Abstract
The utility model relates to a multipurpose ruler, composed of a ruler, a dial gauge, a pointer and a small circular hole. The utility model is characterized in that one surface with scales of the ruler (1) is craved with the 360 DEG dial gauge (3), a rotary scale disk (4) is embedded in the dial gauge, the pointer (6) is arranged on the scale disk (4) and can vertically indicate DEG numbers downward, and the small hole (2) is arranged under original scales of the ruler (1). The utility model has the advantages of simple structure and convenient operation.
Description
The utility model belongs to teaching aid
Such situation appears in regular meeting in the daily life study: teacher is with a lot of teaching aids figure accurately that but can't draw, and measures angle accurately, classmates' accurate grid that can't draw when going out blackboard newspaper.
The purpose of this utility model is exactly angle, the circle of the different-diameter that draws and the ruler of circular arc that a kind of horizontal linear that can accurately draw on vertical face is provided, draws, measure any size for addressing the above problem.
The utility model is by being made up of the round-meshed ruler of scale and the dial and the pointer that are set on the ruler, its technical scheme of dealing with problems is to punch under certain unit scale in the graduated one side of ruler, be used for the picture circle, engraving the scales of 360 degree at any place, and inlaying another and be carved with dials of 360 degree and vertically downward pointer is inner at any time within it with one side.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1, the utility model integral body and schematic diagram.
Fig. 2, the utility model structural representation.
The utility model is drilled with aperture (2) and does the center of circle with one of them under general ruler (1) scale (5), other any one make radius, different circular arcs just can draw.One of them is vertical with the former scale of ruler (1) (5) to make 360 its 0 scales of degree graduation apparatus (3) in the graduated one side of original ruler (1), in the middle of graduation apparatus (3), bore a hole, be used for applique scale (4), dial (4) can rotate in graduation apparatus (3), in dial (4) center one pointer (6) is installed, and pointer can be rotated arbitrarily.When ruler (1) being attached to when drawing on blackboard or other vertical plane, when pointer (6) points to graduation apparatus (3) zero graduation downward vertically according to self gravity, drawn straight line is a horizontal linear, swing ruler (1) the various angles of just drawing, rotary dial (4) and ruler just can be measured arbitrarily angled on the vertical plane, play the effect that a chi is used more.
The utility model is simple in structure, and is easy to use.
Claims (1)
1, a kind of by ruler (1) and 360 ° of graduation apparatus (3) thereon were set in the 360 ° of dials (4) on the graduation apparatus (3) and were installed on the pointer (6) on the dial (3) and are formed at the aperture (2) that former scale (5) go up to bore a quarter ruler, the dial (4) that it is characterized in that being set on the graduation apparatus (3) can rotate, and the pointer (6) that is installed on the graduation apparatus (3) also can rotate.
