Abstract

The utility model relates to a multiple function box which is used for the theft prevention for a bicycle. The utility model is composed of a box body 1, a box cover 2 and a lock 3, wherein, the box cover 2 can turn around the edge of the box body 1 to be opened, the box cover 2 and the box body 1 are closed to form a fully sealed box, and the inner part of the box cover 2 is provided with an alarm circuit 5 which is utilized to prevent the theft. The utility model has the advantages of safe article storage and strong theft-preventing performance. Besides, the utility model can make an alarm when other person pushes the bicycle.

Description

Multi-function box for bicycle theft-proof and alarm

The utility model relates to a kind of multi-function case of bicycle anti-theft alarm that is installed in bicycle headstock.

Being installed in the extension case of bicycle headstock at present, generally is not have lid, and some has lid, but lid and extension case all are to make with iron wire, are not totally-enclosed, and do not have anti-theft alarm function.

The purpose of this utility model just provides a kind of fully enclosed can produce chimes of doom, the multi-function case of anti-theft alarm bicycle anti-theft alarm after bicycle is promoted by the stranger.

Solution of the present utility model is such: casing and case lid are made with whole block material, after case lid covers, just constitute the fully enclosed and hang case, and anti-theft warning circuit and loudspeaker are installed in the case lid.Be provided with binary pair RS and time delay circuit in the anti-theft warning circuit, when K switch ₂Push alert locations and lock case lid, behind the switch on switch, if there is the people to promote bicycle continuously after the several seconds, binary pair RS sends signal, sends chimes of doom through time-delay, reminds the car owner to note having people's go-cart, if only move bicycle, then annunciator is not worked.

The utility model has the advantages that the employing full-closed structure, storage safety, the someone promotes bicycle and can report to the police, and anti-theft is strong.

Embodiment of the present utility model is as shown in drawings:

Accompanying drawing 1 is a structural representation

Accompanying drawing 2 is left views

Accompanying drawing 3 is electrical schematic diagrams

Accompanying drawing 4 is structural representations of binary pair RS

The utility model is to be made of casing 1, case lid 2, lock 3, case lid 2 can be opened around the upset of the edge of casing 1, casing 1 and case lid 2 are totally-enclosed, make with whole block material, and anti-theft warning circuit is installed in case lid, loudspeaker 4 are installed in a side of case lid, lock can be locked case lid, and behind the locking case lid, whole chest is a full closeding state, storage had not only been maintained secrecy but also safety, and part 7 is K switch ₂

Warning circuit is to constitute time delay circuit by NE555, and its mouth is connected to by transistor G ₁Be the time delay circuit of core, at transistor G ₁Base stage and ground between binary pair RS is arranged, at transistor G ₁And be serially connected with between the IC with transistor G ₂Be the time delay circuit of core, its principle of work is: connect switch (K ₁.K ₁), there is signal to export by the NE555 time-delay after several seconds from mouth, anti-theft warning circuit 5 is in anti-theft state; Binary pair RS is the swing binary pair, and this moment, during mobile bicycle, binary pair RS swung triggering, produces instantaneous break-make, makes capacitor C under the external force effect ₃, C ₄Charging, after some seconds, when C point current potential drops to certain value, G ₁G is worked as in conducting ₁ON time is greater than G ₂During delay time, G ₂Also conducting triggers IC and sends chimes of doom.If when annunciator pipes warning, stop mobile bicycle, annunciator stops again reporting to the police.Whole warning circuit is contained on the wiring board 5.

Binary pair RS is made of two magnet (12,14) that entangle glass tube 11 and reed (13,16), and reed (13,16) is inserted in the glass tube 11, and two magnet (12,14) homopolarity is relative, and magnet 12 is enclosed within the glass tube 11 removable.When there not being external force to do the time spent, magnet 12 suspends because of magnetic action, and reed (13,16) does not contact, and annunciator is not reported to the police, and does the time spent as external force, and magnet 12 motions destroy magnetic balance, and reed (13,16) contacts, and sends chimes of doom.Binary pair RS is contained in the plastic pipe 10, two ends rubber 9 jam-packs, K switch ₁Be and the lock gang switch, disconnect when unblanking, connect K switch when shutting ₂Be the hand switch that is contained in the case, during installation, only need from box body hole, to tighten and be fixed on bicycle headstock and get final product with bolt.

Claims

1, the multi-function case of a kind of bicycle anti-theft alarm is to be made of casing 1, case lid 2, lock 3, and case lid 2 can be opened around the upset of the edge of casing 1, it is characterized in that case lid 2, casing 1 cover the back for totally-enclosed case, are equipped with anti-theft warning circuit in case lid 2.

2, the multi-function case of bicycle anti-theft alarm according to claim 1 is characterized in that anti-theft warning circuit 5 has a binary pair RS, and binary pair RS is connected on transistor G ₁Base stage and ground between, at transistor G ₁And be serially connected with between the IC by transistor G ₂With resistance (R ₅, R ₆), capacitor C ₅Constitute time delay circuit.

3, according to claim, the multi-function case of described bicycle anti-theft alarm is characterized in that the K switch of anti-theft warning circuit 5 ₁With lock 3 interlocks, loudspeaker 4 are installed in a side of case lid 2.
