Abstract
The utility model relates to a sunshade device, and particularly relates to a sunshade device of a measuring instrument. The sunshade device provided includes a sunshade plate (1), a telescoping rod (2), a rotating shaft (3), a set square (4), and a seat stand (5), and the sunshade device is characterized in that the edges of the left side and the right side of the sunshade plate (1) is connected with the upper end of the telescoping rod (2), the lower end of the telescoping rod (2) is connected two corners of the set square (4), the rotating shaft (3) is connected with the center of the set square (4), and the bottom of the set square (4) is connected with the upper surface of the seat stand (5). The sunshade device provided is simple in structure, reasonable in construction, convenient for measurement, less in measured temperature error, and long in instrument service life, and reduces manpower and costs.
Description
Technical field
The utility model relates to a kind of solar protection devices, and what more specifically relate to is a kind of measuring instrument solar protection devices.
Background technology
At present, general measure instrument need to someone shading of holding up an umbrella, labor intensive, and be subject to temperature impact, and the measurement temperature error of generation is large, and the instrument life-span is short.Market is to lack the device that a kind of convenience is surveying instrument sunshade, not can solve sun direct projection while measuring, the problem that instrument temperature is too high.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of measuring instrument solar protection devices, can effectively reduce measurement temperature error, extends the instrument life-span.
For solving the problems of the technologies described above, technical scheme that the utility model adopts is: a kind of measuring instrument solar protection devices, comprise shadow shield, expansion link, turning axle, set square, seat stand, described edge, the shadow shield left and right sides is connected with expansion link upper end, expansion link lower end is connected with two angles of set square respectively, turning axle is arranged at set square center, and set square bottom surface is connected with seat stand upper surface.
Described shadow shield is rectangle, long 40 ~ 60 centimetres, wide 30 ~ 50 centimetres.
Described expansion link maximum height is 80 ~ 100 centimetres, and minimum constructive height is 30 ~ 50 centimetres.
Described turning axle is cylindrical.
The beneficial effects of the utility model:
(1) the utility model is simple in structure, and structure rationally;
(2) be convenient for measuring, reduce to measure temperature error, extend the instrument life-span;
(3) reduce manpower, reduce the cost.
