Technical Field

[0001] The utility model relates to the technical field of gas meter counting, in particular to a character wheel counter structure with high reliability. Background Art

[0002] From the outside of the gas meter, you can only see a roller with numbers in a small glass window. The fuel has been transformed from conventional energy sources such as firewood and coal, which are wasteful and polluting, to natural gas, coal gas, and even clean energy such as electricity. When the gas meter counts the gas, a digital wheel counter structure is used for statistics.

[0003] In people's daily life, they need to use gas for their lives. When using gas, they also use gas meters to count the amount of gas used. When counting, existing gas meters generally use mechanical counter wheels to perform counting operations. When installing the mechanical counter wheel, there is a possibility of misaligned installation, and the process is also relatively cumbersome. Therefore, during installation, not only are there too many spare parts to install, the assembly process is relatively complicated, and the installation cost is also high. Moreover, when counting, usually only the transmission ratio of the gear is used to count, which will cause the equipment to be unable to perform more comprehensive measurement.
