Embodiment Construction

[0010] Such as figure 1 shown. The water meter movement includes a cylindrical core base 1, one end of the core base 1 is closed, the other end is open, and there is an edge 2 outside the open end of the core base 1, and a mounting hole 3 is opened in the center of the closed end of the core base 1. The closed end of 1 is also provided with three ribs 4 surrounding the installation hole. The ribs 4 respectively protrude from the outer end and the inner end of the closed end of the core base 1, and the closed end of the core base 1 is divided into three sectors by the ribs 4. A plurality of leaf-shaped frame-shaped protrusions 5 are arranged along the circumference on the edge 2 located outside the open end of the core base 1 .

Abstract

The invention discloses a water meter core comprising a core seat. An edge is arranged at the outer side of the open end of the core seat, and three convex edges are arranged at the closed end of the core seat and respectively protrude at the outer end and the inner end of the closed end of the core seat. The invention is simple in structure and easy to realize and improves the measuring accuracyof the water meter.

Description

technical field [0001] The invention relates to the field of water meter devices, in particular to a water meter movement. Background technique [0002] A water meter is an instrument that measures water flow. Mostly cumulative flow measurement of water. It is generally divided into two types: volumetric water meters and speed water meters. The water pen is installed on the water pipe. When the user releases water, the pointer or character wheel on the watch rotates to indicate the amount of water passing through. The water meter includes a water meter movement, which is installed in the fixed card. The closed end of the water meter movement in the prior art is a flat bottom. When it is installed in the fixed card, if the fixed card vibrates, the water meter movement will vibrate, which will cause counting errors and affect the performance of the water meter. precision. Contents of the invention [0003] The purpose of the present invention is to provide a water meter ...
