Description

A kind of antitheft, security stamp

The utility model belongs to the improvement of office with seal structure, relates to touching counting and touching field of sensing technologies.

The phenomenon of usurping and forging the office seal now is more and more, and especially national economy key departments as customs, the tax, bank etc., have this phenomenon then can cause very big loss to country.Chinese patent 96235863.0 applications have designed a kind of anti-counterfeit anti-theft seal structure, be that device has mechanical counter in seal, every lid once prints counting once, its counting shows at the seal overcoat, count in addition when affixing one's seal and record the affix one's seal time and the origin of an incident, it is provided with the stamp-pad ink storage chamber in Stamp handle, and is added with fluorescent material in stamp-pad ink, with stamp-pad ink centralized management, thereby reach the purpose of Theft-proof and anti-counter.This structure in use has the following disadvantages: 1. be directly proportional time of contact with fluorescent material and light, air owing to fluorescence decay, generally fluorescence disappears behind 1-2, so this stamp-pad ink uses the back longer apart from the crime time, debate the true and false with regard to difficulty, moreover the imitated of fluorescence stamp-pad ink is easily; 2. this seal is the same with common seal, the Zhang Yin that it covered is the same, there is not any mark, can't contrast the independent Zhang Yinyu record of affixing one's seal, when using this seal, not make counter driving lever return like this as long as pin the seal overcoat, impress continuously repeatedly, and only reflecting once that on counter the chapter seal that it covered out can't identify time and order, this leaves opportunity just for usurping of seal; 3. owing to the aging flexible reduction of chapter face causes repeat count, and because of stamp-pad ink too much or the unintelligible of the very few Zhang Yin of causing affixed one's seal again, the record that a certain numbering " calcellation " just occurred, because the Zhang Yinben body is unmarked, too much calcellation record causes the Zhang Yin that really usurps also to have no way of having looked into; 4. because any mark of Zhang Yinwu, and the impressing and use each minute two places of document, so the judgement of the chapter seal true and false is had no way of doing it, this leaves chance with regard to the forgery to seal.

The purpose of this utility model is at above-mentioned defective, designs necessarily antitheft, security stamp, to solve described existing problems.

The designed structure antitheft, security stamp of the utility model is, lower surface device at the seal body that is made of Stamp handle and seal base has seal chapter face, hypomere at the seal body is with sliding outer cover, between overcoat and body, be provided with return spring, be provided with mechanical counter in chamber body, characteristics of the present utility model are: described mechanical counter is the counting marking machine, be installed on the chapter face at the bottom of the seal body cavity, it is printed number and is exposed to outside the chapter face, and can imprint chapter and stamp; Its counting driving lever stretches out the seal chamber body, and in that the seal body is descending when impressing, driving lever can be stirred counting by the projection that the sliding outer cover inwall is provided with.

Characteristics of the present utility model also are, in the chapter face, be embedded with touch sensor, sensor line causes the seal chamber body and is connected with the counter circuit plate with the power supply of setting, and fixture has liquid crystal digital display board and computer interface on sliding outer cover, and its circuit is connected with the counter circuit plate.Wherein touch sensor can adopt permanent magnet and magnetosensitive filaments of glass to be spaced formation.

By such scheme as can be seen, because the designed seal of the utility model can be shown in numbering on the seal, equal to have made mark to seal, all seals that cover out, cancel, forge and usurp all can be in the middle verification of keep a record like this, from the time, in proper order, the origin of an incident differentiates; The utility model also can have electronic counter by device in addition, and its counting numbering is corresponding with the mechanical count numbering, by the record storage and the networking of computer, can carry out remote record queries.Thereby the loss that can avoid usurping, falsification of seal brought realizes the purpose of this utility model.The seal that it is applicable to national economy key departments has advantage simple in structure, that making is easy, easy to use, the anti-counterfeit anti-theft performance is strong.

Accompanying drawing 1 is the structural representation of designed antitheft, the security stamp of the utility model, and accompanying drawing 2 is designed seal chapter face front schematic view.1 for having the seal body of handle and base among the figure, 2 is return spring, and 3 is sliding outer cover, and 4 is the electronic counting wiring board, 5 is the liquid crystal digital display board, 6 is mechanical counter counting driving lever, and 7 is projection, and 8 is the touch sensor of burying underground in the seal chapter face, 9 is computer interface, 10 is power-supply battery, and 11 is mechanical counter, and 12 is seal chapter face.

Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.

Referring to accompanying drawing, the designed structure antitheft, security stamp of the utility model is, lower surface device at the seal body 1 that is made of Stamp handle and seal base has seal chapter face 12, is with sliding outer cover 3 at the hypomere of body, is provided with return spring 2 between overcoat 3 and body 1; Device has counting marking machine 11 on the chapter face 12 of body 1 intracavity bottom, makes it print number and is exposed to chapter face 12, and can impress and stamp at chapter, because the restriction of volume, its counting marking can be selected the coding of non-ten carries, even can be bar code etc., has more antifalsification like this; Counter driving lever 6 stretches out body 1 inner chamber, can be stirred counting by the projection 7 of sliding outer cover 3 inwall settings when impressing in that the seal body is descending.The touch sensor of burying underground in chapter face 12 8 adopts permanent magnet and the magnetosensitive filaments of glass of 3 * 0.3mm to be spaced formation, and the two ends line is connected with counter circuit plate 4 with the power supply 10 that body 1 inner chamber is provided with; Being spaced in the chapter face of sensor filament can be in-line, triangle, circular arc etc., even spaced filament can be preset in wherein when the making of chapter face, only needs connection line when the system chapter; Fixture has liquid crystal digital display board 5 (being similar to the LCD panel of electronic watch) and computer interface 9 on sliding outer cover 3, and both circuits are connected with the counter circuit plate.During use, be subjected to the effect of little power to make spaced filament occur being interrupted at the chapter face, cause the fixedly variation of magnetic resistance, thereby form a switching signal, entry-line plate counting, and on display board 5, show, can also make numbering enter the logging program that is provided with in the computer by computer interface and enter storage.
