[0036] Reference Figure 1and Figure 2 The front end of the housing 2 is fixedly connected to the mounting box 20, which provides a fixed installation environment for the metering device body 1. The bottom end of the metering device body 1 is in contact with the bottom inner wall of the mounting box 20.

[0037] Working principle: When installing the smart gas meter, the operator places the metering device body 1 into the installation box 20. By turning on the motor 3, power is generated to drive the rotating shaft 4, which in turn drives the rotating plate 5 to rotate. The rotation of the rotating plate 5 drives the transmission plate 6 to rotate. Due to the guiding effect of the T-shaped groove 15 on the T-shaped slider 9, the rotation of the transmission plate 6 causes the T-shaped slider 9 to move left and right, which in turn drives the connecting rod 7 to move left and right. The left and right movement of the connecting rod 7 drives the clamping plate 8 to move left and right, thus clamping and fixing the metering device body 1. The left and right movement of the T-shaped slider 9 drives the sliding rod 10 to move... The left and right movement of the sliding rod 10 drives the L-shaped plate 11 to move left and right, which in turn drives the connecting plate 12 to move left and right. The left and right movement of the connecting plate 12 drives the spring 16 to move left and right. The left and right movement of the sliding rod 13, in conjunction with the left and right movement of the spring 16, drives the protective block 14 to move left and right. The left and right movement of the protective block 14 causes the connecting groove 18 to engage with the sealing strip 33 on the metering device body 1, thereby achieving the upper and lower limit of the metering device body 1. The spring 16 provides buffer protection for the metering device body 1 and the sealing strip 33, reducing the impact of external collisions or impacts.

[0038] When the smart gas meter is working, the starting motor 23 generates power to drive the fan blades 24 to rotate, thereby promoting the flow of gas inside the display meter 21. The gas inside the display meter 21 enters the gas collection hood 25 through the vent 22, and then enters the filter box 27 through the transmission pipe 26. The filter plate 28 filters the dust in the gas, and the filtered gas re-enters the display meter 21 through the connection hole 29. This process cleans the dust inside the display meter 21, increases the airflow of gas inside the display meter 21, and provides good heat dissipation for the electronic components inside the display meter 21.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
