Description
Technical field
The utility model belongs to technical field of teaching instruments, is a kind of angel measuring instrument for measuring the elevation angle and the angle of depression in particular.
Background technology
At present, Junior Mathematics people teaches an edition ninth grade volume two to have an inquiry activity, this inquiry activity content allows student measure object height, and what the measuring equipment of prior art generally adopted is height-gauge and GPS laser range finder, and not only price is higher for height-gauge and GPS laser range finder, and be unfavorable for that teaching uses, thus, usually allow student certainly make angular instrument in inquiry activity, the angular instrument precision that student does certainly is poor, be difficult to reach accurate measurement, have impact on quality of instruction.
Summary of the invention
In order to solve the problem, the utility model provides one and can accurately measure, and the angel measuring instrument that can effectively improve the quality of teaching, its concrete scheme is: described angel measuring instrument is by rotary angular measurement dish, angle index, the rotating shaft of angulation dish, hold-down bolt, observation scale, plummet line, vertical rack, plummet, vertical scale, firm banking, adjusting base, adjusting bolt forms, it is characterized in that the upside of adjusting base is provided with firm banking, the downside of adjusting base is triangular in shape is provided with the adjusting bolt that can regulate firm banking level, the lower end of vertical rack is fixed on the middle part of firm banking, the upper end of vertical rack is provided with rotary angular measurement dish by the rotating shaft of angulation dish, in the rotating shaft of angulation dish, the outside of rotary angular measurement dish is provided with observation scale by hold-down bolt, one end of observation scale arranges eyepiece, the other end of observation scale arranges object lens, by observing the eyepiece of scale and object lens can accurate surveying testee, plummet is by the upper end of plummet line vertical connecting support, the two sides of described rotary angular measurement dish is provided with angle index, and the middle part of described vertical rack is provided with vertical scale.
Plummet line described in the utility model, is characterized in that plummet line is when the vertical state of vertical rack, coincides with its vertical scale, in order to determine that vertical rack is in plumbness.
Observation scale described in the utility model, it is characterized in that described observation scale adopts transparent plastics material, the middle part of described observation scale is provided with scale mark, in order to supplementary observation angle.
The beneficial effects of the utility model are that angel measuring instrument structure is simple, easy to operate, accurately can take measurement of an angle, and can effectively improve the quality of teaching.
