Description
Technical field
The invention belongs to a kind of thief-proof false proof lead sealing method and device of being applied to; relate to true and false false proof of a kind of this method and apparatus lead sealing; and the coupling part identification of being changed; be used to prevent the table of protected object; case; the conversion that is opened such as box; cause protected object to be stolen or conversion; being applied to must be by the equipment or the article of particular department or enterprise's sealing; as ammeter; water meter; oil meter; car plate and container etc., be a kind of do not allow unauthorized people adopt and forge or take only to destroy the coupling part can change lead sealing method and the device that object of protection is stolen with leaving no trace.
Background technology
In the conventional art, ammeter, water meter etc. or their assembling casing adopt the method for lead sealing to protect usually, directly couple together as passing by metal or nylon ropes by lead button by its two ends after the upper and lower covers of envelope body, can leave a trace when the person opens without approval as tackling gauging table or gauging table case quilt with this, be convenient to the supvr and can find rapidly by this whether metering method is transformed, in addition, also be applied to other occasions, as reaching a standard etc. in the strange land after the container lead sealing of customs inspection.This method and apparatus that adopts plumbous only sealing quilt envelope body, also there is following drawback in actual use: the one, metallic lead matter is soft, and its shape changes easily, is easily restored after splicing ear is pulled out, the lead sealing of restoring is difficult for being found, and is difficult to stop the problem appearance that object of protection is stolen; The 2nd, to copy easily for plumbous, the change back only also is difficult for being found by the supvr with the original lead of the plumbous only replacement of imitation, is prone to the forgery of mixing the spurious with the genuine.
Content of the present invention
Lead sealing method of the invention and device, plumbous only have one can be false proof sign, this sign has the pattern of contrast, for carry out true and false discriminating in the future.
Lead sealing method of the invention and device also have further thief-proof effect with the part that lead only is connected, and change the possibility of equipment to prevent the stealer by destroying other parts, thereby make the thief-proof effect of lead sealing method and device obtain further perfect.
Particularly; lead sealing method of the invention and device; adopted a metal shell that the silk rope that is used for provision for sealing is protected; the silk rope passes and is packaged in this metal shell behind the position, upper and lower covers hole of envelope body; can play the effect that packed silk rope section is protected; help solving that line end is easily destroyed is difficult for found problem, show its feature.
Further, lead sealing method of the present invention and device, be packaged in the silk rope section in the metal shell, can offer a kind of means of supvr, by checking whether its termination or end can be moved, can help the supvr to judge whether to exist the stealer to change the possibility of equipment, the silk rope that has solved place, shell mesopore position is cut off conversion easily and reconnects the deficiency that only can rely on naked eyes to find, has further characteristics again.
Therefore, at first, the objective of the invention is to provide a kind of false proof, thief-proof lead sealing method that has, this method not only can only recognize true and false by lead, and can recognize that the stealer destroys the possibility that other parts are changed equipment by checking with the plumbous part that only is connected.
Secondly, the objective of the invention is to provide a kind of false proof, thief-proof sealing device that has, this device not only can only recognize true and false by lead, and can recognize that the stealer destroys the possibility that other parts are changed equipment by checking with the plumbous part that only is connected.
Its purpose is realized by following scheme:
A kind of lead sealing method, only seal an end head by a rhizoid rope through quilt envelope body position, upper and lower covers hole and by a lead, the sign only surperficial by lead carries out false proof discriminating, be characterized in, two terminations of described silk rope or termination are connected the aperture on the metal shell that bend also seals through one one end respectively and are trapped in the described metal shell with one, the termination that will be trapped in the described metal shell by stopper is limited, and by described lead only with described termination or connect bend and be enclosed in the described metal shell inside, with moving of the described silk end head that is enclosed in described metal shell as thief-proof identification key.
Like this, because two terminations of silk rope, perhaps a termination is connected bend with one, be packaged in metal shell inside, the stealer must destroy metal shell earlier, and metal shell has only better intensity than lead usually if will or connect bend from the termination starts with, be difficult to after destroyed restore, can leave a trace and easily be found.
