Description

Anti-theft alarm lock

The utility model relates to a kind of traditional mechanical lock is combined with electronic technology and a kind of novel lockset that constitutes, particularly a kind ofly unblanks or lockset can reliably send the anti-theft alarm lock of alarm signal when wrecking non-owner.

Traditional mechanical lock is generally by lock body, lock core, bolt, link to each other with bolt or with bolt be exactly the formations such as plug of one, plug movable during locking stretches in the lock body.Mechanical lock generally is by key unlocking, but no matter how firm mechanical lock all have by the robber with key or without key open may, and mechanical lock subjects to outside destroy and damages, thereby the antitheft reliability of general mechanical lock is not high.Utility model patent " burglar alarm " (patent No.: also can replenish and enlarge by the scope that practices 93231811.8) in addition.

Task of the present utility model is will provide a kind of to open the lock with the key or do not open the lock with the key and lockset can both send the anti-theft alarm lock of alarm signal when damaging suffering outside destroy reliably non-owner, and alarm signal can be transferred to the appointed place safely.

Task of the present utility model is finished as follows: the plug of bolt and connection bolt or bolt and plug are an overall structure, at the plug affixed isolator of bolt front end dorsad, with the lead of a core tape insulation layer in the inside of bolt plug insulator longitudinally that is the direction that connects of bolt plug insulator pass, preferably pass and be fixed therein at the shaft core line place, an above-mentioned core lead one end passes the external isolator of isolator end and fixes hard conductive bumps of formation with conduction screw or rivet, an above-mentioned core tape insulation layer conductor other end is waited to connect after the bolt other direction passes bolt, in the lock body inside of mechanical lock a resistor R is set, R and lock body insulation, the end of R the conductive bumps of above-mentioned isolator end by the jack correspondence on the lock body in lock body inside, when lockset is closed that is when in the jack on the plug insertion lock body, above-mentioned hard conductive bumps and the corresponding end of R form a good electrical contact point, utilize lead from lock body, to draw the other end of R, the leading-out terminal at this exit and above-mentioned bolt place utilizes twin-core to be directed to the input of the desired warning device detecting unit of above-mentioned utility model patent " burglar alarm ", constitute anti-theft alarm lock thus, above-mentioned lock body bolt plug is made by firm material.One core tape insulation layer conductor being set in above-mentioned bolt plug insulator and isolator is set in the plug termination all is in order to prevent that bolt is by sawed-off or can not utilize other conductor to overlap separated two sections galvanic circles that keep by an above-mentioned core lead and resistor R when cutting off.

Fig. 1 is a kind of concrete lock structure longitudinal sectional drawing of the utility model and vertical view.

Fig. 2 is the basic circuit diagram of warning device of the present utility model.

With reference to Fig. 1, lock body (1) is the firm housing that is made of metal, lock core (2) is the lock core of common mechanical lockset, be used for locking and open lockset, bolt (3) and the plug that is connected bolt (3) (4) or bolt (3) and plug (4) are exactly an overall structure, also be to make by firm metal, bolt (3) is made by hard metal rod, also can be to make by the multiply finer wire is stranded, at the plug affixed isolator of front end (5) of bolt dorsad, be the isolator that insulating resin is done for example, isolator (5) is moulded casting and is embedded in the mode on the plug or connects by the Luo line with can adopting being connected of plug (4), with the lead (6) of a core tape insulation layer at above-mentioned bolt, plug, the inside of isolator longitudinally that is bolt, plug, the direction that isolator is connected is passed preferably and is passed and be fixed therein at its shaft core line place, can do a through hole at its longitudinal axis heart yearn place for the bolt that hard metal rod is made, lead (6) is laid in wherein, for can be stranded in wherein as one finer wire lead (6) by the stranded bolt of making of multiply finer wire, but to be exposed to the outside scarcely, lead (6) can utilize copper screw or copper rivet fixing cord (6) termination to form a hard conductive bumps in the end of isolator (5) at isolator (5) place of passing, the other end of lead (6) is waited to connect after the other direction of bolt passes, go up jack (7) corresponding in addition at lock body (1) with plug (4), one resistor R is arranged on R and lock body (1) insulation in the lock body (1), the end (8) of R faces the hard conductive bumps of isolator (5) end by jack (7) in lock body, for making contact good, the mode that R installs in lock body (1) is fixed on R (8) end on the middle isolator (9) of lock body (1) by copper screw or copper rivet, also form in the outer face of isolator (9) one with the hard corresponding conductive bumps of conductive bumps in above-mentioned isolator (5) end, be located in the hole of isolator (9) in lock body (1) that the compression by spring has elasticity on the spring, resistor R can encapsulate to guarantee insulating properties with flexible plastic tube, the other end of resistor R is drawn from lock body (1) with lead, the leading-out terminal that this leading-out terminal and bolt (4) above-mentioned to be connect are located can be established plugs and sockets in the middle of utilizing duplex wire, guide to the input of the desired warning device detecting unit of above-mentioned utility model " burglar alarm ", constitute anti-theft alarm lock thus, the circuit theory diagrams of warning device are referring to Fig. 2.

The lockset locking, the power switch of closed warning device promptly enters the state of alert during use, and warning device is located at the place of appointment, as in owner's the family or operator on duty place, when non-owner unblanks or lockset when being destroyed, warning device sends chimes of doom in the time of can reaching duration, until messenger's power cutoff.
