Abstract
The utility model relates to a drawing ruler, particularly a geometrical drawing ruler for students' learn. The top side and the bottom side of a crossfoot are respectively provided with corresponding elongated slot of the top side and the elongated slot of the bottom side. A left rule surface is projected and extended with a pin shaft which is pivoted and glidingly matched in the elongated slot arranged at the bottom side of the crossfoot, and the top face of the left ruler is provided with an angular measurement scale layer which uses a pin shaft center as the center. The bottom side of a right ruler is projected and extended with a pin shaft which is pivoted and glidingly matched in the elongated slot arranged at the top side of the crossfoot. The top face of the right ruler is provided with an angular measurement scale layer which uses the pin shaft center as the center. Thus, geometrical figures with different angles and dimensions can be conveniently drawn.
Description
The utility model relates to Combine of ruler and drawing equipment, refers to that especially the student learns the drawing ruler that plane geometry is used.
At present, the angle that a cover set square can only be drawn some special number of degrees, as: 90 °, 60 °, 45 °, 30 ° angles, drawing one section triangle also needs to cooperate with protractor, just can finish picture through shift position repeatedly, especially draw triangle, not only the trouble and also easily make mistakes.
In view of this, the purpose of this utility model provides a kind of novel Combine of ruler and drawing equipment, and it is the relative chi that articulates two band protractors on crossfoot, draws the figure of different angles.
The purpose of this utility model is achieved in that it mainly comprises crossfoot, left chi and right chi, wherein, upper end, crossfoot top side is provided with length scale layer, be provided with on the chi end face of a left side upper and lower length scale layer is set on upper and lower length scale layer and the right chi end face, crossfoot top side and bottom side are offered corresponding top side elongated slot and bottom side elongated slot respectively, left side chi end face protrudes out a bearing pin, and articulate and be slidingly fitted in the bottom side elongated slot of crossfoot, being provided with the bearing pin center on left chi end face again is the angle measuring calibration layer at center; Right chi bottom side protrudes out a bearing pin, and articulates and be slidingly fitted in the top side elongated slot of crossfoot, and being provided with the bearing pin center on right chi end face again is the angle measuring calibration layer at center.
Described crossfoot bottom side is convexly equipped with lower support leg, and described right chi bottom side also is convexly equipped with lower support leg.
Described left chi end face is provided with a chute and the slippery positioning sliding block that closes thereof.
Owing to adopt such scheme: can draw the geometric figure of the different angles and the different length length of side easily, especially the figure of plane geometry.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 the utility model exemplary embodiments schematic perspective view.
Among the figure:
1, crossfoot 11, top side elongated slot 12, bottom side elongated slot
13, length scale layer 14, lower support leg 2, left chi
21, bearing pin 22, last length scale layer 23, following length scale layer
24, angle measuring calibration layer 25, chute 26, positioning sliding block
3, right chi 31, bearing pin 32, last length scale layer
33, following length scale layer 34, angle measuring calibration layer 35, lower support leg
Present embodiment comprises crossfoot 1, left chi 2 and right chi 3, as shown in Figure 1, and wherein:
Offer corresponding top side elongated slot 11 and bottom side elongated slot 12 on crossfoot 1 top side and the bottom side respectively, its upper end, top side also is provided with length scale layer 13, and its bottom side also is convexly equipped with lower support leg 14, and during for picture and left chi 2 bottom surfaces are supported on the conplane desktop.
The end face of left side chi 2 protrudes out a bearing pin 21, can articulate and be slidingly fitted in the bottom side elongated slot 12 of crossfoot 1, be that left chi 2 can rotate and move (by the sliding friction torque location) relative to crossfoot 1, upper and lower length scale layer 22,23 also is set on left chi 2 end faces and is the angle measuring calibration layer 24 at center with bearing pin 21 centers, be provided with a chute 25 and the slippery positioning sliding block that closes 26 thereof at left chi 2 end faces again, for left chi 2 and location, right chi 3 intersections motionless (its intersecting angle is not rocked).
The bottom side of right chi 3 protrudes out a bearing pin 31, can articulate and be slidingly fitted in the top side elongated slot 11 of crossfoot 1, be that right chi 3 can rotate and move (by the sliding friction torque location) relative to crossfoot 1, upper and lower length scale layer 32,33 also is set on the end face of right chi 3 and is the angle measuring calibration layer 34 at center with bearing pin 31 centers, be convexly equipped with lower support leg 35 in its bottom side again, during for picture and left chi 2 bottom surfaces are supported on the conplane desktop.
