Description

Multi-function electronic puzzle lock for suitcase
The utility model relates to a kind of lock, a kind of multifunctional electronic coded lock that is used on the suitcase of more specifically saying so.
The Chinese patent communique discloses a kind of " double density sign indicating number electronic anti-theft warning box ", the patent No. 92208899.3.It is made up of several parts such as metal cabinet, warning self-lock switch, two cover warning automatic control circuit, two cover mechanical code lock, two cover alarm generator, two cover power supplys.Coded lock is connected with self-lock switch, forms coded lock coupled switch system, and retaining mechanism is dead bolt partly to be added one lock the motion by dead bolt of the latch hook that welds on case and the lower box and realize.And be provided with two and overlap independently warning circuit.The lock of this antitheft newspaper case is to adopt mechanical coded lock, because the restriction of machining accuracy and the wearing and tearing in the use often cause cryptographic function to lose efficacy; In addition, this apparatus structure complexity, poor reliability, the user can not protect and seek stolen chest effectively.
The purpose of this utility model provides a kind of electronic cipher and tele-alarm, the multifunctional hand suitcase electronic password lock that can protect and seek stolen chest effectively simple in structure.
Above-mentioned purpose can realize in the following manner: a kind of multifunctional hand suitcase electronic password lock, mainly include power supply, inductive switch circuit, cryptochannel, language alarm circuit, signal receiving circuit, signal transmission circuit and unlocking apparatus, power supply is at first delivered to the inductive switch circuit, when holding hand electric shock resistance, relay work on it, the late-class circuit power supply is switched on, when opening as cryptochannel, then electric direct electromagnetic switch through cryptochannel, then unlocking apparatus can move, and suitcase can be opened.If cryptochannel does not have open-minded, then electricity is sent to the language alarm circuit and sends the language alarm signal; Signal transmission circuit when work, then signal receiving circuit work, another road power line that power supply is led to warning circuit cuts off, and holds error code and also can not report to the police and make, and its main purpose is suitcase people when oneself unblanking, and also might open mistake.In addition, also be provided with the form switch in the circuit, when other people take chest by mistake, also can send alarm signal, when the suitcase people took chest, the remote control that constitutes with signal transmission circuit led to the dump of warning circuit with power supply earlier, reports to the police and just can not take place.
On the power line that receives warning circuit, also pick out a light warning circuit, it alternately produces by relay control warning circuit and light warning circuit, and adopting the light warning circuit is to make the people who loses chest can find its chest easily hundreds of meters parts.
The utility model compared with prior art has following advantage: adopt the electronic cipher circuit that cryptographic function has been strengthened, set up the inductive switch circuit again, the people that unpacks must bare-handedly unpack can, signal reception, radiating circuit have been set up in addition again, thereby distinguish the owner of chest easily, do not have the people of remote control, even chest is taken away, also can't open chest, unless whole chest has been destroyed.Set up the form switch in the circuit,, will send chimes of doom as long as chest is moved by undesired.Be provided with the light warning circuit, make and be easy to find chest at night.
