Abstract
The utility model relates to a multi-purpose drawing appliance, belonging to a drawing instrument. The utility model comprises a right angle plate, a gauge bar, a sector plate and a sleeve spindle. The gauge bar is installed on the right angle plate, and a center fixing bolt is used as the center of the gauge bar. The gauge bar is rotated on the plane of the right angle plate, and the sleeve spindle which is used as a handle is installed near the center fixing bolt. When the gauge bar is rotated, the sleeve spindle are driven to rotate. The rotating angle of the sleeve spindle is about half of the rotating angle of the gauge bar through the indication of the experiment. With flexible use and convenient carryover, a novel drawing appliance is provided for students.
Description
How to belong to drawing instrument with the drawing device.
The design people has applied for practical drawing device (patent No. 89221270.5) and multi-functional drawing device (patent No. 92223725.5) patent respectively at 1989 and 1992, propose collection set square, protractor, compasses, engineer's scale, divider etc. and be the drawing instrument scheme of one, the drawing instrument of provide easy to use, the degree of accuracy is higher, but last two kinds of drawing instrument volumes are bigger, being not easy to the student carries, and, use underaction because the handle of compasses is angle of transformation that utilize set square.
The purpose of this utility model is to design a kind of drawing devices of using flexible, easy to carry, that the degree of accuracy is high that use more.
Design philosophy of the present utility model is, compasses, set square are combined with the shaped form engineer's scale, adds a sleeve as handle at the hand place of pinching of compasses, and deft design uses flexibly, is easy to carry.
Technical solution of the present utility model is, many with the drawing device, it comprises L-square (16), be installed in the gauge bar (17) that has prong or pen core (14) on the L-square, fanning strip (18), special is on L-square, a sleeve (19) that can rotate on the L-square plane also is installed, sleeve (19) is made up of handle (4) and front fork (9), front fork (9) has two-ply up and down, on the lower plywood on the porose protruded stigma (11) that is embedded in L-square, a compressing tablet (8) is connected between center fixation Luo bolt (7) that gauge bar (17) is installed and the protruded stigma (11) that sleeve is installed in addition, top plate is longer slightly than lower plywood, the end takes the shape of the letter U, also have two downward teeth (10) to abut against the both sides of gauge bar (17) in two ends of U-shaped, drive sleeve when gauge bar (17) is rotated also rotates thereupon, L-square (16) is made up of long chi and short chi, and the end of long chi is equipped with prong (1), and fanning strip (18) is installed in the angle of long chi of L-square and short chi.
The end of the long chi of L-square (16) is wedge shape, prong (1) is fixed in the solid needle tray (2) in wedge shape place by Luo bolt with holes (3), fanning strip (18) is fixed on the L-square (16) by screw (6), two edges in the fanning strip curved side respectively have an aperture (5), when fanning strip is fixed on the L-square, aperture (5) near long chi just in time is embedded on the L-square protruded stigma herein, and fanning strip and L-square all indicate scale.
Gauge bar (17) is that transparent material is made, and indicates cross-line (15) above, and its cross section is
Shape, fanning strip are opaque, and tow sides all have scale.
Description of drawings
Accompanying drawing 1 is many floor map with the drawing device
Accompanying drawing 2 is many with drawing device sleeve connection generalized section
Accompanying drawing 3 is the fanning strip schematic diagram
Be a most preferred embodiment of the present utility model below, provide details of the present utility model in conjunction with the accompanying drawings.
As shown in the figure, the drawing devices of using by four most of compositions more, and (16) are L-square, and it has long chi and short chi, and the end of long chi is a wedge shape, and prong (1) is fixed in the solid needle tray (2) at wedge shape place by Luo bolt with holes (3).(17) be gauge bar, one end of gauge bar is installed on the L-square by center fixation Luo bolt (7), gauge bar can fixed bolt (7) be the center, rotates on the L-square plane, and the other end of gauge bar has end intermediate plate (13), solid sheet Luo bolt (12), prong or pen core (14).(18) be fanning strip, fanning strip is marked with the shaped form scale, fanning strip is fixed on the L-square by screw (6), two edges in the fanning strip curved side respectively have an aperture (5), when by the dress fanning strip, earlier aperture (5) is embedded on the L-square protruded stigma herein, use screw (6) fixing again, fanning strip also can make opaque, positive and negative has different scales, the user can select to install the positive and negative of fanning strip as required, so fanning strip has two hole and two holes (5) that are embedded on the long chi protruded stigma that screw (6) is installed of symmetry.(19) be sleeve, sleeve is made up of handle (4) and front fork (9), front fork has two-ply up and down, top plate is long slightly, lower plywood is shorter, lower plywood is porose to be embedded in the protruded stigma (11) of L-square when being used to install, compressing tablet (8) is connected in center fixation Luo bolt (7) and installs between the prominent bolt (11) of sleeve, the top plate end takes the shape of the letter U, and there are two downward teeth (10) two ends at U-shaped, the top plate of front fork (9) was positioned at the top of gauge bar (17) after sleeve was installed, tooth (10) abuts against the both sides of gauge bar, must have a tooth (10) stressed when gauge bar rotates, and sleeve is rotated thereupon.According to calculating and actual sample shows, the angle of sleeve rotation roughly is gauge bar rotational angle and half.
Effect of the present utility model is, multiplex drawing appliance can be used as set square and uses with the compasses of engineer's scale, is that a kind of use is flexible, easy to carry, the much higher drawing appliance of using of the degree of accuracy.
