Intelligent electric power instrument capable of being assembled and disassembled many times

Abstract

The invention relates to an intelligent electric power instrument capable of being assembled and disassembled many times. The intelligent electric power instrument comprises a display board and an instrument housing, the side, close to the instrument housing, of the display board is provided with a fixing mechanism, the fixing mechanism comprises a fixing component, a telescopic pipe and two fixing blocks, the telescopic pipe is internally provided with a fixing plate and two telescopic units, the telescopic units comprise springs and first slide rods, the inner walls of the two sides of the instrument housing are both provided with openings and cooling units, and the cooling units comprise second driving motors, driving wheels, fixing rods, frames, third slide rods and blocking plates. According to the intelligent electric power instrument capable of being assembled and disassembled many times, assembly and disassembly of the instrument are achieved through the fixing mechanism, damage to the display board and the instrument housing is avoided at the same time, and thus the assembly and the disassembly can be repeated for many times; besides, the blocking plates are driven to move through the cooling units, so that hot air inside the instrument is dissipated through the openings, therefore the cooling effect is achieved, elements inside the instrument can work in an appropriate environment, and the practicability of equipment is improved.

Description

technical field [0001] The invention relates to the field of instrument equipment, in particular to an intelligent power instrument capable of being assembled and disassembled many times. Background technique [0002] The power meter is a kind of energy meter integrating multi-function, remote transmission and data analysis. It has highly technological functional characteristics such as intelligent deduction, electricity price query, power memory, meter reading time freeze, balance alarm, and remote information transmission. After the power meter enters the power information of the recharged power purchase card into the meter, it immediately starts to supply power to the user and performs real-time settlement. [0003] During the assembly process of existing power meters, screws are usually used to connect the watch case and display panel. Although this connection method can realize the fixation of the meter structure, it is necessary to twist the screws on the meter during ...

Problems solved by technology

[0003] During the assembly process of existing power meters, screws are usually used to connect the watch case and display panel. Although this connection method can realize the fixation of the meter structure, it is necessary to twist the screws on the meter during disassembly and maintenance. After operation, the screw is easy to slip, and at the same time, careless operation may cause damage to the display panel and the watch case while tightening the screw. Therefore, this fixing method is not conducive to the multiple assembly and disassembly of the instrument in the later stage. Most of the instruments are in a closed environment. After the instrument has been in operation for a long time, the heat generated by the internal components cannot be dissipated. The gradual accumulation will easily cause the circuit components inside the instrument to work in a high temperature environment, which not only reduces the internal temperature of the instrument. The working life of components will also affect the measurement accuracy of power meters
