Mechanical water meter capable of automatically opening water meter cover

Abstract

The invention discloses a mechanical water meter capable of automatically opening a water meter cover. The mechanical water meter structurally comprises a double-end screw pipe, locking nuts, detection connectors, the water meter cover, a meter cover assembling head, a water meter display machine body and a water meter detection machine body, wherein the top end of the water meter detection machine body is locked with the water meter display machine body and the middle part of each of the front end and rear end of the water meter detection machine body is vertically welded with one end of thecorresponding detection connector; the two detection connectors are arranged; the other ends of the detection connectors are locked with the double-end screw pipe through the locking nuts; the water meter display machine body is a cylinder; the right end of the water meter display machine body is locked with the meter cover assembling head and is buckled with the right end of the water meter coverthrough the meter cover assembling head; the left side of the top end of the water meter display machine body is buckled with the water meter cover; when a user utilizes equipment, the equipment canbe subjected to cover closing and automatic cover locking through a mechanism composed of a spring, an ejection rod, a gear, a pull rope and the like, so that one-key type automatic cover opening canbe realized; after the cover is opened, the safety of a cover lock and a button can be ensured better so that a lock cover of the equipment is ensured and the equipment is convenient to use.

Description

technical field [0001] The invention relates to a mechanical water meter capable of automatically opening the water meter cover, which belongs to the field of mechanical water meters. Background technique [0002] A water meter is a device that measures the amount of water used. It is common in the user end of tap water, and its degrees are used as the basis for calculating water charges. Water meters usually measure in cubic feet or cubic meters. [0003] The development of water meters has a history of nearly 200 years since the invention of the balance tank water meter with instrument characteristics in 1825 by Cross in England. The use and production of water meters in China started relatively late. In 1879, Li Hongzhang established my country's first water plant in Lushunkou in order to manage the navy. In 1883, the British colonialists established a second water plant in Shanghai, and water meters began to enter China. As some coastal cities built water plants one...
