The method of the safety of existing increase theftproof lock and anti-theft key mainly contains: increase the quantity of the tooth of anti-theft key or change the kind of key bit, such as cross key, when same length and tooth density, its number of teeth is four times of normal key, or use flat key, replaces tooth to increase the difficulty be imitated with the pit on flat key; Use the novel lock such as electronic lock, coded lock.Along with the progress of science and technology, novel driven opening lock tool still can be opened and add tooth or use pit to replace the lock of tooth, and although the novel anti-burglar lock such as electronic lock, coded lock theftproof performance is better, but its cost is higher, and the structure of the structure of its key and lock and existing key and lock difference to some extent, its versatility is bad, and reliability is unstable, may cause obstacle in use habit.
Utility model content:
For solving prior art Problems existing, the utility model proposes that a kind of cost is low, structure is reliable, the easy to use and theftproof lock of good anti-theft effect.
For achieving the above object, the utility model by the following technical solutions: a kind of theftproof lock, comprises electronic lock and electron key, and described electronic lock comprises lock core, is provided with some pellets in the lockhole of lock core; Described electron key comprises key bar and the shank of the key, key bar is provided with the some key bits corresponding with described pellet, be characterized in: key bar is provided with piezoelectric ceramics battery and infrared emission tube, be provided with the driving chip of infrared emission tube in the shank of the key, driving chip connects piezoelectric ceramics battery and infrared emission tube; Be provided with the infrared receiver tube corresponding with described infrared emission tube in the lockhole of lock core, infrared receiver tube is connected to the controller of electronic lock; Lock core lateral surface is provided with groove, in electronic lock, be provided with electric pushrod, and the outer end of electric pushrod is fixed in electronic lock, and its inner is provided with the plate corresponding with described groove, and controller is connected with electric pushrod.
Described electric pushrod comprises shell, and in shell, bottom is fixedly installed electromagnet, and top movable is provided with armature, spring is provided with between electromagnet and armature, armature is connected with the plate outside shell by drive link, and electromagnet is connected with controller, and shell is fixedly installed in electronic lock.
Described driving chip is pic10f20x single-chip microcomputer.
Described infrared emission tube is recessed head transmitting tube.
The beneficial effects of the utility model: the profile of electron key of the present utility model is identical with traditional keys, use more convenient, cost is low, the strong and good anti-theft effect of reliability.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of electron key of the present utility model;
Fig. 2 is the structural representation that electron key of the present utility model coordinates with the lock core of electronic lock;
Fig. 3 is the structural representation of the electric pushrod of Fig. 2;
Wherein: 1-lock core, 2-pellet, 3-key bar, 4-the shank of the key, 5-key bit, 6-piezoelectric ceramics battery, 7-infrared emission tube, 8-driving chip, 9-infrared receiver tube, 10-groove, 11-plate, 12-electric pushrod, 13-shell, 14-electromagnet, 15-armature, 16-drive link, 17-spring.
Detailed description of the invention:
Below in conjunction with drawings and Examples, the utility model is described in further details:
As shown in Fig. 1 ~ Fig. 2, a kind of theftproof lock, comprises electronic lock and electron key, and described electronic lock comprises lock core 1, is provided with some pellets 2 in the lockhole of lock core 1; Described electron key comprises key bar 3, the shank of the key 4, key bar 3 is provided with the some key bits 5 corresponding with described pellet 2, key bar 3 is provided with piezoelectric ceramics battery 6, key bar 3 is provided with the infrared emission tube 7 of recessed head, the driving chip 8 of infrared emission tube 7 is provided with in the shank of the key 4, driving chip adopts pic10f20x single-chip microcomputer, its power consumption is less, adopt sot23 encapsulation, volume is about 3mm*3mm*1.2mm, can be built in the shank of the key 4, driving chip 8 connects piezoelectric ceramics battery 6 and infrared emission tube 7; The infrared receiver tube 9 corresponding with described infrared emission tube 7 is provided with in described lockhole, infrared receiver tube 9 is connected to the controller of electronic lock, controller adopts 8051 single-chip microcomputers, its performance is more reliable, and can be encrypted in the signal of infrared emission tube 7 and infrared receiver tube 9 Direct Communication, lock core 1 lateral surface is provided with groove 10, is provided with electric pushrod 12 in electronic lock, and electric pushrod 12 is connected to controller.Electric pushrod 12 comprises shell 13, in shell 13, bottom is fixedly installed electromagnet 14, top movable is provided with armature 15, spring 17 is provided with between electromagnet 14 and armature 15, armature 15 is connected with the plate 11 outside shell 13 by drive link 16, electromagnet 14 is connected with controller, shell 13 is fixed in electronic lock, groove 10 is corresponding with plate 11, when electromagnet 14 is not charged, armature 15 and drive link 16, plate 11 is in the state away from electromagnet 14, thus locked lock core 1, stop it to rotate, when electromagnet 14 is charged, armature 15 adhesive is to electromagnet 14, plate 11 is extracted from groove 10, lock core 1 can rotate.
Be below the process of once unblanking of the present embodiment:
Supporting electron key is inserted the keyhole of electronic lock, in the process of insertion, piezoelectric ceramics battery 6 is under pressure, and produces energy of position, thus starts driving chip 8, and then makes infrared emission tube 7 send infrared light.After infrared receiver tube 9 receives infrared light, signal can be sent to controller, controller is energized to electromagnet 14, inhales lower armature 15 and is pulled out from groove 10 by plate 11 by drive link 16.Because the top edge of the pellet 2 of correspondence all have been shifted onto the edge of lock core inner core by the key bit 5 of differing heights, now can rotate electron key and open electronic lock.
Existing bitting process mainly joins identical key bit 5, the present embodiment middle infrared (Mid-IR) transmitting tube 7 is recessed head transmitting tube, can be hidden in the installing hole on electron key, because the profile of the utility model electron key is identical with normal key, be difficult to notice that the key taken not is common key by during the bitting of people's malice, only can be fitted on identical key bit 5, and be difficult to make identical driving chip 8, piezoelectric ceramics battery 6 and infrared emission tube 7, and unlocking tool cannot judge the position of infrared receiver tube 9 accurately, also the signal of infrared emission tube 7 cannot be forged, thus namely allow to use traditional method all to shift pellet 2 onto correct position, plate 11 and groove 10 also can stop the rotation of lock core 1, thus electronic lock cannot be opened.Because electron key of the present utility model is identical with the profile of normal key, using method is also identical, does not need extra key etc., under the prerequisite not changing user's use habit, improve theftproof performance.
