Description

Strongbox

Technical field

The utility model relates to the strongbox technical field, specifically a kind of strongbox with warning function.

Background technology

Along with the continuous development of society, strongbox has had certain popularizing.Strongbox not only is widely used in unit, and strongbox begins to come into gradually family.Yet strongbox is as the facility of depositing valuables, and it becomes thief's target naturally easily.So the antitheft problem of strongbox can not be ignored.

The anti-theft device of current extended insurance case has a lot, and also all form is different for the technology of use and material, is used for the antitheft of strongbox in succession as special electronic lock, coded lock etc.But these anti-theft devices mainly are to prevent that strongbox is opened, and some less strongboxs are when being not easy to be opened, and the robber moves strongbox is whole probably.This can cause user's loss equally.

Because the defective that above-mentioned existing strongbox exists, the design people is actively studied innovation, in the hope of founding a kind of strongbox of new structure, makes it have more practicality.

The utility model content

In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of strongbox, and the utility model is simple structure not only, and is cheap, but also be not easy destroyed, thereby be suitable for practicality more, and have the value on the industry.

In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:

Strongbox, comprise casing and be located at the interior warning device of casing, described warning device comprises laser scanner, multivibrator, alarm and trigger board, and wherein laser scanner is connected with multivibrator, and multivibrator is connected with alarm, trigger board comprises end face and bottom surface, the both sides of bottom surface have bar code, form trigger region, are the clear area between the bar code, trigger board hangs on the top of casing, and the clear area of trigger board is corresponding with laser scanner.

Further, described alarm is electric bell, phonetic alarm or GSM alarm module.

Further, described multivibrator is made of 555 timers.

Further, described trigger board hangs on the casing top by swing arm, and the length of swing arm is 4.5～5: 1 with the length of white space ratio.

Further, the length of swing arm is 4.75: 1 with the length ratio of white space.

Compared with prior art, the beneficial effects of the utility model are:

The utility model is simple structure not only, and cheap.Form warning circuit by laser scanner, multivibrator and alarm, during use, laser scanner is aimed at the trigger board middle part, when the robber moves strongbox, trigger board is swung as pendulum under gravity and action of inertia, at this moment, laser scanner scans the bar code of trigger board both sides, and the multivibrator conducting triggers alarm equipment alarm.As seen, the utility model also have safe, sensitivity good, practical characteristics.And the warning device good concealment of strongbox of the present utility model, also be not easy destroyed.Strongbox of the present utility model can prevent effectively that strongbox from being stolen the generation of situation by integral body.

Fig. 2 is the electrical schematic diagram of preferred embodiment of the warning device of strongbox of the present utility model;

Fig. 3 is the structural representation of trigger board of the warning device of strongbox of the present utility model;

Fig. 4 is the structured flowchart of the warning device of strongbox of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to qualification of the present utility model.

As shown in Figures 1 to 4, Fig. 1 is the structural representation of strongbox of the present utility model, and Fig. 4 is the structured flowchart of the warning device of strongbox of the present utility model.Strongbox comprises casing 9 and is located at the interior warning device of casing that described warning device comprises laser scanner 2, multivibrator 3, alarm 4 and trigger board 1, and wherein laser scanner 2 is connected with multivibrator 3, and multivibrator 3 is connected with alarm 4.Fig. 3 is the structural representation of trigger board of the warning device of strongbox of the present utility model.Trigger board 1 comprise end face 7 and with end face 7 opposed bottom surface, trigger board 1 hangs on the top of casing 9 by swing arm 8, swing arm 8 links to each other with the center of the end face 7 of trigger board 1, the both sides of the bottom surface of trigger board 1 have bar code 5, form trigger region, be clear area 6 between the bar code, clear area 6 is corresponding with laser scanner.Fig. 2 is the electrical schematic diagram of preferred embodiment of the warning device of strongbox of the present utility model.Multivibrator 3 is made of 555 timers, and the input of multivibrator 3 links to each other with laser scanner 2, and the output of multivibrator 3 links to each other with the base stage of a triode, and the colelctor electrode of triode connects alarm 4.Alarm in the present embodiment is electric bell or buzzer.Certainly, alarm also can adopt other as GSM alarm module, GPRS alarm module or audio alert module etc.

The overall cost of strongbox of the present utility model is compared very nearly the same with the general insurance case, warning device accounts for the extremely low ratio of total cost.But good anti-theft effect.Comparing with the general insurance case, is all to have certain advantage on price or the performance.

The trigger board 1 of the warning device of strongbox of the present utility model is suspended from the laser scanner top, trigger board 1 can freely swing in the plane perpendicular to laser scanner as pendulum, the both sides of the bottom surface of trigger board 1 are provided with bar code 5, form trigger region, the middle part of the bottom surface of trigger board 1 (between the bar code) is not for being provided with the clear area 6 of bar code, and laser scanner 2 is aimed at the center of the clear area 6 of trigger board.Laser scanner 2 is by 5V power supply power supply, and is in running order always, under normal circumstances, laser scanner 2 faces the clear area 6 in the middle of the iron plate, and this moment, circuit was not conducting.When the people wants to steal strongbox, as long as he one moves strongbox, trigger board will be at gravity and action of inertia lower swing, thereby laser scanner 2 is departed from the clear area of trigger board 6, this moment, laser scanner 2 will shine the bar code 5 on next door, reported to the police so circuit turn-on triggers alarm 4.When alarm 4 adopts electric bell, buzzer, can send the tinkle of bells or buzzer.When alarm 4 adopted GSM alarm modules or GPRS alarm module, the phone that GSM alarm module or GPRS alarm module can send note or dial setting was reported to the police.When alarm 4 adopted the audio alert module, the audio alert module can be sent the voice of setting and report to the police.Warning sensitivity of the present utility model can break away from the pendulum angle of laser scanner by the white space of adjusting trigger board to be realized, simple.Record through test, it is preferable that the warning pendulum angle is controlled at the 6 degree left and right sides, swings in the scope of 0～6 degree and can not trigger warning, and this angular range not only has higher sensitivity, and has overcome the wrong report problem of bringing because of the ground out-of-flatness.And the length of the length of warning pendulum angle and swing arm and white space is than relevant, and when the warning pendulum angle was the 6 degree left and right sides, the length of swing arm was 4.5～5: 1 with the length of white space ratio, and the length of swing arm is preferably 4.75: 1 with the length of white space ratio.

Above embodiment is an exemplary embodiment of the present utility model only, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the utility model in essence of the present utility model and protection domain, this modification or be equal to replacement and also should be considered as dropping in the protection domain of the present utility model.
