Abstract
The utility model relates to fingerprint extracting adhesive tape which comprises a transparent base body, pull pieces, a dotted-line notch and colored pressure-sensitive adhesives. The dotted-line notch is longitudinally arranged in the middle of the transparent base body, the upper end and the lower end of the transparent base body are respectively provided with two semicircular or square or trapezoid pull pieces, the two pull pieces at the same end are symmetrically distributed on the left side and the right side of the dotted-line notch, the transparent base body and the pull pieces are of an integrated structure, and the colored pressure-sensitive adhesives are arranged on the lower surface of the transparent base body. The fingerprint extracting adhesive tape has the advantages that the dotted-line notch is longitudinally arranged in the middle of the transparent base body, the thumb of one hand presses a part, on one side of the dotted-line notch, of the adhesive tape, the other hand slightly exerts pressure, and therefore the adhesive tape can be easily torn down; the fingerprint extracting adhesive tape is pasted on a fingerprint, then the fingerprint extracting adhesive tape is torn down, a colored fingerprint mark is left on the colored pressure-sensitive adhesives, extracting efficiency is improved, the fingerprint can not be damaged, gold powder or silver powder does not need to be smeared on fingerprints of a dead body, contact of heavy metals and the human body is avoided, and the fingerprint extracting adhesive tape can be widely used for fingerprint extracting work.
Description
Technical field
This utility model relates to a kind of fingerprint extraction device, relates in particular to a kind of fingerprint extraction adhesive tape.
Background technology
At present, the method that tradition is extracted corpse fingerprint is: 1, fingerprint stamp method, corpse is pointed with suitably uniform pressure by being pressed on ink pad, then the finger that has red ink paste used for seals is transferred on blank sheet of paper, the drawback of this method is due to after death body hardening and stiff formation cadaveric rigidity gradually of people, ankylosis is difficult to stamp, and effect is undesirable, 2, first adopt significant powder brush, with adhesive tape, paste the powder method of extracting again, be to be stained with after a little bronze or argentum powder with hairbrush, on corpse fingerprint, smear back and forth, from transparent fingerprint adhesive tape, tearing off an adhesive tape again sticks on the fingerprint with powder, make powder fingerprint adhesion on adhesive tape, then take adhesive tape off, by the adhesive tape with fingerprint be bonded at one with the larger substrate of impression of the hand contrast on, take the fingerprint in this way more complicated, when tearing off, easily tears by conventional fingerprint adhesive tape, and powder is smeared when overweight, fingerprint extraction is unintelligible, need brush dust again, brush dust easily produces dust raising phenomenon again, be unfavorable for that staff's is healthy.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of simple in structure, fingerprint extraction adhesive tape easy and simple to handle, be used in conjunction with bottom lining plate, greatly improve the success rate of fingerprint extraction, and need on corpse fingerprint, not smear back and forth bronze or argentum powder, avoid contacting of heavy metal and people, safeguard work personnel's is healthy.
This utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is:
A kind of fingerprint extraction adhesive tape, comprise transparent base 1, peel 2, dotted cut 3 and coloured pressure sensitive adhesive 4, transparent base 1 middle part longitudinally arranges dotted cut 3, and transparent base all arranges the square or trapezoidal peel 2 of two semicircles in two ends Shang Xia 1, with two peels 2 of one end, is symmetrically distributed in dotted cut 3 left and right sides, transparent base 1 is integral type structure with peel 2, and transparent base 1 lower surface arranges coloured pressure sensitive adhesive 4.
Described transparent base 1 is plastic sheeting.
Described plastic sheeting is BOPP transparent membrane or polyvinyl chloride transparent thin film.
The thickness of described transparent base 1 is 0.03-0.05mm.
The thickness of described coloured pressure sensitive adhesive 4 is 0.01-0.03mm.
Described transparent base 1 arranges circular arc 5 with the junction of peel 2, and on-right angle design, adopts arc structure transition, the junction of transparent base 1 and peel 2 easy fracture not while tearing off.
The radius of described circular arc 5 is 3-5mm.
The radius of described circular arc 5 is 4mm.
Operation principle of the present utility model: dotted cut is to utilize broken line knife compacting, leaves a dotted line being comprised of a plurality of otch interval on transparent base, cuts apart conveniently; Described coloured pressure sensitive adhesive, is that pigment and water are mixed into pasty state and grind to form mill base, and the auxiliary agents such as mill base and wetting agent, diffusant, dispersant add in transparent pressure sensitive glue formulated; Described peel and the cutting of transparent base one form, and are material of the same race, hold peel and upwards carry, and transparent base easily can be mentioned.When this fingerprint extraction adhesive tape is used, by thumb press, live on the other hand a side of dotted cut on adhesive tape, another hands can be torn adhesive tape easily to the peel application of force slightly, can cut according to concrete conditions such as the quantity of fingerprint on site, areas the fingerprint extraction adhesive tape of right quantity, while taking the fingerprint, hold on the other hand fingerprint extraction adhesive tape, from a side roll-in of fingerprint on fingerprint, then fingerprint extraction adhesive tape is taken off, can on coloured pressure sensitive adhesive, remember by fingerprints, the fingerprint extraction adhesive tape sticking with fingerprint mark, on liner plate, liner plate is put into file sealing bag and is preserved.
The beneficial effects of the utility model are: 1, transparent base middle part longitudinally arranges dotted cut, cut apart conveniently, live on the other hand a side of dotted cut on adhesive tape by thumb press, and another hands is slightly exerted pressure and can easily adhesive tape be torn.2, fingerprint extraction adhesive tape sticking is on fingerprint, then fingerprint extraction adhesive tape is taken off, on coloured pressure sensitive adhesive, can leave coloured fingerprint mark, improve extraction efficiency, survivable fingerprint, and need on corpse fingerprint, not smear back and forth bronze or argentum powder, avoid contacting of heavy metal and people, can be widely used in fingerprint extraction work.3, adopt BOPP transparent membrane, there is high tensile, impact strength, rigidity, obdurability and the good transparency.4, the junction of transparent base and peel arranges circular arc, on-right angle design, the junction of transparent base and peel easy fracture not while tearing off.5, described peel and the cutting of transparent base one form, and are material of the same race, hold peel and upwards carry, and transparent base easily can be mentioned.
