Description

Anti-theft alarm lock

The utility model relates to a kind of lock, especially relates to a kind of anti-theft alarm lock.

The various aspects that are locked in people's life at present are used widely, although because the purposes difference of lock, its shape and structure are also different, and lock is made of metal, and the anti-theft capability that has with the firm intensity of its mechanical part itself.Adopt the instrument of combination pliers and so on to damage under the parts situation of lock the thief, lock has just lost its function, and in order to overcome this defective of existing lock, the applicant succeeds in developing a kind of lock with anti-theft alarm function through permanent research.

Order of the present utility model is in a kind of lock that can burglar alarm is provided.

The purpose of this utility model realizes in the following manner, lock of the present utility model is made up of a kind of improved lock and battery case, its improved lock is by lock body 7, lock core 6 and plectrum 2 are formed (Fig. 1), with general phase-locked ratio, the difference of its improved lock only is that plectrum 2 has three to dial tongue 2a, 2b, 2c (Fig. 5), and 2a, 2c and 2b dial tongue and are vertical configuration, when lock is in the lock state, dialling tongue 2a is in the low groove of dead bolt, dialling tongue 2c is in the battery case wall groove, dial tongue 2b and be among the trigger switch, and put through trigger switch, be about to a switch connection in the control circuit system.(Fig. 1) formed in battery case 3, box body 8, spring 9, loudspeaker 10, MX-01 type IC sheet 11, vibroswitch 12, extension spring 13.Compare with general battery case, battery case difference of the present utility model is that lid and box body couple together by extension spring 13, and loudspeaker 10, MX-01 type IC sheet 11, vibroswitch 12, extension spring 13 are installed on the box body.Because the place difference that lock uses, the shape and the size of lock can be very inequality, so these parts can be according to the space flexible arrangement of box body, promptly shape and the size according to box body places any position in the box, just loudspeaker 10, MX-01 type IC sheet 11, vibroswitch 12, trigger switch 1, battery 14 are composed in series a circuit, as coupling together according to Fig. 4 circuit diagram.The employed loudspeaker 10 of the utility model, MX-01 type IC sheet 11, vibroswitch 12, trigger switch 1 all are product solds in the market.When lock is in the lock state, because of trigger switch is in conducting state, when being made the vibroswitch conducting in case the object of being locked vibrates, the foregoing circuit conducting, electric current in the circuit is after MX-01 type IC sheet 11 is handled, control loudspeaker gives the alarm, thereby a kind of information of locked object body situation is provided to the user.When lock is in unlock state, dial tongue 2b and break away from trigger switch 1, dial groove and battery case lid sidewall notches that tongue 2a and 2b, 2c also break away from dead bolt 4 respectively, at this moment object is subjected to displacement or vibrates and can not make circuit turn-on, thereby also can not report to the police.

The utility model will be further described below by accompanying drawing, so that understand the utility model better.

Fig. 1 represents the structure chart of the utility model lock.

Fig. 2 is the sectional view of Fig. 1 along A-A.

Fig. 2 is the sectional view of Fig. 1 along B-B.

Fig. 4 is the utility model circuit diagram.

Fig. 5 is parts 2 detail drawings of Fig. 1.

Fig. 6 is the view of the parts 3 of Fig. 1.

Fig. 1 is the structure chart of lock, the utility model lock is made up of lock body 7 and battery case 8, lock body 7 is made up of lock core 6, plectrum 2, dead bolt 4 and trigger switch 1, its lock core is the same with general lock structurally with dead bolt, be not described in detail at this, the plectrum of general lock only has one and dials tongue, and the plectrum 2 of this lock has three to dial tongue, structural representation Fig. 5 of plectrum 2, can see by Fig. 5, dial tongue 2a, 2c and 2b is vertical configuration for three, can see by Fig. 1, when being locked in locking, dead bolt 2b is in the groove of battery case lid 3 sides.

Fig. 2 is the sectional view of Fig. 1 along A-A.Dial tongue for one in the plectrum 2 and be in the groove of lid 3 sidewalls, another group tongue is in dead bolt 4 grooves, and Fig. 3 is the sectional view of Fig. 1 along B-B.It can illustrate the connected mode of trigger switch 1 and lock body 7.Among Fig. 2 and Fig. 35 is the pellet shot from a slingshot in the general lock.Fig. 6 is the sectional view of the battery cover 3 of Fig. 1 along C-C.

Battery case lid 3 is coupled together by extension spring 13, because the effect of extension spring, battery box 8 and battery case lid 3 can closely cooperate, can also relatively move, so that install or take out the battery 14 in the battery case, as battery case the same, battery is to be fixed in the battery case by spring 9, loudspeaker 10 is housed on battery case, MX-01 type IC sheet 11, vibroswitch 12, because the place difference that lock uses, the shape and the size of lock can be very inequality, so these parts can be according to the space flexible arrangement in the battery box 8, promptly shape and the size according to box body places any position in the box, can be as shown in Figure 1, vibroswitch 12 is placed in the battery case, and with loudspeaker 10, MX-01 type IC sheet 11 is placed on battery box 8 outer ends, then together with loudspeaker 10, MX-01 type IC sheet 11 places battery case a firm shell (Fig. 1 does not draw) together, also can otherwise dispose, for example with loudspeaker 10, MX-01 type IC sheet 11 all is contained in the battery case, assembling all should help propagating outward between sound that loudspeaker sends in any case, and loudspeaker 10, MX-01 type IC sheet 11, vibroswitch 12, trigger switch 1, battery 14 needs to couple together according to Fig. 4 circuit diagram.The K of Fig. 4 ₁And K ₂Be respectively vibroswitch 12 and trigger switch 1.The 11 no any specific (special) requirements of MX-01 type IC sheet, its connection in circuit can be carried out according to its product description according to the integrated circuit chip specification.The employed loudspeaker 10 of the utility model, MX-01 type IC sheet 11, vibroswitch 12, trigger switch 1 all are the products that existing market is locked and sold.

When lock is in unlock state, dial tongue 2b and be in disengaging trigger switch 1, dial groove and battery case lid 3 sidewall notches that tongue 2a and 2c also break away from dead bolt 4 respectively, at this moment object is subjected to displacement or vibrates and can not make circuit turn-on, thereby also can not report to the police.

The utility model lock construction is simple, sensitivity, in case object is moved a little by other people or other vibrations take place, this lock will give the alarm immediately, and its article will effectively be protected, and this lock is with low cost, can be widely used in the various aspects of people's life.
