Description

Technical Field

[0001] The utility model belongs to the technical field of gas meters, and in particular relates to an intelligent integrated gas meter. Background Art

[0002] At present, smart gas meters are becoming more and more popular, and the market ownership is increasing year by year. They are slowly replacing some old non-smart gas meters. Although the number of smart gas meters is increasing year by year, the assembly is complex and time-consuming during the manufacturing process, and the factory production cost is high.

[0003] Smart gas meters use smart modules to operate the gas meter. If water enters the smart module, the gas meter will not work properly. Now more and more gas meters are used outdoors, so the waterproof performance of the smart gas meter shell is very high. The main components of the smart gas meter on the market are generally in the form of a cover + button + base + base meter, and then the sealing is achieved in the following ways:

[0004] 1. A seal is achieved between the sealing gasket of the base and the base surface;

[0005] 2. The base and the cover are sealed by the water guide groove or foam glue between the cover and the base;

[0006] 3. The buttons are sealed by waterproof silicone buttons;

[0007] Too many seals will greatly increase the protection level failure and other problems. At present, gas meter users are often reluctant to close or forget to close the door cover after replacing the battery, resulting in the battery box being partially exposed. Once the battery box is flooded, the gas meter will be flooded, causing the intelligent module to fail and the gas meter to be damaged. This makes the proportion of the intelligent module of the ultrasonic gas meter in the gas meter very important.

[0008] In view of the above problems, it is necessary to improve them. Utility Model Content

By cooperating the base meter component, the face cover component, the gas meter intelligent module, the power module, and the door cover component, the highly integrated structure of each module can reduce the number of gas meter parts. At the same time, the face cover component will integrate the intelligent module and the power module, and the base will be eliminated, which can also reduce the total volume of the smart gas meter (occupying less installation space for customers); it can also reduce the production and assembly processes and improve the product protection level; the physical buttons are replaced by touch buttons, completely avoiding the problem of button leakage.

[0042] A longitudinal rib 21 is formed in the middle of the sealing pressing rib 20, and the longitudinal rib 21 is used to divide the gas meter intelligent module 3 and the power module 4 into two independent compartments, so as to avoid the influence of the gas meter intelligent module 3 when the power module 4 is partially flooded.

[0043] A positioning groove 22 is formed on the longitudinal rib 21, and a wire plug 9 is installed on the positioning groove 22; an electric wire 24 is inserted into the wire plug 9, and the two ends of the wire 24 are respectively connected to the gas meter smart module 3 and the power module 4; the wire plug 9 is arranged to be clamped on the positioning groove 22, and the wire plug 9 is made of flexible plastic material. A through hole is formed in the wire plug 9, and the through hole is used for the wire 24 to pass through, so that the sealing of the entire longitudinal rib 21 is complete.

[0044] The gas meter intelligent module 3 includes a patch board 31, a liquid crystal display 32, a touch button 33, a socket 34 and a needle header 35; wherein the liquid crystal display 32 and the touch button 33 are assembled on one side of the patch board 31, and the socket 34 and the needle header 35 are assembled on the other side of the patch board 31; the socket 34 is connected to the power module 4 to obtain power, and the patch board 31 is fixed to the surface cover assembly 2 by screws.

[0045] In this embodiment, a plurality of studs 25 are arranged circumferentially on the surface of the face cover assembly 2, and the plurality of studs 25 are all located outside the groove 10. The plurality of studs 25 are fixed corresponding to the mounting holes, and the base meter assembly 1 uses a pin 26 to connect with the pin header 35 of the gas meter smart module 3 to complete data collection and valve control.

[0046] Two pins 26 are installed on the cover assembly 2, and the pins 26 are connected to the pin socket 35 of the gas meter intelligent module 3 to read information; a transparent window 27 is installed on the cover assembly 2, and the liquid crystal display screen 32 is arranged corresponding to the transparent window 27.

Even if the user forgets to close the door cover after replacing the battery, the independent waterproof sealing performance of the power module 4 can ensure the working environment of the battery.

[0055] The inner wall of the door cover body 50 is provided with circumferentially arranged positioning grooves 53, and correspondingly, the surface cover assembly 2 is formed with positioning ribs 13 corresponding to the positioning grooves 53; the positioning ribs 13 are located outside the cavity 28, and when the door cover assembly 5 is closed, the positioning ribs 13 are embedded in the positioning grooves 53.

[0056] The utility model forms a waterproof layer among the door cover assembly 5, the cavity 28 and the power module 4 by setting the mutual cooperation between the positioning rib 13 and the positioning groove 53, which not only provides waterproof sealing performance, but also prolongs the service life of the power module 4, and the power module 4 is easy to replace as a whole; the utility model is cleverly designed, and the power module 4 can be detachably assembled in the cavity 28, which facilitates the replacement of the entire cavity 28.
