Abstract

The utility model relates to an angle drawing rule, which is mainly composed of a lower rule and an upper rule that are mutually overlapped. One end of the lower rule is a circular assembling disc, on which is provided with an annular assembling rail. The surface of the rail is engraved with angle graduation lines. One end of the upper rule is provided with a round pivot rotary disc, a concave assembling groove is arranged on the surface of the rotary disc, and a coaxial annular groove is arranged on the pivot rotary disc. One side of the surface of the rotary disc is provided with a transparent inspection window having index lines for matching with the graduation lines arranged on the surface of the disc of the lower ruler. The angle can be viewed conveniently when the upper ruler is pushed and rotated, and the plotted angle can be adjusted by the pushing and rotating of the upper rule. The locking and positioning can be properly adjusted by a nut which is matched on the coaxial annular groove, and the line drawing work is convenient.

Description

Angle drawing rule

The utility model relates to a kind of Angle drawing rule, for a kind of the be made up of mutually upper and lower chi can be for the simple and easy accurate drawing rule tool of the arbitrarily angled drawing use of rotation.

Because the progress of science and technology, the needs of various accurate measurements and figure iso-surface patch, general drafting and measurement at the drawing upper angle, all be dependent on the use of protractor, and with the design of general quantity hornwork, mostly only semicircle the or circular plate body of a tool degree measure stroke measures because of only using during use, and cooperates to get mark ready, again in addition with the chi tool connected draw out the angle of inclination line segment of palpus, no matter when getting mark ready or in ruling, all may produce deviation, and make the line segment angle position of drawing out therebetween to timing, produce great error, not only very inaccurate, more inconvenient operation, and further improved necessity is arranged.

Because commonly use the drawing rule tool in drawing many shortcomings that angle is used, after research improves for a long time, can develop Angle drawing rule of the present utility model eventually, can be really and overcome effectively and use the inconvenient shortcoming of painting the angle instrument always.

Main purpose of the present utility model, be to provide a kind of can simple and easy any translation-angle and directly draw the Angle drawing rule that uses, this Angle drawing rule is easy to use, and can realize the effect of precision drafting.

According to Angle drawing rule of the present utility model, include two upper and lower chis that splice mutually, wherein: an end of following chi is provided with a circular combination order, the disk body contour is provided with the reticule of degree measure stroke, organize in the top of following chi and the pivot disc that also is provided with a circle in last chi opposite end is folded, making chi can combination order be that commentaries on classics is dialled in the axle center, and the fit angle reticule is stipulated group gyration and drawn.

Described Angle drawing rule wherein plays the combination order of chi to be provided with the combination rail of protrusion, and upward is provided with recessed combination slot relatively on the chi pivot disc, for the assembling of splicing mutually.

Described Angle drawing rule is wherein gone up on the card of chi and is preset with coaxial annular groove one, and is cooperated by the bottom surface of chi down and to wear group with a bolt, and sealed fixing with nut by last chi end face, the supplier is just directed, and line is used.

The splice center of assembling of described Angle drawing rule, wherein upper and lower chi is provided with a centre bore that runs through relatively, and is convenient for the check and correction of line drawing axle center.

Described Angle drawing rule, the card that wherein goes up chi one side horizontal level is provided with the inspection window that a slice has the magnifying glass effect, and draw on transparent window face an index line is arranged, and the supplier just checks scale.

For further specifying structure of the present utility model, feature and practical purpose thereof, describe in detail with reference to the accompanying drawings as the back:

Fig. 1 is stereoscopic figure of the present utility model;

Fig. 2 is a stero exploded view of the present utility model;

Fig. 3 is a combined planar schematic diagram of the present utility model;

Fig. 4 is a compound section schematic diagram of the present utility model;

Fig. 5 is the floor map that use of the present utility model is implemented.

Angle drawing rule of the present utility model, please cooperate and consult shown in Fig. 1-3, whole Angle drawing rule tool mainly spliced mutually by chi 20 on the chi 10 and once and forms a complete Angle drawing rule, wherein play chi 10 1 ends to be provided with a combination order 11, be one to be 270 ° disk, be convexly equipped with a ring-type combination rail 12 coaxial on the card with combination order 11, on combination rail 12 rail levels that protrude except that being carved with reticule 16, omit tool dimpling shape in the periphery of track, in order to making up mutually with last chi 20, and in rail level one side appropriate location by the default flake counterbore 151 in bottom surface, as shown in Figure 4, bottom surface after guaranteeing to make up is smooth, and is preset with cent(e)ring centre bore 14 in the center of combination order 11.

In addition, the chi 20 of going up of the present utility model, one end is set as the higher pivot disc in bottom surface 21, and be provided with the recessed combination slot 22 of a ring in the bottom surface of this pivot disc 21, protrusion combination rail 12 with respect to following chi 10, and the circumferential groove avris in combination slot 22 also slightly is the nick shape, so that splice mutually when assembling with following chi 10, but the simple combination location.The center of going up chi 20 in addition also is provided with the centre bore 24 that runs through, proofread and correct conveniently for inspecting, and be the needs of asking fixed angle, ring is with respect to the position of preset on 12 on the following chi 10 combination rails by the flake counterbore 151 of bottom surface in pivot disc 21 cards of last chi 20, offer coaxial annular groove 25 one, and by after the bottom surface cooperation of chi 10 is upwards worn group with a bolt 15 down, and sealed fixing by the end face of last chi 20 with nut 23, with convenient directed line use.In addition for making things convenient for checking of graduation mark, be provided with the inspection window 26 that a slice has the magnifying glass effect in the card of last chi 20 1 side horizontal levels, and on transparent window face, draw an index line 28 is arranged, the supplier just checks scale.

Whole the Angle drawing rule that combination is finished, when line drawing uses, please cooperate shown in Fig. 4,5 again, because last chi 20 and following chi 10 in the utility model are the L shaped shape designs that are symmetrical, so finish when making up, promptly can form a long chi shape naturally, and on the chi face of long secondary chi, delineation is just like the graduation mark on the vernier scale, so that can accurately and easily use; And when using as angle square, when desire is drawn a specific angle, at first will play the medial surface of chi 10 to be aligned a datum line, or make combination inspect the centre bore 14 of usefulness, 24 are aligned a fixed point, and with the locking nut 23 loosen, to go up chi 20 again and be dialled commentaries on classics, and by the index line 28 on the set inspection window 26 of last chi 20 1 sides, align down the reticule 16 on chi 10 cards, according to the angle of delineation dial forward the location to after, again with after nut 23 locking, the secondary chi that is extended by last chi 20 and following chi 10, can obtain a fixing angle, draw out accurate intersection figure with pen or other scoring tools again, and with the design of Angle drawing rule of the present utility model, its entire combination is simple and easy, during use convenient accurately, the novel drawing rule tool with progressive of can saying so.
