[0002] A gas meter is a metering appliance for measuring the use of gas. The usual gas meter connection mode is to connect one end to a gas pipeline and the other end to a cooking appliance. When a user uses gas, the gas enters the cooking appliance from the gas pipeline through the gas meter and the connecting pipeline. The general diaphragm gas meter measures the use of gas through a mechanical meter set in the gas meter, that is, the gas pushes the transmission mechanism set in the gas meter to drive a mechanical counter to jump when the gas passes through the gas meter. When the gas stops flowing, the counter also stops jumping. Ultimately, the amount of gas used is determined by the displayed number on the counter.

[0003] The gas meter is provided with an adapter structure for signal connection. The existing design is to install and fix the adapter column with a signal adapter pin on the adapter structure. This design is prone to problems such as falling of the adapter column during transportation and gas leakage due to poor sealing effect of the adapter pin, which affects the normal use of the gas meter.
