Further improvement as above-mentioned technology; Said shell is the both ends open formula; Comprise openend A and openend B; Fastener comprises the core of the card that places shell aperture end A inner termination and place enclosure in said, is provided with to the leading section symmetria bilateralis of said the core of the card two card shell fragments, and said outer plugin medial surface is provided with some grades of card steps that cooperate with the card shell fragment of interior fastener.

In the utility model; Said outer plugin comprises end, base plate and is fixed in two inboard elastomeric side panels of end; The medial surface of said elastomeric side panels is provided with the one-level first card step at least; The termination correspondence of fastener is blocked the openend A of shell in during cooperation, and the end correspondence of outer plugin is blocked the openend B of shell.

Specifically, the first card step of said elastomeric side panels medial surface is a secondary, and certainly, the progression of this first card step can be one-level or more, and it can realize measurement seal preparatory assembling and the process of assembled in various degree.

In order to guarantee closely cooperating between outer plugin and the shell, the front position of said elastomeric side panels also is provided with the fixed side that is fixed in base plate, and the first step face of said fixed side and interior fastener closely cooperates after conflicting.In addition, the outside of said elastomeric side panels is provided with the wild card step, and the interior sidewall surface correspondence of said shell is provided with the second step face that corresponding engaging with the wild card step realizes the outer plugin self-locking.

In addition, the inboard of said fixed side is provided with the card shell fragment of interior fastener and assembles the second card step that cooperates in advance.

In the utility model, said card shell fragment is sheet metal or the plastic sheet that designs with interior fastener end one.

In the utility model, the outside surface of the base plate of said outer plugin posts antifalsification label or radio frequency discrimination RFID electronic tag.

Compared with prior art, the beneficial effect of the utility model is:

(1) the described measurement seal of the utility model, it is less that it forms assembly, and assembling process is simple and convenient quick, and it can also realize preparatory assembling process in various degree, to satisfy different clients' demand;

(2) the described measurement seal of the utility model; Because the card step corresponding matching of card shell fragment and outer plugin through interior fastener; In making fastener and outer plugin in the enclosure portion can cooperate and carry out effective shutoff closely; And cooperate the back outside destroy three to separate again, effectively improve its anti-performance of opening, safe and reliable.
