Abstract
The invention discloses a resistance-type anti-theft alarm lock for a bicycle and relates to the technical field of security, overcoming the problem that the lock of the existing bicycle is easily prized up or sheared off and cannot alarm. A plurality of thin steel wires at one end of a wire rope soft connection chain are connected with a raised head of a metal card; the thin steel wires at the end are connected with a conductive plug inside the raised head of the metal card at the same time; a plurality of thin steel wires at the other end of the wire rope soft connection chain are connected with a housing; and the thin steel wires at the end penetrates through the shell to be connected with the first input end of an internal potential detection circuit at the same time, and the raised head of the metal card is locked by the lock after being inserted into the socket concave head of the metal card, and the work power supplies of the potential detection circuit and an audible and visual alarm circuit are switched on at the same time. According to the invention, the audible and visual alarm circuit emits a work audible and visual alarm when the wire rope soft connection chain is sheared off or the raised head of the metal card is prized out from the socket head of the metal card. The resistance-type anti-theft alarm lock for a bicycle has the functions of preventing the short circuit connection of the circuit on the two ends of each thin steel wire in the wire rope soft connection chain by using a lead, and emitting the audible and visual alarm.
Description
Technical field
What the present invention relates to is technical field of burglary prevention.
Background technology
Existing bicycle has brought unlimited convenience and enjoyment to people, but stolen the losing to people of bicycle brought a lot of worries, and existing bicycle lock is easy to just pried open or cut off, and can not report to the police, and the bicycle user is had no way out to this.
Summary of the invention
The purpose of this invention is to provide a kind of resistance-type bicycle anti-theft alarm lock, the present invention is easy to just pried open or cut off the problem that can not report to the police in order to overcome existing bicycle lock.
A kind of resistance-type bicycle anti-theft alarm lock of the present invention, it is made up of the steel rope recessed head of chain, potential detecting circuit, sound light alarming circuit, first rechargeable battery, second rechargeable battery, housing, metal card plush copper, metal card that is flexible coupling;
The said steel rope chain that is flexible coupling is made up of many finer wires, thin constantan wire; Said thin constantan wire external packets is wrapped with insulating barrier, and many finer wires once were enclosed with elastomeric rust proof layer more outside around after being woven in thin constantan wire periphery; Said metal card plush copper set inside has conductive plug; Be flexible coupling many finer wires of chain one end of steel rope are connected with the metal card plush copper, and the thin constantan wire of this end is connected with metal card plush copper in-to-in conductive plug simultaneously; Be flexible coupling many finer wires of the chain other end of steel rope are connected with housing, and the thin constantan wire of this end passes housing and is connected with the first input end of built-in potential testing circuit simultaneously, and the set inside of the recessed head of said metal card has the recessed head of conduction, and is provided with lock; After the metal card plush copper is inserted in the recessed head of metal card and by lock, pin; Connect the working power of potential detecting circuit, sound light alarming circuit simultaneously; Recessed conductive connection of conductive plug and conduction, behind the lock of outwarding winding with key, the metal card plush copper can be thrown off from the recessed head of metal card; And the working power of breaking off potential detecting circuit, sound light alarming circuit; The control output end of potential detecting circuit is connected with the control input end of sound light alarming circuit, and first rechargeable battery is that potential detecting circuit, sound light alarming circuit are once supplied power, and with potential detecting circuit, sound light alarming circuit cure package in housing; Second rechargeable battery is first rechargeable battery, potential detecting circuit, the power supply of sound light alarming circuit secondary through the diode in first rechargeable battery; And first rechargeable battery charged, second rechargeable battery detachably gets off, and charges with universal charger; Said housing can be welded on bicycle crossbeam front end downside, and steel rope is flexible coupling and after chain passes preceding rim the metal card plush copper is inserted in the recessed head of metal card.
The present invention can be when steel rope be flexible coupling that chain is cut off or the metal card plush copper is prized the recessed head from metal card, the sound light alarming circuit work sound and light alarm that set out.It has and prevents with lead the steel rope two ends of thin constantan wire that are flexible coupling in the chain to be carried out short circuit and connected same sound and light alarm.After the externally fed power supply of device is destroyed, do not influence the normal operation of internal power supply yet.Also has advantage simple in structure, with low cost.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present invention.
The specific embodiment
The specific embodiment one: combine Fig. 1 that this embodiment is described, this embodiment is made up of be flexible coupling chain 1, potential detecting circuit 2, sound light alarming circuit 3, first rechargeable battery 4, second rechargeable battery 5, housing 6, metal card plush copper 7, recessed 8 of metal card of steel rope;
The said steel rope chain 1 that is flexible coupling is made up of many finer wire 1-1, thin constantan wire 1-2; Said thin constantan wire 1-2 external packets is wrapped with insulating barrier, and many finer wire 1-1 once were enclosed with elastomeric rust proof layer more outside around after being woven in thin constantan wire 1-2 periphery; Said metal card plush copper 7 set inside have conductive plug 7-1; Be flexible coupling many finer wire 1-1 of chain 1 one ends of steel rope are connected with metal card plush copper 7, and the thin constantan wire 1-2 of this end is connected with metal card plush copper 7 in-to-in conductive plug 7-1 simultaneously; Be flexible coupling many finer wire 1-1 of chain 1 other end of steel rope are connected with housing 6; The thin constantan wire 1-2 of this end of while passes housing 6 and is connected with the first input end of built-in potential testing circuit 2; The set inside that said metal card is recessed 8 has recessed 8-1 of conduction, and is provided with lock 8-2; When metal card plush copper 7 is inserted in recessed 8 of the metal card back and by lock 8-2 pinning; Connect the working power of potential detecting circuit 2, sound light alarming circuit 3 simultaneously; Recessed 8-1 conductive connection of conductive plug 7-1 and conduction, behind the lock 8-2 that outwards winding with key 8-3, metal card plush copper 7 can disengagement from recessed 8 of metal card; And the working power of breaking off potential detecting circuit 2, sound light alarming circuit 3; The control output end of potential detecting circuit 2 is connected with the control input end of sound light alarming circuit 3, and first rechargeable battery 4 is that potential detecting circuit 2, sound light alarming circuit 3 are once supplied power, and with potential detecting circuit 2, sound light alarming circuit 3 cure package in housing 6; Second rechargeable battery 5 is first rechargeable battery 4, potential detecting circuit 2, the power supply of sound light alarming circuit 3 secondaries through the diode 4-1 in first rechargeable battery 4; And first rechargeable battery 4 charged, second rechargeable battery 5 detachably gets off, and charges with universal charger; Said housing 6 can be welded on bicycle crossbeam front end downside, and steel rope is flexible coupling and metal card plush copper 7 is inserted in recessed 8 of the metal card behind the rim before chain 1 passes.
