end parts of alarm anti-theft lock can be pushing away spring, be contained in dead bolt in the dead bolt hole and dead bolt thereof and push away spring and seal piece and link to each other with lock core and the finger that is contained in the finger groove of dead bolt constitutes by lock pin, the lock pedestal with lockhole, the lockhole of packing into.The internal construction of tapered end parts and lock pin lock-out state thereof as shown in Figure 3, when locking, the cone-shaped nose of lock pin is pushed dead bolt compression open and is pushed away spring, tacks the lock tongue slot of lock pin by the waist until dead bolt, makes it and can not withdraw from; As desire to unblank, then insert keyhole with corresponding key, rotation makes the finger on the lock core dial back dead bolt, removes the control to lock pin, and lock pin then is pushed spring and releases lockhole, and then lock is opened again.
The purpose of this utility model can also reach by following measure: switch that the audible alarm of alarm anti-theft lock can be made up of the power supply, switch moving plate and the switch stator that are installed on its base and loudspeaker electrically connect and constitute.Make warning circuit simple, working stability, reliability height can be selected the loudspeaker of acoustic pressure 〉=80dBspl, frequency 450Hz for use.
