Abstract

The utility model relates to an electric shock type theft-proof safe whose interior is provided with a high-voltage electricity generating system which does not work at ordinary time. When a safe door is opened and a drawer which is in the safe is pulled, electric shock high voltage is immediately generated to electrify metallic bodies of the safe unless openers press cryptographic keys or insert an external power before the drawer is pulled and use emergency keys. Since the utility model is also provided with a dislocation key, the wrong opening rate is low, and the confidentiality is excellent. When high voltage is generated, users can transmit specific radio waves to turn off a high voltage generation circuit by a remote-control transmitter carried by the users. The utility model has the advantages of no power consumption at ordinary time and no false action of a self-safety safe whose ciphers are set outside.

Description

Electric shock type theft-proof safe

In International Classification of Patents, the utility model belongs to the E05G group, and promptly this group of insurance of valuables case or strong-room is also classified with electric department and is related.

Find by retrieval, the innovation and creation of relevant insurance case, disclosed few in Gazette of Patent for Invention; And in the utility model patent communique, announce quite a lot of.Now just the application for a patent for invention of " strongbox of tool warning system " (application number 90103069.4, notification number CN1053467A) makes a presentation.These innovation and creation are made with engineering plastics, and its appearance is provided with metalolic network, and the warning circuit in the case links to each other with described metalolic network.During password button outside being located at case input pseudo-code, or when opening afterwards with pseudo-spoon, or when shaking this casing, after time-delay in 10 seconds to 30 seconds, high-tension electricity on the metalolic network band, audible alarm, transmitted radio signal simultaneously are by near Security Services wireless receiving system is received.Function that should this strongbox is comparatively complete, and self-protecting device has been arranged.But, obvious defects is also arranged, for example, when non-theft purpose is touched, also can produce action because the password button is located at outside the case.Main disadvantage is that battery ceaselessly powers and cause that power consumption is too big, simultaneously owing to components and parts cause cost high too much.About this point, can from admitting, the frankness its prospectus be confirmed.

The purpose of this utility model is to provide a kind of strongbox simple in structure, when chamber door is opened, in the case drawer when pulled, the power supply in the case is switched on, thereby produces high pressure, reaches from anti-.

Above-mentioned purpose is accomplished by following scheme:

It is by chamber door, and casing and being installed on is formed comprising at least by the system for high pressure production of door electricity circuit for producing high voltage in the case.Door switch is series among the current supply circuit of gate circuit.Several buttons comprise and press the password button that can make gate circuit connect power supply successively, press the dislocation button that after one of them the password button was lost efficacy, and also are arranged in the case.Several limit switches are installed in latent my place in the case, and these limit switches comprise the contact switch of relay, and the current supply circuit that all is series at circuit for producing high voltage is in this, and said limit switch is is all opened or closed by the determining positions of drawer in the case.

This electric shock type thief-resistant safe has the following advantages: at first just connect when chamber door is opened owing to power supply, so power consumption is few; Secondly all components and parts all place in the case, and its high pressure self-shield effect only just produces when opening chamber door and spurring drawer, have prevented that the sort of case that is loaded on from not being the misoperation of theft purpose when touching outward; Be that circuit is simple once more, the components and parts number is equivalent to the circuit unit number in the background technology.

Fig. 1 is the structural representation of an embodiment in the utility model, is appointed as Figure of abstract.

Fig. 2 is an embodiment schematic diagram of limit switch and drawer positions relation in the utility model.

Fig. 3 is for being connected to indicator lamp, wireless remote control reception and danger button embodiment of circuit electrical schematic diagram in the utility model.

Below in conjunction with accompanying drawing, embodiment is described.

S1 to S12 is several buttons ［ 8 ］ among Fig. 1 among Fig. 3, and wherein S5 to S8 is the password button, presses successively to make integrated package and BG1 conducting in the gate circuit; S9 to S12 is the dislocation button, presses one of them and can make the energy storage abrupt release of corresponding capacitance and cause the action of pressing of password button to lose efficacy.S1 to S4 is a danger button, but is not essential feature.These 8 or 12 button profiles can be consistent, and are arranged in together, make the time lengthening of souning out password.

BG2 and B5 etc. form high-pressure generating circuit.Its high-pressure side links to each other with the strongbox metallic object.In the current supply circuit of this circuit, at least be in series with the gate circuit relay contact switch, with drawer ［ 6 ］, the relevant limit switch in ［ 7 ］ position, wherein S14 is the limit switch ［ 13 ］ among Fig. 2, path at ordinary times, drawer opens circuit when extracting out fully, S15, S16 for the limit switch ［ 12 ］ among Fig. 2, open circuit path when drawer is pulled away from ordinary times.

When chamber door ［ 2 ］ along door hinge ［ 1 ］ when drawing back, door switch ［ 10 ］ is that S13 connects, gate circuit has had the power supply supply.Measure BG1 conducting, the line bag energising of relay 1J when pressing password button S5 to S8 successively, its corresponding contact switch 1J inhales downwards, the high-pressure generating circuit that BG2, D5 form does not have electricity (originally yet not having electricity, because of S15, S16 open circuit) yet, so spur drawer ［ 6 ］, ［ 7 ］ with regard to safety.When drawer was all pulled out, S14 disconnected, and can at this moment change power supply or repairing.

When pushing drawer once again, should press password button S5 to S8 earlier.

When once pressing dislocation key (among the S9 to S12 any) in the button ［ 8 ］, corresponding capacitance energy storage abrupt release, BG1 can not conducting.If pulling ［ 6 ］, ［ 7 ］ again, then connection among S15 or the S16, or S15, S16 connect simultaneously, high pressure produces immediately, does not touch the button ［ 8 ］ and also produces high pressure when direct pull drawer ［ 6 ］, ［ 7 ］.

On the basis of the above, can also increase one or several function.For example danger button S1 to S4 pins when not putting simultaneously, the energising of relay 2J line bag, and its contact switch 2J closes downwards, and high pressure opens circuit.Example 2 is an indicating circuit, and indicator lamp ［ 9 ］ can be green, yellow, red, shows different states respectively.Example 3 is a radio receiver circuit, is made up of BG3, BG4, and its corresponding remote control transmitter band is on one's body owner.When the burglar pulls the drawer out the high pressure generation simultaneously, the receiving circuit power connection, this moment is when pressing the power switch S17 of remote control transmitter, the signal of being launched is received by receiving circuit, BG3 conducting, the energising of relay 3J line bag, its contact switch 3J disconnects, no high pressure produces, and this remote control transmitter is connected to the power supply output plug, can insert socket on the strongbox ［ 11 ］ and be the emergency operation power supply.

Except that transmitter, above-mentioned all components and parts are all in safe body ［ 8 ］, when drawer ［ 6 ］, ［ 7 ］ are shifted onto in the case, S15, S16 open circuit, and when chamber door ［ 2 ］ closes, door switch ［ 10 ］ is that S13 opens circuit, power supply all cuts off, and as for mechanical lock ［ 5 ］, handle ［ 4 ］ is no longer introduced.

When high-tension circuit designs, considered that its energy shortage is to cause the burglar dead or maimed.The wiring of some buttons ［ 8 ］ can be used connector, so that layout password voluntarily.