Importantly, be encapsulated in the termination of metal shell inside, certain surplus can be arranged, can be moved, this characteristic can be used to further thief-proof, prevents that adopting viscose glue that the termination is stained with subsequently the termination cut-out from metal shell is difficult for the found method of stealing, owing to be not easy control with the viscose glue adhesion, be easy to also stick together at place, position, hole, at this moment the termination will no longer can be moved, and can allow the supvr in time note abnormalities.
In addition, utilize to be moved between silk end head and the metal shell and to assert that its normal mode and traditional habit are outstanding apparent different, it provides a kind of can be used for preventing that the stealer from may change the thief-proof method of equipment by destroying other parts.
Thus obtained lead sealing method; restricting especially with the silk that lead only is connected, the termination is encapsulated in metal shell inside and has been subjected to protection; plumbous also has been subjected to protection owing to be pressed into metal shell inside; this comes false proof true and false particularly important for seal literary composition that relies on plumbous only surface, can make Yin Wen avoid being clashed into or rub and keep original shape in order to inspection.
Moreover, because can distinguish whether there is the problem that is cut off stickup by checking it be moved between silk end head and the metal shell, therefore, not only lead be only with false proof, also can be used to thief-proofly with other parts that lead only is connected, method has obtained sufficient perfect.
In the said method, described connection bend is to adopt by another termination of described silk rope through the protruding rope section that is trapped in metal shell inside of two other aperture of described metal shell.
Be more preferably, in the said method, described silk rope is wire strands, its another termination system passes an aperture from outside to inside after bending, the free end that stretches out thus bending more also passes another aperture from inside to outside and stretches out, by pulling out free end, can allow the silk rope described connection bend between two apertures tighten, can not be moved separately, can be compressed and be moved simultaneously with each end at described connection bend two ends as thief-proof identification key with these two ends.
Thus obtained method, a kind of mode of operation more easily can be provided, because stopper can be loaded onto in advance in factory in an end of wire strands, another end of wire strands can offer carries out perforation procedure when the user constructs at the scene, and need not install another stopper again, utilize metal being retained in around property and with sweep among two holes of sweep between other positions, two holes simultaneously, thereby obtained a kind of not only simple to operate but also also simple method of lead seal structure.
In addition, the stealer is if attempt to cut off the part that the connection bend is exposed to place, position, hole, then can making broken end be difficult for leaving the position, hole and can't be in subsequently another broken end be connected to and do not leave a trace in the metal shell owing to the wire strands sweep around property, simultaneously also since the wire strands sweep around property, the situation that the at one end not mobile other end can be moved can not be deposited in the two ends that connect bend, if moreover the two ends that connect bend are compressed and draw in and moved simultaneously, then it can be shifted.
Can not be moved separately, can be compressed and be moved simultaneously as thief-proof identification key by each end that connects the bend two ends with these two ends, can play further thief-proof effect, it is in a single day destroyed and form the situation of flange in its end with viscose glue to prevent to connect bend, when viscose glue is failed end and position, hole fixedly, two ends that connect bend all can be moved separately, and when viscose glue with end and position, hole fixedly the time, the two ends that connect bend can not be compressed to be drawn in and can not be shifted, and steals and can be recognized thereby make.
Two terminations of above-mentioned silk rope are encapsulated in the method for metal shell inside, and further thief-proof effect all can be played in two terminations.
Be more preferably, in the said method, be attached with on envelope body or the sealing device one with its corresponding codes, this coding is stored in the computer system data storehouse of telephone network or internet with the information of a lead surface marker, can the strange land transfers for the user and verifies the true and false for information about.
In the said method, described stopper can be the knot that is formed by end, also can be other parts, and these parts can be the fixtures of porose position, and as nut or the flange that is made of plastics etc., this fixture is fixed on the termination of silk rope by the position, hole.
