Abstract

The invention discloses a convenient-to-mount ammeter which comprises a box. An ammeter body is arranged in an inner cavity of the box, a threaded hole is formed in each of two sides of the box, a threaded column is connected in each of the two threaded holes in a threaded manner, opposite ends of the two threaded columns are fixedly connected with a first retaining block and a second retaining block respectively, the first retaining block is positioned on the left side of the second retaining block, the first retaining block and the second retaining block are positioned on two sides of the ammeter body, and the bottom ends of opposite faces of the first retaining block and the second retaining block are fixedly connected with a first clamping block and the second clamping block respectively. By arranging a storage groove, a spring, a moving block, a first rotating shaft and a hinging seat and through cooperation of a U-shaped groove, the second clamping plate and the first clamping plate, when the moving block slides to the U-shaped groove, the spring ejects the moving block to enable the same to be clamped in the U-shaped groove by leftwards pushing the second clamping plate and rightwards pushing the first clamping plate, so that effect of fixing the second clamping plate and the first clamping plate is realized; the ammeter is convenient to mount, so that maintenance efficiency is improved, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of watt-hour meters, in particular to a watt-hour meter that is easy to install. Background technique [0002] The watt-hour meter is an instrument used to measure electric energy. It refers to the instrument for measuring various electrical quantities. The earliest watt-hour meter was made according to the principle of electrolysis in 1881. Although each watt-hour meter weighs tens of kilograms, it is very It is bulky and has no guarantee of accuracy, but it was still valued and praised as a major invention in the scientific and technological circles at that time, and it was quickly adopted in engineering. With the development of science and technology, in 1888, the alternating current The discovery and application put forward new requirements for the development of watt-hour meters. Through the efforts of scientists, the inductive watt-hour meter was born. Because the inductive watt-hour meter has simple s...
