Description
Technical field
The utility model is related to gas meter, flow meter field, the sealing structure of exocoel in more particularly to a kind of gas meter, flow meter.
Background technology
Probably there are two types of modes for the sealing structure of exocoel in gas meter, flow meter currently on the market：
Method one：By on diaphragm apply one circle fluid sealant be then formed by curing cushion rubber by diaphragm pressing plate compression lead to again
Cross the sealing of exocoel in ultrasonic bonding or thermofussion welding realization.
Method two：By existing cushion rubber, diaphragm, diaphragm pressing plate, then inside and outside being realized by ultrasonic bonding or thermofussion welding
The welding of chamber.
This two ways increases diaphragm pressing plate, and cushion rubber (or gluing) also has ultrasonic equipment, and solving, gas meter, flow meter is close
The input of the raw material of gas meter, flow meter is virtually increased during envelope, ultrasonic bonding or thermofussion welding increase equipment investment
With artificial input.This mode can guarantee the stability of sealing really but considerably increase the material cost of gas meter, flow meter with manually into
This.If the unqualified entire main body destruction of product can not repair simultaneously.
The information for being disclosed in the background technology part is merely intended to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implies that information composition has been existing well known to persons skilled in the art in any form
Technology.
Utility model content
The purpose of this utility model is to provide a kind of sealing structure of exocoel in simple and reasonable gas meter, flow meter, the combustions
The sealing structure of exocoel increases multiple-sealed line by mechanical structure in gas meter, to realize the sealing of inner cavity and exocoel.Relative to
Current sealing means have saved material cost, improve efficiency of assembling.
To achieve the above object, the utility model provides a kind of sealing structure of exocoel in gas meter, flow meter, in the gas meter, flow meter
The sealing structure of exocoel includes：Diaphragm；Side cover, sealing outer, which replaces, is laid with the first crimping hole and the first crimp column, and
Increase seal convexity at the side cover seal line of the side cover and form first of sealing, the diaphragm has seals what is be adapted to first
First of diaphragm bending and second diaphragm bending；And ontology, sealing outer is alternately laid respectively to be crimped with described first
Hole, corresponding second crimp column of the first crimp column, the second crimping hole, and increase ontology protrusion at the ontology seal line of the ontology
Form second line of seal.
Preferably, in above-mentioned technical proposal, the first crimping hole and the first crimp column totally ten, the second crimping hole, the
Two crimp columns totally ten.
Preferably, in above-mentioned technical proposal, the leading portion of the first crimp column and the second crimp column carries chamfering.
Preferably, in above-mentioned technical proposal, the first crimping hole and the second crimping hole are respectively provided with reinforcement protrusion.
Compared with prior art, the utility model has the advantages that：The sealing structure of exocoel is led in the gas meter, flow meter
Crossing mechanical structure increases multiple-sealed line, to realize the sealing of inner cavity and exocoel.Material has been saved relative to current sealing means
Expect cost, improve efficiency of assembling.
Description of the drawings
Fig. 1 is the structure diagram of the sealing structure of exocoel in the gas meter, flow meter of the utility model.
Fig. 2 is the partial enlargement structural representation of the sealing structure of exocoel in the gas meter, flow meter of the utility model.

Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
Novel protection domain is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figure 1 to Figure 3, according to the tool of the sealing structure of exocoel in the gas meter, flow meter of specific embodiment of the present invention
Body structure includes：Side cover 1, diaphragm 2 and ontology 3, wherein, exocoel is formed between side cover 1 and diaphragm 2, between diaphragm 2 and ontology 3
Form inner cavity.Ontology 3 is installed, and can be real adding two seals line with side cover 1 by crimping hole 14 and the cooperation of crimp column 13
Bore seal between exocoel sealing and 2 component of diaphragm and ontology 3 between 2 component of existing side cover 1 and diaphragm.
Specifically, diaphragm 2 is laid between side cover 1 and ontology 3, and exocoel is formed with diaphragm 2, and inner cavity is formed with ontology 3.
As shown in figure 3, the sealing outer of side cover 1 is alternately laid with the first crimping hole and the first crimp column 5, and in its side cover
Increase seal convexity 9 at seal line 8, form first of sealing 11 with ontology 3, diaphragm 2 has seals be adapted to the with first
One of diaphragm bending 10 and second diaphragm bending 7, this twice bending does not play fold after ensureing diaphragm seal, if producing fold
Meeting poor sealing, and diaphragm fold belongs to defective products.
It is alternately laid respectively in the sealing outer of ontology 3 simultaneously and the first crimping hole, 5 corresponding second pressure of the first crimp column
