Water meter platform coupler with probing function

Abstract

The invention discloses a water meter platform coupler with probing function. The water meter platform coupler comprises a buffer rubber ring, wherein a plurality of notches are formed in the wall surface in the buffer rubber ring; ring-shaped protrusions are arranged on the two sides of each notch; and the structures of the notches enable the buffer rubber ring and an output shaft of a driving motor as well as the buffer rubber ring and a cylindrical rotating shaft to form detection holes. When the water meter platform coupler is used for carrying out firmness detection on the connection position of the coupler, if the coupler is firmly connected, the detection holes do not appear, and if the coupler is not firmly connected, the detection holes appear; and the buffer rubber ring is of a ring-shaped structure, and the transverse section of the buffer rubber ring is ring-shaped. In combination with other structures, the problem that a coupler in the prior art is often infirm in connection is effectively solved, the defect that whether firm connection exists between the cylindrical rotating shaft and the coupler as well as between the output shaft of the driving motor and the couplercannot be determined in the connecting process is eliminated, and the defect that the tightness degree between the cylindrical rotating shaft and the coupler and the tightness degree between the output shaft of the driving motor and the coupler cannot be explored is overcome.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to a water meter platform with a detection function. Background technique [0002] The development of water meters has a history of nearly 200 years. When selecting water meter specifications, you should first estimate the size and flow range of the flow normally used, and then choose the water meter with the most common flow rate closest to the value as the first choice. Under traditional conditions, the water meter needs to be read manually, and the cover of the meter needs to be opened when reading the meter. Sometimes there is fog or dirt on the glass surface of the meter. Meter reading personnel also do not have special utensils to wipe the glass surface of the meter, which will cause the possibility of misreading. Thus, there is a water meter with the application number "201721803435.5", the application date "2017.12. 21" and the patent name "a water meter". [0003] Th...

Problems solved by technology

[0010] In order to solve the above problems, the present invention provides a water meter platform with a detection function, which effectively avoids the problem of unreliable connection of the coupling in the prior art, and the inability to determine the cylindrical shaft and the coupling during the connection process. Whether there is a firm connection between the drive motor and the output shaft of the drive motor, and the tightness between the cylindrical rotating shaft and the coupling and between the output shaft of the drive motor and the coupling cannot be detected.
