Embodiment
Embodiment of the present utility model is as follows.
As shown in figure 1, the utility model provides a kind of outlet tube fixing mechanism of gas meter, flow meter, including shell 1, escape pipe 8
With sealing 9, the shell 1 is provided with the opening for being used for wearing the escape pipe 8, and the sealing 9 is fixed on the upper end of escape pipe 8
Portion.
The utility model mainly also includes first flange 2, second flange 3 and tight loop 12, and the first flange 2 is located at out
The lower end of tracheae 8, the second flange 3 is located at the lower end of first flange 2, lower end and the second flange 3 of the first flange 2
The first sealing ring 4 is provided between upper end, the second sealing ring is provided between the inwall of the first flange 2 and the outer wall of escape pipe 8
7, bending edges ear 10 is additionally provided with the escape pipe 8 at the opening of shell 1, and the shell 1 is provided with and the phase of bending edges ear 10
Corresponding bending section 11, the bending section 11 is located at the outside of bending edges ear 10, and the tight loop 12 is set in bending section 11
Outside, is provided with the 4th sealing ring 14, is set between the shell 1 and bending edges ear 10 between the escape pipe 8 and bending edges ear 10
There is the 3rd sealing ring 13.
In order that the cooperation of first flange 2 and second flange 3 is more firm, the lower end outside of the first flange 2 is provided with card
Provided with the fixture block 6 being engaged with neck 5 on the outside of groove 5, the upper end of the second flange 3.
The utility model when in use, first coordinates escape pipe 8 through opening posterior end, second flange 3 with first flange 2
Fixture block 6 be stuck in neck 5, then tight loop 12 is set in the outside of bending section 11, now due to the effect of four sealing rings,
On the one hand escape pipe 8 is preferably fixed on to the inside of shell 1, sealing property is on the other hand greatly improved.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, under the premise of the utility model design spirit is not departed from, this area ordinary skill technical staff couple
