Vibration-absorptive current measurement instrument

Abstract

The invention discloses a vibration-absorptive current measurement instrument comprising an inner dial plate. A rotating pointer display meter body and an electronic display meter body are connected in series electrically and are installed on the inner dial plate detachably. A safety protection housing is installed around the outside of the inner dial plate; a small penetrating hole is formed in the safety protection housing at the bottom of the rotating pointer display meter body. Besides, damping corner-wrapping pads are installed at corners of the safety protection housing; and an infrared temperature-measuring device is also arranged at the top left side of the safety protection housing. According to the invention, contrast observation can be realized after series-connection combination; and even when accidental falling or collision occurs, internal appliance elements still can work normally. With the small penetrating hole, the rotating pointer display meter body can be used directly without being taken out. When temperature measurement needs to be carried out, the infrared temperature-measuring device needs to be aligned at a to-be-measured position; and then a measuring result can be displayed in real time by a number degree display screen.

Description

technical field [0001] The invention relates to the related technical field of electronic instruments, in particular to an anti-shock type current measuring instrument. Background technique [0002] Ammeter refers to the instrument used to measure the current in AC and DC circuits. In the circuit diagram, the symbol for the ammeter is "circle A". The current value is in "A" or "A" as the standard unit, and the ammeter is made according to the action of the current-carrying conductor in the magnetic field by the magnetic field force. However, the structure and function of the existing ammeter is very single, and it has no ability to measure the temperature of surrounding objects. In the process of physics teaching, students are required to master it, which will be very troublesome. Not only that, the anti-collision ability of the existing current is extremely poor, and the internal components can be seriously damaged if accidentally dropped, which cannot meet the requiremen...

Problems solved by technology

However, the structure and function of the existing ammeter is very single, there is no ability to measure the temperature of the surrounding objects, and it is extremely inconvenient to use. In the process of physics teaching, students are required to master it, which will be very troublesome. Not only that, the anti-collision ability of the existing current is extremely poor. If it is accidentally dropped, it will cause serious damage to the internal components, which cannot meet the requirements of teaching and needs to be improved.
