Abstract
The utility model discloses an angulometer. A main body is a semicircular transparent plastic board; the middle part of the angulometer is hollowed into a semicircle; the middle part of an arc-shaped ring is provided with an arc-shaped groove which divides the arc-shaped ring into an outer scale plate and an inner scale plate; the lower part of the angulometer is a stripy bottom board in a horizontal state; the middle part of a bottom board is rotatably connected with the bottom end of a pointer; the top end of the pointer is positioned on the outer scale plate; and the upper part of the pointer is connected with an embedding block which is positioned in the arc-shaped groove. Since the inner-layer scale plate and the outer-layer scale plate are arranged and the middle parts of the scale plates are hollowed, the angle of a smaller edge can be conveniently measured; due to existence of the pointer, the angulometer can be used as a right angle in certain range; when the edge is drawn, the angle is measured firstly, then the top end of the pointer is fixed and a pointer rod can become a line-drawing ruler.
Description
Technical field
The utility model relates to a kind of student stationery, particularly a kind of protractor.
Background technology
Existing protractor is a semicircle transparent plastic sheet, is evenly distributed with angle measuring calibration at the edge of its arc.This protractor to less company commander's angle, is measured and is got up to need boost line, comparatively inconvenience owing to only be designed with scale in outer rim.When drawing the angle, to point out the point on the extended line earlier, be aided with ruler then, comparatively loaded down with trivial details.
The utility model content
The purpose of the utility model provides a kind of protractor that makes things convenient for angulation, picture angle.
For realizing above-mentioned purpose, the technical scheme of the utility model is following:
A kind of protractor; Its main body is a semicircle transparent plastic sheet, it is characterized in that: the middle part of protractor is become semicircle by hollow out, is designed with scale on the semicircular arc ring on protractor top; Arc ring middle part has deep-slotted chip breaker, and deep-slotted chip breaker is divided into EXT scale plate and interior scale plate with the arc ring; The protractor bottom is the strip base plate of level, and the middle part of base plate and the bottom of pointer are rotationally connected, and the top of pointer is positioned on the EXT scale plate, and the top of pointer is connected with an abaculus, and abaculus is positioned at deep-slotted chip breaker.
Because scale plate is two-layer inside and outside being, and the middle part hollow out, can be convenient for measuring the less angle of the length of side; Because the existence of pointer can be used as the right angle effect within the specific limits, when drawing the limit; Earlier that angular metric is good, fixed pointers top then, the pointer bar just becomes the setting-out ruler to be used.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, a kind of protractor, its main body is a semicircle transparent plastic sheet; The middle part of protractor is become semicircle by hollow out; Be designed with scale on the semicircular arc ring on protractor top, arc ring middle part has deep-slotted chip breaker, and deep-slotted chip breaker is divided into EXT scale plate 5 and interior scale plate 2 with the arc ring; The protractor bottom is the strip base plate 1 of level, and the bottom of the middle part of base plate 1 and pointer 4 is rotationally connected, and the top of pointer 4 is positioned on the EXT scale plate 5, and the top of pointer 4 is connected with an abaculus 3, and abaculus 3 is positioned at deep-slotted chip breaker.
