Abstract

The utility model relates to a theft-proof alarm device for a bicycle, which is composed of a sealing box and a delay alarm circuit, wherein the box is composed of a box cover and a box body which are movably connected. A lock sheet is respectively arranged outside the box cover and the box body; the inner part of the box body is provided with a switch triggering the circuit to send alarm in the open position of the box cover; the lower part of the box is provided with a plurality of sound outlet holes of a loud-speaker, and a covering-proof plate; all electronic components of the delay alarm circuit are arranged in the box. The utility model has the advantages of big shell volume and firm shell material, the shell can not be damaged by a thief with a conventional method, and accordingly, the theft-proof performance is good.

Description

The bicycle anti-theft alarm device

Affiliated technical field

The utility model relates to a kind of bicycle anti-theft alarm device, the bicycle anti-theft alarm device of particularly a kind of device on bicycle luggage carrier.

Background technology

Present bicycle is only installed common lockset mostly, does not have warning function, and the thief goes smoothly easily.At the easy stolen situation of bicycle, some bicycle anti-theft alarm devices have been released on the market, all there are some shortcomings in these annunciators, the power of loudspeaker of the annunciator that has is less, and loud speaker is contained in annunciator inside, and the loud speaker phonate hole is located at easily position contacting, the thief covers the loud speaker phonate hole with hand or other body insulations, the warning volume just reduces greatly, and the thief lifts to secluded place to bicycle again with annunciator destruction then, thereby steals bicycle.Some annunciator is by an electronic lock control alarm condition, electronic lock and annunciator internal circuit link, and be emerging in the annunciator outside, the thief just can destroy by the internal circuit of electronic lock with annunciator with high-voltage electric shock, thereby annunciator is damaged and ineffective, the thief also can utilize the electronic lock that is emerging in the outside that the battery in the annunciator is carried out short circuit dischange, and annunciator was lost efficacy, thereby reduces the antitheft effect of annunciator greatly.

Summary of the invention

The bicycle anti-theft alarm device that the purpose of this utility model provides and a kind ofly anti-seals, pick-proof, anti-high-tension current destroy.

The utility model is achieved in that a kind of bicycle anti-theft alarm device, form by a sealed box and delayed alarm circuit, it is characterized in that said box is made up of lid and box body, flexibly connect between lid and the box body, lid and box body external device (ED) have locking plate, the switch that the inherent lid of box body open position device has trigger circuit to report to the police, and the box below has some loud speaker phonate holes, and be provided with and anti-seal baffle plate, whole electronic component devices of delayed alarm circuit are in box.

Described annunciator box body is made with crash-resistant material, and box is installed on the bicycle luggage carrier, or box directly substitutes bicycle luggage carrier.

Described box-shape is flat cuboid.

The utility model enclosure volume is big, and canning material is firm, and the thief can not destroy with conventional approach, so theftproof performance is good.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model cross-sectional schematic;

Fig. 2 is the utility model box body scheme drawing.

1. box bodys in the accompanying drawing, 2. lid, 3. locking plate, 4. the annunciator source switch, 5. lid is opened trigger switch, 6. circuit card, 7. vibration trigger switch, 8. loud speaker, 9. power supply, 10. anti-baffle plate, 11. phonate holes sealed.

The specific embodiment

With reference to Fig. 1, Fig. 2, the utility model is made of a box and delayed alarm circuit, and box is made up of box body 1 and lid 2, and box body 1 adopts hinge to be connected with box body 2, and locking plate 3 is equipped with between box body 1 and the lid 2 in the box outside, can load onto padlock; Cassette interior, be equipped with the switch 4 that trigger circuit are reported to the police in the open position of lid 2, this switch can be used dry-reed tube switch, the below of box has the phonate hole 11 of several loud speakers, and be provided with the anti-baffle plate 10 of sealing, whole elements of warning circuit, promptly circuit card, source switch, power pack, loud speaker etc. all are installed in the box circuit card epoxy sealing.This annunciator box volume does not require to be done very for a short time, do better on the contrary, box can be made the bicycle luggage carrier fixed in shape on shelf or directly replace bicycle luggage carrier, when implementing the utility model, delayed alarm circuit can adopt the common delayed alarm circuit that has vibration and unlatching triggering.Loud speaker can adopt the bigger alarming horn of volume, and source switch is installed on the position that touches easily in the box, and the canning material employing of box is crash-resistant, the material of anti-destruction, as making such as iron plate, stainless steel sheets.

When using the utility model, open the outer tapered end of box earlier, the source switch of the annunciator that closes, warning circuit is started working, and the lid that closes is locked tapered end, because circuit regulates delayed alarm in advance, at this moment close lid and the vibration alarming circuit that produces when locking tapered end can not reported to the police.During alarm work, steal car as thief's attempt, run into car and produce vibration, annunciator is triggered and is reported to the police, and produces high-decibel warning sound, reminds owner, the deterrence thief.Because alarm apparatus is on bicycle luggage carrier, or directly as shelf, and the loudspeaker phonate hole again down, and the outside has anti-ly seals baffle plate and the bicycle rear mudwing is keeping off, and the thief can not cover the loud speaker phonate hole with body insulations such as cloth and stop the loud speaker sound that makes sound; If thief's attempt destroys box or pries open tapered end, turn off source switch, owing to certainly lead to vibration at destructive process, vibration sensor will be triggered and make circuit working send chimes of doom, thief's purpose can not reach.The whole elements of the utility model are installed in the box, and the thief can not destroy electronic circuit with high-tension current.During this alarm work, if owner will drive, must unblank to open the lid, turn off source switch, annunciator meeting at this moment " mistake " is reported to the police, but because owner's proficiency in action, so time of fire alarming is very short.

The utility model static working current has only 200 μ A, very power saving, and No. 1 battery of 8 joints can be used the above time of half a year.

Claims
