Abstract

The utility model discloses a lead seal device, which is composed of a fastener which connects an upper cover and a lower cover through a fastener bore. The utility model has the improvement that lead blocks are arranged in an upper counter bore of the upper cover and a lower counter bore of the lower cover, or the lead blocks are pressed in the upper counter bore of the upper cover. The utility model has the advantages that authorised users can repeatedly disassemble lead seal devices and instruments easily through the lead seal device, unauthorised users who want to open the lead seal device have to destroy the lead seal device and recognition patterns or characters on the end surface of the lead blocks, the recognition patterns or characters destroyed are hard to restore. The utility model has the advantages of good confidentiality, easy theft protection, simple manufacturing process, convenient operation and low cost.

Description

Sealing device

Technical field

The utility model belongs to container closure or the accessory that is used for object or storing material or transportation, especially relates to the lead sealing technology of anti-dismounting.

Background technology

Present common equipment, generally all adopt screw in conjunction with the screw on the shell fixedly the mode of counterbore and bolt encapsulate, but have the specific (special) requirements of a lot of equipment uses now, mustn't carry out illegal dismounting and repacking to it by unauthorized user.In order to prevent that unauthorized user from carrying out illegal dismounting and repacking to it, method commonly used now has two kinds: a kind of is after the product encapsulation, in the method for device housings upper and lower cover seam or screw fixed orifice place stickup fragile paper or laser anti-counterfeit label; Another kind is to pass hole or the ring of keeping somewhere on hole on the purpose made screw nut and the shell earlier with the lead sealing line, inserts in the hole of lead with holes again, uses the method for lead sealing pliers cramping lead then.But the deficiency that these two kinds of methods exist is: paste the method for fragile paper or laser anti-counterfeit label, in use easily because of colliding or rubbing and cause breakage, its responsibility is difficult to judge; Can pass through in addition as methods such as heating, the private opening label also seals again, has reduced confidentiality.Use the method for lead sealing line, lead with holes and lead sealing pliers, comparatively loaded down with trivial details, operation inconvenience, and it is bigger to the restriction ratio of the structure of shell, when product structure design, will should be used as and taking into full account it, in conjunction with the fixing equipment that encapsulates of the mode of counterbore and bolt of the screw on the shell, major part all can't directly be used for already present employing screw.

Summary of the invention

The purpose of this utility model is to provide a kind of new simple, easy to operate sealing device of good confidentiality, technology.

The technical scheme that the utility model adopted is: it connects institute by fastener hole with loam cake, lower cover by fastener and forms, and its improvements are that it all is pressed with lead in the lower counterbore of counterbore on the loam cake and lower cover; Or in counterbore on the loam cake, be pressed with lead.

The beneficial effects of the utility model are by sealing device, to reach authorized user and be easy to realize repeating dismounting sealing device and equipment; And unauthorized user will open and use the equipment of sealing device, then must destroy the identification icon or the character of sealing device and lead end face, and identification icon after destroying or the very difficult recovery of character.The utility model confidentiality is preferable, is easy to realize thief-proof, and technology is simple, and is easy to operate, and cost is lower.

Fig. 2 is the structural representation of the utility model embodiment 1.

Fig. 3 is the structural representation of the utility model embodiment 2.

Fig. 4 is the structural representation of the utility model embodiment 3.

Among the figure 1, loam cake 2, go up counterbore 3, lead 4, fastener 5, fastener hole 6, lower cover 7, lower counterbore 8, nut 31, upper end 41, bolt 42, rivet 43, screw 51, bolt hole 52, rivet hole 53, screw hole

The specific embodiment

Be illustrated in figure 2 as the structural representation of the utility model embodiment 1, when fastener 4 was bolt 41, bolt 41 coupled together loam cake 1, lower cover 6 by bolt hole 51 and nut 8 in the present embodiment; Utilize and be shaped on counterbore 2 on the loam cake 1 this moment, and the lower counterbore 7 that is shaped on lower cover 6 is pressed into lead 3 in counterbore 2 and the lower counterbore 7, makes it and the hole wall closed contact, has promptly constituted present embodiment.

Be illustrated in figure 3 as the structural representation of the utility model embodiment 2, fastener 4 adopts rivet 42 in the present embodiment, and other action principle is with above-mentioned embodiment 1.It is fastening that this external fastening element 4 can also adopt mode such as connecting pin.

Be illustrated in figure 4 as the structural representation of the utility model embodiment 3, when fastener 4 was screw 43, screw 43 coupled together loam cake 1, lower cover 6 by screw hole 53 in the present embodiment; Only being shaped on counterbore 2 on the loam cake 1, lead 3 is pressed in the counterbore 2 in this scheme, makes it and the hole wall closed contact, promptly constituted present embodiment.On lower cover 6, do not make counterbore in this example.

Among above-mentioned all embodiment, on the upper end 31 of employed lead 3, all be carved with identification icon or character.To prevent that the unauthorized personnel from opening privately without permission.

In such scheme, people all are the situations according to actual upper and lower cover, which kind of fastener decision adopts, then according to the connection situation of fastener, decide the encapsulation situation of lead, make it to reach authorized user and be easy to realize to repeat the dismounting sealing device, and unauthorized user to be opened the purpose that equipment after the lead sealing must destroy sealing device.
