Water meter equipment with enhanced firmness

Abstract

The invention discloses water meter equipment with enhanced firmness. A coupler comprises a cylindrical sleeve with two through ends and a buffer rubber ring. The buffer rubber ring is arranged in thecylindrical sleeve with two through ends; one end of a cylindrical rotating shaft and one end of an output shaft of the driving motor are respectively embedded into two ends of the cylindrical sleevewith two through ends; the cylindrical rotating shaft is combined with the cylindrical sleeve with the two through ends through the buffering rubber ring, the buffering rubber ring is of a ring-shaped structure, the transverse section of the buffering rubber ring is in a ring shape, and the ring-shaped protrusions extend outwards according to the section in the center line direction of the buffering rubber ring. The through structure of the cylindrical sleeve with the two through ends is a cylindrical through opening consistent with the center line of the sleeve. Buffer rubber ring is butadiene styrene rubber. The defect that in the prior art, a coupler is often infirm in connection is effectively overcome.

Description

Technical field [0001] The invention relates to the technical field of water meters, in particular to a water meter device with enhanced reliability. Background technique [0002] The development of water meters has a history of nearly two hundred years. When choosing a water meter specification, you should first estimate the size and flow range of the flow rate used under normal circumstances, and then choose the water meter with the most common flow rate closest to this value as the first choice. Under traditional conditions, it is necessary to manually read the water meter. The meter cover needs to be opened when reading the meter. Sometimes there is fog or dirt on the glass surface of the meter. If the fog is too high, the numbers on the meter will be looked down on, leading to misreading. The meter reader also does not have a special appliance to wipe the glass surface of the meter, which will lead to the possibility of misreading. Thus there is a water meter with the appli...

Problems solved by technology

[0009] The structure in which the drive motor is provided on one side of the roller is as follows: the roller is sleeved on the cylindrical rotating shaft in an interference fit, the output shaft of the drive motor is also cylindrical, and the output shaft of the drive motor The diameter of the shaft is as large as that of the cylindrical rotating shaft, and the cylindrical rotating shaft is connected with the output shaft of the driving motor through a coupling. The current coupling often has the problem of unreliable connection.
