Electric voltmeter assembling device

Abstract

The invention relates to an electric voltmeter assembling device. The electric voltmeter assembling device comprises a bottom plate, an outer protecting shell and an upper cover plate. A connecting groove is annularly formed in the edge of the top of the bottom plate, first rubber gaskets are installed on the inner walls of both sides of the connecting groove, and through holes are evenly formed in the inner bottom end of the connecting groove; the outer protecting shell is detachably installed on the upper side of the bottom plate through fixing clamps, connecting plates are fixed to the positions, corresponding to the through holes, of the bottom of the outer protecting shell, limiting blocks are fixed to the top ends of the connecting plates, limiting grooves are formed in the joints ofthe connecting plates and the limiting blocks, positioning blocks are evenly fixed to the top of the outer side of the outer protecting shell, a cavity is formed in each positioning block, and a stopblock is fixed to the top of one side of each cavity; the upper cover plate is detachably installed on the upper side of the outer protecting shell. According to the electric voltmeter assembling device, no additional tool is needed, assembling and disassembling are convenient, the maintaining convenience is improved, and the device has high practicability.

Description

technical field [0001] The invention relates to the technical field of electric voltmeters, in particular to an assembly device for electric voltmeters. Background technique [0002] With the continuous development of society and the continuous progress of science, various products continue to innovate and develop more and more convenient for people to use, such as voltmeter, a voltmeter is an instrument for measuring voltage, generally, the shell of a voltmeter The body is a plastic part, and it is packaged by screw connection. The voltmeter assembled by this assembly method is not very practical, and it fails to provide greater convenience for people's assembly work, and the assembled voltmeter is often not firm enough, resulting in The shell will fall off when impacted by general external force. At the same time, due to the poor sealing performance of the assembled voltmeter, the interior of the voltmeter will be kept in a humid state for a long time in a humid environmen...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides an electric voltmeter assembly device, which can solve the problem that the assembled voltmeter is often not strong enough, causing the shell to fall off when it is hit by a general external force, and the assembled voltmeter has poor sealing performance. Poor, in a humid environment, it will cause the interior to be in a humid state for a long time, which will affect the service life of the internal components of the voltmeter.
