Abstract
The utility model relates to a multipurpose angle measuring instrument which belongs to the improvement to the traditional measuring instrument for human body sections. A protractor and a ruler are matched organically to achieve the goal of measuring the human body sections accurately. The utility model is mainly composed of the protractor, the measuring ruler, an angle indicating needle, etc. The utility model is suitable for various kinds of inclined measurement in medical projection and can greatly improve the measuring precision.
Description
This utility model relates to a kind of novel multipurpose angular surveying device, and it belongs to the improvement to traditional human body body layer gauge.It mainly is the purpose that reaches accurate measurement human body body layer angle by organic cooperation of adopting protractor and ruler.It mainly is to be made of parts such as protractor, measurement ruler and angle indicators.
In present medical X-ray body layer and exposure technique, traditional method mainly is to adopt straightforward procedures such as set square, delta-ring and range estimation, the result of Ce Lianging is often because fat or thin, the individual difference in size of human body makes data not accurate enough like this, thus make proper layer and throw according to effect also poor.Especially human body fixing a point in the time of 90 ° is bigger to the measurement error at the measurement of table top vertical height and positions such as chest, waist and pelvis.
The purpose of this utility model provides a kind of novel multipurpose angular surveying device with regard to being to avoid above-mentioned the deficiencies in the prior art part.It mainly is to adopt the reasonable combination of protractor and ruler to realize the measurement of all kinds of body layer angle, and the precision of measurement is improved greatly.It mainly is by protractor, measures ruler and angle indicator constitutes, and it is vertical fixing and putting that its major technology characteristics are to measure ruler and protractor base, and an end of angle indicator then is hinged on the round dot place on protractor base.
Accompanying drawing is structural representation of the present utility model.
The drawing of accompanying drawing is described as follows:
1---protractor base 2---round dot 3---angle indicator 4---protractor 5---protractor scale 6---ruler scale 7---measures ruler
In order to realize better above-mentioned purpose of the present utility model, designer of the present utility model also will with The measurement ruler that vertically put on the protractor base is to be fixed on the protractor, and it measures the scale of ruler Be the outer rim from protractor, and stretch out from large to small.
Come enumeration construction features of the present utility model below in conjunction with drawings and Examples:
In actual design with in making, designer of the present utility model fixes it with convention amount hornwork and conventional ruler with screw or other method, and hinge is set at the round dot place on protractor base, itself and angle indicator are hinged, and the tip of required angle pointer can be done circular arc along the outer rim of protractor and be moved with the indication angle.
This utility model is to design according to geometrical principle, and is scientific and reasonable for structure, is suitable for and the various inclination measurements of throwing in shining, and certainty of measurement is increased substantially.
