Description

Portable safe

The utility model belongs to anti-theft and anti-robbing safe box device field, can be widely used in bank, shop and house, revolve to swim and deposit or carry valuables, and thief-proof anti-snatch self-defence effect is arranged.

The anti-theft and anti-robbing strongbox of report has induction control type and switch controlled two big classes at present; The Chinese patent of induction control type has CN2052633U, and CN2079897U, CN2087903U realize by the touch of hand or wireless remotely-controlled sensing, make to send in the casing and report to the police or other action of defending oneself.The weak point of touch induction is easy wrong report, as triggering on crowded motor bus, easily injures the case friendly neighbour that advocates peace; Wireless remotely-controlled employing electromagenetic wave radiation control, no matter how secret its control coding is, because CF signal energy low (being generally several milliwatts) is subjected to the spark plug discharge in space easily, the fault that strong clutter radiation interference such as electric welding electromagnetic radiation produces false triggering or can not trigger.The wireless remotely-controlled restriction that also is subjected to distance within the specific limits can not in time be reported to the police and defend oneself reliably.The Chinese patent of switch controlled has CN2109110U, CN2115559U, and this system is both economical practicality, but owing to the switching mechanism complex structure is difficult to manufacturing or influences outward appearance because of gauge tap exposes.Discerned the control main points and lose antitheft effect by thief or other people easily.Mechanical switch is subjected to high vibration or because of the direct reliability that influence the switch combination of crowded occasion meeting, also occurs false triggering easily.

Defensive avionics system generally adopts audible alarm and electric shock self-defence dual mode.Audible alarm is similar, will not give unnecessary details; Though the electric shock defensive avionics system has certain effect.But because all multifactor influences such as design and manufacturing, the ruffian that will really accomplish to shock by electricity accurately and reliably is not so easy just, what at first show is that electric shock voltage is low, generally about one kilovolt, the ruffian can isolate electric shock voltage by insulants such as gloves, can not reach the purpose that electric shock is defended oneself; Though next is the electric shock voltage that designs volts up to ten thousand are arranged, but because high-field electrode is provided with unreasonable on casing, in tourism, be caught in the rain or case in be placed with things such as wet towel and directly increase the weight of the electrion load and make the very fast high pressure of voltage on the high-field electrode drop to 1～2 kilovolt from volts up to ten thousand, even tens volts, do not reach the effect that electric shock is defended oneself yet.The third is that the charged area of design is little, and it is charged or the tank surface part is charged to be generally handle, and because of can not effectively touching the electric shock position, the effect that shocks by electricity did not almost have when the ruffian committed a crime; The 4th kind is that the output circuit of high-tension electricity is unreasonable, and load capacity is poor especially, can not large tracts of land realize charged self-defence effect on casing.

Secondly equal complex structure of this two big class control system, the processing and manufacturing difficulty is big, the cost height, the shortcoming that power consumption is big, particularly the replacing battery is frequent in tourism, often more renews the battery error of defending oneself because of forgetting.

The purpose of this utility model is to provide a kind of non-attack portable safe at the deficiencies in the prior art, it has the electric bridge sensing of electronic circuit, the secondary booster circuit of reverse-blocking tetrode thyristor control and thyristor controlled capacitor charge and discharge, can realize reporting to the police and to produce 20,000 volts of above electric shock voltages all charged for tank surface and handles, anti-theft and anti-robbing safety height, volume is little, in light weight, make simple, cost is low, easy to operate, accurately and reliably, not affected by environment, can be widely used in bank, the shop, valuables are deposited or are carried in house and tourism, as the gold, silver and jewelry jewellery, security document bankbook and check banknote etc. has anti-theft and anti-robbing to report to the police and electric shock self-defence effect.The transient voltage height, electric current is little, can only hit unconsciously, can not hit extremely, makes the thief ruffian forbidding, touches and runs away.
