Abstract

The invention relates to a voltmeter with a protection function. The voltmeter comprises a casing, a clamping mechanism, a display screen, a protection board, a protection mechanism and two sliding rails, wherein the protection mechanism comprises a lifting assembly and a clearing assembly; the lifting assembly comprises a positioning rods, a driving unit, an expansion bracket, a connecting plate,two sliders, two support plates, two connecting blocks and two driving blocks; the clearing assembly comprises a reciprocating unit and a clearing block; the clamping mechanism comprises a first motor, a positioning block, a support block, a fixing block, a guide assembly and two clamping assemblies; each clamping assembly comprises a lead screw, moving blocks and clamping plates. According to the voltmeter with the protection function, the protection mechanism is used to play a protection role in the display screen; besides, an ash clearing effect on the display screen can be realized, so that the voltmeter has higher practicability; the casing is fixed on the edge of a desk through the clamping mechanism, accordingly, the voltmeter is more convenient to use, and the convenience of the voltmeter is improved.

Description

technical field [0001] The invention relates to the field of smart grid metering instruments, in particular to a voltmeter with a protection function. Background technique [0002] A voltmeter is an instrument for measuring voltage. Consists of permanent magnets, coils, etc. The voltmeter is a fairly large resistor, ideally considered an open circuit. [0003] The existing voltmeter displays various values ​​through the display screen during use, and the display screen is exposed to the air and is easily damaged, which will cause the voltmeter to be inconvenient to observe, thereby reducing the practicability of the existing voltmeter, not only In this way, when the existing voltmeter is used, it is inconvenient to place it, and the convenience of the existing voltmeter is greatly reduced. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a voltmeter with protection function in order to overcome the deficiencies...
