Water meter

Abstract

The water meter comprises a water meter shell, a water inlet, a water outlet, a first water conveying pipe and a second water conveying pipe, the water inlet and the water outlet both communicate with first connecting pipes, the first water conveying pipe and the second water conveying pipe both comprise second connecting pipes, and sealing assemblies and pre-positioning assemblies are arranged between the first connecting pipes and the second connecting pipes; and the outer side walls of the first water conveying pipe and the second water conveying pipe are fixedly sleeved with connecting rings. The two ends of the water meter shell are provided with fixing devices used for fixing the two connecting rings. Each group of fixing device comprises two limiting blocks which slide oppositely or oppositely and a driving mechanism which is arranged at one end of the water meter shell and is used for driving the two limiting blocks to move; the ends, away from the driving mechanism, of the two limiting blocks penetrate through the two connecting rings correspondingly; and limiting mechanisms used for limiting the limiting blocks are installed at the ends, away from each other, of the two connecting rings correspondingly. The water meter shell is convenient to install.

Description

technical field [0001] The present application relates to the technical field of water supply equipment, in particular to a water meter. Background technique [0002] At present, a water meter refers to an instrument for measuring water flow, and an instrument for recording the water consumption of tap water. [0003] Related technologies can refer to the Chinese utility model patent with the authorized announcement number CN210689746U, which discloses a water meter, including a water meter housing, a water inlet, a water outlet, a first water delivery pipe, and a second water delivery pipe. The water meter housing is provided with a convex surface The mirror can reflect the reading area on the dial with the largest area. At the same time, because the convex mirror has a certain protruding radian, the user can also see the image in the mirror when observing the mirror sideways, making reading more convenient. Under low temperature conditions, The freezing of the water meter...
