In use, moisture is easily accessible in controller box in border, controller is caused to make moist, influences stability in use and service life.
Utility model content
In order to solve problems in the prior art, providing one kind being capable of effective lifting controller box leakproofness for the utility model
Can, convenient for the IC card diaphragm gas meter of assembling.
Specific technical solution is as follows: IC card diaphragm gas meter, including controller box, and controller box includes bottom case and lid,
Bottom case is connected with lid, which is characterized in that the bottom case is equipped with annular groove, and annular groove is arranged around bottom case, is equipped in annular groove
Sealing ring, lid have bending part, and bending part is arranged in upside of the ring groove, and bottom and side and the annular groove of the sealing ring connect
Touching, sealing ring have extension, extension stretch out annular groove, the extending part in the first side wall of bending part and annular groove it
Between, annular groove has second sidewall, and second sidewall is higher than the first side wall.
The following are the attached technical schemes of the utility model.
Preferably, after bending part compresses extension, the sealing ring is L-shaped.
Preferably, the bottom of the sealing ring is arc.
Preferably, the top of the extension is arc.
Preferably, the sealing ring in its natural state when, extension towards bottom case interior direction tilt.
The technical effect of the utility model: the IC card diaphragm gas meter of the utility model is able to ascend between cover board and bottom case
Leakproofness, avoid the controller in controller box from making moist, extend controller service life；Furthermore it is possible to convenient for assembling, sealing
It encloses easy for installation.

Specific embodiment
In the following, being further described in conjunction with substantive distinguishing features and advantage of the example to the utility model, but this is practical new
Type is not limited to listed embodiment.
As shown in Figures 1 to 5, the IC card diaphragm gas meter of the present embodiment includes controller box 1, and controller box 1 includes bottom
Shell 11 and lid 12, bottom case 11 and lid 12 connect.The bottom case 11 is equipped with annular groove 2, and annular groove 2 is arranged around bottom case 11,
Sealing ring 3 is equipped in annular groove 2.Lid 12 has bending part 121, and bending part 121 is arranged above annular groove 2, the sealing
The bottom 31 and side 32 of circle 3 are contacted with annular groove.Sealing ring 3 has extension 33, and extension 33 stretches out annular groove 2, described
Extension 33 is located between bending part 121 and the first side wall 21 of annular groove 2.Annular groove has second sidewall 22, second sidewall
22 are higher than the first side wall 21.In above-mentioned technical proposal, when lid is closed with bottom case, the bending part of lid compresses sealing ring, makes
The extending part of sealing ring is obtained between the first side wall and bending part, to make to form sealing between bending part and the first side wall.
Through the above technical solutions, can be formed and be sealed in intersection when lid and bottom case are closed, thus lifting controller box
Leakproofness.In the present embodiment, bottom case 11 has screw hole 111, and the through-hole 122 that screw passes through lid 12 screws in screw hole, to lock
Bottom case and lid.
The present embodiment, after bending part 121 compresses extension 33, the sealing ring 3 is L-shaped, to enable sealing ring
Strong fix is between bottom case and lid.
The present embodiment, the bottom 31 of the sealing ring 3 is arc, to insert when installing sealing ring convenient for sealing ring
Enter in annular groove.
The present embodiment, the top 331 of the extension 33 is arc, thus during the installation process, bending part and extension
When portion contacts, avoid extension cracking impaired.
The present embodiment, the sealing ring 3 in its natural state when (as shown in Figure 4), extension is towards side in bottom case
To inclination.When bending part 121 is not installed, sealing ring is plugged in annular groove 2, and the extension of sealing ring is towards side in bottom case
To inclination.To which after bending part is contacted with extension, extension can be bent and be fastened between bending part and the first side wall,
Improve installation effectiveness.
The IC card diaphragm gas meter of the present embodiment is able to ascend the leakproofness between cover board and bottom case, avoids in controller box
Controller dampness, extend controller service life；Furthermore it is possible to which convenient for assembling, sealing ring is easy for installation.
It should be pointed out that above-mentioned preferred embodiment is only to illustrate the technical ideas and features of the present invention, purpose
It is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly, this reality can not be limited with this
With novel protection scope.All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover in this reality
Within novel protection scope.
