Abstract
The invention provides a pen split drawing rule which comprises a first ruler and a second ruler. The section of the first ruler and the section of the second ruler are two opposite semicircles. Two sides of the first and second rulers are provided with scale marks. A fastener is arranged at one end of the first ruler, and a platform surface is arranged at the other end of the first ruler. The middle of the platform surface is provided with a pinhole. A plurality of positioning holes are evenly distributed on the platform surface around the pinhole. One side of the second ruler is a straight guide surface, and two ends of the side are provided with a clamping notch and a fastener both matching with the fastener at one nd of the first ruler. A rotary guide block penetrates into the pinhole of the first ruler, the bottom of the rotary guide block is provided with a positioning protrusion matching with the positioning hole, and the rotary guide block is provided with a guide groove matching with the straight surface of the second ruler. The pen split drawing rule allows for free rotation in the range of 0-180 DEG and locking at special angle. After the guide groove of the rotary guide block is joined with the guide surface of the first ruler, drawing of lines and parallel lines at various angles is facilitated, and the requirement for portability is met.
Description
Technical field
The present invention relates to the drawing rule in the Graphing of Engineering, specifically a kind of form of a stroke or a combination of strokes dissection type drawing rule.
Background technology
The Graphing of Engineering drawing instrument consists predominantly of: compasses, set square and pencil etc., at present a large amount of sheathing tools is arranged on the market, and various single-piece compasses by improving and inventing are also arranged, but rare improvement and invention on drawing rule.Yet present university's Engineering Students not too is accustomed to using classical suit set square (namely use also and only can use) in Drawing Courses, and the Most students custom is used ruler.Trace it to its cause, the one, there is the student to feel to use two set square picture hell to pays (not asking rigorous), the 2nd, there is the student to think set square occupation of land side, not Portable belt.Therefore, design simple, the convenient various angle lines of drafting of a kind of energy or parallel lines, and portable drawing rule, use necessary for the Engineering Students Graphing of Engineering.
Summary of the invention
The present invention draws for fear of two set squares of uncomfortable use, and set square takes up space and the problem of Portable belt not, specially proposes a kind of form of a stroke or a combination of strokes dissection type drawing rule.
Technical scheme of the present invention is for this reason, a kind of form of a stroke or a combination of strokes dissection type drawing rule, comprise ruler one, ruler two, ruler one is two relative semicircles with ruler two sections, the both sides of ruler one and ruler two are provided with graduation mark, it is characterized in that: an end of ruler one is provided with buckle, and the other end is provided with a flat surface, the centre of flat surface is provided with pin-and-hole, is laid with a plurality of locating holes on the flat surface around the pin-and-hole; One side of ruler two is to face spigot surface directly, and an end is provided with buckle, the other end is provided with bayonet socket; Be installed with the rotary steering piece in the pin-and-hole of ruler one, the bottom surface of rotary steering piece is provided with a positioning boss that cooperates with locating hole, and the rotary steering piece is provided with the gathering sill of facing cooperation with ruler two directly.
Improvement to such scheme is: a plurality of locating holes around the pin-and-hole on the flat surface are to be that 5 ° interval arranges along pin-and-hole circumference angle.
Improvement to such scheme is: ruler one and ruler two complement each other to form the tubular of a circle, put the shape that just can form a pen behind the cap for brush.
Improvement to such scheme is: ruler one and ruler two adopt transparent organic glass to make.
Beneficial effect:
The present invention both can draw as two rulers separately in use and use, also the end face buckle of ruler one can be stuck in the bayonet socket of ruler biend and use as adding long ruler, also ruler one can be cooperated with ruler two, utilize the effect of a plurality of locating holes and positioning boss to realize that the angle of ruler one and ruler two transforms; When ruler one and ruler two forms the tubular of a circle mutually to together the time, put the shape that just can form a pen behind the cap for brush, carry convenient after the use.
During use, the gathering sill on the rotary steering piece is combined with the spigot surface of ruler two, makes it to drive ruler one and move along the spigot surface of ruler two, can realize easily the drafting of various angle straight lines and parallel lines.
A plurality of locating holes are that 5 ° interval arranges along pin-and-hole circumference angle is in order to make the angle of two rulers distincter and clear.
The two ends that are provided with buckle, ruler two at ruler one end are respectively equipped with buckle and bayonet socket, and ruler one buckle and ruler two bayonet sockets dress are closed, and can make ruler one and ruler two be combined into one and add long ruler; With ruler one and ruler two buckles in conjunction with, put the cap for brush and can be used as a kind of small-sized drawing " instrument cases " and use, some compasss for drawing and pencil etc. can be placed in the inside.
The present invention adapts to the drafting of various angles and parallel lines, satisfies portable demand.

The specific embodiment
The present invention is shown in Fig. 1,2,3,4,5,6,7,8,9,10,11,12,13,14.
A kind of form of a stroke or a combination of strokes dissection type drawing rule, comprise ruler 1, ruler 29, ruler 1 is two relative semicircles with ruler 29 sections, the both sides of ruler 1 and ruler 29 are provided with graduation mark, one end of ruler 1 is provided with buckle 2, the other end is provided with a flat surface 3, and the centre of flat surface 3 is provided with pin-and-hole 4, is laid with a plurality of locating holes 5 on the flat surface 3 around the pin-and-hole 4; One side of ruler 29 is to face spigot surface 11 directly, and an end of ruler 29 cooperates the bayonet socket 10 of ruler one 1 one ends, and the other end is provided with buckle 2; Be installed with rotary steering piece 6 in the pin-and-hole of ruler 1, the bottom surface of rotary steering piece 6 is provided with a positioning boss 8 that cooperates with locating hole 5, and rotary steering piece 6 is provided with the gathering sill 7 of facing cooperation with ruler 29 directly.
A plurality of locating holes 5 around the pin-and-hole 4 on the flat surface are to be that 5 ° interval arranges along pin-and-hole circumference angle.
Form of a stroke or a combination of strokes dissection type drawing rule of the present invention, its major function replaces and surpassed complete set square, and is convenient aspect various angle lines and collateral line rendering; In addition, ruler one, ruler two all can be separately use as ruler, and connecting the buckle bayonet socket can become and add long ruler; Ruler one, ruler two dresses close also has the small tool kit function.Because simple in structure, the enterprise that generally has the plastic products ability all can produce, manufacturing cost can be low.
