Description

Portable angle instrument

Technical field

The utility model relates to a kind of inclinometer of the usefulness of drawing, especially with the semicircle inclinometer, and the portable angle instrument that spline combines with ruler.

Background technology

Current middle school student and pupil, they are the drawing class not, be some basic drawing knowledge in geometry course middle school, at first from painting a little, drawing beeline is painted circle and pointwise trace and is begun, and used drawing instrument is not outer to be ruler, set square, the semicircle inclinometer, curve ruler does not have any association between these drawing instruments, the standalone feature of each tool self, draw Points And lines with ruler or set square during drawing, draw the fixed arbitrarily angled line again of point with the semicircle inclinometer when drawing angle line, even paint simple figure, its process is also very loaded down with trivial details, makes mistakes easily again.For middle school student, in course and exercise, must pointwise depict a certain function curve, this just need determine the two-dimensional coordinate plane rapidly, draw coordinate grid, the process trouble that seems during with above-mentioned independent drawing instrument, and be difficult for accurately wasting time and energy, how the function of some drawing instrument is combined, make drawing work accurate, rapidly, time saving and energy saving, the very natural combination that can expect the drawing instrument function must organically combine drawing instrument for this reason.

Summary of the invention

According to background technology, the purpose of this utility model is to provide one with the semicircle inclinometer, the drawing instrument that curve ruler and ruler combine, it can draw the point of various distances rapidly, the straight line of all lengths, 0 °-360 ° angle straight line, and can determine two dimensional surface space and grid rapidly, carry out the pointwise trace, also can draw the portable angle instrument of some curves.

In order to reach this purpose, the utility model is achieved through the following technical solutions: a kind of portable angle instrument, by X chi (1), Y chi (2), connector (3), spline (4) is formed, wherein, X chi (1) one end is the inclinometer shape, and the other end is the ruler shape, be provided with spline (4) in X ruler section (11) below, Y chi (2) one ends are pointer shape, and the other end is the ruler shape, and the upper surface of X chi (1) and Y chi (2) all is carved with the angle-differentiated and the length lattice of metric system, X chi (1) is connected with connector (3) with Y centre bore (23) by X centre bore (13) with Y chi (2), and Y chi (2) can be done 0 °-360 ° rotation around connector (3).

Because the utility model is with the semicircle inclinometer, spline and ruler combine, and can draw the arbitrary line at 0 ° of-360 ° of angle very easily, can determine the point of any angle in two dimensional surface.If Y chi (2) vertical fixing in 90 ° the time, then can be drawn the grid of two dimensional surface fast, connector (3) can have the Y chi certain flexible optional position of being fixed in, and also available spline is drawn some curves.

Description of drawings

Fig. 2 is the utility model total structure exploded perspective schematic diagram

Fig. 3 is that the utility model Y chi is opened the drawing schematic diagram

Among the figure: the 1-X chi, 11-X ruler section, 12-X inclinometer section, the 13-X centre bore, the 14-X datum line,

The 2-Y chi, 21-Y ruler section, the 22-Y pointer segment, the 23-Y centre bore, the 24-Y datum line,

The 3-connector, 32-nut, 32-rubber washer, 33-cone of tangents bolt, 4-spline

The specific embodiment

By illustrated in figures 1 and 2, the utility model is by X chi 1, Y chi 2, connector 3, spline 4 is formed, wherein, X chi 1 one ends are the inclinometer shape, the other end is the ruler shape, is provided with spline 4 below X ruler section 11, and Y chi 2 one ends are pointer shape, the other end is the ruler shape, the upper surface of X chi 1 and Y chi 2 all is carved with the angle-differentiated and the length lattice of metric system, and X chi 1 is connected with Y centre bore 23 usefulness connectors 3 by X centre bore 13 with Y chi 2, and Y chi 2 can be done 0 °-360 ° rotation around connector 3.

As seen from the figure, the left end of X chi 1 is an X inclinometer section 12, right-hand member is an X ruler section 11, wherein, the straight flange of the straight flange of X inclinometer section 12 and X ruler section 11 forms the X datum line 14 of X chi 1 jointly, and the straight flange of Y chi 2 forms Y datum line 24, and X datum line 14 and Y datum line 24 intersect at initial point 0 jointly, promptly intersect at X centre bore 13 and Y centre bore 23

As seen from the figure, X chi 1 and Y chi 2 are connected by connector 3, wherein connector 3 is by nut 31, rubber washer 32, and cone of tangents bolt 33 is formed, tightness is regulated by nut 31, because the existence of rubber washer 32, X chi 1 and Y chi 2 is had certain flexiblely compress and regulate.The shape of the bolt head of cone of tangents bolt 33 is cone of tangents bodies that the plane is made in truncated cone both sides, and cone of tangents bolt 33 did not rotate in X chi 1 when it can guarantee nut 31 rotations, was convenient to nut 31 and compressed adjusting accurately.

Be also shown in by figure, the thickness of Y chi 2 is thickening degree step, this is can lean on tightly mutually when closed for X chi 1 and Y chi 2, guarantee X datum line and the snap of Y datum line, overlapping, guarantee also that simultaneously the X chi 1 and the lower surface of Y chi 2 contact desktop simultaneously and keep stable, also can see, only in this way construction measure just can make Y chi 2 do 0 °-360 ° rotation around connector 3, and the textural L size that should guarantee is greater than R size (see figure 3).

Illustrated by Fig. 3, the utility model Y chi 2 upward deflects the situation at α angle counterclockwise, and as seen from the figure, the angle between X datum line 14 and the Y datum line 24 is the α angle, along Y datum line 24 angle value shown in the indication on X inclinometer section 12, is the α angle value.If during with Y chi 2 counterclockwise deflection α=90 °, then Y chi 2 and X chi 1 have been formed the 1st quadrant of two dimensional surface, if draw Cartesian Coordinategrid, that is very easily.In addition, Y chi 2 is closed, tighten connector 3, can use as curve ruler easily.
