Abstract
The utility model discloses a new multi-function drawing instrument, which is characterized in multi-function, and can be used as a straight ruler, an angle measuring ruler, an arc instrument, and compasses.
Description
The design is a kind of novel drawing instruments of using more, and its characteristics are the many usefulness of a chi, and it can use as ruler, bevel protractor, also can do radian instrument and compasses and use.
Make a general survey of the drawing rule tool of selling on the present market and mostly be single type, use and carry extremely inconvenience.
The design's main purpose is with single chi tool, is improved, and is installed on the ruler, forms a novel multipurpose of carrying and using and draws the chi tool.
The design is manufactured by following method: wide for 4cm, long for printing a semi arch kilsyth basalt on the ruler more than the 10cm, the radius student of this table should be good at 1.5-2cm with chi, instrument can be determined the radius of circular arc table as required with chi, the circular arc table reaches the length of chi tool as required, be printed on an end or the centre of ruler, fixing a narrow little ruler on the center of circle of circular arc table, one end of little ruler is sharp type, aim at the radian number on the circular arc table, the other end is loaded onto one and is movably made the camber clamp, clamp has hole on one side, have above the clamp one can be plug-type pen card, plug-type pen card uses for making bowlder, makes the end that round rule pin is contained in big ruler.
Now doing one according to diagram describes:
Fig. 1, be the expanded view of the design's multipurpose ruler.
With reference to Fig. 1: go up fixing little ruler (4) at the center of circle fixing point (3) that is printed on the radian table (2) on the ruler (1), one end of little ruler (4) is the corresponding radian number that sharp type (5) points to radian table (2), the other end can be done the angle of needs according to the radian number of correspondence, movably make arc card (6) and penholder is gone into to do lining, a hole (7) on the arc card (6) being equipped with one on the little ruler (4), the radian number of tip (5) indication of the little ruler of reference (4), move simultaneously and make the radius that arc card (6) is determined the arc of doing, stroke is moving, just can make the circular arc that to manufacture, this arc is the center of circle with fixing point (3), making the rule pin cap (8) that will be contained in earlier on the big ruler when compasses use unplugs, the rule pin (10) that is hidden in the rule pin cap is extracted, then, rule needle point with aperture (9) the alignment gauge pin (10) on the rule pin cap, buckle rule pin cap, just will advise pin (10) fixes, rule pins (10) can not be swung, again pen card (11) is released forward, be fixed with hold-down nut, can justify according to required radius.
Shortcoming: the device of doing the circle use is unsuitable for installing on the very big chi tool of elasticity such as plastics.
Claims (3)
1, has the little ruler of installing on the big ruler of semi arch kilsyth basalt (4) and make the rule pin (10) that circle uses at one, it is characterized in that little ruler (4) fixes on the center of circle (3) of radian table, corresponding radian is pointed at the tip of little ruler, rule pins (10) are fixed on a top on the big ruler, and on big ruler a rule pin cap (8) with holes are housed.
2, stipulate that by claim (1) the little ruler of installing (4) is characterized in that having a movably plug-type pen card (11) of doing arc clamp (6) and the use of work circle in a band hole, pen card (11) is contained in to move and does on the arc card, will move card (6) and pen by set bolt and block (11) and fix.
3, the chi tool of manufacturing by claim 1,2 regulations is characterized in that the many usefulness of a chi, can make ruler, bevel protractor, radian chi and compasses and use.
