Electricity meter-reading device
Technical field
This utility model relates to electrical equipment technical field, is specifically related to a kind of electricity meter-reading device.
Background technology
During the checking meter of electric power, staff needs meter-copy device is directed at table meter pointer, is connect by infrared ray
Receiving the data of table, owing to ultrared sphere of action is limited, thus data need to make between meter-copy device and table meter
Close together, and owing to the installation site that table meter is actual is the highest, staff generally requires during checking meter
Ascend a height operation, this not only lowers meter reading efficiency, and during ascending a height, there is certain potential safety hazard.
Utility model content
The problem existed for above-mentioned prior art, this utility model provides a kind of electricity meter-reading device, this electric power
Meter copying device need not staff to carry out ascending a height checking meter, and staff can be helped quickly to complete operation of checking meter,
Its meter reading efficiency is high.
To achieve these goals, this utility model provides a kind of electricity meter-reading device, including base, connecting rod one,
Connecting rod two, connecting rod three and depression bar, the central area of described base is fixedly connected with column, described connecting rod one upper
End is fixedly installed instrument bracket, the bottom of connecting rod one the most respectively with the left end of connecting rod two and connecting rod three
Left end is hinged, the right-hand member of connecting rod two, connecting rod three middle part hinged with the middle part of the upper end of column, column respectively,
Column, connecting rod one, connecting rod two and connecting rod three enclose parallelogram, and the right-hand member of connecting rod three is flatly provided with
Rotary shaft, the middle part of depression bar is provided with slotted hole, the left end of described depression bar and the bottom of column along its length
Hinged, the middle part of depression bar is set in the outside of described rotary shaft by slotted hole.
In this technical scheme, by making column, connecting rod one, connecting rod two and connecting rod three enclose parallelogram,
Connecting rod one can be promoted to move upward, so that the meter-copy device being positioned in instrument bracket is convenient soon by lower moulded rod
Speed ground, near table meter, i.e. can help staff to quickly complete operation of checking meter, and this electricity meter-reading device is checked meter
Efficiency is high, and need not staff and carry out ascending a height operation, and its safety coefficient is high.
Further, operating depression bar for convenience, the right-hand member of described depression bar is fixedly connected with handlebar, described handle
Bar is arranged in obtuse angle with depression bar.
Further, the movement of this meter-copy device for convenience, lower left side and the right side of described base are each provided with two
Individual road wheel.
Further, in order to make column have stronger load bearing stength, described column with the pin joint of connecting rod two and
And being set with fairlead between the pin joint of connecting rod three, described fairlead is fixed with base by support bar and is connected.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of electricity meter-reading device, including base 1, connecting rod 1, connecting rod 24, connecting rod
35 and depression bar 6, the central area of described base 1 is fixedly connected with column 2, the upper end of described connecting rod 1
Be fixedly installed instrument bracket 7, the bottom of connecting rod 1 the most respectively with left end and the connecting rod of connecting rod 24
The left end of 35 is hinged, the right-hand member of connecting rod 24, connecting rod 35 middle part respectively with upper end, the column of column 2
The middle part of 2 is hinged, and column 2, connecting rod 1, connecting rod 24 and connecting rod 35 enclose parallelogram, even
The right-hand member of bar 35 is flatly provided with rotary shaft 8, and the middle part of depression bar 6 is provided with slotted hole along its length
9, the left end of described depression bar 6 and the lower hinge of column 2, the middle part of depression bar 6 is set in by slotted hole 9
The outside of described rotary shaft 8.By making column 2, connecting rod 1, connecting rod 24 and connecting rod 35 enclose flat
Row tetragon, can promote connecting rod 1 to move upward by lower moulded rod 6, so that being positioned at instrument bracket 7
In meter-copy device easily and fast near table meter, staff i.e. can be helped to quickly complete operation of checking meter, should
Electricity meter-reading device meter reading efficiency is high, and need not staff and carry out ascending a height operation, and its safety coefficient is high.
Operation depression bar 6 for convenience, the right-hand member of described depression bar 6 is fixedly connected with handlebar 10, described handlebar
10 are arranged in obtuse angle with depression bar 6.
The movement of this meter-copy device for convenience, the lower left side of described base 1 and right side are each provided with two walkings
Wheel 11.
In order to make column 2 have stronger load bearing stength, described column 2 with the pin joint of connecting rod 24 and with
Being set with fairlead 12 between the pin joint of connecting rod 35, described fairlead 12 is by support bar and base 1
Fixing connection.
