Description

A kind of combined type measurement seal

Technical field

The invention belongs to the locked technical field of measuring products, particularly a kind of combined type measurement seal.

Background technology

In the prior art, in the locked technical field of water, electricity, gas, wet goods WT-MSR, be example with the electrical metering device, it has two kinds of seal modes usually, specifically is the self-locking measurement seal mode of lead sealing seal mode and band envelope line.

At present, the self-locking plastic shell seal of band envelope line is comprising the clamping close device that seals line and cooperate with this envelope line; Said clamping close device comprises that shell, cover plate, plug spare and plug-in unit partly form; And the embedded stainless steel spring sheet of plug-in unit, shell and cover plate need ultrasonic soldering, and the parts that product is formed are more; Assembling procedure is loaded down with trivial details, and efficiency of assembling is low; In addition, its sealing property is bad, and poor safety performance does not have the anti-preferably performance of opening.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art, a kind of combined type measurement seal is provided, this measurement seal product building block is few, assembles simple and conveniently, and simultaneously its assembling back structure is fastening stable, effectively improves its anti-performance of opening, and is safe and reliable.

In order to reach above-mentioned technical purpose, the present invention realizes by following technical scheme:

A kind of combined type measurement seal of the present invention; Comprise shell, outer plugin and interior fastener; Said outer plugin and interior fastener portion in the enclosure cooperate clamping and shutoff portion in the enclosure, and equal correspondence is provided with through wires hole or the Wire channel in building that supplies Sealed wire to pass on the front of said shell and the front of outer plugin and the interior fastener.

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 present invention; 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 present invention, said card shell fragment is sheet metal or the plastic sheet that designs with interior fastener end one.

In the present invention, 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 invention has the beneficial effects as follows:

(1) measurement seal of the present invention, 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) measurement seal of the present invention; 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.