In the said method, the hole-shaped on the described metal shell is formed on the metal shell blind end.Like this, can make that perforation procedure is easier, especially be retained in the part between enclosure interior two holes, can easily realize under by the free end effect of stretching out crooked and tighten.
Be more preferably, in the said method, the inside and outside ladder that forms of described metal shell makes little top, bottom big, and the lead that enters in the described metal shell with the restriction compressing only only is in the place, top.This method can guarantee that enclosure interior keeps certain surplus space, guarantee silk end head or connect bend only not contact with lead, the thief-proof interaction energy that the termination can be moved accesses assurance, and simultaneously, outer step also can be the plumbous operation only of instrument compressing a stressed step is provided.
Be more preferably, in the said method, described lead only also is formed with corresponding ladder, makes lead little bottom only can enter the interior bottom of metal shell, and plumbous big top only is constrained to lie on the interior ladder.Thereby the further space of restricted surplus makes the displacement of termination obtain restriction, control do not allow its excessive and to the stealer stay change may.
Be more preferably, in the such scheme, a metal washer also is equipped with in described lead bottom only, this metal washer is positioned on the ladder of described metal shell, this metal washer can concentrate on the power of suppressing a plumbous top, make upper deformation and crowded, and can guarantee that the bottom is near silk end head or connect bend but do not contact with them at the inwall place of metal shell.
Be more preferably, in the said method, the sign of described lead on only ties up to described lead and only forms concavo-convex picture and text in the surface by punching block at described lead when only being suppressed into described metal shell inside.Produce when plumbous quilt suppressed metal shell inside owing to punching block ties up at a lead surface formation picture and text, thus obtained anti-counterfeiting information has the influence that more excellent accuracy, particularly graph text information no longer are subjected to the process of oppressing, thereby can not cause confusion reigned.
In addition, the end face of the lead through suppressing is absorbed in the metal shell, therefore, not only anti-false sign produce simple to operate, and the anti-false sign of a plumbous end face also is protected, and is difficult for the difficulty because of easily causing anti-false sign to recognize with external world's friction.
Be more preferably, in the said method, adopt described lead only in the point of its profile of picture and text, the different depth on surface and the described lead surface impurity color and luster depth as anti-false sign.
Be more preferably, in the said method, take from individual's writing as the only surperficial picture and text of the described lead of anti-false sign, its strength of current and engraving number of times changed when the profile of writing, the degree of depth and the impurity color and luster depth can be processed described punching block by laser head by adjusting.
In the said method, the surface of metal shell also can be printed on anti-false sign.Be used for preventing that with the only surperficial anti-false sign of lead the counterfeit producer from providing same device and evading gerentocratic supervision to the stealer.
Like this, in the inventive method, the plumbous only Antiforge on surface depends on the personnel of the signer that produces person's handwriting, selected laser head working current intensity and the wright that engraving is made the punching block number of times, the former has determined the tendency of font, both have determined the depth of font the back, therefore, the common ground of sign depends on different personnel and can form mutual restriction; Moreover Antiforge also can be taken from the plumbous only impurity on surface simultaneously, because impurity has and plumbous different color and luster, and the position of a different plumbous impurity and varying in size, make that the impurity in indicating has randomness, can become particular.In addition, false proof can be to recognize at lead common ground only, and this identification has specific and characteristics fast, also can be to recognize to have unique trait at lead particular only simultaneously, plays the false proof effect of further reinforcement.
In addition, because anti-false sign is to constitute picture and text with a lead concave-convex surface each point, each point is in the different levels, and only be hidden in the metal shell with lead, therefore, attempt the complete extraction anti-false sign so that it is difficult making same punching block, especially all the more so when the color and luster of concavo-convex picture and text and impurity mixes in one.
A kind of sealing device, comprise that the lead that there is a sign on a rhizoid rope and surface only, it is characterized in that, two terminations of described silk rope, perhaps a termination is connected bend with one, be trapped in the described metal shell via the aperture on the metal shell of one one end sealing, and the stopper that described termination is limited to inside, position, hole is arranged, and can only they be encapsulated in the inside of described metal shell by described lead.
